BACKGROUND: Medication errors are a frequent problem in the accident and emergency (A&E) department. CASE DESCRIPTION: A 17-year-old boy was referred to our A&E department with an anaphylactic reaction to peanuts. Because of various shortcomings in the care process in A&E, adrenaline was administered intravenously instead of intramuscularly, resulting in a broad complex tachycardia. We analysed these shortcomings using the 'Prevention and recovery information system for monitoring and analysis' (PRISMA) method...

BACKGROUND: Clonal mast cell disorders are known to occur in a subset of patients with systemic reactions to Hymenoptera stings. This observation has prompted the question as to whether clonal mast cell disorders also occur in patients with idiopathic anaphylaxis (IA). OBJECTIVE: We sought to determine the prevalence of clonal mast cell disorders among patients with IA, criteria to identify those patients who require a bone marrow biopsy and whether the pathogenesis of IA involves a hyper-responsive mast cell compartment...

BACKGROUND: Amoxicillin (AX) is the betalactam most often involved in IgE-mediated reactions and the diagnosis is mainly based on skin testing (ST) although without optimal sensitivity. We have produced a newly AX derivative, amoxicilloyl-poly-L-lysine (APL), and have analysed its IgE recognition by passive histamine release test (pHRT). METHODS: Patients (N=19) with confirmed AX allergy and with specific IgE positive to AX and controls (N=10) with good tolerance to AX were included...

Akira Sato, Keiichi Ebina
Platelet-activating factor (PAF) is an important mediator of anaphylaxis and is therefore an anti-anaphylactic drug target. We recently reported that synthetic N-terminally biotinylated peptides (BP4-BP29) inhibit PAF by directly interacting with PAF and its metabolite/precursor lyso-PAF. In this study, we investigated whether the biotinylated peptides can inhibit anaphylactic reactions in vivo. In mouse models of anaphylaxis, one of the peptides, BP21, markedly and dose-dependently inhibited hypothermia with a maximum dose-response within 30 min after administration, even at doses 20 times lesser than doses of the known PAF antagonist CV-3988...

BACKGROUND: The inhibitory receptor, FcγRIIB, is expressed on human and murine bone marrow-derived cells and limits inflammation by suppressing signaling through stimulatory receptors. OBJECTIVE: Evaluate the effects of K9.361, a mouse IgG2a alloantibody to mouse FcγRIIB, on murine anaphylaxis. METHODS: Wild-type and FcγR-deficient mice were used to study anaphylaxis, which was induced by injection of 2.4G2 (rat IgG2b mAb that binds both FcγRIIB and the stimulatory receptor, FcγRIII); by actively immunizing IgE-deficient mice, then challenging with the immunizing Ag; and by passive immunization with IgG or IgE anti-TNP mAb, followed by injection of TNP-ovalbumin...

PURPOSE: We aimed to determine if a non-contrast screening MRI is cost-effective compared to a full MRI protocol with contrast for the evaluation of vestibular schwannomas. METHODS: A decision tree was constructed to evaluate full MRI and screening MRI strategies for patients with asymmetric sensorineural hearing loss. If a patient were to have a positive screening MRI, s/he received a full MRI. Vestibular schwannoma prevalence, MRI specificity and sensitivity, and gadolinium anaphylaxis incidence were obtained through literature review...

While an abundance of literature exists describing adverse reactions to vancomycin (eg, nausea, vomiting, red man syndrome, acute kidney injury), there is scarce evidence demonstrating vancomycin anaphylactic reactions requiring cardiopulmonary resuscitation. We report a case of a patient who had 2 separate preoperative episodes of cardiac arrest following vancomycin that occurred 4 weeks apart. Both episodes of anaphylaxis required cardiopulmonary resuscitation, which led to a successful patient outcome. We discuss identification and treatment of vancomycin-induced anaphylaxis...

