Introduction. Allergic rhinitis (AR) is one of the most frequent chronic diseases in the pediatric population; it affects the quality of life of children and their families, has economic impact, and is frequently underdiagnosed and undertreated. Given the scarcity of local data, here we describe the prevalence of AR and the clinical characteristics of the study population. Population and methods. Observational, cross-sectional study in patients younger than 19 years. Results. A total of 250 patients were randomly included; their mean age was 9 years (SD: 5). AR was diagnosed in 14 of them. The prevalence of AR was 6%. Conclusions. The prevalence of AR in our setting was 6%. AR should be given the relevance it deserves so as to provide an adequate diagnosis and treatment.

Augmented type 2 inflammatory response in allergic rhinitis patients experiencing systemic reactions to house dust mite subcutaneous immunotherapy.

BACKGROUND: Subcutaneous immunotherapy (SCIT) can induce systemic reactions (SRs) in certain patients, but the underlying mechanisms remain to be fully elucidated. METHODS: AR patients who were undergoing standardized HDM SCIT (Alutard, ALK) between 2018 and 2022 were screened. Those who experienced two consecutive SRs were included in the study group. A control group was established, matched 1:1 by gender, age, and disease duration with the study group, who did not experience SRs during SCIT. Clinical and immunological parameters were recorded and analyzed both before SCIT and after 1 year of treatment. RESULTS: A total of 161 patients were included, with 79 (49.07%) in the study group. The study group had a higher proportion of AR combined asthma (26.8% vs. 51.8%, p < 0.001) and higher levels of sIgE to HDM and HDM components (all p < .001). Serum IL-4 and IL-13 levels in the study group were higher than those in the control group (p < .05). The study group received a lower maintenance dosage of HDM extracts injections than control group due to SRs (50000SQ vs. 100000SQ, p < .05). After 1 year of SCIT, the VAS score, the lung function parameters of asthmatic patients over 14 years old significantly improved in both groups (all p < .05). After a 7-day exposure to 20 µg/mL HDM extracts, the percentages of Th1, Th17, Tfh10, and Th17.1 in PBMCs decreased, while the Tfh13 cells significantly increased in the study group (p < .05). CONCLUSION: The type 2 inflammatory response is augmented in HDM-induced AR patients who experienced SRs during SCIT. Despite this, SCIT remains effective in these patients when administered with low-dosage allergen extracts.

Changes in peripheral blood IL-9, Th9, and BAFF levels in patients with allergic rhinitis and their clinical implications.

BACKGROUND: Allergic Rhinitis (AR), a prevalent condition in otorhinolaryngology, is mediated by Type 1 hypersensitivity through IgE, characterized by Type 2 inflammatory response and eosinophil infiltration in the nasal mucosa. Since AR disease exhibits significant heterogeneity in symptom severity, an objective assessment of AR severity may facilitate better individualized treatment. OBJECTIVE: To explore the changes in peripheral blood IL-9, Th9, and BAFF levels of allergic rhinitis (AR) in patients and the clinical significance associated with it. METHODS: A retrospective study selected 80 AR patients admitted from January 2022 to October 2022 as the case group, dividing them into mild and moderate-to-severe groups based on symptom scores. Concurrently, 50 patients without AR, who were treated for nasal bone fractures or underwent septoplasty, were selected as the group for comparison. Alterations in the expression levels of peripheral blood IL-9, Th9, and BAFF were analyzed and compared among the different groups. The diagnostic value of serum BAFF for the severity of AR was analyzed using the receiver operating characteristic (ROC) curve. RESULTS: Noticeable variations were observed in clinical variables among the three groups such as, total IgE levels, peripheral blood eosinophil count and proportion, TNSS, and VAS (P< 0.05), while no statistically significant differences were observed in other variables (P> 0.05). The comparison of IL-9, Th9, and BAFF among the three groups revealed statistically significant differences (P< 0.05). Analysis using multivariate logistic regression revealed that IL-9 (OR = 2.365), Th9 (OR = 2.186), BAFF (OR = 2.307) were influencing factors of moderate-to-severe AR (P< 0.05). The ROC curve indicated that the AUC for the diagnosis of moderate-to-severe AR by IL-9, Th9, BAFF were 0.770, 0.734, 0.761, respectively, and the combined detection AUC was 0.888, an area under the curve higher than individual testing. CONCLUSION: Changes in peripheral blood IL-9, Th9, and BAFF levels in AR patients may function as indicators to assess the level of severity in diagnostic procedures.

