Lymphadenopathy in an inner-city population consisting principally of intravenous drug abusers with suspected acquired immunodeficiency syndrome.
Generalized lymphadenopathy in intravenous drug abusers (IVDAs) at risk for AIDS has not been well studied. We have retrospectively analyzed the results of lymph node biopsies obtained from 27 patients referred to the Infectious Diseases Service for evaluation of generalized lymphadenopathy and suspected AIDS during a recent 18-month period. Fourteen of the patients were heterosexual IVDAs, 7 were male homosexual IVDAs, and 6 were male homosexual non-IVDAs. All of the patients were residents of the Bronx, New York. Mycobacterium tuberculosis (TB) was the most frequent diagnosis established on lymph node biopsies from IVDAs, in 12 out of 21 (57%). Tuberculous adenitis was not diagnosed in the 6 non-IVDAs. All TB patients were febrile, 11 (91%) had lost weight, and 10 (84%) had an abnormal chest roentgenogram. The 5TU PPD skin test, however, was reactive in only 2 (16%) of 12 patients. Tuberculosis is important to consider in patient populations with exposure histories to both AIDS and TB. The alarmingly high prevalence of TB in this drug addict population emphasizes the importance of lymph node biopsies with acid-fast smears and mycobacterial cultures in symptomatic IVDAs. Preventive antituberculosis therapy for HIV-positive persons, especially IVDAs, with a history of positive tuberculin reactions or of recent household contact should be seriously considered.
