Tuberculosis after corticosteroid therapy.

Abstract

Fourteen episodes of reactivation of tuberculosis after corticosteroid administration are reported. In most a disease impairing the host defences was present and four were taking additional immunosuppressants. The most common presenting symptoms were productive cough and malaise. Bacteriological diagnosis required bronchoscopy in three cases. Response to antituberculosis therapy was good. Five of the 14 episodes manifested dissemination of pulmonary tuberculosis with four occurring in patients receiving high-dose corticosteroids and other immunosuppressants. No prolongation of sputum conversion time was noted in the patients. The published effects of corticosteroids on the tuberculous state are reviewed. Because INH administration may cause liver damage in a small minority of patients, a reassessment is required of the need for INH chemoprophylaxis when corticosteroids are used in patients with healed tuberculosis.
