Allergic Rhinits

OBJECTIVES: The aim of this study was to explore the differences in the pattern of allergen sensitization in CR individuals without or with asthma, according to asthma severity. METHODS: A total of 1066 adults were evaluated. Asthma and chronic⁄allergic rhinits were identified by specialists, questionnaries and skin-prick test. The phenotypic characterization was avaliable from skin-prick test to an aeroallergen extended panel, total IgE and pulmonary function...

In Switzerland, almost 20 % of the population suffers from allergic rhinitis, which has a major impact on patients' quality of life. Allergen avoidance remains the most effective measure but is not always possible. Intranasal corticosteroids, oral antihistamines, or combination of intranasal corticosteroids and antihistamines remain first-line pharmacological treatments. In case of refractory symptoms, despite well-managed symptomatic treatment, when the patient wishes a more long-term effect or for prevention of asthma, the patient can be referred to the allergologist for specific immunotherapy...

BACKGROUND: Etiology of allergic rhinitis and asthma is frequently associated with house dust mite sensitization and allergen immunotherapy (AIT) represents the only disease modifying treatment. In a real world setting, clinicians would benefit from biomarkers to monitor or predict response to AIT. METHODS: Twenty-four consecutive house dust mite (HDM) mono-sensitized rhinitic patients, treated with subcutaneous immunotherapy (SCIT) as per clinical practice, were enrolled...

Allergic rhinitis and asthma are major public health concerns and economic burdens worldwide. However, little is known about nasal bacteriome dysbiosis during allergic rhinitis, alone or associated with asthma comorbidity. To address this knowledge gap we applied 16S rRNA high-throughput sequencing to 347 nasal samples from participants with asthma (AS = 12), allergic rhinitis (AR = 53), allergic rhinitis with asthma (ARAS = 183) and healthy controls (CT = 99). One to three of the most abundant phyla, and five to seven of the dominant genera differed significantly ( p < 0...

INTRODUCTION: The contribution of dietary patterns in the occurrence of atopic diseases, mainly asthma, allergic rhinits, and eczema is ambiguous. Our study examined the association between the level of adherence to the Mediterranean diet (MedDiet) and the prevalence of atopic diseases in adolescence. METHODS: A total of 1934 adolescents (boys: 47.5%, mean age [standard variation]: 12.7[0.6] years) enrolled voluntarily. Participants completed a validated questionnaire on atopic disease status, dietary habits, and other sociodemographic and lifestyle characteristics...

Allergic rhinitis and asthma are the most common causes of chronic inflammation of the upper and lower airways in childhood. However, a nasal biomarker that can link to pulmonary inflammation is yet to be found. The present paper aims to investigate the possible role in inflammation of two inducible 70-kDa Heat Shock Proteins (HSP70) members, HSPA1A/B and HSPA6, in nasal mucosa cells of allergic children through their mRNA expression analysis, and their correlation to both spirometric and FeNO values. The relationship between FeNO in lower airways and ∆Cts of HSPA1A/B in nasal mucosa seems to be influenced by clinical symptoms regardless of age, sex, and sensitization patterns...

OBJECTIVE: Placebos being prescribed with full honesty and disclosure (i.e., open-label placebo = OLP) have been shown to reduce symptom burden in a variety of conditions. With regard to allergic rhinits, previous research provided inconclusive evidence for the effects of OLP, possibly related to a separate focus on either symptom severity or symptom frequency. Overcoming this limitation of previous research, the present study aimed to examine the effects of OLP on both the severity and frequency of allergic symptoms...

Data obtained from controlled clinical trials are the gold standard for evaluation of allergen immunotherapy (AIT) efficacy and safety. Less prone to biases (with a strong internal validity), they allow their use and external validation in the real world. The quantity and diversity of real-world data has increased exponentially, and access to large cohorts and electronic medical records have made this information increasingly accessible and useful for research and regulatory purposes. New retrospective database studies have confirmed the sustained benefits of grass, birch pollen, and house dust mite AIT for both allergic rhinitis and asthma symptom and medication scores, the prevention of asthma (when used in nonasthmatic rhinitics), and the real rate of adverse systemic reactions...

The identification of allergens is essential in the management of allergic rhinitis. Sugarcane produces anemophilic pollen. The purpose of our study is to assess the role of sugarcane pollen in the occurrence of allergic rhinitis. We conducted a case-control analytical study of patients living in a Malagasy rural commune in which sugarcane cultivation and processing are important sources of employment, from July 2017 to June 2018. We enrolled 182 patients (91 cases and 91 controls). Factors associated with the occurrence of symptoms of allergic rhinitis were: a distance of less than 500 meters between homes and sugarcane fields (OR = 1...

INTRODUCTION: Although rhinitis is among the most common diseases worldwide, rhinitis prevalence in the general adult population is unclear and definitions differ widely. OBJECTIVE: To summarize the literature on rhinitis prevalence in the general adult population and to assess: (1) the prevalence according to different rhinitis definitions overall and in different regions of the world, and (2) the evolution of rhinitis prevalence over time. METHODS: We conducted an extensive literature review of publications including rhinitis prevalence using Pubmed and Scopus databases up to October 2020...

