Cited by some experts among the potential treatments during the pandemic, is vitamin D really effective against severe forms of Covid -19? Yes, today I believe the Angers University Hospital, which has just communicated the results of the Covit-Trial study, which it piloted. “With a very high level of evidence”, the conclusions indeed demonstrated “the interest of a high dose of vitamin D, administered within 72 hours of the diagnosis of Covid-19, to frail elderly people who have contracted infection,” the hospital said in a statement.
Between April and December 2020, 260 patients over the age of 65 from the nine university hospitals and their nursing homes took part in this study. Within three days of diagnosis, some received a standard dose of vitamin D while others received a much higher dose. In the end, “a significant reduction in the death rate” was observed.
“This result is important and consistent with what we knew about the anti-inflammatory effects of vitamin D, applying very significantly the risk of death at 14 days, and avoiding the inflammatory runaway and cytokine storm observed in severe forms of Covid-19″, observes Cédric Annweiler, head of the geriatrics department at the CHU d’Angers.
The authors of the study therefore recommend achieving “as quickly as possible a satisfactory vitamin D status in the elderly with Covid-19, using high-dose supplementation as soon as the diagnosis is made”.
