Correlation between serum decoy receptor 3 and airflow restriction,quality of life,and exacerbations within 1 year in patients with moderate to severe stable COPD
目的 探讨中重度稳定期慢性阻塞性肺病(COPD)患者的血清诱饵受体 3(DcR3)水平,并研究DcR3 与气流受限、生活质量和 1 年内急性发作的相关性.方法 选取2021-08 至2022-08 空军第986 医院诊治的81 例中重度稳定期COPD患者作为研究对象,采用酶联免疫吸附法测量血清DcR3 水平,并使用Spearman相关性分析血清DcR3 与气流限制和生活质量的相关性,二元logistic回归分析影响 1 年内急性发作的临床因素,受试者工作特征(ROC)曲线分析血清DcR3 预测 1 年内急性发作的临床价值.结果 与血清DcR3≥2.45 ng/ml(中位值)组比较,血清DcR3<2.45 ng/ml组嗜碱性粒细胞计数显著升高(P<0.05),1 年内急性发作次数和住院次数显著减少(P<0.05).血清 DcR3 与第一秒用力呼气容积(FEV1)(r=-0.389)、FEV1/用力肺活量(FVC)(r=-0.610)、一氧化碳弥散量(r=-0.611)、吸气量(IC)/肺总量比值(TLC)(r=-0.862)呈负相关性,P均<0.05.血清DcR3 与COPD评估试验(CAT)(r=0.638)、视觉模拟量表(VAS)-咳嗽(r=0.282)、VAS-咳痰(r=0.269)、VAS-脓痰(r=0.237)评分呈正相关性,P<0.05.白细胞介素(IL)-6 与被检者 75%的最大呼气流速(r=-0.481)呈负相关,C反应蛋白(CRP)与CAT评分(r=0.521)呈正相关(P<0.05).经二元logistic回归,血清DcR3 与COPD1 年内急性发作独立相关(P<0.05).血清DcR3 预测COPD患者 1 年内急性发作的曲线下面积为[0.788(95%CI:0.688～0.888)],当血清DcR3≥2.435 ng/ml时,灵敏度(0.689)和特异度(0.833)最高.结论 COPD患者中血清DcR3 与气流受限、生活质量、疾病严重程度,以及 1 年内急性发作有关,血清DcR3 水平有作为COPD患者发病机制标志物的潜力.
Objective To investigate the serum Decoy Receptor 3(DcR3)level in patients with chronic obstructive pulmona-ry disease(COPD)and to investigate the correlation of DcR3 with airflow restriction,quality of life and acute exacerbations within 1 year.Methods From August 2021 to August 2022,81 patients with moderate to severe COPD were included as study subjects.Serum DcR3 levels were measured by enzyme-linked immunosorbent assay,and the correlation of serum DcR3 with airflow restriction and quality of life was analyzed by Spearman correlation analysis.The clinical factors influencing acute exacerbations within 1 year were an-alyzed by binary Logistic regression,and the clinical value of serum DcR3 in predicting acute exacerbations within 1 year was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the serum DcR3≥2.45 ng/ml(median)group,the baso-phil count in the serum DcR3<2.45 ng/ml group significantly increased(P<0.05),and the number of acute exacerbation and hospi-talizations within 1 year significantly decreased(P<0.05).Serum DcR3 was negatively correlated with forced expiratory volume in the first second(FEV1)(r=-0.389),FEV1/forced vital capacity(FVC)(r=-0.610),diffusing capacity of the lungs for carbon mon-oxide(r=-0.611),and inspiratory volume(IC)/total lung ratio(TLC)(r=-0.862),all P<0.05.There was a positive correlation between serum DcR3 and COPD assessment test(CAT)(r=0.638),visual analogue scale(VAS)-cough(r=0.282),VAS-sputum(r=0.269)and VAS-purulent sputum(r=0.237)scores,all P<0.05.Interleukin(IL)-6 was negatively correlated with 75%of the maximum expiratory flow rate(r=-0.481),and C-reactive protein(CRP)was positively correlated with CAT score(r=0.521),both P<0.05.By binary logistic regression,serum DcR3 was independently correlated with acute exacerbations of COPD within one year(P<0.05).The area under the curve of serum DcR3 in predicting acute exacerbations in COPD patients within 1 year was[0.788(95%CI:0.688～0.888)],and the sensitivity(0.689)and specificity(0.833)were the highest when serum DcR3≥2.435 ng/ml.Conclusions Serum DcR3 is associated with airflow restriction,quality of life,disease severity and acute onset within 1 year in COPD patients,and serum DcR3 level has potential as a marker of patho-genesis of COPD patients.
