a Istanbul University Cerrahpasa Medical Faculty , Obstetrics and Gynecology Division of Perinatology , Istanbul , Turkey.

Introduction: Isotretinoin, a synthetic derivative of vitamin A, is one of the most potent human teratogens, and is mainly utilized for the treatment of severe recalcitrant nodular acne. Retinoic acid embryopathy is well defined in the literature.

Case Report: The mother was referred for a fetal posterior fossa abnormality, first detected at 20 weeks of gestation. The mother used isotretinoin until 18 weeks gestation. Ultrasound examination revealed hypertelorism, cerebellar hypoplasia, vermian agenesis, truncus arteriosus, anotia, thymic aplasia, corpus callosum hypoplasia. An intrauterine diagnosis of fetal retinoid syndrome was confirmed by fetopsy after termination of pregnancy.

Conclusion: The typical findings of fetal retinoid syndrome can be visualized with ultrasound in early second trimester.

J Matern Fetal Neonatal Med 2016 7;29(15):2527-30. Epub 2015 Oct 7.

a Department of Obstetrics and Gynecology , Cerrahpasa School of Medicine, Istanbul University , Istanbul , Turkey .

Objective: The aim of the study is to evaluate maternal serum atrial natriuretic peptide (ANP) and brain-type natriuretic peptide (BNP) levels in patients with getational diabetes mellitus compared with a control group.

Methods: We have measured maternal serum ANP and BNP levels in 35 otherwise healthy and 45 gestational diabetic women between gestational week 24 and 28 referred to our unit in a cross-sectional study. Independent samples t-test or the Mann-Whitney U-test was used for comparison of two groups where appropriate.

Results: Mean maternal serum homeostasis model assessment of insulin resistance (HOMA-IR), HbA1c, fasting glucose and insulin levels in gestational diabetes mellitus (GDM) group were significantly higher than the control group (p < 0.01). Mean maternal serum ANP and BNP levels of women with GDM were significantly lower than the control group (12.9 ± 9.9 versus 34.8 ± 16.9 pg/ml, p < 0.001; 416.6 ± 209.7 versus 629.7 ± 162.2 mg/dl, p < 0.001, respectively). Maternal serum ANP and BNP levels were negatively correlated with insulin levels, HbA1c and HOMA-IR values (p < 0.05).

Conclusions: Maternal serum ANP and BNP levels are significantly lower in patients with GDM. These biomarkers might be valuable in clinical setting for identifying high-risk women for developing diabetes during pregnancy.

Serial ultrasonographic examination of the fetal thymus in the prediction of early neonatal sepsis in preterm premature rupture of membranes.

Gynecol Obstet Invest 2014 9;78(3):201-7. Epub 2014 Sep 9.

Maternal and Fetal Medicine, Obstetrics and Gynecology, Yuzuncu Yuzyil University, Van, Turkey.

Background/aims: To evaluate the diagnostic accuracy of fetal thymus transverse diameter (FTTD) in predicting fetal infection in preterm premature rupture of membranes (PPROM) and compare its accuracy with cord blood tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6).

Methods: Forty consecutive pregnancies complicated with PPROM between 26(1/7) and 36(6/7) gestational weeks were evaluated prospectively. Serial fetal ultrasonography follow-ups with 3-day intervals were performed beginning on the admission day. The FTTD was recorded on every ultrasonographic examination. Cord blood TNF-α and IL-6 values were measured after delivery.

Results: FTTD was decreased below 5% according to nomograms compared to the initial measurement in 45% of all PPROM cases. Decreased FTTD had a sensitivity of 100%, specificity of 73%, positive predictive value of 55%, and negative predictive value of 100% in predicting early neonatal sepsis. Cord blood TNF-α had a sensitivity of 80% and specificity of 90%, whereas IL-6 had a sensitivity of 90% and specificity of 63.3% in predicting early neonatal sepsis.

Conclusions: Assessment of the decrease in FTTD by serial ultrasonographic examinations is a promising 'prenatal' method for the early detection of early neonatal sepsis.

Women's Preferences of Method of Delivery and Influencing Factors.

Iran Red Crescent Med J 2013 Aug 5;15(8):683-9. Epub 2013 Aug 5.

Department of Obstetrics and Gynecology, Cerrahpasa Medical School of Istanbul University, Istanbul, Turkey.

