Active clinical trials for "Rhinitis, Allergic"

The purpose of this study is to evaluate development of allergic rhinitis in children with nonallergic rhinitis.

The purpose of this study is to establish whether MRI scanning is a sensitive measure of the effects of existing drug treatments on nasal dimensions following challenge with intranasal allergen in subjects with hayfever. If successful this technique could be applied to increase confidence for internal decision making and ultimately may be used to assess how effective a new drug treatment is.

The objective of this study is to determine whether there is a relationship between interferon-gamma levels and the incidence of viral respiratory infections in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care (nasal steroids, antihistamines) over a 1-year period. The hypotheses to be tested are 1) interferon-gamma levels will be significantly increased 3, 6, 9 and 12 months in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care, 2) the incidence of viral respiratory infections will be reduced at 3, 6, 9 and 12 months in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care.

Seasonal/perennial allergic rhinitis (SAR/PAR) is a common childhood illness. One of the leading therapies for the treatment of SAR/PAR is intranasally inhaled corticosteroids (ICS). One of the major long-term safety concerns is whether ICS interferes with normal growth in allergic rhinitis children. Recent evidence suggests that nasal ICS may cause decreased growth. However, the effect of nasal ICS on long-term growth and the attainment of final adult height is unknown. Another potential systemic adverse effect of ICS use is suppression of the hypothalamic-pituitary-adrenal axis function. The primary hypothesis of this study is that triamcinolone acetonide aqueous nasal spray (TAA) will have no effect on measured adult height in relation to target adult height in children with allergic rhinitis.

In this study, investigators evaluated for the first time the diagnostic efficacy of abioSCOPE® versus Phadia Laboratory System as an aid in the diagnosis of allergic diseases. Investigators targetted the agreement between test results obtained in abioSCOPE® and a laboratory reference method (Phadia Laboratory System, ThermoFisher Scientific, Uppsala, Sweden), considered as a quasi-gold standard in IgE (immunoglobulin E) antibody assays. Investigators also reported the medical decision taken by a panel of allergy experts who had access to patient history, skin tests and IgE antibody assay, but blinded to the method used, i,e, the reference method or the abioSCOPE® .

This is an observational prospective multicenter clinical study, to evaluate the efficacy and safety of the treatment with Allergovac Poliplus subcutaneous immunotherapy (SCIT) with a mixture of 2 allergenic extracts (pollens or mites), in polymerized-depot formulation, administered in its different available allergenic extracts mixtures (2 pollens or 2 mites), and in one of the 2 recommended administration schedules (1 Day or Rapid).

Investigator examines the past prescription patterns and the reasons for the change of prescription to Monterizine capsules for Perennial Allergic Rhinitis patients with Asthma who will be taking Monterizine capsules to treat allergic rhinitis. After being given Monterizine capsules, Investigator evaluates the therapeutic effectiveness and safety for 3 months (or 6 months).

The aim of this study is to assess the nasal and conjunctival response in subjects allergic to birch pollen during controlled exposures in the ALYATEC environmental exposure chamber (EEC)

A validated mobile Allergen exposure chamber (AEC) is used to expose qualified study participants suffering from house dust mite (HDM) induced allergic rhinoconjunctivitis. A maximum of four individuals are exposed at a time under standardized conditions with a mixture of allergens from Dermatophagoides pteronyssinus and Dermatophagoides farinae (each 50%, faeces and body allergens; doses of 250 μg/m3 air; 21°C, and 55% relative air moisture). After the first exposure, a dietary supplement lozenge, containing beta-lactoglobulin (BLG), iron, retinoic acid, zinc and polyphenols, is taken twice daily for a period of 12 weeks, followed by the second exposure. A minimum of thirty persons are challenged with HDM allergen. After entering the chamber there is an acclimatization phase of 20 minutes with no exposure. Exposure time starts after acclimatization in the chamber and is 120 minutes at each visit. Objective parameters are recorded every 30 minutes, and subjective parameters are recorded every 10 minutes over a period of 120 minutes. During the exposure a plateau (steady-state) of total nasal symptom score with a difference from baseline is measured in all participants for each of the two exposures with HDM.

Allergic diseases in children are major public health concerns due to their widespread and rising prevalence. The most classic pathway to trigger allergy is type I allergy mediated by immunoglobulin E(IgE), but the role of immunoglobulin G4(IgG4) in allergic diseases is still worth exploring.we have collected the data of allergic patients aged 0-14 years for retrospective cross-sectional analysis to evaluate the positive rates of total IgE, HDM IgE, FS-IgE and FS-IgG4. Meanwhile, investigators screened out patients who were treated with FS-IgG4-guided elimination diets with/without probiotics for more than 3 months to clarify the role of FS-IgG4 in childhood allergic diseases by assessing the improvement of clinical symptoms before and after treatment.
