Urticaria in adults - the causes of

The cause of the disease is toxic-allergic dermatitis, so in most cases it is difficult to find out the true causes of hives. Other provoking factors are heredity, food allergy, diseases of the gastrointestinal tract, focal infection, allergy to medications.

Often, the skin inflammatory process occurs due to a malfunction of the body's immunity. And in general, the appearance of urticaria in adults is due to the sensitivity of the immune system to an increased content of biologically active components. In connection with this, there is an increase in the volume of histamine in the blood serum, and the body's capacity for inactivation decreases.

In patients with urticaria, an increased content of urocaninase enzyme was found. This enzyme is responsible for the ability to inhibit the activity of histidine decarboxylase, while converting the acid histidine into histamine. As a result, there is an overabundance of histamine, and it in turn exerts a toxic reaction and dilates the capillaries.

Bradykinin and serotonin, which enhance the action of histamine, also participate in this process. Great role in the occurrence of hives violations of the vegetative and nervous system. Therefore, the doctor before the beginning of treatment in detail studies the pathogenesis of the patient, to take into account the genetic characteristics of the atopic nature. The development of urticaria in adults is accompanied by anaphylactoid reactions.
