According to statistics diabetes mellitus is considered to be the leading cause for end stage renal disease in Germany, approximately 35% of the patients starting on dialysis are affected by diabetes-induced nephropathy. This can be seen in countries all over the world. This situation has been known for years. To date, neither structured intervention methods nor educational programs have been designed for and targeting those affected, which would consequently allow for structured, multifactorial intervention at an early stage of diabetic nephropathy. Multifactorial interventions, as published in the Steno-2 trial, appear to be highly effective with regard to long-term complications of diabetes. In order to realize this approach for the affected as well as the medical staff caring for patients with diabetes-induced nephropathy we developed DiaNe®, a consultation and support program, which is designed to give detailed information to the affected in order to induce behavioral changes. We were able to show a clinically significant reduction of microalbuminuria within a first monocenter evaluation trial. We wanted to verify this effect by means of a prospective multicenter randomized cohort trial according to GCP-ICH guidelines.
