摘要: 目的 探讨慢性阻塞性肺疾病(COPD)急性加重期(AECOPD)患者血清血清趋化因子配体18(CCL-18)的表达水平及其诊断价值。方法 纳入AECOPD患者60例(AECOPD组),根据过去1年COPD急性加重发作次数将其分为频发组27例和偶发组33例;依据COPD全球倡议(GOLD)分期将其分为Ⅰ+Ⅱ期组30例、Ⅲ期组20例、Ⅳ期组10例。选取肺功能正常的健康吸烟者20例作为对照组。比较各组受试者血清CCL-18水平。采用受试者工作特征(ROC)曲线分析血清CCL-18水平鉴别AECOPD患者和健康对照者、频发型和偶发型AECOPD患者的诊断效能。结果 AECOPD组患者血清CCL-18水平明显高于对照组(P<0.001)。频发组AECOPD血清CCL-18水平明显高于偶发组(P<0.05)。Ⅰ+Ⅱ期组、Ⅲ期组、Ⅳ期组AECOPD患者血清CCL-18水平依次升高,差异均有统计学意义(P<0.05)。ROC曲线分析结果显示,血清CCL-18诊断AECOPD的敏感度为84.1%,特异度为76.7%,ROC曲线下面积(AUC)为0.86(95%CI 0.77~0.94,P<0.001);血清CCL-18诊断频发型AECOPD的敏感度为88.0%,特异度为88.2%,AUC为0.92(95%CI 0.85~0.99,P<0.001)。结论 AECOPD患者血清CCL-18水平较健康对照者升高,且随GOLD分期增高而升高,血清CCL-18可较好地鉴别AECOPD患者与健康对照者、频发型与偶发型AECOPD患者。

Abstract: Objective To explore the expression level of serum chemokine ligand 18(CCL-18) in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD) and its diagnostic value.Methods A total of 60 patients with AECOPD(AECOPD group) were concluded.According to the frequency of acute exacerbation of COPD in the past year,they were divided into frequent group(27 cases) and accidental group(33 cases).According to the stage of global initiative for COPD(GOLD),they were divided into stage Ⅰ+Ⅱ group(30 cases),stage Ⅲ group(20 cases) and stage Ⅳ group(10 cases).The 20 healthy smokers with normal lung function were selected as the control group.Levels of serum CCL-18 in subjects of each group were detected by enzyme linked immunosorbent assay(ELISA) and compared.The diagnostic efficacy of serum CCL-18 in distinguishing AECOPD patients from healthy controls,frequent AECOPD patients from occasional AECOPD patients was analyzed by receiver operating characteristic(ROC) curve.Results Level of serum CCL-18 in patiens of AECOPD group was higher than that in control group(P<0.001).Level of serum CCL-18 in AECOPD patietns of frequent group was higher than that in incidental group(P<0.05).Levels of serum CCL-18 in stage Ⅰ+Ⅱ group,stage Ⅲ group and stage Ⅳ group increased gradually,and the differences were significant(P<0.05).Results of ROC curve analysis showed that sensitivity,specificity and area under ROCcurve(AUC) of serum CCL-18 in diagnosing AECOPD were 84.1%,76.7% and 0.86(95% CI 0.77~0.94,P<0.001) respectively.Sensitivity,specificity and AUC of serum CCL-18 in diagnosing frequent AECOPD were 88.0%,88.2% and 0.92(95%CI 0.85~0.99,P<0.001).Conclusion The level of serum CCL-18 in patients with AECOPD is higher than that in healthy controls,and it increases along with GOLD stage increasing.Serum CCL-18 can distinguish AECOPD patients from healthy controls,frequent AECOPD patients and incidental AECOPD patients.
