Abstract

Introduction: Newborns are more susceptible to infections as both innate and adaptive immune systems are not entirely developed. Vitamin D is a fat-soluble steroid hormone that contributes to the maintenance of normal calcium homeostasis and skeletal mineralization. Vitamin D also has immunomodulatory effects on immune function. It was suggested that it might have a role in the optimal functioning of the innate immune system by inducing antimicrobial peptides in epithelial cells, neutrophils and macrophages. Aim of the Work: The aim of this study was to determine the role of vitamin D levels as diagnostic predictor of early onset sepsis development in term neonates. Patients and Methods: Fourty term infants with clinical and laboratory findings of EOS (study group) and 40 healthy infants with no signs of clinical/laboratory infection (control group) were enrolled. Blood was drawn at the time of admission during the first 3 postnatal days of life in both groups for measurement of 25-hydroxyvitamin D (25-OHD) levels. Result: Neonatal 25-OHD levels (11.59 ± 4.66ng ml−1) in the study group were significantly lower than those of the control group (27.35 ± 3.45ng ml−1, P<0.001). Severe vitamin D deficiency was significantly more common in the sepsis group. Conclusion: Lower neonatal 25-OHD levels are associated with EOS. These data suggest that adequate vitamin D supplementation during pregnancy may be helpful to prevent EOS in term neonates.