The evidence for commercial house dust mite immunotherapy products: A pragmatic systematic review with narrative synthesis.

House dust mite (HDM) allergen immunotherapy (AIT) has an established role in the treatment of perennial allergic rhinitis (AR) and allergic asthma (AA) triggered by HDM sensitization. We aimed to identify all double-blind, randomized, placebo-controlled trials of HDM AIT for the treatment of AR and AA in humans and to summarize the evidence for AIT products that are currently manufactured and available for clinical use. A total of 56 eligible double-blind, randomized, placebo-controlled trials of HDM AIT for the treatment of AA and/or AR in humans fit the inclusion criteria and investigated a total of 14 commercial AIT products; together, the 56 studies enrolled a total of 14,619 patients. Of the 56 studies, 39 studies investigated the current manufacturer-recommended maintenance dose (MRMD) of the product, and 17 investigated other doses. We identified 39 studies (12,539 patients randomized) for 8 sublingual immunotherapy (SLIT) products and 17 studies (2,080 patients randomized) for subcutaneous immunotherapy products. For AR, 3 products, the ALK 12 standardized-quality (SQ-HDM) SLIT tablet, the ALK 6 SQ-HDM tablet, and the SG 300 index of reactivity SLIT tablet, had both dose-finding studies (DFSs) and phase III definitive studies (DSs) to demonstrate efficacy of the MRMD of the product. For AA, 2 products, the ALK 12 SQ-HDM SLIT tablet and the ALK 6 SQ-HDM tablet, had both DFSs and DSs for the MRMD. No subcutaneous immunotherapy product had a paired DFS and DS supporting the MRMD. A total of 30 studies of products no longer commercially manufactured were excluded. This study will help to inform clinical care and product selection for the treatment of HDM-induced AR and AA.

Endoplasmic Reticulum Stress Promotes Telomerase Reverse Transcriptase Expression Contributes to Development of Allergic Rhinitis.

BACKGROUND: The Th2 cell polarization is a crucial factor in the pathogenesis of allergic diseases. The underlying mechanism requires further investigation. Telomerase has an immune-regulating ability. The aim of this study is to elucidate the association between telomerase and Th2 cell polarization in patients with allergic rhinitis (AR). METHODS: CD4+ T cells were isolated from blood samples collected from AR patients and healthy control subjects. RNA sequencing was employed to analyze RNA samples extracted from CD4+ T cells. An AR mouse model was established using the ovalbumin-alum protocol. RESULTS: High telomerase gene activity and high endoplasmic reticulum (ER) stress status were observed in CD4+ T-cells in patients with AR. Positive correlation between the telomerase reverse transcriptase (TERT) gene expression in CD4+ T cells and AR response in patients with AR. TERT facilitated the degradation of Foxp3 proteins in CD4+ T cells, resulting in the polarization of Th2 cells. Sensitization with the ovalbumin-alum protocol enhanced the Tert expression in CD4+ T cells by exacerbating ER stress. Conditional inhibition of the Tert or eukaryotic translation initiation factor 2-α (Eif2a) expression in CD4+ T cells effectively attenuated experimental AR in mice. CONCLUSIONS: Elevated amounts of telomerase in CD4+ T cells were found in CD4+ T cells of subjects with AR. Telomerase promoted Th2 cell polarization by inducing Foxp3 protein degradation and promotes GATA3 activation. Inhibition of TERT or eIF2a alleviated experimental AR.

The Evaluation Value of the Modified Lund-Kennedy Nasal Endoscopy Score on the Efficacy of Sublingual Immunotherapy for Allergic Rhinitis.

