哮喘患者能从同时采用桉树脑治疗中获益:安慰剂-对照、双盲试验
2012/11/19
摘要
背景和目的:桉树脑是桉树油的主要组成成分,作为粘液溶解剂用于炎症性气道疾病的治疗。由于桉树脑具有粘液溶解性、支气管扩张性和抗炎作用,因而可降低慢性阻塞性肺疾病患者的疾病发作率。基于桉树脑的上述药理学作用,我们认为,哮喘患者也应该能从同时采用桉树脑治疗中获益。
方法:作为双盲、安慰剂-对照、多中心研究的一部分,基于本研究指南,随机入选确诊哮喘的247名患者。所有患者采用200 mg桉树脑或安慰剂同时治疗,每日3次,持续6周。联合主要转归指标包括肺功能、哮喘症状和生活质量。
结论:为期6个月的治疗后,桉树脑治疗组患者联合主要转归指标较安慰剂组显著改善(P=0.0027)。基于Wei-Lachin程序,具体主要转归指标也显著改善(FEV1:P=0.0398;哮喘症状:P=0.0325;哮喘生活质量问卷调查[AQLQ]:P=0.0475)。
结论:同时采用桉树脑治疗哮喘可显著改善哮喘患者的肺功能、健康状况和降低呼吸困难的发生。

Abstract
BACKGROUND AND AIMS:Cineole is the main constituent of eucalyptus oil, and it is mainly used as a mucolytic agent in inflammatory airway diseases. With its known mucolytic, bronchodilating, and anti-inflammatory effects, cineole reduces the exacerbation rate in patients suffering from chronic obstructive pulmonary disease. Based on these pharmacodynamic effects, we arrived at the hypothesis that asthma patients would benefit from concomitant therapy with cineole.
METHODS:As part of a double-blind, placebo-controlled, multicenter study, 247 patients with confirmed asthma were randomly selected according to the guidelines for this study. All patients were administered 200 mg of cineole, or a placebo, three times per day as a concomitant therapy over a period of 6 months. The combined primary outcome measures, which were implemented as a multiple criteria testing process, were improvement of lung function, asthma symptoms, and quality of life.
RESULTS:Following the completion of the 6-month treatment period, it was noted that the patient group treated with cineole showed significantly more improvements to the multiple testing criteria than the patients in the placebo group (p = .0027). The statistical significance of the individual outcome measures could also be proven in accordance with the Wei-Lachin procedure (i.e., for Forced expiratory Volume 1 Second, p = .0398; for asthma symptoms, p = .0325; and for Asthma Quality of Life Questionnaire (AQLQ), p = .0475).
CONCLUSION:Concomitant therapy using cineole can lead to notable improvement in lung function and health condition as well as to reduce dyspnea in asthma patients.
