About this study

Official title: The Oral Microbiota in Autoimmune Thyroiditis is Distinctive And Predictive

Autoimmune thyroiditis (AITD) mainly includes Hashimoto's thyroiditis (HT) and Grave's disease (GD). Studies have shown that autoimmune thyroiditis is closely related to microbial disorders such as autoimmune thyroiditis However, there is no report on the relationship between oral microecology and autoimmune thyroiditis. Therefore, our group will study the correlation between oral microbiota and AITD.

Read the detailed description

Autoimmune thyroiditis (AITD) mainly includes Hashimoto's thyroiditis (HT) and Grave's disease (GD). Studies have shown that autoimmune thyroiditis is closely related to microbiological disorders. Intestinal microelements Both ecology and oral microecology belong to the category of microorganisms. It has been reported in the literature that intestinal microecology occurs disorder of autoimmune thyroiditis. However, there is no report on the correlation between oral microecology and autoimmune thyroiditis. When oral microbe flora When the immune system is disrupted, the immune balance is broken, the immune system is over-active, and the autoimmune disease (AID) is lost to the autoantigens and non-pathogenic commensal microbial flora antigens, including rheumatoid arthritis, Sjogren's syndrome, systemic lupus erythematosus, inflammatory bowel disease, and allergic diseases. However, the association between oral microbial flora and AITD remains unclear. . Therefore, the research group will carry out the correlation between oral microbial flora and AITD.

Questions about this trial

What is this clinical trial studying?

An observational study of Microbiota, run by First Affiliated Hospital of Harbin Medical University at 1 site in China.

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 3 inclusion and 11 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 27 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Contact Yunwei Wei (+86-0451-85553099, hydwyw11@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Transcriptional changes in oral microbiota (time frame: Baseline, 3 months, 6 months, 9 months, 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03447093, which also lists 3 linked publications.

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 27 Feb 2018.
