<p>
<bold>Background:</bold>
Little is known about the influence of antiretroviral therapy with or without micronutrient supplementation on the micronutrient concentrations of HIV-infected lactating women in resource-constrained settings. </p>
<p>
<bold>Objective:</bold>
We examined associations of highly active antiretroviral therapy (HAART) and lipid-based nutrient supplements (LNS) with concentrations of selected micronutrients in HIV-infected Malawian women at 24 wk postpartum.</p>
<p>
<bold>Methods:</bold>
Plasma micronutrient concentrations were measured in a subsample (
<italic>n</italic>
= 690) of Breastfeeding, Antiretrovirals, and Nutrition (BAN) study participants who were randomly assigned at delivery to receive HAART, LNS, HAART+LNS, or no HAART/no LNS (control). HAART consisted of protease inhibitor–based triple therapy. LNS (140 g/d) met energy and micronutrient requirements of lactation. Multivariable linear regression tested the association of HAART and LNS, plus their interaction, with micronutrient concentrations, controlling for season, baseline viral load, and baseline CD4 count. </p>
<p>
<bold>Results:</bold>
We found significant HAART by LNS interactions for folate (
<italic>P</italic>
= 0.051), vitamin B-12 (
<italic>P</italic>
< 0.001), and transferrin receptors (TfRs) (
<italic>P</italic>
= 0.085). HAART was associated with lower folate (with LNS: −27%,
<italic>P</italic>
< 0.001; without LNS: −12%,
<italic>P</italic>
= 0.040) and higher TfR concentrations (with LNS: +14%,
<italic>P</italic>
= 0.004; without LNS: +28%,
<italic>P</italic>
< 0.001), indicating iron deficiency. LNS increased folate (with HAART: +17%,
<italic>P</italic>
= 0.037; without HAART: +39%,
<italic>P</italic>
< 0.001) and decreased TfR concentrations (with HAART only: −12%,
<italic>P</italic>
= 0.023). HAART was associated with lower vitamin B-12 concentrations only when LNS was present (−18%,
<italic>P</italic>
= 0.001), whereas LNS increased vitamin B-12 only when no HAART was present (+27%,
<italic>P</italic>
< 0.001). HAART, but not LNS, was associated with higher retinol-binding protein (RBP; +10%,
<italic>P</italic>
= 0.007). We detected no association of HAART or LNS with selenium, ferritin, or hemoglobin. </p>
<p>
<bold>Conclusion:</bold>
The association of HAART with lower folate, iron deficiency, and higher RBP plus the attenuation of LNS effects on folate and vitamin B-12 when combined with HAART has implications for the health of lactating HIV-infected women taking HAART in prevention of mother-to-child transmission programs.

<p>The Breastfeeding, Antiretrovirals, and Nutrition (BAN) study was supported by grants from the Prevention Research Center’s Special Interest Project of the CDC (SIP 13-01 U48-CCU409660-09, SIP 26-04 U48-DP000059-01, and SIP 22-09 U48-DP001944-01), the Bill & Melinda Gates Foundation (OPP53107), the National Institute of Allergy and Infectious Diseases, the University of North Carolina Center for AIDS Research (P30-AI50410), the Carolina Population Center (R24 HD050924), the NIH Fogarty AIDS International Training and Research Program (DHHS/NIH/FIC 2-D43 TW001039), and Fogarty International Clinical Research Scholars (R24TW007988; the American Recovery and Reinvestment Act). The antiretrovirals used in the BAN study were donated by Abbott Laboratories, GlaxoSmithKline, Boehringer Ingelheim, Roche Pharmaceuticals, and Bristol-Myers Squibb. The Call to Action Prevention of Mother-to-Child Transmission Program, from which BAN mothers were recruited, was supported by the Elizabeth Glaser Pediatric AIDS Foundation, the United Nations Children’s Fund, the World Food Program, the Malawi Ministry of Health and Population, Johnson & Johnson, and the US Agency for International Development.</p>

= 690) of Breastfeeding, Antiretrovirals, and Nutrition (BAN) study participants who were randomly assigned at delivery to receive HAART, LNS, HAART+LNS, or no HAART/no LNS (control). HAART consisted of protease inhibitor–based triple therapy. LNS (140 g/d) met energy and micronutrient requirements of lactation. Multivariable linear regression tested the association of HAART and LNS, plus their interaction, with micronutrient concentrations, controlling for season, baseline viral load, and baseline CD4 count. </p>

<bold>Results:</bold>
We found significant HAART by LNS interactions for folate (
<italic>P</italic>
= 0.051), vitamin B-12 (
<italic>P</italic>
< 0.001), and transferrin receptors (TfRs) (
<italic>P</italic>
= 0.085). HAART was associated with lower folate (with LNS: −27%,
<italic>P</italic>
< 0.001; without LNS: −12%,
<italic>P</italic>
= 0.040) and higher TfR concentrations (with LNS: +14%,
<italic>P</italic>
= 0.004; without LNS: +28%,
<italic>P</italic>
< 0.001), indicating iron deficiency. LNS increased folate (with HAART: +17%,
<italic>P</italic>
= 0.037; without HAART: +39%,
<italic>P</italic>
< 0.001) and decreased TfR concentrations (with HAART only: −12%,
<italic>P</italic>
= 0.023). HAART was associated with lower vitamin B-12 concentrations only when LNS was present (−18%,
<italic>P</italic>
= 0.001), whereas LNS increased vitamin B-12 only when no HAART was present (+27%,
<italic>P</italic>
< 0.001). HAART, but not LNS, was associated with higher retinol-binding protein (RBP; +10%,
<italic>P</italic>
= 0.007). We detected no association of HAART or LNS with selenium, ferritin, or hemoglobin. </p>

<bold>Conclusion:</bold>
The association of HAART with lower folate, iron deficiency, and higher RBP plus the attenuation of LNS effects on folate and vitamin B-12 when combined with HAART has implications for the health of lactating HIV-infected women taking HAART in prevention of mother-to-child transmission programs.
