Ferrous iron administration during pregnancy and adaptational oxidative stress (Pilot study).

UNLABELLED
The purpose of this investigation was to measure the effect of ferrous iron therapy on indices of oxidative stress in pregnant women.


MATERIAL AND METHODS
Nineteen healthy pregnant women with borderline anemia were subjected to per oral ferrous iron in prophylactic doses (36 mg daily, +Fe group, n=13) or did not get any treatment (-Fe group, n=6). The indices measured in two time-points were: conjugated dienes, lag phase of low-density lipoproteins, total antioxidant activity of the serum, total glutathione and its fractions, protein carbonyls, catalase, ferritin, serum iron and unsaturated iron binding capacity.


RESULTS
All women had high values of conjugated dienes, total antioxidant activity and short lag phases of low-density lipoproteins in both time points. Elevated values of oxidized glutathione in both groups increased about 2-fold and reached a significant difference level (p=0.02) by the end of the test period.


CONCLUSION
Low doses of per oral ferrous iron did not change deleteriously the physiological pattern of parameters of oxidative stress in our small group of healthy pregnant non-smokers but the elevation of oxidized glutathione might imply on the elevation of risk.
