Type 1 Diabetes (T1D) is a heterogeneous autoimmune disease with multiple endotypes, each demonstrating distinct clinical and immunological characteristics. Teplizumab, an anti-CD3 monoclonal antibody, has emerged as a promising immunomodulatory therapy capable of delaying the progression of T1D in individuals with stage 2 disease. However, variability in therapeutic response suggests that certain endotypes may derive greater benefit from treatment. This review evaluates the suitability of different T1D endotypes (T1DE) for teplizumab prevention trials, with a particular focus on early-onset T1DE1 and T1DE2. Clinical trials demonstrate that individuals under 15 years of age, who demonstrate the highest immune activity, marked by aggressive T-cell infiltration and rapid pancreatic β-cell destruction, experience the most significant delay in disease progression following teplizumab treatment, highlighting the importance of early intervention. Furthermore, shifting individuals from the rapidly progressing T1DE1 trajectory to the more gradual T1DE2 course may extend functional insulin production and improve long-term metabolic outcomes. This paper underscores the need for expanded endotype-specific prevention trials and optimised screening protocols to identify high-risk individuals at the earliest stage. Future research should explore teplizumab's efficacy in younger populations and refine predictive biomarkers to enhance personalised intervention strategies in T1D management.

1型糖尿病（T1D）是一种具有多种内型的异质自身免疫性疾病，每种内型都表现出不同的临床和免疫学特征。Teplizumab是一种抗cd3单克隆抗体，已成为一种有前景的免疫调节疗法，能够延缓2期T1D患者的进展。然而，治疗反应的可变性表明某些内型可能从治疗中获得更大的益处。本综述评估了不同T1D内型（T1DE）在teplizumab预防试验中的适用性，特别关注早发性T1DE1和T1DE2。临床试验表明，15岁以下的个体表现出最高的免疫活性，以侵略性t细胞浸润和快速胰腺β细胞破坏为特征，在接受teplizumab治疗后，疾病进展的延迟最为显著，突出了早期干预的重要性。此外，将个体从快速发展的T1DE1轨迹转变为更缓慢的T1DE2过程可能会延长功能性胰岛素的产生并改善长期代谢结果。这篇论文强调了扩大内源性特异性预防试验和优化筛选方案的必要性，以便在早期阶段识别高风险个体。未来的研究应该探索teplizumab在年轻人群中的疗效，并完善预测性生物标志物，以增强T1D管理的个性化干预策略。

Background

The atherogenic index of plasma (AIP) is recognized as a robust predictor of cardiovascular outcomes and diabetes incidence. However, no studies have comprehensively investigated the impact of baseline AIP levels and longitudinal AIP trajectories on diabetes progression in patients with prediabetes.

Methods

After data inclusion and exclusion, this retrospective cohort study included 16,411 patients with prediabetes undergoing ≥3 health examinations (2019–2024). Latent Class Trajectory Modeling characterized longitudinal AIP trajectory patterns, and Cox proportional-hazards models evaluated associations of baseline AIP quartiles and trajectory groups with diabetes progression.

Results

During a mean 4-year follow-up (65,644 person-years), 14.14 % patients with prediabetes (2320) progressed to diabetes. Baseline AIP quartiles showed a graded relationship with diabetes progression risk. Three AIP trajectories were identified: the low plateau trajectory (N = 4422, 26.95 %), the medium decreasing trajectory (N = 8183, 49.86 %), and the high decreasing trajectory (N = 3806, 23.19 %). Compared to the low plateau trajectory, the medium decreasing trajectory, and the high decreasing trajectory exhibited progressively elevated diabetes risk in the fully adjusted model (HR = 1.42, 95 % CI: 1.22–1.65 and HR = 2.26, 95 % CI: 1.81–2.83, respectively).

Conclusion

Patients with higher baseline AIP and higher trajectories are associated with higher risks for the progression from prediabetes to diabetes.