OBJECTIVE: Allergic rhinitis (AR) is a growing public health problem worldwide. Respecting the significance of the modified Lund-Kennedy (MLK) score in rhinitis assessment, we delved into its evaluation value on the sublingual immunotherapy (SLIT) efficacy in AR patients. METHODS: Totally 100 AR patients were enrolled, with pre- and post-SLIT MLK score, total nasal symptoms score (TNSS), total medication score (TMS), visual analogue scale (VAS), inflammatory cytokines, and immune function-related parameters compared. The correlations of MLK score with TNSS/TMS/VAS, as well as with IL-4/INF-γ/eosinophil (EOS)/percentage/specific immunoglobulin (sIgE)/sIgG were assessed by Spearman correlation analysis. The value of MLK score on assessing SLIT efficacy in AR patients was analyzed. RESULTS: SLIT treatment reduced MLK/TNSS/TMS/VAS scores, abated IL-4 level/EOS percentage/sIgE, and elevated INF-γ/sIgG levels. MLK score was positively correlated with pre- and post-SLIT TNSS score (rpre-treatment = 0.592, rpost-treatment = 0.756), TMS score (rpre-treatment = 0.385, rpost-treatment = 0.718), VAS score (rpre-treatment = 0.369, rpost-treatment = 0.704), IL-4 (rpre-treatment = 0.553, rpost-treatment = 0.639), EOS percentage (rpre-treatment = 0.511, rpost-treatment = 0.632), and sIgE (rpre-treatment = 0.472, rpost-treatment = 0.524), and negatively with INF-γ (rpre-treatment = -0.418, rpost-treatment = -0.578) and sIgG4 (rpre-treatment = -0.460, rpost-treatment = -0.613). The MLK score had an area under curve of 0.846 (77.01% sensitivity, 76.92% specificity, 4 cut-off value) and 0.944 (91.67% sensitivity, 92.11% specificity, 2 cut-off value) for assessing SLIT treatment as effective and markedly effective for the patients, respectively. CONCLUSION: The MLK score had good evaluation value on the efficacy of SLIT treatment in AR patients.

Degree of fear of needles and preferred allergy immunotherapy treatment among children with allergic rhinitis: caregiver survey results.

Introduction: A child's fear of needles may impact the preferred route of allergy immunotherapy (AIT) when choosing between subcutaneous immunotherapy (allergy shots) or sublingual immunotherapy (SLIT). A survey was conducted to understand caregiver health-seeking behavior for children with allergic rhinitis with or without conjunctivitis (AR/C) and explore if fear of needles impacted AIT decisions. Methods: Caregivers of children ages 5-17 years with AR/C were recruited from the Dynata US research panel to participate in an online survey from May-June 2023. The survey received institutional review board exemption status. SLIT-tablets were described as "under-the-tongue tablets". Results: About a third (34%) of surveyed caregivers (n = 437) reported their child had a severe fear of needles and 47% reported moderate fear. Of surveyed caregivers, 53% and 43% reported they had discussed allergy shots and SLIT-tablets, respectively, with their child's physician. SLIT-tablets were preferred by 84% of caregivers; 6% preferred injections and 10% had no preference. Caregivers of children with a severe fear of needles had the highest preference for SLIT-tablets (95%) vs. injections (2%); 85% and 60% of caregivers of children with moderate and low fear, respectively, preferred SLIT-tablets. Among caregivers of children with a severe fear of needles, a higher percentage agreed that their child would welcome taking SLIT-tablets than that their child would accept taking an ongoing series of allergy shots (93% vs. 43%, respectively). Conclusions: Most caregivers preferred SLIT-tablets over allergy shots for their child with AR/C. Preference for SLIT-tablets corresponded with the child's degree of fear of needles. Fear of needles should be included in AIT shared decision-making conversations.

Blood and local eosinophil levels in chronic rhinitis: Observations during seasonal allergen exposure and non-exposure.

