Aim: Miscarriages are becoming increasingly important problem nowadays. First trimester pregnancy loss frequency in women of reproductive age is increasing. In this study, it is aimed to show the possible relationship between first trimester pregnancy losses and PON1 and ARY activities. Material and Method: 25 pregnant healthy women (Group 1) and 25 women with first trimester miscarriage (Group 2) in 6-14 gestational weeks were included in this study. Paraoxonase 1 and arylesterase activities of the sera samples were investigated using fully automated colorimetric methods. ANOVA test was used to compare the groups. Results: PON1 and ARY activities are statistically significantly lower in pregnant women with first trimester miscarriage compared to healthy pregnant women in first trimester analyzed by Anova test (p<0.05). Conclusion: The results of this study showed that paraoxonase 1 and arylesterase antioxidant enzyme activities can be evaluated as significant predictive clinical laboratory parameters in first trimester pregnancy losses. If this study is confirmed with larger patient groups, our research results will gain more value.