Background: Currently, the rate of caesarean section has been substantially increased in developing and developed countries. To determine the factors causing such an increase, it is important to determine reasons for women to refuse vaginal delivery and preferring caesarean section.

Objectives: To determine Turkish women's attitudes and basal knowledge regarding vaginal delivery and caesarean section, as well as factors causing women to prefer caesarean section even when a medical indication does not exist.

Patients And Methods: This descriptive study consisted of 840 women, completing the questionnaire developed by the researchers.

Results: Mean age rate of participants was 39.8 ± 11.8 years. The most significant reasons of vaginal delivery preferred by participants (n = 685) were determined to be healthy and swift recovery period after delivery, whereas those preferred by participants (n=155) for caesarean section were being safer for babies, easier than vaginal delivery and a less painful method. Higher educational status, pregnancy after infertility treatment and undergoing caesarean section for the last delivery were determined to be among important factors affecting to choose caesarean section.

Conclusions: Information gained misleadingly and fears related to vaginal delivery were seen as factors affecting women's preferences for delivery. Thus, midwives are required to train both pregnant women during antenatal care and all women in society about methods of delivery and to give effective counseling.

Acromegaly is associated with higher frequency of female sexual dysfunction: experience of a single center.

Endocr J 2013 8;60(6):753-61. Epub 2013 Feb 8.

Division of Endocrinology and Metabolism, Department of Internal Medicine, Cerrahpasa Medical School, University of Istanbul, Istanbul, Turkey.

The aim of the study was to assess female sexual dysfunction (FSD), quality of life and depression status in female patients with acromegaly. Fifty-seven sexually active female patients with acromegaly disease (21 controlled, 36 uncontrolled) monitored by Cerrahpasa Medical School, Endocrinology and Metabolism out-patient clinic and age and body mass index-matched 46 healthy female subjects were included in the study. Sexual functions and status of depression in both patient and control groups were evaluated by using the Female Sexual Function Index Form (FSFI) and the Beck Depression Inventory (BDI), respectively. Quality of life was evaluated by using the Acromegaly Quality of Life (AcroQoL) Scale. Hormone levels were studied in the groups. The FSFI total score and desire, arousal, orgasm, and satisfaction domains in patients with acromegaly were significantly lower than in the healthy controls (p ≤ 0.0001). There was no difference between biochemically controlled and uncontrolled patients with acromegaly with respect to FSFI scores (p = 0.7). AcroQoL total score in female patients with controlled acromegaly and uncontrolled acromegaly were 46.33 ± 16.5% and 50.13 ± 18.21%, respectively (p = 0.53). The difference in BDI scores between controlled and uncontrolled acromegaly patients was not significant but they were significantly higher in the control group (p ≤ 0.0001). In the correlation analysis, a negative correlation was found between FSFI total and BDI score (r = -0.69, p< 0.001), age (r = -0.45, p< 0.001), and IGF-I (r = -0.28, p = 0.006). This study showed that sexual dysfunction and depression rates in female patients with acromegaly are higher than in healthy females.

Effects of amniotic and maternal CD-146, TGF-β1, IL-12, IL-18 and IFN-γ, on adverse pregnancy outcome.

J Matern Fetal Neonatal Med 2013 Jan 11;26(1):21-5. Epub 2012 Sep 11.

Department of Obstetrics and Gynecology, Cerrahpasa Medical Faculty of Istanbul University, Istanbul, Turkey.

Objective: Our aim was to determine the effects of maternal serum and amniotic fluid levels of cluster of differentiation 146 (CD-146), transforming growth factor (TGF)-β1, interleukin (IL)-12, IL-18, and interferon (IFN)-γ on intrauterine growth restriction and preterm labor.

Methods: In this retrospective cohort study, we included pregnant women who underwent amniocentesis at Istanbul University Cerrahpasa Medical School. Women were followed up to labor. The study group comprised 23 women with adverse pregnancy outcomes (intrauterine growth restriction and preterm labor), and the control group comprised 105 women with normal pregnancy outcome.

Results: The study group was further divided into two subgroups of preterm labor and intrauterine growth restriction. No significant differences were found for IL-12, IFN-γ, TGF-β1, or CD-146 levels in either plasma or amniotic fluid between the study and control groups. Serum IL-18 levels were similar, but the amniotic fluid level of IL-18 was significantly higher in the intrauterine growth restriction subgroup than that in the preterm labor subgroup and that in the control group (p < 0.01).

