Sustained Viral Suppression and Immune Recovery in HIV Type 1--Infected Children after 4 Years of Highly Active Antiretroviral Therapy

We report the data from a long-term study of 31 human immunodeficiency virus type 1 (HIV-1)-infected children who were treated with highly active antiretroviral therapy. A high proportion of the children had undetectable HIV-1 RNA levels. CD4+ T cell counts recovered and remained stable. Adverse events were observed frequently but were mostly mild.
