Filter by:The goal of this clinical trial is to learn about the clinical efficacy and safety of ganciclovir (GCV) capsules in the treatment of refractory moderate-to-severe allergic rhinitis. The main questions it aims to answer are: 1. Whether ganciclovir improve nasal symptoms and life quality in patients with refractory moderate-to-severe allergic rhinitis. 2. Whether ganciclovir is safe for the treatment of allergic rhinitis. Participants with refractory moderate-to-severe allergic rhinitis will be included in the trial based on the inclusion and exclusion criteria, and randomized into experimental and control groups. The two groups will be treated with blinded ganciclovir capsules or placebo for two weeks, with the background therapy of mometasone furoate aqueous nasal spray. A placebo is a look-alike capsule that contains no active drug. Nasal symptom scores, nasal secretions, blood samples and adverse events will be collected during the visits. Researchers will compare the experimental and control groups to see whether ganciclovir improve symptoms and is safe for the treatment of refractory moderate-to-severe allergic rhinitis.
The main purpose of this study is to evaluate the efficacy and safety of lebrikizumab in adult participants with perennial allergic rhinitis. The study will last about 18 months
Allergic rhinitis (AR) is a global health problem affecting approximately 10% to 40% of the population worldwide, with an increasing trend. It significantly impacts health and quality of life. Current treatments for AR include allergen avoidance, symptom-relieving medications, anti-inflammatory therapy, and allergen-specific immunotherapy. However, many patients still experience uncontrolled symptoms despite these approaches, either as monotherapy or in combination, along with medication side effects such as drowsiness, dry eyes, nasal mucosal damage, and immunosuppression. Auricular acupressure therapy (AAT) utilizes ear acupoints by applying pressure with ear seeds. The neurobiological mechanisms of AAT on the human body have gained increasing attention in clinical and experimental studies, involving anti-inflammatory, antioxidant, and immunomodulatory effects. Its efficacy has been recognized, becoming a potential alternative therapy for various conditions such as sleep disorders, obesity, and chronic pain. Previous clinical studies have reported the efficacy and safety of AAT in treating AR. However, the primary outcomes of these studies remain inconsistent and lack specific criteria for evaluating AR treatment efficacy. This study aims to investigate the efficacy and safety of AAT in treating AR based on the ARIA guideline 2019 treatment efficacy criteria. It will provide a basis for applying AAT as a complementary approach in the multimodal treatment of AR.
Allergic rhinitis (AR) is a common condition, with nearly 300 million affected individuals in China, significantly impacting the quality of life. Despite standardized drug treatments, approximately 20% of AR patients experience inadequate control and require surgical intervention. AR manifests as nasal itching, sneezing, clear nasal discharge, nasal congestion, primarily associated with inflammation-induced hypertrophy of nasal turbinates and a heightened neurogenic state of the nasal mucosa. Surgical treatment focuses on "reducing hypertrophy" of nasal turbinates and "desensitizing" neurogenic hyperreactivity.High-intensity focused ultrasound (HIFU), as a minimally invasive therapeutic modality in AR, is still in its early stages of application and requires further multicenter clinical studies and widespread adoption. This project collaborates with six established institutions proficient in ultrasound treatment for AR. It aims to conduct a prospective multicenter observational study and subsequent dissemination, emphasizing the application of "reduction of hypertrophy" and "desensitization" in AR.Through standardized case selection, subjective and objective measures such as subjective symptom scores, quality of life assessments, nasal reflex, and nasal resistance tests before and after treatment will be employed to evaluate the effectiveness and safety of HIFU in "reducing hypertrophy" and "desensitizing" aspects of AR. Simultaneously, building on our established Otolaryngology Head and Neck Surgery Alliance and Southwest Allergy Alliance, the research results will be promoted through lectures, hands-on guidance, training sessions, academic conferences, and other means to facilitate the application of HIFU in AR and benefit a larger population of AR patients.
