Salomon C, Illanes, SE, Mitchell MD, Rice GEUniversity of Queensland Centre for Clinical Research, Australia

Complications of pregnancy are thought to be clinical manifestations of a common developmental lesion (i.e. inadequate invasion by extravillous trophoblast cells with a consequent failure to remodel maternal uterine spiral arteries). Available data support the hypothesis that dysfunctional exosomal signaling by placental cells contributes to this failure. Concomitant changes in the concentration of placental exosomes in pregnancies complicated by preeclampsia (PE), intrauterine growth restriction, preterm and gestational diabetes mellitus (GDM) may be prognostic and/or diagnostic of these complications. As such, the concentration, content and /or bioactivity of placenta-derived exosomes in maternal plasma may be informative of placental dysfunction. To test this hypothesis, placenta-derived exosomes present in maternal plasma during normal and complicated pregnancies (in this study, PE and GDM) were quantifi ed and characterised. Exosomes were isolated by differential and buoyant density centrifugation and characterised by nanoparticle tracking analysis, the expression of placenta and endosomal antigens, protein content and bioactivity. In normal pregnancies, the concentration, protein content and bioactivity of placenta-derived exosomes in maternal plasma varied signifi cantly with gestational age (p < 0.01). In pre-symptomatic GDM and PE pregnancies (< 20 weeks of gestation), the maternal plasma concentration of placenta-derived exosomes was more than two-fold that observed in controls. These data are consistent with the hypothesis that exosomes are released from the placenta during early pregnancy into maternal blood and may play a role in maternal adaptation to pregnancy. Gestational changes in the profi le and characteristics of exosomes in maternal blood may be of clinical utility in the diagnosis of placental dysfunction.

W1-3. Biology and chemistry of a mouse model with pregnancy-associated hypertension

Akiyoshi FukamizuLife Science Center, Tsukuba Advanced Research Alliance, University of Tsukuba, Tsukuba, Ibaraki 305-8577, Japan

Pregnancy-induced hypertension (PIH) is a serious complication during pregnancy and characterized by elevated blood pressure in late pregnancy with severe peripheral tissue damage and high mortality in fetus suffering from intrauterine growth retardation. It is estimated to affect 5% of all pregnancy all over the world with severe aftermath on both maternal and fetal health. Recent epidemiological studies indicate the association between PIH and cardiac morbidity and mortality during the postpartum period. In the medical treatment for chronic hypertension in non-pregnant state, angiotensin receptor blocker and angiotensin converting enzyme inhibitor are recommended as first-line therapy, but both are forbidden for female patients in pre- and post-partum periods due to possibility of fetal and neonatal abnormalities. Therefore, as a genetically engineered model animal, I will discuss the application of pregnancy-associated hypertensive mice.

W1-4. Exploration of preeclampsia model mice

Keiichi Kumasawa Department of Obstetrics and and Gynecology, Osaka University, Japan

Introduction: Preeclampsia is diagnosed by hypertension and proteinuria in pregnant women. When it becomes severe, it is threatening to both mothers and fetuses. It affects about 5% of pregnant women, and about 16% of maternal death were due to hypertensive disorders including preeclampsia. Thus far fundamental management is termination of pregnancy, and it comes to increase preterm births. Though this syndrome is reported from the ancient, for example Hippocrates’ book and a lot of researches have been done, the exact cause of preeclampsia is still unknown. It is partly because of the lack of appropriate model animals. Some animal models were produced by the systemic expression of sFLT1, but it did not reflect the fact that preeclampsia was due to some troubles in placenta.Methods: Thus far we explored placental specific lentiviral genetic transduction to mice, and this time we applied the way to make a more physiological model mice of preeclampsia. This time we focused on human soluble VEGF recepter1(hsFLT1)which was reported to be related with systemic symptom.Results: HsFLT1 overexpressing placentas led dams increasing blood pressure from E16.5 and proteinuria at E18.5. And both symptom disappeared after delivery, which mimicked human cases.Conclusions: We succeeded in making more physiologically preeclamptic model mice. And these mice can be suitable for exploration of therapy of preeclampsia.

W1-5. Pathogenesis of preeclampsia: COMT deficiency and its relevance.

Keizo KanasakiDepartment of Diabetology and Endocrinology, Kanazawa Medical University

Preeclampsia is a devastating pregnancy-associated hypertensive syndrome. Although it is quite common, the pathophysiology of preeclampsia is not yet clear, and it remains “the disease of theory”. We have been analyzing the relevance of catechol metabolism defect by catechol-o-methyltransferase (COMT) deficiency in the pathomechanisms of preeclampsia. We already showed that pregnant COMT deficient mice exhibited preeclampsia like phenotype; 2-methoxyestradiol, the estradiol metabolite via COMT, would rescue the

48 Abstracts for The 46th International Congress on Pathophysiology of Pregnancy

preeclampsia like phenotype by the restoration of placental oxygen status. Most of clinical analyze by others have been supported that COMT defi cient theory would be relevant for the pathogenesis of preeclampsia. Although convincing, we still need to demonstrate whether COMT defi ciency could explain key symptoms in preeclampsia. First, we analyzed the hypertension associated with COMT defi ciency is caused by relevant pathophysiological mechanisms as reported in preeclampsia. Regard with this, preeclampsia has been associated with hypersensitivity against vasoactive peptide. Second, we focused on glucose tolerance defects observed in preeclampsia and analyzed whether such glucose tolerance defects are explained by COMT defi ciency. In my talk, I would like to discuss about the working hypothesis about COMT defi ciency and preeclampsia including preliminary data obtained to support much deeper relevance of COMT defi ciency on preeclampsia pathogenesis.

W2-1. Rising prevalence of GDM in India – Challenges and opportunities

Hema DivakarImmediate past President FOGSI - India

There is overwhelming evidence of the magnitude of GDM in countries of South Asia. There is clear and adequate evidence that the magnitude of GDM in these countries is at a level that needs a holistic public health approach for appropriate intervention, in the form of universal screening of pregnant women.Variance in incidence have been reported in various literature, and this variance can be explained by the different methods and criteria used for diagnosis; There has been a signifi cant increase in the trend of prevalence of GDM over the past three decades, reaching to as high as 21% in some parts of India. But it is evident that the problem is a signifi cant one that needs programmatic intervention. Advocacy need to be directed to policy makers, programme managers, clinicians including obstetricians, and other health care providers. Women and the community are to be made aware and this should lead to demand generation, by which pregnant women will request to be tested for GDM. A strong message should also be communicated on the economic and development perspective that underscores the ‘invest in women’ message.

Mothers and diabetes is one of WDF’s eight focus areas. Focusing on gestational diabetes is a low-cost intervention both to improve maternal and child health but also to prevent future diabetes. Providing screening and care to mothers at risk of gestational diabetes is likely to have a multi-generational impact on the benefi ciaries as well as on health care systems and budgets.The talk will deliberate on issues revolving aroundDiffi culties when conducting screening for GDM and how to overcome themManagement of GDM, including diet, exercise and insulinImplications of uncontrolled/undiagnosed GDM on the mother and foetus/childUsage of glucometer / Importance of follow up during pregnancy /ReferralMotivation and education of mothers about screening, treatment and follow upObstetrical management in diabetes and pregnancy/Perinatal monitoring

Diabetes complicates about 3-10% of all pregnancies, with sensible variability related to racial differences. Frequency has significantly increased in last decades, with double rate incidence in all ethnical groups. In Italy, diabetes affecting pregnancies, according to ADA criteria before 2010, reaches 8-9% prevalence, and about 10% in migrating women.Diabetes and abnormal glucose metabolism during pregnancy may be pre-existing (diabetes type 1, 2, impaired glucose tolerance) or occur during pregnancy ( gestational diabetes ).To reduce maternal-fetal morbidity/mortality careful pregnancy planning for pregestational diabetes and early identification for gestational diabetes are fundamental.Gestational diabetes (GDM) screening is still controversial. In March 2010, the IADPSG criteria for GDM was accepted by Italian Consensus Conference. Comparing estimates of GDM prevalence, calculated by new and old diagnostic criteria, among Italian population, a strongly significant increase in gestational diabetes prevalence emerges ( + 136.8%), which decreases when results are compared to different historic categories of impaired gestational glucose metabolism ( + 33.8%). Since 2011, screening has been restricted from universal to selected on the basis of low, medium and high risk factors for GDM.The “ Italian Model ” evolution of screening and managing diabetes in pregnancy and its impact will be addressed and discussed.

W2-3. Clinical features of gestational diabetes mellitus by the new consensus criteria: Three year experience in a single institution in Japan.

Kei MiyakoshiDepartment of Obstetrics and Gynecology, School of Medicine, Keio University

There is a paucity of information on perinatal data regarding gestational diabetes mellitus (GDM) by the new criteria from a real experience because the number of healthcare associations implementing the criteria is still limited. In Japan, the new recommendation was adopted in 2010, and is commonly used in the obstetric practice. In our hospital, women with GDM underwent self-monitoring of blood glucose measurements as well as dietary management. Additionally, insulin treatment was initiated when dietary treatment did not achieve the glycemic goal. Using a cohort of women with singleton pregnancy receiving perinatal care at our hospital between 2011 and 2013, clinical features of new criteria-defined GDM were reviewed. The incidence of GDM was 14%, mainly by one abnormal OGTT value (1-AV). GDM women with 1-AV showed less severe glucose intolerance than those with two or three abnormal OGTT values, but appeared at high risk of insulin requirement when a family history of diabetes existed. When compared perinatal outcomes between women with normal glucose tolerance and GDM, fetal growth were comparable between the two groups. Medical intervention for women with new criteria-defined GDM could contribute to the improvement of pregnancy outcomes, although further studies on the clinical and cost-effective management are needed. Our data would be useful for healthcare professionals considering the new criteria.

