Comparative effectiveness of environmental intervention and standard care in abil

描述（由申请人提供）：DiMango, Emily/Kattan， Meyer在本次申请中，我们提出了一项比较哮喘非药物治疗和标准药物治疗的临床研究试验。目标人群包括居住在曼哈顿、布朗克斯和纽约市区的市中心少数民族。该方案旨在确定旨在减少哮喘患者致敏的室内过敏原暴露的多层面环境干预是否比常规护理更有效地减少NAEPP，这是一种新颖但重要的结果测量方法。纽约曼哈顿的哥伦比亚大学医学中心和纽约布朗克斯的雅可比医院的合作将确保少数民族个体在这项重要的研究中得到代表。该协议涉及哮喘的一个主要公共卫生问题，这对整个哮喘人群至关重要，但对内城居民最为突出。这项拟议的研究严格测试了哮喘护理的国家指南，填补了在理解环境修复的重要性方面的空白，因为它与哮喘控制的药物治疗的需求相比。研究结果有可能影响公共卫生政策以及第三方医疗保险公司的报销。研究人员在这个应用程序中有设计和执行哮喘临床研究试验的能力，其跟踪记录超出了招聘的预期。具体而言，我们的研究旨在：i.)在为期48周的研究期内，通过一项针对过敏原敏感的哮喘患者的随机对照试验，确定旨在减少室内过敏原和刺激物暴露的环境干预是否比常规护理更有效地减少NAEPP基于步骤的治疗，ii)确定环境干预是否导致室内过敏原水平、过敏原特异性血清IgE水平、气道高反应性、一氧化氮部分排泄的降低。在48周的研究期间，与常规护理相比，痰嗜酸性粒细胞计数、哮喘症状评分、哮喘加重、治疗失败和肺功能改善；iii)确定随机接受环境干预的受试者与常规护理相比，哮喘控制所需的过敏原特异性IgE水平降低与NAEPP台阶水平降低之间是否存在关联。小灵通398/2590 （Rev. 11/07）页延续格式页

DESCRIPTION (provided by applicant): DiMango, Emily/Kattan, Meyer In this application, we propose a clinical research trial to compare non-pharmacologic therapy and standard pharmacologic therapy in asthma. The target population includes inner-city minority individuals living in Manhattan, the Bronx and the New York City area. This protocol is designed to determine whether multi- faceted environmental intervention aimed at reducing exposure to indoor allergens to which asthmatic patients are sensitized is more effective than usual care in reducing NAEPP step based therapy, a novel, but important outcome measure. Collaboration of Columbia University Medical Center in Manhattan, New York and Jacobi Hospital in the Bronx, New York will ensure that minority individuals are represented in this important study. The protocol involves a major public health concern in asthma, one that is critical for the entire asthma population, but is most salient for residents of inner cities. The proposed study rigorously tests national guidelines in asthma care and fills a gap in understanding the importance of environmental remediation as it compares with need for pharmacological therapy for asthma control. Results of the study have the potential to affect public health policy as well as reimbursement from third party health care insurance companies. Investigators in this application have the proven ability to design and execute clinical research trials in asthma, with a track record that exceed expectations for recruitment. Specifically, our study aims to: i.) determine via a randomized, controlled trial in allergen-sensitized asthmatic patients whether environmental intervention aimed at reducing exposure to indoor allergens and irritants is more effective in reducing NAEPP step based therapy than usual care over a 48 week study period, ii) determine if environmental intervention leads to reduction in indoor allergen levels, allergen- specific serum IgE levels, airway hyperresponsiveness, fractional excretion of nitric oxide, sputum eosinophil count, asthma symptom score, asthma exacerbations, treatment failures and improved lung function compared to usual care over a 48 week study period and iii) determine if there is an association between reduction in allergen specific IgE level and reduction in NAEPP step level required for asthma control among subjects randomized to environmental intervention compared with usual care.
