RESUMO

Kisspeptin (KP) is a group of hypothalamic neuropeptides encoded by KISS-1 gene. KP-54, a 54-amino-acid peptide, helps regulate the hypothalamic-pituitary-ovarian axis and plays a potential role in implantation. C57BL/6 J female mice were superovulated via intraperitoneal injection of 5 International Units (IU) pregnant mare serum gonadotrophin (day 1). Forty-eight hours later, mice (5/group) were injected with phosphate-buffered saline (PBS) (group A), 5 IU human chorionic gonadotrophin (hCG) (group B), or 3 nmol KP-54 (group C). On day 7, mice were euthanized and uteri excised to create paraformaldehyde-fixed paraffin-embedded sections that were immunostained for the implantation markers: leukemia inhibitory factor (LIF) and integrin αVß3 (ITG αVß3). Slides were scored for intensity of staining in endometrial glandular epithelium (GE) and stromal cells (SCs) via histoscore (H-score). Data were analyzed using the Kruskal-Wallis test followed by the Mann-Whitney U test for pairwise comparisons. LIF expression was significantly higher in GE and SCs of mice triggered with KP-54 compared to placebo (P = .009 for both), but only higher than hCG trigger group in SCs (P = .009). Meanwhile, ITG αVß3 expression was significantly higher in SCs of mice triggered with KP-54 compared to placebo (P = .028). In conclusion, using KP-54 as an ovulation trigger resulted in higher expression of the implantation markers LIF and ITG αVß3 in mice endometrium compared to hCG or placebo. This suggests a potential role for KP-54 trigger in improving embryo implantation in clinical IVF. However, further studies are needed to correlate these results with clinical implantation rates and pregnancy outcomes.

RESUMO

Endometriosis is characterized by the presence of ectopic endometrial tissues. Mechanisms of tissue dissemination in endometriosis may be similar to those involved in tumor metastasis. We hypothesize that dysregulation of kisspeptin (KISS1), a metastasis suppressor in endometrial carcinoma, may contribute to the pathogenesis of endometriosis. In this study, we characterized the immunoreactivity of kisspeptin and its receptor, KISS1R, in eutopic and ectopic endometrial tissue of women with and without endometriosis, in proliferative and secretory menstrual cycle phases. Immunohistochemistry was performed using KISS1 and KISS1R antibodies on samples from women with (n = 35) and without (n = 14) endometriosis. Samples from women with endometriosis included eutopic endometrium (n = 20) samples, superficial endometriotic implants (SUP, n = 10) deep infiltrating endometriotic implants (DIE, n = 15), and ovarian endometriomas (OMA, n = 15). Immunoreactivity was quantified using histoscores. KISS1 and KISS1R immunoreactivity was significantly lower in eutopic endometrial stroma of women with versus without endometriosis, regardless of the menstrual cycle phase (P = 0.001 and P = 0.015 respectively). In endometriotic implants, KISS1 levels were significantly lower in both glandular and stromal components of DIE (P < 0.01) and OMA (P < 0.01) compared to SUP. KISS1R immunoreactivity was lower in the glandular component of OMA (P = 0.035) compared to SUP. KISS1 and KISS1R levels are lower in eutopic endometrial stroma from women with versus without endometriosis, consistent with a role for decreased KISS1 expression in the pathogenesis of endometriosis. As deeply invasive lesions showed lower KISS1 levels than superficial lesions, downregulation of KISS1 levels may contribute to implant invasiveness.

