Monitoring glomerular function in diabetic nephropathy. A prospective study

Area of Science:

• Nephrology
• Endocrinology
• Diabetology

Background:

• Diabetic nephropathy is a major complication of insulin-dependent diabetes.
• Monitoring glomerular function is crucial for managing diabetic nephropathy progression.

Purpose of the Study:

• To prospectively monitor glomerular function in patients with diabetic nephropathy.
• To evaluate the sensitivity of different markers for assessing renal function decline.

Main Methods:

• Prospective monitoring of 13 patients with insulin-dependent diabetes and nephropathy.
• Measurement of glomerular filtration rate (GFR) using 51Cr-EDTA clearance.
• Assessment of plasma creatinine and beta 2-microglobulin levels.

Main Results:

• A linear decline in GFR was observed in all patients.
• Plasma creatinine was insensitive for early detection of nephropathy.
• Inverse beta 2-microglobulin showed a highly significant correlation with GFR, indicating its sensitivity for early impairment.

Conclusions:

• Beta 2-microglobulin is a sensitive marker for early detection of renal function impairment in diabetic nephropathy.
• GFR decline is not directly related to age, diabetes duration, or blood glucose control.
• Therapeutic interventions can be evaluated by precise GFR decline and protein clearance measures.
