哮喘患者外周血血小板-淋巴细胞比值和中性粒细胞-淋巴细胞比值的临床意义

目的:探讨外周血中性粒细胞-淋巴细胞比值(neutrophil-lymphocyte ratio, NLR)和血小板-淋巴细胞比值(platelet-lymphocyte ratio, PLR)在支气管哮喘急性发作期患者中的变化及临床意义。方法选取2013年1月~2016年5月期间确诊的支气管哮喘急性发作期患者262例为病例组及130例健康体检者为正常对照组。根据其急性发作期病情严重程度,将哮喘患者分为危重组87例、非危重组175例。记录病例组和健康对照组性别、年龄等临床资料和血常规结果,并计算NLR和PLR。比较3组间中性粒细胞绝对值、淋巴细胞绝对值、血小板计数、NLR、PLR的差异,以RO...

Summary:目的:探讨外周血中性粒细胞-淋巴细胞比值(neutrophil-lymphocyte ratio, NLR)和血小板-淋巴细胞比值(platelet-lymphocyte ratio, PLR)在支气管哮喘急性发作期患者中的变化及临床意义。方法选取2013年1月~2016年5月期间确诊的支气管哮喘急性发作期患者262例为病例组及130例健康体检者为正常对照组。根据其急性发作期病情严重程度,将哮喘患者分为危重组87例、非危重组175例。记录病例组和健康对照组性别、年龄等临床资料和血常规结果,并计算NLR和PLR。比较3组间中性粒细胞绝对值、淋巴细胞绝对值、血小板计数、NLR、PLR的差异,以ROC曲线评价各指标对哮喘的诊断价值。结果各组间中性粒细胞绝对值、淋巴细胞绝对值、NLR、PLR差异具有统计学意义(P〈0.0001),各组血小板计数差异无统计学意义(P=0.971)。哮喘危重组淋巴细胞绝对值低于哮喘非危重组、健康对照组(P〈0.0001),而中性粒细胞绝对值、NLR、PLR显著高于哮喘危重组、健康对照组(P〈0.0001)。哮喘非危重组中性粒细胞绝对值、淋巴细胞绝对值、NLR、PLR与健康对照组相比差异无统计学意义(P〉0.05)。中性粒细胞绝对值、淋巴细胞绝对值、NLR、PLR对支气管哮喘急性发作期危重患者诊断的曲线下面积分别为0.802、0.784、0.873、0.795(均P〈0.01)。NLR诊断支气管哮喘急性发作期危重患者的最佳临界值为2.58,敏感度为82.8%,特异度为81.1%。结论支气管哮喘患者外周血NLR、PLR均升高,对支气管哮喘的诊断和病情监测有一定临床指导意义。

Objective To investigate the changes of peripheral blood neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in patients in acute stage of bronchial asthma and their clinical significance. Methods A total of 262 patients with acute asthma, including 97 critical and 175 non-critical patients, were recruited from our hospital between January, 2013 and May, 2016, with 130 healthy individuals as the control group. The absolute neutrophil count, absolute lymphocyte count, platelet, NLR and PLR were compared among different groups, and their diagnostic values were evaluated using the area under the receiver-operating characteristic (ROC) curve. Results The absolute neutrophil count, absolute lymphocyte count, PLR and NLR (P〈0.0001),
