Identification of risk factors of severe coronavirus disease 2019 (COVID-19) is critical for improving therapies and understanding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogenesis. We analyzed 184 patients hospitalized for COVID-19 in Livingston, New Jersey for clinical characteristics associated with severe disease. The majority of patients with COVID-19 had diabetes mellitus (DM) (62.0%), Pre-DM (23.9%) with elevated fasting blood glucose (FBG), or a body mass index >30 with normal hemoglobin A1c (HbA1C) (4.3%). SARS-CoV-2 infection was associated with new and persistent hyperglycemia in 29 patients, including several with normal HbA1C levels. Forty-four patients required intubation, which occurred significantly more often in patients with DM as compared with non-diabetics. Severe COVID-19 occurs in the presence of impaired glucose metabolism in patients, including those with DM, preDM, and obesity. COVID-19 is associated with elevated FBG and several patients presented with new onset DM or in DKA. The association of dysregulated glucose metabolism and severe COVID-19 suggests that SARS-CoV-2 pathogenesis involves a novel interplay with glucose metabolism. Exploration of pathways by which SARS-CoV-2 interacts glucose metabolism is critical for understanding disease pathogenesis and developing therapies.
