Uncontrolled Lower Respiratory Symptoms in the WTC Survivor Program

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.

Key information

About this study

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.

Treatment and study plan

Fluticasone propionate 230mcg for 3 Months

Drug

Other names: Advair HFA

Current Treatment or no treatment

Drug

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.

Salmeterol 21mcg for 3 Months

Drug

Primary outcomes

  1. Forced Oscillation Technique (FOT) Measures

    Time frame: Week 12

    Small airway function measured pre/post BD (bronchodilator) impulse oscillometry at resistance 5 Hz (R5) and 5-20 Hz (R5-20).

  2. Spirometry Measures

    Time frame: Week 12

    Measured pre/post BD (bronchodilator). Reported as ratio: %FEV1(Liters)/FVC(Liters).

    FEV1 = forced expiratory volume at 1 second FVC = forced vital capacity

Secondary outcomes

  1. Number of Participants With Positive Level of Bronchial Hyperreactivity (BHR)

    Time frame: Week 12

    To test whether bronchial Hyperreactivity (BHR), assessed by methacholine challenge, is associated with uncontrolled lower respiratory symptoms.

  2. Number of Participants With Positive Level of Paradoxical Vocal Fold Movement (PVFM)

    Time frame: Week 12

    measured by laryngoscopic visualization at rest or after provocation with various odors or exercise.

  3. Total IgE (Immunoglobulin E) Levels

    Time frame: Week 1

    IgE levels were obtained by blood test - the total amount of blood drawn is 30 mL.

  4. Total EoS (Eosinophil) Counts

    Time frame: Week 1

    EoS counts were obtained by blood test - the total amount of blood drawn is 30 mL.

  5. Levels of Fractional Exhaled Nitric Oxide (FeNO)

    Time frame: Week 12

    Measured using a portable device that measures the level of nitric oxide in parts per billion (PPB) in the air slowly exhaled out of the patient's lungs.

  6. Score on Voice Handicap Index 10 (VHI-10)

    Time frame: Week 12

    Voice Handicap Index 10 is a measure of laryngeal dysfunction or hypersensitivity to capture the "overall" state of voice handicap. The normative value for this instrument is 2.83, with a score > 11 considered abnormal. There are 10 statements that are scored between 0 and 4 (0= never, 4= always). The total range is 0-40, where 40 is highest level of dysfunction.

  7. Rhinosinusitis Score on International Classification of Sleep Disorders (ICSD)

    Time frame: Week 12

    For rhinosinusitis symptoms, the ICSD scoring system was used, with a likert scale of 1-10 for each symptom (total range of scale = 1-60, with higher scores reflecting more symptoms).

  8. Score on Leicester Cough Questionnaire (LCQ)

    Time frame: Week 12

    For rhinosinusitis symptoms, the Leicester Cough Questionnaire (LCQ) was used - a cough-specific health status questionnaire that assesses the physical, psychological, and social domains of cough. The LCQ is made up of 19 items; the total score range is 3-21; a higher score is associated with better health.
