    Abstract:
    OBJECTIVE: To describe efficacy and safety in clinical practice of pegylated interferon plus ribavirin (INFpeg-Riba) in the treatment of hepatitis C viral infection (HCV) in HIV infected patients. METHODS: Monocentric retrospective study with inclusion of all patients who received at least once INFpeg-Riba before April 1st 2003. All patients were followed up to six months after the end of HCV therapy. RESULTS: Thirty two HIV-positive patients (23 men and 9 women) with chronic hepatitis C treated by INFpeg-Riba were included. The mean age was 43 years. Fourteen patients carried HCV genotype 2 or 3 (43 %) and 18 patients carried genotype 1 or 4 (57%). The Metavir score of fibrosis showed fibrosis F1 (N =3), F2 (N =14), F3 (N =7) and F4 - cirrhosis (N =8). Twenty six patients (81%) were naive for anti hepatitis C drugs. Thirty one per cent of patients were at AIDS stage and 84% were receiving antiretroviral drugs. The mean CD4 cell count was 469 /ml and the plasma RNA HIV was less than 50 copies /ml in 57% of the cases. Adverse events leading to reduction of dose of drugs occurred in 40% and adverse events leading to discontinuation treatment occurred in 12%. A decline of CD4 cell count <200 CD4/ml was observed in 15%. Clearance of HCV-RNA in end of treatment was seen in 46 % and sustained virological response in 34 %. The main predictors of sustained virological response were HCV genotype 2 or 3 (P =0.04) and plasma HIV RNA less than 50 copies/ml (P =0.001). The predictive value of good virological response of a CD4 cell count >350/ml before treatment was very near the statistical significancy (p =0.07). CONCLUSIONS: The efficacy of pegylated interferon plus ribavirin in HIV-HCV co-infected patients is disappointing mainly due to a poor tolerance. In addition to HCV genotype, plasma HIV RNA level and CD4 cell count were essential to predict INFpeg-Riba response and should be taken into account in the process leading to the initiation of such therapy in HIV-HCV co-infected patients.
