Japanese version of the food allergy quality of life questionnaire 10: An easy-to-use instrument.

Background: The health-related quality of life (HRQL) of people with food allergies should be evaluated to provide high-quality medical care. Currently, there is no available easy-to-use and reliable instrument for assessing HRQL clinically in Japan.

Methods: The Food Allergy Quality of Life Questionnaire 10 (FAQLQ10) in English was translated into Japanese, and this was referred to as the Japanese version of the Food Allergy Quality of Life Questionnaire 10 (FAQLQ10-J).

Formulation of adult food-protein-induced enterocolitis syndrome diagnostic scoring system differentiating from immediate-type food allergy.

Background: Adult food-protein-induced enterocolitis syndrome (FPIES) has recently been recognized, and there are no international diagnostic criteria for this disease. Differentiating adult FPIES from immediate-type food allergy reactions and providing specific treatment for each in an emergency are important, but methods have not been developed.

Objective: To develop a diagnostic scoring system for adult FPIES by comparing it with an immediate-type food allergy (IgE-mediated food allergy [IgE-FA]).

Evaluation of Deficient Nutrients in Infants and Toddlers Mainly Taking Amino Acid-Based Elemental Formulas: An Exploratory Study.

Introduction: This study evaluated nutrient deficiencies in infants and toddlers with inflammatory bowel disease (IBD) and eosinophilic gastrointestinal disorders (EGIDs), whose primary nutritional source is elemental formulas (EFs).

Methods: The nutrient status of children with IBD and EGID aged 6 months to 6 years was evaluated.

Results: Twenty-one children fed with EFs (EF group) and 25 controls (CL group) were enrolled.

A nationwide survey of non-IgE-mediated gastrointestinal food allergies in neonates and infants.

Background: Non-IgE-mediated gastrointestinal food allergies (non-IgE-GIFAs) seem to be increasing rapidly worldwide. However, nationwide studies have been limited to food-protein-induced enterocolitis (FPIES) and food-protein-induced allergic proctocolitis (FPIAP), with little attention to other non-IgE-GIFA subgroups. The aim of this study was to elucidate the clinical features of all patients with non-IgE-GIFAs, not just certain subgroups.

Development of an action plan for acute food protein-induced enterocolitis syndrome in Japan.

Reports of food protein-induced enterocolitis syndrome (FPIES) in Japan have been increasing. However, the disease itself and the treatment options are poorly understood by both patients and medical professionals. The objective of this study is to develop an action plan for acute FPIES in Japan.

Comparison of adult food protein-induced enterocolitis syndrome to crustaceans and immediate-type food allergy.

Background: Food protein-induced enterocolitis syndrome (FPIES) is increasingly found in adults. FPIES requires different treatment from immediate-type food allergy (FA) in emergency medicine. However, no comparison of the clinical presentations of these diseases has been reported.

[A CASE OF INDUCIBLE LARYNGEAL OBSTRUCTION UNSUCCESSFULLY TREATED AS SEVERE ASTHMA WAS WELL CONTROLLED AFTER APPROPRIATE DIAGNOSIS AND INSTRUCTION OF THERAPEUTIC BREATHING MANEUVERS].

Inducible laryngeal obstruction (ILO) refers to respiratory disorders caused by airflow limitation in the larynx, including vocal cord dysfunction, and may sometimes be misdiagnosed as bronchial asthma (BA). Here, we report the case of an 11-year-old boy diagnosed with BA in infancy. He was referred to our Allergy Center and was taking a high dose of inhaled corticosteroids (ICS) due to frequent coughing from the age of 10 years and persistent coughing following COVID-19 infection at the age of 11.

STAT6 gain-of-function variant exacerbates multiple allergic symptoms.

Background: Allergic diseases were long considered to be complex multifactorial disorders. However, recent findings indicate that severe allergic inflammation can be caused by monogenic immune defects.

Objectives: We sought to clarify the molecular pathogenesis of a patient with early-onset multiple allergic diseases, a high serum IgE level, hypereosinophilia, treatment-resistant severe atopic dermatitis with increased dermal collagen fiber deposition, and eosinophilic gastrointestinal disorder with numerous polypoid nodules.

Tolerability and safety of a new elimination diet for pediatric eosinophilic gastritis and duodenitis.

Background: Non-esophageal eosinophilic gastrointestinal disorders (non-EoE EGIDs) are chronic inflammatory disorders with massive infiltration of eosinophils into the gastrointestinal tract. Food elimination diets are potentially effective treatments. But the existing dietary therapies have various weak points.

