Using Pharmacogenetics to Improve Treatment in Early-onset Diabetes (UNITED)
|Study Design:||Time Perspective: Cross-Sectional|
|Official Title:||Using Pharmacogenetics to Improve Treatment in Early-onset Diabetes|
- Identification of patients with monogenic diabetes [ Time Frame: Within 4 years from start of project ] [ Designated as safety issue: No ]The aim of this project is to identify the prevalence of patients with monogenic diabetes resulting from mutations in the HNF1A/HNF4A/GCK genes, amongst patients with early-onset diabetes, diagnosed less than 30 years.
- To examine the impact of making a diagnosis of monogenic diabetes on patients' treatment, glucose control and quality of life. [ Time Frame: Within 4 years of the project start date. ] [ Designated as safety issue: No ]
To measure the impact of making a molecular genetic diagnosis of monogenic diabetes by examining at baseline, 1 month, 6 months and 12 months the following parameters:
i) treatment - both type and dose; ii) glucose control - measured by HbA1c at 3, 6 and 12 months post-treatment change; iii) quality of life - by appropriate protocols.
- To develop a health economic model of the care pathway leading to testing of monogenic diabetes. [ Time Frame: Within 4 years of the project start date. ] [ Designated as safety issue: No ]To develop a health economic model that can measure the success, cost and potential economic benefit of using the care pathway to identify patients with monogenic diabetes and potentially change their treatment. This will allow assessment of when testing is appropriate on health economic grounds.

Diabetes diagnosed under 30 years
Patients currently under 50 years of age diagnosed with diabetes under 30 years.
Other: patient care pathway
Stage 1: Urinary c-peptide creatinine ratio (UCPCR); if positive progress to Stage 2.
Stage 2: Pancreatic auto-antibodies measurement (GAD65 & IA2); if negative progress to genetic testing.
Genetic testing for HNF1A, HNF4A, GCK. If positive, progress to Stage 3.
Stage 3: review and potential change of diabetes treatment. Monitor success via use of three standardised health and quality of life questionnaires and Hba1c pre-treatment change and at 1, 3, 6 and 12 months post-treatment change.
