About this study

Official title: A Prospective Cohort Study of Clinical Characteristics and Genetic Susceptibility of Type 1 Diabetes in Chinese Adolescents and Youth

primary outcome: To explore the genetic susceptibility of diabetes in Chinese adolescent and youth.

secondary outcomes:

  1. To classify diabetes by gene detection in Chinese adolescent and youth.
  2. To make the relationship between genotype and clinic phenotype in type 1 diabetes.
  3. To evaluate the effect of environmental factors (intestinal ecosystem)in the pathogenesis of diabetes.
Read the detailed description

Phase 1: Baseline investigation Aims: To explore genetic susceptibility of diabetes in Chinese adolescent and youth.

Subjects and Methods: 500 patients under diabetic conditions and sex,age-matched NGR Healthy control(2:1) will be enrolled ,all aged from 14-30 years old. A comprehensive examination including questionnaire, anthropometric measurements, biochemical analysis will be performed in each study participant. Diabetes should be diagnosed according to the WHO 1999 criteria,type 1 or type 2 diabetes diagnosed by clinical features recommended by International Society of Pediatric and Adolescent Diabetes ( ISPAD ).

Phase 2: Cohort follow-up Aims : To explore the association of genetic backgrounds and clinical characteristics in different types of diabetes in Chinese adolescent and youth.

Subjects and Methods: To recruit and follow up 200 newly diagnosed and genotyped patients for 3 years. Questionnaire, anthropometric measurements, biochemical analysis performed respectively at baseline,3,6,12,24,36 months after enrollment.

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetes Mellitus, 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 5 inclusion and 3 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 13 Nov 2013. 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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Deterioration of pancreatic islet function (time frame: 3 years). 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 NCT01938365, which also lists 1 linked publication.

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 13 Nov 2013.
