Food allergy can result in considerable morbidity, impact negatively on quality of life, and prove costly in terms of medical care. These guidelines have been prepared by the European Academy of Allergy and Clinical Immunology's (EAACI) Guidelines for Food Allergy and Anaphylaxis Group, building on previous EAACI position papers on adverse reaction to foods(More)
BACKGROUND Soybean is considered an important allergenic food, but published data on soybean allergens are controversial. OBJECTIVE We sought to identify relevant soybean allergens and correlate the IgE-binding pattern to clinical characteristics in European patients with confirmed soy allergy. METHODS IgE-reactive proteins were identified from a(More)
Eotaxin and other CC chemokines acting via CC chemokine receptor-3 (CCR3) are believed to play an integral role in the development of eosinophilic inflammation in asthma and allergic inflammatory diseases. However, little is known about the intracellular events following agonist binding to CCR3 and the relationship of these events to the functional response(More)
In less than half a century, allergy, originally perceived as a rare disease, has become a major public health threat, today affecting the lives of more than 60 million people in Europe, and probably close to one billion worldwide, thereby heavily impacting the budgets of public health systems. More disturbingly, its prevalence and impact are on the rise, a(More)
Human basophils are important tools for studying immediate-type hypersensitivity reactions since they release a variety of mediators (e.g., histamine, leukotriene C4, IL-4 and IL-13) following allergen triggering. Several diagnostic tools have been introduced that measure either leukotriene production or the upregulation of surface markers (CD63 and CD203c)(More)
BACKGROUND Soybean is a relevant allergenic food, but little is known about individual threshold doses in soy allergy. OBJECTIVE We sought to determine the clinical characteristics of soy allergy in Europe, including a dose-response curve. METHODS Patients with a history of soy allergy underwent a titrated, double-blind, placebo-controlled food(More)
Infections in humans by Leishmania donovani parasites can result in a fatal disease, visceral leishmaniasis (VL), or in a self-limiting asymptomatic infection. In murine models of the infection employing Leishmania major, the course of the disease can be directed into a VL-like syndrome by interleukin-4 (IL-4)-producing Th2 cells, or cure may result by Th1(More)
BACKGROUND The purpose of this study was to introduce a microdialysis technique, which makes it possible to measure the release of small inflammatory mediators into the extracellular water space in intact human skin in vivo. Using this technique, we have studied the histamine releasing properties of substance P, a putative skin mast cell releasing agent. (More)
BACKGROUND The hazelnut major allergens identified to date are an 18-kd protein homologous to Bet v 1 and a 14-kd allergen homologous to Bet v 2. No studies have reported hazelnut allergens recognized in patients with positive double-blind, placebo-controlled food challenge (DBPCFC) results or in patients allergic to hazelnut but not to birch. OBJECTIVE(More)
BACKGROUND Food allergy to hazelnut occurs both with and without concomitant pollen allergy. OBJECTIVE We sought to evaluate a panel of hazelnut allergens for diagnosis of hazelnut allergy in Spain, Switzerland, and Denmark. METHODS Fifty-two patients with a positive double-blind, placebo-controlled food challenge result with hazelnuts; 5 patients with(More)
