Introduction:
Preeclampsia is the leading cause of maternal and perinatal mortality and morbidity. Several studies have associated oxidative stress with the etiopathogenesis of preeclampsia but there is little evidence to link this with the appearance and severity of complications.Objective:
In this study we compared the plasma level of total antioxidant capacity (TAC) and malondialdehyde levels in plasma with the severity of preeclampsia.Material and methods:
A transversal comparative study was designed which included 56 patients in two groups, i.e., 28 patients with preeclampsia, of whom 14 had mild preeclampsia and 14 presented severe preeclampsia, and as a control group 28 normotensive women with a pregnancy of more than 28 weeks. Plasmatic antioxidant capacity and malondialdehyde were determined by ELISA. Follow-up was made to determine outcomes.Results:
In pregnancies without hypertension, total antioxidant capacity levels were 2679 ± 2014 mEq/l in normal pregnancy, but fell in patients with preeclampsia. However, the greatest impact was in women with severe preeclampsia (p < 0.05), but no significant differences were noticed in malondialdehyde levels between the groups.Conclusion:
Women with severe preeclampsia present a marked reduction in total antioxidant capacity
La preeclampsia es la causa principal de morbilidad y mortalidad materna y perinatal, y es la primera causa de admisión obstétrica en terapia intensiva. Varios trabajos asocian el estrés oxidativo con la etiopatogenia de la preeclampsia, pero existen pocas evidencias que lo relacionen con la gravedad y la aparición de complicaciones.