W2-4. Management for mild gestational diabetes in Japan: messages from a retrospective multi-institutional study

Takashi SugiyamaDepartment of Obstetrics and Gynecology, Tohoku University Graduate School of Medicine

In 2010, the criteria for diagnosing GDM proposed by the IADPSG were adopted in Japan. The frequency of GDM consequently increased 2 to 4 fold as compared with the previous criteria. Among women with newly-diagnosed GDM, most had only one abnormal value (OAV) based on the previous criteria. A multi-institutional retrospective review was thus performed by the Japan GDM Study Group to assess whether the treatment of mild GDM, i.e., one abnormal 75-g OGTT value, improves pregnancy outcomes in Japan.In a multi-institutional retrospective study, we examined pregnant women meeting the criteria for mild GDM (i.e., OAV for 75-g OGTT; fasting glucose ≥ 100 mg/dL, 1-h postprandial glucose ≥ 180 mg/dL, and 2-h postprandial glucose ≥ 150 mg/dL), receiving either routine prenatal care (non-treatment group: 542 women) or dietary intervention alone or dietary intervention with self-monitoring of blood glucose and/or insulin therapy, if necessary (treatment group: 351 women). Pregnancy outcomes were compared between these groups.Multiple logistic regression analysis (MLRA) revealed that pre-pregnancy BMI and gestational weight gain were associated with LGA infants, while 75-g OGTT results were unrelated to LGA. When overweight and obese women were the subjects, the number of LGA infants was significantly lower in the intervention than in the control group, and gestational weight gain was significantly lower in the treatment than in the control group. MLRA showed that intervention was significantly related to a lower incidence of LGA infants.This study suggests that maternal BMI impacts fetal growth and that treatment for overweight or obese mothers with OAV is associated with a lower frequency of LGA infants.

W2-5. Adipocytokines in gestational diabetes mellitus and offspring’s metabolic syndrome

Hisashi Masuyama, Yuji HiramatsuDepartment of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences

Normal pregnancy is characterized by insulin resistance, which contributes to development of gestational diabetes mellitus (GDM) and preeclampsia. Obesity is one of risk factors for GDM and preeclampsia, while dysregulation of adipocytokines, such as leptin and adiponectin, due to obesity cause abnormal glucose and lipid metabolism and insulin resistance. In addition, obesity and insulin resistance in the mother might play a direct role in the transmission of an obesogenic and diabetogenic trait from generation to generation, but the role of genes and a shared environment are not completely understood. We demonstrated that adiponectin level and insulin sensitivity were significantly decreased in GDM patients compared with normal glucose tolerance in obese women. Minor alterations in angiogenic factor concentrations, elevated insulin resistance and mildly elevated adiponectin level may be involved in the pathophysiology of late-onset preeclampsia in obese patients. We also observed that a high fat diet (HFD) induced obesity in pregnant mice resulted in hypertension, proteinuria, and macrosomia with insulin resistance and abnormal adipocytokine levels and that the exposure to an HFD in utero might lead to a metabolic syndrome-like phenomenon through epigenetic modifications of the genes encoding adipocytokines, adiponectin and leptin in the offspring.These data suggested that adipocytokines might play important roles in pathophysiology of GDM and late-onset preeclampsia in obese women and in the origin of metabolic syndrome in adulthood of offspring.

W3-1. Endothelial dysfunction in the pathogenesis of preeclampsia

Keiichi MatsubaraDepartment of Obstetrics and Gynecology, Ehime University School of Medicine

Early in pregnancy, abundant neovascularization at the implantation site is important for normal placentation, so that suffi cient nutrients and oxygen can reach the fetus. For placental development and reduction of uterine vascular resistance, cytotrophoblasts must migrate to the decidua and the uterine myometrium, with subsequent invasion of the spiral arteries. Cytotrophoblasts replace the endothelium in the spiral arteries, reduce vascular resistance, and increase the blood supply to the fetus. However, in preeclampsia, the reconstitution of spiral arteries does not extend to the myometrium, which leads to poor placentation, defi cient fetal blood supply, placental ischemia, and fetal growth restriction. The resulting increased peripheral vascular resistance leads to maternal hypertension. The vascular dysfunction is mediated by the imbalance of serum factors including nitric oxide and reactive oxygen species, angiotensin II receptor subtype 1 and subtype 2, etc. The imbalance is deeply involved in the pathophysiology of preeclampsia through the endothelial dysfunction.

W3-2. Lysophosphatidic acid signaling as a functional modulator of trophoblasts and its relevance to the pathology of preeclampsia

Department of Obstetrics and Gynecology, The University of Tokyo

Lysophosphatidic acid (LPA) is a novel lipid mediator produced mediated by enzymatic action of a secretary peptide, autotaxin (ATX). In past works, LPA receptor 3 (LPAR3) is localized to reproductive organs and gene deletion mice have demonstrated a critical role of LPA-LPA3R axis in implantation. This study aimed to examine the involvement of LPA:LPAR3 signaling in the regulation of trophoblast cell function. The association of this signaling pathway with the etiology of preeclampsia (PE) was also investigated.Immunohistochemical staining of human placenta indicated a constant ATX production in all trophoblast types, whereas LPAR3 expression was limited to differentiated trophoblast population including extra-villous trophoblasts and syncytiotrophoblast. The alteration in gene expression profi le in LPAR3-transfected HTR8/SVneo upon a stimulation with a specifi c agonist, T13 was performed using DNA array analysis. LPAR3 stimulation evoked up-regulation of the expression for gene groups related to eicosanoid synthesis, cell differentiation and cytokines/chemokines which were reported to play signifi cant roles in fetomaternal immunity. These observations imply that LPA:LPAR3 axis controls trophoblast activities, consequently leading to healthy placentation.In the analysis on the peripheral blood from women with PE, reduced ATX concentration was observed prior to the manifestation of clinical symptoms. ATX mRNA level was lower in preeclamptic placentas compared with normal placentas. Interestingly, the degree of ATX mRNA reduction was more remarkable in early onset type than in late onset type. Considering the close link of impaired placental formation with early onset type, the aberrant function of LPA signaling might be one of pathogenic factors for PE.

W3-3. Adipocytokine and inflammation in preeclampsia

Katsuhiko NaruseObstetrics & Gynecology, Nara Medical University, Kashihara, Nara Japan

Inflammation and insulin resistance in pregnancy are mainly produced by placenta and adipose tissue. The pathological change of preeclampsia (PE) is manifested on third trimester of pregnancy, after the increase in physiological load of pregnancy on the basis of early placentation failure. Most of the cytokines derived from adipose tissue (adipocytokines) were similarly altered in the patients with a normal pregnancy course and PE. However, chemokine MCP-1 level was decreased in the normal pregnancy group but increased in the PE, indicating the adipocytokine-induced pathological inflammation in PE. We also performed novel culture method of adipose tissue with or without serum samples from PE patients, and performed PCR array of inflammatory genes. Altered genes were related to chemokine and toll-like receptor (“homeostatic inflammation”), which plays a central role in systemic inflammation of PE.We also measured RAGE (receptor for advanced glycation endproducts)-ligands, a major “Danger Signal” in the human body. Levels of HMGB1 and S100A12 were increased in patients with PE. Especially, an increase in HMGB1 level may support the 2-step theory, that the molecule is regarded as a surface marker of trophoblast-derived “microparticles”. Pathological mechanism of PE may include both placentation failure and inflammatory response of adipose tissue.

W3-4. Angiogenic factors in preeclampsia

Kaori KogaObstetrics and Gynecology, the University of Tokyo, Japan

Soluble fms-like tyrosine kinase 1 (sFlt1) is a splice variant of Flt1, acts as a potent antagonist for vascular endothelial growth factor (VEGF) and placental growth factor (PlGF). We found that the level of sFlt1 in serum from women with preeclampsia was ~ > 6-fold higher than that from control. This may point to an involvement of sFlt1 in the pathophysiology of preeclampsia possibly by antagonizing of VEGF/PlGF effects on the formation of placental vasculature and maternal endothelial cell function (Koga et al 2003). Furthermore, we and other groups demonstrated that the elevation of serum sFlt1 preceded the manifestation of preeclampsia, which suggests a potential of this molecule as a diagnostic marker.Serum sFlt1 levels were also shown to be elevated in conditions that may predispose mothers to preeclampsia, such as a twin pregnancy and certain viral infections. We have demonstrated that sera from patients with hydatidiform mole, a condition also known to cause severe preeclampsia in early pregnancy, contain high level of sFlt1, and the level decreases markedly after the evacuation of molar tissue (Koga et al 2010). These findings imply that serum sFlt1 is derived from the placenta and sFlt1 may cause preeclamptic symptom despite the absence of fetus.We will also introduce factors that may up-regulate sFlt1 expression in trophoblasts, such as hypoxia and thrombin (Zhao et al 2012). These understanding may contribute to the development of novel strategies for prevention/ treatment of this dysfunction.

W3-5. Management preeclampsia

Gus Dekker

University of Adelaide, Australia

Preeclampsia is a progressive disorder that will inevitably worsen if pregnancy continues. Current therapy does not ameliorate the placental pathology nor alter the pathophysiology or natural history of preeclampsia. Delivery is the definitive management and is followed by resolution, generally over a few days but sometimes much longer. At mature gestational age (37 weeks and more), delivery should not be delayed. Even so, it is important to control severe hypertension and other maternal derangements before subjecting the woman to the stresses of delivery. Prolongation of pregnancy in the presence of preeclampsia carries no benefit for the mother but is desirable at early gestations to improve the fetal prognosis as in general, fetal outcome is proportional to gestational age at delivery. In cases of preterm preeclampsia before 34 weeks, delivery should be delayed for at least 24-48 hours if maternal and fetal status permit, to allow fetal benefit from antenatal corticosteroids administered for lung maturation. A number of trials have shown that 25-30% of women managed expectantly with preeclampsia will develop severe morbidity including HELLP syndrome, abruption, pulmonary edema and eclampsia and that the mean duration of prolongation is less than 12 days. It should be noted that this rate of complications also exists in patient managed with prompt delivery. Continuation also carries fetal risk and some stillbirths will occur despite careful monitoring.The management of women with preeclampsia between gestational ages of 24-32 weeks should be restricted to those centres with appropriate experience and expertise. Clear “endpoints” for delivery should be defined for each patient such that the decision to terminate the pregnancy is based on agreed criteria. In many cases, the timing of delivery will be based upon a number of factors, maternal and/or fetal rather than a single absolute indication for delivery. For preeclampsia prior to 24 weeks gestation, termination of pregnancy is almost universally the best option.

W4-1. PPH – Lessons from confi dential inquiries – thoughts for the future

S. ArulkumaranProfessor Emeritus, St George’s University of London, England

The stepwise rapid succession of medical followed by surgical interventions can stop or minimize the bleeding and correct the blood loss and prevent the cascade of events that lead to massive blood loss, hysterectomy, admission to ICU and deaths. ‘Too little, too late’ has been highlighted in successive confi dential enquiries into maternal deaths in the UK. The phenomenon of ‘too little, too late’ can be tackled by the use of the mnemonic ‘HAEMOSTASIS’.H - Ask for HelpA - Assess (vital parameters, blood loss) and ResuscitateE - Establish etiology, Ensure availability of blood. EcbolicsM - Massage Uterus – bimanual compressionO - Oxytocin infusion / prostaglandins -S - Shift to theatre – to exclude retained products and trauma/ bimanual compression/ Antishock garment/ Aortic compressionT - Tamponade – Balloon / uterine packing / tranexamic acid - exclude ‘tissue and tears’A - Apply compression sutures –S - Systematic Pelvic devascularisationI - Interventional - Uterine artery embolisationS - Subtotal / Total abdominal hysterectomyGive oxygen, adequate fl uids, blood and blood products. No response to oxytocin or, ergometrine warrants infusion of oxytocin to keep the uterus contracted to allow clotting of uterine vessels. Next step is bimanual uterine massage and prostaglandins (parenteral PGF or misoprosotol PG E1 orally or sublingually -600 micrograms). Blood loss could be about 70 ml/min when the uterus relaxes and hence a 14 Gauge needle to give fl uids rapidly should be used X 2 lines. Tranexamic acid 1-2 gm intravenously, an antithrombolytic prevents the clot from lysing. An antishock garment which squeezes the blood into the circulation and also has a compressive effect on the uterus could be tried. Consumptive coagulopathy, lack of clotting factors, activation of fi brinolysis, large volumes of fl uids, metabolic acidosis and hypothermia aggravates the situation and is controlled by fi brinogen and clotting factors. Shock is proportionate to blood loss - mild 15%, moderate 30%, and severe 45%. Transfusion of one unit packed red blood cells to unit plasma as opposed to four packed cells to one unit plasma results in a 60 to 70% reduction in mortality in war injury victims -same principle after blood loss of > 2L of blood loss is useful. Freeze dried fi brinogen concentrate that can be reconstituted may be an alternative. Platelet transfusion may be needed but this is rare. Failure to arrest haemorrhage by medical therapy should be followed by a ‘Tamponade Test’. It will only work when there is no coagulopathy. Sengstaken, Rusche, Cooke’s catheter or condom or rubber glove tied to a plastic catheter can be inserted into the uterus and fi lled with warm saline/ water bleeding completely stops. If bleeding stops the balloon can be taken out in 6 hours. Patient should have broad spectrum antibiotics and an oxytocin infusion. Vital parameters, fundal height and bleeding per vagina should be monitored. If the test is going to be effective it will be known within 5 minutes. If the tamponade fails to stop the bleeding, a laparotomy should be performed and compression sutures (B- lynch or 2 to 5 vertical) should be employed. Failure of compression sutures should lead to systematic devascularisation by tying the infundibulopelvic and uterine vessels and/or anterior branch of the internal iliacs. Arterial embolisation using radiological guidance can be tried where facilities exist. Failure to arrest haemorrhage or deterioration of general condition of the patient should prompt sub-total or total hysterectomy.

W4-2. Massive primary postpartum hemorrhage: embolization or hysterectomy?

Jin-Chung ShihDepartment of Obstetrics and Gynecology, National Taiwan University Hospital, Taipei, Taiwan

Postpartum hemorrhage (PPH) due to various etiologies, including uterine atony and abnormal placentation, represents the most common cause of maternal mortality in the developed world. Traditional management consists of peripartum hysterectomy, selective hypogastric artery ligation, and more conservative approaches such pharmaceutical and uterine embolization have also been advocated recently. Substandard care and ‘too little being done too late’ remain a signifi cant debate between different series. For massive primary PPH, should

57Abstracts for The 46th International Congress on Pathophysiology of Pregnancy

we go straightforward to hysterectomy? Some authors may think embolization should be considered as the first choice? There is no consensus at current era. In this brief talk, I try to review the existing literature and compare the efficacy and complications of these two procedures.The authors may favor hysterectomy as the first priority for PPH mainly because of the rich collateral of blood supply to the uteus. The hemostasis effect of emboliation for placenta accreta cannot sustain a long period. Besides, a number of complications (such as bladder ischemia, thrombosis) result from embolization were ever reported. These efficacy/complications distract the routine use of uterine embolization as the first line treatment of PPH.However, surgical intervention for massive primary PPH needs a detailed preparation of surgery, including instrument and transfusion. Besides, hysterectomy needs a carefully dissection of adjacent organs (such as bladder and bowel), which may result in more severe surgical complications than PPH itself. Finally, continuous bleeding from the wound of hysterectomy due to placenta accreta is usually substantial. Based on these reasons, some authorities do not favor hysterectomy as the line treatment for massive primary PPH.

W4-3. Usefulness of balloon tamponade and compression suture for massive uterine bleeding

Shintaro MakinoJuntendo University

Objective: Various surgical hemostatic methods for postpartum hemorrhage have been reported. The aim of this study was to evaluate the usefulness of balloon tamponade and compression sutures for controlling uterine bleeding. Methods: We analyzed 146 patients who showed massive uterine bleeding (vaginal delivery > 1,000mL (n = 26), cesarean delivery > 2,000mL (n = 120)) about hemostatic methods and their prognosis. Hemostatic methods include bimanual compression, additional oxytocin injection, balloon tamponade, compression sutures, transcatheter arterial embolization (TAE) and hysterectomy. Results: Balloon tamponade was employed for 12 cases after vaginal delivery and TAE was performed for 1 case who was diagnosed as failure of balloon tamponade. Vertical compression sutures were used in 7 cases and 1 of these cases needed additional suture of uterine body because of atonic bleeding. In this case, hysterectomy was performed because of failure of compression suture.Conclusions: The balloon tamponade and vertical compression suture are simple, easy, and effective for controlling bleeding in women with PPH. We now believe that these technique should be performed to avoid excess TAE or hysterectomy. Subsequent menstruation resume and pregnancy will also be discussed in this presentation.

W4-4. Management of postpartum hemorrhage

Eiji KondohAssociate Professor, Department of Gynecology and Obstetrics, Kyoto University, Graduate School of Medicine, Kyoto 606-8507, Japan

Postpartum hemorrhage (PPH) is one of the leading causes of maternal morbidity and mortality worldwide. The causes of PPH include uterine atony, genital tract lacerations, and placenta previa. When PPH persists despite conventional conservative treatments, we sometimes face difficult decisions on whether and to what extent hemostatic interventions (e.g. intrauterine balloon tamponade, radiological intervention, and hysterectomy) should be conducted. Here, I would like to introduce treatment decision-making for PPH using dynamic CT, and how we have improved the success rate of intrauterine balloon tamponade.Placenta previa accreta (PPA) is a potentially life-threatening obstetric condition, and has become increasingly common with the rising rate of cesarean deliveries. Conservative management, leaving the placenta behind, has gradually been accepted because it can reduce hemorrhage, preserve fertility, and prevent damage to the surrounding tissue. I will show that intrauterine balloon tamponade can be a useful addition to the options for the conservative management of PPA when partial detachment of the placenta causes intraoperative massive hemorrhage. Moreover, I present a complete observational cohort of every attempted case of conservative management in our institution. In each case the placenta vanished spontaneously and none of the patients required hysterectomy. Serial alterations in the placenta and its blood flow will be demonstrated using ultrasonography and dynamic MRI along with monitoring of serum beta hCG levels in the postpartum period.

W4-5. Management of Coagulopathy (Obstetrical DIC)

Atsuo ItakuraDepartment of Obstetrics and Gynecology, Juntendo University

Postpartum hemorrhage (PPH) often complicates dilutional or consumptive coagulopathy (obstetrical DIC), and obstetrical DIC may lead to life-threatening uterine or microvascular bleeding. Substitution with blood products containing coagulation factors is necessary for managing such patients. Although substitution of fibrinogen concentrate (FC) or cryoprecipitate is the standard treatment for obstetrical DIC in several developed countries, fresh frozen plasma (FFP) transfusion still has been used as the standard treatment for microvascular bleeding in Japan. So we have administered off-label FC for obstetrical DIC cases. To assess the efficacy and safety of FC in the treatment of obstetrical DIC, we reviewed medical records (2006-2011) of such cases. The overall response to FC was considered good in 12 cases, moderate in 4, and poor in 2. Fibrinogen levels significantly increased after FC substitution (approximately 40 mg/L/g FC). No serious adverse events were causally associated with FC substitution therapy. Then we created a new transfusion protocol for obstetrical DIC, in which FC and FFP are administered according to PT% and plasma fibrinogen value. We evaluated the usefulness of our protocol by comparing the prognosis of obstetrical DIC patients before and after the implementation of the protocol. FFP transfusion amount, FFP/RCC ratio, and mean blood loss were reduced significantly after the introduction of the protocol. There were no adverse events associated with the protocol. Our transfusion protocol, taking priority of FC, is effective and safe for the treatment of obstetrical DIC.

