研究目的:

1、评价初诊轻度支气管哮喘初始治疗时给予4周维持低剂量ICS/LABA对比按需低剂量ICS/LABA在轻度哮喘患者中的疗效,明确4周FEV1较基线改善情况,及对气道可逆性及气道炎症水平的改善,确立药物疗效的最佳人群和最佳治疗方案; 2、基于肺功能全参数(大气道参数:FEV1, FEV1/FVC;峰流速:PEF;小气道参数:FEF25%, FEF50%, FEF75%, MMEF)和气道炎症水平等多维评估,探索可有效预测维持低剂量ICS/LABA治疗在轻度初诊哮喘患者中疗效的生物标志物; 3、初始维持低剂量ICS/LABA治疗4W,后续按需该药物治疗至24W,对比初始即按需低剂量ICS/LABA治疗至24W,在24W研究中引入移动肺功能,动态监测大小气道功能全参数及临床指标,探索早期维持低剂量ICS/LABA+后续按需治疗在轻度哮喘中对FEV1较基线改善率、急性发作风险指标、气道炎症影响,并建立急性发作预测模型。  

Objectives of Study:

1.Evaluate the efficacy of 4 weeks of maintenance therapy with low-dose ICS/LABA versus as-needed low-dose ICS/LABA in newly diagnosed mild asthma patients. Assess the improvement in FEV1 from baseline over 4 weeks, and the impact on airway reversibility and inflammation levels. Identify the optimal patient population and treatment regimen for the medication. 2.Based on a comprehensive evaluation of pulmonary function parameters (including large airway parameters: FEV1, FEV1/FVC; peak flow: PEF; small airway parameters: FEF25%, FEF50%, FEF75%, MMEF) and airway inflammation levels, explore biomarkers that can effectively predict the efficacy of maintenance therapy with low-dose ICS/LABA in newly diagnosed mild asthma patients. 3.Compare 4 weeks of initial maintenance therapy with low-dose ICS/LABA followed by as-needed medication until 24 weeks with as-needed low-dose ICS/LABA therapy until 24 weeks. In the 24-week study, incorporate mobile lung function monitoring to dynamically assess large and small airway function parameters and clinical indicators. Explore the impact of early maintenance therapy with low-dose ICS/LABA followed by as-needed treatment on FEV1 improvement from baseline, acute exacerbation risk indicators, and airway inflammation, and develop a model to predict acute exacerbations.
