For hospitalized patients with COVID-19 and type 2 diabetes, four key factors have been described: (1) susceptibility to hyperglycemia due to glucocorticoid treatment; (2) less frequent blood sugar monitoring due to reduced contact with healthcare workers to minimize infection risk; (3) patient isolation, which can hinder proper diabetes management; and (4) inappropriate discontinuation of an angiotensin receptor blocker or angiotensin-converting enzyme inhibitors, medications often used to manage diabetes and blood pressure [36]. The gene discussed is ACE; the disease is diabetes mellitus.
