Hepatitis A virus infection during pregnancy in Korea: Hepatitis A infection on pregnant women

Abstract

ObjectiveAlthough there is a large body of data on acute hepatitis A virus (HAV) worldwide, data regarding the occurrence of HAV during pregnancy is limited. It is commonly acknowledged that HAV is not associated with severe outcomes or complications during pregnancy. In contrast, there are several reported cases of vertical HAV transmission. Moreover, it has been recently reported that HAV infection during pregnancy is associated with gestational complications. In Korea, the incidence of HAV infection has increased from 317 cases in 2002 to 13,117 cases in 2009. However, HAV infection during pregnancy is rarely reported in Korea.MethodsThis study was conducted as a retrospective cohort series of pregnant women presenting to Korea University Medical Center between January 2000 and October 2009 in whom a diagnosis of HAV infection was made.ResultsDuring study period, there were 12 cases of HAV in pregnant women, including two cases with preterm contraction, two cases with cholestatic hepatitis, and one case with fetal ascites and intra-abdominal calcification.ConclusionHAV infection during pregnancy is associated with high prevalence of maternal and fetal complications. Because the incidence of HAV infection in women of reproductive age is increasing, a further focus on preventing HAV infection during pregnancy is warranted.
