目的 探讨不同体质指数（BMI）分组成年1型糖尿病（T1DM）患者的临床特征以及超重/肥胖与心血管代谢危险因素之间的关系。方法 纳入2015年6月至2022年6月在广州市第一人民医院内分泌代谢科住院的268例成人T1DM患者。分为超重肥胖组（BMI≥24.0 kg/m²，41例）、体质量正常组（18.5≤BMI＜24.0 kg/m²，155例）和体质量过低组（BMI＜18.5 kg/m²，72例）。比较三组人口学、人体测量及代谢指标的差异，采用多元线性回归分析BMI与估算肾小球滤过率（eGFR）的关联。结果 超重肥胖组患者的特征表现为年龄更大、病程更长、体脂肪量更高、腹部皮下脂肪面积更大、腰围、臀围更大、合并高血压比例更高、收缩压更高、高密度脂蛋白胆固醇更低、eGFR更低、糖化血红蛋白（HbA1c）更低。多元线性回归分析显示，校正年龄、性别、病程后，BMI与eGFR呈负相关（β=-2.050，P=0.012）；进一步校正HbA1c、血压、血脂后，该关联不再显著。结论 超重/肥胖成人T1DM患者存在多重代谢异常聚集，BMI与eGFR的负向关联可能主要与血糖、血压、血脂等代谢因素有关。

Objective To investigate the clinical characteristics of adult patients with type 1 diabetes mellitus（T1DM）in different body mass index（BMI）categories and the associations of overweight and obesity with cardiometabolic risk factors．Methods A total of 268 adult T1DM inpatients from Guangzhou First People’s Hospital were enrolled．Patients were divided into three groups：overweight/obese（BMI≥24.0 kg/m²，n=41），normal-weight（18.5≤BMI＜24.0 kg/m²，n=155），and underweight（BMI＜18.5 kg/m²，n=72）．Demographic characteristics，anthropometric measurements，and metabolic parameters were compared among the three groups．Multivariable linear regression analyses were performed to evaluate the association between BMI and estimated glomerular filtration rate（eGFR）．Results Patients in the overweight/obesity group were characterized by older age，longer diabetes duration，higher body fat mass，larger abdominal subcutaneous fat area，greater waist and hip circumferences，a higher prevalence of hypertension，higher systolic blood pressure，lower high-density lipoprotein cholesterol levels，lower eGFR，and lower glycated hemoglobin（HbA1c）levels．Multivariable linear regression analysis demonstrated that BMI was inversely associated with eGFR after adjustment for age，sex，and diabetes duration（β=-2.050，P=0.012）．However，this association was no longer significant after further adjustment for HbA1c，blood pressure，and lipid parameters．Conclusions Overweight/obese adult T1DM patients exhibit clustering of metabolic abnormalities．The negative association between BMI and eGFR may be primarily mediated by metabolic factors such as hyperglycemia，hypertension，and dyslipidemia．

目的 系统评价胰岛素联用α-葡萄糖苷酶抑制剂(AGIs)治疗成人1型糖尿病(T1DM)的疗效和安全性。方法 检索中英文数据库,纳入关于胰岛素联用AGIs治疗成人T1DM患者的随机或非随机对照试验。使用Review Manager 5.3软件进行Meta分析。结果 共纳入10项研究,616例患者。与安慰剂或空白对照相比,在有效性方面,胰岛素联合AGIs可改善成人T1DM患者的糖化血红蛋白;降低平均血糖、空腹血糖和餐后2小时血糖;改善血糖波动情况,包括平均血糖波动幅度和最大血糖波动幅度(均P<0.05)。在安全性方面,AGIs增加总不良反应发生的风险(P<0.05),其中主要是胃肠道不适,但未增加低血糖的发生率和发生次数(均P>0.05)。胰岛素联合AGIs减少了每日胰岛素总剂量(P<0.05),但对体重、甘油三酯和高密度脂蛋白胆固醇无显著影响(均P>0.05)。结论 胰岛素联合AGIs可降低成人T1DM患者的糖化血红蛋白,改善血糖水平和血糖波动情况。AGIs不会增加低血糖的风险,但需重视其不良反应,特别是胃肠道不良反应。

