Abstract

Renal transplant recipients are known to be susceptible to viral infections, with more severe clinical presentations compared to healthy persons. Hepatitis E is generally a self-limited disease, which is caused by hepatitis E virus. Recently, hepatitis E has become more important in organ transplant recipients, because of new findings regarding the potential for chronic infections in this patient group. Objectives: This study aimed to evaluate the seroprevalence of anti-HEV IgG among kidney transplant recipients in Urmia, in the north-western region of Iran. Patients and Methods: 91 patients were selected randomly from amongst patients who had undergone kidney transplantation in Urmia, Iran. Each patient was tested for the presence of anti-HEV IgG antibody using an enzyme-linked immunosorbent assay (ELISA, Dia.Pro; Diagnostic Bioprobes, Italy). Results: 28 subjects (30.8%) were seropositive for anti-HEV IgG. Seropositive patients were generally older than seronegative patients (P = 0.009). There was no correlation between HEV infection and the level of education (P = 0.206), the history of blood transfusion (P = 0.164), or history of pre-transplantation hemodialysis (P = 0.228). There was no significant difference in the serum alanine aminotransferase (ALT) levels of the anti-HEV seropositive and seronegative patients. Multinomial logistic regression analysis indicated no significant relationship between HEV infection and increase in ALT levels, even after controlling for treatment with azathioprine (P = 0.79, OR = 1.12; 95% CI: 0.45–2.76). Conclusion: The anti-HEV IgG antibody has a high prevalence in Iranian kidney transplant recipients, and it is significantly higher in comparison with previous studies in the general population or in hemodialysis patients
