Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluate the effect of two different doses of vitamin D on T-regulatory cells in preterm infants. Half of the subjects receives 400 IU vitamin D and the other half receives 800 IU vitamin D.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Vitamin D, in addition to its bone mineralization effect, is an immune- modulatory agent. Fetal and premature cellular immunity are generally delayed. Whether vitamin D can enhance cellular immunity by increasing T regulatory cells is unknown. The effect of two different doses of vitamin D; 400 IU and 800 IU will be studied.
