Gestational Outcomes of Pregnant Women with Unilateral Congenital Renal Agenesis.

ObjectiveWe evaluated if there were more adverse gestational outcomes of pregnant women with unilateral congenital renal agenesis (UCRA). Study design: This single center retrospective case-control study compared maternal complications and neonatal outcomes from 25 women with UCRA to the outcomes of 125 women with two kidneys. Results: UCRA women had lower gestational weeks at birth and higher rates of preterm delivery (p = 0.004 and <0.001; respectively). Mothers had higher rates of preeclampsia and newborns with congenital anomalies and neonatal intensive care unit (NICU) admission (p = 0.009, 0.042, and 0.039; respectively). Unadjusted odds ratios were significantly higher for preterm delivery and for any APGAR score of <7 at the first 10 min and preeclampsia [OR (95% CI):13.5 (4.66-39.05), 31 (3.44-279.32) and 5.76 (1.33-24.84), respectively]. Conclusion: Maternal UCRA is a risk factor for less optimal obstetric and neonatal outcomes.

Chorionic villus sampling experience of a reference perinatal medicine center.

AIM: To share the chorionic villus sampling (CVS) experience of a single surgeon in our institution. METHODS: This retrospective study consists of CVS cases performed between 2000 and 2018. A total of 66 types of indications were classified under two main categories, the screening group (SG) and the inherited disease group (IDG). The SG and IDG were compared in terms of clinical characteristics of the patients, Beksaç obstetrics index (BOI), timing of CVS in terms of gestational week, and complications and termination of pregnancy (TOP) rate. RESULTS: CVS was performed at 656 women, 69 and 587 of whom were included in the SG and IDG, respectively. CVS indications of the SG were determined as advanced maternal age, high risk in combined test, fetal anomaly suspicion in ultrasonography, and increased nuchal translucency in 23, 23, 14 and 9 cases, respectively. On the other hand, CVS indications of the IDG were hereditary disorders related to hematological, muscular, and metabolic systems for 233, 179, and 116 cases, respectively. Furthermore, 32 patients had a single-gene disorder and 14 had a neurodegenerative disease. According to the results of CVS, 359 fetuses were found to be normal (54.73%), while 205 (31.25%) and 92 (14.02%) fetuses were found to be disorder-positive or carriers, respectively. Two hundred pregnant women accepted TOP. Eight (1.2%) pregnancies ended with abortion after CVS. Statistically significant differences were observed in BOI and TOP rate between SG and IDG (p: 0.042 and 0.013). CONCLUSION: Hereditary disorders were the most common CVS indications and the acceptance of TOP was significantly higher in this group.

Granulomatosis with polyangiitis and pregnancy: Anti-neutrophil cytoplasmic antibody, placental inflammation, chorangiosis and pre-eclampsia.

Granulomatosis with polyangiitis (GPA) is a rare necrotizing autoimmune disease involving small vessel vasculitis. Pregnancies with GPA have increased rates of obstetric complications including pre-eclampsia. Differential diagnosis of GPA flares up and pre-eclampsia may be difficult and necessitates careful clinical practice. A 26-year-old pregnant woman with GPA was referred for hypertension. The absence of GPA signs and symptoms, negative anti-neutrophil cytoplasmic antibody titer and the presence of clinical and laboratory findings supported the diagnosis of pre-eclampsia rather than a GPA flare-up. The newborn was delivered via cesarean section at the 30th gestational week due to severe superimposed pre-eclampsia. Pathological examination of the placenta demonstrated the presence of chorangiosis and focal placental infarcts. GPA should be considered as a risk factor in pregnancy and requires careful clinical management to have good gestational outcome. Physicians should be vigilant regarding gestational diabetes and pre-eclampsia as well as GPA flare-up.

Fetal Cell Microchimerism; Normal and Immunocompromised Gestations in Mice.

