Recurrence of hepatitis C virus infection after orthotopic liver transplantation: role of genotypes.
In this study, we evaluated the correlation between alanine aminotrasferase levels and hepatitis C virus genotypes in liver transplant patients. We studied 18 patients who had undergone orthotopic liver transplantation because of end-stage cirrhosis (n = 9) or hepatocellular carcinoma (n = 9) hepatitis C virus related. Serum HCV-RNA testing was performed monthly on all the 18 series of serum samples from the first week after liver transplant until the end of the follow up, this period ranging from 1 to 39 months. After liver transplantation, serum HCV-RNA was detected in 14 patients (78%). Of the 8 patients infected with subtype 1b. 1 remained asymptomatic, 2 developed acute liver failure and 5 developed chronic hepatitis. In patients infected with types 1a (Choo et al., 1989), 2a (Choo et al., 1989), with a mixed infection 1b/3 (Kuo et al., 1989) or with an undetermined genotype, significant laboratory abnormalities were not observed. Recurrence of hepatitis C virus infection after liver transplantation is common, and recurrent hepatitis occurs in 50% of cases. Genotype 1b appears to be associated with a higher rate of recurrent hepatitis, compared to other genotypes.
