Variability of Pneumocystis jirovecii prophylaxis use among pediatric solid organ transplant providers

Abstract

Pneumocystis jirovecii pneumonia (PJP) prophylaxis after pediatric solid organ transplant (SOT) is routinely recommended, but practice varies. Online survey was sent in 2018 to 707 members of the International Pediatric Transplant Association. A total of 105 responded, representing 47 institutions in 18 countries consisting of transplant physicians (66%), transplant surgeons (19%), nurse practitioners (6%), infectious disease physicians (5%), or pharmacists (4%). PJP prophylaxis was reported by 88%, while 12% did not routinely give prophylaxis. The majority not using PJP prophylaxis performed renal transplants (67%) citing low incidence of PJP (62%). Trimethoprim/sulfamethoxazole was first‐line agent (95%). PJP prophylaxis for 4‐6 months was the most frequent duration following kidney (48%, 27/56), liver (42%, 13/31), and heart (40%, 10/25) transplant. Abdominal multivisceral providers equally gave 10‐12 months (47%) or lifelong (47%); most lung transplant providers gave lifelong prophylaxis (85%). Across all organs, 21% provided lifetime prophylaxis. After completion of prophylaxis, 32% do not restart for any reason; majority of the rest would restart for treatment of acute graft rejection. 83% reported no PJP cases in the prior 12 months; 14% reporting 1‐5 infections. Only 3% reported a case of PJP infection on prophylaxis; none in SOT. PJP prophylaxis is routinely provided to pediatric SOT patients though practice and duration vary by center and organ type. Durations of 4‐6 months were most common for renal, liver, and heart transplant recipients, while 10‐12 months or lifelong prophylaxis were commonly reported for abdominal multivisceral recipients and most lung transplant recipients are given lifelong prophylaxis.
