ABSTRACT
Rejection rates in HIV-infected kidney transplant (KTx) recipients are higher than HIV-negative recipients. Immunosuppression and highly active antiretroviral therapy (HAART) protocols vary with potentially significant drug-drug interactions, likely influencing outcomes. This is an IRB-approved, single-center, retrospective study of adult HIV-infected KTx patients between 5/2009 and 12/2014 with 3-year follow-up, excluding antibody-depleting induction. A total of 42 patients were included; median age was 52 years, 81% male, 50% African American, 29% Hispanic, 17% Caucasian. The most common renal failure etiology was hypertensive nephrosclerosis (50%) with 5.8 median years of pre-transplant dialysis. All patients received IL-2 receptor antagonist, were maintained on tacrolimus (76%) or cyclosporine (17%), and 40% received ritonavir-boosted PI-based HAART (rtv+) regimen. Patient and graft survival at 3 years were 93% and 90%. At 1-, 2-, and 3-year time points, median serum creatinine was 1.49, 1.35, and 1.67; treated biopsy-proven rejection was 38%, 38%, and 40.5%; and 92% of episodes were acute rejection. At these time points, rejection rates were significantly higher with boosted PI HAART regimens compared to other HAART regimens, 59% vs 24% (P = 0.029), 59% vs 24% (P = 0.029), and 68% vs 24% (P = 0.01). Despite higher rejection rates, HIV-infected KTx recipients have reasonable outcomes. Given significantly higher rejection rates using rtv+ regimens, alternative HAART regimens should be considered prior to transplantation.
