Trial summary

Diabetes mellitus is a common chronic disease with a huge socioeconomic burden worldwide. Type 1 Diabetes(T1D) accounts for nearly 95% of diabetes in pediatric age and a lifelong dependence on exogenous insulin. Read more about this study

Key requirements

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 Up to 18 years
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult

Study population: Children and adolescents under follow-up at Coimbra Pediatric Hospital - Coimbra University and Hospital Centre (CHUC), either in specific clinic (Diabetes - for T1D group) or that have been observed at a general endocrine or pediatrics clinics for a suspition of disease that was not confirmed (for control group). For the genetic related group, children and adolescents were recruited within T1D families and were observed in a single time point, at the time of their brother/sister.

Who may be able to join

  • T1D Group: children diagnosed with T1D, according to internationally defined criteria, with at least one positive pancreatic antibody and under functional insulin.
  • Genetic-related group: children without T1D, age- and sex-matched with T1D group, recruited among T1D relatives;
  • Control group: children without T1D, age- and sex-matched with T1D group, recruited from general endocrinology clinics, among children without disease or genetic relation with T1D children;

Who cannot join

  • Obesity, according to WHO standards for pediatrics;
  • Hypertension, as ≥95th percentile according to International Consensus;
  • Other auto-immune diseases;
  • Diabetes in the context of syndromic features/secondary to treatments;
  • Hypothyroidism, adrenal insufficiency or hypercortisolism;
  • Children under somatotropin/oncologic treatment;
  • Under medications affecting glucose metabolism

About this study

Diabetes mellitus is a common chronic disease with a huge socioeconomic burden worldwide. Type 1 Diabetes(T1D) accounts for nearly 95% of diabetes in pediatric age and a lifelong dependence on exogenous insulin. Its diagnosis is based on symptoms and/or autoantibodies, both identified too late to avoid the disease progress. Ideally, children should be screened whilst assymptomatic, when there is endogenous insulin production, but C-peptide and beta-cell function are starting to decline. Early diagnosis would allow interventions capable of preventing disease progress and/or to preserve beta-cell function, ultimately delaying/avoiding insulin dependence. Given their association with pathogenesis of diabetes, Extracellular Vesicles have emerged as potential biomarkers for diagnosis and progression of diabetes. This project proposes the development of a non-invasive biomarker of preclinical T1D, based on miRNA characterization in urine, allowing a timely identification of children that can benefit from preventive therapies and, in the future, to cure T1D.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Blood and urine samples collectionDiagnostic test

    Blood and urine were collected at a single time point for all participants, from the tree study groups. Fasting for blood collection and the first urine in the morning were required.

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetes Mellitus, Type 1 and Diabetes Mellitus, run by Unidade Local de Saúde de Coimbra, EPE at 1 site in Portugal.

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 7 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: under way, not looking for participants, as of the sponsor's last update on 18 Feb 2025. 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 Portugal. 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?

This study is still under way. Results are not available in the source record yet.

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?

Urine miRNAs extracellular vesicles molecular signatures for the study groups (time frame: October/23 until July/2024). The study lists 2 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 18 Feb 2025.
