Introduction
Exercise-induced laryngeal obstruction (EILO) is a condition that often masquerades as asthma, leading to misdiagnosis and inappropriate treatment. The recent study titled Characteristics and impact of exercise-induced laryngeal obstruction: an international perspective provides a comprehensive overview of EILO's characteristics and its global impact. This blog aims to help practitioners improve their skills by implementing the outcomes of this research or by encouraging further investigation into EILO.
Key Findings from the Research
The study involved 1007 individuals, revealing that 58% were diagnosed with EILO. A significant finding was that EILO is often misdiagnosed as asthma, with a median delay of two years in diagnosis. This delay results in unnecessary asthma treatment for 20% of the patients.
Key characteristics of EILO include:
- Predominance in females (71%)
- Most common in adolescents and young adults
- 60% of cases involve supraglottic collapse
- 45% of individuals with EILO participate in recreational sports
Implications for Practitioners
Practitioners should be aware of the common misdiagnosis of EILO as asthma. The study highlights the importance of accurate diagnosis through continuous laryngoscopy during exercise (CLE) testing, which is the gold standard for identifying EILO.
Here are some steps practitioners can take to improve outcomes for patients with suspected EILO:
- Enhance Diagnostic Accuracy: Incorporate CLE testing into the diagnostic process for patients with exertional breathlessness and wheeze.
- Educate Patients: Inform patients about the differences between EILO and asthma to prevent unnecessary anxiety and treatment.
- Multidisciplinary Approach: Consider a team-based approach involving speech and language therapy, respiratory physiotherapy, and biofeedback to manage EILO effectively.
Encouraging Further Research
While this study provides valuable insights, there is a need for further research to explore the pathophysiology and optimal treatment strategies for EILO. Practitioners are encouraged to contribute to this field by conducting studies that could lead to improved diagnostic tools and therapeutic approaches.
Conclusion
The international perspective on EILO provided by this study underscores the importance of accurate diagnosis and appropriate management. By understanding the characteristics and impact of EILO, practitioners can enhance clinical outcomes and reduce the incidence of misdiagnosis.
