Background: The nutritional status of vitamin A in lactating mothers and infants is still not optimistic. Due to the dietary habits and dietary restrictions of postpartum customs in China, vitamin A supplementation has been advocated as a potential strategy to improve vitamin A status of lactating mothers with inadequate dietary vitamin A intake. Existing clinical trials are limited to single or double high-dose maternal administrations. However, in China, vitamin A supplements are readily available in the form of daily oral low-dose supplements, and the effect of these is unknown. This study aimed to evaluate the effects of daily oral low-dose vitamin A supplementation on the retinol levels in the serum and breast milk of lactating mothers and the health status of infants in China. Methods: Lactating mothers who met the inclusion criteria and planned to continue exclusive breastfeeding were randomly assigned to receive either daily oral vitamin A and D drops (one soft capsule of 1800 IU vitamin A and 600 IU vitamin D2), or a matching placebo for 2 months. Before and after the intervention, dietary intake was investigated by instant photography, and the retinol concentration in maternal serum and breast milk was determined by ultra-high performance liquid chromatography-tandem mass spectrometry. During the trial, the health status of infants was diagnosed by a paediatrician or reported by lactating mothers. A total of 245 participants completed the study, with 117 in the supplementation group and 128 in the control group. Results: After the 2-month intervention, maternal serum retinol concentrations increased in the supplementation group with no change in the control group. Although breast milk retinol concentrations decreased significantly in both groups, the decrease in the supplementation group was significantly lower than that in the control group. However, maternal vitamin A supplementation was not associated with a lower risk of infant febrile illness, respiratory tract infection, diarrhoea, and eczema. Conclusions: Daily oral low-dose vitamin A supplementation is helpful in improving maternal vitamin A status, despite having no effect on infant health status through breast milk.

Abstract Background: Vitamin A supplementation has been advocated as a potential strategy to improve the vitamin A status of lactating mothers and infants. In China, vitamin A supplements are readily available in the form of daily oral low doses. However, the existing clinical trials are limited to single or two high-dose maternal administration.Objective: We aimed to evaluate the effects of the daily oral low-dose vitamin A supplementation on the retinol levels in serum and breast milk of lactating mothers and the health status of infants in China.Methods: Lactating mothers who met the inclusion criteria and planned to continue exclusive breast-feeding were randomly assigned to receive either daily oral vitamin A and D drops (one soft capsule of 1800IU vitamin A and 600IU vitamin D2), or a matching placebo for 2 months. Before and after the intervention, the dietary intake was investigated by instant photography, and the retinol concentration in maternal serum and breast milk was determined by UPLC. During the trial, the health status of infants was diagnosed by pediatrician or reported by lactating mothers.Results: 245 participants completed the study with 117 in supplementation group and 128 in control group. After the 2-month intervention, maternal serum retinol concentration increased in supplementation group with no change in control group. Although breast milk retinol concentrations decreased significantly in both groups, the decrease in supplementation group was significantly less than that in the control group. However, maternal vitamin A supplementation was not associated with lower risks of infant febrile illness, respiratory tract infection, diarrhea and eczema respectively. Conclusion: Daily oral low-dose vitamin A supplementation is helpful to improve the maternal vitamin A status and can also play a positive role in vitamin A status of infants through breast milk.

Vitamin A Status

Postpartum vitamin A supplementation of mothers and infants is recommended, but the efficacy has been questioned. In this double-blind, placebo-controlled trial, Kenyan mother–infant pairs were randomised to maternal vitamin A (400 000 IU) or placebo < 24 h postpartum, and infant vitamin A (100 000 IU) or placebo at 14 weeks. Milk retinol was determined at weeks 4, 14 and 26, and maternal and infant serum retinol at weeks 14 and 26. Infant retinol stores were assessed at week 26, using a modified relative dose response (MRDR) test. Among 564 women, serum retinol at 36 weeks gestation was 0·81 (sd 0·21) μmol/l, and 33·3 % were < 0·7 μmol/l. Maternal serum retinol was not different between groups, but milk retinol was higher in the vitamin A group: (0·67 v. 0·60 μmol/l; 0·52 v. 0·44 μmol/l; 0·50 v. 0·44 μmol/l at 4, 14 and 26 weeks, respectively). When expressed per gram fat, milk retinol was higher in the vitamin A group only at 4 weeks. Infant serum retinol was not different between groups. However, although most infants had deficient vitamin A stores (MRDR>0·06 %) at 26 weeks, vitamin A to infants, but not mothers, resulted in a lower proportion of infants with deficient vitamin A stores (69 v. 78 %). High-dose postpartum vitamin A supplementation failed to increase serum retinol and infant stores, despite modest effects on milk retinol. Infant supplementation, however, increased stores. There is a need for a better understanding of factors affecting absorption and metabolism of vitamin A.

