High seroprevalence against hepatitis E virus in patients with chronic hepatitis C virus infection
2017
Abstract Background Hepatitis E virus (HEV) genotype 3 is endemic in Europe. Superinfection with HEV in patients with underlying chronic liver disease can cause hepatic decompensation leading to increased morbidity and mortality. Objectives The prevalence of anti-HEV antibodies was investigated in 204 patients with chronic hepatitis C virus (HCV) infection and different stages of fibrosis. Study design Sera were analyzed for anti-HEV IgG, IgM and HEV RNA. Results The median age of the patients was 55 years (IQR 40–62 years); 126 (62%) were men. Ninety-eight (48%) patients had a METAVIR fibrosis stage F2 or higher. The prevalence of anti-HEV IgG was 30% (62/204), which was significantly higher than among Swedish blood donors (17%, p Conclusions When adjusted for age, the prevalence of anti-HEV antibodies was significantly higher in patients with previous or current malignant liver disease compared to blood donors. The lack of significant correlation between HCV and HEV infections indicate low level of transmission of HEV by IDU. HEV infections warrant more attention, especially in patients with preexisting liver disease.
