OBJECTIVE: To determine if low levels of serum vitamin A and beta-carotene
are present in pregnant women with human immunodeficiency virus-1 (HIV-1)
infection. METHODS: Serum concentrations of vitamin A and beta-carotene
were measured in 74 pregnant women seropositive for HIV-1 infection (17
with CD4 count below 200 cells/microliter) and in 148 pregnant seronegative
controls in the first trimester. Comparisons were made between groups
stratified by CD4 count. RESULTS: Compared with controls, women with
HIV-1 infection and CD4 count below 200 cells/microliter exhibited 37%
lower mean serum vitamin A levels (0.820 versus 1.308 micromol/L, P < .001)
and 37% lower mean serum beta-carotene levels (1.486 versus 2.362 micromol/L,
P < .001). Mean maternal age, parity, gestational age, hemoglobin
levels, and body mass index at entry into the study did not differ significantly
between the control and HIV-1 infection groups. In addition, serum vitamin
A levels correlated significantly with the percentage of CD4 lymphocytes
(r = 0.589, P < .001), CD4 count (r = 0.772, P < .001), and CD4
to CD8 ratio (r = 0.593, P < .001). Serum beta-carotene levels correlated
with the percentage of CD4 lymphocytes (r = 0.407, P < .001), CD4
count (r = 0.614, P < .001), and CD4 to CD8 ratio (r = 0.434, P < .001).
CONCLUSION: Compared with levels in uninfected women, serum vitamin A
and beta-carotene are decreased in HIV-1-infected pregnant women in the
first trimester with CD4 counts lower than 200 cells/microliter. These
micronutrient concentrations also correlate with CD4 count.
