Prevalence of Hepatitis C Virus Infection in Hemodialysis Patients

The prevalence of hepatitis C virus (HCV) infection in hemodialysis patients (HD) has decreased significantly during the past decade in most HD units. To evaluate the cause(s) of this reduction, we studied the HCV antibodies measurements in 1006 HD patients in the Province of Mazandaran, Iran, from January 2001 to December 2006. In December 2001, the prevalence of antibody to HCV was 18%, whereas by December 2006, it decreased to12%. Causes implicated in the reduction of prevalence of HCV infection in HD patients include a low percentage of new anti-HCV+ patients, a decrease in the conversion rate in HD patients, and more strict infection control measures in the dialysis units.
