Blood Pressure Meds May Prevent Kidney Disease
ACE inhibitor blood pressure medications can reduce the risk of kidney disease in diabetes patients with high blood pressure, says a report in the Journal of the American Society of Nephrology.
Blood pressure medications known as angiotensin converting enzyme inhibitors, or ACE inhibitors, help to dilate blood vessels and lower blood pressure.
About 80 percent to 90 percent of people with type 2 diabetes also have high blood pressure, a major risk factor for kidney disease in persons with diabetes.
Typically, about 30 percent of persons with diabetes develop kidney failure, and an even larger percentage of them may be at risk of premature death from heart failure.
Controlling blood pressure in these patients may be critical in reducing or preventing the risk of kidney failure or death for these patients, says Dr. Piero Ruggenenti, of Mario Negri Institute for Pharmacological Research in Bergamo.
Dr. Ruggenenti’s study included more than 1,200 patients with type 2 diabetes and high blood pressure.
They were randomly assigned to receive either an ACE inhibitor medication; another type of blood pressure medication called a calcium channel blocker; a combination of ACE inhibitor and calcium channel blocker; or a placebo.
The researchers checked the study participants for rates of microalbuminuria - small amounts of the protein albumin in urine that are among the first signs of kidney disease.
After an average of three and one-half years, patients with good blood pressure control had lower rates of microalbuminuria, regardless of which treatment they received.
Patients who took the combination treatment showed the greatest decreases in blood pressure and were less likely to need additional medications to control their blood pressure.
ACE Inhibitors a Must Therapy
The researchers also found that taking an ACE inhibitor, either alone or as part of the combination treatment, provided further protection against kidney disease, even if a patient's blood pressure remained high.
"Treatment with an ACE inhibitor was particularly important when the blood pressure was poorly controlled - as may happen in most diabetic patients with hypertension, despite the use of two, three, or even more drugs," says Dr. Ruggenenti.
"Our results clearly show that an ACE inhibitor should always be used in patients with high blood pressure and diabetes, even when they have no evidence of renal [kidney] or cardiovascular disease," he says.

The following are the most common symptoms of kidney disease:
-

-
fatigue
-

nausea and/or vomiting
-
puffiness around eyes and/or swelling of hands and feet
-
skin may darken

The symptoms of a kidney disease may resemble other conditions or medical problems.
