To determine the serum thiol/disulphide homeostasis in preeclampsia and to investigate association with clinical parameters.Forty-three pregnant women 43 healthy, uncomplicated pregnancies were included study. Native thiol, disulphide, total thiol concentrations measured by a novel automated method.The native levels significantly lower when compared healthy group (p < 0.001). There significant correlations among homeostatic parameters preeclampsia.Serum may have role pathogenesis can be...

Abstract Our aim was to investigate whether any hematological changes readily detectable by simple complete blood count (CBC), as well fasting and postprandial total serum bile acid (SBA) levels, have diagnostic values for the prediction of adverse pregnancy outcomes in intrahepatic cholestasis (ICP). A prospective, case control study carried out including 217 pregnant women (117 with ICP 100 healthy controls). The main outcome measures investigated were preterm delivery, APGAR scores,...

Placenta previa (PP) is a potential life-threatening pregnancy complication. Pro-brain natriuretic peptide (ProBNP), creatine kinase (CK), cardiac form of CK (CK-MB) and Troponin I are circulatory biomarkers related to functions. We aimed determine whether these PP placenta accreta.In this case-control study, fifty-four pregnant women who attended our tertiary care center for perinatology with the diagnosis totalis, them, 14 patients accreta were recruited as study groups. Forty-six...

Abstract Morbidly adherent placenta (MAP) is a growing concern currently and still diagnostic challenge for obstetricians. As emergency hysterectomy due to unscheduled delivery in MAP carries significant risks, we aimed evaluate whether first second trimester serum analytes may be used the prediction of requiring hysterectomy. A retrospective chart review all identified cases previa totalis with without was performed. total 316 pregnant women diagnosed as were included analysis. Cases...
