RESUMO
BACKGROUND: In the period 2000 2011, chronic hepatitis C virus infection (HCV infection) was primarily treated with a combination of pegylated interferon and ribavirin. New antiviral drugs, which are effective but very expensive, are in the process of replacing this regimen. We have investigated the results pegylated interferon and ribavirin have yielded in ordinary clinical practice and examined the part this treatment may play in the near future. MATERIAL AND METHOD: We included in this retrospective study HCV-RNA-positive, treatment-naive patients at Stavanger University Hospital, Akershus University Hospital and Østfold Hospital who received at least one dose of pegylated interferon in combination with ribavirin in the period 2000 2011. The primary endpoint was sustained virologic response (SVR). Predictors for SVR were identified by means of logistic regression analysis. RESULTS: Of 588 included patients, 69.6% (409/588) achieved SVR, 14.3% (84/588) suffered relapse and 16.1% (95/588) showed non-response. In a multivariate analysis, genotypes 2 or 3 and low age at treatment start were independent predictors of SVR. A total of 85.4% of patients aged ≤ 40 years with genotype 2 or 3 had SVR. INTERPRETATION: We found good results for treatment of young patients with genotype 2 or 3 with pegylated interferon and ribavirin. Low age and viral genotype were predictors of sustained virologic response (SVR).
