Lifelong Prophylaxis With Trimethoprim-Sulfamethoxazole for Prevention of Outbreak of Pneumocystis jirovecii Pneumonia in Kidney Transplant Recipients

Outbreaks of Pneumocystis jirovecii pneumonia (PCP) in kidney transplant recipients are frequently reported worldwide. However, the general guidelines propose only short-term prophylaxis with trimethoprim-sulfamethoxazole after kidney transplantation. We experienced 3 PCP outbreaks in the last 10 years despite providing the recommended prophylaxis. The purpose of this study was to find a prophylaxis regimen that could successfully prevent future PCP outbreaks in immunosuppressed kidney transplant recipients
