Filter by:RV568 is being developed for the treatment of diseases such as asthma, COPD and allergic rhinitis (e.g. hayfever). The main aim of this study is to investigate whether RV568 ameliorates the nasal symptoms to low doses of grass pollen in healthy subjects with seasonal allergic rhinitis.
The purpose of this study is to determine the safety and tolerability of several doses of ragweed pollen allergen extract administered as sublingual tablets in subjects with allergic rhinitis to ragweed.
The purpose of this study is to examine the safety and efficacy of bepotastine besilate nasal product in seasonal allergic rhinitis patients.
Inflammatory proteins from eosinophil granulocytes in blood from patients with seasonal allergic hayfever have been shown to predict development of asthma at a six-year follow-up. This study is a 15-year follow-up of the same patients to verify earlier results and study disease development.
The purpose of this study is to determine the appropriate concentration of diagnostic reagent of house dust mite (Dp) to be used in diagnostic allergy skin prick test among Thai population with allergic rhinitis.
To report and compare total symptom scores, nasal symptom scores, post-nasal drip symptom scores, and adverse reactions in and between SAR subjects on active drug and SAR subjects on placebo.
In vitro studies reveal immunomodulatory effects of probiotic bacteria that are strain-dependent. Differential immunomodulatory in vitro capacities can not be extrapolated directly to in vivo efficacy. Thus, in vitro screening should be followed by comparative analysis of the selected immunomodulatory probiotic strains in an in vivo setting. Birch pollen allergy is one of the most common forms of respiratory allergy in European countries, and recognized by a Th2-skewed immune system. Five Lactobacillus strains will be evaluated for their immunomodulatory properties in birch pollen sensitive subjects outside the hay fever season. A double-blind placebo-controlled parallel study will be performed in which subjects with a proven birch pollen allergy will consume one of 5 different probiotic yoghurts containing 4 L. plantarum strains and 1 L. casei strain or a placebo yoghurt. Blood samples are collected at the start and after 4 weeks. Immune parameters are determined in serum and peripheral blood mononuclear cell cultures (hPBMC) derived from these subjects.
The study aims to examine the effect of probiotics on the clinical symptoms of allergic rhinitis and to elucidate some of the immunological mechanisms involved.
The objective of the study was to determine the efficacy and tolerability of 20 mg of Bilastine, compared to Desloratadine and placebo for the treatment of Seasonal Allergic Rhinitis.
The objectives of this study would be to see if the addition of vitamin D to fluticasone propionate provides greater symptomatic relief in patients with seasonal allergic rhinitis compared to fluticasone propionate treatment alone.
