Objective: Increased levels of inflammatory factors in newborns are often associated with lower maternal vitamin D levels. This study aimed to find out the relationship between maternal and umbilical cord vitamin D serum levels on umbilical cord Interleukin-6 (IL-6) and serum C-Reactive Protein (CRP) levels in premature infants. Methods: The study was an observational analytic, cross-sectional design in mothers who underwent preterm birth at 28-34 weeks' gestation due to premature rupture of membranes (PROM) and their infants at Dr. Cipto Mangunkusumo General Hospital (RSCM), Jakarta and Persahabatan General Hospital, Jakarta, from January 2017 to August 2018. Levels of serum vitamin D of the maternal and umbilical cord, umbilical cord IL-6 and serum CRP in premature infants were recorded. Vitamin D level was divided into deficiency (<10 ng/mL), insufficiency (10-29 ng/mL), and normal (≥30 ng/mL) groups. The relationship of vitamin D levels with IL-6 and CRP was carried out using Kruskal Wallis test. Results: A total of 70 subjects met the research criteria. Umbilical cord IL-6 and serum CRP levels in premature infants of vitamin D deficient mothers were higher (20.31 pg/mL and 0.50 mg/L) compared to insufficient (3.34 pg/mL and 0.45 mg/L) and normal mothers (3.29 pg/mL and 0.30 mg/L), although not statistically significant (IL-6 p = 0.665, CRP p = 0.89). Referring to the umbilical cord blood vitamin D levels, the results were different and not as expected, in which the umbilical cord IL-6 and serum CRP levels of preterm infants in the deficiency (3.76 pg/mL and 0.35 mg/L) and insufficiency (3.37 pg/mL and 0.40 mg/L) groups were lower (IL-6) and not different (CRP) than the normal group (9.41 pg/mL and 0.40 mg/L). Conclusions: There were atendency for an increase in umbbilical cord IL-6 and serum CRP level in premature infants of Vitamin D deficient mother although these were not statistically significant. Based on the levels of vitamin D umbilical cord blood, the CRP levels in the serum of premature infants were not different, while the IL-6 levels in the deficiency and insufficiency group were lower than in the normal group.
