Hyperglycemia Predicts COVID-19 Death Even Without Diabetes

Nearly half of hospitalized COVID-19 patients without a prior diabetes diagnosis have hyperglycemia, and the latter is an independent predictor of mortality at 28 days, new research indicates.  

The findings, from a retrospective analysis of 605 patients with COVID-19 seen at two hospitals in Wuhan, China, were published online July 10 in Diabetologia by Sufei Wang, of the Department of Respiratory and Critical Care Medicine, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, and colleagues. 

Several previous studies have demonstrated a link between hyperglycemia and worse outcomes in COVID-19, and at least one diabetes diagnosis, but this is the first to focus specifically on that group of patients.

Wang and colleagues found that a fasting blood glucose of 7.0 mmol/L (126 mg/dL) or greater on admission — present in 45.6% of those without a prior diabetes diagnosis — was an independent predictor of 28-day mortality.
