SHR # 2574 :: Low Plasma Vitamin D Levels Increased Risk of Catching COVID-19 plus New Approach to Treating Osteoarthritis - Dr. Milana Frenkel-Morgenstern, PhD - Dr. Bruce Cronstein, MD - Vitamin D is recognized as an important co-factor in several physiological processes linked with bone and calcium metabolism, and also in diverse non-skeletal outcomes, including autoimmune diseases, cardiovascular diseases, type 2 diabetes, obesity and cognitive decline, and infections. In particular, the pronounced impact of vitamin D metabolites on the immune system response, and on the development of COVID-19 infection by the novel SARS CoV-2 virus, has been previously described in a few studies worldwide. The collaborative group of scientists from the Leumit Health Services (LHS) and the Azrieli Faculty of Medicine of Bar-Ilan University aimed to determine associations of low plasma 25(OH)D with the risk of COVID-19 infection and hospitalization. Using the real-world data and Israeli cohort of 782 COVID-19 positive patients and 7,025 COVID-19 negative patients, the groups identified that low plasma vitamin D level appears to be an independent risk factor for COVID-19 infection and hospitalization. PLUS The study results revolve around the long-established idea that machines within animal and human cells turn the sugars, fats, and proteins we eat into energy used by the body's millions of cells. The molecule most used to store that energy is called adenosine triphosphate, or ATP. Along with this central role in metabolism, adenosine also helps signal other cells and serves as a building block of genetic material, and so is central to the growth of human tissue. Previous research had shown that maintaining supplies of adenosine, known to nourish the chondrocyte cells that make cartilage, also prevented osteoarthritis in similar animal models of the disease.
