Background
Double‐blind, placebo‐controlled food challenge (DBPCFC) remains the gold standard for diagnosing food allergy, despite sparse comparisons to open food challenges (OpenFCs). The objective of this retrospective study was to compare severity of symptoms and threshold values (cumulative dose of food allergen eliciting a clinical reaction) in children and adults with peanut allergy, challenged...
Background
Autoreactive immunoglobulin E (IgE) antibodies to self‐peptides within the epidermis have been identified in patients with atopic dermatitis (AD). Prevalence, concomitant diseases, patient characteristics, and risk factors of IgE autoantibody development remain elusive. We aimed to determine IgE autoantibodies in serum samples (n = 672) from well‐characterized patients with AD and controls...
Background
Oral immunotherapy (OIT) is a promising treatment for food allergies. Our aim was to establish the long‐term safety and efficacy of a novel red meat (RM) OIT in galactose‐alpha‐1,3‐galactose (alpha‐gal) allergy in adults.
Methods
Out of 20 patients with confirmed RM allergy, five (41.66%) underwent an early OIT, seven (58.33%) underwent a delayed protocol and eight patients who were...
Autoimmunity is the break of tolerance to self‐antigens that leads to organ‐specific or systemic diseases often characterized by the presence of pathogenic autoreactive antibodies (AAb) produced by plasmablast and/or plasma cells. AAb are prevalent in the general population and not systematically associated with clinical symptoms. In contrast, in some individuals, these AAb are pathogenic and drive...
Background
Food‐induced immediate response of the esophagus (FIRE) is a new phenomenon that has been described in eosinophilic esophagitis (EoE) patients. It is suspected when unpleasant symptoms occur suddenly on contact of the triggering food with the esophageal surface and recur with repeated exposures. It can often be mistaken for pollen‐food allergy syndrome (PFAS) and solid food dysphagia....
Background
The nature of epitopes on Bet v 1 recognized by natural IgG antibodies of birch pollen allergic patients and birch pollen‐exposed but non‐sensitized subjects has not been studied in detail.
Objective
To investigate IgE and IgG recognition of Bet v 1 and to study the effects of natural Bet v 1‐specific IgG antibodies on IgE recognition of Bet v 1 and Bet v 1‐induced basophil activation...
Over the past years, eosinophils have become a focus of scientific interest, especially in the context of their recently uncovered functions (e.g. antiviral, anti‐inflammatory, regulatory). These versatile cells display both beneficial and detrimental activities under various physiological and pathological conditions. Eosinophils are involved in the pathogenesis of many diseases which can be classified...
Background
Sesame is a significant food allergen causing severe and even fatal reactions. Given its increasing prevalence in western diet, sesame is listed as an allergenic food requiring labeling in the United States and EU. However, data on the population reaction doses to sesame are limited.
Methods
All sesame oral food challenges (OFCs), performed either for diagnosis or for threshold identification...
Background
Major fish allergens, including parvalbumin (PV), are heat stable and can withstand extensive cooking processes. Thus, the management of fish allergy generally relies on complete avoidance. Fish‐allergic patients may be advised to consume canned fish, as some fish‐allergic individuals have reported tolerance to canned fish. However, the safety of consuming canned fish has not been evaluated...
Background
Anti‐heat shock protein (HSP) autoantibodies are detected in autoimmune diseases. We sought to ascertain whether anti‐HSP10 IgG is present in patients with CSU and to elucidate the role of HSP10 in CSU pathogenesis.
Method
Using a human proteome microarray, six potential autoantibodies had higher expression in 10 CSU samples compared with 10 normal controls (NCs). Among them, HSP10 IgG...
