摘要:

目的 探讨早发2型糖尿病(T2DM)患者中血糖变异系数(GCV)与高尿酸血症(HUA)患病风险的关系。 方法 选取2023年9月—2024年11月于本院内分泌科住院的224例T2DM患者作为研究对象。收集研究对象的一般资料、实验室生化指标和长期血糖监测(CGM)相关指标。根据血清中尿酸(SUA)水平将早发T2DM患者进一步分为HUA组和非HUA组。采集空腹静脉血检测研究对象SUA、糖化血红蛋白(HbA1c)、血脂和肝肾功能等指标,通过CGM系统获取研究对象的GCV、目标范围内时间(TIR)和平均血糖波动幅度(MAGE)等血糖波动参数。采用t检验和Mann-Whitney U检验比较患者各指标的组间差异,Spearman相关性分析患者GCV与SUA水平的相关性,修正泊松回归模型分析早发T2DM患者GCV与HUA之间的关联,受试者工作特征(ROC)曲线和曲线下面积(AUC)评估GCV和HbA1c水平对早发T2DM患者并发HUA的预测价值。 结果 早发T2DM组患者的HUA患病率明显高于晚发T2DM组(P<0.001),2组患者年龄、病程、性别、糖尿病家族史、体质量指数(BMI)和血清SUA、丙氨酸氨基转移酶(ALT)及天冬氨酸氨基转移酶(AST)水平比较差异有统计学意义(P<0.05)。早发T2DM患者中,与非HUA组比较,HUA组患者血清中肌酐(Scr)和甘油三酯(TG)水平及动脉硬化指数(AI)、空腹C肽(FC-P)、餐后2小时C肽(2hC-P)、GCV和MAGE均明显升高(P<0.05),患者血清中高密度脂蛋白胆固醇(HDL-C)水平明显降低(P<0.05)。Spearman相关性分析,早发T2DM患者SUA水平与GCV呈正相关关系(r=0.403,P<0.001)。在校正混杂因素后,与GCV最低四分位数组比较,GCV最高四分位数组患者的HUA发生风险明显升高(RR=2.12,P<0.05)。GCV预测早发T2DM患者并发HUA的AUC为0.859(95%CI:0.783~0.935),最佳截断值为58.5%,灵敏度为79.7%,特异度为76.7%。 结论 早发T2DM患者并发HUA比例高于晚发T2DM患者,GCV水平升高与早发T2DM患者HUA患病风险存在明显关联。

Abstract:

Objective To investigate the relationship between the glucose coefficient of variation (GCV) and the risk of hyperuricemia (HUA) in the patients with early-onset type 2 diabetes mellitus (T2DM). Methods A total of 224 hospitalized patients with T2DM between September 2023 and November 2024 were enrolled. The general clinical data, laboratory biochemical indicators, and continuous glucose monitoring (CGM)-derived metrics were collected.The early-onset T2DM patients were stratified into HUA and non-HUA groups based on their serum uric acid (SUA) levels. Fasting venous blood was collected to detect SUA, glycated hemoglobin (HbA1c), blood lipids, liver and kidney function indexes, and other indicators. Glucose variability parameters, including GCV, time in range (TIR), and mean amplitude of glycemic excursions (MAGE), were obtained using the CGM system. The t-test and Mann-Whitney U test were used to compare the differences in the indicators of the patients between various groups; Spearman correlation analysis was used to analyze the correlation between GCV and SUA level in the patients; modified Poisson regression models were used to evaluate the association between GCV and HUA in early-onset T2DM patients; receiver operating characteristic (ROC) curve analysis along with the area under the curve (AUC) were used to determine the predictive values of GCV and HbA1c level for HUA in early-onset T2DM patients. Results The prevalence of HUA in early-onset T2DM group was significantly higher than that in late-onset T2DM group (P<0.001). Significant differences were observed between the patients in two groups in age, disease duration, gender, family history of diabetes, body mass index (BMI) as well as serum levels of SUA, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) (P<0.05). Among early-onset T2DM patients, compared with non-HUA group, the serum levels of creatinine (Scr) and triglyceride(TG), atherogenic index (AI), fasting C-peptide (FC-P), 2-hour postprandial C-peptide (2hC-P), GCV, and MAGE in the patients in HUA group were significantly increased (P<0.05), while the level of high-density lipoprotein cholesterol (HDL-C) was significantly decreased (P<0.05). The Spearman correlation analysis results showed a positive correlation between SUA level and GCV in early-onset T2DM patients (r=0.403, P<0.001). After adjusting for confounding factors, compared with the patients in the lowest GCV quartile, the risk of HUA among those in the highest GCV quartile was significantly increased (RR=2.12,P <0.05). The AUC of GCV for predicting HUA in early-onset T2DM patients was 0.859 (95% CI: 0.783-0.935), with an optimal cutoff value of 58.5%, a sensitivity of 79.7%, and a specificity of 76.7%. Conclusion The proportion of HUA in early-onset T2DM patients is higher than that in late-onset T2DM patients. Increased GCV level is significantly associated with an increased risk of HUA in the patients with early-onset T2DM.
