relapsing polychondritis

Relapsing polychondritis (RP) is a rare autoimmune connective tissue disorder characterized by episodes of painful, destructive inflammation of the cartilage [3]. This condition tends to occur in episodes or flares, which can last for days or weeks and may recur repeatedly over years [1].

The first symptoms of RP are usually pain, tenderness, swelling, and redness in one or both ears [1]. The disease primarily affects the cartilage of the ear and nose but can also involve other areas such as the eyes, tracheobronchial tree, heart valves, kidneys, joints, skin, and blood vessels [12].

RP is a severe, episodic, and progressive inflammatory condition involving cartilaginous structures [5]. The disease is characterized by recurrent inflammation of the cartilage in the body, which can lead to deterioration of the cartilage [4].

The symptoms of RP can vary from person to person but often include:

• Painful joints
• Changes in the ears or nose (such as redness, swelling, and tenderness)
• Inflammation of other areas such as the eyes, tracheobronchial tree, heart valves, kidneys, skin, and blood vessels

RP is a rare disease that affects cartilage in parts of the body, usually affecting ears, nose, throat & lungs [9]. It is a multisystem disease involving cartilaginous and proteoglycan-rich structures [13].

The diagnosis of RP is mainly suggested by the presence of flares of inflammation of the cartilage, particularly in the ears, nose or respiratory tract, and more rarely, in the presence of other manifestations [13].

Relapsing polychondritis (RP) is a rare autoimmune disorder that causes recurrent inflammation of cartilage, leading to various symptoms. Here are the common signs and symptoms of RP:

• Ear involvement: One or both ears become red, swollen, and very painful, often with no prior trauma or infection [6][8]. The earlobe is not typically affected.
• Cartilage pain and swelling: Sudden pain and tenderness in cartilage, often accompanied by redness and swelling [4][14].
• Joint inflammation: Joint pain similar to arthritis, which can be a symptom of RP [1][5].
• Eye problems: Redness and pain in the eyes are common symptoms of RP [9].
• Saddle nose deformity: Cartilage collapse at the bridge of the nose, leading to a saddle-shaped deformity [1].
• Respiratory tract chondritis: Inflammation of the airways can cause shortness of breath, wheezing, and other respiratory symptoms [5][12].
• Unexplained arthritis: Joint pain and inflammation without any underlying cause or trauma [13].
• Auditory or vestibular dysfunction: Hearing problems or balance issues can occur due to RP's impact on cartilage in the ears [12].

These symptoms often occur in episodic flares, causing redness, swelling, pain, and other discomforts based on the organ or tissues affected. Early recognition of these signs and symptoms is crucial for timely treatment and limiting permanent damage.

Diagnostic Tests for Relapsing Polychondritis

Relapsing polychondritis (RPC) is a rare autoimmune disorder that can be challenging to diagnose due to its variable presentation and lack of specific diagnostic tests. However, several diagnostic tests can help establish the diagnosis.

• Clinical Features: The diagnosis of RPC is primarily based on a combination of clinical features, radiographic findings, and biopsy of an inflamed tissue [9]. A healthcare provider can diagnose the condition if you have at least three associated symptoms over time [2].
• Laboratory Tests: While laboratory tests are not specific for RPC, they can help exclude other disorders. Blood tests, such as the erythrocyte sedimentation rate (ESR), can detect evidence of inflammation [6]. Synovial fluid analysis reveals no or mild inflammatory changes [11].
• Imaging Studies: Imaging studies, including MRI and CT scans, can be useful in diagnosing RPC. MRI has been a useful adjunct in the clinical diagnosis of relapsing polychondritis, particularly in distinguishing between edema, fibrosis, and other conditions [4]. Dynamic chest CT during inspiration and expiration can assess respiratory tract involvement [5].
• Biopsy: Biopsy of an inflamed tissue can provide a definitive diagnosis of RPC. However, this is not always necessary or practical.

Key Points

• No single blood or imaging test can be used to diagnose RPC.
• The diagnosis is generally based on the detection of a combination of clinical features, radiographic findings, and biopsy of an inflamed tissue.
• Laboratory tests are not specific for RPC but can help exclude other disorders.
• Imaging studies, including MRI and CT scans, can be useful in diagnosing RPC.

Relapsing polychondritis (RP) is a rare autoimmune disorder that requires effective management to alleviate symptoms and prevent complications. While there is no cure for RP, various drug treatments can help control the condition.

Commonly Used Medications:

• Corticosteroids: These are often used as first-line treatment to reduce inflammation and swelling. Examples include prednisone and cortisone.
• Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs, such as ibuprofen and naproxen, can help alleviate pain and reduce inflammation.
• Colchicine: This medication is sometimes used to treat mild cases of RP or as an adjunct therapy to other treatments.

Immunosuppressive Medications:

• Methotrexate (MTX): MTX has been shown to be effective in treating RP, although its efficacy may vary from person to person.
• Cyclophosphamide: This medication is sometimes used as a last resort for severe cases of RP that have not responded to other treatments.

Biologic Agents:

• Tumor necrosis factor-alpha (TNF-α) inhibitors: These medications, such as infliximab and adalimumab, can be effective in treating RP by targeting the underlying inflammation.
• Abatacept: This medication has been used in some cases to treat RP, although its efficacy is not well established.

Other Medications:

• Azathioprine: This immunosuppressive medication may be used in some cases of RP that have not responded to other treatments.
• Rituximab: This medication has been used in some cases to treat RP, particularly when other treatments have failed.

It is essential to note that the effectiveness and safety of these medications can vary from person to person. A healthcare professional should be consulted to determine the best course of treatment for an individual with relapsing polychondritis.

Relapsing polychondritis (RP) is a rare and complex inflammatory condition that can be challenging to diagnose due to its variable presentation. As such, it's essential to consider the differential diagnoses for RP.

Key Differential Diagnoses:

• Granulomatosis with polyangiitis: This is a type of vasculitis that affects small- and medium-sized blood vessels, leading to inflammation and damage to various organs.
• Eosinophilic granulomatosis with polyangiitis: Also known as Churg-Strauss syndrome, this condition involves the presence of eosinophils in the blood and tissues, leading to inflammation and damage to various organs.
• Behçet disease: This is a rare disorder characterized by inflammation of the blood vessels, which can lead to symptoms such as mouth sores, genital ulcers, and eye problems.
• Leprosy: Also known as Hansen's disease, this is a chronic bacterial infection that primarily affects the skin, nerves, and eyes.

Other Differential Diagnoses:

• VEXAS syndrome: This is a rare genetic disorder characterized by inflammation of various organs, including the cartilage, due to mutations in the ADAR1 gene.
• Myelodysplastic syndromes: These are a group of disorders that affect the production of blood cells, leading to anemia, infections, and bleeding problems.

Key Points:

• The differential diagnosis for RP is broad and includes various conditions that can mimic its symptoms.
• A thorough medical history, physical examination, laboratory tests, and imaging studies are essential in differentiating RP from other conditions.
• Early recognition and treatment of RP can improve outcomes and prevent complications.