Background: Allergic rhinitis (AR) is a typical type 2 inflammatory disease and eosinophils play a critical role of cardinal effectors in type 2 inflammation. However, the distribution of eosinophils in patients with different subtypes of rhinitis and the effect of allergen exposure on them remain understudied. The aim of this study was to investigate the characteristics and factors influencing the distribution of systemic and local eosinophils in patients with non-AR (NAR), perennial AR (PAR), and seasonal AR (SAR), as well as the effect of seasonal allergen exposure levels on eosinophils. Methods: This was a population-based, cross-sectional observational study of consecutive chronic rhinitis (CR) outpatients who volunteered to participate in the survey during the spring pollen season and non-pollen season of 2023 in Beijing. All participants underwent serum allergen testing, blood routine examination, and nasal secretion smear cytology, and completed questionnaires mainly involving basic information, history review, and symptom assessment. Spring pollen dispersal concentration were considered. Results: A total of 558 CR patients eligible for enrollment were collected, including 198 NAR, 204 PAR, and 156 SAR patients. PAR had the highest blood eosinophil levels and the most severe overall nasal and ocular symptoms of SAR. Compared with subjects with blood eosinophil counts <0.3 × 109/L, those with ≥0.3 × 109/L had significantly more severe nasal and ocular symptoms and a significantly higher rate of comorbid asthma and allergic conjunctivitis. Blood eosinophil levels were significantly higher in SAR patients during the pollen season compared to the non-pollen season, and pollen concentrations were positively correlated with systemic and local eosinophil levels. Conclusions: Blood eosinophil levels varied in patients with different subtypes of rhinitis. Patients with high blood eosinophil levels had more severe overall nasal and ocular symptoms, and that blood eosinophils levels were significantly higher in patients with asthma or allergic conjunctivitis than patients without comorbidities. There was a positive trend between allergen exposure and systemic and local eosinophil levels. Further longitudinal cohort studies are still needed to better analyze the influence of eosinophil levels on the clinical traits of AR.

Development and Psychometric Evaluation of the Hope in Medicine Scale.

Background: Hope is an integral, multi-dimensional part of seeking medical treatment. The aim of this study was to develop a self-report scale, the Hope in Medicine (HIM) scale, to measure different modes of hoping in relation to the course of symptoms, the effects of treatment, and supporting medical research. Method: We examined the psychometric properties of the scale in a sample of 74 allergic rhinitis patients participating in a 2-week randomized-controlled trial comparing open-label placebos (OLP) with treatment as usual (TAU). Results: The HIM scale had a Cronbach's α of .78. An exploratory factor analysis revealed four factors: realistic hope (i.e., hoping for specific positive outcomes such as improvement in symptoms), transcendent hope (i.e., non-directed hoping that things will turn out positively), utopian hope (i.e., hoping to contribute to greater knowledge), and technoscience hope (i.e., hoping for scientific breakthroughs). Speaking to the convergent validity of the scale, realistic hope was moderately related to treatment expectancies (r = .54); transcendent hope was related to optimism (r = .50), treatment expectancies (r = .37), self-efficacy (r = .36), and inversely correlated with pessimism (r = -.43). Hope subscales predicted neither course of symptoms nor impairment. Conclusion: The HIM scale is a questionnaire with adequate internal consistency allowing to assess four modes of hoping. Preliminary results for its convergent validity are promising. Yet, further validation is needed.

Identification of ENTPD1 as a novel biomarker linking allergic rhinitis and systemic lupus erythematosus.

Several studies reveal that allergic rhinitis (AR) is a significant risk factor of systemic lupus erythematosus (SLE). However, studies investigating the common pathogenesis linking AR and SLE are lacking. Our study aims to search for the shared biomarkers and mechanisms that may provide new therapeutic targets for preventing AR from developing SLE. GSE50223 for AR and GSE103760 for SLE were downloaded from the Gene Expression Omnibus (GEO) database to screen differentially expressed genes (DEGs). The Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to explore the functions of shared DEGs. Hub genes were screened by cytoHubba (a plugin of Cytoscape) and validated in another two datasets. Gene set enrichment analysis (GSEA) and single-sample Gene set enrichment analysis (ssGSEA) algorithm were applied to understand the functions of hub gene. ENTPD1 was validated as a hub gene between AR and SLE. GSEA results revealed that ENTPD1 was associated with KRAS_SIGNALING_UP pathway in AR and related to HYPOXIA, TGF_BETA_SIGNALING and TNFA_SIGNALING_VIA_NFKB pathways in SLE. The expression of ENTPD1 was positively correlated with activated CD8 T cell in both diseases. Thus, ENTPD1 may be a novel therapeutic target for preventing AR from developing SLE.

Prenatal heavy metal exposure and pediatric asthma, allergic rhinitis, atopic dermatitis: a systematic review and meta-analysis.