Objective: To compare fetal cell microchimerism in normal and immunocompromised gestations. Materials and methods: The study consists of two groups of mature female mice. In the control group and the immunocompromised study group, 5 mg of saline and cyclosporine were injected intraperitoneally, respectively. In the second step, all female mice were mated with "Actine-Luc (+) green fluorescent protein (GFP)" transgenic male mice. Immunohistochemical studies (ALPL-antiluciferase, cytokeratin-antiluciferase, and CD 105-antiluciferase) were carried out on maternal liver, skin, and lung tissues at 6-7th and 14-15th gestational days, and postpartum 3-4th, 12th, and 18-24 months. Results: GFP (+) cells were detected in maternal liver and skin but not in lung tissue. Liver was the most affected tissue. GFP was found to be more intense in the immunocompromised group. Conclusion: Fetal microchimerism was demonstrated in maternal liver and skin and found to be more intensive in the immunocompromised group.

Characteristics of obstetric admissions to intensive care unit: APACHE II, SOFA and the Glasgow Coma Scale.

Objective To evaluate the characteristics of obstetric admissions to an intensive care unit (ICU) and assess the utility of Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA) and the Glasgow Coma Scale (GCS). Methods This study is consisted of 160 patients admitted to an ICU during the antenatal period or within 7 days at the postpartum period. Clinical characteristics and ICU scores were evaluated. Results The rate of admission to the ICU was 7.8/1000 deliveries. Four cases ended with maternal mortality (2.5%). The most common hospitalization indications were hypertensive disorders of pregnancy, cardiovascular disorders and obstetric hemorrhage, at 40 (25%), 34 (21.2%), and 31 (19.3%) cases, respectively. The receiver operating characteristics (ROC) curve analysis for prediction of maternal mortality revealed area under curve (AUC) values as 0.971 both for APACHE II and predicted mortality rate (PMR), and 24.5 and 47.1 were determined as the cut-offs with sensitivities of 100%. AUCs were also 0.901 and 0.929 for the initial and worst SOFA score, respectively. The cut-off value for the initial and worst SOFA score was 3.5, with a sensitivity of 100%, and was 10 with a specificity of 98.9%, respectively. Conclusion APACHE II and PMR overpredict maternal mortality, but those higher scores predict maternal mortality. Higher SOFA scores are related with maternal mortalities with high specificity.

Clinical analyses of 383 cases with maternal cardiac diseases.

AIM: To evaluate the pregnancy outcomes of women with heart disease. MATERIALS AND METHODS: In this retrospective study, 383 pregnant women with cardiac diseases were examined. The cases were classified according to the World Health Organization (WHO) classification. The distribution of the cases according to class, congenital heart diseases, mean birthweight, mean gestational week at delivery, type of delivery [cesarean section (CS) or vaginal delivery], and cardivascular events (during pregnancy and puerperium) were evaluated. RESULTS: Of the 383 patients, 25 were in Class I; 39, Class II; 255, Class II or III; 31, Class III; and 33, Class IV cardiac diseases. The neonatal birth weights were significantly lower in Class III than in Classes II, and II or III. The preterm delivery rate was higher in Class III than in the other classes. Delivery was performed by CS due to cardiac indications in the high-risk classes, however, only obstetric indications were considered in the low-risk classes. Only one case of maternal death occurred during the postpartum period, in a patient with Eisenmenger's syndrome. DISCUSSION: Cardiovascular diseases are an important cause of mortality and morbidity in pregnancy. The adverse impact of cardiovascular disorders on pregnancy outcomes should be the main concern during the management of these women.

Comparison of different types of twin pregnancies in terms of obstetric and perinatal outcomes: association of vanished twins with methylenetetrahydrofolate reductase (MTHFR) polymorphism(s).

