BACKGROUND: Hepatitis C virus (HCV) is a controversial indication for liver transplantation (LT) in HIV-infected patients due to reportedly poor outcomes.

METHODS: This prospective U.S. multicenter cohort study compared patient and graft survival in 89 HCV-HIV coinfected versus 2 different controls groups: 235 HCV monoinfected LT controls and all U.S. transplant recipients ≥65 years.

RESULTS: The 3-year patient and graft survival rates (95% CI) were 60% (47-71%) and 53% (40-64%) in HCV-HIV versus 79% (72-84%) and 74% (66-79%) in HCV recipients (both p<0.001) and HIV infection was the only factor significantly associated with reduced patient and graft survival. Among HCV-HIV patients, older donor age (HR=1.3 per decade), combined kidney-LT (HR=3.8), HCV-positive donor (HR=2.5), and body mass index (BMI) less than 21 kg/m(2) (HR=3.2) were independent predictors of graft loss. In patients without these latter 3 factors, patient and graft survival were similar to those in U.S. LT recipients. The 3-year incidence of treated acute rejection was 1.6-fold higher in HCV-HIV versus HCV (log rank p=0.02) but cumulative incidence of severe HCV disease (29% versus 23% at 3 years, respectively) were not significantly different (p=0.21).

CONCLUSIONS: Patient and graft survival are lower in HCV-HIV compared to HCV alone LT patients. Importantly, rates of treated acute rejection but not HCV disease severity are significantly higher in HCV-HIV compared to HCV recipients. Our results indicate that HCV per se is not a contraindication to LT in HIV patients but recipient and donor selection as well as management of acute rejection strongly influence outcomes.