Conclusions: Increased IL-18 level in amniotic fluid may be a predictor for intrauterine growth restriction. IL-12, IFN-γ, TGF-β1, and CD-146 were not related to adverse pregnancy outcome.

The effects of 17β-estradiol plus drospirenone on anthropometric and biochemical measures of adiposity in menopausal women.

Arch Gynecol Obstet 2012 Nov 13;286(5):1233-9. Epub 2012 Jul 13.

Department of Obstetrics and Gynecology, Cerrahpasa Medical Faculty, Istanbul University, Istanbul, Turkey.

Purpose: To assess whether there are changes on anthropometric and biochemical measures of adiposity in pre- and postmenopausal women and in the latter before and after 6 months treatment with 17β-estradiol plus drospirenone.

Methods: Twenty postmenopausal and 20 premenopausal women were enrolled in a prospective comparative study. Postmenopausal women received 1 mg 17β-estradiol plus 2 mg drospirenone daily for 6 months. Measurements of body mass index (BMI), waist/hip ratio and plasmatic levels of insulin, glucose, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglyceride, leptin, adiponectin, orexin-A, glucagon-like peptide-1 (GLP-1) and ghrelin were performed in premenopausal (group 1) and postmenopausal women and in the latter before (group 2a) and after (group 2b) 6 months treatment with 17β-estradiol plus drospirenone.

Results: No significant changes in BMIs, insulin and glucose were observed between group 1 and 2a; and group 2a and 2b. GLP-1 levels were significantly increased in group 1 compared to group 2a (p = 0.035). Leptin levels were significantly increased (p = 0.001) and GLP-1 levels were significantly decreased (p = 0.021) in group 2b compared to group 2a. HDL was significantly decreased while LDL and triglyceride levels were significantly increased in group 2a compared to group 1. (p = 0.030, p = 0.001, p = 0.020; respectively) LDL was significantly decreased (p = 0.010) in group 2b compared to group 2a. GLP-1 had a positive correlation with orexin-A (p < 0.001, r = 0.520) and negative correlation with leptin (p = 0.008, r = -0.345).

Conclusion: Leptin was significantly higher and GLP-1 was significantly lower in women receiving 17β-estradiol plus drospirenone treatment. GLP-1 levels were significantly lower after the menopause compared to premenopausal levels. Orexin-A and GLP-1 were positively correlated.

Bladder exstrophy.

Fetal Pediatr Pathol 2012 Aug 20;31(4):225-9. Epub 2012 Mar 20.

Istanbul University, Cerrahpasa School of Medicine, Department of Obstetrics and Gynecology, Division of Maternal Fetal Medicine, Istanbul, Turkey.

Bladder exstrophy is a very rare congenital malformation in which the anterior wall of the bladder is absent, and the posterior wall is exposed externally. The differential diagnosis includes omphalocele, gastroschisis, and cloacal exstrophy. Ultrasound and Doppler examinations are the main diagnostic tools. Although mortality is low, termination of pregnancy should be discussed due to serious morbidities.

Multiple fetal anomalies in association with topiramate and oxcarbezepine treatment.

Fetal Pediatr Pathol 2012 Jun 13;31(3):154-8. Epub 2012 Mar 13.

Department of Obstetrics and Gynecology, Istanbul University, Cerrahpasa Medical Faculty, Istanbul, Turkey.

We present a case of a woman who used topiramate (100 mg) and oxcarbazepine (300 mg) continuously during pregnancy. Multiple fetal anomalies including limp defects of the lower extremities, pericardiac fluid collection, cardiomegaly, cleft lip and palate, absent right kidney, and dysplastic left kidney were found by ultrasonography. Labor was induced and anomalies were confirmed by autopsy. The malformation rate after exposure to oxcarbazepine in utero as a monotherapy was calculated to be 2.4%, which is compatible with the malformation rate seen in the general population. Topiramate is teratogenic in mice, rats, and rabbits, but there are very few reports about its teratogenicity in humans.

Remission of endometriosis by hyperbaric oxygen treatment in rats.

Reprod Sci 2011 Oct;18(10):941-7

Department of Obstetrics and Gynecology of Cerrahpasa Medical Faculty, Istanbul University, Istanbul, Turkey.

