Objective: Hepatitis E virus (HEV) is one of the prevalent nosocomially transmitted agents among patients on maintenance hemodialysis due to parenteral transmission of HEV and immunocompromised condition of chronic hemodialysis patients. Therefore, this study aimed to investigate prevalence, risk factors, and genotypic pattern of HEV infection among hemodialysis patients in South of Iran. Methods: All patients on maintenance hemodialysis attending the hemodialysis centers of Bushehr, Borazjan, and Genaveh cities for regular hemodialysis were enrolled in this study. Serum samples were tested for the presence of anti-HEV antibodies using ELISA kit. The serum samples were further tested for detection of HEV RNA using nested RT-PCR. Results: Of 226 hemodialysis patients, 155 patients (68.6%, 95% CI: 62.3%–74.3%) were positive for anti-HEV IgG antibody, of which 33 patients (14.6%, 95% CI: 10.6%–19.8%) had anti-HEV IgM antibody. The prevalence of anti-HEV IgG and anti-IgM antibodies in non-hemodialysis controls were 65.1% and 9.6%, respectively. Although the hemodialysis patients had higher prevalence of HEV than the controls, the difference was not significant. All samples were negative for HEV RNA. HEV seroprevalence among hemodialysis patients was not significantly associated with place of residency, ethnicity, level of education, gender distribution, hemodialysis duration, and levels of liver enzymes. HEV seropositive patients had significantly higher mean age compared to seronegative patients. Conclusion: This study reports the highest seroprevalence of HEV among hemodialysis patients in Iran. Inapparent HEV infection in the dialysis setting calls for regular screening of hemodialysis patients regardless of the hemodialysis duration, clinical symptoms, and liver function parameters.
