Active clinical trials for "Rhinitis"

It has been demonstrated that allergic rhinitis (AR) reduces sleep quality by some components such as nasal obstruction. Pollution and allergen exposure worsening AR, sleep quality is deteriorated. Sleep is associated to physical and mental health, alterations in sleep could explain the link between AR and work productivity diminution, impairment in daily activities or emotional problems. However, interactions between air pollution, sleep and allergic diseases are insufficiently understood. The main objective of this study is to determine the impact of pollution and pollens on sleep parameters.

Allergic rhinitis might be caused by decreased resistance of nasal barrier to allergens and other environmental insults. About 20 % of the European population suffers from pollen allergies. Birch pollen allergic rhinitis is the most common allergic disease in the Scandinavia and it exists widely also in the Central Europe. Suffering and high costs of pollen allergies may be reduced by understanding the molecular biology of the nasal barriers during allergic response. Our aim is to observe the effect of season and birch pollen immunotherapy on the molecular biology of nasal epithelium and the microbiome.

The Purpose of A center, Randomized, Open label, single dose, Placebo-controlled, 2-Treatment, 2-Way, 2-Period Crossover Study to Compare the Safety and the Pharmacokinetic Characteristics of MKT-N2 (Montelukast) and Singulair® (montelukast sodium) tablet 10mg in Healthy Male Korean Subjects

This is an open-label, randomized, multicenter, 2-way crossover study in subjects 12 years or older with perennial allergic rhinitis (PAR) to evaluate the psychometric properties of a novel-patient administered assessment of treatment satisfaction with and preference of an Internasal Corticosteroid (INCS)

Specific immunotherapy for IgE mediated sensitization to grass pollen 4 concentrations of a modified pollen extract of Phleum pratense are applied to find out the optimum dose.

The trial is randomized prospective study to examine the effects of subcutaneous immunotherapy on the adaptive immune system. The trial includes 30 participants randomized to treatment or control group. The effect measures are changes in the basophil activity and biology as well as changes in plasma cells during and after treatment. Clinical outcome is assessed by QoL questionnaires and clinical testing. Hypotheses: changes in plasma cells correlate to changes in immunoglobulins and effector cell responses the reduction of inflammation due to SCIT has influence on the effector cell responses changes in paraclinical measurements can be related to clinical findings

Treatment of pollen allergies can be roughly divided into symptomatic treatment (e.g. antihistamines, steroids) and potentially curative immunotherapy. Immunotherapy can be delivered using subcutaneous or oral (mucosal) routes, with similar clinical outcome. The study seeks to compare immunological changes during subcutaneous (SCIT) and sublingual tablet (AIT) immunotherapy of grass pollen allergy (hayfever).

There is inconclusive evidence whether acupuncture treatment is effective in the treatment of seasonal allergic rhinitis (SAR). Furthermore, the underlying mechanisms of acupuncture in SAR are only poorly understood. It was hypothesised that the therapeutic mechanism of acupuncture is related to changes in autonomic function. AUTO-ACUSAR is a sub-study of the DFG-funded three-arm randomized controlled trial ACUSAR trial investigating the efficacy of acupuncture vs. sham acupuncture vs. rescue medication in SAR. The aim of AUTO-ACUSAR was to investigate short and long-term effects of acupuncture vs. sham acupuncture on autonomic function in a sub-group of ACUSAR patients. Baseline values were compared to data from matched healthy controls.

The hypothesis is that treating hay fever patients who had daytime sleepiness and slowed thinking because of the hay fever will improve when treated with an effective anti-hay fever medication, an intranasal steroid, that is will have less daytime sleepiness and demonstrate better thinking.

Allergic rhinitis (AR) is a condition that exists when an individual with a specific allergy reacts to that allergen resulting in a runny and/or stuffy nose, postnasal drip, and possible symptoms of sneezing, scratchy throat, itchy nose, ears or throat. When the allergic person is exposed to such an allergen, the body reacts with overproduction of certain chemicals which cause inflammation and subsequent symptoms of AR. These responses are related to the body's hyperreactive response to exposure to an otherwise harmless substance such as dust, ragweed, pollen, cat dander etc. There are data to suggest that air pollution resulting from diesel exhaust can increase the body's response to airway inflammation caused by virus. The purpose of this research study is to determine if individuals with AR have increased inflammatory responses to flu virus following exposure to diesel exhaust (DE) vs exposure to clean air compared to how individuals who do not have allergies respond to the same exposure conditions. The hypothesis for this study is that diesel exhaust exacerbates LAIV-induced allergic nasal inflammation, using controlled exposures in AR volunteers compared to non-allergic individuals
