Insights

Follow-up care for children diagnosed with familial hypercholesterolemia (FH) via cascade screening is insufficient. Improved education and structured follow-up are crucial for managing cholesterol and reducing cardiovascular risk in these young patients.

Area of Science:

  • Pediatric Cardiology
  • Genetics
  • Public Health

Background:

  • Familial hypercholesterolemia (FH) is a genetic condition leading to high cholesterol levels.
  • Early diagnosis and management are critical for preventing cardiovascular disease.
  • Cascade screening aims to identify affected individuals and their relatives.

Purpose of the Study:

  • To evaluate the follow-up care provided to children diagnosed with FH through a nationwide DNA-based cascade screening program in the Netherlands.
  • To identify factors influencing physician consultation and treatment initiation in these children.

Main Methods:

  • A nationwide DNA-based cascade screening program was utilized for FH diagnosis.
  • Questionnaires were sent to parents of diagnosed children (0-18 years) 18 months post-diagnosis.
  • Data collected included demographics, family history, physician consultations, and treatment details.

Main Results:

  • 207 questionnaires were analyzed from children with FH (mean age 10.9 years at diagnosis).
  • 79% of children consulted a physician, with general practitioners and lipid specialists being most common.
  • Physician consultation was predicted by LDL-C levels and family history; medication use by age, LDL-C, and parental education.

Conclusions:

  • The current follow-up for children with FH diagnosed via cascade screening is inadequate.
  • Enhanced education for patients, parents, and physicians is needed.
  • A structured follow-up protocol is essential to improve LDL-C control and reduce cardiovascular risk in children with FH.

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Genetic Screens02:46

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...

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)...

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

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...
