Cord Blood 25(oh)-Vitamin D Level in Preterm Infants and Associated Morbidities

Is Higher Cord Blood 25(Oh)-Vitamin D Level Preventive For Any Morbidity Including Rds, Pda, Nec, Bpd And Rop In Preterm Infants

Experimental and observational studies have shown that vitamin D deficiency may be associated with an increased risk for non-bone diseases and/or abnormal development for the other systems of fetus. The aim of this study is to determine the relationship between cord blood 25-hydroxyvitamin D (25 (OH) D) concentrations and the subsequent risk of morbidities including RDS, PDA, NEC, BPD AND ROP in preterm infants.

It was shown that vitamin D play important role in the pathogenesis of long term morbidities of newborn. Experimental and observational studies have shown that vitamin D deficiency may be associated with an increased risk for non-bone diseases and/or abnormal development for the other systems of fetus. The aim of this study is to determine the relationship between cord blood 25-hydroxyvitamin D (25 (OH) D) concentrations and the subsequent risk of morbidities including RDS, PDA, NEC, BPD AND ROP in preterm infants.
