ABSTRACT
Background: Hemodialysis (HD) is one of the most common causes of blood-borne infections. In order to prevent viral hepatitis and confront with the virus on the next step, health providers specify infected patients by screening and vaccination. This study is designed to investigate the prevalence of Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infections in HD patients in Mazandaran, Iran. Methods: The medical records of 216 patients referred to the hemodialysis centers were evaluated in this cross-sectional study between 2019 and 2020. The collected data was analyzed using t-test and Chi-square. Results: Among 216 patients, 106 cases were female (49.07%) and 110 subjects were male (50.9%). The mean age was 40.1 y/o in females and 50.9 y/o in the male patients. The study recorded nine HBs-Ag positive (prevalence: 0.06%) and 15 HCV-Ab positive (prevalence: 6.94%) patients. Also, the most common co-morbidities were diabetes and hypertension. It was observed that 13 patients from 34 patients with negative HBs-Ag (who had 10-100 U HBs-Ab in the first stage) experienced sudden drop in the antibody titration to less than 10 U (P < 0.05). From 50 HBs-Ag negative patients with HBs-Ab more than 100 U in the first stage, antibody titration of five patients was decreased to less than 10 U in the second stage (P < 0.05). Conclusions: The prevalence of HCV and HBV was low in HD patients in Mazandaran province. However, due to the large number of patients with non-protective HBs-Ab levels, there is a risk of an increased prevalence of the disease.