Allergic rhinitis (AR) currently affects ~25% of Canadians, and due to factors of climate change, this number is expected to increase over the coming decade. AR symptoms can significantly impact individuals' quality of life by compromising sleep, productivity, and social interactions. To alleviate AR symptoms, North Americans tend to rely on H1 antihistamine medications available over-the-counter (OTC) at most pharmacies. However, public health authorities currently suggest restraining all antihistamines during heat waves due to beliefs that M3 muscarinic receptor and H1 receptor antagonism, independent pharmacological mechanisms of H1 antihistamines, might suppress thermoregulatory responses to heat stress and increase individuals' susceptibility to heat-related illness/injury. To date, studies using supramaximal doses of antihistamines have demonstrated reductions in sweating, however these doses and administration routes are not the typical use case. Additional studies utilizing fexofenadine, a second-generation H1 antihistamine, have linked H1 receptor antagonism to reductions in skin blood flow, potentially impacting thermoregulation by reducing peripheral blood redistribution. Empirical evidence supporting OTC H1 antihistamines impacting thermoregulatory control at recommended doses is scarce. Thus, this study aims to systematically assess whether three common OTC H1 antihistamines, taken as prescribed, alter thermoregulatory responses during thermal stress.

The goal of this clinical trial is to learn about how well tezepelumab (pronounced TEZ e PEL ue mab), a Health Canada-approved drug for severe asthma, works in participants with coexisting allergic asthma and allergic rhinitis (hayfever). The main questions it aims to answer are: - How well does the study drug work to reduce nasal symptoms following exposure to an allergen after 6 doses, and after 12 doses? - Does the study drug reduce chemicals found in the nose known to be involved in the allergic rhinitis response? Both allergic and non-allergic participants will be enrolled in the study. Non-allergic participants will: - Not be receiving the study drug. - Be exposed to allergen via the Nasal Allergen Challenge, which involves the administration of allergen extract directly to the nose. - Complete nasal symptom and quality of life questionnaires - Have nasal fluid and blood samples collected at various time points up to 24 hours following allergen exposure. - Visit the clinic 3 separate times: - At a screening visit to determine their eligibility to participate in the study - At the baseline Nasal Allergen Challenge visit - At the 24-hour post-Nasal Allergen Challenge follow-up visit Allergic participants will: - Receive one dose of tezepelumab every 1 month for 12 months. Tezepelumab will be administered as an injection into the fatty layer just beneath the skin on the stomach, arm, or thigh. - Be exposed to allergen via the Nasal Allergen Challenge, which involves the administration of allergen extract directly to the nose. - Complete nasal symptom and quality of life questionnaires - Have nasal fluid and blood samples collected at various time points up to 24 hours following allergen exposure. - Visit the clinic 17 separate times: - At a screening visit to determine their eligibility to participate in the study - At the baseline, 6-month, and 12-month Nasal Allergen Challenge visits - At each 24-hour post-Nasal Allergen Challenge follow-up visit - For each dose of the study drug The investigator will compare changes in nasal symptoms and allergic chemicals measured from nasal fluid and blood samples between non-allergic participants and allergic participants at baseline and at 6- and 12-months following the use of the study drug.

Allergic rhinitis is one of the most common inflammatory conditions of the upper airway mucosa, especially in the pediatric population with a prevalence of approximately 25%. It is among the most common chronic inflammatory diseases globally and is caused by IgE-mediated reactions to inhaled allergens, often co-occurring with asthma and causing severe burdens and disabilities worldwide. Allergic rhinitis can in fact seriously compromise the quality of life, significantly influencing school performance, social life and the quality of sleep. It is known that the most common symptoms characterizing allergic rhinitis (itching of the nose, sneezing, rhinorrhea and nasal/sinus obstruction) are partly overlapping with those due to a condition of deviation of the nasal septum and a recent study has shown how 87 % of patients with persistent allergic rhinitis are affected by at least 1 of the 7 types of nasal septum deformity. Deviation of the nasal septum is a very frequent anatomical disorder and is present in up to 48% of children and adolescents in the general population. The deviation narrows the affected nostril canal, reducing the flow of air that passes through the nostrils, predisposing to chronic mucosal inflammation with inflammatory infiltrate and in turn increasing the risk of developing chronic rhinitis and sinusitis. There are no data in the literature that correlate nasal septum deviation with an increased risk of developing allergic rhinitis. Given these premises, the ARHINASD (Allergic Rhinitis in pediatric topics with Nasal Septum Deviation) study was designed with the primary objective of evaluating the presence of allergic rhinitis in a sample of patients with and without deviation of the nasal septum.
