Hypocalcemia has been recently identified as a major biochemical distinctive feature of COVID-19, predicting poor clinical outcomes. Besides the calcium-dependent viral mechanisms of action and the enhanced cellular permeability to calcium ions, we previously hypothesized that hypovitaminosis-D could be a predisposing factor to hypocalcemia. Actually, high prevalence of vitamin D (VD) deficiency in COVID-19 patients (pts) was reported by several studies, but, to date, only few...
