Bronchial responsiveness to histamine was measured in 35 adult asthmatics whose symptoms were controlled on a minimum of medication. The tests were carried out on two occasions separated by 10-30 months. On each occasion the subjects had no symptoms of respiratory infection and no exposure to relevant allergens for at least six weeks. Bronchial responsiveness did not change in those who required no medication or inhaled salbutamol only to control their symptoms, but was significantly improved in those who required continuous treatment with both beclomethasone and salbutamol (p = 0.03). The results suggest that non-specific bronchial responsiveness remains similar over long periods when exacerbating factors are not present and that treatment with beclomethasone may reduce hyperresponsiveness.
对35名成年哮喘患者进行了组胺支气管反应性测定,这些患者的症状通过最少药物得以控制。测试分两次进行,间隔10 - 30个月。每次测试时,受试者均无呼吸道感染症状,且至少六周未接触相关过敏原。对于那些无需用药或仅吸入沙丁胺醇来控制症状的患者,支气管反应性未发生变化,但对于那些需要同时使用倍氯米松和沙丁胺醇进行持续治疗的患者,支气管反应性有显著改善(p = 0.03)。结果表明,在不存在加重因素时,非特异性支气管反应性在长时间内保持相似,且倍氯米松治疗可能会降低高反应性。
