INTRODUCTION
Preeclampsia is one of the important diseases of
pregnancy. It complicates 7% to 10% of all pregnancies
and is a leading cause of both maternal and perinatal
morbidity and mortality worldwide.
1
Preeclampsia is
defined as a combination of high blood pressure
(hypertension), swelling (edema) and protein in the urine
(proteinuria) developing after the 20
th
week of
pregnancy.
2
The etiology of this relatively common
medical complication of pregnancy however remains
unknown.
2
Hypertensive disorders account for 40000
maternal deaths annually.
3
It stands next to hemorrhage
and embolism among pregnancy related cause of death.
4
The greatest impact is in developing countries, where it
accounts for 20 - 80% of the strikingly increased
maternal mortality.
5
Preeclampsia is more common in developing countries
due to their low dietary intake of essential minerals and
vitamins. Pregnant women in developing countries have
been reported to consume diets that are low in minerals
and vitamins.

An inadequate dietary intake might be

ABSTRACT
Background: Preeclampsia is one of the major causes of maternal and fetal morbidity and mortality. Though the
etiology is obscure, studies indicate the role of oxidative stress and antioxidants may have a role in the prevention of
preeclampsia. Micronutrients such as copper and zinc are involved in the antioxidant defense mechanism.
Methods: The present study was undertaken in a medical college hospital in coastal South India to assess the serum
levels of zinc and copper in women with preeclampsia and to compare them with normal pregnant women. The blood
samples from 60 preeclamptic women and an equal number of controls were analyzed for zinc and copper levels.
Outcome of pregnancy was analyzed and compared. Data were expressed as mean ± standard deviation. Comparison
of levels of the elements between the two groups was performed by independent t test and Chi square test and P value
of <0.05 was considered as statistically significant.
Results: The serum zinc and copper levels were significantly lower in the preeclamptic group compared to the
normotensives. Also preeclamptic women were older, their BMI was higher and birth weight of babies lower
compared to normotensives.
Conclusions: Increased knowledge about the importance of specific antioxidant micronutrients and their part in
successful pregnancy outcome should be the focus for future health strategies. Low levels of maternal copper and zinc
are related to preeclampsia and might have a causal role in this disease. Further investigation is needed to establish the
role of these elements in this dangerous condition of pregnancy.
