HIGH-DOSE CORTICOSTEROIDS AS ADJUNCT THERAPY IN SEVEREPNEUMOCYSTIS CARINIIPNEUMONIA

Abstract

Three patients with severe Pneumocystis carinii pneumonia and acquired immunodeficiency syndrome, not responding to specific therapy with trimethoprim/sulfamethoxazole, were treated with a 24-hour course of high-dose methylprednisolone. Rapid improvements in the clinical status and the chest X-rays were detected. In two of the patients, in whom lung biopsy was performed before initiation of corticosteroids, an intense interstitial mononuclear cell infiltrate was seen. In the one patient who had lung biopsy after corticosteroid therapy, a scanty amount of mononuclear cells was demonstrated in the interstitium. Our experience suggests that corticosteroids may be useful as adjunctive agents in the treatment of severe P. carinii pneumonia not responding to specific anti-Pneumocystis therapy. This may be a result of inhibition of mononuclear cell accumulation within the lung by the steroid therapy.
