Lymphocyte changes in pregnancy: a comparison of the human immunodeficiency virus infected and non-infected women.

The aim of this study was to assess cellular immunological changes in HIV infected and non-infected normal pregnancies. This was a cross-sectional study of women in the three trimesters of pregnancy and the postpartum period. All participants were asymptomatic. This study showed that absolute numbers of CD4 counts in the HIV infected group were significantly lower than that in the non-infected group, for all periods of gestation studied. The CD8 counts were found to increase postdelivery and may have clinical significance in relation to mother to child transmission. This needs further study with a larger sample size and a longitudinal design method of study.
