Overview
The aim of the prospective observational GDC-Study in patients with newly diagnosed diabetes mellitus aged 18-69 years at inclusion into the study is to characterize in detail the clinical, metabolical and immunological phenotype and monitor the progression of the disease and to compare the phenotype to glucose tolerant humans of similar age, body mass and sex distribution.
Detailed description
In detail, the following questions will be answered:
1. Are there different phenotypes with respect to insulin secretion, insulin sensitivity, micro- and macrovascular status and diabetic neuropathy at time of diagnosis? 2. Which factors modify the progression of the disease (Nutrition, subclinical inflammation, energy metabolism and physical activity)? 3. Can we identify subgroups at baseline with different progression of the disease? Patients are thoroughly examined at baseline and after 2, 5, and 10 years with annual telephone contacts in between.
Primary outcome measures
- Change of insulin sensitivity (M-Value) [Time frame: 2 and 5 years]
Secondary outcome measures (2)
- Change of insulin secretion [Time frame: 2 and 5 years]
- Incidence of any diabetic complication [Time frame: 2-10 years]
