Neurodermatitis

Neurodermatitis

Neurodermatitis is a chronic skin disease of a neurogenic-allergic type that occurs with periods of remission and exacerbation.

In medical terminology, the term "neurodermatitis" was first used in 1891. At that time, this name characterized a pathological process, accompanied by primary skin itching and scratching.

At present, a neurodermatitis is a disease that accounts for approximately 40% of the total number of all skin lesions.

Most often it is detected in childhood, but in the pubertal period (puberty period), in the absence of other pathologies, disappears independently. Nevertheless, parents should be very careful, since in the absence of adequate treatment of neurodermatitis, complications can develop (changes in skin relief, formation of seals, and likelihood of infection).

As a preventive measure of neurodermatitis in childhood, experts recommend to adhere to the rules of general hygiene and breastfeeding regimen. However, to prevent the development of the pathological process in adults, one should observe professional and mental (psychological) hygiene.



The causes of the onset and development of neurodermatitis

  1. Hereditary predisposition.
  2. Stresses, nervous disorders and prolonged negative emotions.
  3. Harmful production factors.
  4. Long-term mental stress and heavy physical labor.
  5. Pathology of the digestive system.
  6. Systematic violation of the regime of the day.
  7. Nutritional, medicinal and other types of intoxication.
  8. Environmental factors provoking the development of allergic reactions (dry food for aquarium fish, animal wool, woolen things, house dust, some cosmetics, feather pillow and blanket filler, flower pollen, food preservatives and some food products).
  9. Medications.

Only after the cause of neurodermatitis has been elucidated can one begin to treat the disease.

Types of neurodermatitis

Neurodermatitis is a disease that has several types that determine the degree of prevalence of the pathological process in the patient's skin.

Restricted neurodermatitis

With the development of the focal form of neurodermatitis, patients complain of skin rashes in a limited space. As a rule, in this case, plaques consisting of small papular formations are localized in the neck region, on the back of the knees, as well as in the ulnar fossa, in the anus and genital area. Most often these plaques are arranged symmetrically and have a regular oval shape. Their color can range from pink to brown. In the affected foci the skin is dry, infiltrated, with characteristic lichenification (skin pattern). The peripheral part of the affected focus is pigmented. It gradually transforms into healthy, unchanged skin. In the center of the focus during the examination, you can identify a zone that consists of papules the size of a pinhead (or slightly more). Papules have a shiny surface and irregular contours.

With focal neurodermatitis (as with other forms of it) there is no mocculation. Pathological foci, as a rule, are covered with hemorrhagic crusts or gray-white scales. After their falling off, there are hyper- or depigmented spots. During the development of the disease, patients complain of itching, which is aggravated by irritating factors, and also at night.

Diffuse neurodermatitis

Diffuse neurodermatitis, or, as it is also called by clinicians, atopic dermatitis , is a more severe form of pathology, which is characterized by the emergence of multiple lesions. As a rule, they are localized on the upper and lower extremities (in popliteal cavities and ulnar folds), as well as on the trunk. However, diffuse neurodermatitis often affects the neck, genitals, anus and face. In this case, lesions are fused, lichenified and infiltrated skin areas. In some places, apart from lichenification, flat, shiny nodules arise. Sometimes in patients after scratching there is a brief mopping. As a consequence, lesions can become infected, complicated by lymphadenitis or pyoderma. Patients suffering from diffuse neurodermatitis are characterized by puffiness and hyperemia of the skin, often covered with small scales.

In the case when the disease develops in childhood, lesions can also occur on the scalp and around the eyes. During puberty, the pathological manifestations of children often subsided.

Hypertrophic neurodermatitis

Neuromuscular Ermann is a rare form of pathology, in which the lesions are localized on the inner surface of the thighs and in the groin-femoral folds. In this case, patients have a pronounced infiltration and lichenification of the skin, and severe itching, which has a paroxysmal character. Often, the pathological process is accompanied by the emergence of warty-like formations (warty neuroidermis of Kreibich).

Linear neurodermatitis

This pathology, in which the lesions are localized mainly on the extensor surfaces of the hands and feet and have the shape of bands, sometimes with a warty or scaly surface.

