Active clinical trials for "Rhinitis, Allergic"

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.

Rhinitis is defined clinically as having two or more symptoms of anterior or posterior rhinorrhea, sneezing, nasal blockage and/or itching of the nose during two or more consecutive days for more than 1 h on most days. Allergic rhinitis is diagnosed when these symptoms are caused by allergen exposure leading to an IgE mediated reaction. The inflammatory mediators produced because of this IgE mediated reaction causes the classical symptoms of allergic rhinitis. Nerve irritation causes sneezing and itching, the loss of mucosal integrity causes rhinorrhea, and the vascular engorgement leads to nasal blockage. Based on the nasal symptoms the prevalence of allergic rhinitis in the Indian population is 20-30%. Allergic rhinitis significantly affects the quality of life, it contributes to missed or unproductive time at school or work, disturbed sleep pattern and daytime somnolence. The most popular and widely accepted treatment strategy for allergic rhinitis is pharmacotherapy, this includes antihistamines, leukotriene receptor antagonist and intranasal corticosteroids. These medical modalities are symptomatically effective in mild cases, with temporary relief and addressable adverse effects. Prolonged treatment with allergy immunotherapy causes a sustainable financial burden while remaining inaccessible at smaller towns. Rhinorrhea is a frequent symptom reported amongst patients with allergic and vasomotor rhinitis. Most of these patients usually respond well to medical treatment. Indications for surgical treatment are warranted only when medical treatment fails, or a patient wants a permanent solution. In 1961, Golding-Wood first described vidian neurectomy for the treatment of allergic and vasomotor rhinitis. There was a high incidence of post-operative complications, such as disturbed lacrimal secretion and numbness of the cheek and gums. In 2007, Kikawada reported an endoscopic technique involving resection of the posterior nasal nerve near the sphenopalatine artery. With this technique, any intra-operative bleeding can be controlled under direct vision. In 2008, Ikeda et al. described submucosal reduction of the inferior turbinate and resection of the posterior nasal nerve. This resulted in significant improvements in nasal symptoms for patients with resistant chronic rhinitis (rhinorrhea). The posterior nasal nerve is a peripheral branch of the sphenopalatine ganglion. It enters the nasal cavity through a separate foramen, 4-5 mm below the sphenopalatine foramen, after bifurcation of the nerve into the lacrimal nerve. The posterior superior nasal nerves innervate the superior and middle turbinates, and the superior and middle meatus. Other parasympathetic nerve fibres of the nose branch off and joins the greater palatine nerve and enters the nasal cavity through the canaliculi in the perpendicular plate of the palatine bone as the posterior inferior nasal nerves. These nerves innervate the inferior turbinate and the inferior meatus.

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 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.

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

Allergic rhinitis (AR) is an immunoglobulin E-mediated inflammatory disease1 caused by hypersensitivity of the immune system to an allergen, affecting 100 million people in Europe 2and 400 million of the global population.The etiology of AR is multifactorial, resulting primarily from genetic predisposition, immunological response, and environmental pollutants.AR traditionally has been classified as seasonal (SAR) or perennial (PAR) depending on the causes and duration of symptoms. Some patients with AR prefer complementary and alternative medicine for their symptoms, with nearly 20% receiving acupuncture. According to the updated practice parameter of rhinitis in 2020, the use of acupuncture for the treatment of AR was not recommended due to a lack of well-controlled studies. The sphenopalatine ganglion (SPG), located under a thin (1-2 mm) layer of mucosa in the pterygopalatine fossa, consists of sensory fibers that innervate the nasopharynx, nasal cavity, and palate.Several studies have reported the benefit of SPG stimulation in chronic cluster headache and acute ischaemic stroke. Compared with traditional acupoints selected on basis of traditional meridian theory, acupuncture at SPG(inserting a needle through SPG acupoint (near ST7, Xiaguan) to reach and directly stimulate the SPG) may help patients ameliorate nasal symptoms immediately and improve quality of life by increasing sympathetic nerve excitability, but the evidence is inconclusive. We have designed this three-armed, randomized trial to investigate the efficacy and safety of acupuncture at SPG for the treatment of SAR. We hypothesize that acupuncture at SPG plus rescue medication is superior to sham acupuncture plus RM and RM alone in the treatment of SAR.

This is a Phase I/Ib, randomised, double-blind, placebo-controlled study of INI-2004, administered as single or multiple doses. This study will be conducted in two parts: Phase I single ascending dose (SAD) and Phase Ib multiple ascending dose (MAD).

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 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.
