Multicenter Studies
The DZD has set up multicenter clinical studies to develop precision prevention and therapy measures, i.e. the right treatment for the right patient group at the right time (Precision Medicine). Topics include type 1 diabetes and type 2 diabetes, gestational diabetes, secondary diseases, treatment of fatty liver in diabetes and insulin resistance in the brain. The Germany-wide cooperation in the research network makes it possible to initiate such large-scale studies and recruit the necessary participants. In total, more than 5,000 test subjects have already participated in the studies, which are being conducted at up to ten study locations.
First results are already available. Studies have shown that there are different subtypes of prediabetes and diabetes. Not every subgroup has the same risk of developing diabetes or severe secondary diseases. In new studies, the DZD is now developing interventions and therapies tailored to the individual subgroups to prevent or at least delay the onset of the metabolic disease and its complications.

DZD Core Data Set
 |
The partners in the German Center for Diabetes Research (DZD) have agreed on a common DZD Core Data Set (DZD CDS) for clinical parameters, which is based on international IT and terminology standards. This is a central requirement for comprehensive joint data collection and use.
The DZD Core Data Set consists of 8 modules and a total of 126 parameters that are defined interdisciplinary. There are also optional parameters that are subject-specific and can be included in data analyses depending on the research question.
The DZD basic dataset establishes definitions for the collection of diabetes-relevant clinical parameters and thus makes a valuable contribution to diabetes research and forms the basis for future progress in the treatment and prevention of this widespread disease.
FAIR criteria and update: The DZD Core Data Set was revised in 2022 according to the FAIR criteria. These criteria emphasize the importance of data that is findable, accessible, interoperable and reusable. The update ensures that the dataset meets the highest standards and fulfills current research requirements.
In 2024, the Core Data Set of the German Centers for Health Research (DZG) was integrated into the DZD Core Data Set. Basic clinical parameters are thus recorded in all DZGs according to a definition, regardless of indication.
The focus of the DZD CDS is on: prediabetes, type 1 and type 2 diabetes, adults, metabolic issues, pathophysiology of metabolism

Test Triangle Study
The "Test-Triangle" study examines whether the use of the "Triangle" smartphone app helps women after having had gestational diabetes to better integrate a healthy lifestyle into their daily lives.
The study is aimed at women who have been diagnosed with gestational diabetes during a recent pregnancy. This metabolic disorder is associated with an increased risk of developing type 2 diabetes later on. However, the right lifestyle can significantly reduce this risk. Unfortunately, young mothers have little time for their own health. For this reason, the "Triangle" smartphone app was specifically developed for this group. The app provides support to help lead a healthy lifestyle in the areas of exercise, nutrition and stress reduction. Users of the app are mentored by a qualified online coach who takes their individual needs into account and who adapts the content of the app accordingly. With the help of the app, more healthy habits can be incorporated into the everyday life of the participants step-by-step over a period of 6 months.
Recruitment for this study has been completed.

Prediabetes Lifestyle Intervention Study (PLIS, FollowUp)
Conventional lifestyle intervention is not sufficient to prevent type 2 diabetes in all people with prediabetes. Only individually tailored prevention can be effective here. In the completed multicenter Prediabetes Lifestyle Intervention Study (PLIS), the DZD set itself the goal of developing such personalized preventive measures. After extensive phenotyping, the PLIS study participants underwent different lifestyle programs with nutritional counseling and supervised physical activity. 1,145 patients were recruited for the PLIS study. To scientifically follow up this valuable cohort, the follow-up of the study participants was extended to a long-term observation over a period of 12 years after the intervention. Cluster analyses of the PLIS study identified first subtypes of prediabetes that have a particularly high risk of secondary diseases.
Recruitment for the study is now completed.
DZD Prediabetes Cohort
Prediabetes is the precursor stage of diabetes in which the blood glucose levels are already abnormal. In order to develop personalized prevention strategies for type 2 diabetes, the DZD, based on previous studies, formed a unique prediabetes cohort that is unique in Germany with 8,106 participants who are continuously being investigated. In these patients, the blood glucose concentrations of the oral glucose tolerance test were abnormal at the time of enrollment in the study, but no diabetes was present. The current data analysis showed that a family history of diabetes can already increase the risk of prediabetes by 40 percent. The participants will be monitored in follow-up studies.
EMLIFA Study
The study has shown that the diabetes drug empagliflozin, an SGLT-2 inhibitor, can significantly reduce liver fat levels in patients. The study has been completed.
