Filter by:The aim of this clinical trial is to compare the positive predictive value of the combination rapid nasal provocation test (RNTP) + skin tests (TC) + specific immunoglobulins E (IgEs) to the combination of TC + IgEs (strategy currently used in clinical practice) concerning the efficacy of treatment with Allergen immunotherapy (ITA) at 1 year, in patients with symptoms suggesting allergic rhinitis to house dust mites.
In Latin America and the Caribbean, more than 100 million people are exposed to higher levels of pollution than those recommended by WHO. The objective of the study is to determine the relationship between exposure to environmental pollutants and the prevalence and exacerbation of respiratory allergy. It is an observational, prospective, longitudinal and descriptive study that will include subjects older than 6 years who come to the consultation of the Regional Center for Allergy and Clinical Immunology with a diagnosis of respiratory allergy, positive skin tests and who live in Monterrey and its metropolitan area. After verbal assent, the subject's address and work area will be registered, the Rhinitis Control Assessment Test and the Asthma Control Test as well as spirometry will be made. The geolocation of industries and avenues near the address and work area of subjects will be carried out, as well as the determination of pollutants and pollens by the Integral Monitoring System (SIMA) and the Pollen Sense device. Subsequently, the correlation between exposure to pollutants and respiratory allergy will be analyzed. Dispersion models will be built considering pollutants and climatic factors (precipitation, wind speed, humidity and temperature). By carrying out this project, it will be possible to contribute to the identification of the factors that lead to the development and exacerbation of allergic respiratory diseases and subsequently propose the implementation of measures for their control and recommendations for prevention to the population.
Rhinitis medicamentosa (RM) is a form of non-allergic medication-induced rhinitis characterised by nasal congestion. This nasal congestion is the result of the overuse of intranasal decongestants which leads to rebound congestion when the medication wears off. This prompts the user of the nasal decongestant to administer more in order to obtain relief from the feeling of a blocked nose. Therefore, the patient ends up in a vicious cycle caused and temporarily relieved by the use of medication.The diagnosis of rhinitis medicamentosa depends greatly on the history of prolonged use of the nasal decongestant, since real diagnostic criteria have not yet been established. It is unclear if these patients suffer from an underlying (undetected and/or untreated) nasal condition which might have caused the patient to start using the nasal decongestant in the first place. Therefore, the aim of the first part of this study (Part A) is to characterize patients with long-term use of nasal decongestants to examine if an underlying nasal condition is present. The investigators will include healthy volunteers in part A of the study to be able to compare their test results with those of patients with long-term use of nasal decongestants and hence be able to detect differences. Thus far, the treatment of RM has been the topic of debate. Several treatment regimens have been proposed in literature, but most study authors agree that it is essential to stop the overuse of the nasal decongestant either immediately or gradually to limit withdrawal symptoms. For this part of the study (Part B: intervention study), the investigators aim to reduce the long-term use of nasal decongestants based on a structured withdrawal programme comprising medication (nasal corticosteroid spray) and motivational interviewing. Only patients with long-term use of nasal decongestants are eligible to participate in this part of the study. They will be rescreened prior to inclusion into this part of the study.
A Randomized, Double-Blinded, Placebo-Controlled, Prospective, Multicenter Clinical Trial to Evaluate the Efficacy and Safety of Subcutaneous Immunotherapy in Patients With Rhinitis With or Without Mild to Moderate Asthma Sensitized to cupressaceae and grasses.
Prospective, multicenter, randomized, double-blind, placebo-controlled clinical trial of efficacy and safety with subcutaneous immunotherapy in patients with mild to moderate rhinitis / rhinoconjunctivitis with or without mild to moderate asthma sensitized to grasses and olive
IgE-associated allergy is a hypersensitivity disease affecting more than 40% of the population in industrialised countries. Recently the kinetics of change of clinical and immunological parameters (e.g. nasal blockage and cytokine profiles) in response to allergen exposure have been described. Additionally through recent placebo controlled studies it has become clear that the response of certain cytokines can not only be triggered by allergen exposure but also mechanically e.g through the insertion of nasal swabs for collection of cytokines. However it is not clear to what extent the mechanically triggered cytokine responses may differ between healthy, allergic and asthmatic patients who have been shown to have different cytokine profiles in their nasal secretions and varying impairment of their respiratory epithelium. As collection devices for nasal secretions are frequently used in clinical studies, the investigators aim to assess the impact of mechanical stimulation by frequent cytokine sampling on the cytokine profile.
This is a phase 4 study to evaluate the the efficacy of second generation antihistamine on cough outcomes in cough patients with allergic rhinitis.
Prospective, randomized, placebo-controlled, multicenter of 3 active treatment groups, compared to 1 placebo group, for the determination of the efficacy and safety of subcutaneous immunotherapy in patients with mild to moderate asthma and allergic rhinitis/rhinoconjunctivitis (intermittent or persistent) due to hypersensitivity to house dust mites (Dermatophagoides pteronyssinus and / or D. farinae) and grass pollen
The aim of the study is to investigate the long-term effect of a lozenge containing beta-lactoglobulin (BLG), iron, retinoic acid, zinc and polyphenols (holo-BLG) in people with allergic rhinoconjunctivitis caused by house dust mites and the associated symptoms (symptom type and severity) during exposure to house dust mites in an Allergen Exposure Chamber (AEC). In particular, the study aims to evaluate whether the improvements in symptoms of house dust mite-induced rhinoconjunctivitis observed after 3 months of supplementation with holo-BLG can still be detected 7 to 8 months after the last intake.
Allergic rhinitis (AR) is a chronic inflammatory disease that affects almost 30% of adult population. Some patients associate septal deviation, main cause of chronic nasal obstruction, and AR. Current literature about AR treatment with septoplasty (STP) is still contradictory, because is thought that patients with AR are not able to appreciate improvement after surgery. Patients diagnosed with allergic rinitis and septal deviation were evaluated to determined life quality and airflow obstruction evolution after STP.
