Mehmet Erdem; Ahmet Erdem; Rifat Gursoy; Kutay Biberoglu

AbstractPurpose: To compare basal and clomiphene citrate (CC) induced follicle-stimulating hormone (FSH), estradiol (E2), and inhibin B levels with ultrasound indices of ovarian reserve in infertile women and to test the prognostic value of these tests on response to ovarian stimulation in in vitro fertilization (IVF). Methods: Fifty-six patients had basal and CC induced serum hormone levels and ultrasound measured mean ovarian volume (MOV) and mean antral follicle counts (MFC). Thirty-two patients were then appropriately selected to have a total of 41 cycles of IVF/ICSI treatment. Results: Women with diminished ovarian reserve had lower MOV, MFC, day 3 and day 10 inhibin B levels (p< 0.001). Only basal and CC induced FSH and inhibin B correlated with MOV and MFC. Poor responders in IVF/ICSI had higher basal FSH (p< 0.05), lower basal and induced inhibin B levels (p< 0.05), and lower MOV and MFC (p< 0.01) than normal responders. Ovarian volume alone was better than age and basal hormones in predicting poor ovarian response, while abnormal CC test was the only independent significant factor in predicting ovarian response. However, age was the only independent predictor of pregnancy in IVF as compared to hormonal and ultrasound indices of ovarian reserve. Conclusion: CC test and ovarian volume are better than other hormonal and sonographic tests in predicting the response to ovarian stimulation in IVF cycles.

OBJECTIVE To document the relationship between smooth endoplasmic reticulum (SER) aggregations and recurrent fetal anomalies. DESIGN Case report. SETTING Private IVF center. PATIENT(S) A 28-year-old woman with an 11-year history of primary infertility. INTERVENTION(S) Three consecutive cycles of intracytoplasmic sperm injection (ICSI) in the same patient. MAIN OUTCOME MEASURE(S) Clinical pregnancy, live birth, fetal anomaly. RESULT(S) In three consecutive ICSI cycles, a total of 59 MII oocytes were retreived in the same patient, all displaying SER aggregations. The fertilization rate per cycle was 80%, 50%, and 42%, respectively. A total of 12 embryos were transferred in three ICSI cycles, of which 11 were grade 1 embryos. Two of the three cycles ended up with clinical ongoing pregnancies but with multiple fetal anomalies. CONCLUSION(S) This is the first case reported with SER aggregations in all retrieved oocytes in three consecutive ICSI cycles. The repetetive multiple fetal anomalies possibly related to oocyte dysmorphism are of concern.

Our objective was to compare the relationship between age ,basal follicle stimulating hormone (FSH) level and ultrasound-measured mean ovarian volume (MOV) and mean antral follicle counts (MFC) in a group of infertile and fertile women between the ages of 35 and 45 years. Menstrual cycle day 3 serum FSH ,MOV and MFC were analyzed in 62 infertile and 53 fertile women. Basal FSH and MFC did not differ between infertile and fertile women ,whereas MOV was significantly smaller in infertile women (p < 0.05). In the infertile group ,there was a negative correlation between MOV and age (ρ = -0.389, p < 0.05) ,between MOV and basal FSH (ρ = 0.495 ,p < 0.01) ,and between MFC and age (ρ = -0.553 ,p < 0.01). In the fertile group ,there was a strong negative correlation between MOV and basal FSH (ρ = -0.631 ,p < 0.01) ,and between MFC and basal FSH (ρ = -0.710 ,p < 0.01). Mean basal FSH ,MOV and MFC did not differ between subgroups of patients with different causes of infertility. In the infertile group ,patients with small ovaries of volume less than 1.8 cm3 (mean volume -1 SD) had higher mean basal FSH (p < 0.05) and lower MFC (p < 0.01) levels than patients with normal ovarian volume. In conclusion ,transvaginal ultrasound (TVU) indices and indirect hormonal parameters of ovarian reserve were similar in infertile and fertile women aged between 35 and 45 years. It is suggested that ,in infertile women above 35 years of age ,TVU rather than hormonal parameters be preferred ,based on our data showing a stronger association between age and TVU indices of ovarian reserve than between age and increase in basal FSH level. Thus ,TVU assessment of ovarian volume and antral follicle counts is a practical and cost-effective ,if not better ,technique for ovarian reserve testing.

The objective of this study is to evaluate the performance of clomiphene citrate (CC) challenge test to predict diminished ovarian reserve before controlled ovarian hyperstimulation for intracytoplasmic sperm injection (ICSI). The 198 women who underwent the CC challenge test fulfilled the following criteria; over 35 years of age, removal of one ovary or previous ovarian surgery, the presence of ovarian endometrioma or previous poor response to ovarian hyperstimulation. Of the patients tested, 141 were found to have a normal CC challenge test while 57 had an abnormal result. The cancellation rate of the cycle with a poor response was significantly higher in women with an abnormal test (36.8%) than in those with a normal test (19.8%) (P < 0.05). The sensitivity of CC test for cycle cancellation was found to be 43% with a specificity of 76%, positive and negative predictive values of 37 and 80%, respectively. The estradiol values on hCG day, the number of retrieved oocytes and metaphase II oocytes and the rate of transfer cycles were significantly lower in females with an abnormal test. Women with normal test results had higher pregnancy rates per embryo transfer than those with abnormal test results (21.5 vs. 13.3%) and the predictive value of an abnormal test for failing to conceive was 93% (53/57) with a sensitivity of 31%, specificity of 84% and negative predictive value of 15.6%. Of 57 women with an abnormal test result, 25 (43.8%) were abnormal due only to an elevated day 10 or 11 value of FSH, which could not be detected using only basal FSH screening. In this group, the cancellation rate (48 vs. 19.8%, P < 0.01), the rate of transfer cycles (48 vs. 72.3%, P < 0.05) and the mean number of retrieved oocytes (4.9 +/- 2.5 vs. 6.4 +/- 3.1, P < 0.01) were all significantly different from normal test group. Although the rate of pregnancies per started cycle (8 vs. 15.6%) did not show a statistically significant difference, this is most probably due to the low number of patients. In conclusion, an abnormal CC challenge test is a good predictor of diminished ovarian reserve and it is better than a basal FSH concentration on day 3. It provides valuable information for both patients as to their chances of achieving a pregnancy and also for the medical team deciding on options for stimulation protocols.

