Chylomicronemia syndrome is a disorder passed down through families in which the body does not break down fats (lipids) correctly. This causes fat particles called chylomicrons to build up in the blood.
Chylomicronemia syndrome is a rare genetic disorder. It occurs when a protein (enzyme) called lipoprotein lipase (LpL) is broken or missing. LpL is normally found in fat and muscle and helps break down certain lipids. When LpL is missing or broken, fat particles called chylomicrons build up in the blood. This build up is called chylomicronemia.
Symptoms may start in infancy and include:
Examination and tests may show an enlarged liver and spleen, inflammation of the pancreas, fatty deposits under the skin, and possibly deposits in the retina of the eye.
A creamy layer due to chylomicrons in the blood will appear when blood spins in a laboratory machine.
The triglyceride level is extremely high.
A completely fat-free diet is required.
Symptoms tend to be dramatically reduced when patients adhere to a fat-free diet.
When untreated, the excess chylomicrons may lead to bouts of pancreatitis, which can be extremely painful and even life threatening. There seems to be no increased risk for atherosclerotic heart disease.
Seek immediate medical care if you have abdominal pain or other warning signs of pancreatitis.
Call for an appointment with your health care provider if you have a personal or family history of high triglyceride levels.
There is no way to prevent this syndrome, but sticking to a fat-free diet and avoiding alcohol can prevent its symptoms.
