Insights
High density lipoproteins (HDL) are crucial for a healthy pregnancy. Impaired HDL function, not just cholesterol levels, can lead to adverse pregnancy outcomes like preterm birth and preeclampsia.
Area of Science:
- Cardiovascular Science
- Reproductive Biology
- Inflammation Research
Background:
- High density lipoproteins (HDL) were initially linked to cardiovascular disease (CVD) through cholesterol levels.
- Current understanding emphasizes HDL composition and function over cholesterol levels in disease processes, particularly those involving inflammation.
Purpose of the Study:
- To review the role of HDL in maintaining a healthy pregnancy.
- To explore how impaired HDL function may contribute to adverse pregnancy outcomes.
Main Methods:
- Literature review of studies on HDL during pregnancy.
- Analysis of recent evidence on HDL composition and function changes in pregnancy.
Main Results:
- Pregnancy is an inflammatory state where excessive inflammation increases risks for maternal and fetal health.
- Limited studies show HDL composition and function change during pregnancy, especially in cases of adverse outcomes.
- Impaired HDL function is implicated in adverse pregnancy outcomes such as preterm birth and preeclampsia.
Conclusions:
- HDL composition and function are critical for a healthy pregnancy.
- Dysfunctional HDL may be a significant factor in adverse pregnancy outcomes.
- Further research is needed to fully elucidate HDL's role in pregnancy complications.
Background:
High density lipoproteins (HDL) were first linked to cardiovascular disease (CVD) over 30 years ago when an inverse relationship was shown between CVD and HDL-cholesterol levels. It is now apparent that HDL composition and function, not cholesterol levels, are the pertinent measurements describing HDL's role in various disease processes, especially those with subclinical or overt inflammation.
Scope Of Review:
Pregnancy is also an inflammatory state. When inflammation becomes excessive during pregnancy, there is an increased risk for adverse outcomes that affect the health of the mother and fetus, including preterm birth and preeclampsia. Though studies on HDL during pregnancy are limited, recent evidence demonstrates that HDL composition and function change during pregnancy and in women with adverse outcomes.
General Significance:
In this review, we will discuss how HDL may play a role in maintaining a healthy pregnancy and how impairments in function could lead to pregnancies with adverse outcomes.
