1, 5-Anhydroglucitol as Marker of Short-Term Hyperglycemic Excursions in Well-Controlled Type 2 Diabetes Mellitus: Associations with the Prevalence of Vascular Complications

The importance of an appropriate and stable long-term mean glycemic control, commonly measured by the HbA1c, for the incidence of diabetic complications has been widely recognized [1–4]. The HbA1c reflects the glycemic metabolism of the past 2-3 months and can therefore be recognized as longterm glycemic marker. In contrast, it is only slightly influenced by short-term glycemic excursions, e.g. states of postprandial hyperglycemia. However, short-term excursions also seem to exhibit pathogenetic significance for the development of vascular complications [5–8].