Aim: The aim of this study was to assess the rate of eclampsia in Japanese women and the relationship between changes in blood pressure (BP) and eclamptic episode.Methods: We used the perinatal database of the Japan Society of Obstetrics and Gynecology to access 330,399 deliveries after 22 weeks of gestation across 125 centers of the perinatal network between 2005 and 2009. A total of 246 women with eclampsia were identifi ed. The main outcome measures used were incidence, maternal age, body mass index (BMI), parity, gestational age at delivery, and mortality rate. We retrospectively investigated the severity of BP elevation just before eclamptic episode.Results: We identifi ed a total of 246 cases of eclampsia which corresponded to an incidence of 7.4/10,000 deliveries with a mean age of onset of 30.7 ± 5.8 years. The proportion of primiparous women was 81.3%, and the mean gestational age at delivery was 36.7 ± 4.0 weeks. Four maternal deaths were identifi ed. Systolic BPs just before eclamptic episodes in 11 eclamptic patients were160 mmHg or more.Conclusions: The rate of eclampsia in Japanese women was 7.4/10,000 deliveries. The risk of eclamptic episode may be higher in 160 mmHg or more of systolic BP.

W5-2. Management of eclampsia and stroke during pregnancy

Yasumasa OhnoOhno Ladies Clinic

Eclampsia and stroke during pregnancy are major causes of maternal and neonatal death. To establish the etiologies and therapeutic strategies for the eclampsia and stroke during pregnancy, we performed a questionnaire based study in Aichi prefecture.This study revealed the following findings: 66% of deliveries were managed in primary medical institutions, 38% of eclampsia and 39% of stroke occurred at primary medical institutions, and 26% of stroke occurred at home.We investigated cases of eclampsia and/or stroke during pregnancy and revealed important issues regarding their management. In case with eclampsia, accurate antihypertensive and anticonvulsive treatment are necessary. Discriminating between eclampsia and stroke is difficult. However, when unconsciousness, facial muscle weakness, arm muscle weakness or a facial deficit is detected, stroke should be suspected. Brain CT can detected most of hemorrhagic strokes. When a stroke is detected, collaborative treatment with neurosurgeons should be started. If stroke is suspected at a primary medical institution, rapid maternal transport to an intensive medical institution is necessary. In patient whose blood pressure is greater than 180/120mmHg, the reduction of their blood pressure should be performed rapidly.These findings might aid the development of therapeutic strategies for pregnant women with eclampsia or stroke.

W5-3. Determination of antithrombin activity (AT) enhances “Safety” of the management of pregnant women, especially in women with multifetal pregnancies, hypertension, proteinuria, or edema

Hisanori Minakami, Mamoru Morikawa, Takahiro Yamada, Rina AkaishiDepartment of Obstetrics, Hokkaido University Graduate School of Medicine, Sapporo, Japan

Monitoring of platelet counts helps to identify early women with at higher risk of HELLP syndrome. However, some women with liver dysfunction similar to the HELLP syndrome do not exhibit thrombocytopnenia, but almost all of such women exhibit pregnancy-induced AT deficiency (PIATD) defined as a gradual decrease in AT activity until the time of delivery, with AT activity reaching < 65% of the normal activity level. These women are diagnosed clinically as having acute fatty liver of pregnancy (AFLP).Although PIATD is likely to occur in women with hypertensive disorders including gestational hypertension and preeclampsia (approximately 20% and 1.0% for women with and without hypertension, respectively), it occurs frequently and independently of hypertension in multifetal pregnancies (10%, and 40% for twin and triplet pregnancies, respectively). This explains why women with multifetal pregnancies are likely to develop AFLP. The PIATD is also likely to occur in the absence of hypertension in women with isolated proteinuria or isolated edema. Ascites frequently seen in patients with preeclampsia contains abundant AT, suggesting that AT escapes from the blood into the interstitial space in the presence of an increased vascular permeability. Women with PIATD show a large and sustained decrease in the hematocrit value after delivery irrespective of the presence or absence of hypertension, suggesting a severe antenatal hemoconcentration and a decrease in the plasma volume in women with PIATD. Thus, AT activity in obstetrical practice enhances the “safety” of the management of pregnant women.

Emergency Critical care in India is oft necessary in the context of hypertensive disorders in Pregnancy (HDP) especially eclampsia and Hemorrhagic problems such as antepartum and postpartum hemorrhage. Atonic postpartum hemorrhage continues to be a serious problem. So does eclampsia and other complications of HDP. Anemia is an important background risk which aggravates the situation. Uterine inversion, fulminant liver diseases, ARDS, rupture uterus due to misoprostol use are some other causesEctopic pregnancies too are on the rise. Fetal emergencies such as bradycardia, obstructed labour cordprolapse, preterm delivery too are common.The country still battles with a high maternal mortality and morbidity though many measures have been undertaken by the government, the private sector and organizations such as the FOGSI

The antihypertensive therapy for the hypertensive disorders of pregnancy needs controllable and stable managements for protecting the antepartum feto-maternal circulations along with unstable postpartum circulatory conditions. Eclampsia and HELLP syndrome are the major and the most hazardous involvements in these diseases with easy to accompany with severe hypertension. Effective and maintained managements are preferable for these maternal organ involvements.Nicardipine (Nic) is the only intravenous calcium channel blockade with effective and controllable dose-response reaction. Also, we had elucidated that the elevating diastolic blood pressure (dBP) is related to the maternal organ involvements in the disease of hypertensive disorders in pregnancy. We had applied the Nic drip infusion against the disease of hypertension in pregnancy under referring to dBP. And for the safe and maintained management, Nic is started at low dose and increased in the dose in pre-ordered stepwise manner toward target dBP. We studied the change of BP in the cases of eclampisa with progressing state, and elucidated the efficacy of stepwise management with referring to dBP.We will show the effectiveness and safety the antihypertensive treatment of Nic stepwise protocol with starting at low dose and referring to dBP for the management of eclampsia along with HELLP syndrome complicating with severe thrombocytopenia below 50 × 103/mm3. And it is proposed that targeting dBP below 90 mmHg (systolic below 140 mmHg only in the isolated systolic hypertension) should be the safe way to treating eclampsia and HELLP syndrome.

W5-6. Correlation of Thrombocytopenia and LDH levels in patients with pregnancy hypertension and its comparison with normotensive pregnant women

Bhumija SharmaOBGY, Bharati Vidyapeeth Hospital and Medical College, Pune, India

Pre-eclampsia affects approximately 5–8% of pregnant women. The common hematological disorder in preeclampsia is thrombocytopenia. LDH refl ects the severity and occurrence of complications in preclampsia. Both these are useful in predicting the progression of severe preclampsia and identifi cation of HELLP syndrome . The aim of this study is to assess the levels of platelet count and serum LDH levels in patients with preclampsia and its comparison in normotensive pregnant patients so as to observe the levels which are specifi c to severity of preclampsia and infl uence decision making in obstetric intervention. It is a prospective observational study in which a total of 40 ANC patients are included, 20 of which were diagnosed to have raised blood pressure and rest of the 20 were normotensive patients at 36 weeks of gestation. Pre-eclampsia criteria were: Blood pressure more than or equal to 140/ 90 mm Hg and proteinuria greater or equal to 300 mg/ 24hours urine sample in the third trimester. Platelet, and LDH were measured. Data were analyzed by the mean of SPSS-14 program & Chi-2 or t-student were used. Both the groups were comparable in context of age and parity .10 had mild preeclampsia while 10 had severe preeclampsia. Three normotensive subjects were found to have thrombocytopenia and 15 subjects had abnormal LDH level ( > 600IU). In comparison with preeclampsia group thrombocytopenia and LDH levels are not signifi cantly different. However they are markedly abnormal in severe hypertension are infl uenced by co-existence of anemia. These laboratory parameters also infl uence obstetric decision making and are associated with fetal distress. The study concludes that thrombocytopenia and LDH levels are not specifi c parameters to diagnose the disease but are associated with fetal distress.

W6-1. Decidual cellular senescence contributes to preterm delivery.

Yasushi HirotaDepartment of Obstetrics and Gynecology, Graduate School of Medicine, The University of Tokyo, Japan

Preterm delivery is a major global health issue, and its causes and underlying mechanism remain unclear. We recently established a mouse model of spontaneous preterm birth. In this model, decidual cellular senescence early in pregnancy via mTOR-p21 signaling is a major contributor of preterm delivery and fetal death, and these adverse phenotypes are restored by the inhibition of mTOR or p21. This role of decidual cellular senescence in determining the timing of birth in mouse models may help us better understand the mechanism of the timing of birth in humans and develop new and improved strategies against preterm delivery.

Background: The events of parturition are similar to those of an inflammatory response. Previously we demonstrated that local chemotactic activity increases as gestation progressed. However, the issue of whether leukocyte responsiveness changes during pregnancy was not addressed. We hypothesized that leukocyte responsiveness to a chemotactic signal increases as gestation progresses.Methods: Proteins were isolated from fetal membranes. Blood was drawn from 5 different groups of patients; term in labour (TL), term not in labour (TNL), preterm in labour (PTL), threatened preterm labor (TPTL), fluid leakage (pPROM) and preterm not in labor (PTNL). Isolated leukocytes and chemotactic extracts were placed into a Boyden chamber. Migrated leukocytes were quantitated using flowcytometry. The expressions of 5 chemokine receptor mRNA abundance in leukocytes were assessed using quantitative RT-PCR.Results: Leukocyte responsiveness increased to term chemotactic signals as labor progressed (p < 0.0001). Subanalysis revealed spontaneous TL leukocytes migrated more than induced labor leukocytes (p < 0.05). PTL and pPROM leukocytes migrated more than PTNL and TPTL leukocytes (p < 0.05). However, chemokine receptors expression did not change in any group.Conclusions: This is the first report that human leukocytes increase their responsiveness to chemotactic signals as labor progresses. This approach can be used to establish a preterm labor prediction test. The lack of change in leukocyte chemokine receptor expression suggests the intriguing possibility of a different type of chemoattractant.

