Overview
Relapsing polychondritis (RP) is a rare autoimmune disorder characterized by recurrent inflammation of cartilaginous structures, including the larynx, leading to symptoms such as hoarseness, airway obstruction, and pain 1.Diagnosis
Clinical Presentation: Hoarseness, dysphagia, and airway compromise 1.
Imaging: Laryngoscopy to visualize laryngeal cartilage inflammation and structural changes 1.
Laboratory Tests: Elevated inflammatory markers (ESR, CRP) and potential presence of ANCA (antineutrophil cytoplasmic antibodies) 1.
Histopathology: Biopsy may show characteristic inflammatory changes in affected cartilaginous tissues 1.Management
First-Line Treatments:
- Corticosteroids: High-dose glucocorticoids (e.g., prednisone) to control inflammation 1.
Adjunctive Treatments:
- Immunosuppressive Agents: Methotrexate, azathioprine, or cyclophosphamide for refractory cases 1.
- Biologic Agents: TNF inhibitors or IL-6 inhibitors in severe refractory disease 1.Special Populations
Pregnancy: Limited data; close monitoring and individualized treatment plans are recommended due to potential risks of immunosuppression 1.
Elderly: Careful consideration of comorbidities and potential drug interactions when selecting immunosuppressive therapies 1.Key Recommendations
Initiate high-dose corticosteroids for acute laryngeal involvement in relapsing polychondritis to manage inflammation effectively (Evidence: Strong 1).
Consider immunosuppressive therapy (e.g., methotrexate) for patients with recurrent or refractory laryngeal symptoms (Evidence: Moderate 1).
Monitor closely for complications in pregnant patients with relapsing polychondritis, tailoring treatment to minimize risk to both mother and fetus (Evidence: Expert opinion 1).References
