Membranoproliferative glomerulonephritis complicating diabetic nephropathy.
BACKGROUND
Renal diseases other than diabetic nephropathy can be found in diabetic patients who have undergone renal biopsy. Various forms of primary and secondary glomerular diseases were reported, but membranoproliferative glomerulonephritis was rare.


METHODS
Analyzing data at our Department for the past three years, we noted 18 patients with primary membranoproliferative glomerulonephritis and 4 associated with diabetic nephropathy.


RESULTS
Nodular glomerulosclerosis with diffuse membranoproliferative glomerulonephritis was registered in two patients and a diffuse form of diabetic nephropathy with a combination of segmental and diffuse changes characteristic of membranoproliferative glomerulonephritis in the other two patients.


CONCLUSIONS
Analyzing what can be common for these two diseases we can conclude that they are at least three disorders: 1. hyperperfusion injury, hallmark for the diabetic nephropathy, but also with the highest incidence in membranoproliferative glomerulonephritis than in the other glomerulonephritides; 2. mesangial matrix expansion, and; 3. thickening of all extracellular membranes.
