RESUMO

In eutherians, the placenta plays a critical role in the uptake, storage, and metabolism of lipids. These processes govern the availability of fatty acids to the developing fetus, where inadequate supply has been associated with substandard fetal growth. Whereas lipid droplets are essential for the storage of neutral lipids in the placenta and many other tissues, the processes that regulate placental lipid droplet lipolysis remain largely unknown. To assess the role of triglyceride lipases and their cofactors in determining placental lipid droplet and lipid accumulation, we assessed the role of patatin like phospholipase domain containing 2 (PNPLA2) and comparative gene identification-58 (CGI58) in lipid droplet dynamics in the human and mouse placenta. While both proteins are expressed in the placenta, the absence of CGI58, not PNPLA2, markedly increased placental lipid and lipid droplet accumulation. These changes were reversed upon restoration of CGI58 levels selectively in the CGI58-deficient mouse placenta. Using co-immunoprecipitation, we found that, in addition to PNPLA2, PNPLA9 interacts with CGI58. PNPLA9 was dispensable for lipolysis in the mouse placenta yet contributed to lipolysis in human placental trophoblasts. Our findings establish a crucial role for CGI58 in placental lipid droplet dynamics and, by extension, in nutrient supply to the developing fetus.

RESUMO

AIM: To evaluate pregnancy outcome and complications in subsequent pregnancies after severe post-partum hemorrhage (PPH) between women with and without a history of uterine artery embolization (UAE). METHODS: Women who had a history of severe PPH, and delivered newborns at ≥22 gestational weeks in subsequent pregnancies were enrolled. Severe PPH was defined as blood loss volume of more than 2000 mL. RESULTS: The blood loss volume (median 1581 mL) in women with UAE (n = 14) was significantly more than that in women without UAE (median 1021 mL, n = 32, P < 0.01), and the recurrence rate of severe PPH in women with UAE (n = 5, 35.7%) was significantly higher than that in women without UAE (n = 3, 9.4%, P < 0.05). There were no significant differences in frequencies of premature delivery, hypertensive disorders of pregnancy, fetal growth restriction, or placenta previa/low lying placenta. Of 14 women with UAE, 7 (50.0%) had abnormally invasive placenta, whereas of 32 women without UAE, none had abnormally invasive placenta. CONCLUSION: Subsequent pregnancies after UAE for severe PPH had high risks for recurrence of severe PPH.

RESUMO

BACKGROUND: The aim of this prospective cohort study was to determine clinical factors associated with the occurrence of congenital cytomegalovirus infection (cCMV) in pregnant women. METHODS: Between March 2009 and November 2017, newborns born at a primary maternity hospital received polymerase chain reaction (PCR) analyses for CMV DNA in their urine with informed consent of the mothers at a low risk. Clinical data, including age, gravidity, parity, body mass index, occupation, maternal fever/flulike symptoms, pregnancy complications, gestational weeks at delivery, birth weight, and automated auditory brainstem response, were collected. Logistic regression analyses were performed to determine clinical factors associated with cCMV. RESULTS: cCMV was diagnosed by positive PCR results of neonatal urine in 9 of 4125 pregnancies. Univariate and multivariable analyses revealed that the presence of fever/flulike symptoms (odds ratio [OR], 17.9; 95% confidence interval [CI], 3.7-86.7; P < .001) and threatened miscarriage/premature labor in the second trimester (OR, 6.0; 95% CI, 1.6-22.8; P < .01) were independent clinical factors associated with cCMV. Maternal fever/flulike symptoms or threatened miscarriage/premature labor in the second trimester had 100% sensitivity, 53.2% specificity, and a maximum Youden index of .85. CONCLUSIONS: This cohort study for the first time demonstrated that these clinical factors of pregnant women and newborns were associated with the occurrence of cCMV. This is useful information for targeted screening to assess risks of cCMV in low-risk mothers, irrespective of primary or nonprimary CMV infection.

