About this study

Official title: Gut Microbiota is Associated With Autoimmune Thyroid Disease(GD and HT)

Autoimmune thyroid disease (AITD), which includes Hashimoto's thyroiditis (HT) and Grave's disease (GD), are the most common organ-specific autoimmune diseases and affect more women than men, with a female-to-male ratio from 5 to 10. Many studies have indicated that alterations in the gut microbiota are important environmental factors in the development of inflammatory and autoimmune diseases. Investigators systematically performed a comparative analysis of the gut microbiota in AITD patients and healthy controls.

Read the detailed description

Autoimmune thyroid disease (AITD), which includes Hashimoto's thyroiditis (HT) and Grave's disease (GD), are the most common organ-specific autoimmune diseases and affect more women than men, with a female-to-male ratio from 5 to 10. These two diseases are clinically diverse because in HT, T cells aid in the destruction of the thyroid epithelial cells (thyrocytes) and thyroid epithelial structure and eventual fibrous replacement of parenchymal tissue leading to hypothyroidism, whereas GD is primarily a humoral disease where auto-antibodies are generated against the thyroid stimulating hormone receptor (TSHR) leading to hyperthyroidism (2,163-165). However, these diseases still share several immunological features,and the disease may progress from one state to another as the autoimmune process evolves. Many studies have indicated that alterations in the gut microbiota are important environmental factors in the development of inflammatory and autoimmune diseases. Investigators systematically performed a comparative analysis of the gut microbiota in AITD patients and healthy controls.

What participants receive

  • Methimazole PillDrug

    Also called Methimazole

    Hyperthyroidism patients are treated with Methimazole Pill according to the guidelines

Hashimoto's thyroiditisHashimoto's thyroiditis (HT) is an organ-specific autoimmune disease in which both genetic predisposition and environmental factors serve as disease triggers.
healthy controlshealthy controls are all from normal volunteers
treatment_naive GDGD is primarily a humoral disease where autoantibodies are generated against the thyroid stimulating hormone receptor (TSHR) leading to hyperthyroidism.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 16S rRNAgene sequencing was used to measure the diversity of gut microbiota

    Intestinal microbes are different in different groups

    Measured: HC, treatment_naive HT and treatment_naive GD patients samples were collected at the enroll. Treated GD patients were collected until thyroid function resumed to the normal for at least 3 months of methimazole withdrawal

Secondary outcomes (1)
  1. Thyroid function tested by Chemiluminescence method

    Serum results are different in different groups and different time point

    Measured: Treatment_naive GD and treatment_naive HT patients thyroid function were tested at the enroll and after 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Gut 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 4 Jan 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 Wei Yunwei (+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?

16S rRNAgene sequencing was used to measure the diversity of gut microbiota (time frame: HC, treatment_naive HT and treatment_naive GD patients samples were collected at the enroll. Treated GD patients were collected until thyroid function resumed to the normal for at least 3 months of methimazole withdrawal). 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 4 Jan 2018.
