Prevalence of hepatitis C, hepatitis B and HIV infection among haemodialysis patients in Ibn-Rochd university hospital, Casablanca

The viral infections are frequent in haemodialysis patients, notably those due to the hepatitis C virus (HCV), the hepatitis B virus (HBV) and the human immunodeficiency virus (HIV). The objective of this study is to determine the prevalence of the hepatitis C, the hepatitis B, the HIV infection in haemodialysis patients and the main risk factors for hepatitis C in the chronic haemodialysis patients treated in haemodialysis unit of Ibn Rochd University Hospital in Casablanca. This retrospective study was performed in 186 chronic haemodialysis patients and showed a high prevalence of HVC infection (76%), the prevalence of HBV infection was at 2%, none of the patients had detectable antibodies of HIV. Among the patients infected by the HCV, the mean duration of dialysis was 8,7 years. The mean number of blood units transfused was 16,5. Seventeen patients (11%) had no history of blood transfusion. In conclusion, the blood transfusion is not considered to be a like a major risk factor of the HCV infection in haemodialysis patients and this since the systematic detection of the anti-HCV antibodies in the blood donors. The nosocomial transmission of HCV seems to be the main risk factor HCV infection in the haemodialysis units requiring a strict adherence to infection control procedures for prevention of HVC infection in haemodialysis patients.
