    Abstract:
    OBJECTIVES: To investigate the prevalence of hepatitis E virus (HEV) among patients with chronic hepatitis B and chronic hepatitis C, serum samples were collected between January and December 2004 from patients with chronic hepatitis B and chronic hepatitis C. METHODS: There were 190 adult patients with chronic hepatitis B virus (HBV) and 174 with chronic hepatitis C virus (HCV) infection in the study group. As the control group, a cohort of 178 age- and sex-matched individuals without known liver disease was selected. RESULTS: Anti-HEV IgG antibodies were positive in 26/190 (13.7%) of chronic HBV and 94/174 (54%) of chronic HCV patients. In the control group anti-HEV positivity was 15.7% (28/178). There was no difference in the percentage of chronic HBV patients and control group who were positive for anti-HEV antibody, but the presence of HEV infection was significantly higher in chronic HCV patients. CONCLUSIONS: Our findings suggest that HEV and HCV might share a common route of transmission in our region. We recommend that preventive measures against HEV should be undertaken in chronic HCV patients as superinfection with HEV can cause a more severe pattern of disease in chronic hepatitis patients.
