“…Induced Laryngeal Obstruction (ILO) is a respiratory disorder involving episodic abnormal laryngeal adduction upon inhalation that restricts airway opening and airflow. [1][2][3][4][5] The condition results in dyspnea. 6 Symptoms often include a sensation of throat tightness, inspiratory stridor, cough, dysphonia, chest tightness, respiratory distress, and/or lightheadedness.…”

“…[38][39][40][41] Although formal behavioral health testing in pediatric patients has not been widely reported, evidence suggests a high prevalence of behavioral health comorbidities in individuals with EILO/ILO. 9,42,43 Patients with EILO have been observed seperately, 3,23,44,45 however, the 2 conditions have frequently been considered as one in research and clinical contexts. 13,18 As such, it is unclear to what extent EILO, ILO, and EILO+ differ one from another.…”

Purpose: To compare clinical profiles of pediatric patients with Induced Laryngeal Obstruction (ILO), Exercise Induced Laryngeal Obstruction (EILO), and EILO with non-exertion related secondary triggers (EILO+). Methods: A retrospective observational cohort design was employed. Four-hundred and twenty-three patients <18 years of age were identified from the electronic medical record of a large children’s hospital. All patients underwent evaluations with a laryngologist and speech-language pathologist and were diagnosed with EILO/ILO. Patients were divided into 3 groups based on dyspnea triggers reported in initial evaluations. Groups consisted of patients with EILO (N = 281), ILO (N = 30), and EILO+ (N = 112). Patient demographics, EILO/ILO symptoms, endoscopy findings, medical comorbidities, medical history, and EILO/ILO treatment information were extracted and compared across EILO/ILO subtypes. Results: Patients with EILO experienced higher rates of hyperventilation ( P < .001), sore throat ( P = .023), and chest pain ( P = .003). Patients with ILO were significantly younger in age ( P = .017) and presented with increased rates of nighttime symptoms ( P < .001), globus sensation ( P = .008), self-reported reflux symptoms ( P = .023), and history of gastrointestinal conditions ( P = .034). Patients with EILO+ were more likely to be female ( P = .037) and presented with higher prevalence of anxiety ( P = .003), ADHD ( P = .004), chest tightness ( P = .030), and cough ( P < .001). Conclusions: Patients with EILO, ILO, and EILO+ present with overlapping but unique clinical profiles. A prospective study is warranted to determine the etiology of these differences and clarify how the efficacy of EILO, ILO, and EILO+ treatment can be maximized. Level of Evidence: 4
