Plasma viremia and virus phenotype are correlates of disease progression in vertically human immunodeficiency virus type 1-infected children

Abstract

Clinical symptoms, the most dramatic being reduction in the number of CD4 lymphocytes, and the highest plasma viremia levels were observed in the children in whom fast replicating, highly cytopathic SI variants were isolated. These data extend the virologic characterization of vertically HIV-1 infected children and suggest that both the plasma viremia levels and phenotype of primary isolates are viral correlates of disease progression in vertically infected children.
