title: [Pneumonia caused by Pneumocystis carinii in immunodepressed patients: clinical picture, treatment, and prognosis].
abstract: Pneumocystis carinii pneumonia is frequent in patients with cellular immunity impairments, specially those with AIDS. We communicate our experience in 20 patients (15 with AIDS) with Pneumocystis carinii pneumonia confirmed by the finding of trophozoites or cysts. Clinical manifestations were cough in 75% of cases, dyspnea in 70% and fever in 65%. Eighty five percent of cases had diffuse reticular and nodular radiological densities. Nineteen patients had an increased alveolar-arterial O2 gradient. Nineteen patients were treated with trimethropim-sulphamethoxazole (TMP-SMX) and 4 with pentamidine isethionate (1 due to previous allergy and 3 due to poor response to TMP-SMX). Three patients died during the acute episode. Of the survivors, 13 died within 2 to 44 months later (14.5 +/- 12 months). It is concluded that AIDS is the most frequent underlying condition in patients with Pneumocysts carinii pneumonia and that long term survival is low.
