Roundup Ready soy contains the CP4-enolpyruvylshikimate-3-phosphate synthase (CP4 EPSPS) protein. Serum IgE from two distinct populations of soy-allergic patients were recruited to determine their IgE-binding specificity. One population consisted of 10 adult patients from Europe, whose primary diagnosis was soy food allergy with some also having mite allergy. In addition, ...

Food allergy and atopic eczema (AE) may occur in the same patient. Besides typical immediate types of allergic reactions (i.e. noneczematous reactions) which are observed in patients suffering from AE, it is clear that foods, such as cow's milk and hen's eggs, can directly provoke flares of AE, particularly in ...

Although controlled oral food challenges are considered to be the gold-standard in the diagnosis of food related symptoms, especially if performed in a double-blind, placebo-controlled food challenges (DBPCFC) manner, there are still many unanswered questions and newer aspects, which may explain some pitfalls encountered during oral food challenges. For stopping ...

Food-dependent exercise induced anaphylaxis (FDEIA) is a distinct form of food allergy induced by physical exercise. Symptoms are typically generalized urticaria and severe allergic reactions such as shock or hypotension. Whereas various food items are responsible for the development of FDEIA, wheat is reported to be the allergen with the ...

Issues related to empirical dietary restriction are important, but they have been inadequately studied among children with atopic dermatitis (AD). To evaluate whether any association exists between food atopy, food avoidance, and AD severity, investigators in the present study reviewed all skin prick tests (SPTs) performed between January 2005 and ...

Food is closely associated with the pathogenesis of atopic dermatitis. Food allergy is usually mediated by IgE antibody to specific food proteins and determination of specific IgE antibody is the basis of the common diagnostic test for food allergy. IgG4 have been reported as blocking antibody and the protective effects ...

There are very few reports on allergic reactions to lychee fruit in the literature. We describe the case of a 26-year-old man who developed pruritus, generalized urticaria, and severe angioedema of his lips and tongue with dyspnea within 15 minutes after lychee fruit intake. Although we found no lychee-specific immunoglobulin ...

Mast cells play a central role in many inflammatory diseases and assessment of their activation may be of use to provide objective confirmation of the outcome of food challenge in the diagnosis of food hypersensitivity. However, to date, assessment of mast-cell activation using serum markers has been unsuccessful. The aim ...
Vidal C - - 2007
A 42-year-old woman with no history of atopy reported several episodes of generalized urticaria and shortness of breath after eating shellfish (prawns and barnacles) but with good tolerance of the same foods between episodes. Skin prick tests (SPTs), serum enzyme allergosorbent tests (EAST) for specific immunoglobulin (Ig) E, Western blot ...

The standard of reporting in diagnostic studies has generally been low. Fortunately, this issue has begun to be addressed in recent years through the discussion of important methodological issues in educational series, textbooks, and checklists. Double-blind, placebo-controlled, oral food challenges (DBPCFC) are considered to be the gold standard for diagnosis ...

BACKGROUND: Eosinophilic esophagitis (EE) is often associated with concomitant atopic diseases. In children with EE in whom food allergens have been identified as causative factors, elemental and elimination diets result in an improvement or resolution of symptoms. Most adult EE patients are sensitized to aeroallergens, which cross-react with plant-derived food ...
