McCann WA, Chipps BE, Beuther DA et al. Ann Allergy Asthma Immunol. 2026 Mar 22:S1081-1206(26)00120-1. doi: 10.1016/j.anai.2026.03.014. 

Abstract

Background

The Asthma Impairment and Risk Questionnaire (AIRQ) predicts 12-month exacerbation occurrence for patients aged ≥12 years.

Objective

To assess the short- and long-term exacerbation prediction ability of the AIRQ in patients with mild-to-moderate and severe asthma.

Methods

This post hoc analysis from the AIRQ longitudinal study classified patients with asthma aged ≥12 years as having mild-to-moderate or severe disease based on prescribed pharmacotherapy. Participant-reported severe asthma exacerbations were assessed monthly over 12 months. For both severity groups and relative to baseline AIRQ control category, exacerbation occurrence was assessed via logistic regression and Kaplan–Meier time-to-first event analyses for the overall 12-month period, months 0-3 (short-term), and months 4-12 (long-term) post-enrollment.

Results

Proportion of patients in the total population (A), with mild-to-moderate
(B) and severe asthma (C) who experienced ≥1 exacerbation over the
short-term (months 0-3) and long-term (months 4-12) follow-up periods
relative to AIRQ control category. AIRQ,
Asthma Impairment and Risk Questionnaire;

Of 1070 patients who completed ≥1 follow-up assessment, 374 (35.0%) had mild-to-moderate and 696 (65.0%) had severe asthma.

Enhanced Early Detection of Allergic Rhinitis: A Prospective Study on a Symptom-Based Predictive Model

K.-Z.Zhu, C.He, S.-Z.Zhu et al. World Journal of Otorhinolaryngology - Head and Neck Surgery 0 (2026): 1–12. https://doi.org/10.1002/wjo2.70109.

ABSTRACT

Introduction

Allergic rhinitis (AR) and non-allergic rhinitis (NAR) share overlapping symptoms but differ in pathophysiology and treatment. Current AR diagnosis relies on skin prick testing (SPT) and serum IgE quantification, both of which are complex. This study aimed to develop a symptom-based model for early AR detection, explore allergen-symptom relationships, and evaluate its performance.

Material and Methods

A prospective cohort study was conducted at Wuhan Tongji Hospital between June 2024 and October 2024, enrolling 1150 patients with clinically suspected AR. Participants completed a visual analogue scale (VAS) questionnaire evaluating nasal symptoms (itching, congestion, sneezing, rhinorrhea), ocular symptoms, and overall discomfort, and the final diagnosis of AR was confirmed by SPT.

Abstract

Allergic rhinitis (AR), driven by immune imbalance and excessive IgE production, manifests with symptoms that significantly impair the patient’s quality of life. Current therapies mainly provide symptomatic relief without correcting the underlying immune dysregulation. Bryostatin-1 (bryo-1) is a promising candidate for the causal treatment of AR. It potently inhibits IgE-mediated allergic responses while enhancing nasal mucosal defense through the selective induction of IgA antibodies upon intranasal administration. However, the intranasal delivery of bryo-1 faces challenges, including high cost, chemical instability, and limited permeability across the nasal mucosal barrier. In this study, bryo-1 was incorporated with liposomes with varying surface charges.

against antigens.

These LNPs exhibited stronger interactions with antigen-presenting cells and enhanced cellular uptake and delivery efficiency of bryo-1 in vitro. Notably, anionic LNPs achieved superior bryo-1 delivery to B cells, selectively promoting IgA class switching while suppressing IgE expression.

Olopatadine plus mometasone for seasonal allergic rhinitis treatment: A pooled analysis of clinical trials

Nakanishi M, Carbone LFB, Aggarwal V t al. Braz J Otorhinolaryngol. 2026 Apr 14;92(4):101817. doi: 10.1016/j.bjorl.2026.101817. 

Highlights

• First pooled analysis of Olopatadine/Mometasone FDC.

• Reinforces significant improvements compared to mometasone and olopatadine.

• Compiled safety data demonstrate low AEs and high adherence to treatment.

Abstract

Objective

This study was conducted to analyze the efficacy and safety of a fixed-dose combination of olopatadine HCl (antihistamine) and mometasone furoate (corticosteroid) (Olo/Mom, GSP301) for the treatment of Seasonal Allergic Rhinitis (SAR).

