Association of vitamin D with early onset sepsis in term neonates.
Pak J Med Dentistry Jan ;8(3):35-9.

Background: Vitamin D deficiency has been associated with increased viral respiratory infections and early-onset sepsis in neonates. Newborns are more susceptible to infections as both innate and adaptive immune systems are not entirely developed. Neonatal sepsis is a frequent and important cause of neonatal morbidity and mortality worldwide. The aim of the study is to determine the association of vitamin D deficiency with early onset of sepsis among term neonates. Methods: This study was conducted at Neonatal Intensive Care Unit, Ziauddin Hospital Karachi. A total of 100 neonates, with early onset sepsis (n=50) and with no sepsis (n=50as controls) were included. Blood was drawn for CBC, CRP and Vitamin D levels with levels<20ng/ml considered as vitamin D deficiency. Descriptive statistics were calculated. Chi square test was applied to see the association of vitamin D deficiency with study groups. Odd ratio >1 was considered as significant. Results: There were 64% male and 36% female among neonates with sepsis and 54% male and 46%female among controls. Mean time of onset of infection was 2.08+-0.82 days among cases. The mean serum vitamin D level was 10.56+-5.83 ng/mL and 22.18+-4.44 ng/mL among cases and controls respectively. Vitamin D deficiency was observed among 88% patients with early sepsis and among 20% non-sepsis controls and association was found significant with an odds ratio of 29.33. Conclusion: Vitamin D level in neonates with early sepsis was significantly lower than non-sepsis patients. Hence, it may be a risk factor for early onset of sepsis in term neonates.