OBJECTIVE: We review the prevalence of allergic diseases in children across prenatal exposures to heavy metals. METHODS: This systematic review and meta-analysis is registered in the PROSPERO database (CRD42023478471). A comprehensive search of PubMed, Web of Science, Medline and Cochrane library was conducted from the database inception until 31 October 2023. The Newcastle-Ottawa Quality Assessment Scale (NOS) was used to assess the quality of included studies. We used a random-effects model to summarize the effects from the studies. RESULTS: A total of 16 studies were included, 120,065 mother-child pairs enrolled. The NOS scores indicated that the quality of the literature included in the study was of a high standard. CONCLUSION: The final results indicate that prenatal exposure to Pb increased the incidence of wheeze and Eczema in infants, and exposure to Ni and CD increased the incidence of AD in infants.

Unraveling the Molecular Threads: A Comprehensive Review of the Pathogenesis and Therapeutic Insights Into Allergic Rhinitis.

Allergic rhinitis (AR) is a prevalent inflammatory disorder of the nasal mucosa, triggered by allergen exposure and characterized by symptoms such as sneezing, nasal congestion, itching, and rhinorrhea. This comprehensive review aims to unravel the molecular mechanisms underpinning AR, exploring the pathogenesis from allergen recognition to chronic inflammation and tissue remodelling. Central to the disease are immunoglobulin E (IgE)-mediated hypersensitivity reactions, involving key inflammatory mediators and cellular players such as mast cells, eosinophils, and T cells. Genetic predisposition and environmental factors also play significant roles in susceptibility and disease progression. Therapeutic strategies for AR are varied, ranging from symptomatic relief through antihistamines and nasal corticosteroids to more targeted approaches like allergen-specific immunotherapy. Emerging treatments focus on novel molecular pathways, with a growing emphasis on personalized medicine to optimize patient outcomes. Despite advancements, challenges remain in fully understanding the heterogeneity of AR and developing universally effective treatments. This review synthesizes current knowledge, highlighting critical insights into the molecular basis of AR and their implications for clinical practice. It underscores the need for integrated, multidisciplinary approaches to enhance therapeutic efficacy and calls for ongoing research to address unresolved questions and explore new frontiers in AR management. Through this comprehensive synthesis, the review aims to inform and inspire future research and clinical strategies, ultimately improving the quality of life for individuals affected by AR.

Changes in Skin Test Aeroallergen Sensitization in Mexico Over the Past 14 Years and According to Climate.

Introduction: Aeroallergen exposure has an intra- and extra-domiciliary component and varies according to climatological zones. Mexico is a large country with a great variety of climates. A previous study (2009) evaluated skin prick test results (SPT) in different regions. In this study, we compare previous sensitization patterns from 14y ago with current ones and compare them between different climatological zones. Methods: Mexican allergists were asked to share their last 100 SPT results in patients with respiratory allergy. Clinics were grouped in (semi)humid vs (semi)dry zones. Results were analyzed nationwide and compared to the 2009 results, calculating odds ratio (OR) and 95% confidence intervals (95% CIs), with p <0.05 as cut-off. Similarly, we compared (semi)humid versus dry zones. Results: We collected 2915 SPT results from 28 clinics (19 cities). Dermatophagoides was the most frequently sensitizing allergen. There was a significant increase in SPT positivity from 2009 to 2023 in both in- and outdoor aeroallergens (OR 1.26-2.65, 95% CI from 1.06-1.50 to 1.99-3.52). Comparing dry-humid zones, sensitization to pollen from Oleaceae, Fagaceae (p < 0.0001 all) and most weeds is more frequent in humid zones, as are Dermatophagoides and cockroach (both p < 0.0001). Eucalyptus, mesquite, and all grass pollen sensitizations predominate in dry zones (p < 0.05-0.0001). There are no differences in sensitization to cat or dog between zones. Conclusion: We found a general increase in SPT sensitization over the past fourteen years, suggesting that this is probably not only due to climate change. The different sensitization profile throughout the country was mainly related to humidity. Repeating epidemiologic SPT studies over the years could help tracking changes in allergen sensitization over time.

