    General Discussion

    Cholesteryl ester storage disease (CESD) is a rare genetic disorder characterized by subtotal defect of an enzyme known as lysosomal acid lipase (LIPA or LAL). This enzyme is essential for hydrolysis of triglycerides and cholesteryl esters in lysosomes. CESD is caused by mutations in the lysosomal acid lipase (LIPA) gene. The disorder is inherited as an autosomal recessive trait. Deficiency of the LIPA enzyme causes lipids storage in tissues and organs of the body potentially causing a variety of symptoms. In the liver the consequences are hepatomegaly due to hepatic steatosis and fibrosis that can lead to micronodular cirrhosis. Some individuals may not be diagnosed with CESD until adulthood.

    While mutations causing Wolman disease produce an enzyme with no residual activity or no enzyme at all, CESD-causing mutations encode for LAL which retains some enzyme activity Genetic and biochemical evidence that CESD and Wolman disease are distinguished by residual lysosomal acid lipase activity. CESD belongs to a group of diseases known as lysosomal storage disorders. Lysosomes are particles bound in membranes within cells that break down certain fats and carbohydrates. Defective lysosomal enzymes associated with CESD leads to the accumulation of certain fatty substances (mucolipids) and certain complex carbohydrates (mucopolysaccharides) within the cells of many tissues of the body.

    Congratulations! Your total cholesterol level is in the Desirable range, and your level of "bad" LDL cholesterol is optimal.

    Congratulations! Your total cholesterol level is in the Desirable range, and your level of "bad" LDL cholesterol is near optimal.

    Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is borderline high. If your LDL goes higher, your total cholesterol level could become Borderline High. Consider reducing the amount of foods you eat with saturated fats and increasing physical activity. If you get more exercise, your level of "good" HDL cholesterol may increase, which could also help to keep your levels of LDL and total cholesterol in check.

    Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is High. This may mean that your level of high-density lipoprotein (HDL), or "good" cholesterol, is too low. It is best to have a high level of "good" HDL and a low level of "bad" LDL. The HDL helps keep your LDL level in check. Ask your doctor for your HDL level. If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level.

    Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is Very High. This may mean that your level of high-density lipoprotein (HDL), or "good" cholesterol, is too low. It is best to have a high level of "good" HDL and a low level of "bad" LDL because the HDL helps keep your LDL level in check. Ask your doctor for your HDL level. If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level.

    Your total cholesterol level is Borderline High, but fortunately your level of "bad" LDL cholesterol is optimal. This could mean you have a high level of high-density lipoprotein, or "good" HDL cholesterol, which protects against heart disease. Or you could have other non-measured increases in LDL-like particles that can increase heart disease. Your LDL level also could be optimal if you are taking a statin medication. Please check with your doctor to get your complete lipid profile and see if you may need additional treatment. In the meantime, find more information on WebMD's Cholesterol Health Center.
