The results of the Diabetes Control and Complications Trial-Epidemiology of Diabetes Interventions and Complications (DCCT-EDIC) study have strengthened the 'glycaemic memory' concept, postulating that the quality of metabolic control over several years predicts the development of diabetic complications. To mirror long-term metabolic control, the degree of glycated haemoglobin (HbA) might not represent the optimal biomarker. Other substances with a longer persistence, like the so-called advanced glycation end-products (AGEs), which probably form the substrate of the glycaemic memory, might perform better. Newly developed methods such as the assessment of skin autofluorescence (SAF), enable fast, uncomplicated and non-invasive AGEs assessment. SAF was validated for diabetes screening and shows a good predictive value for the development of diabetic and cardiovascular complications. This article deals with the theoretical background and with available clinical data on this new variable.
糖尿病控制与并发症试验-糖尿病干预与并发症流行病学(DCCT-EDIC)研究结果强化了“血糖记忆”概念,该概念假定数年的代谢控制质量可预测糖尿病并发症的发生。为反映长期代谢控制情况,糖化血红蛋白(HbA)水平可能并非最佳生物标志物。其他具有更长存留时间的物质,如所谓的晚期糖基化终产物(AGEs),可能构成血糖记忆的底物,或许表现更佳。新开发的方法,如皮肤自发荧光(SAF)评估,可实现快速、简便且无创的AGEs评估。SAF已被验证可用于糖尿病筛查,且对糖尿病及心血管并发症的发生具有良好的预测价值。本文探讨了这一新变量的理论背景及现有临床数据。
