Abstract
BACKGROUND: To determine the prevalence of hepatitis C virus (HCV) genotypes in the area of El Ferrol, as well as their distribution according to risk factors. METHODS: A total of 479 patients with hepatitis C were studied, including 254 with no known risk factors, 161 intravenous drug abusers (IVDA) and 64 with a history of blood transfusions. The presence of HCV RNA was studied by RT-PCR, and a reverse hybridization method (INNO-LiPA) was used for genotyping. RESULTS: Genotype distribution was as follows: 1b, 269 (56.2%); 1a, 79 (16.5%); 3a, 59 (12.3%); 4c/4d, 35 (7.3%); 1, 19 (4.0%); 2a/2c, 3 (0.6%); 4, 3 (0.6%); 2b, 2 (0.4%). In 10 patients (2.1%) genotype could not be determined. In patients with no known risk factor, the predominant genotype was 1b, detected in 191 of the 254 patients in this group (75.2%). Distribution of genotypes was more varied in the IVDA group, with the most frequent being 1a in 49 (30.4%) and 3a in 43 (26.7%). In the 64 patients who had received transfusions, 1b was predominant, detected in 54 of 64 patients (84.4%). CONCLUSIONS: The predominant HCV genotype in our area is 1b. Differences in genotype distribution were observed in the population groups studied, according to their underlying risk factors.
