Novel biomarkers for the early detection of Diabetic nephropathy
Staging
Surveillance
INTRODUCTION
The prevalence of type 2 diabetes mellitus (T2DM) is steadily increasing, mostly due to a combination of obesity, urbanization, and ageing population.
In parallel, the prevalence of its macrovascular and microvascular complications, such as diabetic nephropathy (DN), which occurs in 20 to 40% of type 2 diabetic patients, has risen.
Despite efforts made to slow the progression of DN, this is still the most common cause of end-stage renal disease (ESRD) in developed countries.

In the past, it was believed that DN only had one path of progression – from a normoalbuminuric stage, to microalbuminuria (UACR 30-300 mg/g), to end in overt proteinuria (UACR> 300 mg/g).
However, in the last few years a growing body of evidence has shown an accelerated decrease in glomerular filtration rate (GFR) predominately seen in type 2 diabetic chronic kidney disease (CKD) patients with UACR< 300mg/g.
This discovery has raised the possibility of their being two independent diabetic nephropathy phenotypes