RESUMO

OBJECTIVE: To evaluate the effects of cytokine enrichment of culture medium on embryological and clinical outcomes after intracytoplasmic sperm injection (ICSI). DESIGN: A randomized clinical trial. SETTING: In vitro fertilization centers. PATIENT(S): This trial included 443 ICSI cycles randomized into two groups. INTERVENTION(S): This study evaluated the influence of integration of granulocyte-macrophage colony-stimulating factor, heparin-binding epidermal growth factor-like growth factor, and leukemia inhibitory factor into culture media on human embryo development after ICSI. MAIN OUTCOME MEASURE(S): Ongoing pregnancy rate per a randomized participant. RESULT(S): Cytokine enrichment of culture medium showed improvement in ongoing pregnancy rate compared with no cytokines (106/224 [47%] vs. 78/219 [36%]; absolute rate difference [ARD] = 12; 95% confidence interval [CI], 2.5-21). This integration of cytokines also showed better rates of live birth (101/224 [45%] vs. 71/219 [33%]; ARD = 13; 95% CI, 4-21) and cumulative live birth (132/224 [60%] vs. 97/219 [44%]; ARD = 12; 95% CI, 4-20) and lower rate of pregnancy loss (27/124 [22%] vs. 37/103 [36%]; ARD = -14; 95% CI, -26 to -2) than conventional medium. Embryos developed in the cytokine-supplemented medium showed better blastocyst formation, quality, cryopreservation, and use than control medium. CONCLUSION(S): Integration of cytokines into human embryo culture media showed improvement in embryological and clinical outcomes after ICSI. However, the long-term effect of cytokine enrichment of a medium is still unclear and warrants further studies with longitudinal follow-up. CLINICAL TRIAL REGISTRATION NUMBER: NCT02420886 at ClinicalTrials.gov.

RESUMO

OBJECTIVE: To evaluate the impact of bilateral internal iliac artery ligation (BIL), bilateral uterine artery ligation (BUAL), step-wise uterine devascularization (SWUD), and B-Lynch on infertility, ovarian reserve, and pregnancy outcome. METHODS: The study included 168 infertile or pregnant patients-recruited at outpatient clinics in Egypt-who had previously undergone uterine-sparing surgery (BIL [group I], n=59; SWUD [group II], n=65); BUAL [group III], n=2; and B-Lynch [group IV], n=42). One-way analysis of variance was used to compare the prevalence of infertility, the status of ovarian reserve, and the prevalence and type of relevant maternal and/or fetal obstetric complications between the groups. RESULTS: Groups II and IV had the highest prevalences of infertility. The ovarian reserve was significantly lower in group II. Unexplained infertility was the predominant cause of infertility in group I, anovulation and premature ovarian failure in group II, and endometriosis and intrauterine adhesions in group IV. The frequency of obstetric complications, particularly placenta previa and preterm labor, was high in group IV. CONCLUSION: Of the 4 procedures, BIL had the least deleterious effect on reproductive performance; SWUD increased the risk of premature ovarian failure, and B-Lynch increased the risks of endometriosis, intrauterine adhesions, placenta previa, and preterm labor.

RESUMO

OBJECTIVE: To evaluate maternal, fetal, and neonatal outcomes and their associated risk factors among pregnant women with liver cirrhosis (LC). METHODS: A prospective cohort study was conducted at Sohag University Hospital, Egypt, between May 1, 2009, and April 1, 2012. Participants included 129 pregnant women with LC (study group), 647 pregnant women without LC (control group 1), and 853 non-pregnant women with LC (control group 2). Univariate and multivariate analyses were performed. RESULTS: Maternal, fetal, and neonatal complication rates were significantly higher in the study group than in control group 1 (P=0.001 for all complications). The rate of hepatic decompensation (HD) was higher in the study group than in control group 2 (63.6% vs 13.6%; P=0.001). Maternal mortality was higher in the study group (7.8%) than in either control group 1 (0.2%) or control group 2 (2.5%; P=0.001). Variceal bleeding during vaginal delivery was the most frequent cause of maternal mortality. Vaginal delivery and increasing gestational age were the key variables affecting the rate of HD (P=0.001 for both). CONCLUSION: The presence of LC during pregnancy was associated with high rates of maternal and neonatal complications. Increasing gestational age and vaginal delivery were the most important risk factors for HD.

