Bronchiolitis obliterans organizing pneumonia associated with Pneumocystis jiroveci infection in orthotopic liver transplantation.

We report a patient who presented 6 months after orthotopic liver transplantation (OLT) with fever, dyspnea, and pulmonary infiltrates with biopsy-confirmed Pneumocystis jiroveci infection associated with a process of bronchiolitis obliterans organizing pneumonia (BOOP). We present this second case of BOOP associated with P. carinii pneumonia after OLT to highlight the risk of such disease combination in all transplant patients as well as discuss the protective effect of post-transplant prednisolone with trimethoprim-sulfamethoxazole prophylaxis and the possible duration of prophylaxis.
