摘要
目的:观察缓解期哮喘和稳定期中、重度慢性阻塞性肺疾病(COPD)患者吸入高渗盐水诱导痰的安全性和有效性。方法:吸入沙丁胺醇200μg后10m in吸入3%的高渗盐水诱导痰。观察16例哮喘患者、14例COPD患者和11例健康对照者诱导痰前、后肺功能、心率(HR)、呼吸频率(RR)、血氧饱和度(SaO2)和不良反应,做诱导痰炎性细胞分类计数。夹心法酶联免疫吸附实验(ELISA)测定诱导痰上清液中白细胞介素-5(IL-5)的含量。结果:哮喘和COPD患者诱导痰前后肺功能、HR、RR和SaO2均无显著变化(P>0.05)。哮喘组患者诱导痰中嗜酸性粒细胞数(16.3±7.2)%显著高于对照组(0.7±0.6)%和COPD组(6.5±5.4)%(P<0.05),而COPD组患者诱导痰中中性粒细胞数(59.4±10.6)%显著高于对照组(25.1±6.1)%和哮喘组(28.7±7.3)%(P<0.05)。哮喘组诱导痰中IL-5水平(53.3±24.2)ng/L显著高于对照组(20.2±4.1)ng/L和COPD组(29.8±4.7)ng/L(P<0.05)。COPD组患者中性粒细胞数的百分比与基础第1秒用力肺活量(FEV1)间呈负相关(r=-0.58,P<0.05)。哮喘组和COPD组不良反应发生率分别为31.25%和42.86%,但轻微且均能耐受。结论:缓解期哮喘和稳定期中、重度COPD患者吸入高渗盐水进行痰的诱导是安全的。诱导痰的分析能反映哮喘和COPD的气道炎症特征。
Objective : To investigate the safety and effectivity of hypertonic saline on sputum induction in patients with asthma in remission stages and moderate-severe stable chronic obstructive pulmonary disease(COPD). Methods:All subjects inhaled 3% hypertonic saline for sputum induction at 10 minutes after inhalation of 200μg salbutamol. Changes of lung function , heart rate ( HR), respiratory rate ( RR), saturation of blood oxygen ( SaO2 ), and the side-effects after sputum induction were observed in 16 asthmatics ,in 14 COPD patients and in 10 healthy volunteers. The differential counts of sputum inflammatory cells were studied. The interleukin-5 (IL-5) in sputum supernatants was detected using enzyme-linked immunosorbent assay (ELISA). Results : No significant differences in lung function, HR, RR and SaO2 after sputum induction were found in patients with asthma and COPD ( P 〉 0.05 ). The percentage of eosinophils in induced sputum in asthmatics ( 16.3 ± 7.2) % was higher than those in healthy volunteers (0.7 ± 0.6 ) % and in COPD (6.5 ± 5.4) % ( P 〈 0.05 ). The percentage of neutrophil in induced sputum in COPD (59.4 ± 10.6)% was higher than those in healthy volunteers (25.1 ± 6.1 ) % and in asthmatics (28.7 ± 7.3) % (P 〈 0.05 ). The level of IL-5 in induced sputum in asthmatics (53.3 ± 24.2 ) ng/L was higher than those in healthy volunteers ( 20.2 ± 4. 1 ) ng/L and in COPD (29.8 ±4.7 )ng/L(P 〈0.05). the percentage of neutrophil in induced sputum in COPD correlated inversely with baseline forced expiratory volume in one second (FEV1) (r = -0.58, P 〈 0.05). The side-effect rates were 31. 25% and 42. 86% respectively in patients with asthma and COPD,but the degree was mild and well tolerated. Conclusion:Sputum induction after inhalation of salbutamol are safe in patients with asthma in remission stages and moderate -severe stable COPD. The analysis of induced sputum can reflect the characteristic of airway
