The activities of HIV-specific cytotoxic T lymphocytes (CTLs) were evaluated in 10 HIV-infected children, born to infected mothers who did not receive AZT during pregnancy. CTL activities were present as early as 4 months of age. The five children that progressed to AIDS before 1 year of age had reduced in vivo and in vitro CTL activities, when compared with children who remained AIDS free after 1 year of age. The latter children had weak in vivo activated CTL responses but strong memory CTLs. No relation was found between viral load, lymphocyte populations, and CTL responses between birth and 6 months of age. Between 7 and 12 months old, children with broader in vitro activated CTLs had higher absolute numbers of CD4+ and CD8+ T lymphocytes and lower plasma viral load. These data support a beneficial role of CTLs in pediatric HIV infection.