RESUMO

Congenital syphilis may lead to severe sequelae in affected infants. The prevalence of syphilis in women of childbearing age has increased worldwide. From 2015 to 2018, we encountered eight pregnant women with syphilis including six with late latent and two with early latent syphilis. Seven pregnant women with syphilis received antibiotic therapies of oral amoxicillin, intravenous penicillin G, or the both. The syphilotherapies in four cases were considered effective, because rapid plasma reagin titers decreased. None of the seven pregnant women who received syphilotherapies had congenital syphilis. The remaining one woman who did not undergo a maternity checkup or syphilotherapy delivered a stillbirth with congenital syphilis at 29 gestational weeks.

RESUMO

Antibodies against fetal platelet alloantigens in maternal blood cause neonatal alloimmune thrombocytopenia (NAIT). We encountered four newborns with NAIT from three women. A woman carried anti-human platelet antigen (HPA)-1a antibody, and vaginally delivered a newborn who had subarachnoid hemorrhage and platelet transfusions. She delivered the second newborn by a cesarean section who had no symptom. The second woman carried anti-human leukocyte antigen-A2 antibody and vaginally delivered a newborn who had no symptom. The third woman with a history of recurrent pregnancy losses carried anti-HPA-4b antibody, and delivered a newborn by a cesarean section who received platelet transfusions and immunoglobulin infusions. Antiplatelet antibody screening may be helpful in women who have a history of blood transfusion, or previous neonates with thrombocytopenia or intracranial hemorrhage.

RESUMO

The aim of this prospective cohort study was to evaluate clinical factors associated with pregnancy outcomes in women with recurrent pregnancy loss (RPL). Women with a history of two or more pregnancy losses underwent workups for clinical factors of RPL and their pregnancies were followed-up with informed consent. Two hundred eleven (81.5%) of 259 women with RPL became pregnant. The multivariable analyses demonstrated that age (p < .01, OR 0.9, 95%CI 0.97-0.83), uterine abnormality (p < .05, OR 0.3, 95%CI 0.11-0.8), and protein C (PC) deficiency (p < .01, OR 0.14, 95%CI 0.03-0.6) were independent factors for becoming pregnancy in women with RPL. The number of previous pregnancy loss (p < .01, OR 0.57, 95%CI 0.43-0.75) and natural killer (NK) cell activity ≥33% (p < .01, OR 0.31, 95%CI 0.13-0.73) were independent factors for live birth in the subsequent pregnancy. Advanced age, the presence of uterine abnormality, and PC deficiency were risk factors for reduced pregnancy rate in women with RPL. Increased number of previous pregnancy loss and high NK cell activity were risk factors for miscarriage in the subsequent pregnancy. These results involve important information and are helpful for clinical practitioners.

RESUMO

The aims of this study were to assess the effect of maternal screening for hepatitis B (HB) virus and a perinatal prevention program of mother-to-child transmission, and to identify clinical characteristics and findings associated with HB exacerbation during pregnancy. This prospective cohort study enrolled 3796 pregnant women and their neonates with informed consent. Pregnant women underwent maternal universal screening for HBs antigen (Ag) in the first trimester. If HBs Ag was positive, serum levels of HBe Ag, alanine transaminase (AST), aspartate aminotransferase (ALT), and HB virus (HBV) DNA were measured. All neonates delivered from HBs Ag-positive women were given HB immune globulin and HB vaccine based on the guidelines of the perinatal prevention program. Of the 3796 pregnant women, 40 (1.05%) tested positive for HBs Ag. Three (7.5%) of the 40 HBs Ag-positive women experienced exacerbation of HBV infection during pregnancy. Serum levels of AST (median 776 vs. 22 mIU/ml, p < 0.01), ALT (median 325 vs. 15 mIU/ml, p < 0.01), and HBV-DNA (median 9.1 vs. 5.4 log copies/ml, p < 0.05), and frequencies of HBe Ag-positive (100% vs. 29.7%, p < 0.05) and symptoms of itching or general fatigue (66.7% vs. 0%, p < 0.01) in three women with exacerbation of HBV infection were significantly higher than those in 37 women without exacerbation. There was no case of mother-to-child transmission, suggesting the perinatal HBV prevention program was effective. Levels of HBe Ag, liver enzymes, and HBV-DNA as well as symptoms of itching and general fatigue should be carefully monitored for HBs Ag-positive women during pregnancy and the postpartum period.

