Description:

Objective

In resource-limited settings without safe alternatives to breastfeeding, the WHO recommends exclusive breastfeeding and antiretroviral (ARV) prophylaxis. Given the high prevalence of anemia among HIV-infected women, mothers and their infants (via fetal iron accretion) may be at risk of iron deficiency. We assessed the effects of maternal micronutrient-fortified lipid-based nutrient supplements (LNS) and maternal ARV treatment or infant ARV prophylaxis on maternal and infant iron status during exclusive breastfeeding from birth to 24 weeks.

Methods

The Breastfeeding, Antiretrovirals, and Nutrition Study was a randomized controlled trial conducted in Lilongwe, Malawi from 2004-2010. HIV-infected mothers (CD4>200 cells/ul) and their infants were randomly assigned to 28-week interventions: maternal-LNS/maternal-ARV (n=424), maternal-LNS/infant-ARV (n=426), maternal-LNS (n=334), maternal-ARV (n=425), infant-ARV (n=426), or control (n=334). Longitudinal models tested intervention effects on hemoglobin (Hb). In a subsample (n=537) with multiple iron indicators, intervention effects on Hb, transferrin receptors (TfR) and ferritin were tested with linear and Poisson regression.

Results

In longitudinal models, LNS effects on maternal and infant Hb were minimal. In subsample mothers, maternal ARVs were associated with tissue iron depletion (TfR>8.3 mg/L) (Risk ratio (RR): 3.1, p<0.01), but not in ARV-treated mothers receiving LNS (p=0.17). LNS without ARVs, was not associated with iron deficiency or anemia (p>0.1). In subsample infants, interventions were not associated with impaired iron status (all p-values>0.1).

Conclusions

Maternal ARV treatment with protease inhibitors is associated with maternal tissue iron depletion; but LNS mitigates adverse effects. ARVs do not appear to influence infant iron status; however, extended use needs to be evaluated.
