ABSTRACT Human immunodeficiency virus (HIV) infection accelerates liver disease progression in patients with hepatitis C virus (HCV) and could shorten survival of those awaiting liver transplants. The Model for End-Stage Liver Disease (MELD) score predicts mortality in HIV-negative transplant candidates, but its reliability has not been established in HIV-positive candidates.
We evaluated predictors of pretransplantation mortality in HIV-positive liver transplant candidates enrolled in the Solid Organ Transplantation in HIV: Multi-Site Study (HIVTR) matched 1:5 by age, sex, race, and HCV infection with HIV-negative controls from the United Network for Organ Sharing.
Of 167 HIVTR candidates, 24 died (14.4%); this mortality rate was similar to that of controls (88/792, 11.1%, P = .30) with no significant difference in causes of mortality. A significantly lower proportion of HIVTR candidates (34.7%) underwent liver transplantation, compared with controls (47.6%, P = .003). In the combined cohort, baseline MELD score predicted pretransplantation mortality (hazard ratio [HR], 1.27; P < .0001), whereas HIV infection did not (HR, 1.69; P = .20). After controlling for pretransplantation CD4(+) cell count and HIV RNA levels, the only significant predictor of mortality in the HIV-infected subjects was pretransplantation MELD score (HR, 1.2; P < .0001).
Pretransplantation mortality characteristics are similar between HIV-positive and HIV-negative candidates. Although lower CD4(+) cell counts and detectable levels of HIV RNA might be associated with a higher rate of pretransplantation mortality, baseline MELD score was the only significant independent predictor of pretransplantation mortality in HIV-infected liver transplant candidates.

    ABSTRACT: In the last three decades, the management of human immunodeficiency virus (HIV) has improved dramatically. The use of combination antiretroviral therapy (ART) has been successful at preventing death and the myriad infectious, malignant, and immune-mediated complications of HIV. Once considered to be a fatal disease, HIV is now considered by many to be a chronic disease; those affected may now live to experience complications of other coexistent diseases. Liver disease has been increasingly recognized as a leading cause of non-HIV/acquired immunodeficiency syndrome- (AIDS-) related morbidity and mortality in this population.Although liver transplantation offers the opportunity to prolong life, the transplant community has been slow to recognize the chronicity of HIV and potential for transplantation within this population. The experience with liver transplantation in HIV-positive patients is evolving and successful outcomes have been observed when specific criteria are used to select candidates.

    ABSTRACT: With the successful introduction of combined antiretroviral therapy (cART), human immunodeficiency virus (HIV) is now regarded as a chronic illness with excellent long-term outcomes. However, chronic exposure to viral etiologies (ie, chronic hepatitis B and hepatitis C) and drug-induced toxicity secondary to cART have resulted in increasing rates of mortality and morbidity due to end-stage liver disease. HIV disease is no longer considered an absolute contraindication to liver transplantation (LT) by most transplant centers worldwide. Because the burden of liver disease in this cohort is likely to increase, this review addresses the key etiologies and the management strategies available for HIV-positive patients undergoing LT.
