Filter by:The purpose of this study is to evaluate the efficacy and safety of probiotics eN-Lac® capsules (Lactobacillus paracasei GMNL-32) for the treatment of children with perennial allergic rhinitis(PAR).
The purpose of this study is to study the efficacy of allergen injection immunotherapy for allergic rhinitis by - symptoms score - medication score - quality of life - immunologic test from blood
The investigators are investigating the early and late responses to allergen challenge. The research participants who the investigators will study (from three cohorts) will be part of independently-approved studies involving allergen challenge. Due to the uniqueness of the cohorts for novel genetic study, it is logical that the investigators should initially undertake hypothesis-generating experiments. The investigators will obtain blood samples from the participants, both pre-challenge and post-challenge. The investigators will determine gene expression and protein differences between these samples, and investigate if there are inherited genetic differences between individuals that may predict their specific responses to allergens.
What happens in the nose during an allergic reaction? Are there changes that a new drug could treat? What is the best way to test new drugs?The response of the nose to being exposed to cat allergen in someone who is allergic to cats. Symptoms, level of nasal blockage and cell and chemical changes that occur in the nose will be studied before and after being exposed to cat allergen. The investigators will also to see if giving repeated doses of allergen increases the response.Allergic rhinitis is a very common illness. There are over 500 million patients worldwide. It can increase the severity of associated asthma. Currently available drugs do not completely treat the symptoms. New treatments need to be found. A way of testing these drugs is very important. This study will investigate causes of the symptoms that occur in allergic rhinitis. It will also validate a proposed model to test new drugs. the Study Hypothesis is that a model of nasal allergen challenge shows an increased response (priming) with repeat challenges as determined by changes in nasal peak inspiratory flow.
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 purpose of this study is to verify and validate the intrinsic diagnostic value in terms of sensitivity and specificity of proteomic profiles determined during a pre-study for discriminating between allergy related asthma and allergy related 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.
This study will determine the capacity of more frequent dosing of QAV680 to suppress allergic inflammation. The study will investigate the paradigm of multiple receptor antagonism in allergic disease by combining QAV680 with a second generation H1 histamine receptor antagonist to assess possible additive or synergistic anti-allergic effects of the two compound classes.
The aim of the study is to show an improvement of quality of life on the 5th week of product consumption (probiotic Lactobacillus paracasei LP-33)(as assessed by RQLQ global score) in subjects with persistent allergic rhinitis currently treated with Loratadine or oral anti-histaminic treatment.
The purpose of this cross-sectional survey study is to describe the prevalence of asthma and Rhinitis symptoms among secondary school students in Saudi Arabia.
