BACKGROUND: Previous murine models have demonstrated interleukin (IL)-33 to be an important mediator of type-2 inflammation and to promote airway hyperresponsiveness in allergic asthma. A number of inflammatory cells produce IL-33 and eosinophils express ST2 mRNA. The relationship between IL-33 and eosinophils in allergic asthma, however, remains unclear. OBJECTIVE: The aim of this work was to evaluate in vitro the effect of allergen inhalation on IL-33 levels and expression of its receptor (ST2L) on eosinophils in allergic asthmatics, and the effect of IL-33 stimulation on eosinophil activity...

BACKGROUND: Hereditary angioedema (HAE) is a genetically heterogeneous autosomal dominant disorder characterized by recurrent episodes of nonpruritic, nonpitting edema increasing after puberty. It can be fatal due to laryngeal or gastrointestinal (GI) involvement with varied and changing frequency of mortality according to studies published from the Western countries. Epidemiological and clinical data of HAE in Asian countries are sparse. We sought to examine the clinical characteristics of HAE patients in Korea...

BACKGROUND: Food allergy is a serious health issue affecting roughly 4% of children, with a substantial effect on quality of life. Chicken egg allergy is frequently observed in infants. Therefore, some of them have to exclude hen's eggs from their daily diet to avoid allergenic symptoms. Hen's egg is composed of 2 soluble parts; one is egg white, which has been characterized as the major source of allergenicity, while the other is egg yolk, which is estimated as a miner source. Only 2 allergens from egg yolk, α-livetin (Gal d 5) and YGP42 (Gal d 6), have been described to date...

BACKGROUND: Although immunosuppressants for therapy of atopic dermatitis (AD) are still being sought, proteasome inhibitors are also potential candidates for the treatment of AD. Proteasome inhibitors exert various effects by blocking proteasomal degradation and help regulate processes such as apoptosis induction via caspase-9, cell cycle progression via cyclins, NF-κB inactivation via IκB, and downregulation of antigen cross-presentation. The cells targeted by proteasome inhibitors are therefore activated cells undergoing proliferation or differentiation, and antigen-presenting cells carrying out protein degradation...

BACKGROUND: Allergic upper airway disease involves pro-inflammatory type-2 cytokines such as IL-5 and regulatory tissue repair mediators, in particular transforming growth factor (TGF)-β1. The TGF-β-superfamily member activin-A displays multiple biological functions and shares certain signalling pathways with TGF-β1. We aimed to examine the coregulation of mucosal activin-A and TGF-β1 in acute allergic and chronic Th2-driven upper airway disease. METHODS: We investigated mucosal cytokine expression profiles and kinetics using RT-PCR after nasal allergen challenges in patients with seasonal allergic rhinitis...

BACKGROUND: The long-term protection provided by venom immunotherapy (VIT) is related to the dose administered and to its long duration; the latter, however, becomes inconvenient for patients in countries like Greece, with many islanders or inhabitants of distant mountainous areas. Maintenance interval prolongation reduces the number of office visits - saving time and money - and as a consequence contributes to the patients' compliance. The aim of this prospective study was to evaluate the safety and efficacy of VIT on a progressively prolonged maintenance interval (PPMI)...

BACKGROUND: IL-17F is involved in the pathogenesis of several inflammatory diseases, including asthma and COPD. However, the effects of steroids on the function of IL-17F signaling mechanisms are largely unknown. One of the transcription elongation factors, positive transcription elongation factor b (P-TEFb) composed of cyclin T1 and cyclin-dependent kinase 9 (CDK9), is known as a novel checkpoint regulator of gene expression via bromodomain-containing protein 4 (Brd4). METHODS: Human airway smooth muscle cells were stimulated with IL-17F and the expression of IL-8 was evaluated by real-time PCR and ELISA...

The T helper 2 (Th2)-type response was considered the hypostasis of allergic airway diseases, including asthma and allergic rhinitis (AR). However, more recent studies have suggested that allergic airway inflammation also depends on innate immunity and is closely related to group 2 innate lymphoid cells (ILC2s). This study evaluated the ILC2 levels of asthma subjects, patients with asthma and AR, and healthy individuals, regarding how to investigate the relationship between clinical data and ILC2 levels. It was found that asthma patients and asthma with AR patients had higher ILC2 levels compared to healthy subjects...

BACKGROUND: Buckwheat (BW) is the source of a life-threatening allergen. Fag e 3-specific serum IgE (sIgE) is more useful than BW-sIgE for diagnosis; however, it is unknown whether Fag e 3-sIgE can predict oral food challenge (OFC) results and anaphylaxis. This study aimed to clarify the efficacy of Fag e 3-sIgE in predicting OFC results and anaphylaxis. METHODS: We conducted a retrospective review of BW- and Fag e 3-sIgE data obtained using the ImmunoCAP® assay system and fluorescent enzyme-linked immunosorbent assay from children who underwent OFC using 3,072 mg of BW protein between July 2006 and March 2014 at Sagamihara National Hospital, Kanagawa, Japan...

