In this study, we sought to examine whether the administration of multivitamins excluding vitamin A, multivitamins including vitamin A, or vitamin A alone would reduce the risk of perinatal transmission of HIV and slow the rate of disease progression in a group of pregnant HIV infected women. We also examined the efficacy of the supplements on pregnancy outcomes, and risks of maternal and child morbidity and wasting.

A monooxygenase that catalyzes the conversion of BETA-CAROTENE into two molecules of RETINAL. It was formerly characterized as EC 22.214.171.124 and EC 126.96.36.199.
A carotenoid produced in most carotenogenic organisms. It is one of several sequentially synthesized molecules that are precursors to BETA CAROTENE.
A carotenoid that is a precursor of VITAMIN A. It is administered to reduce the severity of photosensitivity reactions in patients with erythropoietic protoporphyria (PORPHYRIA, ERYTHROPOIETIC). (From Reynolds JEF(Ed): Martindale: The Extra Pharmacopoeia (electronic version). Micromedex, Inc, Engewood, CO, 1995.)
Mono-hydroxylated xanthophylls formed from the hydroxylation of BETA-CAROTENE. Isomers include: beta-cryptoxanthin, alpha-cryptoxanthin, and zeinoxanthin. The alpha- and beta-cryptoxanthin are provitamin A precursors.
A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
