Abstract:

Prophylaxis against Pneumocystis jirovecii pneumonia (PCP) is recommended for at least 4–12 months after solid organ transplant. In our center, renal transplant recipients receive only 1 month of post–transplant trimethoprim–sulfamethoxazole, which also may provide limited protection against Nocardia. We identified only 4 PCP cases and 4 Nocardia cases in 1352 patients receiving renal and renal–pancreas transplant from 2003 to 2009 at the University of Michigan Health System. Two PCP cases were identified <1 year after transplant, and 2 PCP cases were identified >1 year after transplant (gross attack rate 4/1352, 0.3%). Two Nocardia cases were identified <1 year after transplant, and 2 cases were identified >1 year after transplant. All identified cases received induction therapy (7 of 8 with anti–thymocyte globulin), whereas about one–half of all renal transplant patients received induction therapy at our institution. No patient was treated for rejection within 6 months of PCP; 2 of 4 patients with PCP had recent cytomegalovirus infection. All patients with PCP and 3 of 4 patients with Nocardia survived. The benefits of prolonged PCP prophylaxis should be weighed against the adverse events associated with prolonged use of antimicrobials.
