Abstract
The purpose of this study was to determine the effect of urinary
tract infection (UTI) on antioxidant systems and lipid
peroxidation (LPO) levels during pregnancy. We also
investigated if these antioxidant systems and LPO levels differed
in each trimester. One hundred forty-three nonpregnant women, as a
control group, and 77 pregnant women were included in the study.
Urine cultures were performed according to standard techniques.
Catalase (CAT), superoxide dismutase (SOD), and LPO levels were
measured using a spectrophotometer. UTI was observed in 14 of
77 pregnant women and the isolated microorganisms were
Escherichia coli, Klebsiella pneumoniae, and
Staphylococcus saprophyticus. CAT, SOD, and LPO levels
were increased in pregnant women compared with nonpregnant women
