摘要:

目的 分析老年糖尿病足溃疡(DFU)患者血小板(PLT)和凝血功能指标的变化及其临床意义。方法 选取2022年1月—2023年12月无锡市第九人民医院住院的≥60岁DFU患者79例(DFU组)和未合并DFU的2型糖尿病(T2DM)患者86例(T2DM组)。测定空腹血糖、糖化血红蛋白、红细胞沉降率、C肽、铁蛋白、总蛋白、白蛋白、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、三酰甘油、总胆固醇、肌酐、尿素氮、PLT计数和活化部分凝血活酶时间(APTT)、凝血酶原时间(PT)、凝血酶时间(TT)、纤维蛋白原(Fib)、抗凝血酶Ⅲ(AT-Ⅲ)、纤维蛋白(原)降解产物(FDP)、D-二聚体(DD)。收集患者临床资料。比较DFU组和T2DM组临床资料和相关指标差异;采用Logistic回归分析评估DFU的影响因素。结果 DFU组肌酐、尿素氮,PLT、PT、Fib、FDP、DD水平高于T2DM组(P<0.05),白蛋白、HDL-C、总胆固醇水平显著低于T2DM组(P<0.05)。PLT计数、PT与HDL-C呈正相关(P<0.05),AT-Ⅲ与白蛋白、肌酐、尿素氮呈正相关(P<0.05),Fib与白蛋白、HDL-C、总胆固醇呈负相关(P<0.05),DD与白蛋白、HDL-C呈负相关(P<0.05)。Fib和FDP是DFU的独立危险因素(P<0.05),AT-Ⅲ是DFU的保护因素(P<0.05)。结论 老年DFU患者存在高凝状态。DFU发生与PLT、凝血功能关系密切,监测PLT和凝血功能有助于早期发现T2DM并发症。

Abstract:

Objective To analyze the changes and clinical roles of platelet (PLT) and coagulation function indicators in elderly patients with diabetic foot ulcers (DFU). Methods A total of 79 patients aged ≥60 years with type 2 diabetes mellitus (T2DM) combined with DFU (DFU group) and 86 patients with T2DM without DFU (T2DM group) at Wuxi Ninth People's Hospital Affiliated to Soochow University from January 2022 to December 2023 were enrolled. Fasting blood glucose(FBG),glycated hemoglobin A1c(HbA1c),erythrocyte sedimentation rate(ESR),C-peptide,ferritin,total protein(TP),albumin(Alb),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),triglyceride(TG),total cholesterol(TC),creatinine(Cr),urea nitrogen,platelet (PLT) count and activated partial thromboplastin time(APTT),prothrombin time (PT),thrombin time(TT),fibrinogen(Fib),antithrombin-Ⅲ(AT-Ⅲ),fibrin(fibrinogen) degradation product (FDP) and D-dimer(DD)were determined. The clinical data of patients were collected. The differences in clinical indicators between DFU group and T2DM group were compared. Logistic regression analysis was used to evaluate the influencing factors of DFU. Results Cr,urea nitrogen,PLT count,PT,Fib,FDP and DD in DFU group were higher than those in T2DM group (P<0.05),and Alb,HDL-C and TC were lower than those in T2DM group (P<0.05). PLT count,PT and HDL-C were positively correlated (P<0.05),AT-Ⅲ was positively correlated with Alb,Cr and urea nitrogen (P<0.05),Fib was negatively correlated with Alb,HDL-C and TC (P<0.05),and DD was negatively correlated with Alb and HDL-C (P<0.05). Fib and FDP were independent risk factors for DFU (P<0.05),and AT-III was a protective factor for DFU (P<0.05). Conclusions Elderly patients with T2DM combined with DFU have a hypercoagulable state. The occurrence of DFU is related to PLT count and coagulation function. Monitoring PLT count and coagulation function is helpful for the early determination of complications of T2DM.
