Biomarkers associated with the development of comorbidities in atopic dermatitis (AD) patients have been reported, but have not yet been systematically reviewed. Seven electronic databases were searched, from database inception to September 2021. English language randomized controlled trials, prospective and retrospective cohort, and case–control studies that investigated the association between a...
For persons with immediate allergic reactions to mRNA COVID‐19 vaccines, skin testing (ST) to the vaccine/excipients (polyethylene glycol[PEG] and polysorbate 80 [PS]) has been recommended, but has unknown accuracy. To assess vaccine/excipient ST accuracy in predicting all‐severity immediate allergic reactions upon re‐vaccination, systematic review was performed searching Medline, EMBASE, Web of Science,...
Eosinophilia and eosinophil activation are recurrent features in various reactive states and certain hematologic malignancies. In patients with hypereosinophilia (HE), HE‐induced organ damage is often encountered and may lead to the diagnosis of a hypereosinophilic syndrome (HES). A number of known mechanisms and etiologies contribute to the development of HE and HES. Based on these etiologies and...
Virus infections and T‐cell‐mediated drug hypersensitivity reactions (DHR) can influence each other. In most instances, systemic virus infections appear first. They may prime the reactivity to drugs in two ways: First, by virus‐induced second signals: certain drugs like β‐lactam antibiotics are haptens and covalently bind to various soluble and tissue proteins, thereby forming novel antigens. Under...
Background
Treatment of inflammatory skin diseases, including atopic dermatitis (AD) and psoriasis, is undergoing transformative changes, highlighting the need to develop experimental models of skin inflammation in humans to predict treatment responses.
Methods
We topically or intradermally administered four common sensitizers (dust mite (DM), diphencyprone (DPCP), nickel (Ni), and purified protein...
Introduction
Adolescence is a critical stage of rapid biological, emotional and social change and development. Adolescents and young adults (AYA) with asthma and allergies need to develop the knowledge and skills to self‐manage their health independently. Healthcare professionals (HCP), parents and their wider network play an essential role in supporting AYA in this process. Previous work showed...
Background
Evaluation of perioperative hypersensitivity (POH) is challenging, and accurate screening tools are needed to optimize the diagnostic process. We aimed to assess and validate the diagnostic value of a published algorithm (using tryptase and clinical presentation) to identify appropriate individuals for further testing for IgE‐mediated POH.
Methods
We analysed the clinical presentation...
Background
Apart from Ni2+, Co2+, and Pd2+ ions commonly trigger T cell‐mediated allergic contact dermatitis. However, in vitro frequencies of metal‐specific T cells and the mechanisms of antigen recognition remain unclear.
Methods
Here, we utilized a CD154 upregulation assay to quantify Ni2+‐, Co2+‐, and Pd2+‐specific CD4+ T cells in peripheral blood mononuclear cells (PBMC). Involved αβ T cell...
Background
Allergen exposure chamber (AEC) is a clinical facility that allows exposure to allergenic airborne particles in controlled environment. Although AECs offer stable levels of airborne allergens, the validation of symptoms and other endpoints induced by allergen challenge is key for their recommendation as a plausible tool for the assessment of patients, especially in clinical research. This...
Background
Interleukin (IL)‐33 is an upstream regulator of type 2 (T2) eosinophilic inflammation and has been proposed as a key driver of some asthma phenotypes.
Objective
To derive gene signatures from in vitro studies of IL‐33‐stimulated cells and use these to determine IL‐33‐associated enrichment patterns in asthma.
Methods
Signatures downstream of IL‐33 stimulation were derived from our in...
