[摘要] 目的 觀察肺泡灌洗治療支氣管感染的臨床療效,并探討IL-17、IL-8、IL-4等炎癥因子在支氣管哮喘發(fā)病中的作用。方法 隨機(jī)選擇該院2013年1月—2014年1月收治的30例支氣管哮喘急性發(fā)作期患者納入觀察組,另選30例性別,年齡,病程資料相同的患者,進(jìn)行常規(guī)治療納入對照組,觀察組患者采用纖維支氣管鏡下肺泡灌洗術(shù)治療,觀察治療后的PaO2、SaO2和PaCO2改善情況及臨床療效;同時采集所有研究對象的支氣管肺泡灌洗液(BALF),采用多抗體夾心酶聯(lián)免疫吸附方法檢測2組BALF中IL-17、IL-8、IL-4的含量。 結(jié)果 經(jīng)支氣管肺泡灌洗治療后,觀察組總有效率為96.6%,PaO2和SaO2均較治療前升高,差異有統(tǒng)計學(xué)意義(P<0.05),PaCO2較治療前降低,差異有統(tǒng)計學(xué)意義(P<0.05);觀察組BALF上清液中IL- 17、IL-8的水平較正常對照組升高,差異有統(tǒng)計學(xué)意義(P<0.05)。結(jié)論 支氣管肺泡灌洗可顯著改善支氣管哮喘患者氣道功能,臨床療效顯著。 IL-17、IL-8 可能介導(dǎo)了支氣管哮喘患者急性發(fā)作期的發(fā)作。

[Abstract] Objective To observe the clinical efficacy of bronchoalveolar lavage in the treatment of bronchial asthma and investigate the role of inflammatory cytokines, such as IL-17, IL-8, IL-4 in the pathogenesis of bronchial asthma. Methods 30 patients with acute exacerbation of bronchial asthma admitted in our hospital from January 2013 to January 2014 were enrolled into observation group, and other 30 patients with the same gender, age, and data of course of disease were enrolled into the control group. Patients in the observation group were treated by bronchoalveolar lavage with fiberbronchoscope, and the control group was treated by the conventional treatment. The improvement of PaO2, SaO2 and PaCO2 and clinical efficacy were observed after treatment. Levels of IL-17, IL-8, IL-4 in bronchoalveolar lavage fluid (BALF) of all subjects were collected and detected with multi- antibody sandwich ELISA. Results After the bronchoalveolar lavage treatment, in the observation group, the total effective rate was 96.6%, PaO2 and SaO2 increased significantly(P<0.05) and PaCO2 decreased significantly compared with pre-treatment(P<0.05); the levels of IL-17 and IL-8 in BALF supernatant in the observation group were significantly higher than those in the control group(P<0.05). Conclusion Bronchoalveolar lavage can significantly improve the airway function in patients with bronchial asthma with significant clinical effect. IL-17, IL-8 may mediate the acute exacerbation of bronchial asthma attack.

支氣管哮喘為臨床常見的嗜酸性粒細(xì)胞浸潤炎癥性呼吸道疾病,臨床表現(xiàn)為氣道上皮損傷、纖維化以及基底膜增厚等氣道重塑現(xiàn)象[1]。其發(fā)病機(jī)制目前尚不明確,多與氣道慢性炎癥有關(guān),常由多種炎癥細(xì)胞、炎癥介質(zhì)及細(xì)胞因子介導(dǎo)[2],因此患者機(jī)體內(nèi)炎癥因子的水平對疾病診斷、病情判斷及疾病轉(zhuǎn)歸均有重要意義。該研究通過檢測該院2013年1月—2014年1月收治的30例哮喘急性發(fā)作患者支氣管肺泡灌洗液中IL-17、IL-8、IL-4的水平,探討以上炎癥因子在支氣管哮喘發(fā)病中的可能作用機(jī)制,為其臨床治療提供理論依據(jù),現(xiàn)報道如下。

1.1 一般資料
隨機(jī)選取的該院2013年1月—2014年1月收治的支氣管哮喘患者共30例納入觀察組,其中男15例,女15例,年齡19 ~57歲,平均(34.9±7.1)歲。將同期在該院行健康體檢的30例健康志愿者納入對照組,其中男22例,女8例,年齡20~56歲,平均(35.5±6.8)歲。兩組觀察對象的年齡、性別比較,差異無統(tǒng)計學(xué)意義(P >0. 05),符合隨機(jī)、對照分組原則[3]。
