Overview
Causes
Genetics
Type I hyperlipoproteinemia
- Genetic deficiency or dysfunction of enzyme lipoprotein lipase (LPL) or its cofactor, apo C-II.
Familial combined hyperlipidemia
- Autosomal dominant disorder
- Patients have either isolated triglyceride or LDL-c elevations or both.
- Family history of premature coronary artery disease in 1 or more first-degree relatives
- Family history for elevated triglycerides with or without elevated LDL-c levels.
Familial hypertriglyceridemia
- Autosomal dominant trait
- These patients and their families have isolated triglyceride elevations
- Increased risk of premature coronary artery disease.
- High carbohydrate or high glycemic diet
- Idiopathic (constitutional)
- Obesity
- Diabetes mellitus and insulin resistance - it is one of the defined components of metabolic syndrome (along with central obesity, hypertension, and hyperglycemia)
- Excess alcohol intake
- renal failure, Nephrotic syndrome
- Lipoprotein lipase deficiency - Deficiency of this water soluble enzyme, that hydrolyzes triglycerides in lipoproteins, leads to elevated levels of triglycerides in the blood.
- Lysosomal acid lipase deficiency or Cholesteryl ester storage disease
- Certain medications e.g. isotretinoin, estrogen, hydrochlorothiazide diuretics, beta blockers, protease inhibitors
- Hypothyroidism (underactive thyroid)
- Systemic Lupus Erythematosus
- Glycogen storage disease type 1.
