Abstract

The safety and activity of several antiretroviral agents are being evaluated for treatment of acquired immunodeficiency syndrome (AIDS) in infants and children. Intermittent oral and intravenous regimens and continuous intravenous infusion of the dideoxynucleoside, 3'-azido-3'-deoxythymidine (zidovudine, AZT), have been shown to be beneficial in improving neuro-developmental function and growth velocity in pediatric patients with AIDS. AZT, however, is limited by the associated development of neutropenia and anemia, which frequently necessitates transfusions. Another dideoxynucleoside, 2',3'-dideoxycytidine (ddC), also shows theoretical promise in the treatment of the pediatric AIDS population. This agent is not associated with the hematologic toxicity induced by AZT but does produce a painful sensory peripheral neuropathy. Sequential therapy with AZT and ddC may limit the toxic effects associated with the use of these drugs individually. Dideoxyinosine and soluble recombinant CD4 are two newer antiretroviral agents that are under investigation for the management of AIDS in infants and children. The activity of recombinant CD4 in preventing the transplacental transmission of human immunodeficiency virus is also being evaluated.
