Epidermal spongiotic Langerhans cell collections, but not eosinophils, are a clue to the diagnosis of allergic contact dermatitis: A series of 170 clinically- and patch test-confirmed cases.

Background: Allergic contact dermatitis cannot be reliably differentiated from other forms of spongiotic/eczematous dermatitis by histology alone. Textbooks and recent studies have variably supported the specificity of dermal eosinophils, eosinophilic spongiosis, and Langerhans cell collections, among other features.

Objective: To assess which histopathologic features favor a diagnosis of allergic contact dermatitis.

Histone acetylation alteration by KAT6A inhibitor WM-1119 suppresses IgE-mediated mast cell activation and allergic inflammation via reduction in AP-1 signaling.

Activation of immunoglobulin E (IgE)-associated mast cells (MCs) triggers the onset of pro-inflammatory signals associated with type I allergic diseases. Although histone acetylation changes have been associated with inflammatory diseases, the impact of lysine-acetyltransferase (KAT) inhibitors on IgE-mediated MCs function is unclear. Potential anti-allergic effects of the KAT6A inhibitor WM-1119 on IgE-mediated MCs activation and allergic inflammation were examined in this study.

Infant mice fed soy-based formulas exhibit alterations in anxiety-like behaviours and the 5-HT system.

Genistein (GEN) is a phytoestrogen with oestrogen-like activity found in many plants. Classified as an endocrine disruptor, GEN is potentially hazardous, particularly during developmental stages. It induces alterations in anxious behaviour, fertility, and energy metabolism, alongside modifications in specific brain circuits.

Clinically relevant evaluation of the antimicrobial and anti-inflammatory properties of nanocrystalline and nanomolecular silver.

Burns and chronic wounds present significant challenges in wound management due to risks of infection, excessive inflammation, and prolonged healing. Silver-based treatments have long been central to burn care, but limitations have prompted the exploration of nanocrystalline silver as an alternative, with its nanoscale properties offering distinct benefits. This paper reviews the structure, properties, mechanisms of action, and clinical applications of nanocrystalline silver in burn and general wound management, with particular emphasis on how wound healing processes inform the application of these dressings.

MPO-ANCA-positive eosinophilic granulomatosis with polyangiitis complicated by alveolar hemorrhage treated with mepolizumab as an induction therapy: Case report.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic vasculitis preceded by bronchial asthma or allergic sinusitis and accompanied by peripheral blood eosinophilia. Immunosuppressive drugs, such as cyclophosphamide in addition to high-dose glucocorticoids, are recommended for induction of remission in patients with severe EGPA. Although mepolizumab is widely recognized as remission induction therapy in non-fatal/non-organ disabling or relapsed/refractory EGPA, its efficacy and safety in induction of remission for severe cases have been ambiguous.

Hymenoptera venom allergy in children.

From a taxonomic point of view, Hymenoptera are subclassified into families: Apidae, including honeybees (Apis mellifera) and bumblebees (Bombus), and Vespidae, which, in turn, are divided into the subfamilies of Vespinae (wasps, including hornets, vespules, dolichovespules) and Polistinae (paper wasp). Hypersensitivity to Hymenoptera venom can be linked to immunological (IgE-mediated or non-IgE-mediated) and non-immunological mechanisms. Reactions are classified into local reactions, large local reactions, systemic reactions, toxic reactions, and unusual reactions.

Artificial intelligence in pediatric allergy research.

Unlabelled: Atopic dermatitis, food allergy, allergic rhinitis, and asthma are among the most common diseases in childhood. They are heterogeneous diseases, can co-exist in their development, and manifest complex associations with other disorders and environmental and hereditary factors. Elucidating these intricacies by identifying clinically distinguishable groups and actionable risk factors will allow for better understanding of the diseases, which will enhance clinical management and benefit society and affected individuals and families.

Cardiovascular complications in vascular connective tissue disorders after COVID-19 infection and vaccination.

Background: COVID-19 infection and vaccination have been reported to confer an elevated risk for cardiovascular events (CVE). We sought to determine whether individuals with an underlying vascular connective tissue disorder including Marfan syndrome (MFS), Loeys-Dietz syndrome (LDS), or vascular Ehlers Danlos syndrome (vEDS) are at increased risk for cardiac events after COVID-19 infection or vaccination.

Methods: 325 respondents self-reported data through a cross-sectional, web-based survey available from 22 November 2021, through 15 March 2022 regarding COVID-19 illness and vaccinations, the occurrence of any CVE, and adverse events following vaccination.

Mechanism of miR-130b-3p in relieving airway inflammation in asthma through HMGB1-TLR4-DRP1 axis.

