The levels of serum IMA,Gremlin-1 and meteorin-like protein in patients with different clinical grades of diabetic foot and their predictive value for poor prognosis
摘要
Abstract
Objective To investigate the levels of serum ischemia-modified albumin(IMA),Gremlin-1 and meteorin-like protein in patients with different clinical grades of diabetic foot(DF)and their predictive value for poor prognosis.Methods A total of 198 patients with DF admitted to Qinhuangdao Hospital of Peking U-niversity Third Hospital from May 2022 to October 2024 were selected as the DF group,and 152 patients with simple type 2 diabetes mellitus(T2DM)without diabetes-related complications who visited Qinhuangdao Hospital of Peking University Third Hospital during the same period were selected as the control group.The patients were followed up for 6 months,and the 198 DF patients were divided into the poor prognosis group and the good prognosis group according to the prognosis.The levels of serum IMA,Gremlin-1 and meteorin-like protein in the patients were detected by enzyme-linked immunosorbent assay.Multivariate Logistic re-gression analysis was used to analyze the influencing factors of poor prognosis in DF patients.The receiver op-erating characteristic(ROC)curve was drawn to analyze the predictive value of serum IMA,Gremlin-1 and meteorin-like protein for poor prognosis in DF patients.Results The levels of glycated hemoglobin and serum IMA,Gremlin-1 in the DF group were higher than those in the control group,while the level of serum meteor-in-like protein was lower than that in the control group,and the differences were statistically significant(P＜0.05).The levels of serum IMA and Gremlin-1 in DF patients with Wagner grade 4 were higher than those in patients with Wagner grades 1,2 and 3,and the levels of serum IMA and Gremlin-1 in DF patients with Wag-ner grade 3 were higher than those in patients with Wagner grades 1 and 2,and the levels of serum IMA and Gremlin-1 in DF patients with Wagner grade 2 were higher than those in patients with Wagner grade 1,all with statistically significant differences(P＜0.05).The level of serum meteorin-like protein in DF patients with Wagner grade 4 was lower than that in patients with Wagner grades 1,2 and 3,and the level of serum meteorin-like protein in DF patients with Wagner grade 3 was lower than that in patients with Wagner grades 1 and 2,and the level of serum meteorin-like protein in DF patients with Wagner grade 2 was lower than that in patients with Wagner grade 1,all with statistically significant differences(P＜0.05).The levels of serum IMA and Gremlin-1 in the poor prognosis group were higher than those in the good prognosis group,and the level of serum meteorin-like protein was lower than that in the good prognosis group,all with statistically sig-nificant differences(P＜0.05).The proportions of patients with Wagner grades 3-4,vascular lesions,periph-eral neuropathy and the level of procalcitonin in the poor prognosis group were higher than those in the good prognosis group,all with statistically significant differences(P＜0.05).The results of multivariate Logistic regression analysis showed that elevated procalcitonin,IMA,Gremlin-1 levels and Wagner grade 3-4 were risk factors for poor prognosis in DF patients(P＜0.05),and elevated meteorin-like protein level was a pro-tective factor for poor prognosis in DF patients(P＜0.05).The result of ROC curve analysis showed that the area under the curve(AUC)for the combined prediction of poor prognosis in DF patients by serum IMA,Gremlin-1 and meteorin-like protein was 0.925,which was greater than the AUC of each of these three indi-cators when used alone(P＜0.05).Conclusion The levels of serum IMA,Gremlin-1 and meteorin-like pro-tein are closely related to the disease grade of DF patients,and the combined detection of these three indicators has a high predictive value for poor prognosis in DF patients.关键词
