Introduction: Preeclampsia is one of the major causes of maternal mortality and also from the important causes of major fetal, neonatal, and maternal complications. Different studies have mentioned that infections during pregnancy are possible pathophysiology of preeclampsia. This study was performed with the aim to evaluate the association of asymptomatic bacteriuria (ASB (and preeclampsia in pregnant women.
Methods: This cross-sectional study was performed in 2012 on 320 pregnant women referred to Amiralmomenin and Shafa hospitals of Semnan. 160 pregnant women who presented preeclampsia after 20 weeks of gestational age were selected as case group and 160 healthy pregnant women at the same gestational age as control group. Data were analyzed using SPSS software (version 16), t-test, and Chi-square test. PResults: The prevalence of ASB was 13.8% (22 cases) in case group and 5.6% (9 cases) in control group. The association between preeclampsia and asymptomatic bacteriuria was significant in pregnant women (P=0.027), so that, the possibility of asymptomatic bacteriuria in women with preeclampsia was 2.59 times of control group.
Conclusion: Asymptomatic bacteriuria is a factor effective on preeclampsia, therefore, screening of asymptomatic bacteriuria on prenatal care are recommended.
