With mucosal inflammation contributing to the pathogenesis of asthma, it is increasingly accepted that long term steroid inhalers may induce remission in chronic long standing asthmatics. The present study involved 44 stable asthmatics who were randomly given either beclomethasone dipropionate inhaler (50 ug) 2 puffs qds or salbutamol inhaler (100 mcg) 2 puffs tds in addition to their oral bronchodilators. Pulmonary function testing, bronchoalveolar lavage and complete blood count were done at basal and weekly intervals and at the end of the study. The absolute eosinophil count showed a significant drop in the beclomethasone group as compared to the salbutamol group. Serial lung functions showed a significant improvement in the pre-bronchodilator PEFR and the pre-bronchodilator FVC in the beclomethasone group as compared to the salbutamol group. There was no significant change in the lavage eosinophil count pre and post-bronchodilator in both groups. Steroid inhalers are thus useful in long term management of bronchial asthma especially with respect to reducing bronchodilator requirement.
由于黏膜炎症在哮喘发病机制中起作用,长期使用类固醇吸入器可能使慢性长期哮喘患者病情缓解这一观点越来越被认可。本研究纳入了44名病情稳定的哮喘患者,除口服支气管扩张剂外,他们被随机给予二丙酸倍氯米松吸入器(50微克)每日4次、每次2喷或沙丁胺醇吸入器(100微克)每日3次、每次2喷。在基线、每周以及研究结束时进行肺功能测试、支气管肺泡灌洗和全血细胞计数。与沙丁胺醇组相比,倍氯米松组的绝对嗜酸性粒细胞计数显著下降。与沙丁胺醇组相比,倍氯米松组的系列肺功能显示,支气管扩张剂使用前的呼气峰流速(PEFR)和用力肺活量(FVC)有显著改善。两组支气管扩张剂使用前后的灌洗嗜酸性粒细胞计数均无显著变化。因此,类固醇吸入器在支气管哮喘的长期管理中是有用的,特别是在减少支气管扩张剂需求方面。
