Impact of bariatric surgery on androgen profile and ovarian volume in obese polycystic ovary syndrome patients with infertility.

Obesity has major adverse effects on reproductive performance and fertility potential especially in women with polycystic ovary syndrome. In this study, we aimed to evaluate the consequences of excess weight reduction by bariatric surgery on androgen levels, and ovarian volume by ultrasonography in obese polycystic ovary patients. This one year Cohort study was carried out in Zagazig university hospitals. The study included 36 infertile women with PCOS and obesity, who underwent bariatric surgery(sleeve gastrectomy or gastric bypass). Patients were evaluated for free and total serum testosterone levels, Sex hormone binding globulin (SHBG), free androgen index (FAI) and also ovarian volume by ultrasound pre-operatively, 6 months and 1 year after surgery. The results showed significant reduction in Body Mass Index, free and total serum testosterone levels and rise in SHBG and regulation of menstrual cycle at 6 and 12 months after operation. Free androgen index and ovarian volume by ultrasound also significantly decreased (p < 0.001) .As a conclusion, Bariatric surgery results in durable loss of weight and restores the normal physiological balance of androgenic milieu and ovarian morphology by ultrasound, in infertile women who have Polycystic ovary syndrome.

Visfatin and SREBP-1c mRNA Expressions and Serum Levels Among Egyptian Women with Polycystic Ovary Syndrome.

Background: Obesity and insulin resistance are common features accompanying polycystic ovary syndrome (PCOS). Aim: To analyze the impact of obesity on the expression of the visfatin and sterol regulatory element-binding protein (SREBP)-1c genes among a group of Egyptian women with PCOS, and to assess their suitability as PCOS biomarkers. Subject and methods: Seventy healthy women (control group) (35 nonobese and 35 obese) and 140 women with PCOS (70 nonobese and 70 obese) were enrolled in this study. The visfatin and SREBP-1c genes' expression analyses were performed via real-time polymerase chain reaction. Serum visfatin and SREBP-1c protein levels were measured with ELISA kits. Results: Among PCOS patients, upregulation of visfatin and SREBP-1c expression was observed. We did not identify significant differences between the obese and nonobese PCOS patients nor between obese and non-obese controls. The mRNA expression levels of both genes were significantly positively correlated with their serum protein levels, as well as with fasting serum insulin levels, homeostatic model assessments of insulin resistance (HOMA-IR), luteinizing hormone (LH) ratios, LH/follicular stimulating hormone ratios, total testosterone, and free androgens. We observed significant negative correlations between visfatin and SREBP-1c expression levels and sex hormone binding globulin levels in all studied groups. Receiver operating characteristic curve analyses revealed that combining the visfatin and SREBP-1c expression data increased the sensitivity (95.92%) and specificity (93.2%) for PCOS diagnoses. Conclusion: Upregulation of visfatin and SREBP-1c was observed among PCOS patients. These genes may play a role in the pathogenesis of PCOS independent of obesity. Combined visfatin and SREBP-1c analyses could be used as a noninvasive biomarker for PCOS.

Role of Multidetector Computed Tomography (CT) Virtual Hysteroscopy in the Evaluation of Abnormal Uterine Bleeding in Reproductive Age.

BACKGROUND: Abnormal uterine bleeding (AUB) may be acute or chronic and is defined as bleeding from the uterine corpus that is abnormal in regularity, volume, frequency, or duration and occurs in the absence of pregnancy. It is a widespread complaint in the primary care units. The prevalence of abnormal bleeding is up to 30% among women of reproductive age. OBJECTIVE: To assess the role of CT virtual hysteroscopy in the evaluation of the uterine cavity in cases with abnormal uterine bleeding in reproductive age. METHODS: Cross sectional study was performed at Obstetrics and Gynecology Department and Radiology Department, Zagazig University hospitals, Egypt, on 124 women with abnormal uterine bleeding in reproductive age, and their uterine cavity was evaluated by both row multidetector computed tomography (MDCT) scanner and Office hysteroscopy. RESULTS: Mean age of studied group was 28.54 ± 5.99 years, and virtual hysteroscopy showed sensitivity 91.1% and specificity 85.3% in detection of abnormalities within uterine cavity. It showed sensitivity 91.1% and specificity 85.3% in cases of endometrial polyps. It yielded 88.5 % sensitivity and 100 % specificity in cases with submucous fibroids, while it yielded only 57.9 % sensitivity and 82.9% specificity in cases of thick endometrium. CONCLUSION: Virtual CT hysteroscopy is a good negative test in cases of abnormal uterine bleeding but has some limitations that decrease its sensitivity.

Does Uterine Fibroid Adversely Affect Obstetric Outcome of Pregnancy?

