AB OBJECTIVE: To describe the influence of pregnancy on immunological
marker paths and progression of HIV-infected women. DESIGN: Analysis of
prospectively collected immunological and clinical data collected on 145
women reviewed at the City Hospital, Edinburgh, between 1985 and 1992
using a two-level random-effects model that allows for within- and
between-patient variance. RESULTS: There were differences between the
marker paths of women according to risk activity; women who had acquired
HIV via injecting drug use (in addition to heterosexual intercourse) had
a higher level of absolute CD4 cells, CD4% and total lymphocytes at
seroconversion than those who had acquired HIV via heterosexual
intercourse alone; however, immunological markers declined more steeply
after seroconversion. There was no evidence that pregnancy, either
before or after HIV seroconversion had an adverse effect on marker paths
of HIV disease. There was a significant association between pregnancy
after HIV seroconversion and post-pregnancy changes in immunological
markers: an increase in the CD4% and a decrease in CD8%. However,
causality cannot be implied as pregnancy itself may be associated with
considerable lifestyle changes. During pregnancy the total white blood
count rose due to an increase in the number of granulocytes, whereas the
total lymphocyte numbers fell. The absolute CD4 lymphocyte subset counts
fell progressively but the effect was due to the fall in the total
lymphocyte counts, there being no influence of pregnancy on either CD4%
or CD8%. CONCLUSIONS: In asymptomatic HIV infection, changes in the
absolute levels of CD4 and CD8 lymphocyte counts are primarily related
to changes in the other components of the white cell count because there
were no changes in CD4% and CD8%. Pregnancy itself has no adverse effect
on immunological markers of HIV.
