Low vitamin D levels were consistently reported as a risk factor for worse outcomes in hospitalized COVID-19 patients. Emerging evidences suggest that in 50–70% of COVID-19 survivors several post-COVID symptoms can be observed up to 3 months after acute-disease, representing a novel clinical condition defined Long-COVID syndrome. To date, the predisposing factors for this syndrome are still poorly understood. We retrospectively aimed at evaluating the influence of 25(OH) ...

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...
