Artificial intelligence in pediatric allergy research.

Unlabelled: Atopic dermatitis, food allergy, allergic rhinitis, and asthma are among the most common diseases in childhood. They are heterogeneous diseases, can co-exist in their development, and manifest complex associations with other disorders and environmental and hereditary factors. Elucidating these intricacies by identifying clinically distinguishable groups and actionable risk factors will allow for better understanding of the diseases, which will enhance clinical management and benefit society and affected individuals and families.

A gut commensal protozoan determines respiratory disease outcomes by shaping pulmonary immunity.

The underlying mechanisms used by the intestinal microbiota to shape disease outcomes of the host are poorly understood. Here, we show that the gut commensal protozoan, Tritrichomonas musculis (T.mu), remotely shapes the lung immune landscape to facilitate perivascular shielding of the airways by eosinophils.

Food Allergy Genetics and Epigenetics: A Review of Genome-Wide Association Studies.

In this review, we provide an overview of food allergy genetics and epigenetics aimed at clinicians and researchers. This includes a brief review of the current understanding of genetic and epigenetic mechanisms, inheritance of food allergy, as well as a discussion of advantages and limitations of the different types of studies in genetic research. We specifically focus on the results of genome-wide association studies in food allergy, which have identified 16 genetic variants that reach genome-wide significance, many of which overlap with other allergic diseases, including asthma, atopic dermatitis, and allergic rhinitis.

Immunomodulatory features of MSC-derived exosomes decorated with DC-specific aptamer for improving sublingual immunotherapy in allergic mouse model.

Introduction: Sublingual immunotherapy (SLIT) is an effective and injection-free route for allergen-specific immunotherapy (AIT). Mesenchymal stromal/stem cell (MSC)-derived exosomes (Exo) has been identified as a novel delivery platform with immunomodulatory capacities. In addition, targeting agents such as aptamers (Apt) have been extensively used for specific delivery approaches such as direct delivery of allergen formulations to dendritic cells (DC) to improve the efficacy of specific immunotherapy.

Paraoxonase-1 Is a Pivotal Regulator Responsible for Suppressing Allergic Airway Inflammation Through Adipose Stem Cell-Derived Extracellular Vesicles.

Although adipose stem cell (ASC)-derived extracellular vesicles (EVs) are as effective as ASCs in the suppression of Th2 cell-mediated eosinophilic inflammation, the role of identified pulmonary genes has not been well documented. Thus, we assessed the immunomodulatory effects of paraoxonase-1 (PON1) on allergic airway inflammation in a mouse model of asthma. Five-week-old female C57BL/6 mice were sensitized to ovalbumin (OVA) by intraperitoneal injection and challenged intranasally with OVA.

Single-Cell Analysis: A Method for In-Depth Phenotyping of Cells Involved in Asthma.

Asthma is a chronic inflammatory lung disease with high prevalence, making it one of the most common chronic conditions worldwide. Its pathophysiology is influenced by a range of genetic and environmental factors, resulting in a complex and heterogeneous disease profile. Asthma is primarily associated with a type 2 (T2) immune response, though non-T2 endotypes also contribute to disease pathology.

Early-life IL-4 administration induces long-term changes in microglia in the cerebellum and prefrontal cortex.

Microglia are crucial for brain development and their function can be impacted by postnatal insults, such as early-life allergies. These are characterized by an upregulation of interleukin (IL)-4 levels. Allergies share a strong comorbidity with Autism Spectrum Disorders (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD).

How the early life microbiome shapes immune programming in childhood asthma and allergies.

Despite advances in our understanding of their diagnosis and treatment, pediatric allergies impose substantial burdens on affected children, families, and healthcare systems. Further, the prevalence of allergic diseases has dramatically increased over the past half-century, leading to additional concerns and concerted efforts to identify the origins, potential predictors and preventions, and therapies of allergic diseases. Together with the increase in allergic diseases, changes in lifestyle and early-life environmental influences have corresponded with changes in colonization patterns of the infant gut microbiome.

Epidemiology of asthma across the ages.

In the last three decades, the overall prevalence of asthma appears to be plateauing, although large geographical and socioeconomic variation is evident. Overall, asthma prevalence slightly decreased in most age groups, except for school-aged children. Of note, asthma mortality steadily decreased, potentially highlighting improved asthma management strategies.

Cytokines reprogram airway sensory neurons in asthma.

Nociceptor neurons play a crucial role in maintaining the body's homeostasis by detecting and responding to potential environmental dangers. However, this function can be detrimental during allergic reactions, as vagal nociceptors contribute to immune cell infiltration, bronchial hypersensitivity, and mucus imbalance in addition to causing pain and coughing. Despite this, the specific mechanisms by which nociceptors acquire pro-inflammatory characteristics during allergic reactions are not yet fully understood.

Atopic dermatitis.

