Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 35 to 75 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Chinese people

Who may be able to join

  • Aged 35-75 years.
  • Type A atrophic gastritis: Underwent gastroscopy in hospitals mentioned above. Gastroscopy and histopathology showed no significant atrophy of antrum mucosa, but significant atrophy of the body or fundus mucosa, accompanied by positive blood and/or gastric fluid anti-parietal cell antibodies and/or anti-internal factor antibodies. No obvious tumor, deep ulcer, severe bile reflux, severe erosion, or active bleeding. Type B atrophic gastritis: Underwent gastroscopy in hospitals mentioned above.

About this study

Official title: Clinical Characteristics, Lifestyle and Integrated Microbiome, Metabolome, Transcriptome, Genome Analysis in Autoimmune Gastritis

This research will be conducted nationwide in patients with autoimmune gastritis, focusing on their clinical characteristics, possible risk factors, and multi-omics analysis. Changes in gastrointestinal microbiota, host and microbial metabolism, gene transcription and biomarkers of autoimmune gastritis will be explored to provide evidence for further precise therapy of the disease.

Read the detailed description

Autoimmune gastritis is a chronic progressive disease that may develop into gastric cancer. However, on account of its low morbidity, atypical clinical and endoscopic manifestation, demanding technique for detection of serological markers, the diagnosis and treatment of this disease remains challenging. Therefore, there's inadequate studies focusing on its pathogenesis, metabolism, gene transcription, microbiota etc. In recent years, multi-omics analysis provides clinicians with depth and breadth understandings of diseases. This research, as well, aims at enhancing clinicians' knowledge of autoimmune gastritis to reduce the occurrence of neuroendocrine tumors, gastric cancer, pernicious anemia and other complications.

What is being measured

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

  1. Differences in microbiome

    Differences in microbiome within or between groups will be explored by metagenomic sequencing and validated by molecular biology experiments

    Measured: 1 year

  2. Differences in metabolome

    Differences in microbiome within or between groups will be explored by mass spectrometry and validated by molecular biology experiments

    Measured: 1 year

  3. Differences in transcriptome

    Differences in microbiome within or between groups will be explored by transciptome sequencing and validated by molecular biology experiments

    Measured: 1 year

  4. Differences in genome

    Differences in microbiome within or between groups will be explored by 16s RNA sequencing and validated by molecular biology experiments

    Measured: 1 year

Secondary outcomes (2)
  1. Differences in clinical outcomes

    Differences in clinical outcomes of Group 1, whether subjects have complications, such as folic acid or vitamin B12 deficiency (folic acid<3.1ug/L, vitamin B12<180pg/ml), anemia ( male Hb<130g/L, female Hb<115g/L), hyperplastic polyp, pseudopolyp, pyloric adenoma, type 1 neuroendocrine tumor or gastric cancer (pathologically confirmed), all these complications will be reported separately

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Autoimmune Gastritis, run by Shanghai Jiao Tong University School of Medicine 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 4 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 19 Apr 2023. 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 Jingyuan Fang, MD, Ph.D (+86-02153882450, fangjingyuan@sjtu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Differences in microbiome (time frame: 1 year). The study lists 4 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 19 Apr 2023.
