Aim We aimed to investigate the relationship of maternal serum levels of S100-B, PAPP-A and IL-6 with severe preeclampsia. Materials and methods This prospective case-control study consisted of 27 severe preeclamptic and 36 healthy singleton pregnancies. The groups were matched for parity, maternal age and body mass index. Maternal blood sampling for S100B, PAPP-A and IL-6 was performed at the morning after an overnight fasting. Results S100-B concentrations were significantly higher in severe preeclampsia group (0.09 +/- 0.05 vs. 0.13 +/- 0.01 lg/L; p = 0.025). PAPP-A levels were higher (196.54 +/- 21.56 vs. 208.80 +/- 23.97 mIU/ml; p = 0.707) and IL-6 levels were lower in severe preeclamptic group (68.79 +/- 29.89 vs. 37.30 +/- 6.46 pg/ml; p = 0.372). AUC value for S100-B was calculated as 0.712. When cutoff level for serum S100-B for predicting severe preeclampsia was regarded as 0.0975 lg/L, sensitivity and specificity were found to be 81.4 % and 58.3 %, respectively. Pregnancies with C0.0975 lg/L S100-B levels had 12.75-fold increased risk for having CNS symptoms (OR 12.75; 95 % CI 2.69-60.28) and 3.27-fold increased risk for having HELLP syndrome (OR 3.27; 95 % CI 0.62-17.36). Conclusion Our results suggest that serum S100B levels may be a potential marker in severe preeclampsia for the severity of hypoperfusion both in placenta and brain pointing at subsequent risk of organ failure

GINEKOLOGIA POLSKA

Objective: To measure the intracranial translucency (IT) by establishing reference ranges in uncomplicated single ton Turkish pregnancies and to evaluate the association of IT with maternal serum biochemistry, gestational week, crown-rump length (CRL) measurement, nuchal translucency (NT) and ductus venosus Doppler velocimetry. Materials and methods: 190 uncomplicated singleton pregnancies were included in the study. IT, NT and CRL measurements between 11-14 gestational weeks were obtained with mid-sagittal plane. Two independent measurements were taken and averaged to obtain the final measurement used in the calculations. Statistical analysis was performed with SPSS for Windows 20.0 software package. Correlation analysis was used to determine the association between IT and NT, pregnancy-associated plasma protein-A (PAPP-A), free beta-human chorionic gonadotropin (f beta-hCG) and CRL length. A p-value of <0.05 was considered statistically significant. Results: The assessment rate of IT was 167/190 (87.89%). The mean CRL length, gestational week, NT and IT measurements were 63.63 +/- 10.05 mm, 12.28 +/- 0.75 weeks, 1.23 +/- 0.43 mm (range: 0.20-2.68) and 2,29 +/- 0,49 mm (range: 0.18-3.80), respectively. There was no significant correlation between IT and maternal serum PAPP-A MoM (r=-0.34, p=0.698) or maternal serum free beta-hCG MoM (r=-0.79, p=0.363), respectively. There was weak-but statistically significant correlation between IT with with maternal weight (r=0.172, p=0.047), CRL length (r=0.301, p<0.001), gestational week (r=0.286, p=0.001) and NT measurement (r=0.224, p=0.007), respectively. There was no significant association between IT with ductus venosus doppler pulsatility index (r=0.108, p=0.213). Conclusion: IT can be easily measured while scanning for NT. This study shows normal range values in healthy Turkish pregnancies. Consistent with recent data, our results show positive correlation with gestational week and CRL length. Maternal serum biochemistry does not have any effect on IT. Besides, our study highlights that IT is correlated with NT and adds newly to the literature that there is no correlation of IT with ductus venosus pulsatility index

