A randomized, placebo-controlled, clinical trial of vitamin D supplementation in patients with pulmonary tuberculosis’. Secondary outcomes were differences in whole blood cell antigen-stimulated Interferon-gamma(IFN-g) responses, differences in sputum conversion rates and improvements in the TB score. I want to hear from people who have overcome this deficiency and how they did it. Changes in serum 25 hydroxyvitamin D levels in the two groups is shown in Additional file 1: Figure S1. FA contributed to study design, data collection, analysis and interpretation of data. We previously discovered that high concentrations of vitamin C sterilize cultures of drug-susceptible and drug-resistant Mycobacterium tuberculosis Here, we tested … Data depicts IFN-g ♦secretion in unstimulated and antigen stimulated whole blood cells. Ascorbic acid is an ingredient of a number of vitamin preparations and some cough and cold remedies that are available to buy from retail outlets. PubMed Central  10.1111/j.1440-1797.2011.01555.x. All Rights Reserved. However, no difference was observed in MTBs-induced IFN-g levels compared between 0 and 12 weeks in the placebo group. Combination of anti-tuberculosis drugs with vitamin C or NAC against different Staphylococcus aureus and Mycobacterium tuberculosis strains. BMC Infect Dis 13, 22 (2013). IFN-g responses pre- and post-treatment between baseline 25-(OH)hydroxy vitamin D levels and TB severity groups were compared using the Kruskal-Wallis non-parametric test. 2008, 93 (3): 677-681. Is it safe to delay your period for your holiday? You can take the tablets at whatever time of day you find easiest to remember, either before or after meals. This data suggests a role for 25-hydroxyvitamin D supplementation in boosting host immunity particularly in those with deficient 25 hydroxyvitamin D levels. Its components include self-reported symptoms (cough, shortness of breath, night sweats, chest pain, haemoptysis), clinical signs (tachycardia, pallor, fever, auscultatory findings) body mass index (BMI) and mid-upper arm circumference (MUAC). Only two patients in the vitamin D arm died during the study; one death was due to respiratory failure occurring within the initial 2 weeks of antituberculous therapy. 2003, 10 (4): 602-611. Early secreted and T cell activated 6 kDa (ESAT6) and Mycobacterium tuberculosis sonicate (MTBs) antigen induced whole blood stimulated IFN-g responses were measured at 0 and 12 weeks. MTBs- stimulated IFN-g levels are increased post-therapy in TB patients with deficient Vitamin D levels. See if you are eligible for a free NHS flu jab today.

PubMed  Ascorbic acid is known to function as an antioxidant by savaging ROS, and a number of studies have suggested that vitamin C supplementation can impact the immune system.

Salahuddin, N., Ali, F., Hasan, Z. et al. In a meta-analysis, vitamin D supplementation decreased the incidence of acute respiratory infection.8 In subgroup analyses, the protective effect of vitamin D was greater in patients with baseline serum 25-hydroxyvitamin D concentrations < 25 nmol/L (vs ≥ 25 nmol/L) and isolated to those receiving daily dosing (vs bolus dosing).8 In light of these data, a recent article recommended that patients at risk for COVID-19 consider starting daily vitamin D supplementation to raise serum 25-hydroxyvitamin D concentrations in order to reduce the risk for infection.7 While this strategy is unlikely to cause harm, it has not been specifically evaluated for prevention of COVID-19 infection and should be further studied before it is recommended to patients. There was a trend towards greater association of haemoptysis with lower levels of vitamin D (p 0.049). Print 2018 Nov. Khameneh B, Fazly Bazzaz BS, Amani A, Rostami J, Vahdati-Mashhadian N. Microb Pathog. 106 (89.8%) patients in the vitamin D arm had 50% or more reduction in cavity size v/s 111 (94.8%) in the placebo arm (p 0.035). 2007, 179 (4): 2060-2063.

Your dose will be on the label of the pack to remind you about what the doctor said to you. Ascorbic acid, zinc, vitamin D, and N-acetylcysteine have biologic plausibility for the prevention and treatment of COVID-19 and are candidates for clinical trials evaluating patients with these indications.
