Pulmonary alveolar proteinosis (PAP) has been associated with the immunosuppressant sirolimus in transplant patients. PAP is a progressive lung disease characterized by the accumulation of surfactant-like material in the lungs leading to decreased pulmonary function with shortness of breath and cough as common symptoms. We report a rare case of sirolimus-associated PAP in a kidney transplant recipient with a history of end-stage renal disease secondary to haemolytic uraemic syndrome (HUS) and review of the literature. Discontinuation of sirolimus and initiation of tacrolimus led to resolution of PAP without recurrence of HUS.