Genetically predicted allergic rhinitis causally increases the risk of erectile dysfunction.

Objective: Evidence shows that allergic rhinitis (AR) may increase the risk of erectile dysfunction (ED). This study aims to investigate whether there is a causal relationship between AAR and ED by Mendelian randomization (MR) analysis. Methods: We performed a two-sample MR analysis using genome-wide association studies (GWAS) summary data. Single nucleotide polymorphisms (SNPs) associated with AR and ED were obtained from the GWAS database. The MR analysis primarily employed the inverse variance weighted (IVW), MR Egger, and weighted median (WM) methods. We assessed pleiotropy using the MR-PRESSO global test and MR-Egger regression. Cochran's Q test was used to evaluate heterogeneity, and a leave-one-out analysis was performed to verify the robustness and reliability of the results. Results: The IVW analysis demonstrated a positive association between genetic susceptibility to AR and an elevated relative risk of ED (IVW OR = 1.40, p = 0.01, 95% CI 1.08-1.80). The results obtained from MR-Egger regression and WM methods exhibited a consistent trend with the results of the IVW method. Sensitivity analyses showed no evidence of heterogeneity nor horizontal pleiotropy. The leave-one-out analysis showed that the findings remained robust and were unaffected by any instrumental variables. Conclusion: This study presents genetic evidence that indicates a causal association between AR and ED.

Recent prevalence of allergic rhinitis caused by house dust mites among the pediatric population in Fukui, Japan.

Background: Allergic rhinitis (AR) is an IgE-mediated type I allergic chronic nasal disease common among all age groups, including the pediatric population. House dust mites (HDMs) are globally ubiquitous and the most important indoor aeroallergen. However, the recent prevalence of HDM-caused AR (AR-HDM) in Japan remains unknown, especially after the COVID-19 pandemic. Objective: The objective of this study was to investigate the current prevalence of AR-HDM, its clinical features, and the current status of medical examinations in elementary school students. Methods: A survey of 41,000 elementary school students was conducted during July 2021 in Fukui Prefecture, Japan. Parents were asked to complete a questionnaire that examined allergic disease history and clinical background. Results: A total of 17,974 subjects were analyzed in the study. The results showed that the current prevalence of AR-HDM in elementary school children is 18.8%. We found that AR-HDM had already developed before entrance into elementary school in 68.3% of affected subjects. Among these subjects, 82.3% had received some form of treatment, such as prescription medications, whereas 4.2% were treated by allergen immunotherapy. Multiple logistic regression analysis of the onset of AR-HDM revealed that male sex, being the first-born child, comorbidity of bronchial asthma, atopic dermatitis, food allergy, and allergic conjunctivitis are associated with development of AR-HDM. Conclusions: The present study revealed the prevalence of AR-HDM in elementary school children. The results emphasize the importance of appropriate diagnosis and treatment from infancy through early childhood.

[The role of ozone in the pathogenesis of allergic rhinitis].

Allergic rhinitis （AR） is a nasal hypersensitivity disease that is influenced by environmental factors, genetic factors, and various inflammatory factors. The role and mechanisms of ozone, as a component of air pollution, in the pathogenesis of AR are not yet fully understood. This article provides a review of the impact of ozone on the epidemiology and pathology of AR, as well as its possible mechanisms, to provide new insights into the prevention and treatment of AR.

Self-management and information needs of adults with seasonal allergic rhinitis in the Netherlands: A focus group study.

This focus group study explored the needs, preferences and beliefs of adults with seasonal allergic rhinitis regarding their self-management practices, and related information use and needs. Four focus groups were held, two online and two on location. The 20 participants (11 women); Mage = 39.0 years (range: 21-56 years) were reluctant to identify themselves as patients, trivializing their complaints while avoiding being confronted too much with their condition. Participants often expressed low trust in the effectiveness of medication and the ability of healthcare to alleviate their complaints. This resulted in relatively low openness to information such as personalized pollen predictions. Findings were synthesized under three interrelated themes: 'Being ill, but not a patient: it's bad, but you learn to live with it', 'Individual search for what does or doesn't work' and 'Information needs and sources'. Implications for communication supportive of self-management practices for seasonal allergic rhinitis are discussed.
