Tracheobronchial involvement of relapsing polychondritis

Area of Science:

• Rheumatology
• Pulmonology
• Internal Medicine

Background:

• Tracheobronchial involvement is a significant complication in relapsing polychondritis, affecting 20-50% of patients.
• This involvement can manifest at diagnosis or during disease progression, necessitating vigilant surveillance.

Purpose of the Study:

• To highlight the distinct clinical features, management strategies, and prognostic implications of tracheobronchial involvement in relapsing polychondritis.
• To emphasize the importance of early detection and appropriate diagnostic workup for airway complications.

Main Methods:

• Review of clinical characteristics, therapeutic approaches, and disease evolution in relapsing polychondritis patients with tracheobronchial involvement.
• Diagnostic confirmation using computed tomography (CT) scans with specific protocols and pulmonary function tests.
• Consideration of bronchoscopy with caution, emphasizing expert evaluation of risks and benefits.

Main Results:

• Tracheobronchial involvement presents unique clinical characteristics and requires tailored management.
• Early identification through imaging and pulmonary function tests, even in asymptomatic individuals, is vital.
• Interventional fiberoptic bronchoscopy has improved prognosis, but morbidity and mortality remain elevated.

Conclusions:

• Tracheobronchial involvement in relapsing polychondritis is a distinct entity requiring proactive screening and management.
• While advancements have been made, vigilant monitoring and cautious endoscopic interventions are key to mitigating severe outcomes.
