RESUMO
Hepatitis C is a common cause of end-stage liver disease, and the main indication for liver transplantation in Latin America. Treatment of hepatitis C infected patients improves important long-term outcomes as mortality. Sustained viral response is reached in near 50% of patients with the previous management based in pegylated interferon and ribavirin. Recently new drugs were available increasing sustained viral response significantly, changing the standard of care to triple therapy. This guidelines provides a framework for practitioner in Latin America, to the management of patients with hepatitis C chronic infection.

BACKGROUND: The most important factors to predict the sustained virological response (SVR) are the genotype and the fibrosis grade, although there are other predictive factors to be considered, mainly in HCV/HIV coinfected patients. AIM: To evaluate different prognostic factors to obtain the SVR in HCV monoinfected and HCV/HIV coinfected genotype 1 patients emphasizing the type of early virological response (EVR)-complete or partial. METHODS: This is a cohort study, retrospective, where the registers of HCV monoinfected or HCV/HIV coinfected patients, genotype 1, treated with pegylated interferon + ribavirin were reviewed. The prognostic factors: age greater than 40 years, viral load higher than 600,000UI/mL, and fibrosis grade (score METAVIR) were evaluated pre-treatment, and also the EVR considering the reduction of 100 times of the basal viral load (partial EVR) or negative PCR (complete EVR) in the week 12. In the statistical analysis, multivariate analysis was used. The significance level adopted was 5%. RESULTS: There were 323 HCV monoinfected and 59 HCV/HIV coinfected. The SVR was 35.3% in monoinfected and 23% in coinfected patients. The worst results was observed in those with age greater than 40 years, high viral load, pronounced fibrosis (F4) and partial EVR, with an expected probability of 1.9% for SVR in those coinfected and 3.8% in monoinfected. In conclusion, patients with cirrhosis HCV genotype 1, age greater than 40 years, high viral load, coinfected with HIV or not, will present a low SVR if did not obtain negative PCR in week 12, and should be evaluated for discontinuation.