W6-3. Trial for prevention of preterm birth in Japan

Katsufumi OtsukiChief and Associate Professor, Department of Obstetrics and Gynecology, Showa University Koto Toyosu Hospital

The perinatal mortality rate in Japan is the lowest in the world, but the mortality rate is high for preterm infants born at less than 30 weeks gestation. Moreover, even if they survive, preterm infants face a wide variety of problems. To improve prognosis for these infants, focus must be placed not only on improvements in neonatal care, but also on reducing preterm deliveries themselves. Based on recent research, new markers and methods for testing for threatened preterm delivery are being clinically introduced, but we are currently still at the stage of exploring how such new test methods and knowledge can be utilized in actual clinical practice to prevent preterm deliveries. Clinical research is rapidly advancing in this area. As we cannot just rely on the results of foreign research in this field, research that has been adapted to the specific conditions of perinatal care in Japan is crucial. However, due to the small scale of medical facilities in Japan, we have yet to see reports of good clinical research using the principles of evidence-based medicine. Thus, for the present study, we organized a group composed mainly of university hospitals and general perinatal care centers in Japan and conducted a full-scale randomized comparative clinical trial with the objective of preventing preterm deliveries, the most important topic in perinatal care. Therefore, the objective of our multicenter, randomized, controlled trial was to assess the benefits of some treatments on women with ultrasound-diagnosed cervical shortening in the mid-trimester to prevent preterm birth.

Satoshi Yoneda, Noriko Yoneda, Mika Ito, Arihiro Shiozaki, Shigeru SaitoDepartment of Obstetrics & Gynecology, University of Toyama, Toyama-Shi, Toyama 930-0194. Japan

Objective:To examine whether antibiotic therapy is useful to prevent preterm birth.Study design:Ninety-one preterm labors with intact membrane less than 32 weeks of gestation were enrolled. They were all managed in our hospital and obtained informed consent for amniocentesis. Amniotic fluid microbes were detected by newly established - high sensitivity PCR method. Cephalosporin iv infusion were performed in bacteria only cases, and antibiotic macrolide therapy was performed to Ureaplasma / Mycoplasma only cases, or the both therapies were performed to coinfection cases. We evaluated the correlations between the prolonged gestational days and the appropriate antibiotic therapy (AAT), including the cerclage, 17-OHPC, and urine trypsin inhibitor (UTI).Results:AAT was the independent factor to influence the prolonged gestational days in regression analysis (P = 0.0002). In the negative microbe group (n = 58), the prolonged gestational days in the administration of antibiotics were significantly shorter than that of no administration (P = 0.0109). While in the positive group (n = 33), AAT tended to prolong the gestational days, compared with no AAT (P = 0.0734). The frequency of neonatal sepsis, and chronic lung disease did not increase in AAT group.Conclusion:The appropriate antibiotic therapy may be a useful therapy for prolongation of gestational days in preterm labor.

W6-5. Antenatal corticosteroids; Anything new after Liggins?

Alex C. Vidaeff

Baylor College of Medicine, Houston, USA

The administration of antenatal corticosteroids is one of the most effective and important therapies in prenatal medicine. Clearly, antenatal corticosteroids have very substantial immediate benefits for preterm infants with few known side effects.Several aspects are still the subject of ongoing controversy and uncertainty such as the ideal drug formulation, timing of treatment, or the applicability to specific clinical conditions. Growth restricted fetuses contribute to a subset of preterm infants that may be particularly vulnerable to corticosteroid therapy and the potential adverse effects of corticosteroids in this clinical context continue to be debated. Our presentation will point out questions that still need answers and represent current priority areas for future research intended to devise ways in which the effectiveness and safety of antenatal corticosteroids can be enhanced.

Currently, preeclampsia (PE) and gestational hypertension (GH) are considered either separate diseases affecting similar organs or different severities of the same underlying disorder. Using data from women with no essential hypertension and with singleton births between 2001 and 2005 after 22 weeks of gestation at 125 centers in Japan (Japan Perinatal Registry Network Hospitals), we focused on the difference in risk factors and in perinatal outcomes between GH and PE. Of 241,292 women, 2,808 (1.2%) developed GH and 6,423 (2.7%) developed PE. Thirty-fi ve years or older, primiparity, diabetes mellitus, and renal disease increased the risk of both GH and PE. Forty years or older was a factor only for GH, while primiparity, female fetus, and renal disease were risk factors only for PE. Early-onset (before 32 weeks of gestation) was a common risk small-for-gestational age (SGA) in GH and PE, but in late-onset only PE was a risk factor for SGA. Main population of SGA infants was composed of PE cases because PE accounted for 83.3% of early-onset type before 32 weeks. Girl preponderance in the PE women was observed (sex ratio: boys/girls = 0.904), while slight boy preponderance was seen in normotensive women (1.06) and GH (1.02). These fi ndings suggest that PE and GH seem to be independent entities.

W7-2. Outcome of pregnancy with isolated proteinuria - gestational proteinuria can detect the onset of preeclampsia

Mamoru MorikawaDepartment of Obstetrics, Hokkaido University Graduate School of Medicine

In 2005, the Japanese Society of Obstetrics and Gynecology revised the criteria for pregnancy-induced hypertension and adopted new criteria in which PIH was defined as hypertension with or without proteinuria occurring at and after 20 weeks of gestation, but resolving 12 weeks postpartum. PIH includes preeclampsia (hypertension with proteinuria), gestational hypertension (hypertension without proteinuria) and superimposed preeclampsia. Women with proteinuria alone are not diagnosed with preeclampsia until they exhibit additional hypertension, and those who do not develop hypertension are diagnosed as having gestational proteinuria at 12 weeks postpartum. Thus, gestational proteinuria is a retrospective diagnosis.I. Problems in methods for the detection of significant proteinuria in pregnancy and for the diagnosis of gestational proteinuria.Dipstick test and P-test were likely to over- and underestimate risks of significantproteinuria, respectively. Thus, the spot-urine protein-to-creatinine ratio (P/Cr test) would be used. The 24-h urine collection was often incomplete. Repeated positive dipstick test results in two successive antenatal visits warrant a need for a confirmation test of significant proteinuria.II. Gestational proteinuria can detect the onset of preeclampsiaWomen with new-onset proteinuria in the absence of hypertension may be more likely to progress to preeclampsia than women with a presumptive diagnosis of gestational hypertension, and the likelihood of progression may be significantly greater among women with earlier presentation.

IntroductionHome Blood Pressure (HBP) measurement is widely spread to manage hypertensive disorder worldwide but, in obstetric field, HBP measurement is still not a standard method to manage pregnant induced hypertension (PIH). We collected the HBP in pregnant women and assessed the trend of HBP during pregnancy.Patients and MethodsFive hundred seventy one pregnant women were recruited to this study. The electric sphygmomanometer for home use was provided

69Abstracts for The 46th International Congress on Pathophysiology of Pregnancy

before 15 weeks of pregnancy. The HBP measurement was recommended to perform just after getting up and before sleep, three times in each measurement.The onset of PIH was observed in 51 women and data from these women were omitted. The HBP date from 520 women were analyzed.ResultsThe HBP in 10 weeks of pregnancy was 103.0 ± 10.1 / 61.3 ± 8.7mmHg (systolic pressure / diastolic pressure). The HBP in 20, 30, and 40 weeks of pregnancy was 103.6 ± 9.9 / 59.4 ± 8.4mmHg, 105.3 ± 10.5 / 60.7 ± 8.8mmHg, and 112.4 ± 10.5 / 66.8 ± 8.6mmHg (systolic pressure / diastolic pressure) respectively. The home systolic pressure rose up during pregnancy and decline of systolic pressure in the second trimester was not observed. The home diastolic pressure was observed to hit the bottom in 20 weeks of pregnancy and continue to rise up after the bottom. The pulse rate was maximized in the 32 weeks of pregnancy and decreased until delivery.No difference was observed in the home systolic pressure between getting up and before sleep. Otherwise, the home diastolic pressure was observed to 5 mmHg higher just after getting up than before sleep.DiscussionThe trend of pulse rate is considered to relate to the circulating plasma volume in pregnant women which is also maximized in the 32 weeks of pregnancy. The drop of blood pressure in the second trimester is observed only in home diastolic pressure. Through this result, the trend of home blood pressure during pregnancy might be different from the trend of office blood pressure.

Blood pressure measurement is the most important issue for diagnosis of hypertension. For hypertensive disorders during pregnancy, the measurement is also important. Blood pressure measurement is classified into conventional clinic blood pressure measurement and out-of-office blood pressure measurements. Out-of-office blood pressure measurements consists of ambulatory blood pressure measurement and home blood pressure measurement. They are strongly recommended for using for diagnosis and treatment of hypertension. Recent Guideline of Japanese Society of Hypertension recommended using home blood pressure measurement when home blood pressure and clinic blood pressure indicate different diagnosis criteria. Although this recommendation for hypertension is based on the several evidence from not only cross-sectional study, but also longitudinal observation study which observed long-time prognosis, there are little evidence of out-of-office blood pressure measurement for pregnant women.We have studied home and clinic blood pressure change during pregnancy among women who consented to measure their home blood pressure from early pregnancy to 1-month after delivery (the Babies and their parents’ longitudinal Observation in Suzuki memorial Hospital on Intrauterine period (BOSHI) study). In this workshop, some results from the BOSHI study will be presented.

