INTRODUCTION: Children who develop any hypersensitivity reaction to eggs are routinely referred to hospital for Measles-Mumps-Rubella (MMR) vaccination as inpatients to prevent anaphylaxis. We aimed to study the association between hypersensitivity reactions after egg exposure and similar reactions after MMR immunisation; and examine the necessity of hospital admission for vaccination. METHODS: A prospective observational study was conducted in Paediatric Department in Bukit Mertajam Hospital, Penang, between March and December 2014...

BACKGROUND: Hen's egg is widely used in food industry due to its excellent nutritional and processing properties, and Ovalbumin (OVA) is the major allergen of hen's egg white. Ultrasound has been widely used in food processing industry, but effect of high intensity ultrasound on the immunoglobulin G (IgG) binding, immunoglobulin E (IgE) binding and conformational structure of OVA remains unclear. RESULTS: Ultrasound treatment at 600 - 800 W dramatically increased the IgG and IgE binding of OVA with the highest values observed at 600 W...

BACKGROUND: Epidemiological evidence suggests delayed introduction of egg may not protect against egg allergy in infants at risk of allergic disease. OBJECTIVE: To assess whether dietary introduction of egg between 4-6 months in infants at risk of allergy would reduce sensitization to egg. METHODS: We conducted a randomized controlled trial in infants with at least one first-degree relative with allergic disease. Infants with a skin prick test to egg white (EW-SPT) <2mm were randomized at age 4 months to receive whole-egg powder or placebo (rice powder) until 8-months of age, with all other dietary egg excluded...

Food protein-induced enterocolitis syndrome is a non-IgE-mediated food allergy usually diagnosed in infancy. We report a case of a similar syndrome in an adult, following ingestion of egg. We remind clinicians to consider this diagnosis which may present to emergency physicians and gastroenterologists long before an allergist is consulted.

Food allergy is an important health issue that affects up to 8 % of the population. The management of allergic patients involves allergen avoidance and prompts the treatment of accidental reactions, as no curative treatment is available so far in routine practice. Oral immunotherapy (OIT) is a promising therapeutic alternative, but it is associated with frequent allergic reactions and cost-effectiveness issues. In hopes of reducing such reactions, a number of trials have used omalizumab, an anti-IgE monoclonal humanized antibody, as adjunctive therapy in OIT...

BACKGROUND: Our aim was to examine the performance of IMMULITE 2000 assay for specific IgE (sIgE) by comparing it with ImmunoCAP technology in light of a clinical background. METHODS: Measurements of sIgE were done in a selected patient group (N = 569; varied sample size for each allergen) and in a random sample group (N = 100; 8 allergens). sIgE results were correlated with skin-prick test results (selected patients) and medical history (nonselected patients). RESULTS: We have detected fair to excellent correlation and agreement between the results of both assays, despite their methodological differences, both in selected and nonselected patient group (ρc = 0...

BACKGROUND: Many food experts have studied various treatments or processing techniques in order to develop hypoallergenic foods. In a previous study, acid treatment dramatically mitigated the allergenicity of peanut, especially Ara h 2. RESULTS: Gel electrophoresis showed that most protein bands of acid-treated peanut were not detected, but protein bands of egg white became weaker and broader by acid treatment. In immunoblotting using a rabbit antibody, the antigenicity against ovalbumin or ovomucoid in acid-treated egg white was decreased but the antigenicity against Ara h 1 or Ara h 2 in peanut treated with pH 2 acetic acid was completely undetected...

BACKGROUND: The majority of egg-allergic children develop tolerance over time. However, it may take numerous of consecutive egg challenges to get there as no good indices to predict tolerance exist. OBJECTIVE: To investigate whether serial measurements of specific IgE to egg white, ovomucoid, ovalbumin, conalbumin, lysozyme, and egg yolk could improve the specificity of the diagnostic workup and aid in the decision when to rechallenge egg-allergic children. METHODS: The outcome of oral food challenges with hen's egg and corresponding specific IgE levels were evaluated in children referred to The Allergy Center within an 8-year period...

Currently there is no influenza vaccination guidance for European general practitioners. Furthermore, although the European Council recommends a target seasonal influenza vaccination rate of 75% in the elderly (65 years and above) and in anyone aged >6 months with a chronic medical condition, there remain wide discrepancies throughout Europe. A harmonised guideline regarding not only vaccination strategy but also for the consistent diagnosis of influenza across Europe is essential to support a common approach for the implementation of seasonal influenza vaccination across Europe...
