What is the impact of increased level of homocysteine during pregnancy?
Table of Contents
Homocysteine is an intermediate metabolite implicated in the risk of placenta-mediated complications, including preeclampsia, placental abruption, fetal growth restriction, and pregnancy loss.
Does folic acid increase homocysteine levels?
Folic acid is the most important dietary determinant of homocysteine; daily supplementation with 0.5 to 5.0 mg typically lowers plasma homocysteine levels by about 25 percent.
What is the relationship between folate and homocysteine?
Folate deficiency is associated with raised homocysteine, and raised homocysteine is associated with increased risk of cardiovascular disease. In a few studies, folate nutritional status (either intake or blood levels) is correlated directly with cardiovascular disease risk.
Is homocysteine elevated in folate deficiency?
Folate deficiency also results in elevated levels of homocysteine because of reduced activity of the methionine synthase–catalyzed reaction. Total homocysteine concentration, which comprises the sum of all homocysteine species in plasma/serum, including free and protein-bound forms, can be measured in plasma or serum.
How can I lower my homocysteine during pregnancy?
The usual recommendation in women with elevated homocysteine levels is to take high doses of folic acid and B vitamins to improve the body’s metabolism of homocysteine.
Can high homocysteine levels cause miscarriage?
In particular, high levels of homocysteine have been found in 25% (10) of women with unexplained early fetal loss. Conclusion: Hypercystinemia, as a consequence of an interaction between a primary genetic defect and a nutrition condition (folate deficiency), may be a cause of recurrent miscarriages.
How does folic acid lower homocysteine?
Folic acid, vitamin B6, and vitamin B12 deficiency inhibits the breakdown of homocysteine, causing plasma levels to rise. 1 Therefore, folic acid supplementation has been shown to lower plasma homocysteine levels.
How long does it take folate to lower homocysteine?
If you start taking folate or vitamin B supplements, you should have your homocysteine level rechecked after 8 weeks. If your homocysteine level remains high, your doctor may have you try a higher dose. You may need to have some tests to see if you have another health condition that causes high homocysteine levels.
What is elevated in folate deficiency?
In folate deficiency, homocysteine levels are elevated and MMA levels are normal. In vitamin B12 deficiency, both homocysteine levels and MMA levels are elevated.
What blood test shows homocysteine?
A homocysteine test is a blood test. It measures the amount of homocysteine, an amino acid in the body. The test is often used to diagnose vitamin B6, B9 or B12 deficiency. People with elevated homocysteine may have a higher risk for cardiovascular disease.
Should homocysteine levels be checked in women with recurrent miscarriage?
There are no formal recommendations to check homocysteine levels in women with recurrent miscarriage, and there are no universally recommended treatment protocols for handling elevated homocysteine levels in women who are found to have them.
What are the risks of elevated homocysteine levels during pregnancy?
Elevated homocysteine is a confirmed risk factor for other problems in pregnancy including: Reduced fertility. Congenital developmental defects, such as neural tube defects like anencephaly. Preeclampsia.
What is homocysteine and what does it do?
Homocysteine is a type of amino acid that is naturally found in the body. At normal levels, it is not harmful, but elevated levels have been found to be associated with miscarriage as well as heart disease. An elevated level of homocysteine in the blood results in a condition known as hypercoagulability.
What does an elevated homocysteine level mean?
An elevated level of homocysteine in the blood results in a condition known as hypercoagulability. The word coagulation refers to blood clotting, and hypercoagulability means that blood clots more easily than it should.
