Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to achieve more accurate early classification of diabetes and identification of which patients will rapidly require insulin treatment. The investigators will recruit 1200 participants who have been diagnosed with diabetes in the last year and were aged between 18 and 50 years at the time of diagnosis. The investigators will recruit an additional cohort of 800 participants diagnosed after age 50. The investigators will record clinical features and biomarkers that may help us to determine diabetes type at diagnosis and follow participants for 3 years to assess the development of severe insulin deficiency (measured using C-peptide) and insulin requirement. The investigators will assess utility of clinical features and additional biomarkers in identifying patients with rapid progression to insulin requirement. Findings will be integrated into a freely available clinical prediction models to assist classification of diabetes at diagnosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study is a prospective observational study which will assess the relationship between clinical features and biomarkers at diabetes diagnosis and type of diabetes defined by endogenous insulin secretion at 3 years diabetes duration.

The investigators will recruit a prospective cohort of 1200 adults that have been diagnosed with diabetes within the previous 1 year and aged between 18 and 50 at the time of diagnosis. The investigators will also recruit an additional cohort of 800 participants diagnosed with diabetes in the last year aged \>50 at diabetes diagnosis, who will be stratified by insulin treatment (insulin treated n=400).

On recruitment into the study, non-fasting (within 1-5 hours of a meal) blood sample will be collected for baseline analysis biomarker assessment (serum C-peptide, routine biochemistry, Islet autoantibodies (GAD, IA2, ZnT8)) and biobanking. Clinical features will be recorded, including weight, height, waist/hip ratio \& blood pressure. Participants will be asked to provide a home post-meal urine sample for Urinary C-Peptide Creatinine Ratio (UCPCR). At 1 year and 2 years post recruitment, participants will be contacted by telephone, email or in person to record concurrent treatment, hypoglycaemia and health service utilisation. Participants will be asked to collect a home post-meal urine sample for Urinary C-Peptide /Creatinine Ratio (UCPCR). HbA1c results will be obtained from participants GP practice or laboratory records.

At the end of the study, 3 years post recruitment, a non-fasting blood sample will be collected for serum C-peptide, routine biochemistry and stored for future biomarker analysis. Weight change, blood pressure, concurrent treatment, hypoglycaemia and health service utilisation data will be also be recorded.
