Abstract
Invasive bacterial infection in children infected with the human immunodeficiency virus (HIV) is common. South African data on this problem are limited. Over 1 year we prospectively studied 108 HIV-infected children hospitalized for 136 presumed infective episodes. Blood culture was positive in 24.8% of episodes. Streptococcus pneumoniae predominated (14/30 positive blood cultures); one-third of isolates showed resistance to penicillin. Acute lower respiratory tract infection accounted for 44% of clinical diagnoses, a bacterial cause being established for 23.8% of these. Age and stage of HIV infection did not influence the likelihood of a positive culture. A high proportion of presumed infective episodes requiring hospitalization of young HIV-infected children have a bacterial cause. Blood culture appears to be a useful method of obtaining the microbiological information required to focus antibiotic therapy.
