[New aspects of pharmacological nephroprotection].

Current estimates forecast that chronic kidney diseases will be the fifth most common cause of death worldwide by 2040. The prevalence of chronic renal diseases increases with age and, in many countries, affects patients with overweight, diabetes and hypertension. The primary objective of the treatment of chronic renal diseases is the delay of disease progression. Established markers for the deterioration of renal function include glomerular filtration rate and albuminuria. Pharmacological blockade of the renin-angiotensin-aldosterone system (RAAS) by angiotensin-converting enzyme inhibitors (ACE) or angiotensin receptor blockers (ARB) represents the cornerstone of drug-related nephroprotection. Current Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommend the use of ACEI or ARB for diabetic and non-diabetic patients with moderate and heavy albuminuria. In recent years, sodium-glucose linked transporter 2 inhibitors (SGLT-2 ) have been established in the field of cardio- and nephroprotection. Their protective effects occur regardless of blood sugar reduction. Current data suggest that the use of SGLT‑2 inhibitors will soon be part of therapy in non-diabetic kidney disease. One of the first drugs in this substance class, dapagliflozin, is already approved in Germany for the treatment of chronic renal diseases in adults with and without type 2 diabetes.
