Heat Shock protein 90 α (HSP90α), an main subtype of chaperone protein HSP90, involves important biological functions such as DNA damage repair, protein modification, innate immunity. However, the potential role of HSP90α in asthma occurrence and development is still unclear. This study aimed to elucidate the underlying mechanism of HSP90α in asthma by focusing on the cGAS-STING-Endoplasmic Reticulum stress pathway in inflammatory airway epithelial cell death (i.e., pyroptosis; inflammatory cell death)...

Peanut allergy is a leading cause of severe food reactions. This meta-analysis evaluates the efficacy and safety of epicutaneous immunotherapy (EPIT) compared to placebo for peanut-allergic individuals. After prospectively registering on PROSPERO, we searched three databases (PubMed, Google Scholar, and Cochrane CENTRAL) and 2 trial registries till September 2023. Analysis was conducted via RevMan where data was computed using risk ratios (RR). The Cochrane Risk of Bias tool and GRADE criteria were used to appraise and evaluate the evidence...

Access to the molecular culprits of allergic reactions allows for the leveraging of molecular allergology as a new precision medicine approach-one built on interdisciplinary, basic, and clinical knowledge. Molecular allergology relies on the use of allergen molecules as in vitro tools for the diagnosis and management of allergic patients. It complements the conventional approach based on skin and in vitro allergen extract testing. Major applications of molecular allergology comprise accurate identification of the offending allergen thanks to discrimination between genuine sensitization and allergen cross-reactivity, evaluation of potential severity, patient-tailored choice of the adequate allergen immunotherapy, and prediction of its expected efficacy and safety...

Sublingual immunotherapy is a widely used treatment, and serious adverse reactions such as anaphylaxis are rare. We report two cases of laryngeal edema as adverse reactions to sublingual immunotherapy, which could be continued due to a change in the administration method. Case 1 presents a 15-year-old male suspected to have had anaphylaxis due to the dust at the age of 6 years. He started treatment with Miticure® and developed laryngeal edema 30 minutes after taking the 10000JAU dose on the 10th day. laryngeal edema was treated with intravenous infusion...

Pancreatic cancer is a highly aggressive and often lethal malignancy with limited treatment options. Its late-stage diagnosis and resistance to conventional therapies make it a significant challenge in oncology. Immunotherapy, particularly cancer vaccines, has emerged as a promising avenue for treating pancreatic cancer. Multi-epitope vaccines, designed to target multiple epitopes derived from various antigens associated with pancreatic cancer, have gained attention as potential candidates for improving therapeutic outcomes...

BACKGROUND: The poly-sensitization to Hymenoptera venom makes it difficult to select genuine allergens for immunotherapy and increases patients' costs. The objective of this study was to determine the culprit allergen in dual or triple-sensitized patients to three Hymenoptera venoms through molecular diagnosis and evaluating the results of incorporating the molecular diagnosis with skin tests. METHODS: Thirty-two patients with anaphylactic reactions and dual or triple-sensitization to Hymenoptera venoms in skin tests entered this study...

In the recent report of the Organisation for Economic Coordination and Development (OECD) on Best Practices for Integrating Care to Prevent and Manage Chronic Diseases, an app on rhinitis and asthma (MASK-air®) has been listed. The OECD is a reliable source of evidence-based policy analysis and economic data largely used by governments. It has published several BPs on Public Health. On the 10th of May 2023, the OECD published 13 BPs for Integrating Care to Prevent and Manage Chronic Diseases in the European Union...

This review summarizes recent advances in characterizing the transcriptional pathways associated with outcomes following Oral Immunotherapy. Recent technological advances including single-cell sequencing are transforming the ways in which the transcriptional landscape is understood. The application of these technologies is still in its infancy in food allergy but here we summarize current understanding of gene expression changes following oral immunotherapy for food allergy and specific signatures underpinning the different clinical outcomes of desensitization and remission (sustained unresponsiveness)...

BACKGROUND: - Cyclophilins are ubiquitous panallergens whose epidemiological, diagnostic, and clinical relevance is largely unknown and whose sensitization is rarely examined in routine allergy practice. The aim of this study was to investigate the epidemiological, diagnostic, and clinical relevance of cyclophilin in seasonal allergic rhinitis and its comorbidities. METHODS: - We examined a random sample (25%, n 253) of 1263 Italian children affected by seasonal allergic rhinitis from the "Panallergen in Pediatrics" (PAN-PED) cohort...

