Overview
Diabetic kidney disease (Diabetic Nephropathy) is the most common cause of chronic kidney disease and end stage renal disease (ESRD) in the United States [1] . Due to the ongoing world wide increase in the incidence of Diabetes Mellitus, Diabetic Nephropathy (DN) is increasingly a major cause of ESRD disease world wide [2].
Diabetic Nephropathy affects male and female patients equally. The incidence of DN in African-Americans (blacks), Native Americans and people of Mexican origins is greater than in white Americans [3]. Currently, the main goal in the treatment of diabetic nephropathy is to slow the progression of chronic kidney disease. This is achieved by excellent control of hyperglycemia, dyslipidemia, and blood pressure. Antiproteinuric therapy through Renin-Angiotensin-Aldosterone System Inhibitors is considered to be a major pillar of the treatment [4]. Renin-Angiotensin-Aldosterone System inhibition it thought to be beneficial in the early stages of diabetic nephropathy through decreasing proteinuria and progression [5]. Therefore, early diagnosis and institution of prompt treatment is very important in the management of Diabetes Nephropathy. Also, the role of diabetes prevention becomes paramount patients at high risk (e.g. metabolic syndrome, impaired glucose tolerance).
Diabetic nephropathy (DN) is characterized by the presence of proteinuria or decreased renal function in patients with diabetes mellitus.[6][7][8] However, diabetic nephropathy can also present in form of non-proteinuric decline in GFR, and although proteinuria remains the hallmark of diagnosis for diabetic nephropathy, there are emerging trends suggestive of non proteinuric diabetic nephropathy [9].
Early Diabetic Nephropathy
The range of proteinuria in early DN is shown below[6][7][8]:
- 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[6][7][8]:
- Proteinuria > 500 mg/24 hrs or albuminuria > 300 mg/24 hrs.
- Estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73m2
Historical Perspective
Classification
Pathophysiology
Diabetic nephropathy is a serious complication in patients with long standing Type 1 or Type 2 Diabetes Mellitus. It usually occurs in about 10 to 15years following the onset of diabetes mellitus. Poor glycemic control, dyslipidemia, smoking, and environmental and genetic factors play important roles in the development of diabetic nephropathy.

Laboratory Findings
Microalbuminuria, as defined by an urinary albumin-to-creatinine ratio of >30mg/g is an early diagnostic clue to diabetic nephropathy. Some patients may go on to develop high-grade nephrotic range proteinuria, while others may develop diabetic nephropathy without any measurable albuminuria.
