Lipoprotein distribution in the metabolic syndrome, type 2 diabetes mellitus, and familial combined hyperlipidemia

Metabolic abnormalities associated with the metabolic syndrome are also present in patients with type 2 diabetes mellitus and in those with familial combined hyperlipidemia (FCHL). These abnormalities include central obesity, insulin resistance with hyperinsulinemia, hypertension, increased plasma triglycerides, and decreased high-density lipoprotein cholesterol levels. Other characteristics associated with FCHL include the presence of small, dense low-density lipoprotein cholesterol and increased apolipoprotein B. Patients with these abnormalities are at an increased risk for premature coronary artery disease. Treatment of the dyslipidemia associated with type 2 diabetes and FCHL with a combination of a statin and a thiazolidinedione or niacin offers the most comprehensive modality to correct the various lipid abnormalities.
