AB The aims of the present study were to analyze the impact of perinatal
human immunodeficiency virus (HIV)-1 infection on lymphocyte maturation
in children, to determine the expression of activation markers on CD8+
cells, and to define predictors of survival in HIV-infected children.
Seventy-one children presenting HIV-related symptoms were included in
the study; 29 were less than 2 y old and 42 were 2 to 12 y of age.
Results were compared with those obtained in normal children of a
similar age. In HIV-infected children the proportion of CD4+ and
CD8+CD45RA+ cells was significantly decreased, whereas that of CD8+,
CD8+CD38+, and CD8+CD45RO+ cells was strikingly increased compared with
controls. In children less than 2 y old the absolute number of CD4+ and
CD8+CD45RA+ cells decreased, and the number of CD8+CD45RO+ cells
increased significantly, whereas the number of CD8+ and CD8+CD38+ cells
did not change. The absolute number of CD4+ T cells declined with age
both among controls and among HIV-infected children. In contrast, the
absolute number of CD8+ cells and CD8 subsets decreased with age only in
controls but not in infected children. In HIV-1-infected children the
expression of the CD38 and CD45RO markers on CD8+ cells was
significantly correlated, indicating that these were activated cells.
The survival of less than 2-y-old children with AIDS symptoms was
positively correlated with the total number of CD8 cells and CD8+CD38+
cells at time of entry into the study.(ABSTRACT TRUNCATED AT 250 WORDS)
