RESUMO
Hepatitis C virus (HCV) infection is a serious public health problem, since 80 percent to 85 percent of HCV carriers develop a persistent infection that can progress into liver cirrhosis and hepatocarcinoma. Considering that the response of hepatitis C patients to combination therapy with interferon and ribavirin depends on HCV characteristics as well as on host features, we made a retrospective analysis of demographic and anthropometrical data and HCV genotype distribution of chronic hepatitis C patients treated in public and private reference centers in Brazil. The medical records of 4,996 patients were reviewed, 81 percent from public and 19 percent from private institutions. Patients' median age was 46 years, and there was a higher prevalence of male (62 percent) and white patients (80 percent). The analysis of HCV-infecting strains showed a predominance of genotype 1 (64 percent) over genotypes 2 and 3. The patients' mean weight was 70.6 kg, and 65 percent of the patients weighed less than 77kg. Overweight and obesity were observed in 37.8 percent and 13.6 percent of the patients, respectively. Since a body weight of 75 kg or less has been considered an independent factor that significantly increases the odds of achieving a sustained virological response, the Brazilian population seems to have a more favorable body weight profile to achieve a sustained response than the American and European populations. The finding that 65 percent of chronic hepatitis C patients have a body weight of 77 kg or less may have a positive pharmacoeconomic impact on the treatment of genotype 1 HCV patients with weight-based doses of peginterferon.
