TUBERCULOSIS IN IMMUNOSUPPESSED PATIENTS
1979
Abstract 11 patients who developed tuberculosis while on long-term immunosuppressive-drug therapy are described. The indications for immunosuppressive therapy were varied, but all patients received high doses of corticosteroids with azathioprine in addition in 2 cases and chlorambucil in a third. The diagnosis was delayed in all cases because of suppression of symptoms, so that 4 patients died, 3 directly as a result of tuberculosis. 3 of the remaining patients were critically ill at the time of diagnosis but recovered with antituberculosis chemotherapy; whereas the other 4, although not critically ill, had advanced cavitated pulmonary tuberculosis with miliary spread in one case. A clear policy of investigation and, if indicated, chemoprophylaxis is necessary for all patients in whom long-term immunosuppressive therapy, especially with prednisolone, is contemplated. A high index of suspicion for tuberculosis must be maintained with regular clinical and radiological review.
