Filter by:The ragweed Ambrosia artemisiifolia is spreading in northern Europe due to climate change. The pollen are considered highly allergenic and might trigger allergy symptoms at much lower concentrations than e.g. grass or birch pollen. This study aims to determine threshold concentrations for ragweed and birch pollen in patients with seasonal allergic rhinitis. Participants will be exposed in an allergen challenge chamber that was technically modified to maintain very low and stable pollen concentrations for several hours. The study design is adaptive, where the pollen concentrations are escalated or de-escalated based on interim analysis of resulting allergic symptoms.
The purpose of the current study is to evaluate the efficacy of administering a multistrain probiotic in adult human subjects suffering from allergic rhinitis and evaluate both symptomatology through validated questionnaires and gut microbiota modification during and after treatment.
This is a mechanistic, controlled, open-label, single-site study to evaluate the effects of RG-RV16 inoculation on airway mucosal gene expression and airway remodeling in 25 healthy controls (HC), in 25 allergic rhinitis subjects (AR) with cat dander allergy, and in 25 allergic asthmatic subjects (AA) with cat dander allergy. Three groups (HC, AR, and AA) will undergo screening to establish clinical history, will undergo pulmonary function testing (spirometry), and will have blood drawn for clinical characterization (IgE, , ImmunoCAP, CBC and differential), and for assessing the presence of existing neutralizing antibody against RV16. Only those who meet criteria will be permitted to continue into the interventional and run-out phases of the study.
To investigate the Influence of Climatic and Environmental Factors on Respiratory or Allergic Diseases in Sanya.
Allergic rhinitis (AR) is a noninfectious inflammatory disease of the nasal mucosa mediated by immunoglobulin E (IgE) after exposure to allergens. Artemisia annua is one of the most important allergen that is responsible for seasonal AR in China during July and October. Allergen specific immunotherapy (AIT) is the only etiological treatment available for AR. The trial is a randomized, Open label, multicentred trial. A total of 150 subjects with allergic rhinitis caused by Artemisia pollen were recruited and randomized to the immunotherapy group and conversation drugs group.
The trial will be conducted as a prospective, randomized, multinational, multicenter, double-blind, placebo and active controlled trial in 4 parallel-groups of patients suffering from seasonal allergic rhinitis.
Objective Seasonal allergic rhinitis (SAR) is a common disease in childhood and characterized by type 2 inflammation, bothersome symptoms, and impaired quality of life (QoL). Intranasal corticosteroids are effective medications in managing SAR patients. In addition, mometasone furoate nasal spray (MFNS) is a well-known therapeutic option. However, the literature provided no data about its effects in European children with SAR. Thus this study addressed this unmet need.
Allergic rhinitis in children is common. According to the international study of asthma and allergies in childhood (ISAAC) phase III, the global prevalence of allergic rhinitis among children is increasing to 40.1% and the prevalence of allergic rhinitis in Bangkok area in 2018, among children aged 6-7 and 13-14 years was 16.32%. This disease is a global health problem affecting quality of life of patients in daily life, work, study and sleep. Intranasal corticosteroid is the most effective treatment for allergic rhinitis. From real world evidence; most of allergic rhinitis patient use the drug when symptoms worsen. In children, the use of intranasal corticosteroid may cause minor local side effects such as dryness, burning sensation or epistaxis. In some intranasal corticosteroid, long-term use may result in decreased growth compared to placebo which make parents concern. The investigators interested in studying the efficacy of intranasal corticosteroid comparing between daily use and as needed use in children with allergic rhinitis. To study the appropriate form of treatment to increase cooperation. Patient will have a better quality of life and reduce the risk of side effects from prolonged use of intranasal corticosteroid. From the literature review, it was found that most studies were conducted among adult patients with seasonal allergic rhinitis In Thailand in 2020, Thongngam et al. studied the efficacy of intranasal corticosteroid was compared between daily use and as needed use in adult patients with perennial allergic rhinitis. The results of the study concluded that the daily use group can reduced more TNSS (total nasal symptoms score) but was not statistically significant and had a greater increase in peak nasal inspiratory flow (PNIF) compared to as needed group. Interestingly, the quality of life assessment (RCQ-36 score) in both2 groups improved equally, In as needed group, the cumulative dose was 51% lower than the daily dose group. The investigators want to compare the efficacy of intranasal corticosteroid between daily versus as needed use in children with perennial allergic rhinitis which had not been studied before.
The primary goal is to investigate the efficacy of intralymphatic immunotherapy (ILIT) for the treatment of allergic rhinitis and allergic asthma due to sensitisation to grass pollen allergens. 60 patients with allergic rhinitis will be included and randomized to receive either Polvac (n=30) or placebo (n=30). All patients will receive three injections with 4-8 weeks interval. The injections into a inguinal lymph node is guided by sonography. Patients will record symptoms and medication use in the summer of 2022 and 2023.
The objective of this study is to compare the effectiveness of batten grafts plus septoplasty and turbinate reduction (intervention arm) compared to septoplasty and turbinate reduction alone (control arm), both in terms of subjective and objective assessments.
