Administration of vitamin in the infected found to have reduced mortality Do high Vitamin D levels reduce the risk of coronavirus infection, and administration of the vitamin in the infected patients considerably reduce mortality? Yes, says a study done by the doctors of Nizams Institute of Medical Sciences (NIMS) on the COVID-affected patients of Gandhi Hospital, Secunderabad. The report published in ‘www.nature.com’ says that Vitamin D is a potential immuno-modulator and its adjunctive role in the treatment of COVID-19 is established through the study. Maheshwar Lakkireddy, a orthopaedician at NIMS and one of the authors of the study says that improvement of Serum Vitamin D level to 80 to 100 Nanograms per MilliLitre (ng/ml) has significantly reduced the inflammatory markers of COVID 19 (N/L ratio, CRP, LDH, IL6, Ferritin) without any side effects. The authors who defined this administration of Vitamin D study as ‘Pulse D Therapy’ reveal that the study was done on 130 patients. The patients were randomised into Vitamin D (VD) and Non-Vitamin D (NVD) groups. The VD group received Pulse 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 NVD group received standard treatment alone.