Background: Beside calorie and protein consumption micronutrients like folic acid, vitamin D and vitamin A have been postulated to play major role in intrauterine growth of neonates. Vitamin A compounds are critical for vision, reproduction, embryonic development, immune function and regulation of cell proliferation and differentiation.Aims and Objectives: To determine the relationship of maternal serum vitamin A levels with birth weight of babies.Material and Methods: Study group consisted of 58 randomly selected mothers who delivered at term small for gestational age babies (birth weight less than 2.5kg.). The control group comprises of 52 matched mothers, who delivered normal babies. Biochemical estimation of serum vitamin A was done by HPLC method using sigma reagent of all subjects.Results: Significantly high (p<0.05) number of mothers in study group had low serum vitamin A level compared to mothers in control group. There was a linear relationship between vitamin A status and mean birth weight of the babies.Conclusion: Although the low serum vitamin A level of mothers was significantly associated with intrauterine growth retardation, the exact effect of a vitamin A deficiency on the birth weight of babies remain unclear, but the finding suggests the importance of adequate vitamin A supplementation to pregnant mothers in India.Asian Journal of Medical Sciences Vol.8(3) 2017 30-34

Vitamin A and E are important during pregnancy, the neonatal period, and childhood. The objective of this study was to assess whether maternal RRR-a-tocopherol supplementation affects serum and breast milk retinol. Serum was collected at baseline and twenty days later, and breast milk, at baseline, and on days 1, 7, and 20 after delivery. After the baseline serum collection, the supplemented group (n=16) received a single 400 IU of RRR-&alpha;-tocopherol. The control group (n=18) was only performed collections. Retinol and alpha tocopherol levels were determined by liquid chromatography. Serum retinol and alpha tocopherol at baseline and 20 days after delivery indicated proper vitamin A (&gt; 20 &micro;g/dL) and E (&gt; 516 &mu;g/dL) statuses in the control and supplemented groups (p &gt; 0.05). Colostrum retinol levels on days 1 and 7 after delivery were significantly higher in the supplemented group (p = 0.018 and p = 0.012, respectively). Maternal vitamin E supplementation increased colostrum retinol by 52.23% and 111.2%, 24 hours and 7 days, respectively. However, retinol in mature milk did not differ between the groups (p &gt; 0.05). In conclusion, the supplementation with 400 IU of RRR-&alpha;-tocopherol improved vitamin A bioavailability in breast milk.

Abstract To evaluate the effect of vitamin A supplementation in postpartum infants and women on serum retinol levels and breast milk. The databases Medline, PubMed, Lilacs and SciELO were consulted. The descriptors used were vitamin A, dietary supplement, child, postpartum period, infant and nutrition programs policies. Search found 7432 articles. After elimination of duplicity and application of eligibility criteria, 8 studies remained. All evaluated the effect of vitamin A supplementation on immediate postpartum, five studies used retinyl palmitate supplementation, one with retinyl palmitate and two did not specify the form of supplementation. Six studies evaluated colostrum and two included supplementation of children. It was found that supplementation in the puerperium increases the concentrations of serum retinol and breast milk, however, this result was in the short term and was relevant when the previous concentrations of the mother were low. When maternal serum concentrations are adequate, the retinol content in milk does not change, with little relevance for children. Further studies should be performed to evaluate the effect of megadoses supplementation on serum concentrations of children.

We tested the effects of vitamin A supplementation on the antibody titre of 40 healthy volunteers [age range: 10-35 years], who had received a complete course of antirabies vaccine [5 injections over 30 days]. After determining the baseline serum vitamin A status of 80 volunteers, 20 pairs were matched for serum vitamin A level, body mass index, age, sex and socioeconomic status. One person from each pair was randomly assigned to an experimental or control group. The experimental group received vitamin A and antirabies vaccine. Controls received only the vaccine. The experimental group had significantly greater [2.1 times] serum antirabies titre than controls. This finding is an important step towards improving the economy of dosage of antirabies vaccines.
