The Effect of Zinc, β-carotene, and Vitamin D3 in Preterm Delivery Through Placental MyD88, TRIF, NFkB, and IL-1β

Registration Number
NCT03005496
Lead Sponsor
Indonesia University
Brief Summary

This study is a controlled trial which compares the effect of zinc, beta-carotene, and Vitamin D3 supplementation in pregnant women which has preterm birth. The measured outcome is zinc, vitamin A, and 25(OH)D level in serum and placenta, MyD88, TRIF, NFκB, and IL-1β levels in placenta.

Detailed Description

The research will be held in Cipto Mangunkusumo General and Budi Kemuliaan Hospital.

Each participant of each group will be given the medication of preterm birth hospital protocol, which includes nifedipine 4x10 mg as tocolytic agent, dexamethasone 2x6 mg intravenous for 2 days which aims to support lung maturation, and antibiotic. Then, the blood sample is obtained for zinc, vitamin A and 25(OH)D levels examination. Subjects will be divided into 2 groups which are group whose given the oral zinc 50 mg/day, oral beta-carotene 25,000 IU and oral vitamin D3 50,000 IU/week supplementation, and group who is not given the intervention. Each participant will be observed until delivery. After delivery, level of zinc, vitamin A, and 25(OH)D in serum and placenta will be measured, as well as level of MyD88, TRIF, NFκB, and IL-1β in placenta.
