[Pneumocystis pneumonia in 3 non HIV patients]

We report 3 cases of pneumocystis pneumonia (PCP) in 2 female and 1 male patients (mean age=50 years) free of human immunodeficiency virus (HIV) infection. One female patient presented with breast neoplasm the other with Wegener's granulomatosis, the male patient with lymphoma. All patients were taking immunosuppressive treatment at the time of infection. Persistent cough, dyspnea, and severe hypoxemia were the most characteristic clinical signs. All patients presented with lymphopenia (average CD4-cell count=275/mm3), two with hypoalbuminemia, and one with renal failure. In all cases, the microscopic analysis of bronchoalveolar lavage was used to establish the diagnosis. All patients were treated with trimethoprim and sulfamethoxazole and a tapering dose of corticosteroids. Outcome was favorable for 1 patient, 1 was transferred to the intensive care unit for acute respiratory failure, and 1 died.
