Lipoprotein A profiles in Arab newborns.
Summary
Newborns have low Lipoprotein A (LpA) levels, which are higher in females. These levels are not linked to maternal factors, birth weight, or BMI, indicating early life cardiovascular risk is independent of these variables.
Area of Science:
- Cardiovascular Science
- Neonatal Research
- Lipid Metabolism
Background:
- Lipoprotein A (LpA) is a genetically determined lipoprotein.
- LpA is an independent risk factor for premature atherosclerosis and cardiovascular diseases.
- Coronary heart disease is a significant cause of mortality in Kuwait.
Purpose of the Study:
- To measure serum LpA concentrations in Arab newborns.
- To establish reference values for neonatal LpA.
- To investigate the relationship between neonatal LpA and maternal/infant factors.
Main Methods:
- Serum LpA concentration was analyzed in cord blood.
- 107 Arab newborns were studied.
- Enzyme-linked immunosorbent assay (ELISA) was used for LpA analysis.
Main Results:
- Mean LpA was 54.8 mg/L (median 33 mg/L), with most below 100 mg/L.
- Female infants had significantly higher mean LpA levels than males (77.27 vs 40.2 mg/L).
- Neonatal LpA was not influenced by maternal characteristics, delivery type, birth weight, or BMI.
Conclusions:
- Neonatal LpA concentration is generally low at birth.
- LpA levels at birth are independent of maternal characteristics, birth weight, and BMI.
- Early life LpA development is not associated with common neonatal factors.
