摘要

摘要: 目的探讨甘油三酯葡萄糖乘积指数(TyG)、TyG联合BMI及TyG联合腰围(WC)预测阻塞性睡眠呼吸暂停(OSA)患者发生非酒精性脂肪性肝病(NAFLD)的价值。方法回顾性分析2020年1月—2021年12月在昆明医科大学第二附属医院行睡眠呼吸监测并诊断为OSA的患者190例，依据超声检查结果分为OSA合并NAFLD组107例及对照组83例。计量资料两组间比较采用t检验或Mann-Whitney U检验；计数资料两组间比较采用χ²检验。采用二元Logistic回归分析探讨OSA患者发生NAFLD的影响因素。绘制TyG、TyG联合BMI及TyG联合WC预测OSA患者发生NAFLD的受试者工作特征曲线(ROC曲线)，计算曲线下面积(AUC)。AUC的比较采用Z检验。结果与对照组相比，OSA合并NAFLD患者的BMI、颈围、WC、AHI、ODI、ALT、GGT、TG、FPG、TyG较高，年龄、Average SpO₂、LSaO₂、HDL-C较低(P值均＜0.05)。二元Logistic分析显示TyG(OR=1.961，95%CI：1.03~3.73，P=0.040)、BMI(OR=1.203，95%CI：1.03~1.41，P=0.020)、WC(OR=1.074，95%CI：1.01~1.14，P=0.026)为OSA患者发生NAFLD的独立危险因素。TyG、TyG联合BMI及TyG联合WC预测OSA患者发生NAFLD的AUC(95%CI)分别为0.696(0.625~0.760)、0.787(0.722~0.843)和0.803(0.739~0.857)，最佳截断点分别为8.72、0.36和0.60。TyG联合BMI对OSA患者发生NAFLD的预测价值高于TyG(Z=2.542，P=0.011)，TyG联合WC的预测价值也高于TyG(Z=2.976，P=0.002 9)。结论 TyG、TyG联合BMI及TyG联合WC对OSA发生NAFLD具有良好的预测价值，以TyG联合WC的预测价值最佳，有望成为OSA患者发生NAFLD风险的预测指标。

Abstract: Objective To investigate the value of triglyceride-glucose index (TyG), TyG combined with body mass index (BMI), and TyG combined with waist circumference (WC) in predicting nonalcoholic fatty liver disease (NAFLD) in patients with obstructive sleep apnea (OSA). Methods A retrospective analysis was performed for 190 patients who underwent sleep respiratory monitoring and were diagnosed with OSA in The Second Affiliated Hospital of Kunming Medical University from January 2020 to December 2021, and according to the results of ultrasonography, they were divided into OSA+NAFLD group with 107 patients and control group with 83 patients. The t-test or the Mann Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The binary logistic regression analysis was used to explore the influencing factors for the development of NAFLD in patients with OSA. The receiver operating characteristic (ROC) curve was plotted for TyG, TyG combined with BMI, and TyG combined with WC in predicting NAFLD in the patients with OSA, and the area under the ROC curve (AUC) was calculated. The Z test was used for comparison of AUC. Results Compared with the control group, the OSA+NAFLD group had significantly higher BMI, neck circumference, WC, apnea-hypopnea index, oxygen desaturation index, alanine aminotransferase, gamma-glutamyltransferase, triglyceride, fasting plasma glucose, and TyG and significantly lower age, average SpO₂, LSaO₂, and high-density lipoprotein cholesterol (all P < 0.05). The binary logistic regression analysis showed that TyG (odds ratio [OR]=1.961, 95% confidence interval [CI]: 1.03-3.73, P=0.04), BMI (OR=1.203, 95%CI: 1.03-1.41, P=0.020), and WC (OR=1.074, 95%CI: 1.01-1.14, P=0.026) were independent risk factors for NAFLD in patients with OSA. TyG, TyG combined with BMI, and TyG combined with WC had an AUC of 0.696 (95%CI: 0.625-0.760), 0.787 (95%CI: 0.722-0.843), and 0.803 (95%CI: 0.739-0.857), respectively, in predicting NAFLD in OSA patients, with an optimal cut-off value of 8.72, 0.36, and 0.60, respectively. TyG combined with BMI had a significantly higher value than TyG in predicting NAFLD in OSA patients (Z=2.542, P=0.011), and TyG combined with WC also had a significantly higher predictive value than TyG (Z=2.976, P=0.002 9). Conclusion TyG, TyG combined with BMI, and TyG combined with WC have a good value in predicting NAFLD in OSA patients, among which TyG combined with WC has the best predictive value and is thus expected to become a predictor for the risk of NAFLD in OSA patients.
