It has been revealed that under diabetic conditions oxidative stress is provoked and expression levels of insulin gene transcription factors and incretin receptors are down-regulated which are closely associated with β-cell glucose toxicity. We showed that expression levels of these factors were preserved by reducing glucose toxicity with SGLT2 inhibitor. In addition, we showed that it was more beneficial to use incretin-based drugs at an early stage of diabetes when incretin receptor expression was preserved in β-cells. Similarly, we showed that expression levels of incretin receptors in arterial cells were down-regulated which seemed to be associated with the progression of atherosclerosis. Imeglimin is a relatively new anti-diabetic drug and has been used in clinical practice. Recently we have reported that imeglimin exerts beneficial effects on mitochondria morphology in β-cells and/or number and quality of insulin granules. In addition, we have reported that imeglimin shows favorable effects against the development of atherosclerosis independently of glycemic and lipid control. Taken together, it is likely that augmentation of oxidative stress and decreased expression levels of insulin gene transcription factors and incretin receptors are closely associated with pancreatic β-cell glucose toxicity.

An old report from a single hospital in Africa showed an incidence of 3.5% among 491 insulin-treated individuals. Although the precise pathophysiology remains uncertain, proposed mechanisms include insulin-induced sodium retention, increased vascular permeability, and dysregulation of the renin-angiotensin-aldosterone system. Insulin edema has been described in both type 1 and type 2 diabetes; however, occurrence in slowly progressive type 1 diabetes mellitus (SPIDDM) is exceptionally rare. We report a woman with SPIDDM who developed bilateral lower-leg edema shortly after starting basal-bolus insulin therapy with insulin aspart and insulin degludec. She exhibited no signs of heart failure, liver disease, renal impairment, or allergic reaction to insulin. Cardiac function was normal on echocardiography, and B-type natriuretic peptide levels were within the reference range. She experienced marked edema and an approximately 7-kg weight gain after insulin initiation. Following modification of the insulin regimen and dietary sodium restriction (8 g/day of salt), the edema resolved rapidly within nine days without the use of diuretics. This case illustrates that insulin edema can occur even in individuals with SPIDDM. The observed improvement after insulin regimen adjustment likely reflects the combined influence of glycemic stabilization, fluid-electrolyte balance, and potential formulation-related factors, rather than a direct causal difference between insulin types. Clinicians should recognize this rare yet clinically important complication and adopt an individualized management approach that includes careful glycemic correction and, when appropriate, adjustment of the insulin regimen.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13340-025-00864-4.</p>","PeriodicalId":11340,"journal":{"name":"Diabetology International","volume":"17 1","pages":"13"},"PeriodicalIF":1.2,"publicationDate":"2025-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12748414/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145877646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
