AB Immune function changes during pregnancy and human immunodeficiency
virus (HIV) infection. T helper function and phenotypes in HIV-infected
and -uninfected pregnant and postpartum women and nonpregnant uninfected
control women were studied. T helper function was assessed by
interleukin-2 (IL-2) production in vitro and three-color flow cytometry.
All uninfected nonpregnant subjects, 74% of uninfected pregnant
subjects, and only 54% of HIV-infected pregnant subjects responded to
all stimuli. All uninfected subjects 2-6 months postpartum had normal
function versus 27% of infected subjects (trend P < .001). Uninfected
pregnant subjects had reduced levels of CD4+CD45RA-RO+ (memory) and
elevated levels of CD4+CD45RA+RO- (naive) lymphocytes. Infected pregnant
subjects had elevated levels of memory, reduced levels of naive, and
increased levels of CD4+HLA-DR+CD38+ (activated) lymphocytes. Increased
CD4+DR+CD38+ cells correlated best with poor IL-2 function, HIV
infection, and being postpartum (R2 = .79). Thus, T helper function and
phenotypes are altered in pregnancy and return to baseline postpartum in
uninfected but not HIV-infected women.
