| Summary: | Background. Efficacy and safety of Pegylated Interferon alfa (PegIFN)-Ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) in routine clinical practice seems to be comparable with results of randomizedcontrolled trials.Aims. To evaluate the efficacy, tolerability and safety of CHC treatment with PegIFN + RBV in “real world” patients in Argentina and to analyze factors associated with SVR.Methods. Medical records of patients treated according to current guidelines from 2001 to 2008 were reviewed.Results. 235 patients were included and 80.8% completed treatment. Discontinuation occurred in 7.6% due to adverse events (AE), and 1.2% dropped-out treatment. Overall SVR was 60.8%. Multivariate analysis demonstrated that being naive (p 0.031) and low basal viral load (p 0.006) were associated with SVR, whereas F3-F4 (p 0.001) and elevated ALT (p 0.023) were associated with non-response. 80% of planned doses completed was associated with 74% SVR (p <0.001). At least one AE was reported in 93.6% of the patients: neutropenia in 27.6%, thrombocytopenia in 15.3%, anemia in 38.7%, psychiatric symptoms in 63.4%, thyroid dysfunction in 10.2%.Conclusion. Efficacy, tolerability and safety of treatment of CHC in daily practice in Argentina are similar to those reported in randomized controlled trials.