血浆动脉粥样硬化指数（AIP）被认为是心血管结局和糖尿病发病率的可靠预测指标。然而，目前还没有研究全面调查基线AIP水平和纵向AIP轨迹对糖尿病前期患者糖尿病进展的影响。方法经资料纳入和排除后，本回顾性队列研究纳入了16,411例接受≥3次健康检查的糖尿病前期患者（2019-2024年）。潜在类别轨迹模型表征了纵向AIP轨迹模式，Cox比例风险模型评估了基线AIP四分位数和轨迹组与糖尿病进展的关系。结果在平均4年的随访期间（65,644人年），14.14%的糖尿病前期患者（2320人）进展为糖尿病。基线AIP四分位数与糖尿病进展风险呈分级关系。AIP有3种轨迹：低平台轨迹（N = 4422, 26.95%）、中等下降轨迹（N = 8183, 49.86%）和高下降轨迹（N = 3806, 23.19%）。与低平台轨迹相比，中度下降轨迹和高下降轨迹在完全调整模型中表现出逐渐升高的糖尿病风险（HR = 1.42, 95% CI: 1.22-1.65, HR = 2.26, 95% CI: 1.81-2.83）。结论基线AIP越高，病程越长，糖尿病前期发展为糖尿病的风险越高。

Aim

To investigate the association between HbA1c and white blood cell (WBC) counts with diabetic macular edema (DME) in type 2 diabetes (T2DM).

Methods

The study was registered on PROSPERO (registration number: CRD42024523016). A comprehensive literature search was conducted on PubMed and EMBASE up to May 2024, including studies investigating HbA1c and WBC counts in patients with T2DM, with and without DME. Standardized mean differences (SMD) and odds ratios (OR) with 95 % confidence intervals (CI) were calculated. A random-effects model was used to pool data. Risk of bias was evaluated using the Newcastle-Ottawa Scale.

Results

Forty-eight studies involving 207,536 participants were included. Egger's test indicated a significant publication bias among studies reporting HbA1c as OR 95 %CI. Pooled results showed that higher HbA1c may increase DME risk (SMD = 0.29, 95 %CI: 0.17 to 0.41; OR = 1.32, 95 %CI: 1.19 to 1.48). Although the same cohort, subgroup analyses found no associations between HbA1c and center-involved DME (SMD = 0.3, 95 %CI: -0.08 to 0.53) or DME development in severe non-proliferative diabetic retinopathy (NPDR)/PDR (SMD = -0.14, 95 %CI: -0.37 to 0.09). In contrast, lower lymphocyte count was significantly associated with DME (SMD = -0.24, 95 %CI: -0.45 to -0.03).

Conclusions

Higher HbA1c and lower lymphocyte count may increase DME risk in T2DM, suggesting potential roles of hyperglycemia and systemic inflammation in its etiology. However, substantial heterogeneity and publication bias warrant cautious interpretation. Future research should clarify the causal role of systemic inflammation through longitudinal studies and investigate DME across different DR stages and diagnostic criteria.

目的探讨2型糖尿病（T2DM）患者糖化血红蛋白（HbA1c）和白细胞（WBC）计数与糖尿病黄斑水肿（DME）的关系。方法本研究在PROSPERO注册（注册号：CRD42024523016）。到2024年5月，我们在PubMed和EMBASE上进行了全面的文献检索，包括研究T2DM患者的HbA1c和WBC计数，伴有和不伴有DME。计算95%置信区间（CI）的标准化平均差（SMD）和比值比（OR）。随机效应模型用于汇集数据。偏倚风险采用纽卡斯尔-渥太华量表进行评估。结果共纳入48项研究，共207,536名受试者。Egger的检验表明，报告HbA1c的研究有显著的发表偏倚，OR 95% CI。综合结果显示，较高的HbA1c可能增加DME的风险（SMD = 0.29, 95% CI: 0.17 ~ 0.41; OR = 1.32, 95% CI: 1.19 ~ 1.48）。在同一队列中，亚组分析发现HbA1c与中心相关性DME （SMD = 0.3, 95% CI: -0.08至0.53）或重度非增生性糖尿病视网膜病变(NPDR)/PDR （SMD = -0.14, 95% CI: -0.37至0.09）之间没有关联。相比之下，较低的淋巴细胞计数与DME显著相关（SMD = -0.24, 95% CI: -0.45至-0.03）。结论较高的HbA1c和较低的淋巴细胞计数可能增加T2DM患者DME的风险，提示高血糖和全身性炎症在其病因中可能起作用。然而，实质性的异质性和发表偏倚值得谨慎解释。未来的研究应通过纵向研究阐明全身性炎症的因果作用，并调查不同DR分期和诊断标准的DME。

