The goal of this observational study consists of performing cluster analysis to decipher underlying disease mechanisms of type 1 diabetes in children and young adults. To this end, we will combine clinical, laboratory, genetic, transcriptomic, and metabolomic datasets of an extensively phenotyped cohort of children and young adults with type 1 diabetes. We will also assess the risk for cardiovascular diseases in this most vulnerable diabetes cohort.
Study Type
OBSERVATIONAL
Enrollment
150
100 extensively phenotyped pediatric and young adult patients for genotyping, metabolomic and lipidomic analyses. Polygenic risk scores for type 1 diabetes and cardiovascular disease will be performed. For patients older than 6 years who agree to do a second visit (optional), a Mixed Meal Tolerance Test (MMTT: the gold standard for assessing beta cell function) will be done as well as transcriptomic analysis.

RECRUITINGCluster analysis to decipher underlying mechanisms of type 1 diabetes
We will combine clinical, laboratory, genetic, transcriptomic, and metabolomic datasets of an extensively phenotyped cohort of type 1 diabetes patients (Children and young adults). We will create clinical and genetic correlates with the following clinical parameters: Age at diabetes onset (years), disease duration (years), BMI (kg/m2), diabetes autoantibodies, C-peptide level (pmol/l) and decline over time, HbA1c (%), insulin dose (U/kg/d), ketoacidosis at disease onset (y/n), lipid levels (Total cholesterol, triglycerides, HLD, LDL, Lipoprotein(a)), macro- and microvascular complications, ethnicity, family history for diabetes, associated autoimmune diseases (e.g., autoimmune thyroiditis or celiac disease) and mixed meal tolerance test.
