美国胸科学会/欧洲呼吸学会声明:对临床哮喘试验和临床实践中的哮喘控制和恶化进行标准化
2009/08/11
背景:在对患者治疗和临床试验过程中,哮喘的控制情况对评价哮喘治疗反应都至关重要。先前对哮喘的控制、严重程度及恶化的定义和评价存在多种方式。
目的:组建任务小组,在临床试验或临床实践中,为成人及年龄大于或等于6岁儿童的哮喘控制、严重程度及恶化相关的疾病治疗效果的标准化提供建议。
方法:采用描述性文献综述形式,评价检测手段的特性,以及评价与哮喘控制、恶化相关的疾病治疗效果检测手段的优缺点。本综述关注饮食参数、生理检测指标、综合评分、生物标记物、生活质量问卷调查及间接检测指标。
结果:基于目前治疗原则和临床及实验研究,任务小组对哮喘控制、严重程度和恶化进行了重新定义。由于目前对于哮喘及哮喘控制存在多个定义,因而没有任何一个单一的疾病治疗效果检测手段能对哮喘控制进行充分评价。在临床试验及临床实践中,对哮喘控制的评价应该包括:哮喘治疗的目标(即临床得到最佳控制)及减少未来出现不良后果的风险。不管基线状态还是对治疗反应进行评价时,该建议在临床试验及临床实践中都能有效评价哮喘控制。
结论:在临床试验的设计、指导及评价以及临床实践中,任务小组的推荐意见为临床医生、研究者及其它相关团体为哮喘的多元化评价奠定了基础。

An official American Thoracic Society/european Respiratory Society statement: asthma control and exacerbations: standardizing endpoints for clinical asthma trials and clinical practice.

BACKGROUND: The assessment of asthma control is pivotal to the evaluation of treatment response in individuals and in clinical trials. Previously, asthma control, severity, and exacerbations were defined and assessed in many different ways.
PURPOSE: The Task Force was established to provide recommendations about standardization of outcomes relating to asthma control, severity, and exacerbations in clinical trials and clinical practice, for adults and children aged 6 years or older.
METHODS: A narrative literature review was conducted to evaluate the measurement properties and strengths/weaknesses of outcome measures relevant to asthma control and exacerbations. The review focused on diary variables, physiologic measurements, composite scores, biomarkers, quality of life questionnaires, and indirect measures.
RESULTS: The Task Force developed new definitions for asthma control, severity, and exacerbations, based on current treatment principles and clinical and research relevance. In view of current knowledge about the multiple domains of asthma and asthma control, no single outcome measure can adequately assess asthma control. Its assessment in clinical trials and in clinical practice should include components relevant to both of the goals of asthma treatment, namely achievement of best possible clinical control and reduction of future risk of adverse outcomes. Recommendations are provided for the assessment of asthma control in clinical trials and clinical practice, both at baseline and in the assessment of treatment response.
CONCLUSIONS: The Task Force recommendations provide a basis for a multicomponent assessment of asthma by clinicians, researchers, and other relevant groups in the design, conduct, and evaluation of clinical trials, and in clinical practice.
