Pneumocystis carinii pneumonia in heart transplant recipients.
Seven cases of Pneumocystis carinii pneumonia (PCP) (two in 1988, three in 1989, one in 1990 and one in 1991) have been observed in a group of 241 heart transplant recipients transplanted in Pavia, Italy, from November 1985 through December 1991. Median time to onset of symptoms was 100 days after transplantation (range 59-333 days). Diagnosis was achieved in all patients by cytological examination of bronchoalveolar lavage (BAL) fluid and/or transbronchial biopsy. Clinical and roentgenographic features were remarkably similar in all PCP-affected heart transplant recipients. A dry, persistent hacking cough associated with dyspnoea was consistently observed. Fever ranged from 37.6 to 39.4 degrees C, median leukocyte count and median arterial oxygen saturation (SaO2) values were 7,300/mm3 (range 3,000-16,000/mm3) and 61% (range 49.3-93%), respectively. Median CD4+ count at the onset of symptoms was 211/mm3 (range 28-739/mm3). The only patient experiencing a recurrence of PCP had a CD4+ cell count of 28/mm3 at the end of treatment with trimethoprim-sulfamethoxazole (TMP-SMX). In all patients human cytomegalovirus was isolated from BAL fluids; however, treatment with TMP-SMX alone (20 mg/kg/day of TMP) was consistently followed by a complete recovery.
