Child-Parent Familial Hypercholesterolemia Screening in Primary Care

Area of Science:

• Cardiovascular Medicine
• Genetics
• Pediatrics

Background:

• Familial hypercholesterolemia (FH) is an inherited condition leading to premature cardiovascular disease.
• Child-parent screening aims to identify individuals at high risk for FH.
• The efficacy and feasibility of FH screening in primary care settings were evaluated.

Purpose of the Study:

• To assess the effectiveness of child-parent screening for familial hypercholesterolemia in primary care.
• To determine the feasibility of implementing FH screening during routine pediatric immunization visits.

Main Methods:

• Capillary blood samples were collected from 10,095 children aged 1-2 years during immunization visits.
• Cholesterol levels were measured, and genetic testing for FH mutations was performed.
• Screening criteria included elevated cholesterol and/or identified FH mutations in children and their parents.

Main Results:

• The overall mutation prevalence for FH was 1 in 273 children.
• Using a cholesterol cutoff of 1.53 multiples of the median (MoM), 0.3% of children had positive screening results.
• A combined approach identified 40 children and 40 parents with positive screening results for FH.

Conclusions:

• Child-parent screening for FH is feasible in primary care during routine child immunization visits.
• Screening identified individuals at high risk for cardiovascular disease, with approximately 8 individuals per 1000 children screened.
• This strategy facilitates early identification and management of FH.