Acute follicular neurodermite

With the development of this form of the disease, the papules are located along the mouths of the hair follicles and have a pointed shape.

Depigmented neurodermite

This form of the disease is characterized by the appearance in the affected areas of pronounced depigmentation (partial or complete loss of pigment by tissues).

Decalculating neurodermatitis

As a rule, the pathological process affects areas of the body covered with gun hair, and is accompanied by their loss.

Psoriasiform neurodermatitis

In this case, lesions are red seals covered with small silver-white scales. Most often they are localized on the head and on the neck.

Symptoms of neurodermatitis

Neurodermatitis symptoms

Neurodermatitis symptoms

The most typical signs of the disease include itching, rash, peeling, redness of the skin and neurotic disorders. The most characteristic symptom of neurodermatitis is the occurrence of severe itching before the appearance of rashes. Further on the skin gradually form small skin nodules with a shiny surface. Initially, they do not differ in color from normal skin, and then acquire a brownish-pink coloration. After some time, the nodular formations begin to merge, forming a continuous, scaly or hemorrhagic crust with a fuzzy border. The affected area of ​​the skin becomes bluish or crimson. At the same time, depigmented areas are often observed in old foci.

It should be emphasized that with neurodermatitis the area of ​​the pathological process differs and depends on its variety. Most lesions are localized in the groin, a fold between the buttocks, in the scrotum, on the large labia, in the popliteal and ulnar folds, and also on the neck. With the development of the disease, there is a significant decrease in the function of the adrenal glands, in connection with which the skin of the patient darkens. However, patients often lose body weight, which has a very negative effect on the general condition of their body. There is also a decrease in blood pressure, complaints of rapid fatigue, weakness, apathy and increased nervous excitability. When performing diagnostic laboratory tests, there is a decrease in blood glucose and a decrease in the secretion of gastric juice.

In some cases, neurodermatitis can lead to the development of lymphadenitis (inflammation of the lymph nodes), and this, in turn, leads to a deterioration in the work of many organs.

As a rule, relapses of the disease occur in the cold season, and in the summer, patients, on the contrary, have significant improvements in their health status.

It should be noted that the most affected people are those in whom the lesions are localized on their hands. This is due to the fact that hands are most likely to be affected by moisture and mechanical influences, aggravating the course of the pathological process.

Diagnosis of neurodermatitis

First of all, when diagnosing different types of neurodermatitis differentiate from prurigo, red flat lichen, chronic eczema, mushroom mycosis, lymphatic erythroderma, vulva vulgaris, etc.

Also, the data of anamnesis (including family history) are necessarily taken into account. The patient undergoes a visual examination, he is taken a blood test (to determine the level of immunoglobulin E in the serum) and samples from the affected area (in the presence of pustules, bacapsis is always performed on the microflora). It should be noted that in people with neurodermatitis, the level of immunoglobulins of class E in the blood serum is increased, as well as in such patients there are significant defects in cellular immunity, there is a decrease in the number of T-lymphocytes, and in the peripheral blood an increased number of eosinophils is detected.

Treatment of neurodermatitis

The tactics of treatment for neurodermatitis is aimed at eliminating the disorders that triggered the development of the pathological process, as well as preventing recurrence and prolonging remissions.

General therapeutic measures

  1. A strict diet that provides for a complete limitation of marinades, spices, chocolate, spicy and smoked foods, citrus fruits, cocoa, whole cow's milk, eggs, strong meat broths, etc.
  2. Prohibition of finding pets, aquarium fish and flowering plants in a residential area (especially if sensitization is detected).
  3. Daily carrying out of wet cleaning, and also refusal of carpets in which dust mites can be.
  4. If possible, the clothing of a patient suffering from a neurodermitis should be spacious in order to avoid possible friction and pressure. Synthetic and woolen things in this situation are contraindicated.
  5. A prerequisite for the patient: a full sleep, the complete elimination of fatigue and stressful situations.
  6. Restriction of water procedures.

