- Overview Tuberculosis and Vitamin D
- Tuberculosis 4.5X more likely if vitamin D less than 10 nanogram – meta-analysis May 2015
- TB conversion 10X less likely if have sufficient vitamin D – Dec 2011
Items in both categories TB and Intervention are listed here:
- Spinal TB surgery now includes Vitamin D as the standard of care (5,000 IU daily) – Sept 2024
- TB treatment helped by the addition of Vitamin D (100,000 IU bi-weekly) – RCT April 2024
- Tuberculosis not prevented by a tiny amount of vitamin D (equiv to 1,400 IU daily) – RCT May 2023
- Tuberculosis treatment helped a bit by a bit of Vitamin D - RCT Feb 2022
- TB not prevented by a small amount of Vitamin D (2,000 IU daily average, Mongolia) – RCT July 2020
- TB not treated by vitamin D given for only 2 months – RCT Sept 2017
- Tuberculosis recovery speeded up by single 450,000 IU dose of vitamin D – RCT Jan 2017
- Tuberculosis treatment greatly helped by injection of 200,000 IU of vitamin D – RCT April 2016
- Tuberculosis -100 percent cure rate with 10,000 IU of vitamin D daily – RCT 2006
- Tuberculosis not treated by lots of vitamin D for 16 weeks – RCT Sept 2015
- Every TB patient benefited from 2 doses of 600,000 IU of vitamin D – RCT Jan 2013
- TB treatment helped with Vitamin D – RCT Sept 2012
- Probability of getting TB reduced 60 percent with just 800 IU of vitamin D – RCT Aug 2012

Rationale: Existing trials of adjunctive vitamin D in the treatment of pulmonary tuberculosis (PTB) are variously limited by small sample sizes, inadequate dosing regimens, and high baseline vitamin D status among participants. Comprehensive analyses of the effects of genetic variation in the vitamin D pathway on response to vitamin D supplementation are lacking.
Objectives: To determine the effect of high-dose vitamin D3 on response to antimicrobial therapy for PTB and to evaluate the influence of single-nucleotide polymorphisms (SNPs) in vitamin D pathway genes on response to adjunctive vitamin D3.
Methods: We conducted a clinical trial in 390 adults with PTB in Ulaanbaatar, Mongolia, who were randomized to receive four biweekly doses of 3.5 mg (140,000 IU) vitamin D3 (n = 190) or placebo (n = 200) during intensive-phase antituberculosis treatment.
Measurements and Main Results: The intervention elevated 8-week serum 25-hydroxyvitamin D concentrations (154.5 nmol/L vs. 15.2 nmol/L in active vs. placebo arms, respectively; 95% confidence interval for difference, 125.9–154.7 nmol/L; P < 0.001) but did not influence time to sputum culture conversion overall (adjusted hazard ratio, 1.09; 95% confidence interval, 0.86–1.36; P = 0.48). Adjunctive vitamin D3 accelerated sputum culture conversion in patients with one or more minor alleles for SNPs in genes encoding the vitamin D receptor (rs4334089, rs11568820) and 25-hydroxyvitamin D 1α-hydroxylase (CYP27B1: rs4646536) (adjusted hazard ratio ≥ 1.47; P for interaction ≤ 0.02).
Conclusions: Vitamin D3 did not influence time to sputum culture conversion in the study population overall. Effects of the intervention were modified by SNPs in VDR and CYP27B1.