BACKGROUND: Fibroid is the most common benign tumor of the uterus and if associated with pregnancy may adversely affect the outcome of pregnancy. Objective of the present study was to assess the obstetric outcome (maternal and fetal) in pregnancy with fibroid. METHODS: A prospective observational study was performed over a period from May 2015 to August 2017 at Obstetrics and Gynecology Department in Zagazig University Hospitals, Egypt. 64 pregnant patients with >2 cm fibroid were taken in the study. Routine fundamental investigations were done for all. They were followed during antenatal period clinically and scanned by ultrasonogram which was done at booking visit and during subsequent visits to assess the change in the size of the fibroid and other obstetric complications. Maternal age, parity, size of fibroid, complications during pregnancy, and mode of delivery were noted. RESULTS: 64 pregnant patients with uterine fibroids were recruited; 47 of them completed the study to the end. The average age was 31.80 ± 3.27 years, body mass index (BMI) [calculated as weight in kilograms divided by the square of height in meters] was 24.67 ± 2.46, primigravida was 23.4%, multigravida was 76.6%, duration of menstrual cycle/day was 29.68 ± 3.10, and duration of menstrual period/day was 6.46 ± 1.12. The percentage of spontaneous conception was 59.57% and 40.43% for using assisted reproductive technology. The results of obstetric outcome were spontaneous abortion in 2%, premature delivery in 27.7%, and delivery at 37-41 weeks of pregnancy in 70.2%. The mode of delivery was vaginal delivery in 15% and cesarean sections in 85%. Also, 34% had threatened miscarriage, 21% had preterm labor, 2% had antepartum bleeding in the form of placenta previa, 4% had abdominal pain needing admission, one of them underwent laparotomy and was diagnosed as red degeneration, 2 (4%) had postpartum hemorrhage, and only one needed blood transfusion. Cesarean sections were done in 85%. Neonatal outcome was acceptable with no perinatal mortality. There were no significant differences between patients with single or multiple fibroids as regards the obstetric outcome or type of fibroid either intramural or subserosal. The obstetric outcomes were not significantly affected by the number, size, or type of fibroids. CONCLUSIONS: Even most of fibroids in pregnancy are asymptomatic but may be associated with some complications affecting the course of pregnancy and labor. So, pregnancy has to be cautiously screened in the antenatal period, through regular follow-up, to detect any adverse obstetric complications and so improve the outcome.

Could Metformin Manage Gestational Diabetes Mellitus instead of Insulin?

Gestational diabetes mellitus (GDM) complicates a significant number of pregnancies. Blood glucose control improves perinatal outcomes. Medical nutrition therapy is the foundation in management. Aim of This Study. To evaluate efficacy of metformin in comparison to insulin for managing GDM. Methods. In prospective randomized comparative study, 150 antenatal women whose pregnancies had been complicated by GDM and did not respond to diet alone were recruited from antenatal clinics at Obstetrics Department in Zagazig University Hospitals from November 2012 to December 2014. They were divided randomly into two groups, 75 patients in each, and were subjected to either insulin or metformin medication. Outcomes were comparing the effects of both medications on maternal glycemic control, antenatal complications, and neonatal outcome. Results. No significant difference in controlling high blood sugar in GDM with the use of metformin or insulin (P = 0.95, 0.15). Maternal complications in both groups had no significant difference and fetal outcomes were as well similar except the fact that the hypoglycemia occurred more in insulin group with P value 0.01. Conclusion. Glycaemic control in GDM can be achieved by using metformin orally without increasing risk of maternal hypoglycemia with satisfying neonatal outcome.

Levonorgestrel-releasing intrauterine device versus dydrogesterone for management of endometrial hyperplasia without atypia.

OBJECTIVE: To compare the efficacy and safety of the levonorgestrel-releasing intrauterine device (LNG-IUD) with dydrogesterone applied for the same duration in patients having endometrial hyperplasia (EH) without atypia. MATERIALS AND METHODS: One hundred thirty eight women aged between 30 and 50 years with abnormal uterine bleeding and diagnosed as EH by transvaginal ultrasound were randomized to receive either LNG-IUD or dydrogesterone for 6 months. Primary outcome measures were regression of hyperplasia after 6 months of therapy. Secondary outcome measures were occurrence of side effects during treatment or recurrence of hyperplasia during follow-up period. RESULTS: After 6 months of treatment, regression of EH occurs in 96% of women in the levonorgestrel-releasing intrauterine system (LNG-IUS) group versus 80% of women in the oral group (P < .001). Adverse effects were relatively common with minimal differences between the 2 groups. Intermenstrual vaginal spotting and amenorrhea were more common in the LNG-IUD group (P value .01 and .0001). Patient satisfaction was significantly higher in the LNG-IUS group (P value .0001). Hysterectomy rates were lower in the LNG-IUS group than in the oral group (P = .001). Recurrence rate was 0% in the LNG-IUD group compared to 12.5% in the oral group. CONCLUSION: In management of EH without atypia, LNG-IUS achieves a higher regression and a lower hysterectomy rate than oral progesterone and could be used as a first-line therapy.

Clinicopathological correlation of endocan expression and survival in epithelial ovarian cancer.

INTRODUCTION: Endothelial-cell-specific molecule-1 or endocan is a proteoglycan with tumorigenic activity through both its glycan and protein cores. Endocan mRNA is identified as one of the most significant molecular signatures defining a poor prognosis in lung, breast, kidney, and hepatocellular cancer. OBJECTIVE: To assess the clinical value of endocan expression in ovarian cancer tissues in association with other prognostic factors and its impact on overall survival. SETTING: Oncology unit of Zagazig University Hospitals, Egypt. STUDY DESIGN: Prospective observational cohort. PATIENTS AND METHODS: One hundred primary ovarian cancer patients were recruited as study group, another 100 patients undergoing hysterectomy and oophorectomy due to uterine fibroid were the control group. Angiogenesis was determined by immunohistochemical staining, using anti-endocan, and anti vascular endothelial growth factor (VEGF) monoclonal antibodies. RESULTS: Endocan was expressed in endothelium of ovarian cancer tissue specimens in all patients with no expression in endothelium of normal ovarian tissue in the control group. VEGF was also expressed in endothelium of all specimens of ovarian cancer tissue, compared with 70% expression in normal ovarian tissue specimens in the control group. A significant association was found between endocan-microvessel density (MVD) and tumor histology, tumor size, staging, and grading. No significant association was found between VEGF expression and any of the clinicopathological variables. Overall survival of patients was inversely associated with endocan-MVD (P < 0.01). Multivariate analysis showed that endocan-MVD was an independent prognostic marker for overall survival of epithelial ovarian cancer (P < 0.01). CONCLUSION: Endocan could be a reliable marker to predict the survival in epithelial ovarian cancer patients.