Aim: To evaluate the screening performance of plasma level of soluble fms-like tyrosine kinase 1 (sFlt-1) /placental growth factor (PlGF) ratio or home blood pressure monitoring (HBPM) for predicting the occurrence of preeclampsia (PE).Methods: In the first study, using sFlt-1/PlGF ratio during 19-31 weeks determined by an automated electrochemiluminescence immunoassay, we developed prediction of imminent onset of PE with onset at < 4 weeks after blood sampling. In the second study, using the weeks at inflection point in HBPM, we developed prediction of PE.Results: In the first study, the onset threshold of the sFlt-1/PlGF ratio was determined using 25 women with PE. The imminent onset of PE was identified in 0.2% (2/1199) at 19–25 weeks and in 0.8% (6/798) at 26–31 weeks. The onset threshold of the sFlt-1/PlGF ratio at 19–25 weeks yielded sensitivity (SE) of 100% and specificity (SP) of 100%; the onset threshold of the sFlt-1/PlGF ratio at 26–31 weeks yielded SE of 83% and SP of 99.4%. In the second study, the inflection point was observed in 80% (12/15) of PE, and it occurred median 4 weeks before the onset. Using 30 normal pregnant women and 15 women with PE, the cutoff level of 30 weeks of the inflection point yielded SE of 53% and SP of 93%.Conclusion: The detection of the level of sFlt-1/PlGF ratio at 19-31 weeks or HBPM during the latter half of pregnancy period may be clinically useful for predicting the occurrence of PE.

W8-1. The occiput spine angle: a new sonographic index of fetal head defl exion during the fi rst stage of labor

Tullio GhiObstetrics and Gynaecology, S. Orsola Malpighi Hospital, Bologna, Italy

1) objectives: To assess sonographically the degree of fetal head defl exion during the 1st of labor and to evaluate the reproducibility of this parameter.2) methods: In a non consecutive series of women during the 1st stage of labor with the fetus in occiput anterior position, the angle between the occipital bone and the cervical spine of the fetus (occiput-spine angle or OSA) was measured by 2D ultrasound by operator A (Fig 1). The sonographic picture was stored in the archive of the machine and the measurement was repeated at distance by the same examiner and by a different one (operator B). The intra- and interobserver reproducibility of this measurement was assessed by means of intraclass correlation coeffi cient.3) results: Overall 33 women in the fi rst stage of labor were included in the study group. The OSA was measured at a mean cervical dilatation of 4.0 ± 0.9 cm and showed a mean value of 128.7 ± 12.5°. OSA measurements showed excellent intra- and interobserver agreement (intraobserver 0.87, 95% CI 0.75-0.93; interobserver 0.82, 95% CI 0.67-0.91).4) conclusions: In fetuses with occiput anterior position, the degree of fetal head defl exion during the 1st of labor may be reliably measured by transabdominal 2D ultrasound. A larger population is required in order to investigate if this new sonographic parameter has a correlation with labor outcome.

W8-2. The effectiveness of ultrasound examination to detect the antenatal viral infection in normal and preeclampsia complicated pregnancy

ObjectivePreeclampsia is a common pregnancy disorder that originates in the placenta and causes variable maternal and fetal problems. In the worst cases, it may threaten the survival of both mother and baby.There are different models for the pathogenesis of preeclampsia and the infl ammatory model is one of them because of growing body of evidence suggested for a causal link between maternal infection and preeclampsia. Maternal infection, including viral infection, are very important in the pathogenesis of preeclampsia.Also the intrauterine infection are one of the most frequent causes of perinatal mortality may account for as much as 20% of fetal and neonatal disease. A lot of pregnancies are complicated by clinically overt viral infectious illnesses and many more may be affected by silent viral infection.Any infection (bacterial or viral) is associated with a two fold higher risk of preeclampsia. The double impact of infection both to maternal and foetal status on both sides, directly and next indirectly - intensifying the grave alterations adding the preeclampsia, cause the different complications with increasing risk of maternal & foetal morbidity and mortality.

72 Abstracts for The 46th International Congress on Pathophysiology of Pregnancy

Preeclampsia/eclampsia is really one of these expected complications that needs as key aspect the efficient prenatal care for monitoring pregnancies. Ultrasonography is one of main diagnostic tools needed for prenatal care.The aim of study was to evaluate how useful is the ultrasound examination to detect the alterations specifically for the antenatal viral infection in normal and preeclampsia complicated pregnancy, also to predict the manifestation of preeclampsia in pregnant affected by intrauterine viral infection.Methods1. Screening ultrasound examination (USD) were performed in 2,577 clinically healthy pregnant in 2nd and 3rd trimester - group 12. Ultrasound examination were performed in untreated 78 pregnant in 2nd and 3rd trimester with intrauterine viral infection(IVI)

primary identified by biochemical markers - group 23. Ultrasound examination were performed in 35 pregnant in 2nd and 3rd trimester with clinically overt symptoms of preeclampsia - group 3Cross-correlation analysis was performed in these three groups and used special statistical methods.Results

Screening USD ( 2,577 pregnant- group 1 )specific changes in the fetus and placentadetermined in 37 pregnant (1.44 %)none determined in 2,540 pregnant (98.56%)persistence of infectiondetected 23 (62.0 % of 37 pregnant)none detected 14 (38.0 % of 37 pregnant)

Persistence of viral infection (78 pregnant with primary biochemically identified IVI - group 2)specific changes in the fetus and placentadetermined in 28 cases (35.8 %)none detemined in 50 cases (64.2 %)

Preeclampsia (35 pregnant - group 3)specific changes in the fetus and placentadetermined in 31 cases (88.6 %)none detemined in 4 cases (11.4 %)

ConclusionUltrasound scanning is capable to detect most of the grave alteration typical of fetal infection.Doppler studies can be used to study alterations in vascular flow that result from congenital infection.Ultrasound scanning is capable to predict the manifestation of preeclampsia in pregnant affected by intrauterine viral infection.The use of the routine ultrasound examination as a separate screening test to detect viral intrauterine infection has certain limitations and further biochemical tests are desirable.

W8-3. Uterine artery Doppler longitudinal changes and early-onset intrauterine growth restriction: a case-control study

Alessandra CurtiDepartment of Medicine and Surgery DIMEC–Division of Prenatal Medicine,

St. Orsola Malpighi Hospital, University of Bologna, Bologna, Italy

Objective: To evaluate the longitudinal changes in uterine artery Doppler pulsatility index (UtAPI) in pregnancies complicated by early-onset intrauterine growth restriction (IUGR).Method: This was a retrospective case–control study including 53 singleton pregnancies affected by IUGR at 20-28 weeks and confirmed at delivery (cases), matched for gestational age with 1000 controls. Measurement of UtAPI was taken every 4 weeks between 20 and 34 weeks of gestation. Multivariable analyses were used to estimate the UtAPI as a function of both gestational age and IUGR severity. Finally, bootstrapping technique was used to internally validate our models.Results: Regression line for IUGR cases having Log10 UtAPI as dependent variable was a function of both gestational age and IUGR. Also a significant interaction between the two predictors was found, showing a divergent pattern throughout pregnancy between cases and controls. In fact, at 20 weeks the UtAPI ratio between cases and controls was 1.84, but at 30 weeks it raised to 2.05. Finally, the birth weight was inversely correlated with the UtAPI values.Conclusion: We presented a reliable multivariable statistical model to evaluate the longitudinal changes of UtAPI values as a function of both gestational age and IUGR.

W8-4. First trimester prediction of ischemic placental disease

Alexandra Maternity Hospital, University of Athens, Greece

Ischemic placental disease (IPD) is a relatively new term that describes the poor placentation and vascular insufficiency of the placental unit in early pregnancy. IPD is characterized by various clinical manifestations of preeclampsia, intrauterine fetal growth restriction, and placental abruption. It seems that these three clinical conditions share a common underlying pathophysiology. That makes IPD the leading cause of iatrogenic preterm delivery ranging from the periviable to late preterm period. Increased risk of poor maternal and neonatal outcomes makes early prediction and prevention of IPD very important. Various serum and ultrasound markers have been used for the prediction and prevention of IPD during the second and third trimester of pregnancy. However it seems that prediction of IPD during the first trimester of pregnancy is of greater importance as it may help to the development of more effective prevention strategies. The current models for the prediction of IPD use a combination of maternal history and characteristics, mean maternal arterial blood pressure, maternal serum Pregnancy- Associated Plasma Protein-A (PAPP-A), mean maternal uterine arteries Pulsatility Index (UtA PI) and Placental Growth Factor (PIGF). These models provide low false positive rates ranging from 5 to 10%, and relatively high predictive rates of severe preeclampsia (95%) and Small for Gestational Age (SGA) fetuses prior to 34 weeks of gestation (55%). Administration of low dose aspirin or Low Molecular Weight Heparin, in early pregnancy, to those pregnant women identified as high risk, may be helpful in the prevention of IPD. Further larger scale studies are necessary.

W9-1. Preeclampsia complicated by other medical disorders

Sanjay GupteGupte Hospital & Centre for Research in Reproduction, Pune, India

Hypertension in pregnancy can be because of preeclampsia or it can also be due to chronic disease leading to hypertension. Such disorders can be vascular, endocrine, renal or of connective tissue origin. When these disorders are present; patient may often get superimposed. When this happens the pregnancy outcome defi nitely worsens. Hence it is important to diagnose these conditions early. Preferably diagnosis should be made preconceptionally & the management should start there & then. The preconceotional counseling & modifi cations of medication after proper assessment are vitally important for such patients & can make a difference in saving lives. Further on during pregnancy multidisciplinary approach is required to achieve reasonably acceptable outcome of pregnancy. Here we would like to present our experience with such cases of chronic hypertensive diseases which were further complicated with preeclampsia.

W9-2. Management of preeclampsia (PE) in Japan.