BACKGROUND: Viral infections, especially those caused by rhinovirus, are the most common cause of asthma exacerbations. Previous studies have argued that impaired innate antiviral immunity and, as a consequence, more severe infections contribute to these exacerbations. OBJECTIVE: These studies explored the innate immune response in the upper airway of volunteers with allergic rhinitis and asthma in comparison to healthy controls and interrogated how these differences corresponded to severity of infection...

BACKGROUND: House dust mite (HDM)-induced allergic rhinitis (AR) is a highly prevalent disease with bothersome symptoms. Genetic variants of the Hippo pathway genes play a critical role in the respiratory disease. However, no study has reported associations between variants of the Hippo pathway genes and HDM-induced AR risk. METHODS: Forty-three key genes in the Hippo pathway were selected from the Kyoto Encyclopedia of Genes and Genomes (KEGG), Reactome pathway database, and previous reported studies...

BACKGROUND: Allergic rhinitis is characterized by rhinorrhea, nasal congestion, sneezing and nasal pruritis. Group 2 innate lymphoid cells (ILC2s), CD4+ T cells and eosinophils in nasal mucosa are increased significantly after nasal allergen challenge (NAC). Effects of intranasal corticosteroids (INCS) on ILC2s remains to be investigated. METHODS: Subjects (n=10) with allergic rhinitis and mild asthma were enrolled in a single-blind, placebo-controlled, sequential treatment study and treated twice daily with intranasaltriamcinolone acetonide(220µg) or placebo for 14 days,separated by a 7-day washout period...

BACKGROUND: Rhinologists often encounter a broad spectrum of allergic rhinitis (AR) and nonallergic rhinitis (NAR) patients, who can be variably classified based upon timing and severity of disease. Our understanding of the varied quality of life (QOL) impact in different classifications of rhinitis is limited. Thus a more comprehensive understanding of the impact of rhinitis upon our patients, as measured by both patient reported outcome measures (PROMs) and clinical physiologic measures, as well as unique factors associated with disease severity is needed...

Adolescence is one of the most rapid phases of human development, in which biological maturity precedes psychosocial maturity. Rhinoconjunctivitis (ARC) is present in around 15 percent of 13-14-year-old children, which indicates a higher prevalence when compared with 6-7-year-old children (8.5 percent). During childhood (0-10 years) prevalence of Allergic Rhinitis (AR) is higher among males compared to females. Quite the reverse, during adolescence (11-17 years) females display higher prevalence of AR compared to males...

BACKGROUND: Pru p 3 is the major allergen of the peach and belongs to the LTP family. Pru p 3 sensitization has been associated with severe allergic symptoms after eating LTP-containing foods. However, a previous experience partially downsized the potential danger of Pru p 3 sensitization in a group of adult rhinitics. This study aimed to evaluate the real impact of Pru p 3 sensitization in children in a real-world setting. METHODS: 82 consecutive paediatric patients (55 males and 27 females, mean age 8...

BACKGROUND: Specific immunoglobulin E (sIgE) within the nasal airway is likely to be the most ideal marker of allergic status, but little is known of the normative values in asymptomatic patients and those with rhinitis. OBJECTIVE: The aim of this study was to assess the diagnostic characteristics of inferior turbinate tissue biopsy sIgE in asymptomatic and rhinitic patients. METHODS: A diagnostic cross-sectional study was undertaken, involving patients who underwent inferior turbinate surgery with or without other surgical interventions...

Bifidobacterium breve (B. breve) may have a beneficial effect on allergic rhinitis (AR). The aim of the present study was to investigate whether microbial induction of regulatory T cells (Tregs) and adjustment of Th1 and Th2 responses by B. breve are associated with protection against allergic inflammation, and to identify a dose-response association in a murine AR model. Ovalbumin (OVA)-sensitized BALB/c mice were orally treated with different doses of B. breve [1010 , 109 , 107 and 105 colony forming units (CFU)]...

PURPOSE: MP 29-02, which contains fluticasone propionate and azelastine hydrochloride, is used as a topical nasal application for the treatment of seasonal and perennial allergic rhinitis. Although a multitude of data is available on the clinical symptom reduction and treatment safety of MP 29-02, the effect of MP 29-02 on ciliary beat frequency (CBF) has not been evaluated thus far. METHODS: MP 29-02-containing solution was applied at concentrations of 2.5, 5, 10, and 20% to 14 healthy subjects, and nasal ciliated epithelial cells were then visualized using a phase-contrast microscope...

Children with atopic dermatitis (AD) usually develop symptoms when they reach the age of 6-7 years, but the risk of developing respiratory allergies, asthma and allergic rhinitis (AR) remains high. In most children with AD, the development of asthma and AR is associated with sensitization to food allergens and/or aeroallergens, while only a small percentage missed atopic diathesis. In about 35% of children with AD, food allergy is the provoking cause, and 60% of infants who had AD in the first 3 months of life were sensitized against aeroallergens by the age of 5...