We designed this prospective, randomized controlled animal study to determine the effects of hyperbaric oxygen (HBO) on experimentally induced endometriosis in a rat model. Surgical induction of endometriosis was performed in 40, nonpregnant, female, Wistar-Albino rats at the Experimental Medicine Research Center of Istanbul University (DETAE). Four weeks later, the first and second laparotomies for volume measurement and peritoneal fluid (PF) collection were performed, and the rats were divided randomly into the study and control groups. The study group was exposed to HBO treatment for 6 weeks. Then, a third laparotomy was performed on all of the rats. The volume, histopathologic scores, Ki-67 labeling of the endometriotic implants, and the levels of tumor necrosis factor-α (TNF-α) in the PF were measured. The mean volume of the endometriotic implants in the study group was significantly lower than that of the control group at the end of the study (57.4 ± 12.5 vs 94.6 ± 17.2 mm(3)). The mean histopathological scores (1.60 ± 0.50 vs 2.42 ± 0.51), Ki-67 immunohistochemical scores (1.50 ± 0.51 vs 2.37 ± 0.49) of the endometriotic implants, and the TNF-α levels (5.33 ± 1.02 vs 8.16 ± 1.76 pg/mL) were significantly lower in the study group than in the control group. Hyperbaric oxygen treatment for 2 hours a day for 6 weeks resulted in significant remission of endometriosis in rats.

Protein oxidation markers in women with and without gestational diabetes mellitus: a possible relation with paraoxonase activity.

Diabetes Res Clin Pract 2011 Dec 31;94(3):404-9. Epub 2011 Aug 31.

Istanbul University, Cerrahpasa Medical Faculty, Department of Biochemistry, Istanbul, Turkey.

Aims: To clarify the levels of protein oxidation markers such as protein carbonyl (PCO), protein hydroperoxides (P-OOH), advanced oxidation protein products (AOPP) and nitrotyrosine (NT), as well as antioxidative enzymes such as paraoxonase (PON-1) in women with and without gestational diabetes mellitus (GDM).

Methods: The study was conducted on 23 women with GDM and 22 women without GDM. The levels of the P-OOH, AOPP, and PON-1 were determined by colorimetric methods; whereas NT and PCO levels were measured by ELISA.

Results: The concentrations of protein oxidation markers were significantly increased and PON1 activity was significantly decreased in GDM group compared to those of normal pregnant women. The control group showed a significant negative correlation between PON-1 and PCO (r=-0.451, p=0.027); whereas in GDM group, there was a significant positive correlation between P-OOH and HbA1c (r=0.89, p=0.001). There was no significant correlation between AOPP, PON-1, P-OOH, PCO, and HbA1c in either group.

Conclusions: There is evidence of a possible association between protein oxidation and decreased PON1 activity in GDM. The increase in protein oxidation parameters in the GDM group leading to decreased PON1 activity might, we think, create a predisposition for clinical complications in GDM group.

Perinatology Division of Obstetrics and Gynecology Department, Cerrahpasa Medical Faculty, Istanbul University, Istanbul, Turkey.

Aim: to compare short- and long-term complications of amniocentesis performed with 20G, 21G, and 22G needles.

Methods: this observational study included 793 pregnant women who underwent amniocentesis in the Perinatology Department of Cerrahpasa Medical Faculty, Istanbul University, Turkey. The patients were divided into three groups according to the needle size used for the procedure: 20G (Group 1), 21G (Group 2), and 22G (Group 3). The incidences of early and late complications were compared among groups.

Results: fetal loss rates did not differ among groups (Group 1=1.57%, Group 2=1.47%, Group 3=1.61%). Rates of vaginal bleeding (1.57%, 1.10%, and 0.81%, respectively), bloody amniotic fluid (2.32%, 6.23%, and 2.67%, respectively) and amniotic fluid leakage (1.57%, 1.10%, and 1.61%, respectively) were also similar among the three groups.

Conclusion: short- and long-term complications did not differ among amniocenteses performed with 20G, 21G, and 22G needles.

Treatment of symptomatic interhemispheric arachnoid cysts by cystoperitoneal shunting.

J Clin Neurosci 2010 Jun 19;17(6):700-5. Epub 2010 Mar 19.

