Abstract:Objective To explore the diagnostic value of adiponectin (APN), direct bilirubin (DB), triglyceride (TG) and their combination for macro-vascular complications (MVC) in patients with type 2 diabetes (T2DM).Methods One hundred and twenty patients with T2DM were divided into T2DM group (n = 62) and T2DM + MVC group (n = 58) according to whether they were complicated with macrovascular diseases. Univariate and multivariate logistic regression were used to analyze the risk factors of T2DM patients with MVC. The diagnostic efficacy of APN, DB, TG, and their combination on T2DM patients with MVC was evaluated by plotting ROC curve.Results The results of stepwise logistic regression analysis showed that HbA1 level [O^R = 24.096 (95% CI: 6.419, 90.453) ], LDL-C level [O^R = 13.118 (95% CI: 2.202, 78.134) ] and TG level [O^R = 7.019 (95% CI: 2.414, 20.407) ] were the risk factors of T2DM patients with MVC (P <0 .05); HDL-C level [O^R = 0.000 (95% CI: 0.000, 0.011) ], APN level [O^R = 0.504 ( 95% CI: 0.313, 0.809) ], and DB level [O^R = 0.694 (95% CI: 0.581, 0.829) ] were protective factors for T2DM patients with MVC (P < 0.05). ROC analysis showed that when APN ≤ 5.870 nmol/mL, the area under the curve (AUC) of T2DM patients with MVC was 0.718, the sensitivity was 70.7% (95% CI: 0.571, 0.815), and the specificity was 61.3% (95% CI: 0.480, 0.713); When DB ≤ 14.205 mol/L, AUC is 0.772, sensitivity is 74.1% (95% CI: 0.607, 0.844), specificity is 71.0% (95CI: 0.579, 0.814); When TG ≥ 1.955 mol/L, AUC is 0.735, sensitivity is 72.4% (95% CI: 0.589, 0.830), specificity is 69.4% (95% CI: 0.562, 0.801); The AUC of the combined diagnosis was 0.881, the sensitivity was 84.5% (95% CI: 0.721, 0.922), and the specificity was 77.4% (95% CI: 0.647, 0.867).Conclusion APN, DB, and TG can be used for the auxiliary diagnosis of T2DM patients with MVC, and the combination of the three can further improve the diagnostic efficiency.