Aims

To update evidence on the relationship between dipeptidyl peptidase-4 (DPP-4) inhibitors and incident diabetic retinopathy (DR) in type 2 diabetes.

Methods

We searched Embase, PubMed, Web of Science, and ClinicalTrials.gov (to July 2025) for randomized controlled trials (RCTs) and pooled odds ratios (ORs) with 95 % credible intervals (CrIs) using a Bayesian network meta-analysis. Network meta-regression assessed estimated effect modification; a model-based network meta-analysis (MBNMAdose) evaluated dose–response. Evidence certainty was appraised with Confidence in Network Meta-Analysis (CINeMA).

Results

Forty-three trials (74,546 participants; 779 DR events) were analyzed. No DPP-4 inhibitor significantly changed the DR risk versus placebo (ORs ranged from 0.31 [omarigliptin] to 2.31 [saxagliptin]; all CrIs crossed 1.0). Rankings suggested omarigliptin as most favorable, alogliptin/linagliptin/sitagliptin intermediate, and saxagliptin/teneligliptin least favorable. Baseline DR incidence moderated treatment effects; other prespecified covariates were not significant. MBNMAdose showed no dose-response relationship for DR.

Conclusions

Current randomized evidence indicates class-level neutrality of DPP-4 inhibitors on DR incidence, with no dose–response signal. Choice among gliptins may therefore be guided primarily by glycemic efficacy, safety, and participant characteristics rather than retinal risk.

目的研究二肽基肽酶-4 （DPP-4）抑制剂与2型糖尿病视网膜病变（DR）之间关系的最新证据。方法：我们检索Embase、PubMed、Web of Science和ClinicalTrials.gov（截至2025年7月）的随机对照试验（rct），并使用贝叶斯网络元分析合并95%可信区间（CrIs）的优势比（ORs）。网络元回归评估估计效果修正；基于模型的网络荟萃分析（MBNMAdose）评估了剂量-反应。证据确定性用网络元分析（CINeMA）的置信度评价。结果共纳入43项试验（74,546例受试者，779例DR事件）。与安慰剂相比，DPP-4抑制剂没有显著改变DR风险（ORs范围为0.31[奥马格利汀]至2.31[沙格列汀]；所有CrIs均超过1.0）。排名显示奥马格列汀最有利，阿格列汀/利格列汀/西格列汀中间，沙格列汀/替尼格列汀最不利。基线DR发生率调节治疗效果；其他预先指定的协变量不显著。结论目前的随机证据表明，DPP-4抑制剂对DR发病率的影响是类水平中性的，不存在剂量-反应信号。因此，格列汀类药物的选择可能主要以血糖功效、安全性和受试者特征为指导，而不是视网膜风险。

Aim

To evaluate the clinical efficacy and explore the potential mechanisms of novel mineralocorticoid receptor antagonists (MRAs) in reducing the risk of major adverse cardiovascular events (MACE) in patients with type 2 diabetes mellitus (T2DM).

Methods

Randomized controlled trials (RCTs), including relevant subgroup analyses, of steroidal MRAs (eplerenone, canrenone) and non-steroidal MRAs (finerenone, esaxerenone) in T2DM patients were identified through systematic searches of English and Chinese databases. Meta-analysis was performed to assess clinical outcomes, and network pharmacology was used to explore underlying molecular mechanisms.

