Establishment of Biobank of Nasal Epithelium Samples From Healthy Volunteers

Official title

Establishment of a Biobank of Nasal Epithelium Samples From Healthy Volunteers

Overview

Background: Infections in the lower respiratory tract (lungs) are the leading cause of death from infectious disease worldwide. This was true even before the COVID-19 pandemic. Respiratory viruses are still a major health threat. Many of these viruses infect people by penetrating the thin skin that lines the nose. These viruses can also spread easily to other people when they multiply in the tissues that line the nose. Researchers want to learn more about what these viruses do inside the nose, how they get from the nose to the lungs, and how they spread from person to person. Objective: To collect cell samples from inside the noses of healthy people. These cells will be stored for use in future research on respiratory diseases. Eligibility: Healthy volunteers aged 18 years and older. Design: Most participants will have 1 visit on 1 day. They will be asked questions. Those who have a runny nose, coughing, congestion, or fever will be asked to wait up to 21 days before participating. Participants will be given a slender swab with small bristles at the end. They will rub the inside of their nose with the swab. A clinic staff member will be present to help, if needed. Participants will provide their name, age, and sex. This information will be encoded so that only certain researchers will know the participants identities. Participants will not be contacted again....

Detailed description

Study Description:

This is a repository protocol with prospective sample collection to provide samples needed for future studies of the pathogenesis of emerging respiratory viruses. Nasal brushings will be collected from approximately 100 healthy volunteers at RML and stored in the LV to be made available for future research studies that will be conducted under separate protocols, as applicable.

Primary Objective:

To obtain nasal epithelium brushes from healthy volunteers for 1) establishment of upper respiratory tract organoids, 2) assay validation, and 3) use for research into the pathogenesis of emerging respiratory viruses.

Primary outcome measures

• To obtain nasal epithelium brushes from healthy volunteers for 1) establishment of upper respiratory tract organoids, 2) assay validation, and 3) use for research into the pathogenesis of emerging respiratory viruses. [Time frame: 10 years]

Eligibility criteria

• INCLUSION CRITERIA:

In order to be eligible to participate in this study, an individual must meet all of the following criteria:

• Aged >=18 years.
• Able to provide informed consent.
• Willing to allow biological samples and data to be stored for future research.

Exclusion criteria

An individual who meets any of the following criteria will be excluded from participation in this

study:

• History of respiratory symptoms including but not limited to runny nose, coughing, congestion, and/or fever within the past 14 days.
• NIH and laboratory staff with direct involvement in the operation or maintenance of the repository are excluded from participation.
• An individual who has any condition that, in the judgment of the investigator, may put them at undue risk or make them unsuitable for participation in the study will be excluded.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
