    The IgE-binding B-cell epitopes of two similar soybean glycinin subunits (Gly m 6) are described.   • Three-dimensional modeling of the glycinin hexamers located most epitopes on the exposed surfaces.   • Comparison with other plant 11S storage protein sequences revealed one dominant and several shared epitopes.   • Common epitope hot spots are often shared between plant storage proteins from diverse families.

    Immunoglobulin E (IgE) are least abundant, tightly regulated and IgE producing B cells are rare. The cellular origin and evolution of IgE responses are poorly understood.

    Background: The prevention of food allergy is a key priority for reducing the burden of allergic disease. Environmental exposures modulate the risk of developing food allergy and some of this may be mediated by the infants’ developing microbiome. However, the role of potentially protective environmental exposures, such as pet ownership, is largely uninvestigated with respect to food allergy.

    The clinical presentation of cow's milk protein allergy (CMPA) in children varies. This retrospective study aimed to investigate the prevalence and clinical manifestations of CMPA in young children who visited for evaluation of iron deficiency anemia (IDA).

    Increasing data suggest that analysis of IgE to peanut components can be clinically helpful and possibly more accurate than IgE to whole peanut. Not all studies examining this topic, however, have used prospective samples, multiple components, and peanut challenges.

    Oral immunotherapy (OIT) can successfully desensitize many peanut allergic subjects, but clinical tolerance diminishes over time upon discontinuation, or low dose maintenance, of peanut. Therefore, in order to improve the efficacy and sustainability of such therapy, we sought to identify biomarkers and clinical tools that can predict therapeutic outcomes and monitor treatment responses.

    The extensive use of allergen molecules in birth cohort studies revealed that atopic sensitization is a sequential IgE response to distinct non–cross-reacting molecules from the same allergenic source (ie, molecular spreading), starting with an initiator molecule. This phenomenon reaches different degrees of progression (monomolecular, oligomolecular, and polymolecular) according to the individual atopic propensity and allergen exposure, thus producing an extreme heterogeneity of IgE sensitization profiles in patient populations. In patients with allergic rhinitis, the broader the IgE molecular sensitization profile, the greater is the risk of asthma and other allergic comorbidities, such as oral allergy syndrome.

    More than 400 occupational sensitizers are identified, but only a limited number of them are characterized on the molecular level.Natural rubber latex (NRL) allergy is an excellent model for improving sIgE measurement with recombinant major allergen.IgE-sensitization profile in patients with baker’s asthma showed great inter-individual variation.For diagnosis of baker’s asthma extract-based diagnostic is still recommended.Increasing the knowledge of occupational allergens and implement and evaluate standardized tools in clinical practice is necessary.

    Corren et al. (Sept. 22 issue)1 report that treatment with lebrikizumab was associated with improved lung function in patients with asthma, and that improvement wasgreater in patients with high pretreatment levels of serum periostin or of the fraction of exhaled nitric oxide (FENO). The authors justifiably emphasize periostin because of its lower intra-patient variability, but in doing so, they raise an important question: what is the relationship between periostin and FENO at baseline in individual patients?

    Background: Biomarkers, preferably noninvasive, that predict asthma inception in children are lacking. Objective: Little is known about biomarkers of type 2 inflammation in early life in relation to asthma inception. We evaluated aeroallergen sensitization, peripheral blood eosinophils, and serum periostin as potential biomarkers of asthma in children.

    Background: Chronic ocular allergic diseases such as vernal kerato conjunctivitis (VKC) and atopic kerato conjunctivitis (AKC) are accompanied by serious comorbidities; however, the underlying pathogenesis remains obscure. Furthermore, diagnosing conjunctival lesions in patients with atopic dermatitis and estimating the severity in AKC are important for the treatment of ocular allergic diseases.

    Allergic sensitization, most notably to perennial aeroallergens, has been defined as a pivotal risk factor for the development of asthma. Recently, it has become evident that both the timing of allergic sensitization and the quantity of sensitization are impor-tant prognostic indicators. Simpson et al have identified an atopy phenotype in children they termed multiple early sensitization. In those children sensitized to multiple aeroallergens at an early age, Simpson et al reported a remarkable increase in risk for asthma inception, severe exacerbations leading to hospitalization, and impaired lung function. This link between early-life sensitization to multiple allergens and increased asthma risk has been replicated in additional cohort studies.

    437 patients aged 34.6±5.4 years, 56.1% males 43.9% females, were assessed over five months in 2018. The allergochip ALEX allowing major allergen component assessment was performed on patients sensitized to house dust mites, using Raptor Analysis MADx, (kUA/L).

    Atopic dermatitis (AD), food allergy, allergic rhinitis, and asthma are common atopic disorders of complex etiology. The frequently observed atopic march from early AD to asthma, allergic rhinitis, or both later in life and the extensive comorbidity of atopic disorders suggest common causal mechanisms in addition to distinct ones. Indeed, both disease-specific and shared genomic regions exist for atopic disorders. Their prevalence also varies among races; for example, AD and asthma have a higher prevalence in African Americans when compared with European Americans.
