“…The remaining 29 studies used a 6‐ to 8‐min free running test to diagnose EIB. If environmental conditions (temperature and humidity), exercise intensity, and airway status are controlled, the free running test may have a similar diagnostic profile as a standardized exercise test to identify individuals with EIB . However, the free running test was conducted outdoors in most of these 29 studies, and such a test might overestimate the prevalence rate of EIB…”

“…Unfortunately, the sensitivity of a positive test is rather low, which limits its use as a screening tool for asthma. [18][19][20][21][22][23] In the literature, no data are available on the positive predictive value of respiratory signs and symptoms such as premature arrest, breathlessness, cough, wheezing, and chest tightness to detect EIA. Reliable signs and symptoms could help differentiate children with EIA from children with decreased exercise tolerance for other reasons.…”

Exercise-induced asthma (EIA) is a possible cause of poor physical performance in children. No data are available on the value of respiratory symptoms to discriminate children with bad physical fitness from children with EIA. We evaluated respiratory symptoms in school-age children during and after exercise in relation to EIA. The population of 149 primary schools (849 classes with 15,241 children) was enrolled in the study. EIB was assessed using the 6-min free-running-test (6MFRT) in 15,241 children. At the end or at premature arrest of the 6MFRT, signs reported by the children and clinical symptoms observed by supervising physicians were recorded. Peak flow measurements were obtained before and 5 and 10 min after the 6MFRT, a decrease of 15% or more being defined as significant. The 6MFRT was positive in 7.4% of primary schoolchildren. Girls were more likely to have a positive test than boys (8.5% vs. 6.4%, P < 0.001), and children living in urban areas more than those living in rural areas (8.9% vs. 7.0%, P < 0.01). Premature arrest was seen in 3.5% (i.e., n = 353) of the children. The main reasons for premature arrest were dyspnea and chest pain. Among them, only 21% had a positive 6MFRT, while 89% with a positive 6MFRT could terminate the test. Premature arrest, breathlessness, chest tightness, wheezing, and cough had a positive predictive value to detect a EIA of 21.9%, 20.8%, 36.4%, 41.2%, and 28.3%, respectively, and a sensitivity of 10.8%, 29.5%, 14.9%, 4.8%, and 13.0%, respectively. In conclusion, EIA was detected in 7.4% of schoolchildren. A slightly higher incidence was observed in girls and children from an urban area. Neither premature arrest nor clinical signs and symptoms were good predictors of EIA in primary schoolchildren.

“…Crucial in this context is the ability of the test set-up to facilitate sustained maximal efforts (beyond the aerobic threshold) for as long as necessary to induce symptoms. This might be more easily achieved if using free running or other 'in the field' techniques, as has been addressed in studies of exercise induced asthma [22]; however, this scenario has not been studied in relation to EILO.…”

Inducible laryngeal obstruction: an official joint European Respiratory Society and European Laryngological Society statement

et al. 2017

Inducible laryngeal obstruction (ILO) describes an inappropriate, transient, reversible narrowing of the larynx in response to external triggers. ILO is an important cause of a variety of respiratory symptoms and can mimic asthma. Current understanding of ILO has been hampered by imprecise nomenclature and variable approaches to assessment and management. A task force of the European Respiratory Society (ERS) and European Laryngological Society (ELS) was thus set up to address this, and to identify research priorities.A literature search identified relevant articles published until June 2016, using all identifiable terms for ILO, although including only articles using laryngoscopy. In total, 172 out of 252 articles met the inclusion criteria, summarised in sections on diagnostic approach, aetiology, comorbidities, epidemiology and treatment. The consensus taxonomy published by ERS, ELS and the American College of Chest Physicians (ACCP) in 2015 is used throughout this statement.We highlight the high prevalence of ILO and the clinical impact for those affected. Despite recent advances, most aspects of this condition unfortunately remain incompletely understood, precluding firm guidance. Specifically, validated diagnostic and treatment algorithms are yet to be established, and no randomised control studies were identified in this search; hence we also make recommendations for future research.
