NCT03550456

Brief Summary

The purpose of this study is to investigate the quality of life of subjects suffering from dyspnoea while exercising and quantify the number of diagnoses of Exercise induced Asthma (EIA) and Exercise induced laryngeal obstruction (EILO) in our outpatient clinic using an exercise-challenge in a cold-chamber and an exercise-challenge with continuous laryngoscopy.

Outcome Measures

Primary Outcomes (1)

  • Quality of life in subjects with exercise induced asthma and exercise induced laryngeal obstruction

    The primary endpoint is the quality of life of all subjects with EIA and EILO assessed by questionnaires (Child Behavior Checklist (CBCL/4-18) for parents and Youth Self-Report (YSR 11-18) for adolescents) at the time of diagnosis and after therapy in accordance with the diagnosis with ICS/LABA combination or speech therapy. Both questionnaires are almost identical and contain 120 items (CBCL/4-18) and 119 items (YSR), respectively, in eight different categories: anxious/depressed, withdrawn/depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behavior, and aggressive behavior. Answers to each item are coded on a 3-point Likert-scale, 0 = not true, 1 = somewhat or sometimes true, 2 = very true or often true. Raw scores are transformed into T-scores to allow comparison with children from the same gender and age.

Study Arms (1)

ECC, ECC with CLE, speech therapy

After the standard diagnostic (spirometry, body plethysmography, exhaled NO, skin prick test) all patients with dyspnea while exercising undergo exercise challenges in a cold chamber (ECC). In case of a positive reaction in the ECC the patients get asthma medication (ICS/LABA combination). Both groups negative and positive should fill out a symptom diary and the next visit will be booked 6 weeks later. If they still have dyspnea while exercising with ICS/LABA combination or hat a negative ECC the patients undergo an ECC with continuous laryngoscopy. In case of an EILO diagnosis patients will be sent to speech therapy and checked at a follow up visit. All patients and their parents should complete questionnaires for symptoms and quality of life at every visit.

Interventions

ECCOTHER

Exercise challenge is defined as running on a treadmill for 6-8 minutes on submaximal work load in a cold chamber.

ECC, ECC with CLE, speech therapy

Continuous Laryngoscopy is endoscopy of the larynx used to obtain a view of laryngeal obstruction during exercise.

ECC, ECC with CLE, speech therapy

Patients with diagnosis of EILO will be sent to a speech therapist for at least 6 training sessions.
