ABSTRACT The aim of this study was to examine the contribution of hepatitis B virus (HBV) and hepatitis C virus (HCV) to pregnancy-related complications including gestational diabetes mellitus (GDM), preterm birth (PTB), intrauterine growth restriction (IUGR), pre-eclampsia, antepartum haemorrhage and cholestasis. The Nationwide Inpatient Sample was queried for all pregnancy-related discharges, pregnancy complications and viral hepatitis from 1995 to 2005. Logistic regression was used to examine the association between HBV, HCV, HBV + HCV and pregnancy-related complications including GDM, PTB, IUGR, pre-eclampsia, antepartum haemorrhage, cholestasis and caesarean delivery. Model covariates included maternal age, race, insurance status, substance use and medical complications including liver complication, hypertension, HIV, anaemia, thrombocytopenia and sexually transmitted infections. Of 297 664 pregnant women data available for analysis, 1446 had a coded diagnosis of HBV, HCV or both. High-risk behaviours, such as smoking, alcohol and substance use were higher in women with either HBV or HCV. Women with HBV had an increased risk for PTB (aOR 1.65, CI [1.3, 2.0]) but a decreased risk for caesarean delivery (aOR 0.686, CI [0.53, 0.88]). Individuals with HCV had an increased risk for GDM (aOR 1.6, CI [1.0, 2.6]). Individuals with both HBV and HCV co-infection had an increased risk for antepartum haemorrhage (aOR 2.82, CI [1.1, 7.2]). There was no association of viral hepatitis with IUGR or pre-eclampsia. Women with hepatitis have an increased risk for complications during pregnancy. Research to determine the efficacy and cost-effectiveness of counselling patients about potential risks for adverse outcomes is warranted.

    ABSTRACT: Of the 5 types of viral hepatitis (HAV-HEV), HBV and HCV are by far the most common causes of chronic hepatitis in both pregnant and nonpregnant populations, causing more than 50% of cirrhosis cases and 78% of cases of primary liver cancer. Infection during pregnancy can have adverse effects on both the mother and her fetus. For all 5 viral hepatitis syndromes, early identification allows appropriate measures to be taken to optimize pregnancy outcomes and minimize the risk of perinatal transmission. This article reviews the prevention and management of all 5 viral hepatitis syndromes during pregnancy. Copyright © 2014 Elsevier Inc. All rights reserved.

    ABSTRACT: When the normal progression of pregnancy is threatened, inflammatory processes are often amplified in order to minimize detrimental effects and eliminate noxious agents. Inflammasomes are unique, intracellular, multiprotein assemblies that enable caspase-1 mediated proteolytic processing of the proinflammatory cytokine interleukin-1β, levels of which are elevated in some forms of preterm birth and maternal metabolic disorders. A comprehensive review based on a search of PubMed and Medline for terms and combinations of terms incorporating 'inflammation', 'inflammasome', 'pregnancy', 'preterm birth', 'pre-eclampsia', 'interleukin-1', 'caspase-1' and others selected to capture key articles. In the decade since the discovery of the inflammasome, between January 2002 and June 2014 over 2200 articles have been published. Articles in the reproductive field are scarce but there is clear evidence for a role of the inflammasome axis in pregnancy, preterm birth and the maternal metabolic syndrome. Further investigations on the inflammasome in pregnancy are needed in order to elucidate the biology of this unique structure in reproduction. Coordination of maternal, fetal and placental aspects of inflammasome function will potentially yield new information on the detection and transduction of host and non-host signals in the inflammatory response. © The Author 2014.

    ABSTRACT: The relationship between maternal HBV (hepatitis B virus) infection and pregnancy-induced hypertension (PIH) is inconclusive. Few studies have been conducted in rural areas of China. In order to examine the association between maternal chronic HBV infection and risk of PIH in Liuyang rural area China, we enrolled 6,195 eligible pregnant women in 2010-2011 in selected 14 towns of Liuyang on their first prenatal visit to local maternity care unit. A total of 461 subjects (7.44% (95%CI: 6.79%, 8.10%)) were identified with positive HBsAg status (exposed group) and 5734 were non-HBV carriers (unexposed group). Multivariate log-binomial regression models were used to estimate the risk of PIH, gestational hypertension (GH), and preeclampsia (PE) in relation to maternal chronic HBV infection. There are total of 455 subjects diagnosed with PIH (7.34% (95%CI: 6.70%, 7.99%)), including 371 GH (5.99% (95%CI: 5.40%, 6.58%)) and 81 PE (1.31% (95%CI: 1.07%, 1.64%)). The crude risk ratio between PIH, GH, PE and maternal HBV infection were 1.20 (95%CI: 0.88, 1.64), 1.30(95%CI: 0.93, 1.81) and 0.79 (95%CI: 0.32, 1.93), respectively. After adjustment for gravidity history, abortion history, family history of Diabetes Mellitus (DM) and family history of hypertension, positive HBsAg status was still not significantly associated with PIH (RR = 1.18, 95%CI: 0.87, 1.62), GH (RR = 1.27, 95%CI: 0.91, 1.78) or PE (RR = 0.79, 95%CI: 0.32, 1.95). Additional adjustment for maternal age, marital status, parity history, family history of DM, Body Mass Index at first antenatal visit, folic acid supplementation, smoking status during pregnancy and economic status of living area, multivariate analysis provided similar results. In conclusion, our study found that maternal chronic HBV infection prevalence rate is 7.4% among Liuyang rural area and there is no significant association between maternal HBV infection and the risk of PIH, GH or PE.
