Recurrent hepatitis C (HCV) and biliary complications (BC) are major causes of post liver transplant morbidity and mortality. The impact of these complications may be additive or synergistic. We performed a retrospective cohort study to analyze the effects of HCV and BC on all patients transplanted at two institutions over 6 years. BC was defined by imaging findings in the setting of abnormal liver function tests that required intervention. The primary outcomes were graft and patient survival over a mean 3.4 years. 709 patients (619 deceased, 90 living donor) were included, 337 with HCV and 372 without. BC was diagnosed more frequently in patients with HCV, 26% versus 18% (p = 0.008). One-year and overall patient and graft survival were significantly lower in patients with HCV, but BC impacted only 1-year graft survival. The combination of BC and HCV had no additional impact on survival or fibrosis rates on 1-year protocol biopsies. Multivariate analysis revealed HCV (HR 2.1) and HCC (HR 1.9) to be independent predictors of mortality. Since BC are diagnosed more frequently in HCV patients and only affect early graft loss, it is likely that recurrent HCV rather than BC accounts for the majority of adverse graft outcomes.

Abstract

Recurrent hepatitis C (HCV) and biliary complications (BC) are major causes of post liver transplant morbidity and mortality. The impact of these complications may be additive or synergistic. We performed a retrospective cohort study to analyze the effects of HCV and BC on all patients transplanted at two institutions over 6 years. BC was defined by imaging findings in the setting of abnormal liver function tests that required intervention. The primary outcomes were graft and patient survival over a mean 3.4 years. 709 patients (619 deceased, 90 living donor) were included, 337 with HCV and 372 without. BC was diagnosed more frequently in patients with HCV, 26% versus 18% (p = 0.008). One-year and overall patient and graft survival were significantly lower in patients with HCV, but BC impacted only 1-year graft survival. The combination of BC and HCV had no additional impact on survival or fibrosis rates on 1-year protocol biopsies. Multivariate analysis revealed HCV (HR 2.1) and HCC (HR 1.9) to be independent predictors of mortality. Since BC are diagnosed more frequently in HCV patients and only affect early graft loss, it is likely that recurrent HCV rather than BC accounts for the majority of adverse graft outcomes.
