Lipoprotein Disorders

Lipoprotein disorders are detected by measuring lipids in serum after a 10-hour fast.

LIPOPROTEIN DISORDERS

Lipoprotein disorders are detected by measuring lipids in serum after a 10-hour fast. Risk of heart disease increases with concentra-tions of the atherogenic lipoproteins, is inversely related to levels of HDL, and is modified by other risk factors (Table 35–1). Evidence from clinical trials suggests that LDL cholesterol levels of 60 mg/dL may be optimal for patients with coronary disease. Ideally, triglycerides should be below 120 mg/dL. Although LDL-C is still the primary target of treatment, reducing the levels of VLDL and IDL is also important. Calculation of non-HDL cholesterol provides a means of assessing levels of all the lipoproteins in the VLDL to LDL cascade. 


Differentiation of the disorders requires identification of the lipoproteins involved (Table 35–2). Diagnosis of a primary disorder usually requires further clinical and genetic data as well as ruling out secondary hyperlipidemias (Table 35–3).


Phenotypes of abnormal lipoprotein distribution are described in this section. Drugs mentioned for use in these conditions are described in the following section on basic and clinical pharmacology.