RESUMO

Primary infection with Toxoplasma gondii (T. gondii) during pregnancy may cause congenital infection of the infant. This study evaluated whether screening using IgG avidity and multiplex-nested polymerase chain reaction (PCR) methods was effective for detecting a high-risk pregnancy for congenital T. gondii infection. In a prospective cohort study serum T. gondii IgG avidity was measured in 469 pregnant women who had a positive test for T. gondii antibody plus a positive or equivocal test for IgM. Multiplex-nested PCR for T. gondii DNA on amniotic fluid, maternal blood, and neonatal blood was performed with informed consent. Low (<30%), borderline (30-35%), and high (>35%) IgG avidity indices were found in 104 (22.2%), 30 (6.4%), and 305 (71.4%), respectively. A total of 12 cases had a positive PCR test for amniotic fluids of the prenatal amniocentesis or at birth, or neonatal blood. Seven of the 12 cases were diagnosed as having congenital T. gondii infection, and they had low IgG avidity indices. Congenital T. gondii infection screening using of IgG avidity and multiplex-nested PCR methods for pregnant women with a positive test for T. gondii antibody plus a positive or equivocal test for T. gondii IgM was useful for detecting a high-risk pregnancy and diagnosing congenital T. gondii infection.

RESUMO

INTRODUCTION: Cytomegalovirus (CMV) infection is the most common cause of congenital viral infections in humans. The unusual structure of the placenta plays a pivotal role in CMV transmission from mothers to fetuses. The aim of this study was to evaluate the histopathological findings of placentas with congenital CMV infections. METHODS: We obtained placental specimens from 35 women who had newborns with congenital CMV infections. Placental specimens, extraplacental membranes, and umbilical cords were stained with hematoxylin and eosin, and subjected to immunohistochemical analysis. We evaluated the localization of CMV-infected cells and other histological parameters. RESULTS: Thirty (86%) of the 35 placentas tested positive for CMV-infected cell proteins by immunohistochemistry. A majority of CMV-positive cells were present in fibroblasts and endothelial cells in the villi. The number of CMV-infected cells was inversely correlated to gestational age at delivery. The frequency of chronic villitis (65% vs. 11%; p < 0.01) and changes of the villi (38% vs. 0%; p < 0.05) in the placentas from mothers with symptomatic congenital CMV infections was higher than those observed in samples from mothers with asymptomatic congenital infections. The frequency of changes of the decidua (43% vs. 5%; p < 0.01) in the placentas from mothers with non-primary CMV infections was higher than those from mothers with primary infections. DISCUSSION: Chronic villitis and changes of the villi were associated with symptomatic congenital CMV infections. The changes of the decidua were associated with congenital CMV infections, in mothers with non-primary CMV infections.

RESUMO

Trophoblast hypoxia and injury, key components of placental dysfunction, are associated with fetal growth restriction and other complications of pregnancy. Accumulation of lipid droplets has been found in hypoxic nonplacental cells. Unique to pregnancy, lipid accumulation in the placenta might perturb lipid transport to the fetus. We tested the hypothesis that hypoxia leads to accumulation of lipid droplets in human trophoblasts and that trophoblastic PLIN proteins play a key role in this process. We found that hypoxia promotes the accumulation of lipid droplets in primary human trophoblasts. A similar accretion of lipid droplets was found in placental villi in vivo from pregnancies complicated by fetal growth restriction. In both situations, these changes were associated with an increased level of cellular triglycerides. Exposure of trophoblasts to hypoxia led to reduced fatty acid efflux and oxidation with no change in fatty acid uptake or synthesis. We further found that hypoxia markedly stimulated PLIN2 mRNA synthesis and protein expression, which colocalized to lipid droplets. Knockdown of PLIN2, but not PLIN3, enhanced trophoblast apoptotic death, and overexpression of PLIN2 promoted cell viability. Collectively, our data indicate that hypoxia enhances trophoblastic lipid retention in the form of lipid droplets and that PLIN2 plays a key role in this process and in trophoblast defense against apoptotic death. These findings also imply that this protective mechanism may lead to diminished trafficking of lipids to the developing fetus.

