Lower maternal vitamin-D levels' association with early-onset neonatal sepsis in term neonates

To determine the association of low maternal serum vitamin-D levels with serum vitamin-D levels of their term neonates and higher risk of early onset neonatal sepsis (EOS). Study Design: Prospective observational study. Place and Duration of Study: Neonatal intensive care unit (NICU) of Department of Pediatrics; Combined Military Hospital (CMH) Malir Cantt Karachi, from Apr 2016 to Apr 2017. Material and Methods: Ninety three term neonates with EOS formed the "sepsis group" and equal number (93) of healthy term neonates without sepsis were included in the control group selected as per inclusion criteria. Blood samples of mothers and their neonates were drawn during the first 72 hours after delivery for measure-ment of serum vitamin-D levels. Results: Mean serum vitamin-D levels were 18.16 ± 8.21 ng/ml and 13.93 ± 13.29 ng/ml in the mothers and their neonates respectively in the sepsis group and were significantly lower (p-value <0.001) than the mean serum vitamin-D levels of 33.35 ± 12.70 ng/ml and 27.92 ± 7.58ng/ml in the mothers and their neonates respectively in the control group. Vitamin-D deficiency was found in significantly higher number of cases in mothers (88.17%) and neonates (82.80%) in sepsis group as compared to 52.69% mothers and 39.78% neonates in control group (p-value<0.001). There were 14 (15.05%) cases of culture proven sepsis in the study group as compared to just 01 (1.08%) case of culture proven sepsis in control group which was statistically significant (p-value<0.001). Conclusion: Lower maternal serum vitamin-D levels are associated with lower serum vitamin-D levels and higher risk of EOS in their term neonates. (author)
