Blood pressure disturbance in diabetes mellitus.
BACKGROUND
Arterial hypertension and, less often, postural hypotension are frequently associated with diabetes mellitus, and with diabetic complications and death.


OBJECTIVE
To review data on the relationship between hypertension and nephropathy in diabetes mellitus.


METHODS
We reviewed data on both retinopathy and nephropathy in hypertensive diabetic patients. Data suggesting that vasopressin levels might affect blood pressure in upright patients with postural hypotension due to cardiocirculatory diabetic neuropathy were also examined. Antihypertensive treatment during different phases of diabetic nephropathy in insulin-dependent diabetes was reviewed.


RESULTS
The data showed that hydrochlorothiazide and nitrendipine reduce urinary protein excretion in parallel with a reduction in blood pressure. However, the decreases in urinary protein excretion induced by captopril are not correlated with a reduction in blood pressure and may be related to decreases in intraglomerular pressure found in patients with mild renal failure taking furosemide. Domperidone, a peripherally acting dopaminergic antagonist is an additional therapeutic option for the treatment of diabetic postural hypotension.