RESUMO

Congenital complete atrioventricular block (CCAVB) is a condition in which the atria and ventricles beat independently of each other. CCAVB cases require permanent pacemaker implantation until adulthood. Nevertheless, consensus regarding postnatal medical therapy for bradycardia has not been reached. Here we report the case of a newborn with CCAVB, whose intractable bradycardia was successfully treated with transdermal tulobuterol. Tulobuterol is a selective ß2-adrenoceptor agonist, widely used safely as bronchodilator in children. It also has positive inotropic and chronotropic effect via ß1-adrenoceptors. We believe the tulobuterol patch can be used as an optional therapy for CCAVB where pacemaker implantation is not available.

RESUMO

The aim of this nested case-control study was to evaluate clinical factors associated with the occurrence of congenital cytomegalovirus (CMV) infection in pregnant women with non-primary CMV infection. In a cohort study of CMV screening for 2193 pregnant women and their newborns, seven newborns with congenital CMV infection were identified among 1287 pregnant women with non-primary CMV infection that was defined as negative IgM and positive IgG with IgG avidity index >45%. In the 1287 women with non-primary CMV infection, clinical findings and complications were compared between pregnancies with and without congenital CMV infection. Clinical factors associated with the occurrence of congenital CMV infection were evaluated. The birth weight of newborns with congenital CMV infection was less than that of newborns without congenital infection (p < 0.05). Univariate logistic regression analyses demonstrated that threatened premature delivery (OR 10.6, 95%CI 2.0-55.0; p < 0.01) and multiple pregnancy (OR 7.1, 95%CI 1.4-37.4; p < 0.05) were associated with congenital infection. Multivariable logistic regression analyses demonstrated that threatened premature delivery (OR 8.4, 95%CI 1.5-48.1; p < 0.05) was a single risk factor for congenital CMV infection in pregnant women with non-primary CMV infection. This study revealed for the first time that threatened premature delivery was associated with the occurrence of congenital CMV infection in pregnant women with non-primary CMV infection, the pathophysiology of which may be closely associated with CMV reactivation during pregnancy.

RESUMO

PURPOSE: This study aimed to assess the efficacy of high-dose i.v. immunoglobulin (HIVIg) therapy in pregnant women with antiphospholipid syndrome (APS) secondary to systemic lupus erythematosus with a history of pregnancy failure, despite receiving low-dose aspirin plus unfractionated heparin therapy, of which condition being designated as "aspirin-heparin-resistant APS" (AHRAPS). METHODS: The HIVIg therapy (20 g/d, 5 days) was performed for the pregnancies of five women with AHRAPS. RESULTS: Five of the eight pregnancies ended in live births. The gestational ages of delivery in four of the five pregnancies were extended, compared with previous pregnancies. The HIVIg therapy was considered to be successful for these four pregnancies. Excluding one pregnancy that ended in miscarriage with an abnormal chromosome karyotype of the villi, the HIVIg therapy was considered to be successful in four (57.1%) of the seven pregnancies of the women with AHRAPS. Although all the live newborns were prematurely delivered, no adverse effect of the HIVIg therapy was observed. CONCLUSIONS: The HIVIg therapy might be beneficial as an immune modifier for pregnant women with AHRAPS. However, the precise indication of which women with AHRAPS who should receive HIVIg therapy remains unknown.

RESUMO

PURPOSE: To justify a classification system for angiographic images of uterine artery embolization (UAE) for postpartum hemorrhage (PPH) and identify new risk factors associated with failed embolization. MATERIALS AND METHODS: A retrospective analysis of 63 consecutive patients who underwent UAE for severe PPH was performed. Uterine artery angiography (UA) before embolization was classified into two types: type 1 was defined as complete staining and type 2 was defined as partial staining of the uterine arteries. The clinical outcome, UA classification, and other possible factors previously reported were evaluated. Univariate and multivariate analyses were performed to determine the factors related to clinical outcomes. RESULTS: Sixty-three patients were enrolled (type 1, 22; type 2, 41). The clinical success rates of the primary UAE session were 90.9% (20/22) for type 1 and 61.0% (25/41) for type 2 (p = 0.018). Univariate and multivariate analyses demonstrated that the only UA classification was significantly associated with primary UAE failure (p = 0.033). CONCLUSIONS: The UA classification is an independent predictive factor of the clinical success rate of the primary UAE session for PPH; thus, it is an intuitive and optimal predictor for interventional radiologists to decide whether additional therapy is necessary.

