Filter by:Background: A nasally applied cellulose powder is increasingly used in many countries as a remedy for allergic rhinitis. In 2009, a 4-week study in birch pollen-allergic children showed a reduction in nasal symptoms. The best effect occurred on days with lower pollen counts. The present study in grass pollen-allergic adults used the same basic design. Methods: In May 2013, a double-blind, placebo-controlled study was conducted in 108 patients with allergic rhinitis due to grass pollen (18-40 years of age). SMS on mobile phones were used as reminders of treatment and reporting of symptom scores.
Questionnaire to measure and control the quality of life of patients with hay fever who are treated or were treated with Pollinex quattro
This study is to assess the onset of action of fixed drug combination of azelastine hydrochloride and fluticasone propionate nasal spray (MP-AzeFlu) in treating the nasal symptoms of seasonal allergic rhinitis (SAR) induced by an allergen challenge in an Environmental Exposure Chamber (EEC).
The study evaluates the safety and effect of intralymphatic allergen specific immunotherapy in increasing doses. Patients with allergy to grass or birch will be treated with three intralymphatic injections in an up-dosing protocol; 1000 SQ-U, 3000 SQ-U and 10 000 SQ-U, or placebo. ***IMPORTANT INFORMATION!*** The up-dosing protocol is changed due to adverse events at 5000 SQ-U. One patient had general utricaria 15 minutes after injection (moderate reaction). One patient had a serious adverse event with anaphylactic reaction 6 minutes after intralymphatic injection. (1000 SQ-U and 3000 SQ-U have been given with no serious adverse events.) New regimen: 1000 SQ-U, 3000 SQ-U, 3000 SQ-U.
A multicentre, Double-blind, Placebo-Controlled, Randomized Trial to Assess the Efficacy and Tolerability of Two Dosing Regimens of AllerT, a Combination of Contiguous Overlapping Peptides Derived from Bet v 1, in Adults with Birch Pollen Allergic Rhinitis/Rhinoconjunctivitis
The objective of this clinical trial was to assess the efficacy and safety of cetirizine HCl syrup vs. loratadine syrup vs. placebo syrup in the treatment of SAR in children 6 to 11 years old.
Rhinovirus (RV) infections represent the most common cause of asthma exacerbations in children and adolescents. The investigators hypothesize that the immune responses generated in the nose of allergic rhinitics and asthmatics underlie subsequent systemic modulation of the immune system, and that - in susceptible individuals (i.e., those with pre-existing asthma) - this modified nasal milieu is responsible for the asthma exacerbation. Open label single center study in asthmatics as well as allergic rhinitis (AR) and healthy controls. All subjects will undergo good manufacturing practice (GMP) RV16 inoculation and responses will be compared between the 3 cohorts.
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.
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)
