Filter by: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.
Single-center, case-control, longitudinal, observational, population based cohort study with stratified sample (by age group, gender, and residential area).
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.
The purpose of this study to determine the therapeutic response of non-allergic rhinitis patients that have been subtyped as non-allergic rhinitis with local IgE elevation or non-allergic rhinopathy to intranasal capsaicin based on visual analog scale and optical rhinometry, to determine the prevalence of non-allergic rhinitis with local IgE elevation in this study's cohort of patients with non-allergic rhinitis identified by rhinitis history and negative skin testing for allergic rhinitis, and to determine the change, if any, in intranasal IgE levels after capsaicin treatment.
WHO recommend to divide AR into 4 subgroups according to the symptom frequency (intermittent or persistent) and severity (mild or moderate-to-severe). For the persistent moderate-to-severe AR subgroup, the guideline suggests to treat with intranasal corticosteroid (INS) plus antihistamines (AH1) for 2-4 weeks. If the symptom is controlled then degrade the treatment (usually with INS) and maintenance for more than 4 weeks. However, up to 70% of patients suffering from AR do not follow treatment recommendation, they stopped medication when they feel better. This behavior always leads to uncontrolled AR, which has been identified as a high-risk factor of induction and exacerbation of asthma and chronic rhinosinusitis. A recent survey showed that AR patients prefer to an on-demand treatment rather than continuous treatment. In general, poor adherence is always a considerable issue for all long-term treatments. Previous studies have shown that as dosing frequency increases, the adherence rate decreases. Thus, less medication frequency is an important factor to optimize the management of chronic diseases including AR. Intranasal AH1 can relieve AR symptoms including sneezing, rhinorrhea and nasal itching in 3 to 5 minutes, while INS can inhibit the underlying mucous allergic inflammation and is recommended as the first-line medication for moderate-to-severe AR. INS combined AH1 have shown a synergic effect on control AR inflammation and provide rapid AR symptom relief. Investigators hypothesis that the on-demand administration of INS combined AH1 can achieve similar AR control level with less dosing frequency as compared to the daily INS maintenance in controlled moderate-to-severe AR patients.
The study is designed to assess whether allergic rhinitis and allergen immunotherapy affect the humoral response to SARS-CoV-2 Vaccination in adults. This is a prospective study enrolling a total of approximately 120 subjects, 18-55 years old.
Allergic rhinitis (AR) is an IgE mediated chronic inflammatory disease of the upper airways characterized by symptoms of sneezing, rhinorrhea, nasal itching, and nasal obstruction . However, not only this disease is difficult to cure, but also its relapse rate is high, therefore exerting a certain impact on their daily life, work and study. Nowadays, the main treatment for allergic rhinitis is the use of western medicine, such as steroids and antihistamines. However, many clinical studies have found that the curative effect of western medicine is often not ideal. Allergic rhinitis belongs to the category of "Rhinitis" in Chinese medicine. From the perspective of Chinese medicine, this disease is resulted from the deficiency of Qi and Yang Qi in the lungs, spleen and kidneys. Therefore, according to Chinese medicine theory, tonifying lung and spleen qi is the treatment principle for AR patients. Among different Chinese herbal formulae for AR, Yupingfeng san is commonly used for allergic diseases and in AR patients, due to its warm nature and able to improve the functions of the lungs and spleen. Yupingfeng san can improve symptoms and quality of life, as well as decrease the levels of interleukin and IgE in AR patients. This study will use Yupingfeng Powder with variation to evaluate its effectiveness and safety in treating AR. Hence, this study would be able to provide evidence on the efficacy and safety of Yupingfeng Powder with variation for AR.
To determine the Effectiveness of Montelukast Versus Intranasal Fluticasone Propionate in the Management of Allergic Rhinitis Among Children 02 to 05 Years of Age.
Allergic diseases, including allergic reactions of respiratory tract and skin, are often triggered by mast cell degranulation mediated by allergen-specific IgE and chronic inflammation of target organs, which are involved in a variety of immune cells and inflammatory factors. Recent studies have shown that intestinal immunity is closely related to immune responses to various diseases. Intestinal microecology influences the occurrence and regression of various diseases by regulating the growth, differentiation and maturation of various immune cells. Probiotics are widely used in children with allergies. This study aims to analyze the correlation between the intestinal microecology of children with rhinitis/asthma, eczema and urticaria and the clinical manifestations of the patients. By observing the influence of probiotics intervention on clinical symptoms and changes in intestinal microecology, the influence of intestinal microecology on children's allergic diseases was clarified. Study protocol: 1) children with definitive diagnosis of allergic rhinitis, asthma，atopic dermatitis and chronic urticaria were enrolled, each with 50 cases. 2) collect manure application of 16s rDNA probe hybridization technique to analyze the fecal flora, and compared with clinical symptoms rating scale and serum sIgE, IgG4 correlation analysis (3) application of probiotic intervention or conventional drug intervention, again in 3 months, 6 months after collecting dung is used to detect the intestinal flora in children with its correlation with clinical symptoms change were observed.
