Gore Tex Implants in the Treatment of Atrophic Rhinitis
Atrophic RhinitisThis is a retrospective study, involving patients with atrophic rhinitis, that underwent Gore tex® implants in the nasal fossa. The Fetid Rhinitis or Atrophic Ozena is a chronic illness characterized by yellowish secretion in the initial phase and the other phases with fetid crusts and atrophy of the mucous bone covering. Diverse theories exist that try to explain the appearance of this pathology, such as: hereditary factors, immunological alterations, viral infection and nutritional lack. Currently, its etiology remains unknown. As there isn't any ideal treatment already established, this technique improves the options of treatment. All patients have improved after the procedure.

House Dust Mite Allergen Reduction in Bedding: Purotex Impregnated Covers of Bekaert Textiles
Allergic RhinitisProduct information: Purotex is a textile treatment that uses five 100% natural bacteria or probiotics, selected for their ability to clean up house dust mite allergen along with other allergen types. Study design: Placebo-controlled: the effect of the Purotex impregnated mattress and pillow covers will be compared to untreated, classical bedding covers (placebo). Cross-over design: There will be 2 'treatment' arms. One arm (Arm 1) in which the subjects will first use the Purotex impregnated covers (Set A=Purotex) during 2 months (=period A) and, after a wash out period of 1 month, the untreated covers (set B=placebo) during 2 months (=period B). In the second arm (Arm 2), the subjects will first use the untreated set (set A=placebo) and, after a wash out period the Purotex impregnated covers (set B=Purotex). Randomized: The subjects will be randomly assigned to one of the 2 treatment arms. Double blind: both the subjects and the investigators will not know to which treatment arm the subjects are assigned. Study hypothesis: We want to investigate: if there is a reduced concentration of HDM allergen in Purotex covers compared to untreated covers in real life if patients with allergic rhinitis to house dust mite use the Purotex covers, they experience an improvement of their quality of life and sleep, and an improvement of their allergic symptoms and global discomfort

Primary Prevention of Atopic Disease by Perinatal Administration of Probiotics
Food AllergyAtopic Dermatitis2 moreAdministration of probiotics to pregnant women from an atopic family and subsequently to their high-risk newborns results in prevention of the incidence or in a decrease of the severity of atopic disease during infancy.

The Effects of OC000459 on Nasal Mediators
Allergic RhinitisThis is the first proof of concept study for OC000459 and is undertaken to assess the effects of the compound on the development of inflammatory cytokines in a model (nasal allergen challenge model) that is validated and clinically safe and easy to conduct. OC000459 will be compared with placebo in the study. The study will be a randomised, double blind, placebo controlled, crossover evaluation of the effect of OC000459 on cytokine secretion induced by nasal allergen challenge. Male subjects with a known history of allergic rhinitis and screening positive to allergen will be included. After dosing with OC000459 or placebo, nasal allergen challenge will be performed and measurements made in the nasal fluids. Nasal symptom scores will also be recorded. Safety parameters will be monitored throughout.

AsthmaBronchial3 moreThe purpose of this study is to determine the protective effect of an approved medication on asthma and allergic rhinitis (inflammation of the mucous membrane of the nose) upon exposure to cats.

An Allergen BioCube (ABC) Study Evaluating the Onset of Action of Fluticasone Furoate Nasal Spray...
Allergic RhinitisThe purpose of this study is to evaluate the onset of action of fluticasone furoate nasal spray compared to olopatadine nasal spray and placebo nasal spray in reducing nasal allergic signs and symptoms following ragweed exposure in the Allergen BioCube (ABC) after single dose administration and six consecutive days of treatment.

Topical Allstate and Nasal Allergen Challenge
Allergic RhinitisThe purpose of this study is to see whether Allstate Nasal Spray when given in the nose is safe and can reduce the signs and symptoms of allergic rhinitis (hayfever).

Detection and Use of Nasal Nitrous Oxide and the Electronic Nose
Allergic RhinitisNon-Allergic Rhinitis1 moreIntroduction: Rhinitis, sinonasal polyposis (SP) and asthma are diseases whose pathogenesis is based on inflammation. This will determine the presence of disease, its evolution and its treatment. It is therefore very important to develop and validate methodologies that allow us to noninvasively detect inflammation of the airways. Thus, just as exhaled nitric oxide (FeNO) has been studied as an important non-invasive marker of inflammation of the lower airways, nasal nitric oxide (nNO) may be a good marker of nasal inflammation. Furthermore, the electronic nose is an electronic nanosensor device capable of detecting specific volatile organic compounds (VOCs) that can be used as a non-invasive biomarker of biochemical processes in different diseases whose pathophysiology is also based on inflammation. Objective: To determine reference values of nNO and different patterns of VOCs in healthy individuals, individuals with allergic rhinitis (AR) and non-allergic rhinitis and individuals with SP and asthma. Methodology: Prospective, controlled study. Four groups will be included: Healthy subjects, patients with AR, non-allergic rhinitis and patients with SP and asthma (n=252). Prick-test to pneumoallergens will be performed. Determination of FeNO, nNO, lung function tests, measurement of VOCs by the electronic nose and blood samples will be taken. Bilateral nasal endoscopy and sample collection using the technique of brushing of mucosa and the placement of filter papers, for the study of nasal cytology and mediators of inflammation.

Characterisation of the Nasal Microbiome in Patients With N-ERD
Aspirin Exacerbated Respiratory DiseaseChronic RhinitisChronic rhinosinusitis (CRS) with (w) and without (s) nasal polyps (NP) in its different shapes is currently affecting up to 16% of the total population of the United States and around 11% of the population in Europe. It may also be associated with a hypersensitivity to non-steroidal anti-inflammatory (NSAID) drugs in a syndrome called NSAID-exacerbated respiratory disease (N-ERD) characterized by highly recurrent polyps and concomitant asthma. The pathophysiological mechanisms especially with regards to the potential role of the microbiome in driving N-ERD are so far not fully understood. Here, the investigators plan to analyse the nasal microbiome in these patients and to compare it to nasal samples from CRSwNP and CRSsNP patients as well as healthy controls (in total 80 subjects). This will provide insights into potential differences in the microbiome as compared to other CRS patients and the impact of the microbiome in driving this disease.
