We retrospectively studied the acute toxicity of corticosteroid therapy in 23 episodes of PCP occurring in the setting of AIDS and determined the incidence of HIV-related complications following these and 16 other contemporaneous episodes of AIDS-related PCP treated with antimicrobials alone. The mean duration of corticosteroid therapy was 5.4 days and the mean total dose was 660 mg of methylprednisolone. Cryptococcus neoformans and Listeria monocytogenes infection each occurred once within one month of therapy in corticosteroid-treated patients; no other noteworthy acute corticosteroid toxicity was noted. Since all patients with imminently lethal PCP received corticosteroids, we could not assess the effect of these agents on acute mortality. After six months the rates of new AIDS-related diagnoses and of post-hospitalization mortality were equivalent in the two groups. We also have critically reviewed the available literature regarding this use of corticosteroids.

Anti-tumor necrosis factor-alpha therapy, infliximab, has become an established effective therapy for Crohn's disease and rheumatoid arthritis. However, infliximab has been associated with various opportunistic pathogens such as tuberculosis, histoplasmosis, listeriosis, aspergillosis, and Pneumocystis jiroveci (carinii) pneumonia. We reviewed the FDA Adverse Event Reporting System for cases of Pneumocystis associated with infliximab use from January 1998 through December 2003. The database revealed 84 cases of PCP following infliximab therapy. Concomitant immunosuppressive medications included methotrexate, prednisone, azathioprine, 6-mercaptopurine, and cyclosporine. Mean time between infliximab infusion and onset of symptoms of pneumonia, when reported, was 21 days (+/-18 days; n=40). Twenty-three of the 84 (27%) patients died. The use of infliximab is associated with PCP infection. Further, the mortality rate for Pneumocystis following the use of infliximab is significant. The potential for severe disease, mortality, and often subtle presentation of these infections warrant close follow-up and careful monitoring after therapy.
