Insights
A new vitamin A supplementation (VAS) regimen, starting with intramuscular (IM) injections and followed by oral doses, effectively prevents vitamin A deficiency in very low birth weight (VLBW) neonates. This practical approach significantly improves plasma retinol levels in these vulnerable infants.
Area of Science:
- Neonatal Medicine
- Nutritional Science
- Pediatric Health
Background:
- Vitamin A deficiency is prevalent in very low birth weight (VLBW) neonates.
- Intramuscular (IM) vitamin A injections can reduce bronchopulmonary dysplasia but are impractical.
- Oral vitamin A supplementation has shown limited efficacy in achieving adequate plasma levels.
Purpose of the Study:
- To evaluate a combined intramuscular (IM) followed by oral vitamin A supplementation schedule.
- To determine if this regimen can effectively reduce vitamin A deficiency in VLBW infants.
- To assess plasma retinol levels in VLBW neonates receiving the combined supplementation.
Main Methods:
- A blinded, randomized controlled trial was conducted in a level III neonatal unit.
- VLBW neonates (750-1250g) received either vitamin A supplementation (VAS) or placebo.
- VAS group received IM vitamin A followed by oral doses for 28 days; primary outcome was vitamin A deficiency on day 28.
Main Results:
- Over 90% of enrolled VLBW neonates were vitamin A deficient at baseline.
- The incidence of vitamin A deficiency on day 28 was significantly lower in the VAS group (4%) compared to placebo (61%) (p < 0.001).
- Median plasma retinol levels were significantly higher in the VAS group compared to placebo (489 vs. 184 μg/L, p < 0.001).
Conclusions:
- A combined IM and oral vitamin A supplementation strategy is highly effective.
- This regimen significantly reduces vitamin A deficiency in VLBW infants.
- The practical approach improves plasma retinol levels, addressing a critical nutritional need in VLBW neonates.
Abstract:
Multiple intramuscular (IM) injections of vitamin A have been shown to decrease bronchopulmonary dysplasia in very low birth weight (VLBW) neonates. However, this regime is neither practical nor popular. Oral vitamin A has failed to achieve adequate plasma levels. We aimed to investigate if a schedule of initial IM followed by oral supplementation can reduce vitamin A deficiency. This was a blinded, randomized controlled trial, conducted in a level III neonatal unit. Neonates with birth weight from 750 to 1250 g, were enrolled at the age of 24-96 h of life. They were randomly allocated to vitamin A supplementation (VAS) (n = 61) or placebo group (n = 59). VAS group received vitamin A 5000 IU IM on alternate days till establishment of adequate enteral feeds, followed by oral 10,000 IU daily for 28 days. The primary outcome was incidence of vitamin A deficiency (plasma retinol < 200 μg/L) on day 28. A total of 120 neonates with mean (SD) gestation age and birth weight of 31 (2.4) weeks and 1065 (141) g, respectively were enrolled. More than 90% of cases were vitamin A deficient at the baseline. The proportion of vitamin A deficient infants on day 28 of study was significantly lower in VAS group compared to placebo group (4% vs. 61%, p < 0.001). The median (1st-3rd quartile) plasma retinol levels (μg/L) were significantly higher in VAS group compared to placebo [489 (295,627) vs. 184 (156,240), p < 0.001]. We conclude that the IM followed by oral VAS significantly reduced the incidence of vitamin A deficiency in VLBW infants.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
