Our research work has three main lines 1. To study the heterogeneity of childhood diabetes (focus on the link between type 1 & type 2 diabetes) with the overall aims to increase the knowledge of the pathogenesis behind the disease (dissect the heterogeneisis) and improving classification towards individualized medicine. 2. We focus on the risk to develop celiac disease after the onset of diabetes in the Type 1 Diabetes childhood population. We try to find the predictive factors important for the increased risk to develop both diseases. We will also use this data to develop a safe and cost effective screening tool finding children at risk for celiac disease. 3. The Diabglut study, where the aim of this project is to investigate whether a gluten free diet after the onset of type 1 diabetes (T1D) can better preserve the remaining beta cell mass and study if a year gluten free diet may at the same time prevent the development of Celiac Disease (CD) in these patients.
