Uncontrolled Lower Respiratory Symptoms in the WTC Survivor Program

12 de enero de 2021 actualizado por: NYU Langone Health

Uncontrolled Lower Respiratory Symptoms in the World Trade Center 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.

Descripción general del estudio

Descripción detallada

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.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Comparador activo: Uncontrolled LRS
Patients who have uncontrolled lower respiratory symptoms (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.

Otro: 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.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Forced Oscillation Technique (FOT) Measures
Periodo de tiempo: Week 12
Small airway function measured pre/post BD (bronchodilator) impulse oscillometry at resistance 5 Hz (R5) and 5-20 Hz (R5-20).
Week 12
Spirometry Measures
Periodo de tiempo: 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

Week 12

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Number of Participants With Positive Level of Bronchial Hyperreactivity (BHR)
Periodo de tiempo: Week 12
To test whether bronchial Hyperreactivity (BHR), assessed by methacholine challenge, is associated with uncontrolled lower respiratory symptoms.
Week 12
Number of Participants With Positive Level of Paradoxical Vocal Fold Movement (PVFM)
Periodo de tiempo: Week 12
measured by laryngoscopic visualization at rest or after provocation with various odors or exercise.
Week 12
Total IgE (Immunoglobulin E) Levels
Periodo de tiempo: Week 1
IgE levels were obtained by blood test - the total amount of blood drawn is 30 mL.
Week 1
Total EoS (Eosinophil) Counts
Periodo de tiempo: Week 1
EoS counts were obtained by blood test - the total amount of blood drawn is 30 mL.
Week 1
Levels of Fractional Exhaled Nitric Oxide (FeNO)
Periodo de tiempo: 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.
Week 12
Score on Voice Handicap Index 10 (VHI-10)
Periodo de tiempo: 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.
Week 12
Rhinosinusitis Score on International Classification of Sleep Disorders (ICSD)
Periodo de tiempo: 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).
Week 12
Score on Leicester Cough Questionnaire (LCQ)
Periodo de tiempo: 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.
Week 12
