Patients allergic to seafood and/or sensitized to Tropomyosin of Skin Prick tests SPT or crustacean origin will may be also be sensitized to edible insects. Aim of the study is to evaluate whether patients allergic to seafood and/or sensitized to Tropomyosin of SPT or crustacean origin may be more often be sensitized to edible insects used as food source.

Detailed description

House dust mite allergy is a common problem in Europe. In addition to inhalant allergies sensitization to mites can be related to food allergy namely seafood. Insects are also widespread food sources in many regions of the world. In this study skin testing and laboratory tests are planned in patients with known house dust mite allergy to evaluate a possible sensitization to insects. Patients must also complete a questionnaire. A drug therapy or other intervention is not planned. Aim of the study is to evaluate whether patients allergic to seafood and/or sensitized to Tropomyosin of SPT or crustacean origin may be more often be sensitized to edible insects used as food source.
