摘要:

目的 探讨2型糖尿病(T2DM)患者甲状腺反馈分位指数(TFQI)、促甲状腺激素指数(TSHI)、促甲状腺素抵抗指数(TT4RI)和游离三碘甲状腺原氨酸与游离甲状腺素比值(FT3/FT4)与糖尿病周围神经病变(DPN)之间的关联。 方法 纳入医院在2022年5月至2025年5月期间收治的T2DM患者100例,根据患者是否合并DPN分为DPN组(n = 43)及非DPN组(n = 57),收集患者临床资料并计算甲状腺激素敏感性指标,采用单因素及多因素logistic回归分析T2DM合并DPN的影响因素,应用Spearman相关性分析甲状腺激素敏感性指标与DPN的关系;应用受试者工作特征(ROC)曲线,评估甲状腺激素敏感性相关指标对T2DM合并DPN的预测效能。 结果 DPN组的FT3、TFQI、TSHI、TT4RI、FT3/FT4、感觉神经传导速度(SCV)、运动神经传导速度(MCV)均显著低于非DPN组,年龄高于非DPN组(P < 0.05);多因素logistic回归分析结果显示,TFQI(OR = 0.491,95%CI:0.260 ~ 0.926)、TSHI(OR = 0.594,95%CI:0.387 ~ 0.911)、TT4RI(OR = 0.418,95%CI:0.183~0.954)、FT3/FT4(OR = 0.540,95%CI:0.352 ~ 0.827)为T2DM合并DPN发生的独立影响因素(P < 0.05)。Spearman相关性分析结果显示,TFQI、TSHI、TT4RI、FT3/FT4与DPN呈现显著负相关(r = -0.563、-0.501、-0.541、-0.292,P < 0.05)。ROC曲线分析结果显示,甲状腺激素敏感性各项指标联合预测T2DM合并DPN的曲线下面积(AUC)、特异度及灵敏度分别为0.918、90.70%、93.00%,其中AUC、灵敏度显著高于TFQI、TSHI、TT4RI、FT3/FT4单一指标检测(P < 0.05)。 结论 在T2DM患者中,甲状腺激素敏感性指标的降低与DPN的发生密切相关,且这些指标均为DPN发生的独立影响因素,联合检测有助于提高DPN预测效能。

Abstract:

Objective To investigate the associations of the thyroid feedback quantile-based index (TFQI), the thyroid-stimulating hormone index (TSHI), the thyrotropin resistance index (TT4RI), and the free triiodothyronine/free thyroxine (FT3/FT4) ratio with diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (T2DM). Methods A total of 100 patients with T2DM who were admitted to the hospital from May 2022 to May 2025 were enrolled in this study. Based on the presence or absence of DPN, these patients were divided into the DPN group (n = 43) and the non-DPN group (n = 57). Clinical data were collected, and thyroid hormone sensitivity indices were calculated. The influencing factors for DPN in T2DM were identified through univariate and multivariate logistic regression analyses. The relationship between thyroid hormone sensitivity indices and DPN was explored via Spearman correlation analysis. The predictive efficacy of these indices for DPN in T2DM was evaluated by using the receiver operating characteristic (ROC) curve. Results In comparison with the non-DPN group, the DPN group exhibited significantly lower levels of FT3, TFQI, TSHI, TT4RI, FT3/FT4, motor conduction velocity (MCV), and sensory conduction velocity (SCV). Moreover, patients in the DPN group were older (P < 0.05). Multivariate logistic regression analysis indicated that TFQI (OR = 0.491, 95%CI: 0.260 - 0.926), TSHI (OR = 0.594, 95%CI: 0.387 - 0.911), TT4RI (OR = 0.418, 95%CI: 0.183 - 0.954), and FT3/FT4 (OR = 0.540, 95%CI: 0.352 - 0.827) were independent factors influencing the occurrence of DPN in T2DM (P < 0.05). Spearman correlation analysis demonstrated that TFQI, TSHI, TT4RI, and FT3/FT4 were significantly negatively correlated with DPN (r = -0.563, -0.501, -0.541, -0.292, P < 0.05). ROC curve analysis disclosed that the area under the curve (AUC), specificity, and sensitivity of the combination of thyroid hormone sensitivity indices for predicting DPN in patients with T2DM were 0.918, 90.70%, and 93.00%, respectively. The AUC and sensitivity were significantly higher than those of TFQI, TSHI, TT4RI, or FT3/FT4 when used alone (P < 0.05). Conclusions In patients with T2DM, a decreased sensitivity to thyroid hormone indices is closely related to the occurrence of DPN, and these indices are independent influencing factors for DPN. The combined detection of these indices can improve the predictive efficacy for DPN.
