Pediatric asthma remains a prevalent and challenging chronic condition globally, affecting quality of life imposing significant burdens on families healthcare systems. Despite advancements in understanding pathophysiology treatment, key controversies persist optimizing management strategies. Inhaled corticosteroids (ICS) are the cornerstone reducing inflammation preventing exacerbations. While concerns about growth suppression exist, evidence suggests that this effect is primarily associated with high doses prolonged use, rather than standard maintenance therapy. Nonetheless, adherence to ICS suboptimal, necessitating strategies ensure effective sustained treatment. The introduction reliever therapy (MART) ICS–formoterol has offered improved outcomes by simplifying regimens reliance short-acting beta-agonists (SABA). However, supporting MART ICS-SABA younger children limited, highlighting gaps pediatric-focused research. Biologics targeting inflammatory pathways, such as omalizumab, mepolizumab, dupilumab, represent personalized approach for severe but face challenges including costs, limited long-term safety data, uncertainty regarding their ability modify disease progression. In addition, complexity treatment decisions compounded insufficient biomarkers age-specific guide Addressing these requires robust clinical studies tailored pediatric populations. This review critically examines current pharmacological strategies, unresolved issues, evolving approaches management, emphasizing need evidence-based care. Enhancing necessitates balancing therapeutic benefits minimal adverse effects leveraging ongoing research inform future practice.

Background: Atopic dermatitis (AD), allergic rhinitis (AR), and chronic rhinosinusitis with nasal polyps (CRSwNP) represent interconnected conditions within the spectrum of type 2 inflammatory diseases. While these share common genetic epigenetic pathways, precise molecular mechanisms remain underexplored. Methods: This review integrates latest insights on factors linking AD, AR, CRSwNP, focusing genome-wide association studies, DNA methylation patterns, histone modifications, microRNA regulation. Results: In all three conditions, including (Me) acetylation (Ac) methylation, regulate barrier-related genes, influencing disease severity. Notably, miRNAs such as miR-146a miR-155 play pivotal roles in modulating inflammation across diseases, while disease-specific contribute to airway remodeling (miR-125b miR-21 AR CRSwNP). Emerging evidence underscores role microbiome-driven inflammasome activation matrix metalloproteinases (MMP-2, MMP-9, MMP-12) perpetuating remodeling. Conclusions: The interplay between predispositions, exposomal systemic nature inflammation. A deeper understanding could lead transformative, personalized diagnostic therapeutic advancements.

Type 2-mediated immune responses protect the body against environmental threats at barrier surfaces, such as large parasites and toxins, facilitate repair of inflammatory tissue damage. However, maladaptive to typically nonpathogenic substances, commonly known allergens, can lead development allergic diseases. 2 immunity involves a series prototype TH2 cytokines (IL-4, IL-5, IL-13) alarmins (IL-33, TSLP) that promote generation adaptive CD4+ helper cells humoral products allergen-specific IgE. Mast basophils are integral players in this network, serving primary effectors IgE-mediated responses. These bind IgE via high-affinity receptors (FcεRI) expressed on their surface and, upon activation by release variety mediators regulate responses, attract modulate other cells, contribute repair. Here, we review biology effector mechanisms these focusing primarily role mediating both physiological pathological contexts.

Background: Food allergy (FA) poses a major global health issue due to the increasing prevalence and lack of effective prevention strategies. Allergen-specific immunotherapy (AIT) has emerged as disease-modifying therapy for FA. However, long-term treatment duration unexpected adverse reactions, only minority patients benefit from AIT. Therefore, prophylactic interventions are urgently needed FA patients. Methods: In this proof-of-concept study, using well-established mRNA platform, we developed vaccine candidates encoding egg white allergen Gal d2 comprehensively evaluated their efficacy against anaphylaxis in d2-induced allergic mouse model. Results: Two formulations, d2-IL-10 vaccine, both demonstrated potent ability inducing allergen-specific IgG Th1-type T cells. Importantly, two formulations showed promise preventing onset disease, which is indicated by body temperature decline during anaphylaxis. Conclusions: We provided preliminary evidence showing that platform unique holds development anti-allergy vaccines. This largely attributed capacities vaccines eliciting an allergen-blocking antibody, shifting Th2 towards Th1 immunity, well generating peripheral tolerance. further investigations required better understand mode action.

Allergic rhinitis (AR) is a common and increasingly prevalent chronic inflammatory disorder of the nasal mucosa that severely impacts patients’ quality life, causing symptoms like congestion, sneezing, itching. AR primarily mediated by immunoglobulin E (IgE) when allergens are present, making it challenging to manage despite available therapies pharmacotherapy, immunotherapy, surgery. Recently, research has focused on biologics as an emerging therapeutic option for AR. Biologics target specific immune pathways in type 2 inflammation, which underlies many allergic diseases including offer targeted potentially more effective alternative traditional therapies, addressing underlying mechanisms rather than simply alleviating symptoms. Based key clinical trial evidence, this paper tentatively proposes multidimensional strategy selecting AR, integrating serum IgE levels, disease phenotypes (seasonal/persistent), comorbid characteristics guide individualized treatment. However, long-term cost-effectiveness, optimal dosing regimens, patient adherence require further validation through real-world data. Despite these challenges, recent advancements represent promising step forward management. With ongoing trials, may soon provide lasting relief patients suffering from rhinitis.