GYNECOLOGICAL ENDOCRINOLOGY

We aimed to evaluate: (1) endometrial and ovarian tissue injury caused by the glucose toxicity in diabetic rat model and (2) the effect of GLP-1 analog (exenatide) on endometrial and ovarian diabetes induced injury with emphasizing the underlying mechanism. The study group composed of 24 female rats assigned randomly into 3 groups. Group 1 was the control group (n = 8) and received no treatment. Diabetes was induced by intraperitoneal injection of streptozocin for 16 rats which are further assigned randomly into 2 groups: 1 ml/kg intraperitoneal saline was given to Group-2 (diabetic non-treated control group, 8 rats) and 10 mu g/kg/day of intraperitoneal exenatide was given to Group 3 (exenatide treated group, 8 rats) for four weeks. After four weeks, blood samples were collected and hysterectomy with bilateral oophorectomy was performed for histopathological examination. Diabetes caused endometrial and ovarian tissue injury in rats (p < 0.0001). Serum transforming growth factor beta (TGF-beta), malonylaldehyde (MDA), pentraxin-3 (PTX-3) levels were higher in diabetic rats (p < 0.0001), whereas antimullerian hormone (AMH) was lower (p < 0.001). Serum levels of these markers reflected that Diabetes induced injury in the reproductive tract occured via oxidative stress, fibrosis and severe inflammation. Diabetes diminished ovarian reserve. Exenatide treatment improved the histological degeneration and fibrosis in the endometrium and ovary with concomitant decrease in inflammatory and oxidative stress markers (p < 0.05). Exenatide also improved ovarian reserve (p < 0.05). Glucose toxicity occured severely in ovary and endometrium in DM. After exenatide treatment; ovarian and endometrial injury and fibrosis seems to decrease significantly. The effects of exenatide in rat models give hope to prevent the women with DM from premature ovarian failure and endometrial dysfunction

JOURNAL OF MATERNAL-FETAL & NEONATAL MEDICINE

Objective: The aim of the present study was to evaluate changes in maternal serum neutrophil gelatinase-associated lipocalin (NGAL) and procalcitonin (PCT) concentrations in preeclampsia. Material and method: This case-control study consisted of 40 preeclamptic and 40 healthy singleton pregnancies matched for age and body mass index. Serum NGAL and PCT levels were compared between the groups. Diagnostic performance and clinical association of these markers were evaluated. Results: NGAL and PCT concentrations were significantly higher in preeclamptic group (p < 0.0001 and p = 0.001, respectively) and their levels were correlated with the severity of the preeclampsia. There were significant positive correlation between these markers and mean arterial pressure (MAP) and spot urine protein excretion. There was negative correlation between NGAL and apgar scores and fetal birth weight. Pregnancies with higher NGAL (OR: 4.89; 95% CI: 1.81-13.21) and higher PCT (OR: 6.67; 95% CI: 2.44-18.21) concentrations had higher risk for preeclampsia. Conclusion: NGAL and PCT may be potential biomarkers for preeclampsia. Their levels increase significantly in preeclampsia and they are related to the severity of the disease. These results are in agreement with the generalized endothelial damage and persistant inflammatory status in preeclampsia. NGAL may also be an indicator for adverse neonatal outcomes with decreased placental hypoperfusion

Maternal serum ADAMTS-9 levels in gestational diabetes: a pilot study

Objective: Gestational diabetes mellitus (GDM) is characterized with insulin resistance which is diagnosed during pregnancy. Although pregnancy is a diabetogenic state, not all women develop GDM. Genetic factors together with enviromental factors cause the maladaptation of maternal pancreas to this diabetogenic state and GDM develops. ADAMTS-9 is a recently recognized molecule whose genetic variants have risk of GDM. Decreased levels have already been shown in fetal membranes. Maternal serum levels of this protein have not been studied yet. We hypothesized that the alteration of ADAMTS-9 expression should cause changes in maternal serum levels which further could help to identify the disease and develop new treatment strategies. Materials and methods: This prospective case–control study is consisted of 27 pregnancies with GDM and 30 healthy singleton pregnancies matched for matenal age, gestational week, and maternal weight. GDM diagnosis was made with 2-h 75 g oral glucose tolerance test. ADAMTS-9 levels were compared between groups. Results: ADAMTS levels were 3.62 ± 0.33 ng/dL (range: 3.04–4.23) in GDM group and 4.65 ± 1.70 ng/dL (range: 3.07–8.21) in control group (p < 0.001). ADAMTS levels were not affected by maternal age, gestational age, and maternal weight. Conclusion: ADAMTS-9 levels were significantly lower in GDM pregnancies. This may help to understand the mechanism of GDM pathogenesis. In future, target treatments with ADAMTS proteins may help to improve the severity of diabetes pathogenesis. © 2016 Informa UK Limited, trading as Taylor & Francis Group