Methods

Efficacy data from one phase II (NCT02318303 [GSP301-201]) and two pivotal phase III double-blind, randomized, active, placebo-controlled (NCT02631551 [GSP301-301] and NCT02870205 [GSP301-304]) clinical trials were collated and analyzed. These studies investigated Olo/Mom (administered twice daily/BID) compared with placebo and its monotherapy constituents for the treatment of SAR in patients aged ≥12-years.

Treatment of allergic rhinitis with allergen immunotherapy in children and adolescents - Adherence, rhinitis severity, and asthma onset

Hedman AM, Lundholm C, Konradsen JR et al. Pediatr Allergy Immunol. 2026 Apr;37(4):e70304. doi: 10.1111/pai.70304.

Abstract

Background

Sublingual immunotherapy (SLIT) has been used to reduce symptoms in allergic rhinitis and to prevent asthma onset. Many studies lack level of adherence and standardized endpoints based on international guidelines.

Objective

We aimed to study the long-term outcomes of allergic rhinitis severity and asthma onset by adherence of SLIT to grass and birch allergens in children and adolescents with allergic rhinitis.

Methods

In a population-based register study, we included all children 5–17 years, with initiation of SLIT between 1 July 2006 and 30 June 2022. Allergic rhinitis severity and asthma onset were based on diagnosis and treatment. Adherence was measured for one, two, and 3 years and divided into low, moderate, and high and compared to only one prescription (reference).

Lipid metabolic regulation of pathogenic type 2 immunity in the airway

Hiroyuki Yagyu, Masahiro Kiuchi, Kiyoshi Hirahara.  International Immunology, 2026;, dxag015, https://doi.org/10.1093/intimm/dxag015

Abstract

IL-33-mediated activation of innate and adaptive type 2 immune cells.

Immune memory is central to host protection against pathogens and contributes to the pathogenesis of chronic inflammatory diseases. Beyond canonical cytokines and antigenic stimuli, metabolic signals have emerged as pivotal regulators of T-cell activation, differentiation, and memory formation. However, the mechanisms by which metabolic and tissue-derived cues imprint pathogenic features on T cells remain poorly understood.

Aesthetic interventions in patients with allergic skin diseases: Risk assessment and evidence-based preventive risk management

 

Yiğit İK, Türsen Ü, Türsen B et al. Clin Dermatol. 2026 Mar 13:S0738-081X(26)00060-X. doi: 10.1016/j.clindermatol.2026.03.001. 

Abstract

The use of aesthetic dermatologic procedures in patients with underlying allergic and inflammatory skin diseases is on the rise, but specific safety considerations are often overlooked. Individuals with hypersensitivity to injectables, chronic inducible urticaria, allergic contact dermatitis, atopic dermatitis, or hereditary angioedema may face an increased risk of adverse reactions triggered by mechanical trauma, injected substances, or disruption of the skin barrier.

Adverse reactions to local anesthetics are predominantly non-IgE-mediated. Thus, preventive strategies should focus on selecting the appropriate agents and employing proper injection techniques rather than routine pharmacologic prophylaxis. Botulinum toxin, hyaluronic acid fillers, and hyaluronidase can rarely cause immediate or delayed hypersensitivity reactions. This highlights the need for individualized risk assessment and avoidance of reexposure in confirmed cases. For patients with chronic inducible urticaria, aesthetic procedures can act as physical triggers.

Abstract

Diagnostic workflow for beta-lactam immediate hypersensitivity skin 

testing

Hypersensitivity to beta-lactams (BL) is the most frequent drug allergy, and skin testing (ST) remains the first-line diagnostic tool. Although generally safe, systemic reactions (SR) during ST are a concern. We conducted a 7-year ambispective study (2018–2025) including 216 adults with confirmed immediate hypersensitivity reactions (HSR) to BL, established by positive skin tests (ST) or drug challenge tests (DCT). Among them, 138 (63.9%) had positive ST, predominantly intradermal tests (IDT; 93.5%). Five patients (3.6% of ST-positive; 2.3% of the entire cohort) developed SR during ST, all after IDT following negative skin prick tests (SPT).
