Insights

Familial hypercholesterolaemia (FH) is a genetic disorder causing high LDL cholesterol. Early detection and treatment in children, including revised criteria and updated goals, are crucial for preventing premature cardiovascular disease and improving life expectancy.

Area of Science:

  • Cardiovascular Genetics
  • Pediatric Endocrinology
  • Lipid Metabolism

Background:

  • Familial hypercholesterolaemia (FH) is a prevalent genetic disorder causing lifelong high LDL cholesterol (LDL-C).
  • FH presents as heterozygous (HeFH, ~1 in 300) or homozygous (HoFH, ~1 in 300,000), significantly increasing premature atherosclerotic cardiovascular disease (ASCVD) risk.
  • Despite available lipid-lowering therapies (LLTs), challenges persist due to limited awareness, underdiagnosis, and undertreatment, particularly in childhood.

Purpose of the Study:

  • To address challenges in FH detection and management through a consensus statement.
  • To present revised diagnostic criteria and updated LDL-C treatment goals for children with FH.
  • To provide guidance on managing FH in children, including treatment algorithms and transition to adult care.

Main Methods:

  • Review of current knowledge on FH pathogenesis and LLTs.
  • Development of revised diagnostic criteria to improve identification of genetic variants.
  • Proposal of updated LDL-C treatment goals and initiation timing for pediatric FH patients.

Main Results:

  • Emphasis on establishing pediatric screening programs to increase FH detection rates.
  • Revised diagnostic criteria are presented to better identify children with FH-causing genetic variants.
  • Updated LDL-C treatment goals and recommendations for starting LLTs before puberty (or from age 6 if needed) are proposed.

Conclusions:

  • Early diagnosis and treatment of FH in childhood are critical for normalizing life expectancy.
  • Implementing pediatric screening and revised diagnostic criteria can improve FH detection.
  • Optimal management, including timely LLT initiation and transition to adult care, is essential for improving outcomes in children and adolescents with FH.

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...

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...

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)...
Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...

Atherosclerosis IV: Nursing Management

Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...