Objective To systematically evaluate the efficacy and safety of adding alpha-glucosidase inhibitors (AGIs) to insulin therapy in adult patients with type 1 diabetes (T1DM). Methods Articles about randomized or non-randomized controlled trials of insulin combined with AGIs in adult patients with T1DM were retrieved from Chinese and English database. Meta-analyses were performed by using Review Manager 5.3. Results A total of 616 patients were included from 10 clinical trials. Compared with adding placebo or nothing, in terms of efficacy, the addition of AGIs resulted in decreased HbA1c, mean blood glucose, fasting plasma blood glucose and 2-hour postprandial blood glucose levels (all P<0.05). And this scheme improved the glucose variability including mean amplitude of glycemic excursions and the largest amplitude of glycemic excursions (P<0.05, respectively). As to safety, AGIs increased the risk of total adverse reactions (P<0.05), most of them were gastrointestinal complaints, while the occurrence and the frequency of hypoglycemia were similar (P>0.05, respectively). This scheme could also lead to the reduced total daily insulin dose (P<0.05) but had no significant effect on body weight, triglyceride or cholesterol concentration (P>0.05, respectively). Conclusions The addition of AGIs to insulin therapy in adult patients with T1DM may reduce HbA1c and improve the glucose levels and glucose variability. But total adverse effects especially the gastrointestinal complaints should also be considered in the use of AGIs although it does not increase the risk of hypoglycemia.

目的 探讨DPP-4抑制剂西格列汀对成人隐匿性自身免疫性糖尿病(LADA)早期患者胰岛β细胞功能的影响。方法 把14例新诊断为LADA患者随机分为两组,胰岛素治疗100 mg/d西格列汀(A组,n=7)或无西格列汀(B组,n=7)共治疗9个月。结果 9个月后两组之间的血糖和糖化血红蛋白水平无差异。9个月后A组空腹C肽(FCP),餐后C肽(CP),和ΔCP(ΔCP=2 h CP-FCP)水平与基线相比无明显差别(P＞0.05),B组FCP,2 h的CP和ΔCP进行比较基线显著下降(P<0.05)。A组2 h CP水平明显高于B组(P<0.05)。结论 胰岛素与西格列汀联用较单用胰岛素治疗成人隐匿性自身免疫糖尿病早期患者似乎能更好保护胰岛β细胞功能,西格列汀或可延长LADA非胰岛素依赖期的时间。

Objective The Objective of the study was to investigate the effects of the DPP-4 inhibitor on β-cell function in patients with recent-onset latent autoimmune diabetes in adults LADA. Methods Fourteen recently diagnosed LADA patients were randomized into two groups, A and B, to receive insulin therapy with 100 mg/d sitagliptin (group A, n=7) or without sitagliptin (group B, n=7) for 9 months. Results There were no differences in the clinical baseline data between the two groups. During the 9 months of follow-up, there were no significant differences in glucose and glycosylated hemoglobin levels between the two groups. At 9 months, there were not different in group A including fasting C-peptide (FCP), 2-hour postprandial C-peptide (CP), and ΔCP(ΔCP=2 h CP-FCP) levels (P>0.05). Compared with baseline, whereas in group B the levels of FCP, 2-hour CP and ΔCP were significantly decreased compared with baseline (P<0.05). Levels of 2-hour CP were higher in group A, it was higher than group B at 9 months (P<0.05). Conclusion LADA patients treated with sitagliptin and insulin was more likely maintain β-cell function by comparison with insulin alone. Sitagliptin administration in patients with LADA might prolong the insulin-free period.

Objective To observe the efficacy and recurrence rates of mycophenolate mofetil (MMF) on hormone-dependent or steroid-resistant adult minimal change disease (MCD). Methods We retrospectively reviewed the records of adult patients at Shunde district hospital of traditonal Chinese medicine of Foshan for minimal change from February 2011 to August 2013. All patients who were hormone-dependent or steroid-resistant were collected. Twenty-five patients were randomly divided into short or long course group. The patient at short course group was given MMF combined with oral prednisone for 6 months, and the long course group was given for 18 months. Patient demographics, efficacy of medicines and recurrence rates were observed. Results Except one case of the long course group quitting at the second month because of severe infection, the other cases all finished the 18 months of follow up. At the 6 month after therapy with MMF, in both group, the 24h urine protein had lowered significantly (P<0.05) and the serum albumin level had risen remarkably (P<0.05). At the end of the follow up, compared with the 6 month after therapy, the 24 h urine protein of the short course group had increased (P<0.05), while those of the long course group had no obvious difference (P>0.05). At the 6 month after therapy, there were 9 cases achieved complete remission.There was no significant difference between the two groups (χ²=0.372, P>0.05). At the end of the follow up, compared with the 6 month after therapy, there were 6 cases experienced relapse (54.54%) in the short course group and 2 cases of those in the long course group (18.18%), but with no significant difference between them (χ²=0.076, P>0.05). Conclusion MMF can induce the remission of adult MCD efficiently, and its low dose maintenance treatment can decrease recurrence rates.
