Oltre i target glicemici: effetto legacy e variabilità glicemica nelle complicanze del diabete
摘要
Diabetes mellitus poses an escalating challenge among non-communicable diseases, with substantial socioeconomic burden driven by diabetes-related complications (DRCs). This comprehensive review explores the legacy effect and glycaemic variability (GV) impact on chronic diabetic complications. Evidence shows that intensive glycaemic control significantly reduces microvascular complications, with sustained benefits persisting beyond the intervention period (legacy effect). Multiple GV parameters have emerged as independent predictors of diabetic complications, including long-term measures (HbA1c variability) and short-term metrics (MAGE, TIR, MODD). Studies consistently show that higher GV correlates with increased risk of retinopathy, nephropathy, and cardiovascular events, independent of mean glucose levels. The clinical implications suggest that comprehensive diabetes management should incorporate both pursuing strict glycaemic targets in early stages of diabetes and glycaemic variability reduction strategies to optimise long-term outcomes and minimise DRC burden.