BACKGROUND: Recently, the nature of the lipid-ligand of Pru p 3, one of the most common plant food allergens in Southern Europe, has been identified as a derivative of the alkaloid camptothecin bound to phytosphingosine. However, the origin of its immunological activity is still unknown. OBJECTIVE: We sought to evaluate the role of the Pru p 3 lipid- ligand in the immunogenic activity of Pru p 3. METHODS: In vitro cultures of different cell types (monocyte-derived dendritic cells (moDCs), PBMCs and epithelial and iNKT-hybridoma cell lines) have been used to determine the immunological capacity of the ligand, by measuring cell proliferation, maturation markers and cytokine production...

L Klimek, S Becker
Molecular component-resolved diagnostics (CRD) are, in addition to its research applications, being increasingly used in daily allergological routine. CRD offers improved diagnostic accuracy via a better understanding of the underlying allergen causing symptoms and helps to distinguish between true sensitization and cross reactions in polysensitized patients, thereby providing an approach for individual personalized therapy. Particularly in food allergies and anaphylaxis, CRD can stratify risks for the recurrence of reactions and their severity...

Anaphylaxis is an acute, life-threatening, multisystem syndrome resulting from the sudden release of mediators by mast cells and basophils. Although anaphylaxis is often under-communicated and thus underestimated, its incidence appears to have risen over recent decades. Drugs are among the most common triggers in adults, being analgesics and antibiotics the most common causal agents. Anaphylaxis can be caused by immunologic or non-immunologic mechanisms. Immunologic anaphylaxis can be mediated by IgE-dependent or -independent pathways...

INTRODUCTION: There is no standardised method for assessing serum total mast cell tryptase (MCT) in anaphylaxis. The consensus equation (peak MCT should be>1.2x baseline tryptase+2mg/L) has been proposed to interpret acute MCT in mast cell activation syndrome (MCAS). AIM: To validate consensus equation in a setting of perioperative anaphylaxis. METHODS: Analyses of suspected perioperative anaphylaxis during general anaesthesia (GA). Anaphylaxis was defined as per World Allergy Organisation (WAO) criteria...

Food allergy is an increasing phenomenon in Australia, with most recent reports of food allergy occurring in 1 in 12 children. A number of studies have demonstrated that children and adolescents with food allergies experience a decreased quality of life across a number of domains. More recent evidence suggests that this population also experiences an increased occurrence of bullying compared to similar school-aged children. Some individuals have reported being bullied because of their allergies, whilst others have reported specific allergy-related-bullying, such as being touched with foods that they are allergic to or having their food being intentionally contaminated with an allergen...

Anaphylaxis is a sudden-onset, severe hypersensitivity reaction that can be potentially fatal. It can often transition to refractory hemodynamic instability, eventually resulting in death. Stress-related cardiomyopathies (SRCs) have multifactorial etiologies, including being linked to excessive catecholamine release in periods of intense stress. This novel case report recounts a SRC caused by contrast-induced anaphylaxis within 1 hour post percutaneous coronary intervention. Both acutely life-threatening conditions may occur simultaneously and are implicated with devastating complications...

BACKGROUND: Peanut oral immunotherapy (POIT) decreases the probability of accidental recurrent systemic reactions but reactions from the therapy itself are frequent. OBJECTIVE: The purpose of this economic analysis was to characterize the potential cost-effectiveness of POIT. METHODS: Cohort simulations were used to evaluate the effect of POIT for children with peanut allergy. A POIT with probiotic was used in the base-case simulation and long-term survival was modeled using age-adjusted mortality together with the risk of food allergy-associated mortality...

Stings of hymenoptera can induce IgE-mediated hypersensitivity reactions in venom-allergic patients, ranging from local up to severe systemic reactions and even fatal anaphylaxis. Allergic patients' quality of life can be mainly improved by altering their immune response to tolerate the venoms by injecting increasing venom doses over years. This venom-specific immunotherapy is highly effective and well tolerated. However, component-resolved information about the venoms has increased in the last years. This knowledge is not only able to improve diagnostics as basis for an accurate therapy, but was additionally used to create tools which enable the analysis of therapeutic venom extracts on a molecular level...