Department of Neurosurgery, Sakarya Toyotasa State Hospital, Giseler Mevki Nehir Kent, Tem Uzeri Adapazari Cikisi, Sakarya, Turkey.

Arachnoid cysts (AC) located within the interhemispheric fissure are rare, frequently associated with agenesis or hypogenesis of the corpus callosum. The optimal method for surgical treatment is under debate. In this study, we retrospectively reviewed the clinical results of seven infants (five males, two females; mean age, 5.1 months) with large interhemispheric AC who underwent cystoperitoneal shunting (CP) and evaluated the long-term efficacy in terms of clinical data, psychomotor development and neuroimaging. All patients were symptomatic and operated on before they reached 1 year of age. In three patients, additional ventricular catheters were inserted due to concomitant hydrocephalus. The additional catheters were joined with the cyst catheters and the peritoneal catheters with Y-shaped connectors in the same session. The patients were followed up for an average of 57 months (range 24-120 months). The clinical and developmental outcome was good in most patients with complete resolution of symptoms and signs. The developmental outcome scale, which included cognitive and psychomotor development, was "good" (normal) or "fair" (near normal) for six of seven patients. Radiologically, the cyst was completely or nearly totally resolved in five patients, and partially resolved in two. In these symptomatic patients with interhemispheric AC, CP shunting provided favorable treatment outcomes with complete or near-total resolution of symptoms and reduction in cyst size or disappearance of the cyst.

Cabergoline versus bromocriptine for symptomatic treatment of premenstrual mastalgia: a randomised, open-label study.

Eur J Obstet Gynecol Reprod Biol 2010 Jun 4;150(2):203-6. Epub 2010 Mar 4.

Cerrahpasa Medical Faculty, Istanbul University, Istanbul, Turkey.

Objective: To compare the effectiveness and side effects of cabergoline with bromocriptine for the symptomatic treatment of cyclic mastalgia as a part of the premenstrual syndrome.

Study Design: 140 women with premenstrual mastalgia were enrolled in this randomised, open-label trial. Two groups were created (bromocriptine and cabergoline) and consisted of 61 and 67 patients respectively at the end of trial. Bromocriptine was administered 5 mg daily during second half of the menstrual cycle. Cabergoline was administered 0.5 mg weekly during the second half of the cycle. Relief of pain was evaluated using a visual analog scale (VAS). The mean percentage decrease in score for all patients in each group was calculated. A 50% or greater decrease at the end of the third month from the basal VAS score was accepted as a positive response to drug therapy. Data regarding side effects were collected systematically with review of a symptom diary.

Results: The positive response rates to treatment were similar (bromocriptine 66.6% and cabergoline 68.4%). The pain reduction rates for each month were also similar. Moreover, the pain reduction rate was maximum in the second month of treatment for both groups. Vomiting (28%), nausea (39%) and headaches (23%) recorded in the bromocriptine group were significantly more frequent than vomiting (4.5%), nausea (20.9%) and headache (6%) recorded in the cabergoline group (p=0.023, p=0.001, p=0.006 respectively). A difference in the rate of dizziness was not statistically significant (26.4% vs. 14.9%). There was no correlation between the baseline breast pain score and prolactin level but post-treatment pain reduction was well correlated with prolactin level.

Conclusions: Cabergoline is as effective as bromocriptine for the treatment of cyclic mastalgia but has minimal side effects compared to bromocriptine.

The incidence of placental abnormalities, maternal and cord plasma malondialdehyde and vascular endothelial growth factor levels in women with gestational diabetes mellitus and nondiabetic controls.

Gynecol Obstet Invest 2008 14;65(4):227-32. Epub 2008 Jan 14.

Department of Obstetrics and Gynecology, Cerrahpasa Medical Faculty, University of Istanbul, Istanbul, Turkey.

Background/aims: To evaluate the incidence of placental abnormalities, cord plasma erythropoietin (EPO) levels and nucleated red blood cell (NRBC) counts, maternal and cord plasma malondialdehyde (MDA) and vascular endothelial growth factor (VEGF) levels in women with gestational diabetes mellitus (GDM) and nondiabetic controls.

Methods: Twenty-two women with GDM, diagnosed according to the current criteria of the American Diabetes Association, were compared with 22 controls. Maternal and cord blood and placental samples were obtained from all pregnant women. Cord plasma EPO levels and NRBC counts, maternal and cord plasma MDA and VEGF levels were determined. Placental tissues were examined histologically.

