Filter by:The prevalence of allergic diseases (atopic dermatitis, asthma, rhinitis, conjunctivitis and food allergy) has increased dramatically in industrialized countries over the last 20-30 years. Allergic diseases are present especially in children and young adults, but all age groups are affected, with variations across countries and age. To propose new therapies, the investigators must first understand the physiopathology. Since their discovery the regulatory T cells have continued to be the subject of work to understand their role in maintaining immune homeostasis in the human body but also their involvement in autoimmune diseases, inflammatory diseases, transplants of solid organs or fluids and allergic diseases. It was identified two broad classes of regulatory T cells: - T cells = natural regulators acquisition of a phenotype and a regulatory function right out of the thymus ( CD25 + / CD127 + low / FoxP3 +). - T cells induced regulators = acquisition of a phenotype and a regulatory function on the periphery depending on the cytokine micro-environment. Phenotypic characterization of these is less obvious and even more so than during the last ten years several induced regulatory T cell populations have been described ( eg, Tr1 ). A new subpopulation of T cells induced in patients with inflammatory bowel disease recently identified have a particular phenotype as bearing the CD4 and CD8 double marking with a regulatory phenotype. These regulatory T cells are also induced a specific of a commensal intestinal bacterium (Faecalibacterium prausnitzii). Regarding allergies, it has been widely demonstrated a relationship between changes of the intestinal microbiota and the occurrence of allergic diseases. The investigators would therefore propose a cross-sectional study, single-center, controlled, single blinded to study the role of T cells called double positive induced regulators DP8 to compare the frequency and the regulatory function of specific DP8 of Faecalibacterium prausnitzii in atopic dermatitis, asthma and allergic rhinitis compared to control samples.
Allergic rhinitis is a common illness suffered among US Veterans. There are medications that help relieve allergy symptoms, including nasal steroid sprays and antihistamines. Some patients have increase symptoms with exposure to their trigger, such as a grasses when combined with pollution due to oxidative stress from pollution. In this study, patients with allergic rhinitis to grass will be given broccoli sprout extract that contains an antioxidant sulforaphane do see if there is beneficial effect in these patients.
Nasal symptoms are the main elements that lead to a therapeutic decision and allow for evaluating treatment effects or natural evolution. Despite availability of several questionnaires with good measurement qualities, no systematic assessment takes into account the specific physical and psychosocial consequences of each of the six main nasal symptoms, independently of the disease. The study proposed to measure these symptoms with the use of a selfreport questionnaire and to test the validity of the questionnaire in a large representative sample of patients attending outpatient rhinologic clinics.
Study to evaluate the efficacy, safety and tolerability of GSP 301 NS compared with placebo NS and individual monotherapy formulations for the treatment of Seasonal Allergic Rhinitis (subjects 12 years of age and older)
The investigators will evaluate sensitization to animal allergens and allergic symptom during contacting animal allergens in Korean veterinary researchers who attend their annual conference. The investigators will compare sensitization to animal allergen and other clinical and occupational factors between subjects who suffer from allergic symptom during contacting animal and those who do not.
The purpose is to obtain real-world information on how consumers are complying with the product labelling This study will coincide with the launch of Pirinase Hayfever Relief for Adults 0.05% Nasal Spray in the United Kingdom (UK).
This is an observational prospective study to assess the tolerability and safety of treatment of SCIT Allergovac Poliplus polymerized in depot presentation. The study drug will be administered either by a 1 day Schedule or by a rapid Schedule (3 increasing weekly doses at initiation period till maintenance dose is reached) The study population is both: adult and child, polysensitized to at least 2 allergen sources with rhinitis or allergic rhinoconjunctivitis. Patients may also present a concomitant mild or moderate asthma. The assignment of a patient to a particular therapeutic strategy will not be decided in advanced by a trial protocol but will be determined by routine clinical practice. The decision of the investigator to prescribe a particular treatment will be clearly dissociated from the decision to include the patient in the study. The patients will not suffer any intervention, whether diagnostic or monitoring, other than the usual in clinical practice.
This is a pilot cross-sectional study of measured transcutaneous CO-oximetry in children with inflammatory and non-inflammatory conditions.
This is a single-arm pilot study designed to evaluate the feasibility of cryoablation in the nasal passageway, using the ClariFix device, to reduce the symptoms of chronic rhinitis.
Allergic rhinitis is a common condition that affects adults as well as children and adolescents, often with impaired quality of life. Patients often report a poor level of satisfaction with the effectiveness of their treatment and are always looking for more drug combinations to improve their symptom. Several tools exist for assessing control of allergic rhinitis, but none has been validated in adolescents or in children. A study conducted in 2008, resulted in the validation of a self-administered control test of allergic rhinitsis (ARCT) in patients from 12 years of age. However, this study included only 67 adolescents aged 12 to 17 years old and lacked power. In this new study,the investigators propose, following exactly the same procedure as the pilot study of 2008, to confirme the validation of unmodified Adult questionnaire in adolescents 12 to 17 years inclusive.
