Clinical features of paediatric AIDS in Uganda.

A total of 177 children seen at two hospitals in Kampala are described who were strongly suspected of having acquired immunodeficiency syndrome (AIDS), either on clinical grounds or because they fulfilled the World Health Organization (WHO) case-definition criteria for diagnosis of paediatric AIDS. Blood was taken from the 177 children and 154 of their mothers and tested for antibody to human immunodeficiency virus (HIV) by an enzyme-linked immunoassay (ELISA). Altogether, 119 (67%) children were seropositive, but only 85 (71%) fulfilled the WHO case-definition criteria, and they were significantly older than the 34 who did not fulfil the criteria. A further 58 children were seronegative but fulfilled the WHO criteria. Of the 119 seropositive children, only 3 had a history of previous blood transfusion, but 103 (98%) of 105 mothers were HIV seropositive: consequently, their children were considered to have been infected in utero or perinatally. Thirteen (26%) of 49 mothers of seronegative children were seropositive. Eighty per cent of HIV-infected children were under 2 years of age at diagnosis and 23% died within 3 months of diagnosis. None of the parents was known to be an intravenous drug user, a prostitute or bisexual. The difficulty of accurate diagnosis of AIDS presents a major problem in Africa, as the WHO clinical case-definition criteria alone are clearly not adequate.
