Insights

Pregnancy in women with homozygous familial hypercholesterolemia (HoFH) poses significant risks. However, with careful management, including LDL-apheresis, patients without cardiovascular disease may have a favorable prognosis.

Area of Science:

  • Cardiovascular Medicine
  • Genetics
  • Metabolic Disorders

Background:

  • Familial hypercholesterolemia (FH) is an inherited disorder causing lifelong high LDL-C levels and premature atherosclerosis.
  • Pregnancy exacerbates risks for FH patients due to physiological changes and limited treatment options.
  • Extracorporeal LDL-apheresis is a potential therapeutic strategy for managing FH during pregnancy.

Purpose of the Study:

  • To evaluate the risks and outcomes of pregnancy in women with homozygous familial hypercholesterolemia (HoFH).
  • To assess the role of LDL-apheresis in managing HoFH pregnancies.

Main Methods:

  • Case report series of six HoFH women detailing 13 pregnancies.
  • Analysis of pregnancy outcomes including successful births, abortions, and interruptions.
  • Inclusion of cases treated with LDL-apheresis.

Main Results:

  • Pregnancy in HoFH women carries substantial risks, including one lethal complication.
  • Nine pregnancies resulted in successful outcomes.
  • Two successful pregnancies were managed with LDL-apheresis.

Conclusions:

  • HoFH pregnancies present significant risks but can have good outcomes for patients without cardiovascular decompensation.
  • LDL-apheresis is a crucial intervention for managing HoFH during pregnancy.

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Lipid-derived Compounds in the Human Body

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various  biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Lipid Absorption01:24

Lipid Absorption

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
