Summary

Although the pathogenesis of human immunodeficiency virus (HIV) infection and the general virologic and immunologic principles underlying the use of antiretroviral therapy are similar for all HIV-infected persons, there are unique considerations needed for HIV-infected infants, children, and adolescents, including a) acquisition of infection through perinatal exposure for many infected children; b) in utero exposure to zidovudine (ZDV) and other antiretroviral medications in many perinatally infected children; c) differences in diagnostic evaluation in perinatal infection; d) differences in immunologic markers (e.g., CD4⁺ T-lymphocyte count) in young children; e) changes in pharmacokinetic parameters with age caused by the continuing development and maturation of organ systems involved in drug metabolism and clearance; f) differences in the clinical and virologic manifestations of perinatal HIV infection secondary to the occurrence of primary infection in growing, immunologically immature persons; and g) special considerations associated with adherence to treatment for children and adolescents.

This report addresses the pediatric-specific issues associated with antiretroviral treatment and provides guidelines to health-care providers caring for infected infants, children, and adolescents. * It is recognized that guidelines for antiretroviral use in pediatric patients are rapidly evolving. The Working Group on Antiretroviral Therapy and Medical Management of HIV-Infected Children will review new data on an ongoing basis and provide regular updates to the guidelines; the most recent information is available on the HIV/AIDS Treatment Information Service Website (http://www.hivatis.org).
