[Diabetology as an interdisciplinary challenge]

Type 2 diabetes mellitus is a growing chronic disease with a complex pathophysiology and multiple therapeutic options. Clinical prognosis is determined by multimorbidity and cardiovascular complications. For example, the prognosis of patients with diabetes hospitalized for heart failure is very poor with up to 50% mortality rate over the 3 years thereafter. Therefore, three levels have to be addressed in our approach to interdisciplinary diabetes care: screening and prevention, efficient patient-centered drug therapy, and a strategy for care including social environment of the patient suffering from complex diseases. Thus, we need diabetes specialists in out- and in-patient settings. Transsectoral interdisciplinary approaches to clinical care, as exemplary shown for the treatment of the diabetes foot syndrome, should be developed for other comorbidities, like renal and heart failure, respectively. The basis in the therapy of the cardiometabolic high-risk patient is prevention and multimodal treatment of cardiovascular risk factors. In this context, it is interesting to note that new cardiovascular outcome trials with a so-called safety design have shown that the GLP-1 receptor agonist liraglutide and the SGLT-2 inhibitor empagliflozin can reduce cardiovascular event rates. In addition, empagliflozin has significantly reduced the rate of hospitalization for heart failure. The latter has been included in the recent guidelines on heart failure by the European Society of Cardiology.
