The syndrome of delayed allergic reactions to the carbohydrate galactose-alpha-1,3-galactose ("alpha-gal") has become increasingly recognized in allergy and immunology clinics regionally throughout the southeastern USA. Due to the increasing awareness of this unique food allergy, cases have been identified in the northeastern and central USA as well as in Central and South America, Europe, Asia, Scandinavia, and Australia. Clinically, alpha-gal allergy is characterized by reactions to non-primate mammalian meat (e...

Boiled silkworm pupa is a traditional food in Asia, and patients with silkworm pupa food allergy are common in these regions. Still now only one allergen from silkworm, arginine kinase, has been identified. The purpose of this study was to identify novel food allergens in silkworm pupa by analyzing a protein extract after heat treatment. Heat treated extracts were examined by proteomic analysis. A 27-kDa glycoprotein was identified, expressed in Escherichia coli, and purified. IgE reactivity of the recombinant protein was investigated by ELISA...

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 study explored food allergy caused by eating silkworm (Bombyx mori L.) pupae, a traditionally accepted food and animal feed in East and Southeast Asia, and identified two new allergens by proteomic and immunological methods. Proteins isolated from silkworm pupae were separated by two-dimensional gel electrophoresis (2-DE); pooled sera from patients allergic to silkworm pupa proteins were used to detect immunoglobulin E (IgE)-binding proteins by western blotting, and allergens specific for silkworm pupa consumption-caused allergy were visualised with the ECL reagents...

Eczema or atopic dermatitis is a common childhood atopic disease associated with chronicity and impaired quality of life. As there is no cure for the disease, treatment relies on topical and systemic anti-allergic or immunomodulating therapies. Topical corticosteroid, macrolide immunosuppressants, and oral immunomodulating drugs for recalcitrant disease have been the mainstay of therapy. Management of atopic dermatitis must consider the individual symptomatic variability of the disease. Basic therapy is focused on patient/family education, hydrating topical treatment, and avoidance of specific and non-specific provocative factors...

Mulberry (Morus spp.) is a widespread deciduous tree and its fruit is commonly eaten in Korea and eastern Asia. Some reports demonstrate that mulberry fruit is a food allergen in the Mediterranean area. However, there has been no report of systemic allergic reactions after ingesting mulberry fruit in Korea. An 18-year-old boy with a mulberry fruit allergy visited our allergy clinic. He had experienced generalized urticaria, chest tightness, breathing difficulty, and abdominal cramping after ingesting mulberry fruit...

BACKGROUND: The multiple symptoms of chronic fatigue syndrome (CFS) and fibromyalgia resemble those described in patients suffering from autoimmune/inflammatory syndrome induced by adjuvants (ASIA). It has been suggested that chronic metal-induced inflammation might play a role both in CFS and fibromyalgia as well as in ASIA. Humans are exposed to metals mainly through the release of metal ions from corroding dental restorations and orthopedic implants, food, vaccines and jewelry. Metals readily bind to sulphur and other groups in the mitochondria, enzymes and cell proteins...

Monascus-fermented products have been used as dietary food and traditional medicine due to their beneficial effects on circulation and digestive systems in Asia for thousands of years. Besides, monascin and ankaflavin, secondary metabolites from Monascus-fermented products, have proven anti-inflammatory and immunomodulatory effects. In previous research, monascin and ankaflavin ameliorated ovalbumin-induced airway allergic reaction often used as a type I allergy asthma model. Additionally, mast cells play critical roles in type I allergy...

BACKGROUND: Food allergy, eczema and wheeze are early manifestations of allergic disease and commonly co-occur in infancy although their interrelationship is not well understood. Data from population studies are essential to determine whether there are differential drivers of multi-allergy phenotypes. We aimed to define phenotypes and risk factors of allergic disease using latent class analysis (LCA). METHODS: The HealthNuts study is a prospective, population-based cohort of 5276 12-month-old infants in Melbourne, Australia...

The results of long-term epidemiological studies show that the number of people suffering from allergic diseases, especially from food allergies and atopic dermatitis (AD), is still increasing. Although the research thus far has been conducted mainly in Europe, North America, and Asia, there are also data appearing from the first studies in that field among the African population. This may indicate the importance of the problem of allergic diseases. The discovery that loss-of-function mutations in the gene coding filaggrin (FLG) are the cause of ichthyosis vulgaris marked a significant breakthrough in understanding the pathogenesis of allergic diseases...

BACKGROUND: Shellfish allergy in Singapore is highly prevalent, and shrimp allergy is the most common. OBJECTIVE: This study aims to evaluate the clinical characteristics and immunological phenotype of shellfish allergy in this population. METHODS: Patients with self-reported shellfish allergy were recruited from outpatient clinics of three large hospitals and from a population survey. Open oral food challenges (OFC) to glass prawn (Litopenaeus vannamei) and tiger prawn (Penaeus monodon) were carried out on all patients except for those who had a history of severe anaphylaxis...

BACKGROUND: Asian infants appear to be over-represented among patients with clinical food allergy in Australia, but this has not been formally examined at the population level. Any difference in prevalence according to parental country of birth may be secondary to modifiable lifestyle factors. We aimed to quantify (i) differences in the prevalence of peanut allergy by parental country of birth and (ii) contribution of measured environmental exposures to these differences. METHODS: The population-based HealthNuts study in Melbourne, Australia, screened 5276 infants (74% participation) with skin prick tests and sensitized infants underwent food challenge...

Introduction. In Canada, perceived prevalence of food allergy surpasses systematic estimates. Canadian immigrants have been found more likely to rate the risk of food allergy as "high" compared to nonimmigrants. Methods. Qualitative interviews were conducted with 3 key informants and 18 allergic individuals of East and Southeast Asian descent in order to capture their lived experience with food allergies. Results. Participants found food allergies to be more common in Canada than in Asia. Participants also agreed that having a food allergy is more manageable in Canada as a result of the policy environment (e...

BACKGROUND: The longtail tuna (Thunnus tonggol) is widely consumed in Asia. Parvalbumin, the main major allergen of fish, has been well identified in multiple fish species, yet little is known about the allergenic proteins in T. tonggol. Thus, the aim of this study was to characterize the major allergens of T. tonggol using a proteomics approach. METHODS: Raw and boiled extracts of the fish were prepared. Fish proteins were separated by means of SDS-PAGE and two-dimensional (2-DE) electrophoresis...

Buckwheat is known as a health food but is one of the major food allergens triggering potentially fatal anaphylaxis in Asia, especially in Japan and Korea. This study was conducted to investigate the characteristic of enzymatic resistance of buckwheat protein and allergenic potential. Enzymatic resistance of buckwheat protein was performed with in vitro digestibility test in simulated gastric fluid (SGF), pH 1.2, using pepsin and simulated intestinal fluid (SIF) using chymotrypsin. Reactivity of buckwheat proteins to human IgE was performed using six allergic patients sensitized to buckwheat...

Asia is a populous and diverse region and potentially an important source of information on food allergy. This review aims to summarize the current literature on food allergy from this region, comparing it with western populations. A PubMed search using strategies "Food allergy AND Asia", "Food anaphylaxis AND Asia", and "Food allergy AND each Asian country" was made. Overall, 53 articles, published between 2005 and 2012, mainly written in English were reviewed. The overall prevalence of food allergy in Asia is somewhat comparable to the West...