Abstract Objective: Intrahepatic cholestasis of pregnancy (ICP) is the most common pregnancy-specific liver disease, is characterized by pruritus, abnormal liver function and elevated serum bile acid levels. The main cause of ICP has not yet been identified. We aimed to provide a new perspective to the pathogenesis of by investigating the possible association of circulating interleukin-17 (IL-17) that is a recently discovered proinflammatory cytokine levels with ICP. Materials and methods: In this controlled cross-sectional study, maternal venous blood samples were obtained from 33 consecutive pregnant women with ICP (15 with mild and 18 with severe forms of the disease) and 25 healthy women with uncomplicated pregnancies (as the control group) and IL-17 levels were compared among the groups. Results: Although serum IL-17 levels were significantly higher in the severe ICP group than in the control group (p = 0.022), there were no significant differences between the mild and severe ICP groups or between the control and mild ICP groups. Conclusion: Explaining the mechanisms of hepatocyte injury might contribute to the existing therapeutic strategies for treating cholestatic diseases. Changes in IL-17 levels may shed light on the pathogenesis of ICP.

Abstract Objective: To evaluate the circulating soluble fms-like tyrosine kinase 1 (sFlt1), placental growth factor (PlGF) and vascular endothelial growth factor (VEGF) levels in women with abnormal placentation and to compare the data with the results of women with normal pregnancy. Material and methods: Serum biomarkers of angiogenesis and maternal and perinatal characteristics of 68 pregnant women, all in the third trimester, who were diagnosed to have vaginal bleeding due to complete placenta previa with and without concomitant placenta accreta, increta and percreta as the study group and 30 pregnant women without any placentation abnormality who eventually delivered at  ≥37 weeks of gestational age as the control group were evaluated. Results: There was no statistical difference in the maternal serum values of sFlt1, PlGF, sFlt1/PlGF ratio and VEGF in groups with placental abnormality as compared to controls. Not even a single case of preeclampsia and intrauterine fetal growth restriction was encountered in the study group. Conclusion: We demonstrated that regardless of the localization and the degree of the myometrial invasion of the placenta in the uterus, the circulatory biomarkers of angiogenesis and vascularization were comparable.

Abstract In this study, our objective was to determine the effect of adding estradiol hemihydrate (E2) to progestin (P) for luteal phase support on pregnancy outcome in in vitro fertilization (IVF) cycles with poor response to gonadotropins. Ninety-five women with poor ovarian response who underwent controlled ovarian hyperstimulation (COH) with gonadotropin releasing hormone (GnRH) agonist or GnRH antagonist plus gonadotropin protocol for IVF were prospectively randomized into three groups of luteal phase support after oocyte retrieval. Group 1 (n = 33) received only intravaginal progesterone gel (Crinone 8% gel). Group 2 (n = 27) and Group 3 (n = 35) received intravaginal progesterone plus oral 2 and 6 mg estradiol hemihydrate, respectively. Main outcome measures were overall and clinical pregnancy rates (PRs) per patient. Serum LH, E2 and P levels at 7th and 14th days of luteal phase were also measured. Overall and clinical PRs were significantly higher in 2 mg E2 + P than P-only group (44% versus 18% and 37% versus 12.1%, respectively). There were no statistically significant differences between 6 mg E2 + P versus P-only and 2 mg E2 + P versus 6 mg E2 + P groups regarding PRs. Addition of 2 mg/day E2 in addition to P for luteal support significantly increase overall and clinical PRs in cycles with poor response to gonadotropins after IVF.

Nuray Bozkurt; Mertihan Kurdoglu; Zehra Kurdoglu; Fatma Kutlusoy; Kutay Biberoglu

Objective. To determine the advantages and disadvantages of the use of diclofenac sodium instead of meperidine for postcesarean section pain control. Methods. A total of 130 patients who had undergone cesarean section at the Department of Obstetrics and Gynecology of Gazi University Hospital were prospectively randomised to receive one of two postoperative pain control regimens. The first group of patients received intramuscular diclofenac sodium at a dose of 2×75 mg and additional breakthrough meperidine was given intramuscularly at 50 mg dosages each time, if necessary. Patients in the second group received only 6×50 mg meperidine. Results. Twenty-seven of the 65 patients in the diclofenac group complained of unrelieved pain within the subsequent 24 h postoperatively. Patients receiving diclofenac alone or a combination of diclofenac + meperidine were less sedated and the time to the first passing of flatus was shorter than that in the patients treated with only meperidine. Conclusions. Diclofenac alone was safe and effective for the majority of the patients and it decreased the opioid requirements in the remaining patients.
