[Reference values for apolipoproteins and HDL-2/HDL-3 in childhood]
Insights
This study establishes reference values for apolipoproteins and HDL-cholesterol, crucial for early cardiovascular disease risk assessment. These values change with age, highlighting the importance of early diagnosis and monitoring for children.
Area of Science:
- Biochemistry
- Clinical Chemistry
- Epidemiology
Context:
- Epidemiological studies link high apolipoprotein B or low HDL-2 serum concentrations to increased cardiovascular disease risk.
- Establishing age-dependent reference values for key lipoproteins is essential for early diagnosis and intervention.
- Understanding lipoprotein dynamics in early life is critical for predicting future cardiovascular health.
Purpose:
- To establish age-dependent reference values for serum apolipoproteins (ApoB, ApoA-I, ApoA-II) and HDL-cholesterol fractions (HDL-2, HDL-3).
- To provide a basis for early diagnosis and therapeutic strategies for cardiovascular diseases.
- To analyze the developmental trends of these lipid parameters in infants and children.
Summary:
- Serum concentrations of apolipoproteins and HDL-cholesterol fractions exhibit significant age-dependent variations from birth.
- Apolipoprotein B shows a more pronounced increase than apolipoprotein A-I and HDL-2 during the first year of life.
- The apolipoprotein B/A-I ratio, a key cardiovascular risk indicator, also increases notably in early childhood.
Impact:
- Facilitates earlier and more accurate identification of individuals at risk for premature cardiovascular diseases.
- Supports the development of targeted preventative strategies and personalized therapies based on lipoprotein profiles.
- Enhances clinical decision-making by providing normative data for pediatric lipid analysis.
Abstract:
It is known from epidemiological studies, that high apolipoprotein B or low HDL-2 concentrations in serum are correlated with an increased risk for premature cardiovascular diseases. It was the aim of this study to generate reference values for apolipoproteins and HDL-cholesterol fractions to accomplish early diagnosis and therapy. All concentrations are age depending, being low at birth and increasing during the first years of life. This rise is more pronounced in apolipoprotein B than in apolipoprotein AI and HDL-2. Apolipoprotein II and HDL-3 reach later childhood values as early as at the end of the first month of life. The ratio of B and AI, which is a very good indicator for an increased risk for premature cardiovascular diseases, moves also distinctively upward during the first year of life.