Taichi AkahoriDepartment of Obstetrics and Gynecology, Saitama Medical Center/ Saitama Medical University

Preeclampsia (PE) is a syndrome characterized by the onset of hypertension and proteinuria after 20 weeks of gestation. Dysgenesis of placentation in early pregnancy may result in relative placental hypoperfusion, which leads to release of antiangiogenic factors that alter maternal systemic endothelial function and induces symptoms of PE.In the management of PE, it is important to control blood pressure (BP) at appropriate level to prevent maternal and fetal complications. It is assumed that risk of eclampsia and cerebrovascular disorder increases when systolic BP exceeds 180mmHg, or diastolic BP exceeds 120mmHg. However, excessive suppression of BP may cause an iatrogenic dysfunction of feto-placental circulation. Although there is no established evidence for the extent of BP reduction, it is recommended to decrease 15% of mean arterial BP or to suppress severe hypertension to mild level.In Japan, hydralazine and methyldopa have been widely used as antihypertensive agents for PE, in spite of their insufficient hypotensive effect, just because sufficient experience of administration to hypertensive pregnant women. Only intravenous nicardipine (calcium-channel blocker) had been approved for PE patients with informed consent. It was just two years ago that nifedipine and labetarol were approved for pregnant women, so there are few reports in Japan for Ca blockades or α-β blockades comparing with foreign countries. We review our challenge and outcome in the management of PE with before-mentioned limitation in Japan.

Drug therapy for pregnancy induced hypertension (PIH) should be started at a blood pressure (BP) of severe hypertension ( ≥ 160/110mmHg). When selecting antihypertensive drugs for hypertension during pregnancy, methyldopa, hydralazine, labetalol or nifedipine after week 20 of pregnancy should be selected as a first-choice drug. When systolic BP is ≥ 180mmHg or diastolic BP is ≥ 120mmHg was shown in pregnant or postpartum women, antihypertensive drugs for intravenous injection should be started under a diagnosis of hypertensive emergency. Two representative hypotensors, labetalol and nicardipine will be introduced in this work shop.Labetalol, αβ-blocker has been be useful for managing BP in pregnant women complicated by severe hypertension in world wide. It can also be used by revise of the package inserts since June 2011 in Japan.Thirty four pregnant women shown severe hypertension (16 preeclampsia; PE and 18 gestational hypertension; GH) were given oral labetalol 300-400mg daily. Fifteen were shown to be decrease in BP, more than 10% (effective), while 19 were less than 10% (ineffective) on 3rd day after administration. It was significant effective in GH (11/18) compared with that in PE (4/16, P = 0.02). The clinical symptoms disappeared in both group. The unfavorable changes in fetal heart rates was seen in 3 (1 for effective and 2 for ineffective).Postpartum women after cesarean section showed systolic BP ≥ 160mmHg, including 9 women complicated by hypertensive emergency were given by intravenous administration of nicardipine at 1-6mg/hr. Their BP subsequently could be stabilized under 160mmHg.

Since 1996, I have been studying the pathophysiology of preeclampsia, focusing on the vascular endothelial function seen in preeclampsia in Department of Pharmacology in NCU. I found that reduction of nitric oxide action might be not due to reduced production but reduced action of NO-cGMP pathway (J Physiol 2000), while a decrease in prostacyclin production was seen in the resistance artery obtained from preeclamptic women. (J Physiol 2002). Furthermore, it was found that administration of L-arginine plus folic acids could improve the reduced of NO action seen in animal model (Br J Pharmacol. 2005). Similarly, the administration in high risk women might prevent onset of preeclampsia due to improvement of the endothelial dysfunction.

W9-4. A novel pharmacotherapy of preeclampsia

Nobuyuki TakahashiTohoku University Graduate School of Pharmaceutical Sciences, Sendai, Japan

Pre-eclampsia (PE) is an important cause of maternal and fetal deaths due to pregnancy. The only definitive treatment to save their lives is to deliver the baby and the placenta, which results in a premature baby. Anti-hypertensives acceptable for use during pregnancy help control maternal blood pressure in PE, but they often reduce the blood supply to the placenta and the baby, leading to fetal growth restriction. This is most likely because these anti-hypertensives do not correct abnormalities specific to PE (which include high plasma levels of placentally-derived sFlt-1 and endotheliosis). We and other investigators have demonstrated that endothelin (ET-1) plays an important role in the pathogenesis of PE, and that antagonists of the endothelin type A receptor (ETAR) greatly ameliorate the PE-like condition that develops in rodents with experimentally induced excess sFlt-1. Unfortunately, ETAR antagonists are teratogenic and consequently unacceptable for use in treating PE. However, nicotinamide, a naturally occurring widely used amide of vitamin B3, is a potential non-teratogenic alternative because it relaxes blood vessels constricted with endothelin. The effects of nicotinamide on a PE-like condition in mice will be discussed.

W9-5. Increased placental expression of cannabinoid receptor 1 in preeclampsia

Attila MolvarecFirst Department of Obstetrics and Gynecology, Semmelweis University, Budapest, Hungary

Objective: The endocannabinoid system plays a key role in female reproduction, including implantation, decidualization and placentation. In the present study, we aimed to analyze cannabinoid receptor 1 (CB1), CB2 and fatty acid amid hydrolase (FAAH) expressions and localization in normal and preeclamptic placenta, in order to determine whether aberrant endocannabinoid activity is related to preeclampsia.Methods: Eighteen preeclamptic patients and 18 normotensive, healthy pregnant women with uncomplicated pregnancies were involved in our case-control study. We determined CB1, CB2 and FAAH expressions by Western immunoblotting and immunohistochemistry in placental samples collected directly after Cesarean section.Results: CB1 expression measured by Western immunoblotting was significantly higher in preeclamptic placenta, and these findings were confirmed by immunohistochemistry. CB1 immunoreactivity was markedly stronger in syncytiotrophoblasts, the mesenchymal core, decidua, villous capillary endothelial and smooth muscle cells, as well as in the amnion in preeclamptic samples compared to normal pregnancies. However, we did not find significant differences between preeclamptic and normal placenta in terms of CB2 and FAAH expressions and immunoreactivity.Conclusions: We observed markedly higher expression of CB1 protein in preeclamptic placental tissue. Increased CB1 expression might cause abnormal decidualization and impair trophoblast invasion, thus being involved in the pathogenesis of preeclampsia. As CB1 activation can induce endothelial dysfunction and enhance vascular inflammation, the strong CB1 immunoreaction in vascular endothelial and smooth muscle cells suggests that CB1 may contribute to the development of atherosis in the placental villi shown earlier in preeclampsia. While the detailed pathogenesis of preeclampsia is still unclear, the endocannabinoid system seems to play a role in the development of the disease.

Recent years have witnessed some progress in the studies of the general characteristics of cell-free DNA, such as its concentration, extent of molecular weight, origin and existing forms, as well as in its clinical application. Biomarkers can be employed for screening for fetal genetic disorders, identifying individuals at sufficiently high risk for a confirmatory invasive procedure. Identification of cell-free fetal nucleic acids (DNA and RNA) in maternal plasma and the recognition that they represent a useful source of fetal genetic material for prenatal diagnosis has led to intensive efforts to develop non-invasive prenatal testing. This presentation summarizes the general characteristics and biological functions of cell-free DNA, recent developments in the field of non-invasive prenatal diagnosis through the use of cell-free fetal nucleic acids in maternal circulation during pregnancy and provides an overview of the possibilities for future clinical applications.

W10-1. Arrested lineage progression of oligodendrocytes with minor damage in the corticospinal tracts in developmental white matter injury model rat

Hideki HidaDept. Neurophysiol. & Brain Sci., Nagoya City Univ Grad Sch Med Sci, Nagoya 467-8601, Japan

Developmental white matter injury (DWMI) caused by hypoxia-ischemia (H-I) is associated with permanent neurodevelopmental disabilities such as motor and cognitive defi cits in preterm infants. As selective vulnerability of oligodendrocyte (OL) progenitor cells (OPCs) was reported in some case of DWMI, we made a DWMI model rat that was made by H-I (right common carotid artery occlusion followed 6% hypoxia for 1 hour) at P3. Impaired motor function especially in the hindlimb was shown in this model. To investigate pathological relevance to functional defi cits in this model, we investigated the pattern of cellular degeneration, counted the number of OL lineage cells and checked neuron damage after H-I. Active-caspase3/NeuN double-positive apoptotic neurons were not detected in the cortex. Detection of OL lineage markers revealed that NG2 positive cells increased in the ipsilateral WM at 2 day and PDGFRα positive cells increased at 7 day after H-I. Mature APC-positive OL decreased by 84 ± 2.45 % (n = 4) at 6 month later. Data suggest that cell death in the corticospinal neurons were not directly induced by H-I but arrested OL lineage progression with indirect minor damage of the neurons were induced in DWMI model rat. In addition, we will report our challenge in cell transplantation of mouse iPS cell-derived OPCs to DWMI model rat.

W10-2. Current perspectives in hypoxic-ischemic encephalopathy in Japan

Masahiro HayakawaCenter for Maternal-Neonatal Care, Nagoya University Hospital

Hypoxic ischemic encephalopathy (HIE) is one of the most critical pathologic conditions in neonatal medicine. Despite HIE is important disease, there are few reports of the incidence of HIE. This may be due to the fact that establishing a diagnosis of HIE may be challenging because infants may present with non-specific symptoms and HIE is not always caused by a sentinel event. Further, in some cases, an obvious hypoxic-ischemic event may have not been apparent during the intrapartum period or immediately after birth. Because of the diagnostic difficulty, neonatologists and obstetricians are not always able to recognize brain insult in infants who suffer partial asphyxia at birth. Therefore, the incidence of HIE might be underestimated.Hypoxic ischemic brain injury secondary to birth asphyxia can result in the development of cerebral palsy. Some publications have reported predictive factors for neurodevelopmental outcome in infants with HIE. Electroencephalography (EEG), magnetic resonance imaging (MRI), and laboratory data at birth are useful tools for predicting outcome based on neonatal risk factors. Whereas maternal and antenatal factors may foretell the development of HIE, these variables do not predict mortality or neurodevelopmental outcome.This lecture highlights current perspectives in HIE in Japan based on nationwide surveillance.

