уртикария

Urticaria is a skin disease that is characterized by the sudden formation of pale or pale pink, swollen, extremely itchy rashes called urticaria. Women are affected twice as often as men, and the condition can occur at any age (including breastfeeding).

What is the cause for urticaria?

In less than 30% of cases of urticaria, the underlying cause is found. In many patients, an endogenous (internal) cause of urticaria is suspected. Many external factors can contribute to the different manifestation, frequency and duration of disease activity. These are: heat, pressure, some drugs, friction, alcohol, stress.

Types os urticaria

In general, urticaria can be classified as acute and chronic. The difference between them is determined by the duration of the activity of the disease process. In acute urticaria the appearance of rashes is not longer than 6 weeks, while in chronic urticaria this period is more than 6 weeks. In turn, chronic urticaria can be divided into chronic spontaneous and chronic induced. The classification continues, I will try to be as short as possible. The latter can be induced by physical and non-physical factors:

Chronic induced urticaria due to physical factors: heat, cold, vibration, solar (UV rays), from pressure, dermographism.

Chronic induced urticaria due to non-pshysical factors: aquagenic, cholinergic, contact.

Symptoms and necessary tests

The typical skin rash is called hive. It is characterized by an irregular shape, pale pink / red color and transitional character. Its appearance is preceded and accompanied by intense itching. Hives usually disappear within 24 hours and subsequent ones may reappear.

A number of tests are ordered to find the cause of the disease. It starts with a blood picture with a differential blood picture (it is mandatory to check the level of eosinophils), thyroid hormones and antibodies, ASST / APST (autologous serum skin test / autologous plasma skin test). It is mandatory to check the levels of IgE antibodies. Histological examination is rarely required.
