The Prevalence of Hepatitis B Surface Antigen and Hepatitis D Virus Antibody Positivity Among Hemodialysis Patients and Patients With Beta-Thalassemia Major

Patients, who receive hemodialysis and patients with beta-thalassemia major are at great risk for blood-borne viral infections, chiefly different types of hepatitis.
This study aimed at assessing the prevalence of hepatitis B and D among hemodialysis patients and patients with beta-thalassemia major in Kashan, Iran.
This cross-sectional study was conducted in 2016 on 108 patients on hemodialysis and 34 patients with beta-thalassemia major in Kashan, Iran. After explaining the aim of the study to the participants and securing their informed consents, data on their demographic and health-related characteristics were collected through a questionnaire. Then, a five-milliliter venous blood sample was obtained from each participant and tested using enzyme-linked immunosorbent assay technique for hepatitis B surface antigen and hepatitis D virus antibody. The data were entered in the SPSS program (v. 16.0) and analyzed using the Chi-square and the independent-sample t tests.
The prevalence of hepatitis B surface antigen positivity among patients on hemodialysis and patients with beta-thalassemia major was 3.7% and 8.8%, respectively. Moreover, the prevalence of hepatitis D virus antibody positivity among these patients was 2.9% and 1.9%, respectively. The prevalence of hepatitis B surface antigen positivity among patients on hemodialysis had a significant relationship with history of addiction and history of unprotected sex.
The prevalence of hepatitis B and D was respectively 3.7% and 8.8% among hemodialysis patients and 2.9% and 1.9% among patients with beta-thalassemia major. Effective strategies should be employed to minimize the risks of hepatitis B and D transmission among hemodialysis patients and patients with beta-thalassemia major. Moreover, regular screening programs are needed for early diagnosis and treatment of viral hepatitis among these patients.
