title: Genotyping of hepatitis C virus (HCV) in infected patients from Northeast Mexico.
abstract: Information about HCV genotypes in infected patients from different regions of Mexico is limited.
  
  
  OBJECTIVE
  To determine the prevalence of HCV genotypes in a group of HCV infected patients who attended a third level Hospital in Northeast of Mexico.
  
  
  METHODS
  Genotyping analysis was performed using the InnoLiPA-HCV genotype assay in 147 patients (65 males and 82 females, mean age 44 +/- 12 years) with positive anti-HCV antibodies and detectable HCV-RNA levels.
  
  
  RESULTS
  Infected individuals were more likely to be female (56%). Histological data showed that 63% of the patients had chronic hepatitis, while the remainder presented cirrhosis (37%). The most frequent HCV genotype was 1 (73%). We found the following distribution: genotype 1 (2.7%), 1a (28.6%), 1b (37.4%), 1a/1b (4.1%), 2a (1.4%), 2b (8.8%), 2c (0.7%), 2a/2c (2.7%), 3 (2%), 3a (10.2%), 4 (0.7%) and 4c (0.7%). The most frequent associated risk factor was blood transfusion (72.5%).
  
  
  CONCLUSIONS
  Prevalence of HCV genotypes in the Northeast of Mexico is similar to those reported previously in other Mexican regions and the most frequent risk factor continues being blood transfusion.
