Human immunodeficiency virus infection in children hospitalised with tuberculosis.

ABSTRACT

The impact of HIV infection on clinical presentation and outcome of tuberculosis (TB) was studied in children hospitalised at the Brooklyn Hospital for Chest Diseases (BCH), Cape Town over the 2-year period January 1998 to December 1999. Clinical data were extracted from a prospectively compiled patient register. Of 261 children with TB, 114 (median age 24 mths) were not HIV-infected and 36 (median age 23 mths) were HIV-infected. The HIV status of 111 children (median age 37 mths) was not determined. Pulmonary TB with or without extrapulmonary TB occurred in 97 (85%) children who were not HIV-infected, 35 (97%) HIV-infected children and 87 (78%) of those not tested (p = 0.025). A tuberculin reaction > or = 15 mm was elicited in ten (31%) of 32 HIV-infected children, 76 (72%) of 106 non-HIV-infected and 62 (71%) of those not tested (p < 0.001). Mycobacterium tuberculosis was cultured from 116 (49%) of 238 children and drug sensitivity was evaluated in 79. Nine isolates (11%) were resistant to isoniazid (INH) and 11 (14%) to INH and rifampicin (RMP). Two HIV-infected children treated previously in BCH for drug-sensitive TB were re-admitted with INH and RMP resistance. Two (2%) non-HIV-infected children, six (17%) HIV-infected children and one (1%) child with undetermined HIV status died (p < 0.001).
