Prevalence of hepatitis C virus genotypes in a Spanish liver transplant unit.
BACKGROUND
Among the at least six major identified genotypes of HCV, genotype 1b, the one associated with a poorer prognosis, is the most prevalent in Spain. We aimed to compare the distribution of hepatitis C virus genotypes in our liver transplant unit with that of the other HCV patients at our institution (n = 413) in order to assess whether genotype 1b is more prevalent among patients with more severe liver disease.


METHODS
One hundred eight patients of mean age 56 years included 81 (75%) OLT recipients and 27 (25%) with HCV cirrhosis. Determination of HCV genotypes was made with the Inno-LiPA HCV III.


RESULTS
The overall distribution of genotypes was: 1b, 93 patients (86.1%); 1a; eight patients (7.4%); 3, four patients (3.7%); 4; two patients (1.9%), and 2; one patient (0.9%). The distribution was similar among patients with cirrhosis and OLT. Genotype 1b patients were older. Eleven (78.6%) of 14 patients with hepatocellular carcinoma had genotype 1b. In the control group the distribution was: 1b, 287 patients (69.5%); 1a, 54 patients (12.1%); 3, 41 patients (9.9%); 4, 20 patients (4.8%), and genotype 2, 11 patients (2.7%). This differences in the distribution of genotypes between our population and the control group was statistically significant (P < .001).


CONCLUSIONS
Genotype 1b, the most prevalent genotype in our liver transplant unit, included older patients in whom hepatocellular carcinoma was common, perhaps due to their higher prevalence of cirrhosis.
