Vitamin D supplementation in tuberculosis patients: A cross-sectional study
Previous studies have not been able to show with certainty the effect of vitamin D supplementation in tuberculosis patients. The objective of this study is to determine whether vitamin D supplementation to patients with tuberculosis could influence 25-hydroxy- vitamin D (25(OH)D) and calcium serum levels. Results: after 28 days, the vitamin D supplementation showed significant increase of 25(OH)D serum level at the end point (p = 0.001), but not for the calcium serum level (p = 0.3). Conclusions: supplementation with 1,000 IU vitamin D per day increased the 25(OH)D serum level but there was no association with the calcium serum level. These results suggest a.
