Hepatitis E virus (HEV) is a major public health problem in the developing countries. HEV infection in pregnant women is more common and fatal in the third trimester. The present study was designed to determine the seroprevalence of subclinical HEV infection in asymptomatic pregnant women.
A total of 116 asymptomatic pregnant women divided into 2 groups: Group 1 included 56 pregnant women with HCV positive serology and group 2 included 60 pregnant women with negative HCV serology were included in this study. Prevalence of anti-HEV antibodies and anti-HCV were determined by an enzyme linked immunosorbent assay (ELISA) kit.
The overall prevalence of anti-HEV IgG was highly significant among pregnant women with chronic HCV infection 40/56 (71.42%) than pregnant women free from chronic HCV infection 28/60 (46.7%) (P = 0.006). Chronic HCV infection in pregnant women appeared to be a risk factor associated with HEV IgG seropositivity (OR = 2.86, CI = 1.24-6.6). The seropositivity of anti-HEV IgG was significantly high in rural areas than urban areas (62.5% vs. 37.5%) in group 1 and (78.58% vs. 21.42%) in group 2 (P = 0.15) and OR = 2.2, CI = 0.65-7.7). A decrease in albumin level (P = 0.047) and an increase in bilirubin (P = 0.025), ALT (P = 0.032), and AST (P = 0.044) in pregnant women with positive HCV and IgG anti-HEV than the second group with negative HCV serology.
The seroprevalence of anti-HEV IgG in pregnant women is high in Egypt especially in rural areas. With chronic HCV coinfection, a marked increase in anti-HEV IgG seropositivity and significant worsening of the biochemical liver indices were noted. Increased public awareness about the sound hygienic measures for a less prevalence of HEV is strongly advised. The need for HEV vaccination for those at risk, especially pregnant ladies, should be considered.
戊型肝炎病毒(HEV)是发展中国家的一个主要公共卫生问题。孕妇感染HEV在妊娠晚期更为常见且致命。本研究旨在确定无症状孕妇中亚临床HEV感染的血清流行率。
本研究共纳入116例无症状孕妇,分为2组:第1组包括56例HCV血清学阳性的孕妇,第2组包括60例HCV血清学阴性的孕妇。采用酶联免疫吸附试验(ELISA)试剂盒测定抗HEV抗体和抗HCV的流行率。
慢性HCV感染孕妇中抗HEV IgG的总体流行率(40/56,71.42%)显著高于无慢性HCV感染的孕妇(28/60,46.7%)(P = 0.006)。孕妇慢性HCV感染似乎是与HEV IgG血清阳性相关的一个危险因素(OR = 2.86,CI = 1.24 - 6.6)。第1组农村地区抗HEV IgG血清阳性率显著高于城市地区(62.5%对37.5%),第2组农村地区抗HEV IgG血清阳性率显著高于城市地区(78.58%对21.42%)(P = 0.15),OR = 2.2,CI = 0.65 - 7.7。HCV和IgG抗HEV阳性的孕妇白蛋白水平降低(P = 0.047),胆红素、ALT(P = 0.032)和AST(P = 0.044)升高,高于HCV血清学阴性的第2组。
埃及孕妇中抗HEV IgG的血清流行率较高,尤其是在农村地区。合并慢性HCV感染时,抗HEV IgG血清阳性率显著升高,肝脏生化指标明显恶化。强烈建议提高公众对良好卫生措施的认识,以降低HEV的流行率。应考虑对高危人群,尤其是孕妇进行HEV疫苗接种。
