  Purpose
The purpose of this study is to understand why patients in the World Trade Center program have continuing breathing problems. This study will improve investigators understanding of breathing problems among individuals with World Trade Center exposure by allowing them to review and monitor medication use, lung function, and examine other conditions that can contribute to problems with breathing. The findings from the study will help investigators understand why some people have persistent lower respiratory symptoms (breathing problems) after their exposure to World Trade Center dust and fumes, and may help guide better management and treatment of these symptoms.

Further study details as provided by New York University School of Medicine:

Primary Outcome Measures:
  • Change in measures of airflow and lung volumes by spirometry and small airway dysfunction by impulse oscillometry and association with uncontrolled lower respiratory symptoms [ Time Frame: Week 1, Week 12 ]
    To test whether measurements of airflow and lung volume (spirometry) and of small airway dysfunction (impulse oscillometry) are associated with uncontrolled lower respiratory symptoms

  • Change in lower respiratory symptom control status [ Time Frame: Week 1, Week 12 ]
    To test whether a 3-month treatment with combined high-dose inhaled corticosteroids and long-acting bronchodilators results in improved lower respiratory symptoms, assessed by the Asthma Control Test and the Asthma Symptom Utility Index


Secondary Outcome Measures:
  • Bronchial Hyperresponsiveness [ Time Frame: Week 8 ]
    To test whether bronchial hyperresponsiveness (BHR), assessed by methacholine challenge, is associated with uncontrolled lower respiratory symptoms

  • Inflammatory Markers Associated with Airway Disease (CRP, RAST, Eos and Periostin) [ Time Frame: Week 1 ]
    To compare levels of circulating biomarkers associated with a Th2 inflammatory response (total and allergen-specific IgE, circulating eosinophils, C-reactive protein, serum periostin) in patients with uncontrolled lower respiratory symptoms and controlled lower respiratory symptoms. The total amount of blood drawn will be 30 mL.

  • Gastroesophageal reflux symptoms [ Time Frame: Week 1 ]
    To compare rates of gastroesophageal reflux symptoms, assessed by questionnaire, in patients with uncontrolled lower respiratory symptoms and controlled lower respiratory symptoms

  • Chronic rhinosinusitis symptoms [ Time Frame: Week 1 ]
    To compare rates of chronic rhinosinusitis symptoms, assessed by questionnaire, in patients with uncontrolled lower respiratory symptoms and controlled lower respiratory symptoms

  • Paradoxical vocal cord motion (PVCM) [ Time Frame: Week 12 ]
    To compare rates of paradoxical vocal cord motion, assessed by videolaryngostroboscopy with provocation, in patients with uncontrolled lower respiratory symptoms and controlled lower respiratory symptoms.

  • Changes in levels of fractional exhaled nitric oxide (FeNO) [ Time Frame: Week 1, Week 12 ]
    To compare levels of an exhaled marker of inflammation (Fractional exhaled nitric oxide; FeNO) in patients with uncontrolled lower respiratory symptoms and controlled lower respiratory symptoms at baseline and at the end of the 3 month course of treatment.

  • Dyspnea and Functional status [ Time Frame: Week 12 ]
    To assess dyspnea and functional status using the 6 minute walk test between subjects with uncontrolled and controlled lower respiratory symptoms at the end of the 3 month course of treatment.


Estimated Enrollment: 300
Study Start Date: January 2014
Estimated Study Completion Date: November 2018
Estimated Primary Completion Date: February 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Visit 1 Uncontrolled LRS
Patients who have uncontrolled LRS (ACT < 20) at time of Visit 1 will be provided with study Advair (Fluticasone propionate 230mcg/salmeterol 21mcg) for a total of 3 months and receive medication adherence counseling Patients who have uncontrolled LRS at V1, but do not fit criteria for Step 3,4 or 5 asthma therapy according to NIH EPR III asthma guidelines will be deferred from the study until they have been seen by their physician and tried on ICS therapy.
Drug: Fluticasone propionate 230mcg for 3 Months
Other Name: Advair HFA
Drug: Salmeterol 21mcg for 3 Months
Visit 1 Controlled LRS
Patients who had symptoms at monitoring visit but are now controlled at V1 will be asked to continue their current treatment (or no treatment) and will continue with the study. They will not be provided with any medications.
Drug: Current Treatment or no treatment
Patients who had symptoms at monitoring visit but are now controlled at V1 will be asked to continue their current treatment (or no treatment) and will continue with the study. They will not be provided with any medications.

Detailed Description:
Investigators will conduct a clinical study with aggressive treatment for lower respiratory symptoms in patients in the World Trade Center Environmental Health Center. Patients in the WTC EHC with uncontrolled LRS at visit 1 will be identified and placed on high-dose inhaled corticosteroids and long-acting beta agonists for three months. Adherence will be assessed at monthly visits. Patients will perform spirometry and oscillometry at baseline and after 3 months of treatment. They will also be assessed for markers of airway inflammation, bronchial hyperresponsiveness and co-morbid conditions including depression,anxiety,post-traumatic stress disorder, gastroesophageal reflux, paradoxical vocal cord motion and rhinosinusitis.