Result

18 RCTs (including relevant subgroup analyses) involving 30,103 participants were included. MRAs significantly reduced MACE risk (OR = 0.81, 95 % CI: 0.75–0.86; P < 0.00001). MRAs also significantly decreased cardiovascular mortality (OR = 0.86, 95 % CI: 0.77–0.97; P = 0.01) and hospitalization for heart failure (OR = 0.77, 95 % CI: 0.68–0.87; P < 0.0001). Network pharmacology identified that steroidal MRAs mainly act via IL-17 and relaxin signaling pathways, targeting MAPK10, GSK3B, PTGS2, NOS2, and MMP1. Non-steroidal MRAs primarily modulate Ras and relaxin pathways, involving targets such as EGFR and PIK3C.

Conclusions

This study provides high-certainty evidence supporting MRAs in reducing MACE and heart failure hospitalization, and moderate-certainty evidence for benefits on cardiovascular mortality. Cardioprotective effects may involve Ras, IL-17, and relaxin signaling.

目的评价新型矿皮质激素受体拮抗剂（MRAs）降低2型糖尿病（T2DM）患者主要不良心血管事件（MACE）风险的临床疗效并探讨其潜在机制。方法通过系统检索中英文数据库，对2型糖尿病患者的甾体MRAs （eplerenone、canrenone）和非甾体MRAs （finerenone、esaxerenone）进行随机对照试验（rct），并进行亚组分析。meta分析用于评估临床结果，网络药理学用于探索潜在的分子机制。结果共纳入18项随机对照试验（含相关亚组分析），共纳入30103名受试者。MRAs显著降低MACE风险（OR = 0.81, 95% CI: 0.75-0.86; P < 0.00001）。MRAs还显著降低心血管死亡率（OR = 0.86, 95% CI: 0.77 - 0.97; P = 0.01）和心力衰竭住院率（OR = 0.77, 95% CI: 0.68-0.87; P < 0.0001）。网络药理学发现甾体MRAs主要通过IL-17和松弛素信号通路起作用，靶向MAPK10、GSK3B、PTGS2、NOS2和MMP1。非甾体MRAs主要调节Ras和松弛素通路，涉及EGFR和PIK3C等靶点。结论：本研究提供了高确定性证据支持MRAs降低MACE和心力衰竭住院率，中等确定性证据支持MRAs对心血管死亡率的益处。心脏保护作用可能涉及Ras、IL-17和松弛素信号。

Diabetes mellitus, a chronic metabolic disorder characterized by hyperglycemia, has become a global health issue. The disease primarily presents as type 1 diabetes (T1D), caused by autoimmune β-cell destruction; type 2 diabetes (T2D), driven by insulin resistance and β-cell dysfunction; and monogenic diabetes, resulting from single-gene mutations affecting insulin production or β-cell function. Chronic hyperglycemia increases the risk of severe complications, including cardiovascular disease, neuropathy, and kidney failure. Despite advancements in insulin therapy and glucose monitoring, no cure currently exists for diabetes, with treatments mainly focused on managing symptoms rather than addressing the underlying β-cell loss. Regenerative medicine offers new hope, particularly through β-cell replacement strategies such as islet and stem cell-derived β-cell transplantation. Advances in generating hypoimmunogenic stem cell-derived pancreatic β-cells may help overcome immune rejection and donor shortages. These therapies have shown promise in clinical trials for both T1D and T2D. Furthermore, pharmacological strategies targeting β-cell regeneration show promise in enhancing β-cell proliferation and function. This review highlights the significant advancements in regenerative approaches for diabetes, underscoring the potential for long-term management and, ultimately, a cure for diabetes in the future.