INTRODUCTION: IgE-mediated peanut allergy is an important public health problem of increasing prevalence leading to anaphylactic reactions both in children and adults. Allergen-specific oral immunotherapy (OIT) is the single treatment with the potential capacity to modify the course of the disease, but it still faces some drawbacks in terms of efficacy, safety, patients' adherence, and cost. Alternative strategies, including the use of novel adjuvants, to overcome such limitations are highly demanded...

In recent times, the primary approach to treating food allergies involved strict avoidance of the triggering allergen. Many considered this approach as lacking true treatment, leaving patients vulnerable to even small amounts or hidden sources of the allergenic food. Desensitization or Oral Tolerance Induction (OTI) is a studied method aiming for a lasting tolerance to the allergen. The ultimate goal is permanent tolerance, where allergic reactions won't reoccur after new exposure to the triggering allergen, following a period of abstinence...

The treatment of food allergy involves completely removing the allergenic food from the diet, careful label reading, and ingredient awareness. Family education is crucial, understanding alternative names for the allergen. An emergency action plan provided by the doctor, with clear instructions for epinephrine application and when to seek medical attention, is essential. For mild to moderate symptoms, oral antihistamines may be prescribed. Psychological support is necessary due to emotional repercussions. Collaboration with an allergy specialist is crucial for personalized treatment...

Determination of protein concentration in Hymenoptera venoms requires an accurate and reproducible assay as the results will be used to support subsequent proteomic techniques employed in their analyses. However, all protein assay techniques have inherent strengths and weaknesses, demanding their assessment before selecting the most suitable platform for sample analysis. In this study, protein profiles of ant, honeybee, and wasp venoms, and bovine serum albumin (BSA) and hyaluronidase standards were qualitatively assessed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE)...

Cow's milk allergy (CMA) is one of the most common and complex presentations of allergy in early childhood. CMA can present as IgE and non-IgE mediated forms of food allergy. Non-IgE mediated CMA includes food protein-induced enterocolitis syndrome (FPIES), eosinophilic gastrointestinal disorders (EGIDs), and food protein-induced proctocolitis (FPIAP). There are recent guidelines addressing CMA diagnosis, management, and treatment. Each of these guidelines have their own strengths and limitations. To best manage CMA, individualized avoidance advice should be given...

While oral immunotherapy (OIT) for food allergy is a reasonable treatment option, barriers to this procedure's implementation have not been extensively evaluated from a patient perspective OBJECTIVE: We evaluated the barriers patients face during OIT administration, including anxiety and taste aversion, and evaluated the role of healthcare professionals, especially dietitians METHODS: A survey in Canada and the US involved families currently enrolled in food OIT programmes RESULTS: Of responses from 379 participants, fear of reaction was the most common barrier to OIT initiation, with 45...

BACKGROUND: Half (49%) of clinically diagnosed allergic rhinitis (AR) patients are sensitized to house dust mite (HDM). If allergen avoidance and symptomatic medication fail, allergen immunotherapy may be indicated. OBJECTIVE: We investigated safety and tolerability of HDM-sublingual immunotherapy by HDM-SLIT tablets in Dutch daily clinical practice. METHODS: Daily intake of 12 SQ-HDM SLIT-tablet was investigated in a prospective, multicenter, observational study (EUPAS43753)...

Allergic rhinitis (AR) is an IgE-mediated atopic disease that occurs due to inhaled antigens in the immediate phase. Misdiagnosis, insufficient treatment, or no treatment at all are frequent problems associated with the widespread condition known as chronic allergic rhinitis. AR symptoms include runny, itchy, stuffy, and sneezing noses. Asthma and nasal polyps, for example, sometimes occur simultaneously in patients. In order for people living with AR to be as comfortable and productive as possible, treatment should center on reducing their symptoms...

Allergen-specific immunotherapy (AIT) has confirmed its efficacy in improving the symptoms of allergic rhinitis. However, no reliable biomarkers have been identified to predict the efficacy of AIT were found. We aimed to find clinical and immunological markers to predict efficacy in children after 2 years of sublingual immunotherapy (SLIT). A total of 285 children diagnosed with allergic rhinitis were recruited. The clinical efficacy was evaluated by comparing endpoint and baseline symptom and medication scores (SMS)...
