Hyperglycemia did show this association (>107 mg/dL), although with a lower cut-off point than what was reported by Reiterer et al. NSv had lower insulin levels compared to Sv, though without statistical significance; this is consistent with compromised insulin secretion in severe cases of COVID-19 reported by Ilias et al. The decreases in circulating insulin levels could be as a result of the direct damage of SARS-CoV-2 against pancreatic beta cells. Here, INS is linked to COVID-19.
