Special Issue Information

Dear Colleagues,

Diabetic Bone Disease (DBD) is an emerging complication in Diabetes Mellitus (DM), characterized by alterations in bone metabolism and increased fracture risk. The pathophysiology of DBD involves a complex interplay between hyperglycaemia, insulin deficiency or resistance, and advanced glycation end-products (AGEs) that impair bone quality and remodelling. Therapeutic management of DBD requires a multifaceted approach, which is often challenging, including stringent glycaemic control, lifestyle modifications, and pharmacological interventions. Multidisciplinary care involving endocrinologists, orthopaedic specialists, and dietitians is essential for optimal management. As research advances, a deeper understanding of DBD’s molecular mechanisms will likely yield new therapeutic targets, improving patient outcomes and quality of life.

This Special Issue aims to focus on new insights, novel developments and discoveries, current challenges, and future perspectives in the field of Diabetic Bone Disease to and provide a comprehensive update.

We invite basic, clinical, and translational researchers in relevant fields to submit original research articles, literature reviews, systematic reviews, and hypothesis-driven papers addressing important issues such as, but not limited to, the following:

  • New advances in understanding the pathophysiological mechanisms that drive DBD.
  • How antidiabetic interventions affect bone metabolism via studying alterations in bone biochemical markers, BMD, fracture risk, etc.
  • Utilisation of in vitro models to elucidate bone cell behaviour and molecular changes in a hyperglycaemic environment.
  • Identification of bone microarchitecture alterations in Diabetes.

Diabetic bone disease (DBD) is a frequent complication in patients with type 2 diabetes mellitus (T2DM), characterised by altered bone mineral density (BMD) and bone turnover marker (BTMs) levels. The impact of different anti-diabetic medications on the skeleton remains unclear, and studies have reported conflicting results; thus, the need for a comprehensive systematic review is of paramount importance. A systematic search was conducted in PubMed and the Cochrane Library. The primary outcomes assessed were changes in BMD in relation to different anatomical sites and BTMs, including mainly P1NP and CTX as well as OPG, OCN, B-ALP and RANK-L. Risk of bias was evaluated using the JADAD score. The meta-analysis of 19 randomised controlled trials comprising 4914 patients showed that anti-diabetic medications overall increased BMD at the lumbar spine (SMD: 0.93, 95% CI [0.13, 1.73], p = 0.02), femoral neck (SMD: 1.10, 95% CI [0.47, 1.74], p = 0.0007) and in total hip (SMD: 0.33, 95% CI [−0.25, 0.92], p = 0.27) in comparison with placebo, but when compared with metformin, the overall effect favoured metformin over other treatments (SMD: −0.23, 95% CI [−0.39, −0.07], p = 0.004). GLP-1 receptor agonists and insulin analogues seem to improve BMD compared to placebo, while SGLT2 inhibitors and thiazolidinediones (TZDs) showed no significant effect, although studies’ number cannot lead to safe conclusions. For BTMs, TZDs significantly increased P1NP levels compared to placebo. However, no significant differences were observed for CTX, B-ALP, OCN, OPG, and RANK-L between anti-diabetic drugs and metformin or placebo. High heterogeneity and diverse follow-up durations among studies were evident, which obscures the validity of the results. This review highlights the variable effects of anti-diabetic drugs on DBD in T2DM patients, emphasising the need for long-term trials with robust designs to better understand these relationships and inform clinical decisions.
