title: [Epidemiology and prevention of HCV infection in dialysis centers].
abstract: From many epidemiological studies comes out that haemodialysis patients are at high risk of hepatitis C virus (HCV) infection. This review shows the results of several prevalence and incidence studies carried out in dialysis centres. The prevalence of anti-HCV antibodies in haemodialysis patients varies from 20% to 38%. From these surveys comes out that serodiagnostic tests, usually employed in laboratory diagnosis (ELISA and RIBA), may underestimate the true prevalence of HCV infection. The very important risk factors in the haemodialysis units are blood transfusion and the length of time on haemodialysis. Nevertheless, these are not sufficient to explain completely the high prevalence of subjects HCV positive among the dialysis patients. Contamination of environmental surfaces, caused by a non correct application of the asepsis and disinfection techniques, could be, according to several authors, the more important cause of this infection among the dialysis patients.
