Overview
Diabetic nephropathy (DN) is characterized by the presence of proteinuria or decreased renal function in patients with diabetes mellitus.[1][2][3]
Early Diabetic Nephropathy
The range of proteinuria in early DN is shown below[1][2][3]:
- Males: Microalbuminuria in the range of 30-300 mg/24 hrs or a spot urinary albumin/creatinine ratio of 30-300 mg/g
- Females: Microalbuminuria in the range of 30-300 mg/24 hrs or a spot urinary albumin/creatinine ratio of 20-200 mg/g
Overt Diabetic Nephropathy
Overt DN is defined according to the presence of proteinuria or according to renal function. The following ranges in overt DN are shown below[1][2][3]:
- Proteinuria > 500 mg/24 hrs or albuminuria > 300 mg/24 hrs.
- Estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73m2
