Adherence to adrenaline autoinjector prescriptions in patients with anaphylaxis

This study evaluates adherence to adrenaline autoinjector prescriptions in a cohort of well-characterized anaphylaxis patients. The overall retrieval rate was 76% with the highest rate in patients with severe anaphylaxis. Special attention is needed in patients with unknown elicitors and in young adults, comprising the largest proportion of non-adherent patients.Trial registration No intervention performed.

ConclusionsAppropriate policies to manage food anaphylaxis events and anaphylaxis management training were missing in a substantial proportion of camps. Camp-tailored food allergy training is needed given the number of camps reporting food allergy reactions requiring epinephrine.

ConclusionsA multicenter, international study of simulated pediatric anaphylaxis reveals (1) variation in management between institutions in the use of protocols, cognitive aids, and medication formularies, (2) frequent errors involving epinephrine, and (3) latent safety threats related to cognitive aids among multiple sites.

AbstractMast cells (MCs) are portions of the innate and adaptive immune system derived from bone marrow (BM) progenitors that are rich in cytoplasmic granules. MC maturation, phenotype, and function are determined by their microenvironment. MCs accumulate at inflammatory sites associated with atopy, wound healing, and malignancies. They interact with the external environment and are predominantly located in close proximity of blood vessels and sensory nerves. MCs are key initiators and modulators of allergic, anaphylactic, and other inflammatory reactions, by induction of vasodilation, promoting of vascular permeability, r...

ConclusionOur aggregate findings suggest that most APTs, but not dust mite, behave like conventional patch tests to low ‐potency allergens. They are more likely to be positive in patients with chronically inflamed skin and to identify allergens that cause SCD. The higher prevalence of APT positivity to foods in young children is consistent with food allergy as a trigger of AD (also known as SCD) being more common i n children than adults. Positive APTs define patients who may have SCD; negative APTs may guide elimination diets.

Although inoculating humanized mice with a large dose of anti-human Fc εRIα mAb induces anaphylaxis, administering the same mAb through a rapid desensitization approach safely removes nearly all IgE from mast cells and blocks IgE-mediated anaphylaxis.

AbstractPurpose of reviewAnaphylaxis is the most severe form of an allergic reaction and is characterized by being rapid in onset with potentially life-threatening airway, breathing, or circulatory problems; medications are able to provoke immediate acute reactions whose severity varies from mild (i.e., urticaria) to severe reactions (anaphylaxis). The management and prevention of anaphylactic reactions represent a crucial challenge for allergists that must perfectly know the symptoms and the best treatments of this severe disease.Recent findingsAcute treatment of anaphylaxis is based on the immediate administration of adr...

CONCLUSION: IV NEPA was highly effective and safe with no associated hypersensitivity and injection-site reactions in patients receiving AC. IMPLICATIONS FOR PRACTICE: As a combination of a neurokinin-1 (NK1) receptor antagonist (RA) and 5-HT3RA, NEPA offers 5-day chemotherapy-induced nausea and vomiting prevention with a single dose and an opportunity to improve adherence to antiemetic guidelines. In this randomized multinational phase IIIb study, intravenous (IV) NEPA (fosnetupitant/palonosetron) was safe and highly effective in patients receiving multiple cycles of anthracycline-cyclophosphamide (AC)-based chemothe...

Abstract Shrimp allergy, a common form of food allergy is an adverse immunological response to shrimp proteins. BALB/c mice was sensitized by an adjuvant free oral administration of purified tropomyosin, from Metpenaeus dobsonii to characterize intestinal histological responses and immunological protein recognition pattern as it is unpractical in human subjects. Sensitized mice with higher dose of tropomyosin expressed symptoms of anaphylaxis including puffiness around eyes and snout, no activity, tremor and convulsion after challenge. The responses of high level of sera IgE, tropomyosin specific IgE and histamine...

Neutrophil extracellular traps (NETs) have been initially described as main actors in host defense owing to their ability to immobilize and sometimes kill microorganisms. Subsequent studies have demonstrated their implication in the pathophysiology of various diseases, due to the toxic effects of their main components on surrounding tissues. Several distinct NETosis pathways have been described in response to various triggers. Among these triggers, IgG immune complexes (IC) play an important role since they induce robust NET release upon binding to activating FcγRs on neutrophils. Few in vitro studies have documented...
