Abstract:
Objective To explore the relationship between serum growth differentiation factor-15(GDF-15),chemerin,pentraxin 3(PTX3)levels and obesity,insulin resistance and inflammatory factors in patients with type 2 diabetes mellitus(T2DM),and to construct and evaluate the predictive efficacy.Methods A total of 231 T2DM patients admitted to the hospital from February 2020 to September 2022 were selected as T2DM group.Another 100 healthy subjects who came to the hospital for physical examination during the same period were selected as the control group.Serum GDF-15,chemerin and PTX3 levels of the two groups were detected and compared by enzyme-linked immunosorbent assay(ELISA).Clinical data of the two groups were collected and compared.Pearson correlation analysis and multiple linear regression were used to analyze the relationship between serum GDF-15,chemerin,PTX3 levels and obesity,insulin resistance and inflammation.Multivariate Logistic regression was used to evaluate the independent risk factors for T2DM development,and the com-bined prediction model of serum GDF-15,chemerin and PTX3 was constructed,and receiver operating charac-teristic(ROC)curve was plotted to evaluate its predictive efficacy for T2DM development.Results Compared with the control group,body mass index(BMI),waist-to-hip ratio(WHR),systolic blood pressure,total cho-lesterol,triglyceride,fasting blood glucose,fasting insulin(FINS),homeostasis model assessment of insulin re-sistance(HOMA-1R),interleukin(IL)-1β,IL-6,GDF-15,chemerin and PTX3 were all increased in T2DM group,and the differences were statistically significant(P＜0.05).Pearson correlation analysis showed that se-rum GDF-15,chemerin and PTX3 levels were positively correlated with BMI,WHR,FINS,HOMA-IR,IL-1βand IL-6 in T2DM group(P＜0.05).Multiple linear regression analysis showed that BMI,FINS,HOMA-IR,IL-1β and IL-6 were positively correlated with serum GDF-15,chemerin and PTX3 levels(P＜0.05).Multiva-riate Logistic regression analysis showed that the increase of serum GDF-15,chemerin and PTX3 levels was an independent risk factor for T2DM development(P＜0.05).ROC curve analysis results showed that the com-bined prediction model of serum GDF-15,chemerin and PTX3 had better prediction efficiency,and its area un-der the curve,sensitivity,specificity and accuracy were higher than those applied alone.Conclusion The levels of GDF-15,chemerin and PTX3 in serum of T2DM patients are elevated,and their levels increase with the ex-acerbation of obesity,insulin resistance and inflammatory response in T2DM patients.The combined predic-tion model constructed in this study has good predictive efficacy and has high predictive value for the occur-rence of T2DM.
