AB OBJECTIVE: To determine whether maternal transmission of human
immunodeficiency virus (HIV) is correlated with increased quantities of
HIV, decreased frequencies of CD4+ T cells, or increased levels of CD8+
T cells in the transmitting mother. METHODS: Peripheral blood obtained
from HIV-infected women at different times during pregnancy was used to
measure quantitative cell-associated HIV-1 and CD3+CD4+ and CD3+CD8+
proportions; the plasma was used to perform measurements of quantitative
viremia by culture and subsequently to measure quantitative HIV-1
ribonucleic acid levels. These measurements were analyzed with respect
to their association with HIV transmission to the baby, which occurred
in one fourth of the cases. The children were also studied to determine
whether HIV-1 was detected near birth or not until 1 to 8 weeks of life.
RESULTS: Increased clonal frequencies of HIV-1-infected peripheral blood
mononuclear cells were found in mothers of infected children; fivefold
fewer cells were required for a positive culture result (median cell
numbers of 10(4.5) vs 10(5.2); p = 0.008). Higher frequencies of
infected cells were seen in mothers of babies with evidence of infection
at birth than in mothers of infected babies without evidence of
infection at birth (p < 0.05). Plasma viremia was measured in 10% of
cultures without regard to whether the mothers transmitted virus to
their babies. Increased levels of ribonucleic acid as detected by the
branched-chain DNA method were measurable more often (45% vs 17%) in the
mothers of infected children than in mothers of uninfected children.
Proportions of CD4+ and CD8+ T cells were indistinguishable in these two
groups of women. CONCLUSIONS: Increased viremia was present in mothers
who transmitted HIV to their offspring. This variable could be used to
select women at highest risk of transmitting HIV to their offspring for
treatment to decrease the HIV burden five-fold.