糖尿病是一种以高血糖为特征的慢性代谢性疾病，已成为一个全球性的健康问题。该疾病主要表现为1型糖尿病（T1D），由自身免疫β细胞破坏引起；2型糖尿病（T2D），由胰岛素抵抗和β细胞功能障碍驱动；单基因糖尿病，由影响胰岛素产生或β细胞功能的单基因突变引起。慢性高血糖会增加严重并发症的风险，包括心血管疾病、神经病变和肾衰竭。尽管胰岛素治疗和血糖监测取得了进步，但目前还没有治愈糖尿病的方法，治疗主要集中在控制症状，而不是解决潜在的β细胞损失。再生医学提供了新的希望，特别是通过β细胞替代策略，如胰岛和干细胞衍生的β细胞移植。产生低免疫原性干细胞衍生的胰腺β细胞的进展可能有助于克服免疫排斥和供体短缺。这些疗法在T1D和T2D的临床试验中都显示出了希望。此外，靶向β细胞再生的药理策略显示出增强β细胞增殖和功能的希望。这篇综述强调了再生方法治疗糖尿病的重大进展，强调了长期治疗的潜力，并最终在未来治愈糖尿病。

The effects of a 12-week lifestyle intervention on incretin response during an oral glucose tolerance test in Latino youth with obesity and impaired glucose tolerance 12周生活方式干预对拉丁裔肥胖和糖耐量受损青年口服糖耐量试验中肠促胰岛素反应的影响

Gastric inhibitory polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), the two incretin hormones, play an important pathophysiological role in glucose homeostasis with insulinotropic effects on the pancreatic β-cells. While two previous studies in youth have examined the effects of a lifestyle intervention on incretin concentrations, neither study focused on improvements in glycemic status or oral glucose tolerance test (OGTT)-derived biomarkers. Therefore, we aimed to examine changes in the incretin responses during an OGTT before and after a 12-week lifestyle intervention in Latino youth with obesity and impaired glucose tolerance (IGT). A total of 9 Latino youth with obesity and IGT underwent a two-hour OGTT with 30-min blood samples collected for the measurement of glucose, insulin, and incretin hormones before and after the lifestyle intervention (nutrition education and 180 min of moderate-vigorous exercise weekly for a total of 12 weeks). From pre- to post-intervention, a trend towards reduction was observed in the total GIP area under the curve (AUC) during the OGTT (5499.1 ± 715.3 vs. 4085.2 ± 389.5 pg/mL, p = 0.059), with no change in GLP-1. Moreover, BMI%, glucose AUC, and two-hour glucose concentrations were significantly reduced after the intervention. Our data suggest that a lifestyle intervention in Latino youth with obesity and IGT could influence incretin and glucose metabolism. Future studies should examine if the GIP response to a lifestyle intervention is mediated by baseline glycemic status.

胃抑制多肽（GIP）和胰高血糖素样肽-1 （GLP-1）是两种肠促胰岛素激素，在葡萄糖稳态中起重要的病理生理作用，对胰腺β细胞具有促胰岛素作用。虽然之前有两项针对年轻人的研究考察了生活方式干预对肠促胰岛素浓度的影响，但这两项研究都没有关注血糖状态的改善或口服葡萄糖耐量试验（OGTT）衍生的生物标志物。因此，我们的目的是研究肥胖和糖耐量受损（IGT）的拉丁裔青年在12周生活方式干预前后OGTT中肠促胰岛素反应的变化。共有9名患有肥胖和IGT的拉丁裔青年接受了两个小时的OGTT，并在生活方式干预（营养教育和每周180分钟的中等剧烈运动，共12周）前后采集了30分钟的血液样本，用于测量葡萄糖、胰岛素和肠促胰岛素激素。从干预前到干预后，OGTT期间总GIP曲线下面积（AUC）有降低的趋势（5499.1±715.3 vs 4085.2±389.5 pg/mL, p = 0.059）， GLP-1无变化。此外，干预后BMI%、葡萄糖AUC和两小时葡萄糖浓度显著降低。我们的数据表明，对肥胖和IGT的拉丁裔青年进行生活方式干预可能会影响肠促胰岛素和葡萄糖代谢。未来的研究应该检查GIP对生活方式干预的反应是否由基线血糖状态介导。
