摘要
目的:检测支气管哮喘(简称哮喘)急性发作期患者治疗前后血清白细胞介素20(IL-20)水平的变化,探讨IL-20在哮喘发病机制中的作用和临床意义。方法:选择2013年5-10月广西医科大学第一医院呼吸内科门诊收治的轻至中度急性发作哮喘患者45例作为哮喘组,体检中心的32例健康体检者作为对照组。哮喘组患者均接受沙美特罗替卡松50/250μg/μg(1吸,2次/d)、万托林(必要时)治疗,中度哮喘组加用茶碱缓释片,总疗程1周。分别检测哮喘组治疗前后及对照组血清IL-20的水平。同时检测免疫球蛋白E(IgE)、嗜酸粒细胞(EOS)数量、巨噬细胞趋化蛋白ECP及肺功能[FEV1占预计值百分比(FEV1%)]等,比较哮喘组治疗前后IL-20水平的变化及其与对照组之间的差异,分析其与IgE、EOS、ECP和FEV1%等指标的相关性。结果:轻度和中度哮喘组治疗前血清IL-20水平[(23.43±13.60)pg/L和(33.78±22.69)pg/L]均高于对照组[(13.58±6.17)pg/L],差异有统计学意义,中度组高于轻度组。轻度和中度哮喘组治疗后血清IL-20分别为(15.73±8.27)pg/L和(19.64±11.69)pg/L均低于治疗前,差异有统计学意义。Pearson相关分析显示,IL-20与IgE,EOS和ECP呈正相关,而与FEVl%呈负相关。结论:IL-20可能参与了支气管哮喘发病过程。
Objective To detect the pre- and post-treatment levels of serum interleukin （IL-20） in asthmatic patients during the acute exacerbation period and to investigate the role of IL-20 in the pathogenesis of bronchial asthma and relative clinical significance. Methods Forty-five cases of mild to moderate asthma outpatients in the First Affiliated Hospital of Guangxi Medical University from May 2013 to October 2013 were chosen as the asthma group and 32 healthy people who underwent routine physical examination as the control group. All the patients were treated with inhalation salmeterol and fluticasone 50/250 μg/μg （sucking twice a day） together with ventolin if necessary , and even with theophylline sustained-release tablets as the additional treatment in moderate asthma group for 1 week. The serum levels of IL-20 as well as immunoglobulin E （IgE） were detected by ELISA in the asthma group before and after treatment as well as in the control group. Other data including ECP , the number of eosinophil ceils （EOS） and the pulmonary function （FEV1%） were detected as well. The differences of IL-20 levels between the asthma group before and after treatment and the control group were analyzed and the correlation between IL-20 and Ig E, EOS, ECP and FEV1% were analyzed. Results Compared with the healthy control group [（13.58 ± 6.17）pg/L], the levels of IL-20 in the mild and moderate asthma pretreatment group were significantly increased [（23.43 ± 13.60）pg/L and （33.78 ± 22.69）pg/L]. Compared with the mild asthma group, the levels of IL-20 in the moderate asthma pretreatment group were significantly higher. After treatment , the levels of IL-20 [（15.73 ± 8.27）pg/L and （19.64 ± 11.69）pg/L] were decreased respectively in the asthmatic patients. The Pearson correlative analysis showed that there were positive correlations between the levels of 1L-20 and IgE , EOS and ECP respectively and there were negative correlations between IL-20 levels and FEV1%. Conclusion IL-20 may be involve
