Slower response to treatment of iron-deficiency anaemia in pregnant women infected with HIV: a prospective cohort study.

Antenatal anaemia is associated with increased peripartum transfusion requirement in South Africa. We studied whether HIV was associated with the response to treatment of iron-deficiency anaemia. Prospective cohort study. Hospital-based antenatal anaemia clinic in South Africa. Equal-sized cohorts of pregnant women testing positive for HIV (HIV+) and testing negative for HIV (HIV-) with iron-deficiency anaemia. Haemoglobin trajectories of women with confirmed iron-deficiency anaemia (ferritin < 50 ng/ml) were estimated from the initiation of iron supplementation using mixed-effects modelling, adjusted for baseline HIV status, ferritin level, maternal and gestational ages and time-varying iron supplementation. Haemoglobin trajectories. Of 469 women enrolled, 51% were HIV+, 90% of whom were on antiretroviral therapy (with a mean CD4+ lymphocyte count of 403 cells/mm Compared with women who were HIV-, women who were HIV+ with iron-deficiency anaemia had slower but successful haemoglobin recovery with iron therapy. Earlier effective management of iron deficiency could reduce the incidence of peripartum blood transfusion. Among pregnant women with iron-deficiency anaemia in South Africa, HIV slows haemoglobin recovery in response to oral iron therapy.
