Overview
Relapsing polychondritis is a condition where cartilage deteriorates.
It is also known as Chronic atrophic polychondritis, Meyenburg-Altherr-Uehlinger syndrome, von Meyenburg's disease, Generalized chondromalacia, or Systemic chondromalacia.
Historical Perspective
Classification
Polychondritis is one of many subclasses of disease in the area of Rheumatology.
Pathophysiology
- The pathogenesis of relapsing polychondritis is characterized by [feature1], [feature2], and [feature3].
- The [gene name] gene/Mutation in [gene name] has been associated with the development of [disease name], involving the [molecular pathway] pathway.
- On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
- On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Causes
Reasons for disease onset are not known.
It is considered to possibly be an auto-immune disease[1] in which the human's body's immune system begins to attack and destroy the cartilage tissues in the body.
Differentiating Relapsing Polychondritis from other Diseases
- Cauliflower ear
- Chondritis
- Chondromdermatitis
- Hansen's disease
- Nodularis helicis
- Perichondritis
- Rhinophyma
- Skin cancer
- Syphilis
Epidemiology and Demographics
- The prevalence of [disease name] is approximately [number or range] per 100,000 individuals worldwide.
- In [year], the incidence of [disease name] was estimated to be [number or range] cases per 100,000 individuals in [location].
Age
- Relapsing polychondritis is more commonly observed among patients of 40 and 60 years old but it can occur in childhood.[2][3]
Gender
- Relapsing polychondritis affects men and women equally.
Race
- There is no racial predilection for [disease name].
- [Disease name] usually affects individuals of the [race 1] race.
- [Race 2] individuals are less likely to develop [disease name].
Risk Factors
Natural History, Complications and Prognosis
Diagnosis
Diagnostic Criteria
Symptoms
- Decreased joint mobility
- Joint erythema
- Joint inflammation
- Joint swelling
- Pain on movement of joint
Physical Examination
All cartilage areas can be affected, though in many cases the disease will affect several areas where cartilage is found in the body, and leave others entirely alone. Parts of the body with cartilage, and therefore potentially affected by polychondritis, include the ears, nose, throat, heart valves and of course all areas where musculo-skeletal tissues are connected by cartilage. Specific resultant conditions may include Type 3 Tracheomalacia and Vasculitis.
Laboratory Findings
- There are no specific laboratory findings associated with relapsing polychondritis.
- Abnormal laboratory findings consistent with the diagnosis of relapsing polychondritis include:
- CBC with differentials
- Low hemoglobin
- Leukocytosis
- Eosinophilia
- ESR and CRP are usually raised
- Antibody testing
- Urinary glycosaminoglycans levels may be elevated[7]
- Urinary collagen type II neoepitope levels is elevated in active inflammation.[7]
- Levels of urinary collagen type II neoepitope is used to assess response to treatment.[8]
- Serum levels of cartilage oligomeric matrix protein is elevated and used as a marker of disease activity.[9]
- CBC with differentials

Treatment
Medical Therapy
Treatment plans typically involve suppression of the immune system with medicines, which often result in a side effect of increasing the risk of other infections.
