NPH Insulin Versus Insulin Glargine Versus NPH Insulin Plus Insulin Glargine for the Treatment of Dexamethasone-Induced Hyperglycemia in Patients With COVID-19: A Retrospective Cohort Study.

Background: Dexamethasone use in patients hospitalized with COVID-19 significantly reduces mortality; however, it commonly results in hyperglycemia. Optimal treatment of dexamethasone-induced hyperglycemia is not well established.

Objective: The study purpose was to assess the difference in blood glucose (BG) control between insulin glargine, neutral protamine hagedorn (NPH) insulin, and insulin glargine plus NPH insulin for dexamethasone-induced hyperglycemia in patients with type 2 diabetes (T2DM) and COVID-19 infection.
