The risk of fragility fractures is increased in people with both type 1 and type 2 diabetes. While guidance for the evaluation and management of fracture risk in these patients has been recently proposed by an International Osteoporosis Foundation (IOF) working group, a new review now examines a range of biochemical markers, and considers their potential role in helping clinicians further evaluate fracture risk.
The review ‘ Biochemical Markers of Bone Fragility in Patients with Diabetes ’ has been authored by an expert working group of the International Osteoporosis Foundation (IOF) and the European Calcified Tissue Society (ECTS).
Professor Christian Meier, lead author and Co-Chair of the IOF Bone and Diabetes Working Group, stated:
“Biochemical markers play an important role in the management of osteoporosis, but their role in diabetic bone disease is less clear. The aim of the Working Group was to evaluate the numerous biochemical markers that reflect bone and/or glucose metabolism in type 1 and type 2 diabetes and to identify which of these markers would be most valuable in assessing bone health and fracture risk and guiding patient care in diabetes. In our extensive review of the literature, we looked at the key findings of studies on Bone Turnover Markers (BTMs) and the effects of diabetes medications such as metformin, sulfonylureas, thiazolidinediones, incretin-based therapies, and sodium glucoses co-transporter 2 inhibitors, as well as hormones.”
The review finds:
Professor Serge Ferrari, Co-chair of the IOF Bone and Diabetes Working Group, added:
“This review of biomarkers highlights the importance of low bone turnover in the pathogenesis of diabetic bone disease and points to alterations in bone quality as well to the most promising biochemical markers. Nevertheless, it is clear that further research is needed. So far only glycemic control, AGEs, and serum IGF-1 seem to have the potential for fracture prediction in patients with diabetes. Other biomarkers, such as periostin, which have been associated with bone microstructure and fragility fractures, or circulating dipeptidyl peptidase inhibitor 4, potentially associated with vascular disease in diabetes, are also under investigation.”
Professor Nicholas Harvey, Chair of the IOF Committee of Scientific Advisors, concluded:
“We thank the IOF and ECTS Working Group members for their valuable work and ongoing collaboration. As bone fragility is a substantial concern for individuals with diabetes, identifying which biochemical markers have the most predictive value could have far-reaching implications for the early detection and prevention of bone-related complications in these patients.”
