Abstract
Background and Objectives
Hemodialysis is a major method of treatment for the patients of end-stage renal disease (ESRD). It so disposes them to some infections, specially blood born viruses. The aim of this study was to investigate the prevalence of serological markers for HBsAg, anti-HBs, anti-HCV and HIV Ab in hemodialysis patients in Zanjan city.
 
Materials and Methods
After 10 ml blood samples were used for detection of markers for hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBs Ab), antibody to HCV (anti-HCV), HIV antibody by ECL. Data were analyzed by c², t test and fisher exact test.
 
Results
Positive HBsAg was found in .2.3%, HBs Ab 65.3% and HCV Ab 1.1% of cases. HIV Ab cases were negative in these patients.
 
Conclusions 
The prevalence of HBsAg in hemodialysis patients has been re­ported to be lower than in the general population. In this study, the prevalence of HBs Ab compared to other studies in Iran and other countries is not much different. The results show that the prevalence of HCV Ab in hemodialysis patients is the same with the general population and the prevalence of HIV Ab in this study is similar to the result recent studies.
