Active clinical trials for "Rhinitis, Allergic"

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.

The aim of this study is to investigate the immunomodulatory potential of Isolated Plasmacytoide Dendritic Cells (pDCs) and Regulatory T-cells (TREGs) isolated with clinical grade magnetic bead isolations techniques (MACS®) on the antigen presenting cell-induced proliferation of lymphocytes after allergen uptake in an in vitro cell culture system.

This is a post-marketing surveillance study on a marketed cetrizine hydrochloride formulation.

Allergic rhinitis is a common condition that affects adults as well as children and adolescents, often with impaired quality of life. Patients often report a poor level of satisfaction with the effectiveness of their treatment and are always looking for more drug combinations to improve their symptom. Several tools exist for assessing control of allergic rhinitis, but none has been validated in adolescents or in children. A study conducted in 2008, resulted in the validation of a self-administered control test of allergic rhinitsis (ARCT) in patients from 12 years of age. However, this study included only 67 adolescents aged 12 to 17 years old and lacked power. In this new study,the investigators propose, following exactly the same procedure as the pilot study of 2008, to confirme the validation of unmodified Adult questionnaire in adolescents 12 to 17 years inclusive.

This is an observational prospective study to assess the tolerability and safety of treatment of SCIT Allergovac Poliplus polymerized in depot presentation. The study drug will be administered either by a 1 day Schedule or by a rapid Schedule (3 increasing weekly doses at initiation period till maintenance dose is reached) The study population is both: adult and child, polysensitized to at least 2 allergen sources with rhinitis or allergic rhinoconjunctivitis. Patients may also present a concomitant mild or moderate asthma. The assignment of a patient to a particular therapeutic strategy will not be decided in advanced by a trial protocol but will be determined by routine clinical practice. The decision of the investigator to prescribe a particular treatment will be clearly dissociated from the decision to include the patient in the study. The patients will not suffer any intervention, whether diagnostic or monitoring, other than the usual in clinical practice.

The purpose of this study is to evaluate the immunomodulatory effect of treatment of allergic rhinitis symptoms with specific immunotherapy by measurement of pulmonary inflammatory markers, and among others, exhaled nitric oxide.

This study seeks to document differences in nasal irritant sensitivity within the population. The investigators are interested in knowing whether age, gender, and allergy status (nasal allergies) predict nasal irritant sensitivity. This is important in understanding symptom reporting patterns in air pollution situations (particularly in so-called "problem buildings"), as well as in understanding the reflex mechanism of a response of the nose to irritants (e.g., nasal congestion).

This study will evaluate and follow patients with various allergic, hypersensitivity and inflammatory disorders. The protocol is not designed to test new treatments; patients will be managed with standard of care therapies. Participants may be referred to other current NIAID protocols as appropriate or to new studies as they are developed, but will not be required to join another study. Patients with allergic, hypersensitivity or inflammatory disorders between the ages of 3 years and 80 years may be eligible for this study. Conditions of interest include, but are not limited to, asthma, allergic rhinitis, mastocytosis, atopic dermatitis and food allergy. Participants will have a medical history and physical examination, plus standard tests for diagnosing and treating their specific disorder. Tests may include routine blood and urine studies, X-rays or other imaging studies, allergy skin tests and lung function tests. Blood samples may be collected for research on immune system cells and other substances involved in immune function. Generally, about 2 to 6 tablespoons will be drawn at a time, but no more than 16 ounces will be collected over a 6-week period. NIH does not provide emergency medical treatment or treatment for other, unrelated conditions the patient may have. Therefore, patients must maintain a personal physician for these purposes.

Cysteinyl leukotrienes (CysLTs) play an important role in asthma. CysLTs exert most of their bronchoconstrictive and pro-inflammatory effects through activation of the CysLT1-r. As allergic rhinitis appears to be a predisposing factor in the development of asthma and as CysLT-receptors seem to be implicated in the first steps of asthma manifestations, we think it would be of interest to determine if the CysLT1-r is a key mediator in the progression from allergic rhinitis to asthma. We believe it would be interesting to study the expression of the CysLT1-r Our goal is to assess baseline, as well as variations following allergen bronchoprovocations, in the expression of the CysLT1-r in mild asthmatic subjects compared with non asthmatic subjects with allergic rhinitis. Our hypothesis is that there will be a higher baseline expression of the CysLT1-r in asthmatic subjects compared with allergic rhinitis subjects and that allergen bronchoprovocations will induce an increase in the expression of the CysLT1-r in both groups.
