Experience with a six-month regimen of Pneumocystis pneumonia prophylaxis in 122 HIV-positive kidney transplant recipients.

Anti-Pneumocystis pneumonia (PCP) prophylaxis is recommended for 3 to 6 months post-transplant, in HIV-negative kidney transplant recipients. For HIV-positive kidney transplant recipients, there is no definite duration of primary prophylaxis and is often prescribed life-long. The objective of this study is to determine the incidence of PCP in HIV-positive recipients who received 6 months of prophylaxis with trimethoprim-sulfamethoxazole or an alternative agent. One hundred and twenty-two HIV-positive recipients received a kidney transplant from 2001 to 2017 at Hahnemann University Hospital. Most patients received induction immunosuppression with an IL-2 receptor antagonist, with or without intravenous immunoglobulin. Only one patient received anti-thymocyte globulin. Maintenance immunosuppression included a calcineurin-inhibitor (tacrolimus or cyclosporine), an antiproliferative agent (mycophenolate or sirolimus), and prednisone. Mean CD4 cell count was 461 ± 127 cells/uL prior to transplant and 463 ± 229 cells/uL at 6 to 12 months after transplant. None of the recipients developed PCP after a median follow-up of 2.88 years (IQR 1.16-4.87). Based on our observation, a 6-month regimen of PCP prophylaxis may be sufficient among HIV-positive recipients, similar to those without HIV infection.
