The relationship of oxidants and anti-oxidants in preeclampsia with reference to the dietary anti-oxidants vitamin C and vitamin E was investigated. Three groups of patients were studied in the third trimester of pregnancy: normotensives ( n = 32), mild pre-eclamptics ( n = 15) and severe pre-eclamptics ( n = 31) with a group of healthy non-pregnant women ( n = 18) serving as a control. Total anti-oxidant concentration, the concentrations of vitamin C, vitamin E, superoxide dismutase, uric acid and the concentration of total oxidant activity, as reflected by lipid peroxides, were measured in plasma or red blood cells. Total anti-oxidants and vitamin C concentrations were significantly lower in pre-eclamptic patients than in pregnant controls (P < 0.05), with the concentrations in the pregnant controls being significantly lower than in the non-pregnant controls (P < 0.05). There was no significant difference in vitamin E concentration for all four groups. Superoxide dismutase activity was significantly lower in the normal pregnancy group. Lipid peroxides were significantly increased in the three pregnant groups (P < 0.05) with no differences noted between these groups. The relationship of oxidants to anti-oxidants in pregnancy and pre-eclampsia is dependent on many factors but balance appears to be upset in pre-eclampsia. The reduction in anti-oxidant concentrations in pre-eclampsia suggests either a primary deficit or consumption of the anti-oxidants measured. Of the dietary anti-oxidants studied, vitamin C was most affected in pre-eclampsia.
