In vitro work suggests that 1-alpha-25-(OH) 2 D modulates host cell responsiveness to the T cell cytokine, interferon gamma (IFNγ). IFNγ is one of the key mediators of protective immunity against Mycobacterium tuberculosis infection therefore; vitamin D may enhance the host immune responses against the pathogen. The objectives of this study were to determine whether supplementation of vitamin D in patients with Tuberculosis could impact recovery.Methods:266 patients were randomized to receive either 600,000 IU of Intramuscular vitamin D3 or placebo for 2 doses. Clinical assessments were done at 4, 8 and 12 weeks from baseline. Blood samples were obtained at 0 and 12 weeks. Statistical comparisons between outcome variables at 0 and 12 weeks were performed.Main Results: 259 patients completed the study. At the end of 12 weeks, the vitamin D arm demonstrated significantly greater mean weight gain; + 4.02 (95\%CI 3.18,4.86) v/s + 2.61 (95\% CI +1.99,2.23), p 0.007 and increases in BMI; + 1.48 (95\% CI 1.17, 1.78) v/s + 0.96 (95\% CI 0.72,1.20), p 0.008 as compared with the placebo arm. There was a significant difference in chest radiographic improvement in the vitamin D group; number of zones involved -2.21 (95\% CI -1.91, -2.51) v/s -1.77 (95\% CI -1.51, -2.03), p 0.031 and resolution of cavitation 73(65.7\%) v/s 60 (55\%), p 0.05.No differences were seen in TB score or sputum smear conversion. At follow up there was a significant increase in mean Vitamin D levels of the treatment arm; 62.88 v/s -7.30 for the placebo arm, p \< 0.0001.Conclusions:Vitamin D supplementation significantly impacted clinical improvement in patients with pulmonary TB.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/40/Suppl_56/P2574}, eprint = {https://erj.ersjournals.com/content/40/Suppl_56/P2574.full.pdf}, journal = {European Respiratory Journal} }
