case series: Vitamin D deficiency in exclusively breastfed term and late preterm neonates

摘要

Vitamin D plays an integral role in calcium metabolism. Vitamin D levels in neonates are determined by in-utero transfer of vitamin D and through breast milk. This in turn depends on the maternal stores of vitamin D. We present case series of term and late preterm neonates who were admitted to tertiary level neonatal ICU with vitamin D deficiency manifesting as symptomatic hypocalcemia.
