Impact of Vitamin D Supplementation on Fetomaternal Outcomes in LTBI Pregnant Females

The goal of this randomized controlled trial is to see the effect of vitamin D supplementation on fetomaternal outcomes in pregnant females with Latent Tuberculosis infection

The main question\[s\] it aims to answer are:

If Vitamin D supplementation has any impact on maternal outcomes. If Vitamin D supplementation has any impact on fetal outcomes.

This study aims to see the impact of vitamin D supplementation on fetomaternal outcomes in pregnant females with latent tuberculosis infection. A three-arm (parallel) randomized controlled trial (RCT) will be conducted in a high-burden setting. A calculated sample of 99 (33 in each group) pregnant females with LTBI will be enrolled based on predefined inclusion criteria. Vitamin D supplementation will be given as per study protocols. Group-A (No intervention), Group-B (2000IU/day), Group-C (4000IU/day). To maintain the safety measures throughout the study all the study participants will be monitored for hypervitaminosis D. Informed consent will be obtained from all participants. The study will be conducted after approval by the ethical review board(s). The final analysis will be based on the effect of vitamin D supplementation on pre-defined fetomaternal outcomes.
