摘要 目的:比较具有气道可逆性差异的慢性阻塞性肺疾病(COPD)患者呼出气冷凝液(EBC)中白三烯B4(LTB4)含量,了解对支气管舒张剂不同反应的COPD患者气道炎症的关系,探讨EBC分析对COPD表型研究的价值。方法:用酶免疫测定法测定EBC中LTB4的浓度,用统计学方法比较各组之间的差异性。结果:支气管舒张试验阴性COPD较哮喘低;差异有统计学意义(P<0.05);支气管舒张试验阳性的COPD较支气管舒张试验阴性的COPD者高;差异有统计学意义(P<0.05)。结论:对支气管舒张剂具有可逆性反应的COPD和哮喘气道炎症的机制可能有一定的重叠。EBC分析对COPD表型研究可能具有一定价值。
