New Late-Breaking Data at The American Diabetes Association Show GlycoMark® May Be an Effective Test for COVID-19 Severity

RALEIGH,N.C. and SAN SEBASTIAN,Spain,June 28,2021 --Precision Diabetes,Inc. and Patia announced today 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,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.
