 AB    The purpose of this study was to determine whether soluble CD8 (sCD8) in
       serum of perinatally human immunodeficiency virus 1 (HIV-1)-infected
       children during the first year of life differs from that of
       HIV-1-uninfected control children. Soluble CD8 concentrations in stored
       plasma and serum samples of children of HIV-1-infected and uninfected
       mothers were determined using a sandwich immune assay. In the first
       month of life significantly greater concentrations of sCD8 occurred in
       12 HIV-1-infected infants than in 9 uninfected infants born to infected
       mothers (mean = 1054, SD 540 vs. 589, SD 370 units/ml, P < 0.05),
       although the CD8+ T cell proportions were not different (21.7 vs. 21.1,
       P > 0.5). The difference in sCD8 concentrations was most pronounced in 8
       infants who were HIV-1 culture positive on initial testing in the first
       week of life compared with the remaining 4 patients when virus was first
       detected on subsequent analysis (mean = 1315, SD 446 vs. 529, SD 231
       units/ml, P < 0.01). The concentration of sCD8 was also greater in 26
       HIV-1-infected children than in either 26 uninfected children born to
       infected mothers or 25 seronegative children during the first year of
       life (mean = 1268, SD 529 vs. 630, SD 290 vs. 553, SD 315 units/ml, P <
       0.05). Early and persistent elevation in sCD8 probably reflects immune
       activation resulting from HIV-1 infection. The occurrence of this
       increase in the neonatal period may reflect prenatal viral transmission,
       a higher viral inoculum or coinfection with other agents stimulating
       immune activation.
