Summary
Familial hypercholesterolemia (FH) management in children can target the gut. Inhibiting intestinal cholesterol absorption with ezetimibe and other strategies offers effective LDL-C reduction, especially when statins are not ideal.
Area of Science:
- Cardiovascular Medicine
- Gastroenterology
- Genetics
Background:
- Familial hypercholesterolemia (FH) is a genetic disorder causing high childhood LDL-C, increasing cardiovascular disease risk.
- While liver receptors are key, the gastrointestinal tract is crucial for cholesterol homeostasis and a therapeutic target.
Purpose of the Study:
- To review intestinal cholesterol absorption mechanisms in pediatric FH.
- To examine pharmacological and dietary interventions modulating these pathways.
Main Methods:
- Review of clinical and experimental evidence on intestinal cholesterol absorption.
- Analysis of therapies targeting NPC1L1, bile acid reabsorption, and cholesterol efflux.
Main Results:
- Intestinal cholesterol absorption inhibition is effective for pediatric FH, particularly with ezetimibe (NPC1L1 inhibitor).
- Combination therapy (ezetimibe/statins) shows greater LDL-C reduction.
- Dietary interventions and bile acid sequestrants offer additional benefits.
Conclusions:
- Understanding gut cholesterol metabolism is vital for pediatric FH treatment.
- Emerging therapies like microbiota-targeting strategies hold future promise.
- Personalized approaches are key for effective FH management in children.

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

01:24Lipid Absorption
752
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...

01:06Carrier-Mediated Transport
549
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

01:20Factors Affecting Dissolution: Drug Permeability, Stability and Stereochemistry
267
Orally administered drugs primarily enter the systemic circulation via passive diffusion through the intestinal membranes. The drug's absorption is influenced by drug stability in the gastrointestinal GI tract, membrane permeability, the surface area available for absorption, luminal drug concentration, and residence time in the lumen. Drug permeability can be enhanced by adjusting the lipophilicity, polarity, or molecular size of the drug, promoting its passive transport across intestinal...

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

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...
