Vasculitic Neuropathy
=====================

Vasculitic neuropathy (VN) is a neurological disorder characterized by inflammation and damage to the nerves due to the presence of vasculitis, which is the inflammation of the blood vessels. This condition can affect various parts of the body, including the peripheral nervous system, causing symptoms such as pain, numbness, weakness, and loss of sensation.

Causes

Vasculitic neuropathy can be caused by several autoimmune disorders, infections, or drug reactions. The most common underlying conditions that lead to VN include:

1. Giant cell arteritis (temporal arteritis) - a form of vasculitis that primarily affects large and medium-sized arteries, usually in people over the age of 50.
2. Polyarteritis nodosa (PAN) - a type of vasculitis that mainly affects medium-sized arteries and veins.
3. Microscopic polyangiitis - a rare form of vasculitis that can involve small blood vessels throughout the body.
4. Granulomatosis with polyangiitis (Wegener's granulomatosis) - another rare type of vasculitis that primarily affects the sinuses, lungs, and kidneys, but can also involve the nerves.
5. Rheumatoid arthritis - an autoimmune disease that can cause inflammation and damage to joints, bones, and other tissues, including nerves.
6. Sjögren's syndrome - an autoimmune disorder that primarily affects the glands responsible for producing tears and saliva but can also lead to the development of vasculitis.
7. Infections, such as hepatitis C virus (HCV) and human immunodeficiency virus (HIV), can also cause vasculitis and subsequent neuropathy.
8. Certain medications, such as chemotherapy drugs, can cause a toxic effect on the nerves and lead to chemo neuropathy symptoms, which resemble those of VN.
9. Multiple myeloma (MMUS) peripheral neuropathy - a complication of multiple myeloma, a cancer of plasma cells, which can damage the nerves and lead to peripheral neuropathy symptoms.
10. Right ulnar neuropathy - a specific type of peripheral neuropathy that occurs when the ulnar nerve at the elbow becomes compressed or damaged, causing symptoms in the hand, such as pain, numbness, and weakness in the ring and pinky fingers.

Symptoms

The symptoms of vasculitic neuropathy depend on which nerves are affected and the severity of nerve damage. Common symptoms include:

1. Pain, burning sensations, or numbness in the affected area(s)
2. Weakness or difficulty moving certain muscles or muscle groups
3. Loss of sensation or altered sensitivity to touch, heat, or cold in affected areas
4. Loss of reflexes in the affected area(s)
5. Muscle cramps or spasms
6. Difficulty coordinating movements or fine motor skills
7. Hypersensitivity or intolerance to temperature changes
8. In severe cases, paralysis may occur if the motor nerves are severely damaged.

Diagnosis

The diagnosis of vasculitic neuropathy typically requires a combination of clinical evaluation, laboratory tests, and imaging studies. The following tests may be performed:

1. Blood tests to check for markers of inflammation or autoimmune diseases, as well as blood count and chemistry profile to assess overall health status.
2. Nerve conduction studies (NCS) and electromyography (EMG) - electrical tests to assess nerve function and conduction speed.
3. Magnetic resonance imaging (MRI) or computed tomography (CT) scans - to visualize the affected nerves and rule out other causes of symptoms such as tumors or injuries.
4. Biopsy - removal of a small tissue sample from an affected nerve or surrounding area for further analysis under a microscope to confirm the presence of vasculitis.
5. Angiogram - an invasive procedure where dye is injected into the blood vessels to create detailed images of blood flow and vessel walls. This test is not commonly used for diagnosing vasculitic neuropathy but may be ordered if there is suspicion of large vessel involvement or if other diagnostic tests are inconclusive.

Treatment

The treatment of vasculitic neuropathy involves addressing the underlying cause and managing symptoms. Treatment options may include:

1. Corticosteroids - anti-inflammatory medications that help reduce inflammation and ease symptoms associated with vasculitis and related autoimmune conditions.
2. Immune suppressants - drugs that inhibit the immune system's activity to prevent further damage to nerve tissue caused by ongoing inflammation. Examples include cyclophosphamide, azathioprine, mycophenolate mofetil, and rituximab.
3. Pain medication - over-the-counter or prescription painkillers to manage pain associated with vasculitic neuropathy.
4. Physical therapy - exercises designed to strengthen muscles affected by nerve damage and improve mobility and coordination abilities.
5. Antidepressants - medication used to treat depression but can also help manage pain associated with neuropathy in some patients. Examples include amitriptyline and nortriptyline.
6. Symptomatic treatments - ointments or creams for localized pain relief; capsaicin cream is an example of this type of treatment for neuropathy-related pain management.
7. Lifestyle modifications - quitting smoking, maintaining a balanced diet, staying active through exercise, managing stress levels, and avoiding alcohol consumption may help slow the progression of peripheral neuropathy in some patients.
