Active clinical trials for "Rhinitis"

IgE-associated allergy is a hypersensitivity disease affecting more than 25% of the population in industrialised countries. The recognition of allergen by immunoglobulin E (IgE) plays a central role in the cause of allergic diseases. Both seasonal and nasal provocation studies have demonstrated the rise in specific IgE after allergen exposure. Additionally changes in other clinical and immunological parameters (e.g. nasal blockage, mast cell and basophil sensitivity, various cytokines or T cell profiles) in response to allergen exposure have been described. However the time sensitive interplay of these various factors such as the relationship between rise in IgE levels and change in basophils sensitivity or cytokine profiles is not yet fully understood. Clarifying how these various factors interact and contribute to immunological responses to allergen, is crucial for the development of new therapeutic approaches. The investigators aim to address these questions through a study following 36 Birch allergic patients after provocation with allergen or placebo over a peroid of 6 weeks to 1 year.

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)

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

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).

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.

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 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

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.

This was a crossover study designed to see if patients with seasonal allergy symptoms preferred Clarinex® or Allegra®. Patients were randomized to take 7 days of Clarinex or Allegra treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Allegra, the patient prefers more.
