INTRODUCTION: The NLR family pyrin domain containing 3 (NLRP3)-mediated pyroptosis was positively correlated with the allergic rhinitis progression and was reported to be regulated by SMAD family member 7 (Smad7). Bioinformatics analysis revealed that Smad7 might be targeted by miR-96-5p, and miR-96-5p might be targeted by long noncoding RNA zinc finger antisense 1 (ZFAS1). However, the effects and regulatory mechanisms of the ZFAS1/miR-96-5p/Smad7 functional axis in allergic rhinitis have not been investigated...

INTRODUCTION: Although intramuscular adrenaline is the recommended first-line treatment for anaphylaxis, not all patients receive this treatment. The consequences in daily clinical practice are sparsely described. This study aimed to investigate the treatment administered to anaphylactic patients and the related prognosis. METHODS: A retrospective register-based study of patients with anaphylaxis referred to the allergy centre, Odense University Hospital (2019-2021)...

BACKGROUND: Wildfires are a global concern due to their wide-ranging environmental, economic, and public health impacts. Climate change contributes to an increase in the frequency and intensity of wildfires making smoke exposure a more significant and recurring health concern for individuals with airway diseases. Some of the most prominent effects of wildfire smoke exposure are asthma exacerbations and allergic airway sensitization. Likely due to the delayed recognition of its health impacts in comparison with cigarette smoke and industrial or traffic-related air pollution, research on the composition, the mechanisms of toxicity, and the cellular/molecular pathways involved is poor or non-existent...

INTRODUCTION: Given the lack of data, we aimed to explore which therapeutic endpoints pediatric patients with eosinophilic esophagitis (EoE) and their parents consider to be relevant. METHODS: We created an educational brochure on EoE and a questionnaire, both of which were content-validated by pediatric patients and parents. Validated documents were sent to 112 patients and parents. They ranked the importance (5 levels) of short (during next 3 months) and long-term (≥1 year) treatment effect on symptoms, quality of life, endoscopic inflammation, stricture formation, histological inflammation, and fibrosis...

INTRODUCTION: The primary dietary approach for managing cow's milk allergy (CMA) is the elimination diet. We aimed to compare the growth patterns of children with CMA during and after the elimination diet with healthy peers and identify influencing factors. METHODS: We compared 74 CMA children with age-matched healthy peers. Anthropometric data were collected during the third month of cow's milk elimination (CME) diet (T1), 3 months after diet cessation (T2), and after ≥3 months of normal diet (T3)...

INTRODUCTION: Clinical management of asthma remains as a prevalent challenge. Monotropein (MON) is a naturally occurring cyclic enol ether terpene glycoside with medical application potential. This study aims to evaluate the potential therapeutic effects of MON in the mouse model of chronic asthma. METHODS: An ovalbumin (OVA)-induced asthmatic mouse model was established to evaluate the therapeutic effect of MON at different doses (20, 40, and 80 mg/kg). The potential involvement of protein kinase B (AKT)/nuclear factor kappa B (NF-κB) pathway in the effect of MON was investigated by the administration of an AKT activator SC79...

INTRODUCTION: Acid suppression medications, such as proton-pump inhibitors (PPIs) and histamine-2 receptor antagonists, are commonly prescribed for the treatment of gastroesophageal reflux disease and other gastrointestinal disorders. However, concerns regarding potential long-term side effects are brought up by the overuse of PPIs. This study aimed to investigate the relationship between PPI usage, allergy, and asthma in the general US population. METHODS: Data of individuals aged ≥20 years who had information on PPI use and questionnaires on allergy and asthma in the US National Health and Nutrition Examination Survey (NHANES) 2005-2006 were analyzed...

INTRODUCTION: A growing number of randomized controlled trials (RCTs) have demonstrated the effectiveness of tumor necrosis factor-α (TNF-α) inhibitors in treating non-radiographic axial spondyloarthritis (nr-axSpA). This study aimed to evaluate the efficacy of TNF-α inhibitors in the treatment of nr-axSpA. METHODS: PubMed, EMBASE, Web of Science, and the Cochrane Library databases were systematically searched for relevant RCTs using specific keywords up to June 2023...

The present study was aimed to investigate the changes in type 1, type 2, and regulatory cytokines induced by a Vespula spp. VIT in patients with anaphylaxis to Vespa velutina. METHODS: Twenty consecutive patients with anaphylaxis due to Vespa velutina were treated with Vespula spp. VIT. Serum cytokines (IL-4, IL-5, IL-10, IL-13, and IFN-ɣ) were measured at baseline, 6, and 12 months after starting VIT...

