Dyslipidemia in the metabolic syndrome and type 2 diabetes mellitus

Patients with type 2 diabetes mellitus or the metabolic syndrome have a unique dyslipidemia characterized, by hypertriglyceridemia; elevated blood levels of apolipoprotein B; small, dense low-density lipoprotein (LDL) cholesterol; and low levels of high-density lipoprotein (HDL) cholesterol, in particular HDL2-C. Treatment of the dyslipidemia associated with these disorders should focus on correcting the abnormal lipoprotein levels as well as LDL and HDL heterogeneity. Statins and fibrates are useful for treating elevated LDL in patients with and without diabetes or the metabolic syndrome. In addition, thiazolidinediones or niacin in combination with a statin show promise for correcting defects in LDL and HDL heterogeneity. The ultimate goal of treatment in this patient population is to prevent the development and progression of coronary artery disease. (C) 2003 by Excerpta Medica, Inc.