Results: Maternal and cord plasma levels of MDA and cord plasma EPO levels and NRBC counts were significantly higher in GDM pregnancies (p < 0.01). The presence of villous immaturity, chorangiosis and ischemia were significantly increased in the placentas of women with GDM (p < 0.05). The maternal and cord plasma levels of MDA increased (p = 0.007 and p = 0.001, respectively), whereas VEGF decreased (p = 0.046 and p = 0.001, respectively) with the presence of villous immaturity.

Conclusion: The complex process of villous development and maturity might be influenced by the maternal and fetal oxidative and angiogenetic milieu. The placenta that shows abnormalities in angiogenesis and maturation may lead to fetal hypoxia and compromise.

Placental stem cell markers in pre-eclampsia.

Int J Gynaecol Obstet 2008 Mar 28;100(3):228-33. Epub 2007 Nov 28.

Department of Obstetrics and Gynecology, Cerrahpasa Medical Faculty, Istanbul University, Istanbul, Turkey.

Objective: To investigate the placental CD34, CD44, and leukemia inhibitory factor (LIF) levels in normotensive and pre-eclamptic women.

Method: The study population consisted of 21 women with pre-eclampsia. Twenty normotensive pregnant women served as controls and were matched to pre-eclamptic patients by gestational age at delivery. Decidual samples obtained from the central part of the placenta were stored at -70 degrees C until analysis. CD44 and LIF were quantified in homogenates by enzyme-linked immunosorbent assay (ELISA), while CD34 was quantified by flow cytometry.

Results: The pre-eclamptic and normotensive groups were well matched. There were no significant differences in age, parity, weight, and gestational age at birth between the groups (P>0.05). The mean placental levels of CD34 (6.55+/-2.48 vs 3.16+/-1.23), CD44 (385.24+/-178.85 vs 157.75+/-31.73, and LIF (140+/-51.11 vs 96.25+/-31.62) were significantly higher in pre-eclamptic compared with normotensive women, respectively (P<0.05).

Conclusion: Higher levels of CD34, CD44, and LIF were found in the placentas of pre-eclamptic compared with normotensive women.

A comparison of oral and vaginal misoprostol for induction of labor.

Eur J Obstet Gynecol Reprod Biol 2005 Sep;122(1):57-60

Department of Obstetrics and Gynecology, Cerrahpasa Medical Faculty, University of Istanbul, 7-8 Kisim, L1-D, D:30, 34750 Ataköy, Istanbul, Turkey.

Objective: The aim of the study is to compare the efficacy and safety of oral (100 microg) and vaginal (50 microg) misoprostol for labor induction.

Study Design: Ninety-nine patients with indications for labor induction randomly received 100 microg oral misoprostol every 4 h or 50 microg vaginal misoprostol every 4 h, using maximum six doses. Mean induction to delivery interval, mode of delivery, rates of tachysystole, hypertonus and hyperstimulation syndrome, oxytocin use, number of doses used, failed induction rate and neonatal outcomes were compared for the two groups.

Results: Mean dose of misoprostol used for oral and vaginal misoprostol groups were 2.17+/-1.35 and 1.91+/-0.94, respectively (p=0.65). There were two failed inductions in the oral (4%) and one failed induction (2.5%) in the vaginal group after a total of six doses of misoprostol (p=0.58). There was no significant difference for the mean induction to delivery interval, to the beginning of active phase interval, active phase duration, second stage duration and the number of women who received oxytocin for induction or augmentation between the two groups (p>0.05). There were also no significant differences for intrapartum complications and neonatal outcomes between the oral and vaginal misoprostol groups (p>0.05).

Conclusion: Our findings indicate that, in a closely supervised hospital setting with adequate monitoring, 100 microg oral misoprostol has the potential to induce labor as safely and effectively as its 50 microg vaginal analogue. As oral use of the drug is easier for both the patient and the doctor, oral misoprostol will probably be more preferable than the vaginal route.

Plasma malondialdehyde, superoxide dismutase, sE-selectin, fibronectin, endothelin-1 and nitric oxide levels in women with preeclampsia.

Eur J Obstet Gynecol Reprod Biol 2004 Mar;113(1):21-5

Department of Biochemistry, Cerrahpasa Medical Faculty, University of Istanbul, Istanbul, Turkey.

