Chronic inflammatory demyelinating polyneuropathy (CIDP)

Chronic inflammatory demyelinating polyneuropathy (CIDP)

CIDP is a rare disease that affects people of all ages. It affects men twice as often as women, and the average age of onset is 50 years. The prevalence of pathology is approximately 5-7 cases per 100,000 people.

CIDP significantly reduces the patients’ quality of life and can lead to disability. Modern treatments help slow down the course of polyneuropathy, but do not repair damaged nerves. In addition, standard therapy is associated with the risk of developing numerous side effects. Therefore, an active search is currently underway for new, more effective and safe methods of treatment, and cell therapy is one of the most promising directions in this field.

Chronic inflammatory demyelinating polyneuropathy (CIDP): what is it in simple words?

CIDP is a rare neurological disease characterized by inflammation of nerve roots and peripheral nerve fibers. Normally, nerve fibers are covered with a protective fatty sheath – myelin, which allows them to quickly transmit signals (40-60 meters per second).

Sometimes, for unknown reasons, the immune system mistakenly starts attacking healthy cells in the body. In CIDP, it attacks the myelin sheath. Damage to myelin slows or blocks the transmission of nerve impulses, causing the patient to experience symptoms such as weakness, paralysis, or impaired motor function.

Why is demyelinating polyneuropathy dangerous?

Хроническая восплаительная демиелинизирующая нейропатия

If CIDP is not diagnosed and treated in time, the disease can lead to dangerous health consequences:

  • Disruption of nerve signal transmission. Damage to myelin leads to blockage or slowing down of nerve impulses. This, in turn, causes impairment of sensory and motor functions.
  • Pain syndrome. Patients with demyelinating polyneuropathy often experience severe pain in the area of the affected nerves. This negatively affects the ability to perform daily tasks.
  • Muscle weakness and paralysis. The progressive destruction of the myelin sheath leads to muscle atrophy due to insufficient nerve stimulation, which can lead to loss of muscle function, up to paralysis.
  • Loss of independence. In the absence of treatment of the disease, many patients lose the ability to move and take care of themselves.

Pain and impaired motor functions significantly reduce the quality of life of patients, limiting their activity, as well as the ability to work and participate in social life. Therefore, it is important that treatment be started as early as possible.

What is not recommended for people with demyelinating polyneuropathy?

With CIDP, doctors recommend avoiding:

  • Self-medication. Incorrect therapy can not only not help to cope with the symptoms of polyneuropathy, but also aggravate its course. Therefore, patients should adhere to the recommendations of a qualified neurologist.
  • Excessive physical stress. Patients with CIDP should avoid excessive exercise, which can increase muscle weakness and worsen the condition.
  • Sitting or standing for a long period of time. In demyelinating polyneuropathy, it is important to avoid prolonged periods of immobility. The deterioration of the blood supply to the muscles negatively affects their function.
  • Smoking and drinking alcohol. These bad habits have a negative effect on the nervous system and can aggravate the course of polyneuropathy.

In addition, doctors advise not to ignore symptoms of the disease, such as pain, numbness, loss of sensation or impaired motor functions, as they may indicate the progression of the disease.

Causes of demyelinating polyneuropathy

The exact causes of CIDP are unknown, although there is strong evidence that it is an autoimmune disease. It occurs due to a malfunction of the immune system, in which it begins to attack healthy cells in the body. Why exactly this failure occurs is still not exactly clear.

Recently, scientists have identified antibodies directed against peripheral nerve components that cause rare variants of CIDP. These data are encouraging that antibodies causing other forms of demyelinating polyneuropathy will soon be identified.

Symptoms of demyelinating polyneuropathy

Symptoms of the disease vary depending on the location of the nerves and the degree of their damage. The most common manifestations of the disease are:

  • numbness and tingling (especially noticeable in the arms and legs);
  • muscle weakness (difficulty lifting objects, walking, and performing daily tasks);
  • impaired coordination of movements;
  • pain (widespread or concentrated along the affected nerves, the pain may be sharp, throbbing or aching);
  • loss of sensation in certain areas of the body;
  • fine motor impairment;
  • impaired or lost reflexes;
  • problems with urinary or bowel control;
  • decreased temperature sensitivity;
  • fast fatigability.

The symptoms listed above are a signal to see a doctor. They do not necessarily indicate the development of CIDP, but the patient requires a thorough diagnostic examination. Call or write to the medical coordinator of MedTour, who will select an affordable clinic and a neurologist for you to diagnose polyneuropathy.

What tests should be done in case of polyneuropathy?

When CIDP is suspected, doctors usually order the following laboratory tests:

  • a general blood and urine test (to detect an inflammatory process or infection that may be associated with the development of polyneuropathy);
  • a blood test for antibodies (the presence of specific antibodies may indicate the development of an autoimmune process);
  • analysis for the level of vitamins and minerals.

Sometimes doctors additionally recommend testing for metabolic markers, inflammatory markers, and toxins.

Diagnosis of demyelinating polyneuropathy

Хроническая восплаительная демиелинизирующая нейропатия

A comprehensive examination for the diagnosis of CIDP, as a rule, includes the following medical tests:

  • electroneuromyography;
  • lumbar puncture and analysis of cerebrospinal fluid for protein and inflammatory markers;
  • magnetic resonance imaging to evaluate the nerve roots and look for signs of inflammation.