Atopic dermatitis (AD) is a common, chronic skin disorder that can significantly impact the quality of life (QoL) of affected individuals as well as their families. Although the pathogenesis of the disorder is not yet completely understood, it appears to result from the complex interplay between defects in skin barrier function, environmental and infectious agents, and immune dysregulation. There are no diagnostic tests for AD; therefore, the diagnosis is based on specific clinical criteria that take into account the patient's history and clinical manifestations.

Household fuel use, smoking and prevalence of self-reported allergic rhinitis in university students in Palestine: a cross-sectional study.

Purpose: In Palestine, few studies investigated the prevalence of allergies and the factors associated with their occurrence. An online survey was conducted on health complex University students in Jerusalem to determine the prevalence of allergy rhinitis (AR) and its relationship with indoor environmental exposures.

Methods: This study employed a modified online Google form of the Global Asthma Network's Adult Questionnaire.

Dietary exposure to mixtures of chemicals in the first year of life and allergic and respiratory diseases up to 8 years in the French EDEN mother-child cohort.

Exposure to environmental chemicals has been associated with higher risk of childhood allergies. This study aimed to examine the association between infant's dietary exposure to mixtures of chemicals and allergic and respiratory multimorbidity in childhood. Dietary exposures were assessed at 8 and 12 months in 724 and 745 children of the EDEN cohort.

Prenatal exposure to environmental bisphenols over time and their association with childhood asthma, allergic rhinitis and atopic dermatitis in the ECHO consortium.

Concerns persist about the potential impact of prenatal exposure to bisphenols (BP) and their replacement analogues on childhood asthma and allergies. Previous studies on single and small cohorts had limited statistical power, few investigated analogues BPF and BPS, and even fewer examined atopic outcomes. Our objective was to assess whether prenatal exposures to individual environmental bisphenols (BPA, BPF, BPS) influence risk of childhood asthma, allergic rhinitis, and atopic dermatitis.

Incorporating Aeroallergen Exposure Metrics into Clinical Asthma Care: A Pilot Study Using A Mixed-Methods Survey to Assess Aeroallergen Knowledge, Perceived Asthma Control, and Mitigation Strategies in Households of Children with Asthma.

Mitigation of household allergens is associated with the reduction of asthma exacerbations in those with allergic asthma and is recommended in recent asthma guidelines. However, we need to better understand patient knowledge of aeroallergens in their homes prior to integrating direct allergen measurement methods into standard asthma care. We conducted a mixed-methods sequential pilot study consisting of a survey and virtual interview with caregivers of children aged 3 to 15 with asthma diagnosis (any severity) about asthma control, household environment, mitigation knowledge and strategies, and knowledge of allergens and asthma.

Effects of TMEM232 Variant on Infant Atopic Dermatitis According to Maternal Factors.

Atopic dermatitis (AD) is caused by interactions between genetic susceptibility and environmental factors. Transmembrane protein 232 () is one of the genes strongly implicated in AD. In the present study, we aimed to investigate the association between AD with variants within based on maternal factors, including a history of allergic diseases, and sensitization to Der f.

Association of environmental pollutants with asthma and allergy, and the mediating role of oxidative stress and immune markers in adolescents.

Background: Asthma and allergic diseases are among the common causes of morbidity and mortality globally. Various environmental pollutants are linked to the development of asthma and allergic diseases. Evidence on the role of oxidative stress and immune markers in the association of environmental pollutants with asthma and allergy is scant.

Global change, climate change, and asthma in children: Direct and indirect effects - A WAO Pediatric Asthma Committee Report.

The twenty-first century has seen a fundamental shift in disease epidemiology with anthropogenic environmental change emerging as the likely dominant factor affecting the distribution and severity of current and future human disease. This is especially true of allergic diseases and asthma with their intimate relationship with the natural environment. Climate change-related variables including increased ambient temperature, heat waves, extreme weather events, air pollution, and rainfall distribution, all can affect asthma in children, but each of these variables also affects asthma via alterations in pollen production and release, outdoor allergen exposure or the microbiome.

A 10-year comparative study of factors for allergic asthma and/or rhinitis in two cross-sectional surveys.

Background: The allergenic relevance of the living environment changes over the last decades is largely unknown.

Objective: We aimed to compare the factors associated with asthma and/or rhinitis between 2008 and 2018.

Methods: We assessed two nationally representative cross-sectional datasets in 2008 and 2018.

Decoding the neuroimmune axis in the atopic march: mechanisms and implications.

The immune and nervous systems have co-evolved complex mechanisms to sense environmental dangers and orchestrate a concerted response to safeguard tissue and mobilize host defenses. This sophisticated interplay, marked by a shared repertoire of receptors and ligands, influences disease pathogenesis. Neuro-immune interactions in allergic diseases are pivotal for symptom development, from anaphylaxis to chronic conditions like asthma and atopic dermatitis.
