*Purpose: Kidney transplantation in HIV positive recipients (HIV+) is the treatment of choice for renal failure in patients (P) who maintain CD4+ counts ≥ 200/mm3and undetectable HIV load on antiretroviral therapy. Long term outcomes data are limited. The aim of our study is to report long term clinical outcomes in HIV+ kidney transplant recipients.
*Methods: We conducted a single-center, retrospective review of all HIV+P transplanted from 10/2006 to 10/2019. Main outcomes assessed at 1, 3, and 5 years: patient survival, death-censored graft survival, renal function (eGFR), biopsy-proven acute rejection (BPAR), and infections requiring hospitalization during the first year. All patients received induction: Anti-thymocyte globulin (ATG) (3mg/kg), IL2R blockers, and methylprednisolone, and 7 also received rituximab (375 mg/m2); maintenance immunosuppression: tacrolimus, mycophenolate mofetil plus steroids except one patient received Belatacept.
*Results: A total of 80 HIV+P were transplanted during the study period, only one was a re-transplant. 53 (66%) males, 27 (34%) females with a median age of 50 years old (32-75); 62 (78%) African-American, 12 (15%) Caucasian, 3 (4%) Hispanic and 3 (4%) other race; 19% received living donor and 81% received deceased donor organs. cPRA was < 40 % in 71 (89%), between 40-79% in 7 (8%) and >80% in 2 (3%) HIV+P; median CD4+ count at transplant was 492/mm3 (205-1448). Median follow up was 997 days (4-2794). 16% had delayed graft function. 15 HIV+P had BPAR at 1 year (19%): 67% T cell, 29% mixed and 4% antibody mediated rejection (AMR); and 9 HIV+P (11%) thereafter (up to 8 years) with 37.5% T cell and mixed rejection and 25% AMR. Out of 65 patients, 18 (27%) required admission during the first-year secondary to infection. HIV+P survival was 93%, 85% and 84%, and death censored graft survival was 92%, 86% and 72% at 1, 3, and 5 years, respectively. Median serum creatinine was 1.5 (0.7-6.2), 1.5 (0.8-4.1), and 2.8 (0.6-15) mg/dl; and eGFR by CKD-EPI was 65 (10-120), 63 (15-110), and 53 (4-130) ml/min at 1 (N=57), 3 (N=41) and 5 (N=27) years, respectively without statistical significance when adjusted by donor type and rejection episodes.
*Conclusions: Our single center long term clinical outcomes in HIV+ P showed lower incidence of rejection than reported in the literature and equivalent patient and graft survival at 1, 3 and 5 years.