Asthma is a chronic inflammatory respiratory disease characterized by recurrent breathing difficulties caused by airway obstruction and hypersensitivity. Although there is diversity in their specific mechanisms, microRNAs (miRNAs) have a significant impact on the development of asthma. Currently, the contribution of miR-130b-3p to asthma remains elusive.

Three Cases of Allergic Contact Dermatitis to 2-(Thiocyanomethylthio)benzothiazole in Leather Items.

Background: 2-(Thiocyanomethylthio)benzothiazole (TCMTB) is a fungicide product widely used in the leather industry, particularly since the 1990s. However, reports of allergic contact dermatitis triggered by this chemical are scarce.

Objectives: To investigate three cases of dermatitis following contact with leather products, possibly related to TCMTB.

The antioxidant barrier, oxidative/nitrosative stress, and protein glycation in allergy: from basic research to clinical practice.

Recent studies indicate that oxidative/nitrosative stress is involved in the pathogenesis of asthma, allergic rhinitis, atopic dermatitis, and urticaria. The article aimed to review the latest literature on disruptions in redox homeostasis and protein glycation in allergy patients. It has been shown that enzymatic and non-enzymatic antioxidant systems are impaired in allergic conditions, which increases cell susceptibility to oxidative damage.

Effectiveness of a multimodal therapy protocol for the management of allergic rhinitis: a randomized controlled trial.

Objectives: This study endeavors to comprehensively assess the efficacy of a multimodal therapy protocol in the management and treatment of allergic rhinitis.

Methods: This study employed a randomized controlled trial design, enrolling a total of 100 patients, who were randomly assigned to either the experimental group (receiving multimodal therapy) or the control group (receiving standard treatment), with 50 patients in each group. All enrolled patients were diagnosed based on standard guidelines for allergic rhinitis.

Non-immunoglobulin E-mediated food allergy.

Non-immunoglobulin E (IgE)-mediated food allergies are characterized by delayed gastrointestinal (GI) manifestations that occur after exposure to an inciting food protein; they include food protein-induced allergic proctocolitis (FPIAP), food protein-induced enteropathy (FPE), and food protein-induced enterocolitis syndrome (FPIES). Although the exact mechanisms underlying these disorders are not well understood, non-IgE-mediated food allergies likely represent a spectrum of disease with shared pathophysiological processes. Typically, these non-IgE-mediated food allergies begin in infancy or early childhood, although FPIES can present across the lifespan, with increasing reports in adults in recent years.

Methods: This prospective case-control study included 105 children with AC and 105 age- and sex-matched children with no AC. Clinical data were collected, including BMI, dietary habits, physical activity, and sleep time.

Dematiaceous Molds.

Dematiaceous molds are darkly pigmented environmental molds found worldwide, especially prevalent in tropical and subtropical regions. Common genera include Bipolaris, Cladophialophora, Exophiala, and Alternaria. They cause disease in both immunocompetent and immunocompromised individuals, presenting as cutaneous infections, allergic sinusitis, pneumonia, and, rarely, disseminated infections.

Treatment of food allergy: Immunotherapy, omalizumab, or both.

Food allergy is a common disease which has substantial impacts on the quality of life of patients and their families, and all reactions have the potential for causing life-threatening anaphylaxis. Food allergic individuals currently have 2 FDA approved therapeutic options available to them aside from life-long allergen avoidance: oral immunotherapy (OIT), and omalizumab. OIT for food allergy has been extensively studied in clinical trials and currently provides the greatest level of protection, however it also has a high burden of treatment.

The Psychosocial Burden of Pediatric Food Allergy in the United States: A Population-Based Survey.

Background: Food allergy (FA) affects approximately one in 12 US children, with prevalence increasing. Aside from considerable health care utilization, accumulating research suggests heightened psychosocial burden among this population.

Objective: To characterize FA-related psychosocial burden among a large, nationally representative pediatric sample, and its correlates, including sociodemographic characteristics, comorbid conditions, allergy severity, allergic symptoms, number and type of allergens, and healthcare utilization.

α2-3 Sialic acids-decorated allergens exert a tolerogenic effect on CD4 T cells from Der p 2 - allergic patients.

Background: Allergen-specific immunotherapy (AIT) is so far the only disease-modifying therapy for allergy, resulting in a long-lasting tolerance. However, the existing safety concerns and the need for more efficacious alternatives that shorten the duration of treatment have stimulated research into the development of novel alternatives. Some of these novel alternatives involve modifying allergens with molecules that target innate immunomodulatory receptors to suppress the immune activity of immune cells.
