BACKGROUND:

Recurrence of hepatitis C viremia after orthotopic liver transplantation (OLT) is nearly universal, leading to variable outcome from no to severe recurrent disease. In the present study, the prognostic relevance of hepatitis C virus (HCV) genotypes and viremia for the development and severity of graft hepatitis was investigated.

METHODS:

A total of 79 patients with chronic hepatitis C who could be followed for 1 to 78 months (mean: 30 months) after OLT were included in this study. HCV RNA concentrations were measured before OLT, 1 month after OLT, as well as in the long-term follow-up after OLT in 54 of the 79 patients.

RESULTS:

Graft hepatitis could be documented in 40 of the 79 patients (51%), and 7 of them (9%) progressed to liver cirrhosis. More severe forms of graft hepatitis predominated in patients with subtype 1b infection, and all seven patients with progression to liver cirrhosis had subtype 1b (P=NS). Neither the pretransplant nor the posttransplant HCV RNA levels were significantly associated with the occurrence of graft hepatitis. However, there was a trend of more severe recurrent disease in subtype 1b-infected patients with high level viremia in the early course after OLT.

CONCLUSIONS:

Pretransplant HCV virological markers are not helpful to predict the outcome after OLT. However, it should be further investigated whether estimation of HCV genotype and viremia levels very early after OLT, i.e., within the first weeks, may be a better approach to recognize high-risk patients.