RESUMO

INTRODUCTION: Placenta previa (PP) is one of the most significant risk factors for adherent placenta (AP). The aim of this study was to evaluate the diagnostic efficacy of a novel scoring system for predicting AP in pregnant women with PP. METHODS: This prospective cohort study enrolled 175 women with PP. The placenta previa with adherent placenta score (PPAP score) is composed of 2 categories: (1) past history of cesarean section (CS), surgical abortion, and/or uterine surgery; and (2) ultrasonography and magnetic resonance imaging findings. Each category is graded as 0, 1, 2, or 4 points, yielding a total score between 0 and 24. When women with PP had PPAP score ≥8, they were considered to be at a high risk for AP and received placement of preoperative internal iliac artery occlusion balloon catheters. If they were found to have AP during CS, they underwent hysterectomy or placenta removal using advanced bipolar with balloon catheter occlusion. The predictive accuracy of PPAP score was evaluated. RESULTS: In total, 23 of the 175 women with PP were diagnosed as having AP, histopathologically or clinically. Twenty-one of 24 women with PPAP score ≥8 had AP, whereas two of 151 women with PPAP score <8 had AP. The scoring system yielded 91.3% sensitivity, 98.0% specificity, 87.5% positive predictive value, and 98.7% negative predictive value for predicting AP in women with PP. DISCUSSION: This prospective study demonstrated that PPAP scoring system may be useful for predicting AP in women with PP.

RESUMO

The aim of this prospective study was to determine clinical factors associated with adverse pregnancy outcomes in women with systematic lupus erythematosus (SLE). Fifty-six pregnancies from 46 women with SLE were enrolled. Risk factors for pregnancy loss, premature delivery, hypertensive disorders of pregnancy (HDP), and light-for-date neonate (LFD), were evaluated. Univariate and multivariate logistic regression analyses revealed a history of two or more pregnancy losses before 10 gestational weeks (GW) (OR 11.5, 95%CI 1.72-76.8) as a risk factor for pregnancy loss; low levels of blood complements (OR 7.55, 95%CI 1.10-51.9) and antiphospholipid syndrome (OR 26.5, 95%CI 3.17-219) as risk factors for premature delivery before 37 GW; SLEDAI score at conception (OR 1.68, 95%CI 1.05-2.68) and positive tests for two or more antiphospholipid antibodies (OR 6.89, 95%CI 1.13-41.9) as risk factors for premature delivery before 34 GW; prednisolone therapy >14mg/day (OR 7.55, 95%CI 1.10-51.9) as a risk factor for HDP; and low dose aspirin therapy (OR 0.21, 95%CI 0.05-0.97) decreased the risk for LFD neonate. These results have important implications for clinicians managing SLE complicated pregnancy.

RESUMO

We report two cases of pulmonary hypoplasia due to fetal ascites in symptomatic congenital cytomegalovirus (CMV) infections despite fetal therapy. The patients died soon after birth. The pathogenesis of pulmonary hypoplasia in our cases might be thoracic compression due to massive fetal ascites as a result of liver insufficiency. Despite aggressive fetal treatment, including multiple immunoglobulin administration, which was supposed to diminish the pathogenic effects of CMV either by neutralization or immunomodulatory effects, the fetal ascites was uncontrollable. To prevent development of pulmonary hypoplasia in symptomatic congenital CMV infections, further fetal intervention to reduce ascites should be considered.

