Relapsing polychondritis is a rare autoimmune condition causing cartilage inflammation, primarily affecting the ears and nose. Early recognition and treatment are crucial to prevent severe complications like airway obstruction and joint damage.

Area of Science:

  • Rheumatology
  • Immunology
  • Genetics

Background:

  • Relapsing polychondritis (RP) is a rare systemic autoimmune disease characterized by progressive inflammation and destruction of cartilaginous tissues.
  • The condition often presents with auricular chondritis, mimicking infectious cellulitis, and can lead to characteristic deformities such as cauliflower ear and saddle nose.
  • Pathological findings include antibodies against type II collagen, suggesting an autoimmune basis targeting cartilage components.

Purpose of the Study:

  • To review the clinical manifestations, diagnostic challenges, and therapeutic strategies for relapsing polychondritis.
  • To highlight the diverse organ involvement beyond cartilage, including audiovestibular, cardiovascular, and neurological systems.
  • To emphasize the importance of early diagnosis and multidisciplinary management in improving patient outcomes.

Main Methods:

  • Systematic review of existing literature on relapsing polychondritis.
  • Analysis of clinical case reports and cohort studies.
  • Synthesis of data on epidemiology, pathogenesis, clinical features, and treatment modalities.

Main Results:

  • The most common initial presentation involves inflammation of the ears and nose, with earlobes typically spared.
  • Chronic disease can lead to significant physical deformities and functional impairments.
  • Systemic involvement extends to joints (arthritis), audiovestibular system, heart valves, and potentially neurological, ocular, and renal systems.
  • Acute tracheal cartilage involvement poses a risk of airway obstruction and secondary pulmonary infections.

Conclusions:

  • Relapsing polychondritis requires a high index of suspicion due to its rarity and varied presentation.
  • Corticosteroids are the mainstay of treatment, with various immunosuppressants and biologics used for refractory cases.
  • Comprehensive management involving rheumatologists, ENTs, and other specialists is essential for addressing the multisystemic nature of the disease.
