Evaluation of first- and third-trimester afamin levels in preeclampsia.

OBJECTIVE: The aim of this study was to investigate serum afamin levels in the first and third trimesters in preeclampsia. METHODS: Serum samples from 118 patients in the first and third trimesters were analyzed. Serum samples were collected from pregnant women who had enrolled in the first trimester. Blood was then collected from pregnant women who had developed preeclampsia and from healthy controls in the third trimester. The collected blood samples were resolved for analysis, and serum afamin concentrations were measured in the first and third trimesters. Preeclampsia and healthy controls were compared. RESULTS: There was no significant difference between the control and preeclampsia groups in terms of age, body mass index, and smoking. Afamin levels in the first and third trimesters were higher in the preeclampsia group than in the control group (p<0.05). In the subgroup analysis of the preeclampsia group, afamin levels were higher in the early-onset preeclampsia group than in the late-onset preeclampsia group in the first and third trimesters (p<0.05). In the receiver operating characteristic analysis afamin levels were 96.23 ng/mL in the first trimester and 123.57 ng/mL in the third trimester as cut-off values for preeclampsia. CONCLUSION: Serum afamin levels are useful for predicting preeclampsia in the first trimester in pregnant women and can be used in clinical practice as a supportive biomarker for the diagnosis of preeclampsia in the third trimester. Meta-analyzes are needed to investigate the effect of afamin levels in the prediction and diagnosis of preeclampsia and to determine the cut-off value.

Maternal serum Sortilin-1 level as a potential biomarker for intrahepatic cholestasis of pregnancy.

Objective: Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disease related to pregnancy in women. Sortilin-1 is a sorting receptor belonging to the vacuolar protein sorting 10 (Vps10p) domain family, and recent studies have shown that Sortilin-1 has a distinct role in the pathogenesis of biliary fibrosis and cirrhosis. We aimed to evaluate maternal serum Sortilin-1 level as a potential biomarker in pregnant women with intrahepatic cholestasis.Materials and methods: A prospective observational cohort study was conducted. We enrolled 80 pregnant women, 49 with the diagnosis of intrahepatic cholestasis of pregnancy and 31 healthy controls. Then, we measured maternal serum Sortilin-1 levels using an enzyme-linked immunosorbent assay method and compared them between groups.Results: The mean Sortilin-1 level in the ICP group was higher than control group (3.3 ± 1.7 ng/mL vs. 2.0 ± 0.6 ng/mL, respectively, p < .001). The receiver operating characteristic curve (ROC) analysis based on maternal serum Sortilin-1 levels to predict the presence of ICP was 85.3% controls [area under the curve (AUC), 0.853; 95% CI, 0.738-0.938, p < .001]. The optimal cutoff value of Sortilin-1 was 2.24 ng/mL (71.4% sensitivity and 74.2% specificity) to detect intrahepatic cholestasis of pregnancy.Conclusion: Elevated maternal serum Sortilin-1 levels are associated with ICP and can be used as a disease biomarker. Sortilin-1 levels can be combined with total bile acids, transaminases, and blood coagulation profile in the follow-up of ICP.

Prediction of gestational diabetes mellitus and perinatal outcomes by plasma zonulin levels.

PURPOSE: Zonulin has been shown to be associated with many metabolic disorders, including type 2 diabetes mellitus, metabolic syndrome, and obesity. In this study, we aimed to evaluate the association between maternal plasma zonulin levels and gestational diabetes mellitus (GDM) and its perinatal outcomes. MATERIALS: A total of 100 pregnant women, 56 with GDM and 44 controls, were included in this prospective case-control study. Maternal plasma zonulin levels were evaluated in each trimester. The association between zonulin levels and GDM, body mass index (BMI) and adverse perinatal outcomes was evaluated. The GDM predictability of zonulin levels for each trimester was analyzed with the receiver operator curve (ROC). RESULTS: Plasma zonulin levels were significantly higher in pregnant with GDM in all trimesters (p < 0.001; for all). Optimum cut-off values of plasma zonulin levels in predicting GDM: first trimester: 6.27 ng/mL, second trimester: 12.71 ng/mL, and third trimester: 18.38 ng/mL. BMI was significantly higher in pregnant women with GDM (30.5 vs 26.1; p < 0.001). Zonulin levels were significantly higher in pregnant women with GDM with overweight BMI [≥ 25-30 (kg/m2)] in all trimesters (p < 0.05; for all). Zonulin levels were significantly higher in pregnant women with composite adverse outcomes that included at least one of neonatal intensive care unit (NICU) admission, meconium-stained amniotic fluid, and 1st minute APGAR score < 7. CONCLUSION: Increased maternal plasma zonulin levels were associated with increased risk of GDM and adverse perinatal outcomes. Zonulin may be a potential marker to predict GDM risk and perinatal outcomes.

Myometrial thickness overlying cesarean scar pregnancy is significantly associated with isthmocele formation in the third month of the postoperative period.

OBJECTIVE: To determine some associated factors for isthmocele formation 3 months after the treatment of cesarean scar pregnancy (CSP). MATERIALS AND METHODS: This is a prospective consecutive case series of CSP managed by fertility preservation modalities at a single tertiary care center from May 2016 to March 2019 (n=95). Patients with a diagnosis of CSP were identified and followed prospectively to collect data on the patients' demographics; detailed medical, surgical, and social history; symptoms; imaging and laboratory parameters at the time of CSP diagnosis and during treatment; treatment modalities, myometrial thickness; and outcomes in terms of isthmocele formation. RESULTS: Mean myometrial thickness overlying scar pregnancy was significantly lower in the group with isthmocele formation, and the mean gestational age of scar pregnancy was also significantly lower in the group with isthmocele formation following treatment of scar pregnancy (p<0.05). Multivariate regression analysis was conducted to determine associations between certain variables and isthmocele development, which revealed that the gestational age of scar pregnancy and myometrial thickness were significantly associated with isthmocele formation. CONCLUSION: Myometrial thickness and gestational age of scar pregnancy were significantly associated with isthmocele formation 3 months after treatment.
