Vitamin D and COVID 19 – High dose supplementation therapy and Evidences

·         A well-established association that Vitamin D deficiency and COVID 19 infection susceptibility, severity and mortality stems from several observational studies (Jain, 2020) (Grant, 2020) (De Smet, 2020) (Merzon, 2020). Vitamin D has multi spectrum action against COVID 19, most importantly by reducing dysregulated production of self-damaging pro-inflammatory cytokines and promoting the expression of anti-inflammatory cytokines by immune cells (Gombart, 2020).

·         However, role of Vitamin D in various viral infections including has been explored including COVID 19, but the exact dosing still remains a question yet to be explored. We review evidences, which talk about the HIGH DOSE SUPPLEMENTATION THERAPY.

What is high dose supplementation therapy?

·         High dose vitamin D supplementation  therapy is a targeted approach to increase the serum vitamin D level by using high dose (60,000 IUs) oral supplementation of vitamin D daily for a specific period determined by the individual’s BMI, initial level of vitamin D and the formulation (Lakkireddy, 2019).

Evidences:

·         SHADE STUDY (Rastogi A, 2020) -Participants were randomized to receive daily 60 000 IU of cholecalciferol (oral Nano-liquid droplets) for 7 days with therapeutic target 25(OH) D >50 ng/ml (intervention group) or placebo (control group). Greater proportion of vitamin D-deficient individuals with SARS-CoV-2 infection turned SARS-CoV-2 RNA negative with a significant decrease in fibrinogen on high-dose cholecalciferol supplementation.

·         IMPACT OF DAILY HIGH DOSE ORAL VITAMIN D THERAPY ON THE INFLAMMATORY MARKERS IN PATIENTS WITH COVID 19 DISEASE (Lakkireddy M. G., 2021)- 87 patients of COVID 19 with hypovitaminosis D completed this study. In the treatment group, patients received High dose supplementation vitamin D therapy (targeted daily supplementation of 60,000 IUs of vitamin D for 8 or 10 days depending upon their BMI) in addition to the standard treatment. The other group received standard treatment alone. Daily cholecalciferol supplementation of 60,000 IU helps in achieving 25(OH)D>50 ng/ml in 75% of participants by day-14.Therapeutic, high-dose cholecalciferol supplementation led to SARS-CoV-2 RNA negative in additional 41.7% participants (p<0.001) and was useful for viral SARS-CoV-2 RNA clearance.

·         To conclude Vitamin D High dose supplementation therapy is being proposed to be effective and safe in COVID 19 patients and can be added as an adjuvant in current treatment protocols for COVID 19.
