Active clinical trials for "Rhinitis, Allergic"

Prospective, randomised, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of polymerized and mannan conjugated allergen extract of Dermatophagoides for the treatment of allergic rhinitis/rhinoconjunctivitis with or without asthma. The main objective of the clinical trial is to evaluate the clinical efficacy of the investigational medicinal product, administered sublingually, compared to placebo for the treatment of moderate-severe rhinitis/rhinoconjunctivitis with or without mild to moderate asthma and controlled using the Rhinitis/Rhinoconjunctivitis Combined Symptom and Medication Score (R-CSMS).

This study aims to investigate immune mechanisms and phenotypes and endotypes of allergic airway diseases - allergic rhinitis and allergic asthma. Pathogenesis of these diseases are not fully investigated yet. Patients with the same disease have different dominant symptoms, course of the disease and response to treatment. Moreover, there is a hypothesis about united airway disease suggesting that allergic rhinitis and allergic asthma is different manifestation of the same disease. This led to assumption of phenotypes and endotypes. This classification which still is not unified can let to prescribe personalized treatment for every patient.

To investigate the Influence of Climatic and Environmental Factors on Respiratory or Allergic Diseases in Sanya.

The goal of this observational study is to learn about the agreement between sensors analyzing algorithm and body plethysmography in measuring oral and nasal breathing in healthy adults, and in patients with chronic rhinosinusitis, asthma and chronic obstructive pulmonary disease. The main question it aims to answer is: • Is the algorithm-based method accurate enough in analyzing respiratory obstruction as compared to body plethysmography (reference method)? Participants will perform a short breathing protocol (oral and nasal breathing with different masks) during which time their breathing is monitored with both methods.

Eosinophilic esophagitis (EoE) is a chronic inflammatory esophagus disease that is presented in patients with a history of recurrent dysphagia. EoE is closely related to other pathologies with an immuno-allergic etiopathogenesis such as atopic dermatitis (AD), IgE-mediated food allergy, allergic rhinitis and bronchial asthma. While the importance of the correlation between diet and food allergy has been largely demonstrated, less is known about the exact role of sensitization to aerollergens in the progression and recrudescence of symptoms. In support of this correlation there is evidence of a seasonal trend in the new diagnoses of EoE, of the possibility of the de-novo onset of the pathology following massive exposure to a specific aeroallergen and the demonstration that the degree of esophageal eosinophilia varies according to the climatic zone and the season of the year. The detailed knowledge of this correlation could clarify some aspects of the etiopathogenesis and natural history of EoE, improve and personalize the clinical-diagnostic management of affected patients and provide new therapeutic targets. Our aim is evaluating the possible existence of a correlation between the recrudescence of dysphagia symptoms and a specific month of the year and/or specific season.

Observational, cross-sectional, prospective, multicentric study in France with private paediatricians to describe the management of allergic rhinitis in children.

Cat allergy is the most common animal allergy, affecting approximately 1 in 5 adults worldwide. The prevalence of allergy to furry animals is increasing, and cat allergy is a major risk factor for the development of asthma and rhinitis. Fel-d1 is the major feline allergen, to which 95% of cat allergic people react. All cats produce Fel-d1 regardless of breed, age, coat type, sex or weight. Fel-d1 is contained primarily in the saliva and sebum of cats. This allergy manifests itself as allergic rhinitis (AR) (sneezing, cold, coughing, conjunctivitis with watering and itching), severe asthma, and irritation and swelling of the skin when scratched. A new approach to managing cat allergies is to neutralize the allergens at the source by feeding domestic cats a diet containing anti-Fel-d1 IgY antibodies. The purpose of this pilot study is to determine whether feeding domestic cats a food containing an egg product with anti-Fel d1 IgY (PRO PLAN® LIVECLEAT®) induces a reduction of allergic symptoms in their owners.

The investigators are investigating the early and late responses to allergen challenge. The research participants who the investigators will study (from three cohorts) will be part of independently-approved studies involving allergen challenge. Due to the uniqueness of the cohorts for novel genetic study, it is logical that the investigators should initially undertake hypothesis-generating experiments. The investigators will obtain blood samples from the participants, both pre-challenge and post-challenge. The investigators will determine gene expression and protein differences between these samples, and investigate if there are inherited genetic differences between individuals that may predict their specific responses to allergens.

Allergy is a public health problem as more than 20% of western society is affected by it. Symptomatic treatment of allergy suffices with less severe allergy. Patients with more severe allergy should be treated with allergen immunotherapy (AIT). Present options of AIT are efficient but of long duration, associated with side effects and require much time from the patient. With Intralymphatic immunotherapy (ILIT), allergen is injected into the lymph node under ultrasound guidance. ILIT is complete after 3 treatment visits, may be more effective than and may have markedly fewer side effects than presently available methods of AIT. The investigators plan a randomized, parallel group, open-label, prospective case-control study to assess immunological changes in lymph node and peripheral blood after intralymphatic (ILIT) or subcutaneous (SCIT) immunotherapy with POLVAC. The intervention consists of one ultrasound-guided injection of allergen into inguinal lymph node or subcutaneous injection 1 cm next to the lymph node. Intervention quality (accuracy of injection) will be assessed by the administering physician during treatment and via video recording on the ultrasound device. Side effects associated with treatment will be recorded by the patients for 3 days after the injection. The effect of intralymphatic or subcutaneous injection on lymph node tissue and immunoglobulins E and G4 in serum as well as cellular analyses of lymph node tissue and peripheral blood will be determined in samples taken during the trial. The primary effect parameter is the effect of a single intralymphatic allergen injection on immunological parameters as well as allergen delivery to the lymph node as compared with a single subcutaneous injection.

Most asthma is allergic in origin. The purpose of this study is to better understand the airway immune response to inhaled allergens in order to identify factors that promote asthma.
