Evaluation of methylenetetrahydrofolate reductase (MTHFR) activity and the levels of homocysteine and malondialdehyde (MDA) in the serum of women with preeclampsia

ABSTRACT

Background

Methylenetetrahydrofolate reductase (MTHFR) has a key role in converting homocysteine to methionine so its deficiency might cause homocysteine accumulation and arterial destruction. The aim of this study was to evaluate the activity of methylenetetrahydrofolate reductase (MTHFR), homocysteine, and MDA levels in preeclampsia patients.

Material and Methods

In this case–control study, 30 preeclampsia patients and 30 healthy pregnant women as control group were selected and matched for maternal age, gestational age, and BMI. Preeclampsia was confirmed by examining hypertension and urinary proteinuria. Serum homocysteine and MDA level as well as MTHFR activity were measured manually.

Results

Homocysteine and MDA levels were significantly different between women with preeclampsia and normal pregnancies (p-value <0.001). Also, the results indicate that MTHFR activity in the two groups was statistically different (p-value <0.001).

Conclusion

It can be concluded that the regulation of homocysteine and its metabolic enzymes plays a significant role in controlling blood pressure and consequently in the pathophysiology of Preeclampsia and it can be a goal for prevention and treatments.
