Solid organ transplant (SOT) recipients are at risk for Pneumocystis pneumonia (PCP), especially in the first year post transplant. Although trimethoprim-sulfamethoxazole (TMP-SMX) prophylaxis substantially decreases this risk, there is little data or consensus on optimal duration of prophylaxis. Consequently, there is lack of standardization of prophylaxis duration (3 months to lifelong, depending on organ group) in SOT programs. ⋯ Our experience with late PCP cases in lung transplant recipients receiving only 1 year of prophylaxis lends support to prolonged PCP prophylaxis in this group. Given the number of patients who had experienced an acute rejection episode or CMV disease preceding PCP in non-lung SOT recipients, consideration should be given to re-institution of PCP prophylaxis for a period of time after these events in kidney, kidney/pancreas, and liver transplant recipients.
