OBJECTIVES: Rising trends in eosinophilic esophagitis (EoE) have been repeatedly linked to declining Helicobacter pylori (H. pylori) infection, mostly in retrospective studies. We aimed to prospectively evaluate this inverse association. METHODS: Prospective case-control study conducted in 23 centers. Children and adults naïve to eradication therapy for H. pylori were included. Cases were EoE patients, whereas controls were defined by esophageal symptoms and <5 eos/HPF on esophageal biopsies...

We describe a case of a woman who developed three separate episodes of urticaria and ana-phylaxis during exercise after consuming an apple, with immunological evidence that nonspecific lipid transfer proteins (LTP) may have been responsible for these reactions. LTP sensitivity can cause life-threatening allergies and anaphylaxis. Although LTP sensitization is common in Mediterranean countries, the frequency of knowledge and diagnoses is increasing in Europe. Despite the geographic differences, LTP allergy should be kept on sight when facing severe anaphylaxis after consuming LTP-included food...

Background. Follow-up data about the onset of novel food allergies in patients allergic to lipid transfer protein (LTP) are missing. We investigated the occurrence of novel allergies over time in LTP hypersensitive patients. Methods. Sixty-seven LTP-allergic patients recommended to avoid foods responsible for systemic reactions and encouraged to eat other sensitizing foods avoiding the association with known co-factors, were re-evaluated after ≥ 1 year to assess the occurrence of allergy to novel foods. IgE to rPru p 3, rBet v 1, and r Phl p 12 were measured...

BACKGROUND: Non-coeliac gluten-sensitivity (NCGS) has been proposed as a new entity with unknown prevalence and mechanisms, and there is a need for a standardized procedure to confirm the diagnosis. The objective of this study was to characterize the response to an oral gluten-challenge in patients with a symptom-relief when following a gluten free-diet (GFD). METHODS: Twenty patients (14F/6M, age range: 21-62 years) with suspected NCGS, without coeliac disease and wheat-allergy, were included while on a gluten-free diet...

INTRODUCTION: The standard care of severe food allergy in both adults and children means avoidance of allergens. In recent years promising results of oral immunotherapy (OIT) have been reported in children. In adults, information on OIT in severe food allergy is very limited. OBJECTIVE: We aimed to study if OIT is possible in adults. METHODS: We report OIT results in 10 adult patients with milk OIT, nine adult patients with peanut OIT, and four adult patients with egg OIT...

The incidence of atopic diseases, including atopic dermatitis (AD), food allergies, allergic rhinitis, and asthma, has increased in recent decades, and currently affects approximately 20% of the population. Atopic march is the development of AD in infancy and subsequent food allergies, allergic rhinitis, and asthma in later childhood. Patients with infantile eczema may develop typical symptoms of AD, allergic rhinitis, and asthma at certain ages. Some patients' symptoms persist for several years, whereas others may have resolution with aging...

The prevalence of food allergy has risen dramatically in the last two decades. Primary care providers encounter food-allergic children on a daily basis. Although the standard of care has traditionally been strict avoidance of the allergen and advisement to carry an epinephrine autoinjector in case of an accidental exposure resulting in a severe reaction, food allergy research has progressed in the past decade concerning various immunotherapies that may provide an alternate treatment strategy. Oral immunotherapy (OIT), performed under the supervision of an allergist, is the most widely studied of these therapies...

Under normal physiological conditions, eosinophils are present throughout the gastrointestinal tract distal to the squamous oesophagus. Increases in their numbers signify primary and secondary eosinophilic conditions. The rare primary eosinophilic diseases eosinophilic gastroenteritis and eosinophilic colitis affect fewer than ten in 100 000 people, and are characterised by numerous mucosal eosinophils, distributed in sheets and sometimes extending from the mucosa into the submucosa. Pathogenesis of these diseases is poorly understood, but food allergies and intestinal dysbiosis have been implicated...

Three recent publications from Professor Gideon Lack have fundamentally changed our understanding of how to prevent food allergy. His team has shown that early introduction of allergenic foods may prevent food allergy in most but not all high-risk children. Various allergy and paediatric societies around the world are changing their recommendations based on these three studies. It appears there is a window of opportunity to safely introduce allergenic foods to high-risk children. This has resource implications, as some of these children will need testing and food challenges...

Specific immunotherapy (SIT) is one of the important lines for the treatment of food allergy. Efficacy tests for clinical response to SIT are limited and subjective. In this study, we aimed to evaluate the validity of food specific Ig E levels as a biomarker of clinical improvement in children with food allergy treated with oral immunotherapy (OIT). We analysed 184 children with food allergy, 143 had undergone 2 years of food OIT and 41 were on allergen restricted diet and considered as control. All patients were subjected to Double-Blind Placebo-Controlled Food Challenge test (DBPCFC), allergic symptom score calculation, and serum food specific Ig E level before and after oral immunotherapy for treated patients and after 2 year of allergen restricted diet for the control group...
