Graphical Abstract

ABSTRACT

Background

Dupilumab is effective in treating patients with type-2 dominant chronic rhinosinusitis with nasal polyps (T2-CRSwNP). Dosing starts at an interval of 1×/2 weeks (Q2W) with possible tapering upon disease control. Prolonging the interdose interval reduces patient burden and side effects and improves cost-effectiveness.

Objectives

(1) Analyze how many patients successfully reach and maintain extended tapering of at least 1×/12 weeks (Q12W), (2) evaluate differences in baseline characteristics and clinical measurements between patients who maintain disease control on ≥ Q12W (“super-responders”) and patients who do not; (3) compare characteristics of “super-responders” to patients reaching Q12W but losing disease control on that dose (“excellent responders”).

Key Predictors of Adherence to a Mobile Health App for Managing Chronic Spontaneous Urticaria

Viegas H, Sousa-Pinto B, Vieira RJ, et al. Clin Transl Allergy. 2025 Nov;15(11):e70110. doi: 10.1002/clt2.70110.

ABSTRACT

Background

Mobile health technologies may improve the management of chronic diseases, such as chronic spontaneous urticaria. However, effectiveness of mHealth tools largely depends on patient adherence, which can be influenced by various demographic, clinical, behavioural, psychosocial factors, and apps characteristics (appealing and simplicity of use). Understanding these adherence patterns is crucial for optimizing mHealth interventions. In this study, we aimed to assess adherence patterns associated to the use of CRUSE, a mHealth app designed for patients with CSU.

Methods

We assessed users of the CRUSE app with self-reported CSU or suggested by a physician. For each user, we evaluated the number of days they completed the CRUSE daily monitoring questionnaire (app adherence) within the first 3 months after installation. We constructed univariable and multivariable ordered beta regression models to identify predictors of 3-month adherence to the app.

Results

to include in multivariable models

We analysed data from 2085 patients (66,114 days). Median adherence to the CRUSE app was of 22 days (24.4% of 90 days).

Evaluation of the relationship between multiple inflammatory markers, disease severity and antihistamine response in chronic spontaneous urticaria

Atik Ö, Can A.  Alergologia Polska - Polish Journal of Allergology. 2025. doi:10.5114/pja.2025.156073.

Introduction

Chronic spontaneous urticaria (CSU) is a skin condition marked by excessive immune system inflammation. The C-reactive protein (CRP)/albumin ratio (CAR), neutrophil/lymphocyte ratio (NLR), eosinophil/neutrophil ratio (ENR), and eosinophil/lymphocyte ratio (ELR) are recent biomarkers that indicate systemic inflammation.

Aim

This study aims to examine the role of these inflammatory markers in assessing the severity of CSU and predicting the response to antihistamine treatment.

Material and methods

The study included 246 CSU patients from our outpatient clinic.

Transepidermal Water Loss in Oral Food Challenges in Children With Peanut Allergy. A Randomized Clinical Trial

Freigeh GE, O’Shea KM, Troost JP et al JAMA Netw Open. 2025;8(11):e2543371. doi:10.1001/jamanetworkopen.2025.43371

Key Points

• Question  Can transepidermal water loss (TEWL) as a measure of skin barrier function be used to reduce anaphylaxis rates and severity during oral food challenges in children with peanut allergy?
• Findings  In this randomized clinical trial that included 40 children aged 6 months to 5 years with peanut allergy, the anaphylaxis rate among participants with an allergic reaction during a peanut oral food challenge was lower in the group for which TEWL was used as a stopping criterion (63%) than in the control group (100%).
• Meaning  The findings suggest TEWL can augment anaphylaxis prediction during oral food challenges.

Abstract

Visual Abstract.

Importance  Food allergy is a prevalent chronic medical condition in children, with limited diagnostic options. Transepidermal water loss (TEWL) is a measure of skin barrier function with emerging utility in atopy and food allergy.

Objective  To determine whether use of TEWL as a stopping criterion can prevent anaphylaxis during a peanut oral food challenge (OFC).

Design, Setting, and Participants  This was a single-center randomized clinical trial of children aged 6 months to 5 years with a history of a clinical peanut allergic reaction and positive peanut skin prick and/or serum immunoglobulin E testing.

Exploring the Disease Duration of Urticaria and Associated Determinants in Primary Care

R. Soegiharto, B. J. Hengevelt, N. Boekema-Bakker, et al.  Clinical & Experimental Allergy (2025): 1–4, https://doi.org/10.1111/cea.70170.

Summary

• Most patients (75%) with new-onset urticaria in general practice recover within 1 week.
• Chronic urticaria (17%) was associated with higher age at onset, high BMI and early prednisolone prescriptions, the latter likely reflecting higher disease severity.

Determinants of longer disease duration.

To the editor,

Most patients presenting with new-onset urticaria are expected to have short-lived symptoms, acute urticaria (AU). Initial treatment of urticaria is therefore generally limited to a wait-and-see approach and second-generation (low dose) H1-anthistamines [1]. However, it is estimated that 0%–39% of patients develop chronic urticaria (CU), mainly based on outdated studies that focused on children with a follow-up time of up to 2 years [2]. Determining the exact proportion of CU patients is essential, because...

REAL WORLD DATA ON THE EFFECTIVENESS OF EPINEPHRINE NASAL SPRAY IN CLINICAL PRACTICE-UPDATE

Casale, T. et al. Annals of Allergy, Asthma & Immunology, Volume 135, Issue 5, S2

Abstract

Introduction

Intranasal epinephrine spray 2 mg (IN) is the first FDA-approved needle-free epinephrine product for the treatment of severe allergic reactions, including anaphylaxis. Intranasal epinephrine efficacy and safety are supported by extensive pharmacokinetic and pharmacodynamic data, a Phase 3 study in Oral Food Challenge (OFC) patients, and a series of case reports. To evaluate “real world” performance, health care providers (HCP) were surveyed regarding treatment outcomes following IN use.

Methods

Product was provided through an experience program to HCPs for use in their clinics and were surveyed regarding 1) the number of patients dosed; 2) the number of patients requiring a second dose of epinephrine to treat their allergic reactions; and 3) ease of use on a scale of 1-7. Data was collected by the company.

Associations between reservoir bedroom dust allergen levels and sleep symptoms in school-age children

Gueye-Ndiaye S, Wang Y, Wang J et al.  Sleep Health 2025 Nov 4:S2352-7218(25)00215-3. doi: 10.1016/j.sleh.2025.09.007.

Abstract

Objectives

Exposure to allergens may trigger inflammatory pathways contributing to poor sleep. We investigated the associations between indoor allergen concentrations with multiple sleep dimensions in children.

Methods

Bedroom dust aeroallergens were collected in participants' homes. The outcomes were caregiver-reported sleep-related daytime impairment and sleep disturbance (pediatric PROMIS instruments), sleep-disordered breathing (SDB; apnea-hypopnea index or oxygen desaturation index >5), and actigraphy-based short sleep (<8 hours) duration and poor sleep continuity (sleep fragmentation index > 75th percentile).

Background

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus that effects both pediatrics and adult patients in Canada and is increasing in prevalence. No Canadian focused best practice recommendations currently exist to guide clinical practice.

Methods

The study used a modified Delphi technique to develop evidence and expert opinion-based recommendations for providing care for patients with EoE. The Delphi process consisted of 3 rounds of quantitative surveys and qualitative consensus meetings.