PURPOSE: Vanished twin (VT) has been associated with poor perinatal outcomes. Our research aimed to investigate the outcomes of pregnancies with vanished twin and its possible association with methylenetetrahydrofolate reductase (MTHFR) polymorphisms. METHODS: This study consisted of 30 of 38 VT pregnancies (group 1, VT group), 109 singletons (group 2), 70 spontaneous twins (group 3), and 101 in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) twins (group 4). RESULTS: Most patients in group 1 (28/30) were tested for MTHFR genes (C677T or A1298C polymorphisms). Eight of the 38 pregnancies with VT (21.1%) resulted in miscarriage. The prevalence of "2 or more pregnancy losses" in the "obstetric history" in group 1 was higher (23.3%) than those in the other groups (p = 0.007, χ2 = 17.8). The allelic frequencies of MTHFR 677 and MTHFR 1298 in group 1 were 0.268 and 0.429, respectively (higher than those in healthy population). The median birthweights in groups 1, 2, 3, and 4 were 2940, 3200, 2300, and 2095 g, respectively. The prevalence of respiratory distress syndrome was significantly higher in the IVF/ICSI twin pregnancy group (p < 0.001, χ2 = 21.2). Early pregnancy loss and the presence of "2 or more miscarriages" in the obstetric history of pregnancies with VT were more frequent. CONCLUSION: The coincidence of VT and MTHFR polymorphisms might play an incidental or factual role in this connection.

Are Congenital Urinary Tract Abnormalities Linked to Maternal Methylenetetrahydrofolate Reductase Polymorphisms in Fetuses of Intentionally Terminated Pregnancies with Oligo- or Anhydramnios ?

OBJECTIVE: We aimed to evaluate fetuses of terminated pregnancies with oligo-or anhydramnios (OAH) to further investigate the association between maternal methylenetetrahydrofolate reductase (MTHFR) polymorphisms and fetal urinary tract malformations. MATERIALS AND METHODS: This retrospective study included 16 pregnancies with OAH (with normal fetal karyotype) that were intentionally terminated before 22nd gestational week. Fetal autopsy was performed in all cases. We evaluated cases for presence of DNA methylation pathway-related gene polymorphisms. RESULTS: We demonstrated that renal abnormalities and disorders exist in 75% of the cases. Pulmonary system anomalies and single umbilical artery were the most frequently observed associated abnormalities. Polymorphisms with known reduced MTHFR activity were found in 81.8% (9/11) of the cases.Association between urinary system abnormalities and polymorphisms with known reduced MTHFR activity was observed in 88.8% (8/9) of the cases. CONCLUSION: Physicians should keep in mind that polymorphisms with known reduced MTHFR activity may be associated with urinary tract abnormalities and OAH.

Myomectomy during cesarean section and adhesion formation as a long-term postoperative complication.

OBJECTIVES: We aimed to evaluate the incidence and features of postoperative adhesion related complications occurring following myolysis or myomectomy performed during cesarean section (C/S). METHODS: This cross-sectional study consists of four groups of patients who underwent C/S: group I; myolysis is performed by electric cauterization for small superficial fibroids less than 2 cm. (n: 21), group II; myomectomy is performed for pedunculated fibroids (n: 18), group III; myomectomy is performed for intramural/subserous fibroids less than 5 cm. (n: 23), group IV control group (n: 19) who did not go through myomectomy Repeat C/S is performed to study subjects within 1-5 years. All cases are evaluated in terms of mild to moderate adhesions between omentum and uterus, mild to moderate adnexial area adhesions, mild to moderate incision area adhesions and surgical difficulty due to severe adhesions. RESULTS: The incidence of adhesions of omentum and uterus (p= 0.278), mild to moderate adnexial area adhesions (p = 0.831), mild to moderate incision area adhesions (p= 0.804) were similar between the intervention groups (group I, II, and III) and the controls (group IV). CONCLUSION: Cesarean myomectomy is a safe procedure and can be performed without significant postoperative adhesion formation.

Interactions of actinomyces -like organisms with host cells: light microscopic examination.

