Abstract

Objectives: Pneumocystis jiroveci pneumonia is a rare but lethal complication in renal transplant recipients. Dose reduction of immunosuppressive agents in such situations is recommended, but its quantity and safety are unclear. Materials and Methods: From January 2001 to January 2011, twenty of one thousand forty-six renal transplant recipients in a single center developed Pneumocystis jiroveci pneumonia, which was diagnosed by the Giemsa and Gomori methenamine silver stains from a specimen of bronchoalveolar lavage. Results: We found that timing of the first immunosuppressant reduction of the Pneumocystis jiroveci pneumonia survivor (mean, 1.4 days after admission) was significantly earlier than that of the deceased patient (mean, 5.1 days after admission). Logistic regression analysis indicated that for those whose immuno - suppressants were reduced more aggressively (either 1 of the immunosuppressants was reduced by more than 50% within 2 days of hospitalization) were significantly more likely to survive (mortality risk, OR, 0.074 [95% CI, 0.01-0.84]; P =.035). In addition, none of the survivors developed acute rejection or allograft necrosis during a mean follow-up of 2 years. Conclusions: Dosage reduction of immuno - suppressive agents in renal transplant recipients with Pneumocystis jiroveci pneumonia should be prompt and sufficient. Aggressive immuno - suppressant dosage reduction is safe in such circumstance and is associated with minimal risk of in-hospital and long-term acute allograft rejection.
