Abstract

Background The high morbidity and mortality of premature neonates remain significant problem in Indonesia with respiratory distress syndrome (RDS) as one of the most common problem. Vitamin D plays  an important role in lung maturity. Vitamin D deficiency causes epithelial cell inflammation, leading to a higher risk of RDS. Previous studies suggest that T regulatory cells (Treg) in inflammatory diseases, such as RDS in neonates, are possibly linked to vitamin D deficiency.


Objective To determine the role of vitamin D on RDS and Treg cells in very premature or very low birth weight neonates.


Methods A prospective cohort study conducted on premature neonates in Neonatology Division, Department of Child Health, Dr. Cipto Mangunkusumo Hospital, Jakarta, Indonesia. Umbilical cord blood samples were collected to evaluate total vitamin D 25-OH levels and Treg cells. Subjects with RDS were evaluated until the end of the observation period.


Results The mean umbilical cord vitamin D level was 15.79 (SD 6.9) ng/mL, and 53% of the subjects were found to be deficient. As much as 65.1% of neonates had RDS. The mean Treg level was 11.38 (SD 2.45)%. No significant correlation was observed between vitamin D level and the occurrence of RDS (RR 0.87; 95%CI 0.56 to 1.34; P=0.53); vitamin D level and the dysregulation of Treg cells (RR 1.30; 95%CI 0.76 to 2.21; P=0.31) as well as between Treg dysregulation and RDS (RR 1.11; 95%CI 0.70 to 1.75; P=0.64). However, we found that RDS group had a lower gestational age and higher presentation of dysregulation Treg.


Conclusion In very premature or very low birth weight neonates, no association between occurence of RDS and vitamin D deficiency as well as Treg cell dysregulation.
