[Diagnosis and management of diabetic nephropathy]

Diabetic nephropathy(DN) is the most common cause of chronic kidney disease, leading to end-stage renal disease (ESRD) and cardiovascular disease (CVD). The overall number of patients with DN will continue to increase in parallel with the increasing global pandemic of type 2 diabetes. The detection of albuminuria is most important for diagnosis of early stage of DN, and also estimated glomerular filtration rate (eGFR) should be assessed, because both albuminuria and reduction of GFR are recognized as the independent risk factor for progression of ESRD and initiation of CVD, respectively. Based on landmark clinical trials, both DN and CVD have become preventable by controlling conventional factors, including hyperglycemia targeting HbA1c<7.0%, hypertenstion using renin angiotensin system inhibitors, dyslipidemia using statins or fibrates, and multifactorial treatment.
