Bone fragility is increasingly recognized as a relevant complication of type 2 diabetes (T2D) and diabetic patients with fragility fractures have higher mortality rates than non diabetic individuals or diabetic patients without fractures. However, current diagnostic approaches for fracture risk stratification, such as bone mineral density measurement or the use of risk assessment algorithms, largely underestimate fracture risk in T2D patients. A multidisciplinary expert panel was established in order to in order to formulate clinical consensus recommendations on bone health assessment and management of fracture risk in patients with T2D.
The following key questions were addressed: a) which are the risk factors for bone fragility in T2D?, b) which diagnostic procedures can be currently used to stratify fracture risk in T2D patients?, c) which are the effects of antidiabetic treatments on bone?, and d) how to prevent and treat bone fragility in T2D patients? Based on the available data members of this panel suggest that the stratification of fracture risk in patients with diabetes should firstly rely on the presence of a previous fragility fracture and on the individual risk profile, with the inclusion of T2D-specific risk factors (namely T2D duration above 10 yrs, presence of chronic T2D complications, use of insulin or thiazolidinediones and persistent HbA1c levels above 8% for at least 1 year). Two independent diagnostic approaches were then suggested in the presence or the absence of a prevalent fragility fracture, respectively.
Clinical trials in T2D patients at risk for fragility fractures are needed to determine the efficacy and safety of available antiresorptive and anabolic agents in this specific setting.
骨脆性越来越被认为是 2 型糖尿病(T2D)的一个相关并发症,脆性骨折的糖尿病患者死亡率高于非糖尿病患者或无骨折的糖尿病患者。然而,目前用于骨折风险分层的诊断方法,如骨密度测量或使用风险评估算法,在很大程度上低估了 T2D 患者的骨折风险。成立了一个多学科专家小组,以制定关于 T2D 患者骨健康评估和骨折风险管理的临床共识建议。
针对以下关键问题进行了讨论:a)T2D 患者骨脆性的危险因素有哪些?b)目前可用于分层 T2D 患者骨折风险的诊断程序有哪些?c)抗糖尿病治疗对骨骼的影响有哪些?d)如何预防和治疗 T2D 患者的骨脆性?根据现有数据,该小组的成员建议,糖尿病患者的骨折风险分层首先应依赖于先前的脆性骨折和个体风险状况,包括 T2D 特异性危险因素(即 T2D 病程超过 10 年、存在慢性 T2D 并发症、使用胰岛素或噻唑烷二酮以及 HbA1c 水平持续超过 8%至少 1 年)。然后在存在或不存在常见脆性骨折的情况下,分别提出了两种独立的诊断方法。
需要在有脆性骨折风险的 T2D 患者中进行临床试验,以确定现有抗吸收和合成代谢药物在这种特定情况下的疗效和安全性。
