Filter by:Allergen immunotherapy (AIT) is used for the control of allergic diseases that are not completely responsive to avoidance strategies and/or pharmacotherapy. It is also considered the main treatment with the potential to modify allergic disease evolution. It's efficacy and safety in allergic rhinitis and asthma is supported by large systematic reviews and is recommended as a cornerstone treatment option in allergic disease. Molecular based allergy diagnosis has greatly evolved and the knowledge of molecular allergen sensitization pattern has been used to better define the allergen extract composition of AIT. However, uncertainty remains if this strategy is related to an increase of efficacy. Regulation of allergen extracts for allergen immunotherapy are currently underway in Europe, but there is still lack of standardization of relevant allergens and important differences are seen between allergenic contents. Therefore, we aim to evaluate, in a real-life setting, the impact of using molecular-based diagnosis versus standard diagnostic tools in the efficacy of aeroallergen immunotherapy, using a pragmatic randomized controlled trial design and also to address the impact of the discrepancy between individual aeroallergen sensitization profiles and the major allergen molecular content of aeroallergen immunotherapy.
This study aims to establish dose-responses to nasal allergen challenge using silver birch pollen and house dust mite allergen extracts in participants with allergic rhinitis, sensitised to either or both of these allergens. The allergen extracts used will be Itulazax tablets (silver birch pollen allergen sublingual tablets, ALK-Abello, Denmark) and Acarizax tablets (house dust mite allergen sublingual tablets, ALK-Abello, Denmark). The results will allow identification of the dose of each allergen typically producing a moderate severity response, which could then be used in future, interventional and investigational studies. A control group - healthy individuals with no allergic rhinitis - will be recruited to demonstrate the absence of an irritant/non-allergic effect of the nasal allergen challenge procedure.
Background: Shiners are caused when blood and other fluids accumulate in the infraorbital groove. It develops resulting from lots of problems. In patient with rhinitis, either allergic rhinitis or non-allergic rhinitis, shiners are believed to be caused by venous stasis resulting from nasal congestion. This study is aiming that comparison of the effectiveness of treatment of rhinitis (either allergic rhinitis or non-allergic rhinitis) to lighten not only the rhinitis but also the shiners. Randomized control studies. Design: The investigators will recruit children (6-12 y/0), adolescent (13-18 y/o), or adults (19-65 y/o) with either allergic rhinitis or non-allergic rhinitis, and patients will be randomly assigned to groups (oral antihistamine, combined nasal corticosteroids with oral antihistamine, combined nasal corticosteroids with oral antihistamine plus nasal decongestant, combined nasal corticosteroids with oral antihistamine plus nasal irrigation, combined oral antihistamine with nasal irrigation, or nasal antihistamine only). Digital image will be recorded and analyzed to compare the change of shiners between before and after treatment for rhinitis. The clinical data were collected including patient's data, history, laboratory data, Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ), Adolescent Rhinoconjunctivitis Quality of Life Questionnaire (AdolRQLQ), or mini Rhinoconjunctivitis Quality of Life Questionnaire (mini-RQLQ), and medications. The primary outcome is to answer whether the levels of shiners can be alleviated by using therapies in patient with rhinitis. And the secondary outcome is to figure out which therapies work most effectively. Keywords: allergic rhinitis, vasomotor rhinitis, shiners, nasal corticosteroids
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.
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 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.
