About this study

Official title: The Effects of Exosomes in Children With Adenoid Hypertrophy Accompanied by Otitis Media With Effusion

The particularity of adenoids, as a reservoir of bacterial pathogens and immune molecules, is known to be significantly involved in children with otitis media with effusion (OME). As an important carrier of intercellular substance transfer and signal transduction, exosomes with different biological functions can be secreted by different types of cells. There remains significant uncertainty regarding the clinical transmitter of exosomes to OME, especially in its pathophysiologic development. In this study, the investigators try to elucidate the biological functions of exosomes in children with adenoid hypertrophy accompanied by OME.

Patients with adenoid hypertrophy or otitis media will be separated into three groups: those with adenoid hypertrophy, with otitis media and with adenoid hypertrophy and otitis media both, as well as a healthy control group. Participants in the four groups will have their middle ear effusion, nasopharyngeal secretion, and peripheral blood samples taken, from which exosomes will be separated for further analysis. Adenoidectomy will be conducted in adenoid hypertrophy accompanied by OME and adenoid hypertrophy alone and their adenoid tissue will be collected. Blood will be collected again 3 months after surgery and middle ear and nasopharyngeal examinations will be performed. Exosomes will be isolated for follow-up studies as before surgery. Investigators will also use proteome research, exosome biomarkers, and high-throughput sequencing to examine the pathophysiology of OME, particularly inflammation-related etiology, in order to provide novel ideas for OME diagnosis and treatment.

Read the detailed description

This study will explore the pathogenesis of OME by detecting the exosome in middle ear fluid, nasopharyngeal secretions and peripheral blood in order to identify areas of opportunity for future research and to provide a theoretical basis for drug development for the treatment of secretory otitis media.

240 subjects will be recruited from Eye and ENT hospital of Fudan University or the community. They will be divided into four groups: adenoid hypertrophy accompanied by OME (group OA, n=60), adenoid hypertrophy alone (group CA, n=60), OME alone (group CO, n=60) and healthy control group (children without OME or adenoid hypertrophy, n=60). All participants will undergo the examinations of middle ear and nasopharynx in addition to blood collection when they get into the groups. The exosomes will be isolated form middle ear effusions, nasopharyngeal secretions/adenoid tissue, and peripheral blood collected from all participants. The OA and CA groups will undergo adenoidectomy and their adenoid tissue will be collected. Blood will be collected again 3 months after surgery and middle ear and nasopharyngeal examinations will be performed. Exosomes will be isolated for follow-up studies as before surgery.

The primary outcome measures will be (1) ANOVA of the alterations and related gene expression of exosome contents in nasopharyngeal secretions in the four groups; (2) microbial alterations and the exosomes from biofilm on the surface of the adenoids in OA and CA groups preoperative and postoperative; and (3) the differences of exosomes from peripheral blood samples in OA and CA groups preoperative and postoperative.

Questions about this trial

What is this clinical trial studying?

An observational study of Otitis Media With Effusion and Adenoid Hypertrophy, run by Eye & ENT Hospital of Fudan University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

differential gene expression (time frame: 3 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jun 2022.
