The glomerulus is the primary site of injury in DKD progression. Pathologically, the integrity of the glomerular filtration barrier is disrupted, characterized by podocyte process fusion and detachment, glomerular basement membrane thickening, and reduction of the endothelial cell glycocalyx. These disruptions result in albuminuria due to impaired function of glomerular selective filtration. Additionally, mesangial expansion driven by mesangial cell proliferation and excessive mesangial matrix accumulation in glomeruli is a hallmark of the disease, leading to nodular sclerosis and glomerulosclerosis eventually. Multiple molecular mechanisms involving abnormal metabolism of nutrients, oxidative stress, inflammation, and hyperactivity of the renin-angiotensin system contribute to glomerular pathophysiological changes and renal function deterioration in diabetes mellitus. This review focuses on disturbances in nutrient metabolism and their roles in the pathophysiology of glomerular impairments. Blood glucose control, cardiovascular risk factors intervention, blood pressure management, and renin-angiotensin system blockade are pivotal in preventing the development and progression of DKD.

Risk factors were calculated by population attributable fractions.</p><p><strong>Results: </strong>In 2019, the ASIR, ASMR, and ASDR of CKD in AYAs were 32.21 (95% uncertainty interval [UI], 23.73-40.81) per 100,000, 2.86 (2.61-3.11) per 100,000 and 236.85 (209.03-268.91) per 100,000, respectively. The ASIR was higher among females than males, whereas the ASMR was higher among males than females in 2019. From 1990 to 2019, significant increases in ASIR were found for CKD (EAPC, 0.98%; 95% confidence interval [CI], 0.95%-1.01%), although the ASMR had decreased (EAPC, -0.40%; 95% CI, -0.56% to -0.24%). The largest increase in ASIR was observed in countries with a middle sociodemographic index (SDI) (EAPC, 1.30%; 95% CI, 1.28%-1.33%), while the largest increase in ASMR was observed in high SDI. Globally, the proportional contribution of risk factors for CKD mortality varied across regions, with the highest proportions of high fasting plasma glucose being 14.04% in low SDI, compared with 24.01% in high SDI.</p><p><strong>Conclusion: </strong>CKD is a growing global health problem in AYAs, especially in countries with a middle SDI. Targeted measures are needed to address the rising burden of CKD in AYAs, focusing on prevention, early diagnosis, and reducing disparities.</p>","PeriodicalId":17716,"journal":{"name":"Kidney Research and Clinical Practice","volume":" ","pages":"588-601"},"PeriodicalIF":2.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12245566/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141734498","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}
