Five patients with Pneumocystis carinii pneumonia after heart
transplantation are reported. Four had severe clinical symptoms, whereas 1
was asymptomatic. Mechanical ventilatory support was necessary in 1 because
of respiratory distress. Pneumocystis carinii infection developed in 4
patients within the first 4 postoperative months, and 1 patient had
clinical disease 1 year after transplantation with a recurrence 9 months
later. All were treated with trimethoprim- sulfamethoxazole either orally
or intravenously (10 to 20 mg.kg-1.day-1 of trimethoprim). All patients
recovered from infection and received the same drug prophylactically for 2
to 20 months after the infection. All patients are doing well after
Pneumocystis carinii infection except 1 who died after an acute myocardial
infarction 4 years after infection. We conclude that
trimethoprim-sulfamethoxazole is an effective agent for the treatment of
Pneumocystis carinii pneumonia after heart transplantation.
