戊型肝炎病毒(hepatitis E virus,HEV)是引起急性肝炎的主要原因之一。戊型肝炎通常是一种自限型疾病,但对孕妇和胎儿存在十分严重的危害,妊娠晚期孕妇感染HEV后死亡率高达25%,并极易造成胎儿早产、流产或死胎。目前HEV感染导致孕妇较高死亡率的原因还不清楚,本文将对HEV感染孕妇的流行病学及可能的致病机制作一综述。
Hepatitis E virus (HEV) is one of the major causes of acute hepatitis. Hepatitis E is a type of self-limited disease that is extremely harmful to pregnant women and fetuses. Pregnant women with late pregnancy experience up to 25% mortality from HEV infection and can easily cause premature birth, miscarriage or stillbirth. At present, the cause of the high mortality rate of pregnant women caused by HEV infection is still unclear. This article reviews the epidemiology and possible pathogenesis of HEV-infected pregnant women.