The use of sedative and psychotropic drugs

In order to reduce the likelihood of developing neurotic reactions, patients are shown the use of psychotropic and sedative drugs, tranquilizers and antidepressants. I would like to emphasize that from plant remedies experts recommend using a tincture of valerian root or tincture of a peony.

Sanitation of foci of chronic infection

This is one of the most important conditions that must be observed during the comprehensive treatment of neurodermatitis.

Normalization of the gastrointestinal tract

In the event that a patient suffering from a neurodermatitis is found to have a dysfunction of the digestive system, during the treatment he is shown taking enzyme preparations (mezim forte, festal, digestal, pancreatin, etc.). Probiotics are prescribed for dysbacteriosis of the intestine, and for severe chronic forms of neurodermatitis, hepatoprotectors.

Systemic drugs used in the treatment of neurodermatitis

The main role in the treatment of this pathology is played by antihistamines (N-histamine blockers).

The first generation of drugs include chloropyramine, mebhydroline, chlorpheniramine, promethazine, diphenhydramine.

Terfenadine, astemizole and fexofenadine are second-generation drugs.

The group of drugs of the third generation includes ebastin, cetirizine and loratadine.

At the same time, in the treatment of neurodermatitis, patients are shown the administration of ketotifen (a stabilizer of mast cell membranes) and cyproheptadine (a blocker of histamine receptors with antiserotonin activity).

At the moment, the most popular drugs are second and third generation, which have a prolonged effect and have no side effects on the central nervous system (violation of the speed of reaction and coordination of movements, drowsiness, inhibition, etc.).

When the pathological process worsens, patients are shown intravenous administration of 10% calcium gluconate solution or 30% sodium thiosulfate. In the event that a secondary bacterial infection is attached to the acute form of neurodermatitis and furunculosis develops, antibiotic therapy with broad-spectrum antibiotics is prescribed to patients.

In especially severe cases, when the general condition is violated and there is a pronounced exudation for a short time and with great care, hormone therapy is prescribed.

At the same time, not so long ago, immune preparations stimulating T-lymphocytes (levamisole, thymalin, thymogen, t-activin) began to be used in complex therapy of neurodermatitis, and myelopid was used to support B-cell immunity. Also, many specialists and patients respond well about cyclosporine. This immunosuppressor, which is indicated for the treatment of very severe forms of neurodermatitis, which can not be treated with traditional drugs.

Also, without fail, during the treatment the patient is given vitamin therapy with vitamins A, B and E.

Drugs for topical treatment of neurodermatitis

For local treatment of neurodermatitis, various lotions (boric, resorcinic, tannic) are used in dermatological practice, as well as pastes with tar, ichthyol, naphthalane, etc. In severe cases, unhalogenated corticosteroid ointments of prolonged action are superimposed on the affected areas of the skin that do not cause atrophy and thinning Skin integument. These drugs have a minimum of side effects, and therefore they are allowed to use even when treating young children.

Physiotherapy treatment

Very well recommended in the treatment of neurodermatitis is a procedure such as light therapy (using a quartz lamp, UV or selective phototherapy). Selective phototherapy, involving the use of UV rays with a wavelength of 315-320 nm is indicated for patients suffering from the neurodermitis, only during the remission of the disease. The duration of the course of treatment is 15-20 procedures.

Also, as a physiotherapeutic treatment for neurodermatitis, dermatologists recommend cryomassage (the use of liquid nitrogen) and irradiation of lesions by a medical laser.

At the same time, sanatorium-and-spa treatment (the coast of the Black and the Dead Seas) is very beneficial for the patient's organism.

Extracorporeal hemocorrection

This is a procedure that involves the treatment of components of the patient's blood plasma, or the removal of harmful products from it, which trigger the development of the pathological process.

Prophylaxis of neurodermatitis

In order to prevent the development of neurodermatitis, experts recommend the timely treatment of childhood eczema and atopic diathesis, as well as constantly maintain normal physical and mental well-being. Skin covers must be constantly protected from overheating or hypothermia, exposure to corrosive substances and other irritants. However, people prone to the development of allergic reactions are recommended to exclude from their diet foods that can trigger the development and exacerbation of the pathological process, as well as limit the intake of carbohydrates and salt.