Remission of Acute Food Protein-Induced Enterocolitis Syndrome Confirmed by Oral Food Challenges in Japan.

The oral food challenge test (OFC) is the gold standard for evaluating the remission of food protein-induced enterocolitis syndrome (FPIES). Few acute FPIES remissions confirmed by OFC were reported. This study aimed to examine the OFC for Japanese children with acute FPIES to evaluate its remission.

International Consensus Recommendations for Eosinophilic Gastrointestinal Disease Nomenclature.

Background & Aims: Substantial heterogeneity in terminology used for eosinophilic gastrointestinal diseases (EGIDs), particularly the catchall term "eosinophilic gastroenteritis," limits clinical and research advances. We aimed to achieve an international consensus for standardized EGID nomenclature.

Methods: This consensus process utilized Delphi methodology.

[ACUTE TREATMENT AND LONG-TERM PROGNOSIS OF SEVERE PROTEIN-LOSS IN ATOPIC DERMATITIS (SPLAD)].

Background: Atopic dermatitis (AD) in early infancy can lead to severe protein-loss in atopic dermatitis (SPLAD). The aim of this study was to elucidate the prognosis of SPLAD.

Methods: This was a single-center, retrospective, observational study based on medical records.

Comparison of Nonesophageal Eosinophilic Gastrointestinal Disorders with Eosinophilic Esophagitis: A Nationwide Survey.

Background: Eosinophilic esophagitis (EoE) has increased rapidly and has been well characterized. However, no nationwide survey has been conducted regarding non-esophageal eosinophilic gastrointestinal disorders (non-EoE EGIDs), and they remain poorly understood.

Objective: To compare the clinical features and natural histories of non-EoE EGIDs and EoE by using the same questionnaire, for all ages.

Avoidance of Hen's Egg Based on IgE Levels Should Be Avoided for Children With Hen's Egg Allergy.

Although hen's egg (HE) allergy was thought to be usually resolved by late childhood, majority of HE allergy patients with a high level of egg white (HEW)-specific IgE could not acquire tolerance for HE by age 8 years. The aim is to investigate whether the avoidance of HE until 6 years of age increased the risk of heated HE allergy at age 6 years. This was a retrospective case-control study.

Pediatric patient with eosinophilic esophagitis and pollen-food allergy syndrome.

The incidence of eosinophilic esophagitis (EoE) and pollen-food allergy syndrome (PFAS) is increasing worldwide, and coexistence of these 2 diseases has been reported in adults. In children, however, these conditions have not been reported as comorbidities probably because sensitization to aeroallergens occurs at an older age. We report the case of a boy with EoE and PFAS.

[A CASE OF EOSINOPHILIC GASTROENTERITIS FOUND BY PICA DURING ORAL IMMUNOTHERAPY].

Eosinophilic esophagitis has been reported as a complication of oral immunotherapy (OIT), but there are only a few reports of eosinophilic gastroenteritis (EGE) occurring after OIT. EGE causes eosinophil infiltration into the gastrointestinal (GI) tract and is characterized by various digestive symptoms. We report the case of a 6-year-old boy with EGE.

Serum Biomarkers for the Diagnosis of Eosinophilic Esophagitis and Eosinophilic Gastroenteritis.

Objective Clinically useful serum biomarkers for the diagnosis and monitoring of eosinophilic gastrointestinal diseases are not available. This study was conducted to examine the possible value of eosinophil-related proteins as serum biomarkers. Methods The serum concentrations of 49 cytokines, chemokines, and other proteins were measured in 29 patients with eosinophilic gastrointestinal diseases and 80 controls.

Factors Associated with Development of Food Allergy in Young Children after Liver Transplantation: A Retrospective Analysis of 10 Years' Experience.

Background: Although development of food allergy after liver transplantation is most commonly described in young children, little is known about identification of young liver-transplant recipients who are at risk of food allergy.

Objective: This study aimed to identify the types of food allergy and the risk factors for the development of food allergy after liver transplantation.

Methods: This was a retrospective analysis of pediatric liver transplant recipients in our organ transplantation center during 2005-2015.

Gene Expression Patterns in Distinct Endoscopic Findings for Eosinophilic Gastritis in Children.

Background: Eosinophilic gastritis (EG) is clinicopathologically characterized by both marked gastric eosinophilia and clinical symptoms. The endoscopic findings in EG vary among patients, leading to clinical confusion. However, little is known about the relationship between precise endoscopic findings and the pathophysiological process responsible for EG.
