New Study Suggests GlycoMark® May Identify Highest Risk Patients with Prediabetes

RALEIGH,North Carolina,Sept. 22,2020 --According to new data presented at the 56th European Association for the Study of Diabetes (EASD) annual meeting,the GlycoMark blood test reflects beta-cell functional mass,which is important in identifying prediabetic individuals with the highest risk of progression to diabetes.

The study,"1,5-anhydroglucitol as a circulating biomarker of beta cell loss independently of diabetes onset," was presented by C. Jimenez-Sanchez,T. Mezza,G. Di Giuseppe,A. Giaccari,and P. Maechler of both the University of Geneva (Geneva,Switzerland) and the Universita Cattolica del Sacro Cuore (Rome,Italy). The authors conclude,"our results suggest that circulating levels of 1,5-anhydroglucitol (GlycoMark) reflect beta-cell functional mass in humans. The reduction of 1,5-anhydroglucitol levels are directly related to early metabolic defects in dysfunctional beta-cells,highlighting the importance of this biomarker in estimating beta-cell loss,even before diabetes onset."

The data indicate that GlycoMark could reflect the integrated assessment of beta-cell function and mass,which is essential for identifying high-risk,asymptomatic patients with prediabetes.Eric Button,Precision Diabetes,Inc. CEO,commented,"There is a significant clinical need for a biomarker which can accurately measure beta-cell functional mass. A new marker for beta-cell functional mass has the potential to not only prevent diabetes but also transform the way we treat type 2 diabetes,allowing for a more targeted and personalized treatment approach."

Recently published studies also validate the association of 1,5-anhydroglucitol with beta-cell function and mass:
