Severe asthma cases may be misdiagnosed vocal cord dysfunction. This condition causes atypical breathing issues and can be triggered by exercise, impacting steroid treatment effectiveness.

Area of Science:

  • Pulmonology
  • Otolaryngology

Background:

  • Severe asthma often requires long-term corticosteroid therapy.
  • Corticosteroid resistance in asthma presents a significant clinical challenge.

Observation:

  • A patient presented with severe dyspneic attacks, initially presumed to be cortico-resistant asthma.
  • Symptoms included atypical dyspnea, dysphonia, and syncopes, disproportionate to lung function tests.

Findings:

  • Specialized ENT examination confirmed vocal cord dysfunction (VCD).
  • VCD involved paradoxical inspiratory vocal cord adduction triggered by exercise.

Implications:

  • This case highlights the importance of considering VCD in atypical severe asthma presentations.
  • Effective VCD management, including speech therapy and psychotherapy, may reduce reliance on steroid treatments.
