Causes of the itching with psoriasis

Itching of the skin is always a consequence of any malfunctions inside the body - for example, intoxication. Thus the patient can feel, both easy unpleasant sensation, and a strong burning sensation.

The reasons for this condition can be:

  • infection of the external inflammatory process;
  • improper use of cosmetics, or use of unsuitable cosmetics;
  • taking certain medications (often in the form of self-medication);
  • adherence of endocrine diseases;
  • nervous disorders;
  • disturbances in metabolic processes;
  • liver disease;
  • allergic reactions.

It is unlikely that the patient will be able to establish the cause of itching in psoriasis. To do this, you need to see a doctor and go through a series of special studies.

Risk factors

  • at progression of pathological process (for example, at relapse);
  • when using non-conforming medicines;
  • with general chronic or acute poisoning;
  • when exposed to a psychogenic factor;
  • when attaching scabies or allergies;
  • in the HIV-associated process;
  • after eating some products;
  • after contact with chemicals;
  • under harmful production conditions;
  • with a sharp change in climate;
  • diseases of the digestive system;

Pathogenesis

The itching sensation is a neuro-reflex process. In pathogenesis, a special role is played by disorders of the cerebral cortex function and neurophysiological factors.

In patients with an easily excitable nervous system, pruritus may appear on the skin in the region of an earlier inflammatory process. Unpleasant sensations can be amplified if, in addition, the patient suffers from an endocrine or cardiovascular system.

Itching in psoriasis can be primary (for metabolic disorders, for visceropathies, etc.) and secondary (due to changes in the structure of the skin in the affected areas).

Epidemiology

According to statistics, about 4% of the world's population is affected by psoriasis. In this case, itching occurs in 80% of patients with psoriasis of the skin. This itch can have a different intensity.

Approximately in 20% of patients there is no sensation of itching at all, which at first can make it difficult to diagnose the disease.

Symptoms

Itching is usually attributed to the classic symptoms of psoriasis, despite the fact that it is not present in all patients.

Itching usually occurs with the onset of the stage of exacerbation of the disease, when an acute inflammatory process begins with the appearance of convex elements on the skin - reddish patches with a dense scaly surface. Most often such plaques cover the folds of elbows, knees, phalanges of fingers.

As additional symptoms, you can name:

  • cracks and small bleeding in places of plaque damage;
  • deterioration of the nail plates, appearance of dimples on them, color spots, stratification;
  • spots and itching in the skin folds (for example, under the buttocks or under the mammary glands).

The first signs in the form of itching and burning can appear even before the detection of red peeling spots: so the body warns about the onset of the development of the inflammatory process in the skin layers.

Stages

Psoriasis is usually divided into several stages:

  • stage of progress - characterized by the appearance of small eruptions in the form of papules, which are often accompanied by severe itching;
  • stationary stage - it is characterized by a decrease in the intensity of itching, which is followed by a slight burning sensation;
  • stage of regression - characterized by a weakening of the main symptoms of psoriasis and a significant reduction in itching.

trusted-source[24], [25], [26]

Forms

Itching in psoriasis can be common (throughout the body) or limited (only on one or two sections of the trunk).

A common itching often occurs in the so-called senile psoriasis, when the disease progresses and spreads massively through the body.

If the itching is present only on a separate area of the skin - for example, in the genital area or on the head, then talk about a limited version of the itch.

Complications and consequences

Medical specialists determine the intensity of itching in psoriasis on a special 10-point scale. The strongest itch with psoriasis is estimated at 10 points (very strong, unbearable sensations) - while the affected areas of the skin can bleed.

Severe itching is usually accompanied by an irresistible desire to comb the problem area. Doing this is highly discouraged, as this can lead to the development of hypertrophy of nerve endings. Due to strong or permanent scratching, the skin becomes more sensitive, which leads to an even greater itching.

The brain in response to increased unpleasant sensations becomes more susceptible to external stimuli. The patient begins to form a syndrome of Kebern - a kind of phenomenon that is characterized by a false appearance of itching in places not affected by psoriasis: as a result of constant scratching of such places and they begin to form psoriatic plaques.

Forecast

The prognosis of curability can be considered favorable at an early stage of the disease. The main goal is to prevent relapses, which are usually accompanied by itching. For this, it is required to prevent or stop the inflammatory process, to detect and treat associated infectious diseases and helminthic invasions (which greatly affect immunity), to ensure tranquility of the nervous system, to lower the level of immune T cells in the bloodstream and tissue structures.

If everything is done correctly, then there is a long period of remission - the attenuation of the disease, during which the itching does not disturb psoriasis.
