To date, the acquired immunodeficiency syndrome (AIDS) has been identified in over 50 children in the US, including those with associated hemophilia, high-risk environmental factors (Haitian background, parental intravenous drug abuse, or prostitution), and blood transfusions. The evaluation of an infant or young child in whom AIDS is suspected requires exclusion of congenital disorders of immune function. A specific test is not currently available, but inclusion criteria for childhood AIDS have been developed. The diseases accepted as indicative of underlying cellular immunodeficiency children are the same as those used in defining AIDS in adults, with the exclusion of congenital infections such as toxoplasmosis or herpes simplex virus infection in the 1st month of life or cytomegalovirus infection in the 1st 6 months of life. Specific conditions that must be excluded in children are primary immunodeficiency diseases (e.g., DiGeorge syndrome, Wiskott-Aldrich syndrome, ataxia-telangiectasia, neutrophil function abnormality) and secondary immuno-deficiency associated with immunosuppressive therapy, lymphoreticular malignancy, or starvation. Almost all young children with AIDS have hepatosplenomegaly, interstitial pneumonitis, and poor growth. The average age of 36 US child AIDS victims studied in detail was 5 months at presentation with findings suggestive of severe immunodeficiency. Mucocutaneous candidiasis was present in 75% of these 36 children, and Pneumocystis carinii and cytomegalovirus were each isolated from 30% of cases. Normal T4:T8 ratios occur in about 15% of pediatric AIDS cases. Laboratory evidence of polyclonal hypergammaglobulinemia generally supports the AIDS diagnosis. Recurrent infection and malnutrition are major problems in the clinical management of child AIDS patients.
