Relapsing polychondritis is a rare inflammatory disease characterized by autoimmune damage to cartilaginous tissue of various localizations, which can lead to its destruction and deformation. The disease mainly manifests itself in the form of recurring episodes of pain syndrome and hyperemia in the areas of the nose, auricles, joints, and can also affect deeper structures, such as cartilaginous tissue of the bronchi and heart. This disease is often associated with disorders of other body systems and requires a comprehensive approach to diagnosis and treatment.
History of the disease and interesting historical facts
Relapsing polychondritis was first described in medical literature in the mid-20th century. In 1923, British physician Edgar Gardner documented clinical cases that were later classified as relapsing polychondritis. He noted similarities with other autoimmune processes, which prompted further research in this area. Interestingly, in the early 1980s, the disease became the subject of intensive clinical and pathological studies that helped elucidate the pathogenesis and the relationship with other diseases, such as systemic lupus erythematosus and Behcet's syndrome. In some cases, relapsing polychondritis is also associated with certain genetic markers, indicating a possible predisposition to this disease.
Epidemiology
The epidemiology of relapsing polychondritis is characterized by its rarity. According to available data, the incidence varies from 0.5 to 3.5 cases per 100,000 people per year. In most cases, the disease is diagnosed in young and middle-aged people, mainly in men, although a high incidence is also observed in women. According to studies, the peak incidence occurs in the age categories from 20 to 50 years. Climate and ethnicity may play a certain role in prevalence, since some peoples, such as the indigenous people of North America, demonstrate a higher incidence rate.
Genetic predisposition to this disease
Signs of genetic predisposition to relapsing polychondritis have been established as a result of genetic studies, in particular, they are associated with certain alleles of the HLA-DR4 gene. The studies indicate the presence of associations between relapsing polychondritis and mutations in genes responsible for the function of immune system cells. In particular, impaired regulatory and proapoptotic mechanisms lead to unjustified activation of immune cells, which provokes autoimmune processes against cartilage tissue. The results of genetic analysis can help in diagnosing and determining the prognosis of the disease.
Risk factors for the development of this disease
Risk factors for relapsing polychondritis can be roughly divided into a group of physical and chemical factors, as well as other potentially related aspects. These include:
- Infectious diseases: the presence of acute viral or bacterial infections that can initiate an immune response.
- Medication use: Certain medications, such as antibiotics and anti-inflammatory drugs, can trigger the onset of the disease.
- Environmental factors: increased environmental pollution and long-term exposure to harmful chemicals.
- Stressful situations: Physical or emotional stress can activate autoimmune reactions.
- Trauma and surgery: Physical damage to cartilage tissue can trigger an immune response.
Diagnosis of this disease
Diagnosis of relapsing polychondritis is based on a comprehensive analysis of clinical, radiological and laboratory information. The main symptoms of the disease include:
- Pain and swelling in the area of the cartilage of the nose and ears.
- Articular pain, which can affect large and small joints.
- Deformation of cartilage, leading to a change in the appearance of the auricle or nose.
- Shortness of breath if the airways are involved.
Laboratory tests may include a complete blood count for inflammatory markers (eg, erythrocyte sedimentation rate, C-reactive protein) and immunological tests for autoantibodies. Radiological tests, such as x-rays and CT scans, help visualize the affected cartilaginous structures. Differential diagnosis is essential to exclude other rachistoid and systemic diseases.
Treatment
Treatment of relapsing polychondritis requires an individual approach and may include both conservative and surgical methods. General treatment is aimed at reducing the activity of the inflammatory process and improving the patient's quality of life. Pharmacological treatment includes the use of corticosteroids, immunosuppressants (eg, methotrexate and azathioprine), and nonsteroidal anti-inflammatory drugs. In more severe cases with life-threatening complications, surgical intervention may be indicated to correct deformities. Additional treatments may include physical therapy and alternative approaches such as acupuncture, which can help reduce symptoms and improve the patient's condition.
List of medications used to treat this disease
Among the most frequently used medications are:
- Prednisolone (corticosteroid).
- Methotrexate (immunosuppressant)
- Azathioprine (immunosuppressant)
- Ibuprofen (NSAID)
- Naproxen (NSAID)
- Leflunomide (immunosuppressant)
Disease monitoring
Monitoring of relapsing polychondritis includes regular follow-up examinations to assess the dynamics of the disease and adjust the treatment strategy. The prognosis of the disease may vary: some patients live with minimal symptoms, while others may develop serious complications that affect the quality of life. There are cases of complete recovery, but in some cases, relapses and progression of the disease are observed, which requires constant monitoring and timely adjustment of treatment.
Age-related features of the disease
Age-related features of relapsing polychondritis vary. In young patients, the disease may be more acute and progress rapidly, while in older people, symptoms may also be pronounced, but in general, it often occurs with less pronounced relapses. In children, this disease is extremely rare, but its manifestations may be more specific and disguise themselves as other diseases.
