Background: Food allergies are becoming more prevalent globally. The purpose of this study was to investigate the epidemiology of food allergies in Taiwan.
Methods: In 2017, a food allergy questionnaire was administered to 6-7-year-old children, 13-14-year-old adolescents, and their parents in Taipei. The results were compared to those from a previous survey conducted in 2004.
Results: A total of 16,200 questionnaires were completed, revealing a rise in the prevalence of food allergies from 7.7% to 10.4% in the pediatric group and from 6.4% to 12.5% in the adult group. Peanut allergies also increased to 1.1%. Shrimp and crabs were the most common allergens, with urticaria being the most common symptom. Shortness of breath or wheezing occurred in 10% of individuals, while 2.1% experienced syncope or shock, and 0.1% were admitted to an intensive care unit. Personal history of allergic rhinitis and atopic dermatitis, as well as family histories of food allergies, were risk factors for food allergy in 6-7-year-old children. In the 13-14-year-old group, personal history of asthma, allergic rhinitis, or atopic dermatitis, recent use of acetaminophen, and living with dogs were risk factors. Females, personal histories of asthma, allergic rhinitis, atopic dermatitis, and moist and damp at home were risk factors in adults. Breastfeeding was a protective factor in 6-7-year-old children.
Conclusion: The increasing prevalence of food allergies, including peanut allergies, in Taiwan warrants attention from physicians to provide appropriate care and education to patients with food allergies. The protective effect of breastfeeding against food allergies shall be emphasized.

Early life acute infections and risk for cow's milk protein allergy or atopic dermatitis at 6 months of age in high risk for allergy infants.
Front Pediatr
December 2024
Department of Nutrition & Dietetics, School of Health Science & Education, Harokopio University, Athens, Greece.
Background: Early life infections (ELIs), encompassing both viral and bacterial types, occur within the first six months of life. Influenced by genetic host factors and environmental conditions, the relationship between ELIs and subsequent allergic manifestations, particularly cow's milk protein allergy (CMPA) and atopic dermatitis (AD), is complex and not fully understood.
Objective: The aim of the current study was to examine the potential interplay between nutrition, infections, and allergic manifestations in the first six months of life in infants with a family history of allergies, who were either exclusively breastfed (EBF) or fed a combination of breast milk and standard (SF) or partially hydrolyzed infant formula (pHF).

Background: Peanut allergy (PA) is one of the most prevalent food allergies with a lack of favorable safety/efficacy treatment. A cucumber mosaic virus-like particle expressing peanut allergen component Ara h 2 (VLP Peanut) has been developed as a novel therapeutic approach for PA.
Objective: We assessed the tolerogenic properties and reactivity of VLP Peanut.

Background: Sesame allergy (SA) is a growing concern because of its association with severe reactions and the limited knowledge of long-term outcomes.
Objective: This retrospective study aimed to identify the risk factors influencing persistent SA (PSA) in children to improve management and select suitable candidates for oral immunotherapy (OIT).
Methods: We analyzed the electronic medical records of 84 children with confirmed SA, as defined by consistent clinical reactions and immunoglobulin E (IgE)-mediated sensitization.
