Article Synopsis
  • The study aims to understand why peanut allergy (PA) severity differs among patients by analyzing data from 393 cases, focusing on clinical profiles and predictive factors for severity.* -
  • Results indicate that factors such as female sex, age of onset, and specific allergies (e.g., atopic dermatitis, latex) are linked to more severe PA, while birch pollen allergy is associated with milder cases.* -
  • Although some IgE levels (like those to peanut extract and specific components) correlate with PA severity, clinical background factors remain the most effective predictors of an individual patient's risk for severe allergic reactions.*

Background: The heterogeneity and lack of validation of existing severity scores for food allergic reactions limit standardization of case management and research advances. We aimed to develop and validate a severity score for food allergic reactions.

Methods: Following a multidisciplinary experts consensus, it was decided to develop a food allergy severity score (FASS) with ordinal (oFASS) and numerical (nFASS) formats.

Background: Walnut allergy is common across the globe, but data on the involvement of individual walnut components are scarce.

Objectives: To identify geographical differences in walnut component sensitization across Europe, explore cosensitization and cross-reactivity, and assess associations of clinical and serological determinants with severity of walnut allergy.

Methods: As part of the EuroPrevall outpatient surveys in 12 European cities, standardized clinical evaluation was conducted in 531 individuals reporting symptoms to walnut, with sensitization to all known walnut components assessed in 202 subjects.

Diclofenac sodium is widely used in the non-steroidal anti-inflammatory drug in the treatment of pain and inflammation. It is also particularly associated with its adverse effects on avian fauna and linked to environmental issues. The present study was aimed to assess the dose-dependent toxicity of diclofenac sodium on a male reproductive system of rats.

Currently antidiabetic therapeutic strategies are mainly based on synthetic hypoglycemic agent. Antidiabetic drugs are associated with significant adverse effects of hypoglycemia, dysfunction of insulin and weight gain. Nowadays, the novel Dipeptidyl peptidase-IV (DPP-IV) inhibitors unique approach for the management of diabetes has been considered to be safe, as DPP-IV inhibitors reduce blood glucose level by monitoring hyperglycemia including positive effects on body weight as it remains neutral, improves glycated hemoglobin levels and do not induce hypoglycemia.

Aspirin (acetylsalicylic acid) is widely used for cardiovascular prophylaxis and as anti-inflammatory pharmaceutical. An investigation was carried out to evaluate the influence of subchronic dose of aspirin on reproductive profile of male rats, if any. Experimental animals were divided into three groups: control and aspirin subchronic dose of 12.

Unlabelled: Extrapolation of clinical trials results to the general population is always challenging. We analysed 1047 patients diagnosed with an advanced stage disease between 1998 and 2005 in a french administrative department and found a good spread of modern chemotherapy since 1998 and targeted therapy since 2002. Moreover, the outcomes in patients treated according to guidelines are very proximal from those obtained in clinical trials.

House dust mites (HDMs) belong to the most potent indoor allergen sources worldwide and are associated with allergic manifestations in the respiratory tract and the skin. Here we studied the importance of the high-molecular-weight group 11 allergen from Dermatophagoides pteronyssinus (Der p 11) in HDM allergy. Sequence analysis showed that Der p 11 has high homology to paramyosins from mites, ticks, and other invertebrates.

Background: Food allergy can impair health-related quality of life (HRQL). Food Allergy Quality of Life Questionnaires (FAQLQs) have been developed and validated, including an adult form (FAQLQ-AF). HRQL has not, to date, been measured across different European countries using a uniform methodology.

Article Synopsis
  • Food allergy leads to significantly higher health care costs for affected individuals compared to those without allergies, with food-allergic adults incurring around I$927 more annually.
  • The EuroPrevall project analyzed data from multiple European countries, revealing that both adults and children with food allergies consistently face increased medical expenses regardless of demographic factors.
  • The severity of allergic symptoms is a crucial determinant of these costs, indicating that more severe allergies correlate with higher health care expenditures.

In the present study, we investigated the immunomodulatory activity of multi-walled carbon nanotubes (MWCNTs) in peripheral blood mononuclear cells (PBMCs) from healthy donors and mite-allergic subjects. Freshly prepared PBMCs, stimulated or not with Toll-like receptor (TLR)1-9 agonists, a T cell mitogen (phytohemagglutinin A) or mite allergen extract were cultured in the presence or absence of MWCNTs. Secretion of TNF-α, IL-2, IL-5, IL-6, IL-12/23p40 or IFN-γ was quantified in the culture supernatants by ELISA.

Background: Diagnosis and immunotherapy of house-dust mite (HDM) allergy is still based on natural allergen extracts. The aim of this study was to analyze commercially available Dermatophagoides pteronyssinus extracts from different manufacturers regarding allergen composition and content and whether variations may affect their allergenic activity.

Methods: Antibodies specific for several D.

Background: Recombinant DNA technology has the potential to produce allergen-specific immunotherapy vaccines with defined composition.

Objective: To evaluate the effectiveness of a new recombinant birch pollen allergen vaccine in patients with birch pollen allergy.

Methods: A multicenter, randomized, double-blind, placebo-controlled trial was undertaken to compare the following 3 vaccines in 134 adults with birch pollen allergy: recombinant birch pollen allergen vaccine (rBet v 1a), licensed birch pollen extract, natural purified birch pollen allergen (nBet v 1), and placebo.

Although major house dust mite allergen (Der p 1) is carried mainly on large particles (>10 microm), standard bronchial challenge tests (BCT) use nebulizers that deliver smaller particles (sizes from 1 to 5 microm) and may therefore not reflect actual domestic exposure. The objective of this study was to evaluate the influence of particle size of Dermatophagoides pteronyssinus extract on bronchial response. Specific BCT were performed with different mass median aerodynamic diameters (MMAD): 1.
