Aim: Cholestatic hepatitis C is one of the most serious but still unaddressed disorders after liver transplantation. Methods: In this study, we analyzed 49 patients who underwent living-donor liver transplantation (LDLT) to treat hepatitis C virus (HCV) infection. Results: Five patients developed cholestatic hepatitis C, with total bilirubin of 15.2±3.1mg/dL at diagnosis 6.2±1.0 weeks after LDLT. Univariate analysis showed that larger graft to standard liver volume ratio, higher HCV RNA titer at 2 weeks, earlier peak HCV RNA titer and cytomegalovirus infection were the significant risk factors. The development of cholestatic hepatitis C was not significantly associated with interleukin-28B genotype (rs8099917); four out of five affected patients had the T/T genotype. Multivariate analysis showed that higher HCV RNA titer at 2 weeks was the only significant factor (P=0.026) for the development of cholestatic hepatitis C. Receiver-operator curve analysis showed that that HCV RNA titer of more than 7.2log10IU/mL was the optimal cut-off for characterizing cholestatic hepatitis C. All of the patients were serum HCV RNA negative after treatment with pegylated interferon and ribavirin and all the patients are alive. Conclusion: Early extensive viremia, but not the rs8099917 genotype, was the only predictor for cholestatic hepatitis C after LDLT.
