Oral Progesterone and Low Dose Aspirin in the Prevention of Preeclampsia

2014-08-27 03:28:56 | BioPortfolio


Recent advances have shown that certain proteins may be present in a pregnant woman's blood very early in pregnancy which can predict who is at the highest risk for developing preeclampsia. These proteins can be measured and may be used to predict a woman's risk of developing preeclampsia.

Special placental cells called endovascular cytotrophoblasts are needed in the early formation of the placenta. These placental cells invade the maternal blood vessels in the formation of the maternal-placental blood interface. HLA-G is a protein produced by the placental cells and prevents these special cells from being rejected by the mother's immune system. Recent studies have indicated that the level of HLA-G is decreased in placentas from mothers with preeclampsia. Progesterone, a naturally occurring hormone produced in pregnancy, has been shown to increase the production of HLA-G in the placental cytotrophoblast cells.

In regards to the treatment of preeclampsia, studies have shown that low dose aspirin if given to mothers who have had severe early preeclampsia, lowers the risk for having preeclampsia again. This study aims to show that low dose aspirin combined with progesterone will decrease the risk of preeclampsia in pregnant women with a history of preeclampsia in a previous pregnancy. Data generated will determine levels and ratios of blood proteins that are predictive of preeclampsia at specific gestational ages.

Medical and Biotech [MESH] Definitions

A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)

Asthmatic adverse reaction (e.g., BRONCHOCONSTRICTION) to conventional NSAIDS including aspirin use.

A drug combination of aspirin and dipyridamole that functions as a PLATELET AGGREGATION INHIBITOR, used to prevent THROMBOSIS and STROKE in TRANSIENT ISCHEMIC ATTACK patients.

The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)

A salicylate derivative and anti-inflammatory analgesic with actions and side effects similar to those of ASPIRIN.
