糖皮质激素对痰嗜酸性粒细胞阳性COPD患者的疗效评价

目的论证痰检嗜酸粒细胞阳性的COPD患者是否预示吸入糖皮质激素的临床和功能反应较好。方法60例痰检嗜酸粒细胞阳性的AECOPD患者随机分为治疗组(28例)及对照组(32例),治疗组应用糖皮质激素及常规治疗,对照组应用糖皮质激素(静脉予甲基强的松龙40 mg/d×0～3天后即停用)及常规治疗,共6个月。常规治疗包括:控制性氧疗,抗感染,化痰,止咳,应用支气管舒张剂等。治疗前及治疗后10天、30天测FEV1、FEV1占预计值百分比、FEV1/FVC,统计6个月内首次COPD严重急性发作时间和COPD急性加重发生率。结果治疗组FEV1、FEV1占预计值百分比、FEV1/FVC均有明显提高,两组之间差异有显著性(P0.05),治疗组首次COPD严重急性发作时间(98.21±36.35天)较对照组(63.54±25.62)明显延长(P0.05),治疗组的COPD急性加重发生率34.5%明显少于对照组48.6%。结论痰检嗜酸粒细胞阳性患者预示吸入糖皮质激素的临床和功能反应较好,痰检嗜酸粒细胞阳性是临床COPD患者应用糖皮质激素的指标,值得临床推广应用。

Clinical trial design of using sputum eosinophils in assessing the effectiveness of glucocorticoid therpy of chronic obstructive pulmonary disease

Objective To investigate positive sputum eosinophils of patients with COPD to test whether it has better clinical and functional response of inhaled glucocorticoid.Methods 60 COPD patients of positive sputum eosinophils were randomly divided into treatment group(28 cases)and control group(32 cases).The treatment group was given sequential glucocorticoid and regular treatment.The control group was given regular treatment for six months.The data was analyzed on the first onset time and the incidence of acute ...