BACKGROUND: Allergy represents a major health problem of increasing prevalence worldwide with a high socioeconomic impact. Our knowledge on the molecular mechanisms underlying allergic diseases and their treatments has significantly improved over the last years. The generation of allergen-specific regulatory T cells (Tregs) is crucial in the induction of healthy immune responses to allergens, preventing the development and worsening of allergic diseases. SUMMARY: In the last decades, intensive research has focused on the study of the molecular mechanisms involved in Treg development and Treg-mediated suppression...

INTRODUCTION: Chronic rhinosinusitis with nasal polyps (CRSwNP) is an immunologic disease, and pyroptosis, an inflammation-based cellular death, strictly modulates CRSwNP pathology, whereas the pyroptosis genes and mechanisms involved in CRSwNP remain unclear. Herein, we explored disease biomarkers and potential therapeutic targets for pyroptosis and immune regulation in CRSwNP using bioinformatics analysis and tissue-based verification. METHODS: We retrieved the transcriptional profiles of the high-throughput dataset GSE136825 from the Gene Expression Omnibus database, as well as 170 pyroptosis-related gene expressions from GeneCards...

INTRODUCTION: Reversion-inducing cysteine-rich protein with Kazal motifs (RECK), a recently discovered inhibitor of matrix metalloproteinase (MMP). There is a large number of chronic obstructive pulmonary disease (COPD) patients worldwide; however, the role of RECK on COPD has not been studied. This study explored the expression of RECK in COPD patients and its effect on neutrophil function to provide a new scientific basis for the prevention and treatment of COPD. METHOD: Fifty patients with acute exacerbation of COPD and fifty healthy controls were enrolled in the study...

INTRODUCTION: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common chronic inflammatory disease of the nose characterized by barrier disruption and environmental susceptibility, and the deletion of ZNF365 may be a factor inducing these manifestations. However, there is no study on the mechanism of action between CRSwNP and ZNF365. Therefore, this study focuses on the effect of the zinc finger protein ZNF365 on the proliferation of nasal mucosal epithelial cells and their defense against Staphylococcus aureus (S...

INTRODUCTION: Iron deficiency is the most common cause of anemia in both sexes, although it is more common in women. Intravenous (IV) iron replacement is preferred in patients who cannot tolerate oral treatment or when iron stores need to be replenished rapidly. In this study, we wanted to share the ferric carboxymaltose (FCM) desensitization protocol that we self-created and successfully applied. METHODS: This retrospective cross-sectional study included patients with a history of hypersensitivity reactions (HSRs) to IV or oral iron replacement and patients who were planned to receive IV iron replacement but were referred to the allergy clinic because of have risk factors (atopic diseases, history of HSR to other drugs, high serum tryptase levels, etc...

BACKGROUND: Dust mites are the leading cause of respiratory allergic diseases worldwide. Allergy to storage mites (SMs) has mostly been related to occupational exposures. However, recent studies have shown that sensitisation to SM, such as Lepidoglyphus destructor (Lep d), is of considerable importance also in urban populations, with high prevalence in dust samples of domestic environments. Co-sensitisation between house dust mites (HDMs) and SM is now regarded as very frequent in some regions, and cross-reactivity between them seems to be narrow...

INTRODUCTION: German cockroach (GCr) aeroallergens are associated with allergic rhinitis and asthma. Vitellogenin (Vg) and vitellin (Vn) are abundant proteins in GCr blood and eggs (including egg cases), respectively, and are possible high molecular mass allergens. Prior efforts to purify Vg/Vn yielded amounts too small for subsequent studies. In this study, we report the affinity purification of Vg/Vn from whole-body defatted GCr powder and determination of the binding of Vg/Vn to anti-GCr IgE...

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can result in a prolonged multisystem disorder termed long COVID, which may affect up to 10% of people following coronavirus disease 2019 (COVID-19). It is currently unclear why certain individuals do not fully recover following SARS-CoV-2 infection. SUMMARY: In this review, we examine immunological mechanisms that may underpin the pathophysiology of long COVID. These mechanisms include an inappropriate immune response to acute SARS-CoV-2 infection, immune cell exhaustion, immune cell metabolic reprogramming, a persistent SARS-CoV-2 reservoir, reactivation of other viruses, inflammatory responses impacting the central nervous system, autoimmunity, microbiome dysbiosis, and dietary factors...
