    Relapsing polychondritis (RP) causes airway inflammation. Physiologic and radiologic studies help diagnose upper airway obstruction in RP patients, guiding treatment strategies.

    Area of Science:

    • Pulmonary Medicine
    • Rheumatology
    • Medical Imaging

    Background:

    • Relapsing polychondritis (RP) is a rare autoimmune disease causing progressive inflammation of cartilaginous structures.
    • Respiratory involvement in RP can lead to significant upper airway obstruction.
    • Accurate diagnosis of airway obstruction site and nature is crucial for patient management.

    Observation:

    • Five patients with respiratory involvement due to relapsing polychondritis underwent detailed physiologic and radiologic assessments.
    • Maximal expiratory and inspiratory flow-volume loops, along with airway resistance measurements, were utilized.
    • Advanced imaging techniques including CT scans and cinetracheography were employed when necessary.

    Findings:

    • Flow-volume loops and airway resistance provide initial clues to the presence, site, and type (fixed or dynamic) of upper airway obstruction in RP.

  • Fixed upper airway obstruction or complex lesions often require advanced imaging like CT scans, cinetracheography, or laryngotracheograms.
  • These imaging modalities are essential for precise localization and characterization of obstruction in challenging cases.

    • Implications:

    • Early and accurate diagnosis of airway obstruction in RP is vital for effective therapeutic interventions.
    • Integrating pulmonary function tests with advanced imaging improves diagnostic accuracy for RP-related airway compromise.
    • This diagnostic approach aids in tailoring treatment and improving outcomes for patients with relapsing polychondritis affecting the respiratory tract.
