Nephropathy in NIDDM is associated with cellular markers for hypertension.
OBJECTIVE
To determine if nephropathy in NIDDM is associated with cellular markers for hypertension.


METHODS
We compared 11 patients with clinical diabetic nephropathy with 15 control subjects with no diabetic nephropathy. The patients were white and had had NIDDM for > or = 9 yr and serum creatinine levels < or = 177 M (2.0 mg/dl).


RESULTS
Patients with nephropathy were more obese and had higher blood pressures and triglyceride levels, and lower high-density lipoprotein cholesterol levels than control subjects. Erythrocyte sodium lithium countertransport activity, erythrocyte sodium content, and platelet sodium-proton exchange were higher in patients with nephropathy than in control subjects.


CONCLUSIONS
The results of this small study suggest that in white patients with long-standing NIDDM, diabetic nephropathy is associated with cellular markers for hypertension. Measurement of cellular markers for hypertension may be useful to identify patients who are at risk for developing nephropathy.