Because CIDP is rare, it should be diagnosed by an experienced physician. Call by phone or fill out the feedback form. The medical coordinator of MedTour will select for you a neurologist specializing in the treatment of polyneuropathy free of charge.

Treatment of demyelinating polyneuropathy

Хроническая восплаительная демиелинизирующая нейропатия

The main goals of CIDP therapy are to stop pathological immune processes, reduce inflammation, and prevent further damage to the myelin sheath and nerve damage. Most often, doctors prescribe corticosteroids, intravenous immunoglobulins, and plasmapheresis to achieve these goals.

According to studies, all three methods of therapy have approximately the same level of effectiveness. The choice of technique depends on its availability (for example, plasmapheresis can not be done in all medical institutions), tolerability of treatment by patients and the presence of side effects. To avoid disability, therapy should be started as early as possible.

Treatment is considered successful if the patient after a course of therapy shows a marked improvement in motor skills, sensitivity and ability to perform daily activities.

Stem cell treatment

Today, doctors use various methods of immunosuppressive (suppressing the immune system) therapy to treat CIDP. However, such drugs do not always achieve long-term, drug-free and asymptomatic remission. Some patients after standard therapy for CIDP still experience relapses, sometimes even leading to disability and death.

Therefore, scientists are actively looking for new, safer and more effective therapeutic approaches. One of them is hematopoietic stem cell transplantation (HSCT). These are progenitor cells that give rise to various types of blood cells. The main advantage of these stem cells is that they can be obtained from the patient’s own bone marrow or peripheral blood without resorting to the use of donor material.

HSCT is widely used to treat refractory (hard-to-treat) autoimmune diseases to kill autoreactive immune cells and restore immune system self-tolerance, a normal state in which the immune system does not attack healthy cells in the body.

Hematopoietic stem cells have the ability to regulate the immune system. Currently, HSC transplantation is actively used for intractable patients with chronic demyelinating inflammatory polyneuropathy.

How do stem cells help with CIDP?

According to research, hematopoietic stem cell therapy helps:

  • achieve immune remission without drug treatment (in 83% of cases);
  • improve unaided movement (from 33% to 86%);
  • increase the average grip strength of the right/left hand (from 18.1/16.5 kg to 30.8/29.1 kg);
  • increase the average speed of nerve conduction (from 27.2 m/s to 38.3 m/s);
  • increase the total motor potential (from 3.6 mV to 4.1 mV).

Specialists assessed the condition of patients for 5 years. Every year after HSCT, the performance improved. The data above are from the fifth year after stem cell transplantation.

In general, cell therapy helps to relieve symptoms, improve neurologic assessment results, and achieve a long period of remission in most patients.

What do the studies say?

From 2002 to 2018, about 70 cases of chronic inflammatory demyelinating polyneuropathy were reported worldwide, which were completely cured with hematopoietic stem cell transplantation.

According to general estimates, the frequency of relapses in patients decreased to varying degrees. The results of the electrophysiological study have improved significantly. Symptoms improved, disease progress was effectively controlled, and some patients were able to completely stop taking immunosuppressants after HSCT.

Currently, studies of the effectiveness of stem cell therapy for CIDP are ongoing, and the interim results prove the great potential of this therapeutic technique.

One of MedTour’s goals is to make innovative treatments more accessible to patients. Currently, we are collaborating with a number of clinics around the world that offer the possibility of CIDP therapy with hematopoietic stem cells.

Prevention of demyelinating polyneuropathy

There are no methods that can prevent the failure of the immune system that leads to the development of CIDP. However, patients should be aware that early diagnosis and qualified treatment help to avoid further progression of the disease and disability. Therefore, knowledge of the symptoms of demyelinating polyneuropathy and access to modern therapeutic techniques are the key to the successful treatment of this disease.

What vitamins are needed for demyelinating polyneuropathy?

Хроническая восплаительная демиелинизирующая нейропатия

Some vitamins play an important role in maintaining the health of the nervous system. However, it is important to consider that any vitamin complexes should be prescribed by a doctor after a comprehensive diagnostic assessment of the patient’s condition. For the prevention of neurological disorders, the following vitamins are used:

  • Vitamin B12. A lack of this vitamin can lead to nerve demyelination and other neurological problems.
  • Vitamin B6 (pyridoxine). It is involved in the formation of myelin and the maintenance of the nervous system.
  • Vitamin B1 (thiamine) and vitamin B9 (folic acid). They are important for the normal functioning of the nervous system as a whole.
  • Vitamin E. This antioxidant helps protect nerve cells from damage and inflammation.
  • Vitamin D. Adequate levels of vitamin D contribute to the health of the nervous and immune systems.
  • Magnesium. It is involved in the transmission of nerve impulses and the maintenance of normal muscle function.

Do not forget that self-medication and excessive use of vitamins can be harmful to health. Be sure to check with your doctor before taking vitamin supplements.

What drugs are taken for chronic polyneuropathy?

Treatment for CIDP depends on the type and severity of the disease. Typically, doctors prescribe corticosteroids, immunomodulators, intravenous immunoglobulin injections, pain relievers, nerve conduction drugs, and other drugs to reduce symptoms and improve the quality of life of patients. It is important to consider that only an experienced doctor can plan an effective treatment protocol.
