Brief summary

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.

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.

Interventions

DRUGFluticasone propionate 230mcg for 3 Months
DRUGCurrent 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.

DRUGSalmeterol 21mcg for 3 Months

Levels of Fractional Exhaled Nitric Oxide (FeNO)Week 12Measured 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.

Rhinosinusitis Score on International Classification of Sleep Disorders (ICSD)Week 12For 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).
Score on Leicester Cough Questionnaire (LCQ)Week 12For 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.
Score on Voice Handicap Index 10 (VHI-10)Week 12Voice 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.
Number of Participants With Positive Level of Paradoxical Vocal Fold Movement (PVFM)Week 12measured by laryngoscopic visualization at rest or after provocation with various odors or exercise.
