  1. 1. By- Dr. Amlendra Yadav Phase – A Resident Neonatology
  2. 2. Vitamin-D levels in exclusively breast fed infants less than six months of age:Do they need supplementation?
  3. 3. Tushar Jagzape , Saherish Khan Source Sri Lanka Journal of Child Health, 2014; 43(2): 92-96
  4. 4.  Well baby clinic of tertiary care rural Teaching Hospital of Central India. Study Design Observational, cross-sectional study.
  5. 5.  Measurement of serum 25(OH) D levels in exclusively breastfed babies.
  6. 6. Vitamin D, the generic term for a family of secosteroids with anti-rachitic activity, comprises a family of fat soluble vitamins and hormones that, when deficient in the diet, causes rickets from defective mineralization of growing bone and osteomalacia in non- growing bones. Vitamin D2 (ergocalciferol), obtained from the influence of ultraviolet B radiations on plants and yeast and vitamin D3 (cholecalciferol), produced in skin by ultraviolet ray are the two main form of vitamin D.
  7. 7.  Both forms are metabolized similarly in the body, first by hepatic 25 hydroxylation into inactive but stable 25(OH) D (Calcidiol) and then by renal 1- hydroxylation into active but unstable 1, 25(OH)2 D (Calcitriol). Calcitriol exerts its effects by binding to vitamin D receptor, which belongs to the family of nuclear hormone receptors.
  8. 8.  It was an observational, cross sectional study. Thirty healthy infants less than 6 months of age, on exclusive breast feeding and not on any vitamin supplementation were randomly selected. Vitamin D, serum calcium, phosphorus and alkaline phosphatase levels were measured in all these babies and those with clinical features of rickets were subjected for x-ray evaluation.
  9. 9. Exclusion Criteria  Age less than 28 days (neonates), critically sick infants, formula fed babies and babies receiving vitamin-D supplements.
  10. 10. Results
  11. 11. Vitamin D deficiency is highly prevalent in exclusively breastfed healthy infants and hence vitamin D should be supplemented.
  12. 12.  The sample size was small.  Because of financial constraints and non-availability of test, parathyroid hormone levels were not done.  We could not correlate the gestational age and vitamin D status as we could not recruit preterm babies who were all on vitamin supplementation.
  13. 13. Jain V, et al Vitamin D deficiency in healthy breastfed term infants at 3 months and their mothers in India: Seasonal variation and determinants. Indian Journal of Medical Research 2011; 133(3): 267-73, the prevalence rate was 86.5%.
  14. 14. THANK YOU
