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.

Evaluating the efficacy of a novel home-based oral food challenge protocol for pediatric food protein induced enterocolitis syndrome

Morris, E.G., Huan, P.W., Protudjer, J.L.P. et al.  Allergy Asthma Clin Immunol 21, 45 (2025). https://doi.org/10.1186/s13223-025-00994-z

Abstract

Background

Oral food challenges (OFCs) are considered the gold standard for diagnosis of food protein–induced enterocolitis syndrome (FPIES), a non-immunoglobulin E mediated gastrointestinal food allergy characterized by delayed, repetitive vomiting, lethargy, and sometimes diarrhea, primarily affecting infants and young children. Our modified approach to OFCs involves smaller, gradually increased doses to mitigate the risk of severe reactions. We aimed to measure the successful completion of this OFC protocol.

Methods

In a retrospective chart review, patients age < 18 years, who had 1 + episode of acute FPIES between 2015 and 2023 were identified using an allergy clinic database. Patients underwent OFCs with home up dosing every 2–4 weeks. Steps included 1%, 2%, 5%, 10%, 20%, 30%, 40%, 60%, 80%, and 100% of the final serving amount. The primary outcome was successful completion, i.e. absence of severe reactions during the OFC protocol and 1 year after.

Aldawas G, Bhat I N (October 28, 2025)  Cureus 17(10): e95631. doi:10.7759/cureus.95631

Abstract

Practical treatment algorithm for vasomotor rhinitis (VMR)

Vasomotor rhinitis (VMR) is a non-infectious, non-allergic subtype of rhinitis, which is characterized by nasal blockage, liquid runny rhinorrhea, and increased sensitivity to nonspecific nasal triggers (such as changing temperature and smell). Although VMR is a disease with a high prevalence rate, it is wrongly diagnosed and under-treated due to its clinical manifestation with allergic rhinitis. Databases such as PubMed, EMBASE, and Cochrane Library were searched to obtain articles published between 2000 and 2025. Randomized controlled trials, cohort studies, and major clinical guidelines were included, while case reports and non-English studies were excluded to ensure consistency and reproducibility of the findings. Existing evidence shows that multiple regulations of the autonomic nervous system, neuropathway neuroplasticity and inflammation, and excessive quantitative stimulation of transient receptor potential (TRP) channels all play a role in the pathophysiology of VMR. Variable therapies include corticosteroids, intranasal antihistamines, and anticholinergics, although ipratropium bromide has had the best dependability results in terms of rhinorrhea.

Efficacy comparison of combined montelukast-antihistamine and montelukast monotherapy in allergic rhinitis: a meta-analysis of randomized controlled trials

Kim JS, Stybayeva G, Hwang SH.  Eur Ann Allergy Clin Immunol. 2025 Oct 31. doi: 10.23822/EurAnnACI.1764-1489.420. 

SUMMARY

Background. Combination therapy with montelukast and oral antihistamines is commonly used in allergic rhinitis (AR), but its comparative benefit over montelukast monotherapy remains unclear. This meta-analysis aimed to evaluate the efficacy of combination therapy compared to monotherapy, with a focus on symptom-specific outcomes. 

Methods. A comprehensive search of PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases was conducted through April 2025. We systematically reviewed randomized controlled trials comparing montelukast combined with oral antihistamines to montelukast monotherapy in patients with AR. Outcomes included total symptom scores, Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores, and individual symptom domains. Pooled effects were analyzed using standardized mean differences (SMDs) with 95% confidence intervals (CIs). 

Direct comparison of changes in total symptom scores and
Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ)
scores between combination therapy and
montelukast monotherapy.

Results. Thirteen RCTs enrolling 2,950 patients were identified. Combination therapy significantly improved daytime symptoms (SMD = 0.25; 95%CI 0.15 to 0.35), with limited benefit for nighttime symptoms (SMD = 0.10; 95%CI -0.01 to 0.21) or RQLQ scores (SMD = 0.11; 95%CI -0.05 to 0.26). In subgroup analysis, all combinations with loratadine, desloratadine, or levocetirizine showed greater efficacy than monotherapy in improving daytime symptoms.

Cellular Stress, Inflammation and Barrier Damage in Gut Epithelial Cells Caused by Aspartame

Y. Pat, D. Yazici, C. Zeyneloglu, et al. Allergy (2025): 1–18, https://doi.org/10.1111/all.70095.

ABSTRACT

Graphical Abstract

Aspartame has been widely used as a sweetener in foods and beverages since the 1980s. In this study, we aimed to assess its effects on gut epithelial cell biology, inflammation and the epithelial barrier. We found that aspartame induces cytotoxic effects, disrupts the epithelial barrier and triggers proinflammatory cytokine release in gastrointestinal epithelial cells, organoids and gut-on-a-chip models at concentrations corresponding to daily consumed doses in food products. Cellular cytotoxicity was observed at doses as low as 1.25 mg/mL. RNA sequencing analysis revealed that aspartame significantly alters the transcriptome in gut-on-a-chip models, with upregulation of pathways involved in the unfolded protein response, pro-apoptotic and inflammatory processes and downregulation of those related to DNA repair and replication.

Updated Evidence for Covid-19, RSV, and Influenza Vaccines for 2025-2026

Scott J, Abers MS, Marwah HK et al. N Engl J Med. 2025 Oct 29. doi: 10.1056/NEJMsa2514268. 

Abstract

Background

Changes in the vaccine advisory process in the United States have disrupted immunization guidance, which reinforces the need for independent evidence review to inform decisions regarding immunization for respiratory viruses during the 2025–2026 season.

Methods

We conducted a systematic review of U.S.-licensed immunizations against coronavirus disease 2019 (Covid-19), respiratory syncytial virus (RSV), and influenza. We searched databases on PubMed/MEDLINE, Embase, and Web of Science for updates of the most recent review by the Advisory Committee on Immunization Practices (ACIP) Evidence-to-Recommendations for each disease, which was performed during the 2023–2024 period. Outcomes included vaccine efficacy and effectiveness against hospitalization, other clinical end points, and safety.

Results

Meta-Analysis of Vaccine Effectiveness
against Hospitalization for Covid-19

Of 17,263 identified references, 511 studies met the inclusion criteria. Covid-19 mRNA vaccines against the XBB.1.5 subvariant had pooled vaccine effectiveness against hospitalization of 46% (95% confidence interval [CI], 34 to 55; from cohort studies) and 50% (95% CI, 43 to 57; from case–control studies) among adults and 37% (95% CI, 29 to 44) among immunocompromised adults. In a case–control study, vaccines against the KP.2 subvariant showed an effectiveness of 68% (95% CI, 42 to 82).

An overview of published randomized, double-blind,
placebo-controlled Phase II/IIa/IIb trials of astegolimab

Abstract

Chronic inflammation is an underlying feature of respiratory diseases such as chronic obstructive pulmonary disease (COPD). Novel therapies that target the inflammatory mechanisms driving acute exacerbations of COPD are required. The ST2 receptor, which binds the alarmin interleukin (IL)-33 to initiate an inflammatory response, is a potential target. Astegolimab, a fully human immunoglobulin G2 monoclonal antibody, which binds with high affinity to ST2 to prevent binding of IL-33, is a potential therapy for COPD. However, targeting inflammatory pathways that form part of the immune system may have unintended consequences, such as implications for the response to infection and cardiovascular function. Therefore, an understanding of astegolimab’s safety profile in clinical use is essential.
This narrative review summarizes clinical safety data from published clinical trials of astegolimab with a focus on adverse events of interest, including infections and cardiac events.
