Filter by: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.
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.
Allergic rhinitis (AR) is a health problem characterised by an inflammatory reaction in the nasal mucosa mediated by immunoglobulin (Ig) E and resulting from exposure to environmental allergens, such as pollen and dust mites. AR symptoms can significantly affect the quality of life of patients suffering from AR, causing substantial direct health care costs and indirect costs due to absenteeism from work. The effects of pharmacological treatments are not always fully effective and have adverse effects, resulting in a significant proportion of AR patients continuing to experience symptoms or being dissatisfied. Considering the relationship between AR and intestinal microbiota (IM), the use of probiotics, live microorganisms that, when consumed in adequate amounts, confer beneficial effects on the host, emerges as a potential strategy to prevent or treat certain allergies. There are different mechanisms of action by which probiotics may exert their effects on the treatment or prevention of allergies through modulation of the immune system and stimulation of tolerance. Probiotics promote a change in IM. In addition, probiotics stimulate gut-associated lymphoid tissue, modulating inflammation and immune reactions present in AR, promoting a more favourable profile by increasing the production of the modulatory cytokines IL-10 and TGFβ by Treg cells. Probiotics can restore the Th1:Th2 balance by inducing Th1 responses through the production of IL-12 and interferon (IFN)-γ, or by suppressing Th2 responses through the depletion of IL-4. In addition, probiotics may exert immunomodulatory effects through stimulating mucosal IgA production. The hypothesis of the present study is that supplementation with the probiotic Bifidobacterium longum ES1 and/or with the heat treated version of ES1 will decrease the symptomatology associated with AR and improve the quality of life of individuals by modulating IM and potentiating Treg cells and the Th1 response. The main objective of the present study is to determine the effects of supplementation with the probiotic Bifidobacterium longum ES1 and the heat treated version of ES1 (HT-ES1) on the symptoms associated with AR. The secondary objectives of the study are to determine the effects of the treatments over: 1) Quality of life; 2) Blood immunological markers (IFN-γ, IL-12, IL-10, TGF-β, IgE, IL-4, IL-13, IL-19 and IL-8); 3) Faecal immunological marker IgA; 4)Faecal microbiota composition.
The investigators is now carrying out a clinical study of Umbilical cord Mesenchymal Stem Cells (UCMSCs) in the treatment of Allergic rhinitis (AR). UCMSCs is known to its multilineage differentiation potential, strong proliferation ability, low immunogenicity, convenient material acquisition, and fewer restrictions on ethical and moral issues. The investigators hope to find a novel, minimally invasive, effective and simple treatment for the large number of patients with persistent moderate to severe AR.
The aim of the study will be to investigate the prevalence of of sensitization to peach and/or cypress in potato sensitized patients, based on the collection of medical data from patient records consulting in the Allergy Unit of the Arnaud de Villeneuve Hospital. Some Gibberellin-regulated protein (GRP) in fruits and pollens have been identified as allergen, and peach GRP (peamaclein) has recently emerged as a relevant food allergen in cypress pollen-hypersensitive patients. Multiple fruit allergies might be related to cross-reactivity between GRPs. Peamaclein shares 82% identity with snakin-1 from potato. Thus, because of this hight homology the investigators want to determine the prevalence of cosensitization between these 3 allergens potato, peach and cypress.
