  • Title: Understanding and treating dyslipidemia associated with noninsulin-dependent diabetes mellitus and hypertension.

    Abstract:
    Hypertension and diabetes appear to increase coronary heart disease risk in part by causing an abnormality in lipid metabolism. Most affected are patients with familial dyslipidemic hypertension (FDH) and noninsulin-dependent diabetes mellitus (NIDDM). The lipid disorders most often encountered in these patients are increased levels of triglycerides, very low-density lipoprotein (VLDL) cholesterol, and small, dense low-density lipoprotein (LDL) cholesterol, and low levels of high-density lipoprotein (HDL) cholesterol. These abnormalities appear to result from increased hepatic secretion of VLDL particles due to increased concentrations of free fatty acids and glucose, reduced VLDL clearance due to reduced activity of lipoprotein lipase, and reduced LDL clearance due to glycosylation of ligand proteins. Treatment of the dyslipidemia associated with FDH should follow the guidelines from the National Cholesterol Education Program. Treatment in men and women with NIDDM should be considered when LDL cholesterol levels are 130 mg/dl or above, triglyceride levels are 200 mg/dl or above, or non-HDL cholesterol levels are 160 mg/dl or greater. Aggressive lifestyle changes should be initiated first, including weight loss in obese patients, control of glucose levels in those with NIDDM, avoidance of antihypertensive drugs that may worsen lipid levels in patients with FDH, and eating a diet restricting saturated fat and cholesterol. Addition of lipid-altering drugs should be considered if such changes do not achieve effective lipid control. The agent should be tailored to the patient's lipid profile, in general by using bile acid resins, niacin, or reductase inhibitors to lower LDL cholesterol and gemfibrozil or niacin to lower triglycerides. Niacin should be avoided in patients with NIDDM.
