Pulmonary infections in renal transplantation patients treated with cyclosporine.

Seventeen cases of pneumonia occurring in renal transplantation patients treated with cyclosporine-prednisone immunosuppression were analyzed with regard to the organisms involved, time of occurrence after transplantation, clinical course, and radiographic findings. In a pattern similar to that encountered with conventional azathioprine-prednisone immunosuppression, opportunistic infections were most common in the period between 1 and 5 months after transplantation. All multiple-organism infections involved cytomegalovirus and carried a poor prognosis. No unexpected radiographic findings were noted.