OBJECTIVE: To determine the interactions of Actinomyces-like organisms (ALOs) with host cells, including vaginal epithelial cells, polymorphonuclear leukocytes (PMNLs) and erythrocytes, using Pap smear microscopy and based on their light microscopic appearances. STUDY DESIGN: Cervicovaginal samples obtained from 200 patients were examined by both Pap smear microscopy and anaerobic culturing. Since the results obtained by these methods were not concordant for diagnosis of genital Actinomyces, the results of Pap smear microscopy were used as a reference, and the smears with ALOs were carefully screened with regard to interactions of ALOs with host cells. RESULTS: ALOs were detected as attached to vaginal epithelial cells, PMNLs and erythrocytes via their filament-like structures. At some attachment sites, the epithelial cell membrane and filaments of ALOs were almost fused with each other. A group of PMNLs surrounded the ALOs. However, ALOs were observed to form colonies to evade phagocytosis by PMNLs. At the connection points between erythrocytes and ALOs, the findings of interest were the changes in the shapes of the erythrocytes and filament-like structures of the ALOs on the erythrocyte membrane. CONCLUSIONS: The adhesiveness of ALOs can be observed in routine Papanicolaou-stained cervicovaginal smears at light microscopic level.

Prenatal diagnosis of hemoglobinopathies in Hacettepe University, Turkey.

Between 1983 and 2008, prenatal diagnostic procedures for identifying hemoglobinopathies were performed in 947 at-risk fetuses. Seventy-six percent of the fetuses were at risk for ß-thalassemia major and 16% for sickle cell anemia; only a small percentage (7%) were at risk for compound heterozygosity of ß-thalassemia and an abnormal hemoglobin of the ß chain. The results of the study showed that ß gene mutations in hemoglobinopathies have a very broad spectrum. Seven hundred and thirty of the 947 fetuses examined using the DNA technique showed 88 different combinations of 27 different mutations. Although the number of fetuses evaluated was far below the desired target, the termination of 261 affected fetuses provided both psychological and economic relief for the parents and was economically beneficial for the country in the long term.

Severe factor X deficiency in a twin pregnancy.

Factor X deficiency is a rare bleeding disorder inherited in an autosomal recessive fashion. In severe cases with a definitive bleeding phenotype, prophylaxis with prothrombin complex concentrate appears to prevent bleeding very effectively. Management of factor X-deficient pregnant patients continues to be a challenge. We present a new case of successful twin pregnancy in a severe factor X-deficient patient.

Effect of anti-epileptic drugs on first trimester screening test results.

OBJECTIVE: To evaluate first trimester screening test parameters in epileptic patients using anti-epileptic drugs. MATERIALS AND METHODS: We retrospectively evaluated first trimester screening test results of 23 epileptic pregnant women using anti-epileptic drugs with a control group consisting of 92 healthy pregnancies. The anti-epileptic drugs used in this study were carbamazepine, levatiracetam, valproic acid and lamotrigine. Single drug or multi-drug regimens were used according to the clinical conditions. Patients with any known chronic or acute disease and drug usage were excluded from the study. Comparisons were performed via Mann-Whitney U test. RESULTS: First trimester screening test biochemical markers were compared and maternal serum PAPP-A MoM values were found to be similar in study and control groups while ß-hCG MoM values were significantly higher in pregnancies using epileptic drugs (p: 0,737 and p < 0.001, respectively). CONCLUSION: Biochemical first trimester screening test results may be affected by anti-epileptic drug usage, which may lead to misinterpretation of the risk level. Thus, validation of MoM values should be necessary in order to obtain optimal results.

Neonatal outcomes of early- and late-onset preeclampsia.

BACKGROUND: The aim of the current study was to demonstrate the neonatal outcomes of infants born to mothers with early-onset preeclampsia (EP) and late-onset preeclampsia (LP), and compare the neonatal outcomes before and after 34 weeks of gestation in EP group. METHODS: In this retrospective study, we evaluated preeclamptic mother and child pairs who were followedup at Hacettepe University Hospital between the years 2010 and 2017. The pregnant women were classified as having EP if diagnosed before 34 weeks of gestation (n=91) and LP if diagnosed after 34 weeks of gestation (n=34). The women in the EP group were further divided into subgroups according to the gestational week at birth, including those who gave birth before 34 weeks of gestation (early birth; n=57) and after 34 weeks of gestation (late birth; n=34). Necessary clinical and demographic data were withdrawn from the electronic registry and patient files. RESULTS: Neonates in the EP/late birth subgroup had significantly lower gestational age and birthweight. Small for gestational age (SGA) frequency was higher in the early-onset subgroup born after 34 weeks` gestation compared to the late-onset preeclampsia group (p= 0,016). The incidence of neutropenia was significantly higher in the EP/late birth subgroup than in the LP group (p= 0.002). After correcting for gestational week and birth weight, neutrophil count was still significantly lower in the EP/late birth subgroup (p= 0.002). EP/late birth subgroup and LP group had comparable outcomes regardless of neutrophil count and SGA rate. CONCLUSIONS: Close follow up and postponing delivery in stable and appropriate pregnant women with preeclampsia would be beneficial for neonates.

