Precision Diabetes, Inc. and Patia announced results from a study showing that the GlycoMark blood test may be an effective marker of stress hyperglycemia and severity in COVID-19 patients, particularly in patients without diabetes.  This data was presented as a prestigious Late Breaking Abstract at the American Diabetes Association (ADA) 81st Scientific Sessions conference.

The study, "Association of Serum 1,5-Anhydroglucitol with Severity in COVID-19 Patients," was designed to assess the impact of glycemic control on COVID-19 severity.  The study was conducted at Hospital Universitario Cruces in Bilbao, Spain, and evaluated 563 patients with and without diabetes.

In a cross-sectional analysis of all patients, the 1,5-anhydroglucitol test (GlycoMark?) significantly differentiated mild from severe COVID-19 patients.  Major differences were shown in patients without diabetes, who showed abnormal 1,5-anhydroglucitol levels in 23.3% of severe COVID-19 cases versus 10.6% of mild COVID-19 cases.  Consistent with some recent studies, hyperglycemia as measured by HbA1c, fasting glucose, or 1,5-anhydroglucitol showed no association with COVID-19 severity in patients with diabetes.

"These findings have important clinical implications," said Dr. Mirella Zulueta, Medical Director at Patia.  "The 1,5-anhydroglucitol test might be most useful in identifying stress-induced hyperglycemia and severity in COVID-19 patients without a diabetes diagnosis.  This is critically relevant as hyperglycemia may not be apparent in non-diabetic patients and is associated with poor outcomes, including mortality, in COVID-19 patients.  These patients may benefit from more intensive care and treatment."

Clinical studies comparing the mortality predictive value of 1,5-anhydroglucitol, HbA1c, and fasting glucose in COVID-19 patients were recently completed in the U.S. and Europe with results to be reported in Q3 2021.
