Filter by:Recently, interest has increased in sublingual immunotherapy (SLIT) for treating allergic rhinitis. It is often suggested that polysensitized patients might not benefit from specific immunotherapy as much as monosensitized patients, although further research on this subject is needed. This study compared the efficacy of SLIT with standardized house dust mite extract in mono- and polysensitized allergic rhinitis patients. Patients who were sensitized to house dust mites and treated with SLIT for house dust mites for at least 1 year between November 2007 and March 2010 were included. The mono-allergen sensitized group (Mgr) was defined as the patients who were sensitized to Dermatophagoides pteronyssinus (Dp) or D. farinae (Df; n = 70). The poly-allergen sensitized group (Pgr) was defined as the patients who were simultaneously sensitized to house dust mites and other allergens (n = 64). A standardized extract of house dust mites was used for immunotherapy. Anti-allergic medication and the total nasal symptom score (TNSS), including rhinorrhea, sneezing, nasal obstruction, and itchy nose, were evaluated before and 1 year after SLIT. This study enrolled 134 patients. The TNSS improved significantly after SLIT in both groups, while the change in the TNSS did not differ significantly between the groups. The anti-allergic medication scores also decreased significantly in both groups, but there was no significant difference between the groups. In polysensitized allergic rhinitis patients, SLIT for Dp/Df gave comparable improvements in both nasal symptoms and rescue medication scores to those in monosensitized patients, regardless of other positive allergens. SLIT for Dp/Df might be considered in polysensitized allergic rhinitis patients.
Primary Objective: - To evaluate safety (4 weeks) Secondary Objectives: - To evaluate the long-term safety (12 weeks) - To evaluate the efficacy - To characterize the pharmacokinetic profile
This study will assess the efficacy and safety of different doses of ACT-129968 in adult patients with seasonal allergic rhinitis, due to mountain cedar pollen.
Various studies in animal and humans have shown a potential beneficial effect of probiotics consumption on allergy. However few studies exist that document their efficacy for upper airways allergies such as allergic rhinitis. The objective of this study is to investigate the effect of short-term oral administration of a L. paracasei or of a blend of 2 probiotics (L. acidophilus + B. lactis) on a nasal provocation test (NPT) with grass pollen, performed out of the pollen season. Adult volunteers with allergic rhinitis are enrolled in a randomized, double-blind study, based on two 4-weeks cross-over periods of product consumption separated by a washout period of 6-8 weeks. Objective and subjective clinical parameters of NPT as well as systemic and nasal immunological markers are compared before and after each treatment.
The objective of this study is to compare the efficacy and safety of Fluticasone Furoate Nasal Spray (FFNS), that is FFNS with placebo in Chinese adult and adolescent subjects with Allergic Rhinitis as AR. There are 3 phases, 2 to14 day run in, 2 week treatment, and 3 to 5 day follow up. After run in period, at least 360 subjects with AR ( ages of 12yrs and 65yrs, inclusive) will be randomised to receive FFNS 110ug once daily or placebo for 2 weeks. The primary endpoint is the change from baseline of reflective total nasal symptom score (rTNSS) during treatment period, and the secondary endpoints include mean change from baseline in nasal finding scores by rhinoscopy at completion of study treatment, and severity of overall inference in activities of daily living. Safety measures include AE (Adverse Event) reports, ECGs (Electrocardiograph), physical exams, vital signs, and nasal exam. In addition, reflective total ocular symptom score (rTOSS) will be measured as an explorative endpoint, only in the specific AR (Allergic Rhinitis) patients with severe ocular symptoms.
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 loratadine-pseudoephedrine combination has proven to be more effective than the use of these individual components. This prospective, randomized, double-blind and paralel study, in which patients with perennial allergic rhinitis receive one of loratadine + pseudoephedrine association drug for treatment of signs and symptoms during 4 weeks.
The term idiopathic rhinitis (IR) is used in this study to describe a patient group with following characteristics: patients with complaints of nasal obstruction, sneezing and/or rhinorrhea for a period of over 1 year, which cannot be attributed to allergy, nasal or paranasal infection, anatomical disorders, pregnancy or lactation and/or systemic disorders. These patients are non-smokers and do not use medication affecting nasal function. They have no beneficial effect of intranasal steroid spray (INS) treatment. The population incidence of IR is estimated to be as high as 10%. The pathophysiology of IR is largely unknown. Several hypotheses have been put forward. In general it is assumed that neurogenic mechanisms play an important role. Neuropeptides like CGRP, SP, NKA/B, NPY, NGF are released from afferent neurons in the nasal mucosa after activation by unspecific stimuli and can be responsible for the symptoms of IR. For this group of IR-patients, there is until now only one treatment option: intranasal capsaicin application. Capsaicin, the pungent agent in hot pepper, is supposed to exert its' therapeutic effect via degeneration or desensitization effect on the afferent C-fibers. The hypothesis is that nasal capsaicin treatment reduces neurogenic inflammation and reduces in that way nasal symptoms.
The purpose of this study is to examine the safety and efficacy of bepotastine besilate nasal product in seasonal allergic rhinitis patients.
This trial is a biomarker-based pilot study of the safety of Cockroach Subcutaneous Immunotherapy in Cockroach-sensitive Adults (SCITCO) who have a history of perennial allergic rhinitis, asthma, or both.
