Background. Allergy to beer is often due to specific proteins in barley and sometimes to lipid transfer protein. Allergy to wine is frequently due to a sensitivity to grape proteins. We present a rare case of allergy to beer, wine, and cider resulting from IgE reactivity to yeasts and moulds which also explained the patient's additional sensitivity to yeast extracts and blue cheese. Case Presentation. The patient's symptoms included throat and facial itching accompanied by mild wheeze and severe urticaria. Diagnosis of allergy to yeast was confirmed by specific IgE testing as well as that to relevant foods and beverages...

Anaphylaxis is a severe, generalized allergic or hypersensitivity reaction that is rapid in onset and may cause death. Epinephrine (adrenaline) can be life-saving when administered as rapidly as possible once anaphylaxis is recognized. This clinical report from the American Academy of Pediatrics is an update of the 2007 clinical report on this topic. It provides information to help clinicians identify patients at risk of anaphylaxis and new information about epinephrine and epinephrine autoinjectors (EAs). The report also highlights the importance of patient and family education about the recognition and management of anaphylaxis in the community...

BACKGROUND: The prevalence of school students at risk of anaphylaxis in Victoria is unknown and has not been previously studied. Similarly, rates of adrenaline autoinjector usage in the school environment have yet to be determined given increasing prescription rates. OBJECTIVES: We sought to determine time trends in prevalence of school children at risk of anaphylaxis across all year levels and the annual usage rate of adrenaline autoinjectors in the school setting relative to the number of students at risk of anaphylaxis...

Epinephrine (adrenaline) is the treatment of choice for anaphylaxis. While other medications, including H1-antihistamines, H2-antihistamines, corticosteroids, and inhaled beta-2 agonists are often used to treat anaphylaxis in the emergency setting, none of these medications has been shown to reverse anaphylaxis. Fatal anaphylaxis is related to the delayed use of epinephrine. In community settings, epinephrine is available as an auto-injector in two doses, 0.15 mg and 0.3 mg. The recommended dose for children is 0...

BACKGROUND: Previous work has shown patients commonly misuse adrenaline autoinjectors (AAI). It is unclear whether this is due to inadequate training, or poor device design. We undertook a prospective randomized controlled trial to evaluate ability to administer adrenaline using different AAI devices. METHODS: We allocated mothers of food-allergic children prescribed an AAI for the first time to Anapen or EpiPen using a computer-generated randomization list, with optimal training according to manufacturer's instructions...

Intramuscular adrenaline is the gold standard treatment for anaphylaxis. Intramuscular injection provides more rapid and higher plasma concentrations than subcutaneous routes. Given the increasing epidemic of obesity patients are at increased risk of subcutaneous delivery, we therefore assessed the depth of subcutaneous tissue in a population of patients with anaphylaxis. Patients already prescribed adrenaline autoinjectors (AAIs) for anaphylaxis were examined with ultrasound, and measurements of skin-to-muscle depth (STMD) at anterolateral thigh and anterior thigh were performed...

AIM: This study aims to determine factors impacting the parental burden in immunoglobulin E (IgE)-mediated food-allergic children (FAC), focusing on attitudes towards adrenaline autoinjectors (AAIs). METHODS: Questionnaires were sent to parents of diagnosed IgE-mediated FAC attending follow-up allergy clinic appointments at two Sydney hospitals in May-September 2013. The questionnaires ascertained parental attitudes, confidence and knowledge regarding AAIs and included the validated, Food Allergy Quality of Life-Parental Burden (FAQL-PB) questionnaire...

In this rostrum we aim to increase awareness of anaphylaxis in infancy in order to improve clinical diagnosis, management, and prevention of recurrences. Anaphylaxis is increasingly reported in this age group. Foods are the most common triggers. Presentation typically involves the skin (generalized urticaria), the respiratory tract (cough, wheeze, stridor, and dyspnea), and/or the gastrointestinal tract (persistent vomiting). Tryptase levels are seldom increased because of infant anaphylaxis, although baseline tryptase levels can be increased in the first few months of life, reflecting mast cell burden in the developing immune system...

Elicitors of anaphylactic reactions are any sources of protein with allergenic capacity. However, not all allergic reactions end up in the most severe form of anaphylaxis. Augmenting factors may explain why certain conditions lead to anaphylaxis. Augmenting factors may exhibit three effects: lowering the threshold, increasing the severity, and reversing acquired clinical tolerance. Common augmenting factors are physical exercise, menstruation, NSAIDs, alcohol, body temperature, acute infections, and antacids...

The prevalence of peanut allergy is thought to be rising with 1 in 70 children affected in the UK. Accidental exposures are frequent and nut allergies are the leading cause of fatal food allergic reactions. Allergic reactions to peanuts are nearly always an immediate, type 1-mediated hypersensitivity response. The typical physiological response associated with such a reaction includes smooth muscle contraction, mucous secretion and vasodilatation. These responses are typically rapid in onset and can lead to systemic effects i...

PURPOSE: Both to evaluate the characteristics of food allergic children who were prescribed an adrenaline autoinjector and to assess whether it was used appropriately. METHODS: The characteristics of food allergic children who were prescribed an adrenaline autoinjector were investigated. Among these children, those who experienced severe anaphylaxis due to inadvertent ingestion were analyzed, as was whether and how the autoinjector was used. RESULTS: An adrenaline autoinjector was prescribed to 139 food allergic children, most often for egg, followed by milk and wheat allergies...

BACKGROUND: Anaphylaxis is a life-threatening emergency. If promptly administered, adrenaline is potentially life-saving. Many food-allergic-children/carers are unsure when to use their adrenaline autoinjectors, contributing to a low quality of life and worse outcomes in the setting of an acute allergic reaction. OBJECTIVES: The aim of this study was to assess the effectiveness of 24-hour telephone access to specialist clinical advice on disease-specific quality of life...

A short-cut review was carried out to establish whether doctors know how to use autoinjectors (for anaphylaxis). Three hundred and twenty-four papers were found of which five presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are shown in table 3. The clinical bottom line is that the majority of doctors studied are unable to use autoinjectors correctly and may therefore be unable to teach patients or parents effectively...

BACKGROUND: Epinephrine autoinjectors are underused for the treatment of anaphylaxis in community settings. Auvi-Q, a novel epinephrine autoinjector, was designed to be intuitive to use and reduce the potential for use-related errors. OBJECTIVE: To compare the bioavailability of 0.3 mg of epinephrine (adrenaline) injected with Auvi-Q and EpiPen in healthy adults. METHODS: In this randomized, single-blind, 2-treatment, 3-period, 3-sequence crossover study, healthy adults (18-45 years old) received a single injection of 0...

OBJECTIVE: This article summarises current knowledge regarding the identification, management and prevention of anaphylaxis, highlighting risk minimisation strategies relevant to general practitioners. DISCUSSION: The most common causes of anaphylaxis are medication, food and insect venom. Medications are the most common cause of anaphylaxis in older adults, particularly antibiotics, anaesthetic drugs, nonsteroidal anti-inflammatory drugs and opiates. Food allergy is the most common cause of anaphylaxis in children, but rarely results in death...