Objective: The purpose of this study was to determine plasma malondialdehyde (MDA), superoxide dismutase (SOD), soluble E-selectin (sE-selectin), fibronectin, endothelin-1 (ET-1) and nitric oxide (NO) levels in women with preeclampsia and to find out the relations of diastolic blood pressure with these variables.

Study Design: We performed a case-control study consisting of randomly selected 34 healthy pregnant women and 35 patients diagnosed as preeclampsia. Lipoperoxidation was ascertained by the formation of MDA. SOD activity was determined by the method of Sun et al. Plasma concentration of NO was estimated using colorimetric assay. Plasma ET-1 and sE-selectin were measured by enzyme-linked immunosorbent assay (ELISA). A nephelometric method for fibronectin quantitation was used.

Results: The mean plasma level of MDA was significantly higher and SOD was significantly lower in preeclamptic pregnancies (P<0.001). Plasma concentrations of fibronectin, sE-selectin and ET-1 were significantly increased, whereas NO was significantly decreased in women with preeclampsia than normotensive women (P<0.001).

Conclusion: Increased plasma levels of MDA, fibronectin, sE-selectin, ET-1, and decreased plasma levels of NO and SOD in preeclamptic patients suggest that poorly perfused fetoplacental unit is the origin of oxygen free radicals and lipid peroxides.

Maternal plasma levels of cytokines in normal and preeclamptic pregnancies and their relationship with diastolic blood pressure and fibronectin levels.

Acta Obstet Gynecol Scand 2003 Sep;82(9):797-802

Department of Obstetrics and Gynecology, Cerrahpasa Medical Faculty, University of Istanbul, Istanbul, Turkey.

Background: To determine the plasma concentrations of placental growth factor (PLGF), vascular endothelial growth factor (VEGF), transforming growth factor-beta1 (TGF-beta1), soluble tumor necrosis factor alpha receptor (sTNFp55), interleukin-2 receptor (IL-2R), and interleukins 6 and 10 (IL-6, IL-10) in normotensive and preeclamptic women, and to evaluate the correlations between these cytokines and the diastolic blood pressure and fibronectin levels.

Methods: A prospective case-control study. Thirty-five women with preeclampsia were compared with 34 healthy women with uncomplicated pregnancies. Peripheral venous blood samples were obtained and plasma levels of PLGF, VEGF, TGF-beta1, sTNFp55, IL-2R, IL-6 and IL-10 were measured by an enzyme-linked immunoassay and fibronectin by a radial immundiffusion technic.

Results: In preeclampsia PLGF and VEGF levels were significantly lower, and TGF-beta1, sTNFp55, IL-2R, IL-6 and IL-10 levels were significantly higher than in normotensive pregnancy (p < 0.001). The plasma levels of PLGF and VEGF significantly decreased, whereas TGF-beta1, sTNFp55, IL-2R, IL-6 and IL-10 levels significantly increased with the increments in diastolic blood pressure and fibronectin levels (p < 0.001).

Conclusions: Altered concentrations of various cytokines might explain the shallow placentation and endothelial cell dysfunction described in preeclampsia. The clinical severity of preeclampsia seems to correlate with the severity of the cytokine abnormalities.

Prenatal diagnosis of arthrogryposis multiplex congenita with increased nuchal translucency but without any underlying fetal neurogenic or myogenic pathology.

Fetal Diagn Ther 2002 Jan-Feb;17(1):29-33

Department of Obstetrics and Gynaecology, Cerrahpasa Medical Faculty, University of Istanbul, Turkey.

Arthrogryposis multiplex congenita is a general term for congenital multiple joint contractures, the aetiology of which is variable. Prenatal diagnosis is usually based on the detection of diminished fetal movements and joint contractures on ultrasound. There are also reports of early diagnosis of arthrogryposis in the first and early second trimester by detection of subcutaneous oedema. We report another case of arthrogryposis multiplex congenita with increased nuchal translucency and scoliosis diagnosed by ultrasonography at 15 weeks of gestation. The pregnancy was terminated at the request of the parents. Post-mortem examination revealed that it was not associated with fetal myopathy or neuropathy. Multiple joint contractures with increased nuchal translucency without any underlying fetal neurogenic and myogenic pathology may be a distinct form of arthrogryposis multiplex congenita.