Use of the modified myocardial performance index for evaluating fetal cardiac functions in pregestational diabetic pregnancy babies

The aim of this study is assessment of importance of use of the modified myocardial performance index (Mod-MPI) for the evaluation of foetal cardiac function in foetuses of women with pregestational diabetes mellitus (PDM). In this study, data of 30 pregnant patients aged 18–45 years diagnosed with PDM and 30 pregnant women aged 18–45 years with normal pregnancy and their babies were evaluated. Foetal echocardiographic and doppler measurements, foetal biometric measurements, umbilical artery and ductus venosus pulsatility indexes were measured in both PDM and control groups. The Mod-MPI was significantly higher in foetuses of PDM women. Many influences especially cardiac and postpartum complications are observed in infants of PDM women. The Mod-MPI is a simple and useful method for assessing foetal ventricular function. Our study has shown that PDM is associated with foetal ventricular dysfunction.Impact statementWhat is already known on this subject? Although MPI is frequently used in routine clinical assessment of neonates, it is not used adequately in foetuses. Many influences especially cardiac and postpartum complications are observed in infants of PDM women. However, there are few studies focussed specifically on the assessment of foetal cardiac function in PDM. What do the results of this study add? MPI, which shows both diastolic and systolic functions is independent of ventricular anatomy and foetal heart rate, was found significantly higher in diabetic mother foetuses, can be said to be a valuable parameter in evaluating foetal cardiac functions globally. What are the implications of these findings for clinical practice and/or further research? Our study has shown that foetuses PDM are associated with foetal ventricular dysfunction. For this MPI measurement can be routinely performed at foetal cardiac measurements in foetuses of PDM mothers. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group

The impact of invasive prenatal testing on anxiety and sleep quality in pregnant women with a screen-positive result for aneuploidy

Purpose: Prenatal anxiety has negative effects on pregnancy and neonate. Both screening tests and invasive diagnostic tests are associated with elevated anxiety level. But a normal fetal karyotype result could improve the anxiety level in high-risk patients. We hypothesized that patients who prefer follow-up without karyotyping may experience increased anxiety and sleep impairment until delivery. Our aim was to determine the effect of invasive diagnostic test decision on anxiety and sleep quality in women with a positive screening result. Methods: 132 women were included for the study and three groups were described. The invasive group consisted of women who underwent invasive procedure after a screen-positive test result, the follow-up group consisted of women who preferred non-invasive follow-up after a screen-positive result and the control group consisted of women with screen-negative test results. Participants were evaluated with the State-Trait Anxiety Inventory (STAI) and the Pittsburgh Sleep Quality Index (PSQI) after genetic counseling. They were asked for completing the same questionnaires in the third trimester to establish the course of anxiety and sleep quality throughout pregnancy. Results: STAI scores were significantly higher in both screen-positive groups than in the control group in the first evaluation (p < 0.001). STAI scores decreased in the invasive group and controls while PSQI scores did not significantly change during the course of the pregnancy. However, the anxiety level and sleep quality were worsened over time in the follow-up group. Conclusion: Screen-positive women who preferred to follow up had higher anxiety level and worse sleep quality in the later stages of pregnancy. We concluded that invasive prenatal diagnostic tests could improve anxiety and sleep quality in pregnant women with a screen-positive result for aneuploidy. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group

Maternal serum perlecan levels in women with preeclampsia

Objective: Perlecan is an extracellular matrix proteoglycan suggested to maintain endothelial functions. We aimed to measure maternal serum perlecan levels in different preeclampsia phenotypes. Methods: This study included 50 women with preeclampsia and 30 healthy pregnant women. Results: Serum perlecan levels were significantly higher (p = 0.016) in preeclamptic women with severe features(n = 23) than preeclampsia patients(n = 27). There were no statistically significant differences in serum perlecan levels between the early-onset preeclampsia(n = 25), late-onset preeclampsia(n = 25), and healthy pregnancies. Conclusion: Our findings suggest that preeclamptic women with severe features have higher serum perlecan levels than women with preeclampsia. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group
