title: [Urticaria. Sometimes IgE-mediated?].
abstract: There are specific diagnostic recommendations for approaching chronic spontaneous urticaria, physical urticaria and special forms of urticaria. They include the detection of subclinical viral and bacterial infections, particularly with Helicobacter pylori. Frequently an autoimmune urticaria is diagnosed by using the autologous serum test. Less specific findings, such as leukocytosis and elevated CRP can sometimes be helpful in suggesting subclinical infections as the cause of acute urticaria; usually no further procedures are recommended. However, in cases with a long history of intermittent attacks, particularly with severe and generalized symptoms, it is recommended to look for IgE-mediated reactions (e.g. alpha-Gal, Omega-5-Gliadin). In our hands at the Department of Dermatology and Allergy at the Hannover Medical School a standardized set of diagnostic procedures was successfully established, and is now individually completed with selected single allergens and allergen components.
