Possible interaction among hypersensitivity to lipid transfer proteins, chronic urticaria, and hypersensitivity reactions to nonsteroidal anti-inflammatory drugs.

Role of nonallergic hypersensitivity reactions in children with chronic urticaria.

BACKGROUND IgE-independent (pseudoallergic) reactions to food and food ingredients are common in a subgroup of adult patients with chronic urticaria, who have daily spontaneous occurrence of wheals. However, for children with chronic urticaria (duration longer than 6 weeks, no physical influence), no data on the importance of pseudoallergen-induced chronic urticaria are available. Therefore, we...

Functional eicosanoid test and typing (FET) in acetylsalicylic acid intolerant patients with urticaria.

One of the common side effects of acetylsalicylic acid (ASA) is the induction of pseudoallergic reactions that range from urticarial wheals to anaphylactic shock. At present there is no reliable detection method available for the diagnosis of ASA-hypersensitivity and its relation to clinical symptoms. The purpose of the present study was to evaluate the functional eicosanoid typing (FET) score ...
