Hepatitis E Virus and Serum Level Aminotransferases in Blood Donors

Background: Hepatitis E virus (HEV) infection is a self-limiting viral infection that can lead to severe complications and death. In different regions the epidemiology of this infection varies. In this study we evaluated the seroepidemiology of hepatitis E infection in Jahrom, a city in southern Iran. Methods: This was a cross-sectional descriptive study of serum samples from ۴۷۷ subjects, including ۳۰ females and ۴۴۷ males. HEV immunoglobulin G (IgG) and immunoglobulin M (IgM) were measured by enzyme-linked immunosorbent assays (ELISA). Alanine transaminase (ALT) and aspartate transaminase (AST) levels were also determined. Four hundred forty-seven subjects were male and ۳۰ were female. Subjects were classified by age and sex. Results: One woman (۳.۳%) and ۲۵ men (۵.۵%) were positive for HEV antibodies (IgG and/or IgM). There was found an association between serum level of aminotransferases and seropositivity for HEV. Conclusion: The result of this study indicates that HEV is an etiological factor for hepatitis in this area of IRAN. The cost benefit of active immunization in endemic regions should be evaluated because an outbreak could have tragic consequences.
