摘要:

目的 分析不同水平血嗜酸性粒细胞的慢性阻塞性肺疾病(chronic obstructive pulmonary dis⁃ ease,COPD)急性加重期患者临床表现、激素治疗反应性并随访其预后。方法 收集 2020 1-12 月在 天津医科大学总医院呼吸与危重症学科住院的 124 COPD 患者,以入院 24 h 内血嗜酸粒细胞绝对值 计数为基线水平将患者分为 3 组,组Ⅰ为低 EOS 组(EOS# < 100 细胞/μL)(52 例),组Ⅱ为中 EOS 100 细胞/μL ≤EOS# ≤ 300 细胞/μL)(51 例),组Ⅲ为高 EOS 组(EOS# > 300 细胞/μL)(21 例),并分析 相关数据。结果 低水平血嗜酸性粒细胞(EOS# < 100/μL)患者病情更危重;中、高水平血嗜酸性粒细 胞(EOS# ≥ 100/μL)患者对糖皮质激素应答好,长期ICS治疗可减少EOS#> 300细胞/μL 患者再发重度急性 加重风险。结论 血嗜酸性粒细胞对评价慢阻肺急性加重期患者的病情严重程度、ICS 获益及临床预 后有重要的参考价值。

Abstract:

Objective To analyze the clinical characteristics,laboratory examination indicators,glucocor⁃ ticoid therapy responsiveness of hospitalized patients with AECOPD with different blood eosinophil levels and to follow up for the prognosis. Methods A total of 124 COPD patients hospitalized in the Department of Respiratory and Critical Care Medicine,General Hospital of Tianjin Medical University from January 1 to December 31,2020 were concluded. The patients were divided into 3 groups according to the absolute value of blood eosinophil count within 24 hours of admission as the baseline level;the relevant data were analyzed and the curve was drawn. Results Blood eosinophil levels could assess the severity of disease progression in patients with AECOPD. Patients with EOS less than 100 cells/μL were more critically ill,but those with EOS greater than or equal to 100 cells/μL responded well to glucocorticoids,and long ⁃term ICS treatment can reduce the risk of recurrent severe exacerba⁃ tions in patients with EOS greater than 300 cells/μL. Conclusion The level of blood eosinophils helps to assess the degree of deterioration,benefit from ICS,and prognosis in AECOPD patients.