BACKGROUND: Forkhead box J1 (FOXJ1) plays pivotal roles in motile cilia formation. However, it remains unclear whether abnormal expression or localization of FOXJ1 in nasal mucosa tissues is associated with allergic rhinitis (AR), in which impaired mucociliary clearance is implicated. OBJECTIVE: We sought to investigate the expression and localization of FOXJ1 in inferior turbinate from patients with AR and controls. METHODS: We assayed mRNA levels of FOXJ1, DNAI1, DNALI1, and DNAH9 by using whole-genome expression array and quantitative real-time polymerase chain reaction...

BACKGROUND: Allergic asthma is common in childhood and is associated with a T-helper type 2 (Th2)-biased immunological response. Exacerbations of asthma are characterised by increased inflammation of the airways, which appears to be driven by interleukin (IL)-33 that can activate pulmonary macrophages. The Th2 cytokine environment of allergic asthma may contribute to exaggerated airway inflammation. OBJECTIVES: To test this, we assessed whether production of pro-inflammatory cytokines by IL-33-stimulated macrophages was enhanced in cells pre-treated with the key Th2 cytokines IL-4 and IL-13...

BACKGROUND: The incidence of rash after aminopenicillin treatment in children with Epstein-Barr Virus (EBV) infection was reported to be 80-100%. A few recent studies suggested that the incidence may be much lower during EBV infection. There are no clear data on the incidence of true drug hypersensitivity among these patients. The aim of this study is to determine the incidence of rash and antibiotic allergy after antibiotic treatment in children with EBV infection. METHODS: Drug hypersensitivity was investigated in antibiotic-treated patients with a positive EBV IgM who developed a rash between 2013 and 2016...

The specificity of several staining methods for mast cells provides the pathologist with a useful means for the differential diagnosis of mast cell tumors. Mast cells stain metachromatically with toluidine blue with greater intensity in cells containing smaller granules. Most stains for mast cells rely on the cell's content of heparin, other glycosaminoglycans, and esterase. As an alternative to histochemical stains, different antibodies have been used to identify mast cells in humans.

BACKGROUND: Fcγ receptors (FcγR) play substantial immune regulatory roles both positively and negatively in pathophysiological processes including allergy and asthma. Compared with FcγRIIB which is classically defined as an inhibitory receptor, mouse FcγRIIIA and its functional human homologue FcγRIIA have been assumed to be activating receptors. However, evidence demonstrating inhibitory regulation by mouse FcγRIIIA has recently been emerging. OBJECTIVE: To dissect the contributory roles of mouse FcγRIIIA (human FcγRIIA) in parallel with FcγRIIB in an ovalbumin (OVA)-induced mouse model of asthma and to preliminarily assess the correlation of the respective FcγR with circulating IgE levels in human asthma patients...

BACKGROUND: It has been suggested that latex-specific IgE analysis may lead to false-positive results, especially in patients with pollen allergy. In the present study, the reasons underlying clinically irrelevant latex-specific IgE positivity were investigated. METHODS: Thirty patients with latex allergy (group 1), 89 patients sensitised to aeroallergens (group 2a), and 98 healthy individuals without allergy (group 2b) were enrolled. Participants from all 3 groups were subjected to skin prick tests with aeroallergens including latex, latex-specific IgE analysis (ImmunoCAP), and nasal provocation test with latex...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the second-most frequent drug type to cause hypersensitivity reactions in children. Asthma is one of the risk factors for NSAID hypersensitivity (NSAID-H) in adult patients. There are limited number of studies evaluating NSAID-H among children with asthma. Our aim was to assess the frequency of confirmed NSAID-H and evaluate the classification of NSAID-H in children with asthma. METHODS: Patients followed with a diagnosis of asthma in our Pediatric Allergy Clinic were evaluated for NSAID-H...

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by the interplay between multiple genetic and environmental factors. The pathogenesis of AD remains incompletely understood. Treatment with topical steroids for chronic AD symptoms has severe side effects and so a new treatment is required. Verbascoside is a hydrophilic phenylethanoid glycoside with antioxidant, anti-inflammatory properties. METHODS: Verbascoside was evaluated in AD-like lesions induced by the repetitive and alternative application of 2,4-dinitrochlorobenzene (DNCB) in BALB/c mice...

Asthma is a chronic disabling respiratory disease that can be triggered by a variety of factors, including allergens, respiratory infections, psychological factors, occupational agents, exercise, atmospheric pollutants, and drugs. The asthma syndrome has been treated for decades according to a "one-fits-all" treatment strategy based on bronchodilators and steroids. With the availability of new forms of treatment targeting the different pathomechanisms of the asthma syndrome, such as anti-immunoglobulin E and cytokine-targeting therapies, the interest in biomarkers that can dis criminate different forms of asthma according to their pathomechanisms has increased...