RESUMO

BACKGROUND: The aim of this prospective cohort study was to evaluate the efficacy of maternal screening for congenital cytomegalovirus infection (CCI) using cytomegalovirus (CMV) immunoglobulin G (IgG) and the IgG avidity index (AI). METHODS: Pregnant women underwent screening of CMV IgG and AI measurements. IgG-negative women underwent remeasurement of IgG after educational intervention. Women with an AI ≤45% received further examinations, including measurement of CMV IgM. All newborns received polymerase chain reaction analyses of the urine, and CCI was diagnosed by the detection of CMV-DNA in the urine. Primary infection was defined as an AI <35% and/or positive IgM (>1.20 index). Serum samples from women with an AI >45% were stored, and the IgM levels were measured after delivery. The efficacy of AI and IgM for CCI screening was compared. RESULTS: A total of 1562 (71.2%) women tested positive for IgG. In this study, 10 newborns with CCI were detected. The presence of infection in 3 newborns from mothers with primary infection was predicted by screening of IgG and AI <35%. However, infection in 7 newborns from women with nonprimary infection could not be predicted by screening of CMV IgG, AI <35%, or IgM. The application of an AI <35% for CCI screening yielded 22.2% sensitivity, 95.0% specificity, 2.5% positive predictive value, and 99.5% negative predictive value and was similar to that of IgM (11.1% sensitivity, 93.2% specificity, 0.9% positive predictive value, and 92.7% negative predictive value). CONCLUSIONS: Maternal screening using CMV IgG and AI can identify pregnancies with CCI from primary infection, but overlooks a number of those from nonprimary infection.

RESUMO

BACKGROUND: This prospective study aimed to determine maternal clinical, laboratory, and ultrasound findings that effectively predict the occurrence of congenital cytomegalovirus (CMV) infection (CCI) in high-risk pregnant women. METHODS: Three hundred CMV immunoglobulin (Ig) M-positive pregnant women were enrolled. The maternal clinical and laboratory findings, including serum CMV IgM and IgG; IgG avidity index (AI); antigenemia assay (C7-HRP); polymerase chain reaction (PCR) for the detection of CMV-DNA in the maternal serum, urine, and uterine cervical secretion; and prenatal ultrasound findings, were evaluated. To determine predictive factors for the occurrence of CCI, logistic regression analyses were performed. RESULTS: In 22 of the 300 women, CCI was confirmed using PCR for CMV-DNA in newborn urine. Univariate analyses demonstrated that the presence of maternal flu-like symptoms, presence of ultrasound fetal abnormalities, serum titers of CMV IgM, positive results for C7-HRP, CMV IgG AI <40%, and positive PCR results in the uterine cervical secretion were statistically associated with the occurrence of CCI. Multivariable analysis revealed that the presence of ultrasound fetal abnormalities (odds ratio [OR], 31.9; 95% confidence interval [CI], 8.5-120.3; P < .001) and positive PCR results in the uterine cervical secretion (OR, 16.4; 95% CI, 5.0-54.1; P < .001) were independent predictive factors of CCI in CMV IgM-positive women. CONCLUSIONS: This is the first prospective cohort study to suggest that the presence of CMV-DNA in the maternal uterine cervical secretion and ultrasound fetal abnormalities are predictive of the occurrence of congenital CMV infection in high-risk pregnant women.

RESUMO

OBJECTIVES: To determine the risk factors for glucose intolerance (GI) during the postpartum period in women with gestational diabetes mellitus (GDM). METHODS: This prospective cohort study included 72 Japanese women with GDM who underwent 75 g oral glucose tolerance tests (OGTT) at 12 weeks after delivery. These women were divided into the GI group and the normal group based on postpartum OGTT. Risk factors for GI, including levels of blood glucose (BG), area under the curve (AUC) of glucose, AUC insulin, HbA1c, homeostasis model assessment-insulin resistance (HOMA-IR), HOMA-ß, insulinogenic index (II) and the oral disposition index (DI) in antepartum OGTT, were analyzed by logistic regression analyses. RESULTS: Of the 72 women, 60 (83.3%) were normal and 12 (16.7%) had GI. By univariate logistic regression analyses, fasting BG, AUC glucose, HOMA-ß, II and oral DI were selected as risk factors for GI. Multivariate logistic regression analysis revealed that the level of II in antepartum OGTT was a significant factor that predicted GI after delivery (odds ratio, 0.008; 95% CI, 0.0001-0.9; p < 0.05). CONCLUSIONS: II measured by OGTT during pregnancy might be a useful predictor of GI within the early postpartum period in women with GDM.
