A Biorepository of Multiple Allergic Diseases (MADREP) With Longitudinal Follow-Up
- Conditions
- Allergy, Sinus Disorders, Atopic Diseases, Asthma, Allergic Rhinitis, Atopic Dermatitis, EoE, Drug a
- Registration Number
- NCT06732414
- Brief Summary
Background:
Allergic or sinus diseases can affect the skin, sinuses, airways, and other parts of the body. Examples include pollen and environmental allergies, food allergies, asthma, and eczema. To learn more about how to prevent and treat these diseases, researchers need to study data, blood, fluid, and tissue samples from people affected by them.
Objective:
To collect data, blood, fluid, and tissue samples from people with allergic or sinus diseases.
Eligibility:
People aged 3 to 100 years with allergic or sinus diseases.
Design:
Participants will have at least one clinic visit, and most participants will have a baseline visit, annual visit, and an end of study visit. The duration of the study is 1 to 3 years. During the first clinic visit, the following procedures will be done to collect data, blood, fluid, and tissue samples:
* Blood will be collected.
* Cells and fluid may be collected from the inside of the nose using a long swab, and a small piece of skin may be scraped from inside the nose.
* Skin cells will be collected by rubbing with a cotton swab.
* A urine sample will be collected.
* Allergy skin prick tests. Allergy-causing substances will be placed on the back or arm and the skin underneath gently scratched. If the participant is allergic to the substance, the skin may become red, itchy, and swollen locally ( at the site of the test).
* Lung function test. Participants will breathe into a machine that measures the air moving in and out of their lungs.
* If, as part of their routine care, participants are undergoing procedures such as having nasal polyps removed, skin tissue samples taken, or gastrointestinal biopsies, additional tissues may be collected for this study.
* Participants will complete online questionnaires regarding their symptoms, health, and life.
Participants may return for more visits for up to 3 years.
- Detailed Description
Study Description:
This is a single-site repository study that will prospectively collect samples and data from participants with allergic and atopic diseases and associated conditions such as chronic rhinosinusitis and nasal polyposis, through the evaluation, testing, and monitoring of patients with these conditions at the NIH Clinical Center (CC) and via telehealth visits and/or send-in samples. This repository will provide atopic participant samples for translational studies performed by NIH investigators or their collaborators and also serve as a means for recruiting atopic control patients to ongoing NIAID and National Institute on Deafness and Other Communication Disorders (NIDCD) clinical studies.
Participants aged 3 and older will present to the NIH CC for visits for clinical evaluation and treatment of allergic diseases as appropriate. Data and samples obtained but not utilized from clinically indicated procedures will be put into the repository (e.g. physical exams, nasal endoscopy, blood tests, olfaction assessment, and nasal sinus polyp biopsy where appropriate).
Samples that may be collected prospectively for inclusion in the repository include nasal brushings, nasal lining fluid, blood, urine, and skin swabs. Additionally, extra skin, nasal sinus polyp, and gastrointestinal biopsies may be collected during clinically indicated procedures. The following assessments will also be performed for research purposes: Data collected from patient reported outcomes (PROs) and questionnaires, blood, urine, allergy skin prick testing, skin swab, and pulmonary function testing to include fractional exhaled nitric oxide testing (FeNO). Data/samples from clinical procedures will also be collected for the repository, where possible.
Although standard of care treatment may be initiated and monitored under this protocol, it will be expected that after a set number of visits outlined in the manual of operations, continued medication prescribing and monitoring will be transitioned to the referring provider, the patient s outside primary physician or allergist-immunologist, or another NIH protocol depending on the patient condition and importance for biorepository collection. No experimental treatments will be offered under this protocol.
Objective:
To create a repository of clinical, laboratory, and diagnostic data and specimens from a cohort of suspected or confirmed atopic or allergic individuals with diverse disorders seen by allergist-immunologists and rhinologists.
