Although the numbers of patients with frailty, dementia, disability, and/or multimorbidity are increasing worldwide, the accumulated evidence on the safe and effective treatment of these populations remains insufficient. Older patients, especially those older than 75 years old, are often underrepresented in randomized controlled trials of various treatment effects, resulting in limited clinical evidence for this population.

Insulin secretory capacity was assessed based on fasting serum C-peptide concentration (CPR) and C-peptide index (CPI) in all subjects, while insulin resistance in non-insulin users (<i>n</i> = 312) was determined using the homeostasis model assessment of insulin resistance (HOMA-IR) index.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Median values for CPR and CPI in all subjects were 2.4 ng/mL and 1.5, respectively, while that for HOMA-IR in non-insulin users was 3.2. The XOR inhibitor users (<i>n</i> = 72) had significantly (<i>P</i> < 0.001) higher CPR and CPI levels than non-users (<i>n</i> = 356). Multivariable regression analyses showed XOR inhibitor use was positively associated with CPR (β = 0.153, <i>P</i> = 0.001) and CPI (β = 0.144, <i>P</i> = 0.001). Similar results were observed in propensity score analyses. In subgroup analyses of patients with a preserved estimated glomerular filtration rate (≥60 mL/min/1.73 m<sup>2</sup>) and non-insulin users, these associations remained significant. Furthermore, the associations were significant in patients with lower (≤6.0 mg/dL) but not with higher (>6.0 mg/dL) uric acid levels (<i>P</i> for interaction <0.05). On the other hand, XOR inhibitor use showed no significant association with HOMA-IR.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The results of XOR inhibitor treatment, especially a sufficient reduction in serum uric acid level, may provide protective effects on insulin secretory capacity in patients with type 2 diabetes.</p>\u0000 </section>\u0000 </div>","PeriodicalId":51250,"journal":{"name":"Journal of Diabetes Investigation","volume":"15 10","pages":"1500-1509"},"PeriodicalIF":3.1,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11442858/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141791393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