5-year experience of a tertiary center in major congenital abnormalities in singleton pregnancies.

OBJECTIVE: To demonstrate major congenital abnormalities delivered or terminated at our institution between 2014 and 2018. MATERIALS AND METHODS: Necessary information was retrieved from the registries of the delivery room and electronic database of Hacettepe University Hospital, Ankara. RESULTS: This study was consisted of 307 major congenital anomalies. The incidence of major congenital anomalies was 2.9 per 1,000 live births, while the majority of the cases were related to cardiovascular, central nervous system, and diaphragmatic hernia with 97, 87, and 25 cases at each group, respectively. Rate of termination of pregnancy (TOP) and live birth were 35.1 and 59.2%, respectively. The overall infant mortality rate was 28.9% in cases with live birth, while this rate was highest in cardiovascular system abnormalities and diaphragmatic hernia. Out of 182 newborns, 92.8% admitted to the neonatal intensive care unit after the delivery. Median gestational week at TOP was 21(20). CONCLUSION: We have shown that TOP and infant mortality rates were 35.1 and 28.9%, respectively in pregnancies with fetal malformations. Detailed multidisciplinary counseling must be provided for parents in pregnancies with major congenital abnormalities.

Maternal Mortality: 10 Year Experience of a Tertiary Center in Turkey.

We retrospectively evaluated five maternal mortality cases that occurred in our institution within the last 10 years. Rate of maternal mortality was 24.5 per 100000 live births. Maternal mortality causes were cardiopulmonary failure secondary to veno-occlusive disease, septic shock secondary to osteosarcoma, pulmonary thromboembolism secondary to metastatic breast cancer, septic shock secondary to cholecystitis, and postpartum hemorrhage secondary to Niemann-Pick disease. Four out of five cases were evaluated as indirect maternal mortality cases. Three out of five cases ended up with a healthy newborn, while other cases ended up with abortus and postpartum exitus.

Cord blood delta neutrophil index values of term neonates.

In this study, we aimed to demonstrate cord blood immature granulocyte (IG) count and delta neutrophil index (DNI) values for term neonates. This retrospective study consisted of 126 term newborns born between July 2017 and December 2017. Cord blood samples were collected during delivery and IG count together with DNI values were obtained. `Beckman Coulter DXH800 System Hematology Analyzer` was used for analysis and calculations. The median DNI value was found to be 1.0 (interquantile range(IQR) 0.5-1.8%) and the median gestational age at delivery was 38.4 (IQR 37.6-39.0) weeks. The median birth weight and IG count were 3250 (IQR 2955-3593) g and 66 (IQR 26.5-112.3)/mm3, respectively. In conclusion, we believe that determining the normal laboratory reference values of IG count or DNI, which are important potential diagnostic markers for neonatal sepsis, will contribute to future studies on the diagnosis of neonatal sepsis.

Congenital heart defects: the 10-year experience at a single center.