W10-3. Trends in perinatal brain damage in our population-based study

Hiroshi SameshimaProfessor and Chairman, Department of Obstetrics and Gynecology, University of Miyazaki

Objective: Trends in cerebral palsy was investigated in a regional population-based study (PBS) in southern Japan where the perinatal mortality has been the world lowest.Materials and methods: From 1998, we performed a PBS on perinatal deaths and neonatal brain damage in Miyazaki District in which we have 10,000 deliveries annually. High risk infants were reported by 7 regional secondary centers on a voluntary basis, which presumably covers 90-95% of handicapped infants according to our previous study. Two consecutive 5-year periods (2001-2005, 2006-2010) were compared.Results: Each period had 51,000 deliveries. Fetal deaths decreased (157 to 136), so did neonatal deaths (79 to 47), infantile deaths (163 to 119) and brain-damaged infants (126 to 88), where all changes reached statistically significant (Chi square test, p < .05). Among the infants with brain damage, term infants decreased while preterm infants (26 to 36 weeks of gestation) increased. The most contributing factors to these changes were a decrease in asphyxia at term and an increase in PVL at preterm. However, unknown causes or multiple causes were still existed.Conclusion: Our regional PBS reveals that the perinatal mortality and infantile mortality has decreased significantly with a significant decrease in the incidence of brain damage. This trend is true with term infants, but not with preterm infants.

W10-4. The Japan obstetric compensation system for cerebral palsy

Takashi OkaiDirector, Imperial Gift Foundation, Maternal and Child Health Center Aiiku Hospital

It is usually difficult to determine malpractice in cases of medical accidents during delivery, and these cases are often contended in court. The frequency of such disputes is one of the reasons for the shortage in Obstetricians.In order to maintain an environment that can, in part, provide Obstetric care without worry, we have launched the Japan Obstetric Compensation System for Cerebral Palsy (JOCSCP).Basic concept of JOCSCP includes two parts, those are “compensation” and “analysis of causes & measures to present future cases”. Persons eligible for compensation are children with severe cerebral palsy related to brain injuries during delivery. For nursing care expenses, total monetary compensation of 30 million yen is provided to the families of CP babies in the installment way.As of May 2013, 501 cases have been accepted and cause analyses completed in 319 cases. The most frequent cause of CP was abruption placenta which covered about 25% of all cases and the second was cord compression, but we found other various factors related to CP.Both medical provide side and patient side showed the opinion that they consented the reports from cause analysis committee in more than 70% of the cases.After launching JOCSCP, the litigation rate has been deceased.The detailed date will be presented in the presentation of the congress.

W10-5. Analyses of 39 cases of cerebral palsy caused by placental abruption on the Japan obstetric compensation system for cerebral palsy

Keiya FujimoriDepartment of Obstetrics and Gynecology, School of Medicine, Fukushima Medical University

Placental abruption was the most common cause of cerebral palsy in 128 patients enrolled between January 2009 and June 2012 in the Japan Obstetric Compensation System for Cerebral Palsy, accounting for 39 cases. We analyzed these 39 cases.For the risk factors profile, 77% of these women were multiparous, 17% were smokers, and 10% were with preeclampsia, however no recurrent case was found.Two thirds of the patients developed placental abruption at home. One third of the patients were transferred to a tertiary hospital after diagnosis.The initial symptoms of the patients were abdominal pain in 62%, vaginal bleeding in 13%, and loss of fetal movement in 21%. Preterm labor was originally diagnosed in 44% and β2-stimulants were administered.Ultrasonography was performed in two thirds of the cases, of which 40% had retroplacental hematoma, 24% had placental thickening, and 28% had no abnormal findings. More than half of the patients had abnormal fetal heart rate, mostly bradycardia, on admission. Medians of the birth week and neonatal weight were 37.3 weeks and 2,522 g, respectively. The median decision-to-delivery interval was 39 minutes. Delivery in 85% of the cases was by cesarean section. Umbilical blood gas analysis was performed in 77%, and pH was less than 7.0 in all cases except one.The education of pregnant women on the initial symptoms of placental abruption (abdominal pain, vaginal bleeding, loss of fetal movement), recommending earlier consultations with the symptoms, and diagnosis by using cardiotocography and ultrasonography are important factors in decreasing cerebral palsy resulting from placental abruption.

W11-1. What is the problem with echo screening for congenital heart disease?

Ryu MatsuokaDept. of Obstetrics and Gynecology, Showa University School of Medicine

Congenital Heart disease (CHD) is most common disease up to 1% with newborn baby, and has also much variation of disease and in severity. Therefor CHD has a big impact on the prognosis of newborn baby. It is clear fetal diagnosis of CHD is important. But it is not so easy. Objectives: The purpose of this study is to identify and remedy the problems of fetal cardiac scan and to explore an improvement in it. Methods: The clinical course and diagnosis of CHD except karyotype disorder in our department in 2000 - 2010 were reviewed retrospectively. All pregnant women undergo thorough ultrasound examination for fetus at 18~19 and 30 weeks of gestation or at the fi rst time of visit. The scan was performed according to our check up list.Result: The incident of CHD was 1.0% (111cases) in all deliveries (11,072 cases). The prenatal diagnosis rate of CHD was 47.7% (53/111). There were 31 in 45 cases, excludes fetal arrhythmia and small VSD (20 cases were referrals case). 14 cases could not be detected (5 pulmonary artery stenosis, 3 total anomalous pulmonary venous return, 2 tetralogy of Fallot, 1 corrected transposition of great arteries, 1disease transection of the aorta, 1 mitral stenosis, 1 pulmonary artery atresia). Seven cases of 14 had cyanosis after birth. Conclusion: CHD with obvious morphological defect can be detected regardless of special technic or way of ultrasound exam. However, only a screening test with 4CV ∙ 3VV is insuffi cient, in order to improve the detection rate of CHD. So, we need scan with building cross-section must be based on precise anatomical knowledge.

W11-2. Fetal echocardiography: cardiac function

Yuka YamamotoDepartment of Obstetrics and Gynecology, Juntendo University Faculty of Medicine

At fetal stage, the ventricular wall has original stiffness due to the immature myocardium with less calcium storage and random cell arrangement. In utero, right ventricle works more than the left which is equal to 60% of total combined cardiac output (CCO) in the right. With gestation, CCO increases exponentially from 210ml/min at 20 weeks to 1900ml/min at 38 weeks. Due to this dramatic change of fetal circulation before birth, it is important to know how to evaluate the fetal cardiac function with the limited tools.The simple way to evaluate fetal cardiac function is a two dimentional ultrasound such as cardiac thoracic ratio and m-mode to calculate the ejection fraction. Doppler assessments include infl ow Doppler (Tei index, isovolemic relaxation time (IVRT) and isovolemic contraction time (ICT)) and systemic venous Doppler (ductus venosus, inferior vena cava and umbilical vein). Indeed, we calculate the CCO in the fetus. Furthermore, tissue Doppler imaging and velocity vector imaging (VVI) also apply to evaluate the fetal cardiac function.At fi rst trimester, the stiffness of fetal heart is obvious with monophasic infl ow and longer IVRT& ICT. The atrial contraction is important and it seems to contribute the additional CCO. Impaired atrial contraction such as Ebstein’s anomaly is critical for fetuses to survive even fetal stage. Fetal echocardiogram can provide additional information to manage complicated fetuses as well as help to understand natural history of fetal circulation.

Junichi HasegawaDepartment of Obstetrics and Gynecology, Showa University School of Medicine, Tokyo, Japan

Objective: To clarify the usability of ultrasound screening for predicting non-reassuring fetal status (NRFS) during labor.Methods: Prospective cohort study was conducted between 2012 and 2013. Ultrasound screening of placenta and umbilical cord abnormalities using check list were attempted at 36 weeks’ gestation. Subjects who were taken this ultrasound screening and not planned elective cesarean section (CS) were divided into three levels of groups according to the risk of NRFS. After delivery, frequencies of NRFS and emergency CS rate were compared among these risk groups. High risk was defined in cases with velamentous, marginal cord insertion on the lower uterus, three or more nuchal cords and/or hyper-coiled cord. Middle risk was defined in cases with the other velamentous insertion, moderate fetal growth restriction, twice nuchal cords, and/or single umbilical artery. The others were defined as low risk.Results: After exclusion of 111 cases of elective CS, 34 cases of high, 45 cases of middle and 600 cases of low risk were analyzed. NRFS was diagnosed in 17.6% (6/34) of high risk, 11.1%* (5/45) of middle risk and 6.2% (37/600) of low risk, respectively. Emergency CS was performed in 8.8% (3/34) of high risk, 4.4% (2/45) of middle risk, and 1.0% (6/600) of low risk, respectively (*p < 0.05 compared to low risk).Conclusion: Antenatal ultrasound screening of placental and umbilical cord abnormalities could identify cases of high risk delivery.

W11-4. Fetal bone dysplasia and analysis of pathophysiological mechanisms

Seiji TsutsumiDepartment of Obstetrics and Gynecology, Yamagata University, Faculty of Medicine

Fetal bone dysplasias are rare disorders. These conditions have been estimated to affect one in 100,000 newborns. In the present situation, no cure is known for almost of them, and it is not necessarily that the precise diagnosis contributes its treatment or improvement of prognosis. However, because they include some groups with poor life prognosis, it is clinically meaningful to diagnose precisely, predict neonatal prognosis, and prepare for perinatal management. For obstetrician, it is particularly important to manage the cases which comprise conditions that usually lead to death in utero, at or shortly after birth. For example, thanatopholic dysplasia is one of the neonatally lethal osteochondrodysplasia due to hypoplastic lung, but some patients with thanatophoic dysplasia have been kept alive into late childhood with continued intensive care. Osteogenesis imperfecta is increased lethality depending on sub-type.At our facility, we examined 13 fetal bone dysplasias for the past eight years. 10 cases were diagnosed prenatally by images of ultrasonography and/or X-ray 3-dimentional computed tomography. Furthermore, the causative gene mutations were identified in four cases of them. Under precise diagnoses using graphical imaging and genetic analysis, we could provide appropriate support including genetic counseling.
