View clinical trials related to Rhinitis.
Filter by:Allergic rhinitis is a common illness suffered among US Veterans. There are medications that help relieve allergy symptoms, including nasal steroid sprays and antihistamines. Some patients have increase symptoms with exposure to their trigger, such as a grasses when combined with pollution due to oxidative stress from pollution. In this study, patients with allergic rhinitis to grass will be given broccoli sprout extract that contains an antioxidant sulforaphane do see if there is beneficial effect in these patients.
Nasal symptoms are the main elements that lead to a therapeutic decision and allow for evaluating treatment effects or natural evolution. Despite availability of several questionnaires with good measurement qualities, no systematic assessment takes into account the specific physical and psychosocial consequences of each of the six main nasal symptoms, independently of the disease. The study proposed to measure these symptoms with the use of a selfreport questionnaire and to test the validity of the questionnaire in a large representative sample of patients attending outpatient rhinologic clinics.
Study to evaluate the efficacy, safety and tolerability of GSP 301 NS compared with placebo NS and individual monotherapy formulations for the treatment of Seasonal Allergic Rhinitis (subjects 12 years of age and older)
The investigators will evaluate sensitization to animal allergens and allergic symptom during contacting animal allergens in Korean veterinary researchers who attend their annual conference. The investigators will compare sensitization to animal allergen and other clinical and occupational factors between subjects who suffer from allergic symptom during contacting animal and those who do not.
The purpose is to obtain real-world information on how consumers are complying with the product labelling This study will coincide with the launch of Pirinase Hayfever Relief for Adults 0.05% Nasal Spray in the United Kingdom (UK).
This is an observational prospective study to assess the tolerability and safety of treatment of SCIT Allergovac Poliplus polymerized in depot presentation. The study drug will be administered either by a 1 day Schedule or by a rapid Schedule (3 increasing weekly doses at initiation period till maintenance dose is reached) The study population is both: adult and child, polysensitized to at least 2 allergen sources with rhinitis or allergic rhinoconjunctivitis. Patients may also present a concomitant mild or moderate asthma. The assignment of a patient to a particular therapeutic strategy will not be decided in advanced by a trial protocol but will be determined by routine clinical practice. The decision of the investigator to prescribe a particular treatment will be clearly dissociated from the decision to include the patient in the study. The patients will not suffer any intervention, whether diagnostic or monitoring, other than the usual in clinical practice.
This is a pilot cross-sectional study of measured transcutaneous CO-oximetry in children with inflammatory and non-inflammatory conditions.
This is a single-arm pilot study designed to evaluate the feasibility of cryoablation in the nasal passageway, using the ClariFix device, to reduce the symptoms of chronic rhinitis.
The purpose of the study is to investigate the incidence of non-allergic rhinitis on a not selected group of young students (n=100-300). Students will be selected by public posting. In all students an allergy skin test will be performed. Then the local IgE of 24 subjects with non-allergic rhinitis will be compared to the local IgE of 24 subjects with allergic rhinitis and positive prick test to house dust mite. In addition 20 controlls will be investigated. Based on these investigations, the importance of local IgE and the IgE spectrum in conjunction with rhinitis should be further clarified.
Chronic rhinosinusitis (CRS) with nasal polyps is a particularly challenging form of chronic rhinosinusitis in several ways. Patients have significantly more severe symptom burden and worse quality of life than patients with chronic rhinosinusitis without nasal polyps. Many patients return to the health care providers with persistent symptoms after repeated medical and surgical treatment. Patients have usually tried several different types of treatments, ranging from less invasive procedures to extensive surgical treatment. The surgical treatment is often repeated several times. The most common surgical treatment is functional endoscopic sinus surgery, another established procedure is Vidian neurectomy. The main object of this pilot study is to investigate the safety of onabotulinumtoxin A towards the sphenopalatine ganglion (SPG) in CRS patients with nasal polyps. Efficacy data will also be collected to provide indication on whether future placebo-controlled studies should be performed. Onabotulinumtoxin A inhibits the secretion of acetylcholine, blocking the parasympathetic reflex cascade in the SPG. As a result, the investigators expect less mucosal swelling, secretion and nasal polyps. The duration of such a blockade is believed to last for 3-9 months and will not lead to damage of the nerve. This study opens up for improved treatment with less complications.
