Treatment with pegylated interferon alpha 2b and ribavirin in patients unresponsive to previous treatments with standard interferon as monotherapy or combined with ribavirin
Background: little information is available on the effect of pegylated interferon (PEG) and ribavirin (RBV) in patients with chronic hepatitis due to virus C (CHC) who were non-responders to previous treatment. Objectives: to evaluate response to treatment in patients who were non-responders to previous treatment. Methods: one hundred and twenty-four patients who were non-responders to previous treatment were included. All patients were treated with PEG alpha 2b interferon (dose: 1.5 mg/kg body weight) and RBV (weight-dependent dosage). A qualitative PCR of virus C after six months was evaluated. In those in whom this was positive, treatment was discontinued; in those who were negative treatment was continued to the end of the year. Results: response following treatment (RFT) was 35.4% (44 patients), and sustained viral response (SVR) 29.8% (37 patients). No relation was observed between RFT, SVR and any previous treatment. RFT was dependent on low initial viremia and SVR was significantly and independently related to low serum hepatitis C RNA and a non-1 genotype. In general, treatment was well tolerated. Medication was discontinued in 5 patients, and doses reduced in 18. Conclusion: on retreatment with PEG and RBV a SVR of 29.8% was achieved in patients who had not responded to previous treatment, so its use in this group of patients is indicated.
