Both T1DM and T2DM induce chronic hyperglycaemia, leading to the accumulation of advanced glycosylation end products that affect osteoblast function, increased collagen crosslinking and a senescence phenotype promoting inflammation. Together with an increased incidence of microvascular disease and an increased risk of vitamin D deficiency, these factors reduce bone quality, thereby increasing bone fragility. In T1DM, reduced anabolic stimuli as well as the presence of autoimmune conditions might also contribute to reduced bone mass and increased fragility. Diabetes mellitus is the most common cause of kidney failure, and fracture risk is exacerbated when chronic kidney disease (CKD)-related mineral and bone disorders are superimposed on diabetic changes. Microvascular pathology, cortical thinning and trabecular deterioration are particularly prominent in patients with T1DM and CKD, who suffer more fragility fractures than do other patients with CKD. This Review explores the pathophysiology of bone fragility in patients with diabetes mellitus and CKD and discusses techniques to predict fracture and pharmacotherapy that might reduce fracture risk.</p>","PeriodicalId":18916,"journal":{"name":"Nature Reviews Endocrinology","volume":"53 1","pages":""},"PeriodicalIF":40.5,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142986015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, pituitary irAEs and type 1 diabetes mellitus can be lethal if overlooked, potentially leading to adrenal crisis and diabetic ketoacidosis, respectively. On the other hand, pituitary and thyroid irAEs are reported to be associated with more favourable prognoses in some cancers if treated appropriately with hormone-replacement therapies. It would be useful to identify those people who are likely to develop endocrine irAEs before initiating therapy with ICIs.

Changes in insulin signalling and insulin levels are thought to directly explain many of the metabolic abnormalities that occur in diabetes mellitus, such as impaired glucose disposal. However, molecules that are directly affected by abnormal insulin signalling might subsequently go on to cause secondary metabolic effects that contribute to the pathology of type 2 diabetes mellitus. In the past several years, evidence has linked insulin resistance with the concentration, composition and distribution of bile acids. As bile acids are known to regulate glucose metabolism, lipid metabolism and energy balance, these findings suggest that bile acids are potential mediators of metabolic distress in type 2 diabetes mellitus.

Current international guidelines focus on symptomatic management, with little discussion regarding potential medication, as therapeutic options were limited at the time of their publication. Vosoritide is the first pharmacological, precision treatment for achondroplasia; it was approved for use in 2021, creating a need for vosoritide treatment guidelines to support clinicians. An international collaborative of leading experts and patient advocates was formed to develop this Consensus Statement. The group developed the guideline scope and topics during a hybrid meeting in November 2023; guideline statements were subsequently ratified via Delphi methodology using a predefined consensus threshold. These statements provide recommendations across the treatment pathway, from starting treatment with vosoritide through ongoing monitoring and evaluation, to stopping vosoritide and ongoing monitoring following cessation. These guidelines recommend a minimum set of requirements and a practical framework for professionals and health services worldwide regarding the use of vosoritide to treat infants, children and young people with achondroplasia.

In chronic obesity, white adipose tissue undergoes pathological remodelling marked by adipocyte hypertrophy, chronic inflammation and fibrosis, which are linked to local and systemic insulin resistance. Research data suggest that the capacity for healthy or unhealthy white adipose tissue remodelling might depend on the intrinsic diversity of adipose progenitor cells (APCs), which sense and respond to metabolic cues.