Objective: We aimed to evaluate congenital heart disease (CHD) cases according to EUROCAT subgroup classification that were diagnosed during the prenatal period in our center.Methods: CHDs that were prenatally diagnosed using ultrasonography and confirmed by fetal echocardiography were reviewed over a 10-year period. Subgroup classification was finalized at the post-partum period in terms of the EUROCAT guide 1.3. Congenital heart defect subtypes and obstetric outcomes (gestational week at delivery, birth weight, gender, extracardiac structural abnormalities, karyotype results if performed) were analyzed.Results: The data of 180 cases with CHD were examined. Left ventricular outflow tract obstruction (LVOT) was the most common CHD subtype (57/180; 31.6%), which included 48, five, and four cases of hypoplastic left heart syndrome (HLHS), coarctation of the aorta, and aortic valve atresia/stenosis, respectively. Eighteen pregnancies were terminated; the most common CHD subtype among patients of terminated pregnancies was hypoplastic left heart syndrome (HLHS) (n = 7, 38.8%). The most common extracardiac malformations were a single umbilical artery, esophageal atresia, and situs inversus in our study group. Eighteen of the 96 (18.75%) neonates with CHD died during the neonatal period. The most common CHD subtype was HLHS (7/18; 38%) among the newborns who died after birth.Conclusion: Prenatal diagnosis of a CHD and subgroup classification is very important for clinical decision making, including prenatal management, recommendations for termination of the pregnancy, postnatal management of the patient, and for early referral to pediatric cardiology and cardiovascular surgery centers.

Perinatal outcomes of twenty-five human immunodeficiency virus-infected pregnant women: Hacettepe University experience

Objective: To evaluate perinatal outcomes in human immunodeficiency virus (HIV) infected pregnant women in Turkey. Material and Methods: Maternal characteristics, pregnancy complications, laboratory findings including HIV load, CD4 cell count, CD4/CD8 ratio, neonatal features and final HIV status of the baby were retrospectively analyzed. Results: The sample included 26 singleton pregnancies, from 25 HIV-infected women. The ethnicities were Turkish (n=18), East European (n=4), Asian (n=2) and African (n=2). The majority (76.9%) was aware of their HIV status before becoming pregnant. Four cases (15.3%) were diagnosed during pregnancy and two (7.8%) at the onset of labor. The results for median HIV viral load, CD4 count, and CD4/CD8 ratio at birth were 20 copies/mL (0-34 587), 577/mm3 (115-977), and 0.7 (0.1-1.9), respectively. The HIV viral load rate was 5.5% in eighteen women taking anti-retroviral treatment. The rates of gestational diabetes mellitus, gestational hypertension, intrauterine growth restriction, and preterm delivery were 3.8%, 3.8%, 7.6%, and 8% (numbers are 1;1;2;2), respectively. The mean gestational week at birth was 38 weeks and mean birthweight is 2972±329 g. Two babies were congenitally infected with HIV (infection rate of 8.3%). There was one needle-related accident during surgery. Conclusion: Timely diagnosis of HIV infection during pregnancy is important for preventing mother to child transmission. HIV infected women may give birth to HIV negative babies with the help of a multidisciplinary team, composed of perinatology, infectious diseases, and pediatrics specialists.

Human papillomavirus infection and autoimmune disorders: a tertiary center experience.

This study aimed to investigate the relationship between HPV and autoimmune disorders. We retrospectively evaluated 62 women who had HPV-DNA positivity in terms of autoimmune disorders (autoimmune antibody positivity, chronic inflammatory diseases and autoimmune diseases). The patients were divided into two groups according to autoimmune disorder positivity (autoimmune positive (n = 30), autoimmune negative (n = 32)) and compared with each other in terms of single and multiple HPV-DNA types, high and low-risk HPV-DNA types, and Pap smear findings. We determined that 48.4% of the HPV-DNA positive patients had autoimmune disorders. We found that 15 of 62 (24.2%) women had more than one type of HPV and HPV type 16 was the dominant type in this study (58.2%). A total of 27.4% of HPV-DNA positive patients had abnormal cytological findings. There was no statistically significant difference between autoimmune groups in terms of the presence of high-risk HPV types, multiple HPV types and abnormal cytological findings (P = 0.531, P = 0.558 and P = 0.234, respectively). The prevalence of autoimmune disorders was high among HPV-DNA positive women. On the other hand, the rate of high-risk HPV type positivity, multiple HPV infections and cytopathological findings were similar between the autoimmune positive and negative groups.
