What this trial studies

This study aims to collect data and biological samples from individuals aged 3 to 100 years who have allergic or sinus diseases. Participants will undergo clinical evaluations and provide samples such as blood, nasal fluid, and skin swabs during their visits to the NIH Clinical Center. The collected samples will be stored in a biorepository for future research on allergic conditions and may also be used to recruit control patients for ongoing clinical studies. The study will last between 1 to 3 years, with participants having at least one clinic visit and potentially annual follow-ups.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 3 to 100 years with suspected or confirmed allergic or atopic conditions.

Not a fit: Patients without any allergic or atopic conditions or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding and treatment options for various allergic diseases.

How similar studies have performed: Other studies have successfully utilized biorepositories for allergic diseases, indicating a promising approach.
