REVIEW
Robert A Wood
This review highlights research advances in food allergy that were published in the Journal in 2015. The world of food allergy research continues to rapidly accelerate, with increasing numbers of outstanding submissions to the Journal. In 2015, important studies on the epidemiology of food allergy were published, suggesting differential rates of food allergy in specific racial and ethnic groups. Even more importantly, studies were published identifying specific risk factors for the development of peanut allergy, as well as specific prevention strategies...

The diagnosis of food allergy is established in cases where an immediate allergic reaction has occurred in the last year to a clearly identifiable allergenic food combined with sensitisation to this allergenic food. In all other cases, a food challenge test is required to establish or reject the diagnosis of food allergy. Although the double-blind placebo-controlled food challenge (DBPCFC) test is considered the gold standard, false-positive and false-negative outcomes occur. The incidence of false-positive outcomes is unknown because the results of DBPCFC tests cannot be further confirmed by other tests...

BACKGROUND: In the Learning Early About Peanut Allergy (LEAP) study, early peanut introduction in high-risk 4-11 month olds was associated with a significantly decreased risk of developing peanut allergy. However, the influences of key baseline high-risk factors on peanut tolerance are poorly understood. METHODS: Secondary analysis was conducted on the publically available LEAP dataset, exploring relationships between peanut tolerance, baseline peanut/egg sensitization, eczema severity/duration, age of introduction, gender, and race...

REVIEW
Jonathan S Tam
Hypersensitivity reactions to foods can have diverse and highly variable manifestations. Cutaneous reactions, such as acute urticaria and angioedema, are among the most common manifestations of food allergy. However, cutaneous manifestations of food allergy encompass more than just IgE-mediated processes and include atopic dermatitis, contact dermatitis, and even dermatitis herpetiformis. These cutaneous manifestations provide an opportunity to better understand the diversity of adverse immunologic responses to food and the interconnected pathways that produce them...

PURPOSE OF REVIEW: Scombroid poisoning is a frequent cause of admission in emergency department. In everyday clinical practice, it can be difficult to discriminate between scombroid syndrome and fish allergy. The aim of this review is to provide the clinician some instruments to make a correct differential diagnosis. RECENT FINDINGS: In the last few years, a better characterization of scombroid syndrome occurred, in particular regarding its possible severe presentations...

REVIEW
Lydia Wong, Chiung Hui Huang, Bee Wah Lee
Crustacean shellfish allergy is an important cause of food allergy and anaphylaxis in Asia. The major allergen in shellfish allergy is tropomyosin, a pan-allergen that is also found in house dust mites and cockroaches. Tropomyosins from house dust mites (HDMs) have a high sequence homology to shellfish tropomyosins, and cross-reactivity between HDM and shrimp tropomyosins has been demonstrated. Exposure to inhaled tropomyosins from house dust mites has been postulated to be the primary sensitizer for shellfish allergy, in a reaction analogous to the oral allergy (inhalant-food) syndrome...

This is a rare case report of systemic allergic reaction to fish allergen ingested through breast milk. Mother ate raw fish more than 3 times a week. Her consumption of fish was associated with urticaria and wheeze in an infant via breast-feeding. Fish-specific IgE antibodies were detected by skin prick test but not by in vitro IgE test. This case demonstrates that fish protein ingested by mother can cause an immediate systemic allergic reaction in offspring through breast-feeding. Although fish intake is generally recommended for prevention of allergy, one should be aware that frequent intake of fish by a lactating mother may sensitize the baby and induce an allergic reaction through breast-feeding...

BACKGROUND: The double-blind, placebo-controlled food challenge test (DBPCFC) is the gold standard in cashew nut allergy. This test is costly, time consuming and not without side effects. Analysis of IgE reactivity to cashew nut components may reduce the need for food challenge tests. METHODS: In a prospective and multicentre study, children with suspected cashew nut allergy underwent a DBPCFC with cashew nut. Specific IgE to cashew nut and to the components Ana o 1, 2 and 3 were determined...

IgE-mediated allergy to wheat proteins can be caused by exposure through ingestion, inhalation, or skin/mucosal contact, and can affect various populations and age groups. Respiratory allergy to wheat proteins is commonly observed in adult patients occupationally exposed to flour, whereas wheat food allergy is more common in children. Wheat allergy is of growing importance for patients with recurrent anaphylaxis, especially when exercise related. The diagnosis of wheat allergy relies on a consistent clinical history, skin prick testing with well-characterized extracts and specific IgE tests...

BACKGROUND: False positive test results in children who are tested for food allergies may lead to inappropriate dietary restrictions. OBJECTIVE: The aim of this study was to report our experience with a 3 year-old boy, who presented with "multiple food allergies" and, however, passed the food challenges, and to review our experience regarding management of children with high specific food IgEs with high total IgE. METHODS: Medical records of 16 children with food challenges were reviewed...

BACKGORUND: Food allergy is a rare disorder among breastfeeding babies. OBJECTIVE: Our aim was to identify responsible allergens in human milk. METHODS: We studied babies developing allergic symptoms at the time they were breastfeeding. Skin prick tests (SPT) were performed with breast milk and food allergens. Specific IgE was assessed and IgE Immunoblotting experiments with breast milk were carried out to identify food allergens. Clinical evolution was evaluated after a maternal free diet...

BACKGROUND: Cow's milk allergy is one of the most common food allergies affecting young children. A subset of milk-allergic individuals can eat baked milk without allergic symptoms which is beneficial in terms of prognostication and liberalization of the diet. A retrospective study suggested that skin prick testing (SPT) with a baked milk (muffin) slurry may provide a sensitive means of predicting the outcome of a medically supervised baked milk oral food challenge. We evaluated the predictive value of SPT with baked milk to identify unheated milk-allergic children who are able to safely eat baked milk...

BACKGROUND: Although exclusive breastfeeding at least 4 to 6 months has been recommended to prevent IgE-mediated cow's milk allergy (IgE-CMA), early introduction of food allergens has received a lot of attention in recent years for the prevention of food allergies. OBJECTIVES: We aimed to determine whether IgE-CMA is associated with a feeding pattern in early infancy. METHODS: In a case-control study, we retrospectively compared the patient background, past history of atopic dermatitis, bronchial asthma, family history of allergic diseases, feeding patterns in early infancy, and the reason for choosing early infancy feeding patterns of patients with IgE-CMA with age- and sex-matched healthy controls using a questionnaire completed by their mothers...

Importance: The reported prevalence of peanut allergy among children in the United States has increased more than 3-fold in the last 20 years. Medical guidelines on the introduction of peanut as well as other allergenic foods have evolved with the emerging evidence that an early introduction to these foods is more beneficial than a delayed introduction. This review highlights the studies that have led to the evolving guidelines on peanut introduction in infants. Observations: The prevalence of peanut allergy has increased despite the publication of guidelines from the American Academy of Pediatrics in 2000, which recommended a delayed introduction of peanut...

PURPOSE: This study aimed to evaluate the safety and efficacy to induce clinical desensitization to cow's milk (CM) of an oral immunotherapy (OIT) protocol in a pediatric population with cow's milk allergy (CMA). In addition, the immune responses against β-casein, of peripheral blood mononuclear cells (PBMCs) from CMA patients, before and after the protocol were evaluated and compared to a nonallergic population. METHODS: A group of 20 children with IgE-mediated CMA and 15 nonallergic children were recruited...
