Filter by:While allergen specific immunotherapy (SIT) is highly effective for allergic diseases in children, the underlying immunological mechanisms are unclear. Regulatory T (Treg) cells may be crucial in induction of tolerance. Our aim was to investigate the role of CD4+CD25+Foxp3+ T cells and IL-10-secreting type I T regulatory (Tr1) cells in the response to one year of cluster SIT to Dermatophagoides pteronyssinus for allergic rhinitis in children. CD4+CD25+Foxp3+regulatory T cells and IL-10-secreting type I T regulatory (Tr1) cells were analyzed in children allergic to Dermatophagoides pteronyssinus during one year cluster specific immunotherapy (SIT) in a prospective and randomized study. Peripheral blood mononuclear cells (PBMCs) were collected from 25 children receiving SIT and 21 receiving pharmacotherapy. The frequencies of CD4+CD25+Foxp3+ T cells and allergen-specific IL-10+IL-4-, IFN-γ+IL-4-, IL-4+IFN-γ-CD4+ T cells were measured by flow cytometry. Production of IL-4, IFN-r, and IL-10 in supernatants from allergen-stimulated PBMC culture was measured by ELISA. Finally, the suppressive effect of CD4+CD25highTreg cells from both groups was estimated.
This is an open-label, randomized, multicenter, 2-way crossover study in subjects 12 years or older with perennial allergic rhinitis (PAR) to evaluate the psychometric properties of a novel-patient administered assessment of treatment satisfaction with and preference of an Internasal Corticosteroid (INCS)
Background: Nasal allergen challenge (NAC) is useful to study the pathophysiology of rhinitis, and multiple challenges may more adequately approximate natural exposure. Objective: To determine the effect of 4 consecutive daily NAC, on clinical and inflammatory parameters in rhinitics with or without asthma.
The purpose of this study is to determine whether a neuropeptide, substance P, when injected along with an allergen, such as ragweed, can reduce allergic reactivity.
This study compared the safety and efficacy of a generic fluticasone furoate (Lek Pharmaceuticals) nasal spray to the reference listed drug in the treatment of seasonal allergic rhinitis. Additionally both the test and the reference formulations were tested for superiority against a placebo nasal spray.
This is an efficacy study of bepotastine besilate nasal spray in seasonal allergic rhinitis.
There is inconclusive evidence whether acupuncture treatment is effective in the treatment of seasonal allergic rhinitis (SAR). Furthermore, the underlying mechanisms of acupuncture in SAR are only poorly understood. It was hypothesised that the therapeutic mechanism of acupuncture is related to changes in autonomic function. AUTO-ACUSAR is a sub-study of the DFG-funded three-arm randomized controlled trial ACUSAR trial investigating the efficacy of acupuncture vs. sham acupuncture vs. rescue medication in SAR. The aim of AUTO-ACUSAR was to investigate short and long-term effects of acupuncture vs. sham acupuncture on autonomic function in a sub-group of ACUSAR patients. Baseline values were compared to data from matched healthy controls.
Allergic rhinitis is an IgE-mediated, inflammatory disorder of the upper airway that occurs following allergen exposure. Perennial Allergic Rhinitis (PAR) starts in early childhood and occurs all year around. It's caused by allergy to the aerosolised droppings of house dust mites and pet skin flakes (dander). Occasionally, indoor mould spores and, in rare cases, food allergy can be causes. Intranasal corticosteroids are highly effective medications for controlling the nasal symptoms that accompany allergic rhinitis. AVAMYS (TM) (fluticasone furoate aqueous nasal spray 100mcg) has been shown having effects on nasal symptoms of seasonal and perennial allergic rhinitis and on the ocular symptoms of allergic rhinitis and has been evaluated as effective and safe for treatment seasonal and perennial allergic rhinitis by FDA. It is speculated that AVAMYS (TM) is also effective and safe for Vietnamese patients. However before being used widely for patients across the country, AVAMYS (TM) should be proved that it is safe for Vietnamese patients. The objective of this study is to evaluate the safety of fluticasone furoate aqueous nasal spray 110mcg once daily in adults with PAR. This is a 6-week, open trial. A study center will be enlisted to recruit a minimum of 50 PAR subjects. At the visit 1, subjects who fulfill the inclusion criteria are eligible to be included in the group to self-administer intranasal treatment of fluticasone furoate aqueous nasal spray 110 mcg once daily for 6 week. The subjects are instructed to administer two sprays from the device into each nostril once daily every morning. Administration of the dose will be performed by alternately spraying one spray to each nostril followed by a second spray to each nostril. Subjects will not be permitted to take any anti-allergy or rhinitis medication during the screening or treatment period. Throughout the study, subjects will document their study drug administration/compliance, any medical conditions experienced, and any concomitant medications taken. All subjects are outpatients. The safety assessments include a summary of the frequency and type of clinical adverse events that occur during the study. In addition, hematology and chemistry analyses of blood samples are also implemented. A physical examination and nasal examination are also performed and vital signs collected. Twelve-lead ECGs are performed at all visits.
The purpose of this study is to see if a nasal steroid drug delivered to the nose with the NasoNeb™ inhaler improves the symptoms of people with perennial allergic rhinitis (year round allergy symptoms).
The purpose of this study is to explore the activity of UR-63325 in a model of allergic rhinitis induced by nasal allergen challenge to known allergic rhinitis patients otherwise healthy.
