Why does LPL deficiency cause pancreatitis?


Why does LPL deficiency cause pancreatitis?

Lipoprotein lipase deficiency is a genetic disorder in which a person has a defective gene for lipoprotein lipase, which leads to very high triglycerides, which in turn causes stomach pain and deposits of fat under the skin, and which can lead to problems with the pancreas and liver, which in turn can lead to diabetes.

What does the LPL gene do?

The LPL gene provides instructions for making an enzyme called lipoprotein lipase. This enzyme is found primarily on the surface of cells that line tiny blood vessels (capillaries) within muscles and in fatty (adipose) tissue.

What is LPL activated by?

LPL is produced in fat, skeletal, and heart muscle. Activated by its cofactor apoC-II [198], LPL mediates the hydrolysis of TG in CM and VLDL at the luminal side of the endothelium. Generated FFA are subsequently used for energy production in muscle or stored as fat in adipose.

What is LPL deficiency?

Summary. Familial lipoprotein lipase (LPL) deficiency is a rare genetic metabolic disorder characterized by a deficiency of the enzyme lipoprotein lipase.

Why is LP A atherogenic?

On an equimolar basis, Lp(a) is considered more atherogenic than LDL due to the presence of phosphocholine containing oxidized phospholipids (OxPLs) bound to apo(a). OxPLs are recognized as endogenous danger-associated molecular patterns.

What complications would appear in the absence of LPL?

Symptoms may include any of the following:

  • Abdominal pain (may appear as colic in infants)
  • Loss of appetite.
  • Nausea, vomiting.
  • Pain in the muscles and bones.
  • Enlarged liver and spleen.
  • Failure to thrive in infants.
  • Fatty deposits in the skin (xanthomas)
  • High triglyceride levels in the blood.

Is low lipase bad?

Low levels of lipase can mean that your pancreas is not functioning well and is struggling to produce digestive enzymes. Some conditions that can increase lipase can sometimes also decrease this enzyme.

Why is lipoprotein A bad?

Lp(a) is a type of low-density lipoprotein (LDL). LDL is known as “bad” cholesterol. High levels of Lp(a) can create plaque in your blood vessels. This is a buildup of cholesterol that lessens blood flow through your arteries.

How do you treat high Lp A?

The best treatment for LP(a) is to reduce the cholesterol burden of the particle with a statin which will shrink the particle size. A new injectable treatment known as an anti-sense therapy which stops LP(a) being made is currently due to start phase 3 clinical research trials.

Where is the LPL gene located in the body?

Collapse Section The LPL gene provides instructions for making an enzyme called lipoprotein lipase. This enzyme is found primarily on the surface of cells that line tiny blood vessels (capillaries) within muscles and in fatty (adipose) tissue.

How is lipoprotein lipase deficiency ( LPL ) treated?

Treatment A proportion of LPL deficient individuals can be successfully treated by dietary restriction of fats, but many are still plagued by recurrent abdominal pain and episodes of acute pancreatitis. The goal of restricting fat intake is to reduce chylomicronemia and hypertriglyceridemia enough to prevent symptoms.

How does heparin test for lipoprotein lipase deficiency?

Clinical Testing and Workup. Blood tests can reveal reduced activity of the lipoprotein lipase enzyme in the plasma, following intravenous administration of heparin. Heparin is a substance normally found in the liver that stimulates the release of lipoprotein lipase in the body.

How does lipoprotein lipase break down triglycerides?

Lipoprotein lipase (LPL) represents an important enzyme in the human body that metabolizes triglycerides. This enzyme breaks down molecules that transport fat from the intestines to the bloodstream, where the fat is converted into energy or stored.
