Do we know that there is 13 scientific evidence already that confer a direct association between #VitaminD deficiency & #COVID19 disease severity-mortality? Yet, no standard guidelines available at the national or international level for common people. THREAD must read and share.

1. Latest trial from Spain with 76 COVID 19 patients found that calcifediol (active form of Vit-D) reduced ICU admission & mortality in 50 patients treated w/calcifediol. only 1 among these 50 needed ICU admission in comparison to 13/26 w/out intervention. #tbl0005">https://www.sciencedirect.com/science/article/pii/S0960076020302764?via%3Dihub #tbl0005">https://www.sciencedirect.com/science/a...

2. A cohort study reported that only 17.6% of patients required oxygen who received Vit-D, magnesium & B12 combination in comparison with 61.5% who didn& #39;t receive this combination.

3. A study from Iran found significant alterations in vitamin D and ACE levels as well as NLR (neutrophil to lymphocyte ratio) in the patients’ group. The contribution of those factors with the prognosis and severity of the disease has been shown.

4. In 70 patients, researchers observed more Vitamin D deficiency among COVID positive patients and concluded worse morbidity outcomes may be seen in older adults with vitamin D deficiency and COVID-19. https://pmj.bmj.com/content/early/2020/08/26/postgradmedj-2020-138712?rss=1">https://pmj.bmj.com/content/e...

5. A retrospective, observational study with 42 patients revealed that after 10 days of hospitalization, severe vitamin D deficiency patients had a 50% mortality probability, while those with vitamin D ≥10 had a 5% mortality risk.
