MLPR、NLR、RDW对老年AECOPD患者合并肺栓塞的评估价值

目的探讨单核细胞/大血小板比值(MLPR)、中性粒细胞/淋巴细胞比值(NLR)、红细胞分布宽度(RDW)对老年慢性阻塞性肺疾病急性加重(AECOPD)患者合并慢性阻塞性肺病急性加重的评估价值。方法选取2020年1月至2022年12月邯郸市第一医院收治的118例老年AECOPD合并肺栓塞患者作为观察组,并根据FEV1占预计值的百分比(FEV1%pred)水平分为轻度、中度、重度、极重度,选取同期80例老年AECOPD未合并肺栓塞患者为对照组。对比两组一般临床资料,探讨影响老年AECOPD患者合并肺栓塞的危险因素;评估MLPR、NLR、RDW水平对老年AECOPD患者合并肺栓塞的诊断效能及与疾病严重程度的相关性。结果观察组病程、MLPR、NLR、RDW、血小板/淋巴细胞比值(PLR)、纤维蛋白原(FIB)、D-二聚体均高于对照组,差异有统计学意义(t=7.409、17.995、10.733、8.724、13.983、7.829、10.596,P<0.05);Logistic分析显示,病程、MLPR、NLR、RDW、PLR、FIB、D-二聚体均为老年AECOPD患者合并肺栓塞的独立危险因素(P<0.05);MLPR、NLR、RDW三者单独及联合检测诊断AUC分别为0.866、0.835、0.795、0.937,联合检测优于单一检测(P<0.05);老年AECOPD患者合并肺栓塞MLPR、NLR、RDW水平为极重度>重度>中度>轻度,差异有统计学意义(F=126.998、37.074、34.927,P<0.05);Spearman分析显示,MLPR、NLR、RDW与疾病严重程度呈正相关(r=0.865、0.775、0.661,P<0.05)。结论老年AECOPD患者合并肺栓塞时MLPR、NLR、RDW水平升高并与疾病严重程度呈正相关,三者联合检测对老年AECOPD患者合并肺栓塞具有良好的诊断效能。

The Value of MLPR,NLR,and RDW in the Assessment of Combined Pulmonary Embolism in Elderly Patients with AECOPD

Objective:To investigate the diagnostic value of the monocyte-to-large-platelet ratio(MLPR),neutrophil-to-lymphocyte ratio(NLR),and red blood cell distribution width(RDW)for pulmonary embolism(PE)in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods:A total of 60 elderly AECOPD patients were enrolled and divided into embolus group(12 cases)and thrombus group(48 cases)according to whether they were combined with pulmonary embolism and the MLPR,NLR,and RDW values of the two groups were determined respectively.Results:The patients in the two groups had different degrees of vascular structural and functional abnormalities,and the MLPR,NLR,and RDW in the embolus group were significantly higher than those in the thrombus group(P<0.05);while the differences in NLR and RDW between the two groups were not significant.Conclusion:MLPR,NLR,and RDW can provide an objective basis for assessing PE in elderly AECOPD patients.
