Outcomes among HIV+ Tx continue to improve despite the established risk of rejection and calcineurin-nephrotoxicity. We sought to compare outcomes among HIV+ Tx vs. HIV- Tx receiving similar immunosuppression protocols.
Methods: Retrospective analysis of all HIV +/- Tx performed since 2011, receiving basiliximab + calcineurin inhibitor based immunosuppression. HIV+ Tx received IVIg as an additional induction agent. Clinical outcomes were assessed between the HIV+ Tx and HIV- Tx groups at 1 year post-transplant. All rejections were considered, including subclinical and borderline.
Results: In total, 39 patients were reviewed. Table 1 illustrates comparable recipient and donor characteristics. Donor age was younger among the HIV+ Tx, but KDRI was similar. Despite the potential for drug interactions among HIV+ Tx, tac troughs levels were comparable at all time points (Figure 1). Clinical post-Tx outcomes are comparable at all time points (Table 2). On follow-up biopsies, the incidence of mild fibrosis was more common among HIV + Tx (62% vs. 36%).
Conclusion: Immunosuppression protocols utilized among HIV- Tx can attain similar outcomes in HIV+ Tx. Standard markers of allograft function (i.e. eGFR) may not reflect degree of fibrosis on Biopsies in the HIV+ Tx. This may be reflected by the continuation of similar tac troughs throughout the post-Tx period..
