Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare autoimmune disorder in which there is swelling of nerve roots and destruction of the covering (myelin sheath) over the nerves. This causes weakness, paralysis, and/or impairment in motor function, especially of the arms and legs. Sensory loss may also be present, causing numbness, tingling, and burning sensations. The motor and sensory impairments are usually found on both sides of the body. The severity of CIDP can vary from mild to severe. CIDP can affect any age group, and the onset may begin anytime throughout life.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a neurological disorder that causes progressive weakness and impaired sensory function in the legs and arms. Symptoms often include tingling or numbness (first in the toes and fingers), weakness of the arms and legs, loss of deep tendon reflexes, fatigue, and abnormal sensations.[1] Other symptoms may include pain, difficulty swallowing (dysphagia), and double vision (diplopia).[2] CIDP is thought to be caused by the immune system mistakenly attacking and damaging the myelin sheath (protective cover of nerve fibers) of the peripheral nerves.[3] CIDP is closely related to Guillain-Barre syndrome (GBS) and is considered the “chronic counterpart” of GBS. Treatment may include corticosteroids, immunosuppressant drugs, plasma exchange, physical therapy, and/or intravenous immunoglobulin (IVIG) therapy.[1] Left untreated, 30% of people with CIDP will progress to wheelchair dependence.[4]

Types of CIDP

CIDP can come in different forms:

  1. Classic CIDP: This is the most common type and affects both sensory and motor nerves. It progresses over time.
  2. Multifocal Motor Neuropathy (MMN): Unlike classic CIDP, MMN primarily affects motor nerves, leading to muscle weakness. It usually doesn’t progress as much.
  3. Distal Acquired Demyelinating Symmetric (DADS): This type affects the nerves in a symmetrical pattern, usually starting in the hands and feet.

Causes of CIDP

We don’t always know why someone gets CIDP, but there are some potential triggers:

  1. Autoimmune Response: CIDP may occur when your immune system mistakenly attacks the protective covering of your nerves, called myelin.
  2. Infections: Certain infections, like the Epstein-Barr virus, can trigger CIDP in some cases.
  3. Genetic Factors: Although rare, there might be a genetic predisposition for some people to develop CIDP.
  4. Environmental Factors: Exposure to certain chemicals or toxins may play a role in CIDP development.
  5. Unknown: In many cases, the cause remains unknown, which can be frustrating.

Symptoms of CIDP

CIDP can manifest in various ways, but common symptoms include:

  1. Weakness: You might notice muscle weakness, often starting in the legs.
  2. Tingling and Numbness: You could experience a tingling or numbness sensation in your hands and feet.
  3. Loss of Balance: Difficulty maintaining balance or coordination can occur.
  4. Fatigue: Feeling tired is a common symptom, as CIDP can be draining.
  5. Pain: Some people with CIDP experience pain, which can vary from mild to severe.
  6. Difficulty Walking: Weakness in the legs can make walking challenging.
  7. Deterioration: Symptoms might worsen over time if not treated.

Diagnostic Tests for CIDP

If you or your doctor suspect CIDP, several tests can help confirm the diagnosis:

  1. Electromyography (EMG): This test measures the electrical activity in your muscles and can identify nerve damage.
  2. Nerve Conduction Studies: These measure how quickly electrical impulses travel through your nerves.
  3. Lumbar Puncture (Spinal Tap): A sample of cerebrospinal fluid can show signs of inflammation.
  4. MRI: Magnetic resonance imaging can reveal nerve damage or abnormalities.
  5. Blood Tests: These can rule out other conditions with similar symptoms.

Treating CIDP

The good news is that CIDP can often be managed effectively. Treatment options include:

  1. Intravenous Immunoglobulin (IVIG): This therapy involves injecting antibodies to help regulate the immune response.
  2. Corticosteroids: Medications like prednisone can reduce inflammation and control symptoms.
  3. Plasma Exchange (Plasmapheresis): This procedure removes harmful antibodies from your blood.
  4. Immunosuppressive Drugs: Medications like azathioprine can suppress the immune system to prevent further damage.
  5. Physical Therapy: Exercises and stretches can help improve muscle strength and mobility.
  6. Pain Management: Medications or alternative therapies can address pain.
  7. Supportive Devices: Mobility aids like canes or braces can assist with walking.

CIDP Drugs

Several drugs are commonly used to manage CIDP:

  1. IVIG Products: Privigen, Gammagard, and Octagam are some brands of intravenous immunoglobulin.
  2. Corticosteroids: Prednisone is a common choice.
  3. Azathioprine: An immunosuppressive drug that can help manage CIDP.
  4. Mycophenolate Mofetil: Another immunosuppressive medication.
  5. Plasma Exchange: While not a drug, it’s a significant treatment option for CIDP.

In conclusion, CIDP is a complex condition affecting the nervous system, but it can be managed with proper medical care. Understanding its types, causes, symptoms, diagnostic tests, treatments, and drugs can empower you to work with your healthcare team to find the best approach for your specific situation. Remember, you’re not alone, and there is hope for managing CIDP and improving your quality of life.