RESUMO

OBJECTIVE: To evaluate the clinical and mycological cure rates of a novel mixture consisting of Bee-honey and yogurt compared to local antifungal agents for treating patients with vulvo-vaginal candidiasis (VVC) during pregnancy. MATERIALS AND METHODS: This is a prospective comparative study which included 129 patients with VVC during pregnancy. The participants were allocated into study group (n = 82) who received a mixture of Bee-honey and yogurt vaginally and control group (n = 47) who received local anti-fungal agents. The Chi-square test was used to evaluate the clinical and mycological cure rates and the side-effects of both modes of therapy. RESULTS: The clinical cure rate was significantly higher in the study than the control group (87.8 vs. 72.3%, respectively) while the mycological cure rate was higher in the control than the study group (91.5 vs. 76.9%, respectively). Both types of therapy were favorably tolerated by most of the patients. Side effects were reported only in 24.3 and 29.7% of patients in group I and II, respectively (p < 0.05). CONCLUSIONS: The mixture of Bee-honey and yogurt produced a high clinical cure rate and a reasonable mycological cure rate. It can be used as a complementary or an alternative to antifungal agents especially in patients with VVC during pregnancy.

RESUMO

OBJECTIVE: To evaluate the rate and pattern of complications associated with use of the Copper T 380A intrauterine device (IUD) among adolescents. METHODS: A prospective comparative study of women eligible for IUD insertion who attended the family planning clinic of Sohag University Hospital, Egypt, between July 1, 2008 and December 31, 2010. The participants were categorized as adolescents or adults. The Copper T 380A IUD was inserted in all participants and follow-up visits were scheduled at 1, 3, and 6 months. Odds ratio and χ(2) square tests were used to compare the rates of complications at each visit. RESULTS: Of 1512 patients eligible for IUD insertion, 852 met the inclusion criteria: 281 adolescents and 571 adults. The rates of pain, bleeding, displacement, expulsion, and removal of IUDs were significantly higher in adolescents (P<0.05). The rates of these complications were high in adolescents younger than 16 years; the rates then decreased with age and became comparable with the adult rates at 18 years of age. CONCLUSIONS: IUD-associated complications were high in adolescents up to the age of 17 years. Our data suggest that adolescents younger than 18 years of age should be counseled carefully before IUD insertion, and examined more frequently to detect displacement or expulsion of the device.

RESUMO

OBJECTIVE: To evaluate the possible role of hydatid of Morgagni in patients with unexplained infertility. STUDY DESIGN: This was a non-randomized controlled trial conducted at the Department of Obstetrics and Gynecology of Sohag University, Egypt. Two hundred and thirteen patients with unexplained infertility and hydatid of Morgagni diagnosed at laparoscopy were included. The laterality (bilateral vs unilateral), location (fimbrial vs juxta-fimbrial), number (single vs multiple) and diameter of the hydatids of Morgagni were recorded. Patients were allocated to a study group (n=127) who underwent laparoscopic excision of hydatid of Morgagni and a control group (n=86) who underwent no intervention. Patients were followed for six months without any infertility or hormonal treatment to detect spontaneous pregnancy. Patients missed during the follow-up or who received infertility treatment were excluded. Statistical analysis was done using Chi-square test and Student's t-test. To find the most important character of hydatid of Morgagni which impedes pregnancy, logistic regression analysis of the dependent variable (no pregnancy) and independent variables (different characters of hydatid of Morgagni) was carried out in the control group. RESULTS: Hydatid of Morgagni was detected in 52.1% of patients with unexplained infertility compared to 25.6% of those with explained infertility (p<0.001). The pregnancy rate was higher in the study group than the control group (58.7% vs 20.6%, p<0.001). The pregnancy rate was significantly higher in the study group than the control group if the hydatid cyst was bilateral (85.7% vs 5.3%, p<0.001), fimbrial (85.6% and 9.1%, p<0.001), single (57.6% and 30.3%, p<0.001) or 1-2 cm in diameter (58.1% and 25.5%, p<0.001). Logistic analysis showed that the bilaterality and fimbrial location of the hydatid of Morgagni were the most significant characteristics impeding pregnancy (odds ratio=7.27 and 3.67 respectively). CONCLUSIONS: Hydatid of Morgagni is a possible underestimated cause of unexplained infertility. Laparoscopic removal of hydatid of Morgagni in patients with unexplained infertility was followed with a high spontaneous pregnancy rate. This is particularly obvious with bilateral and fimbrial hydatid of Morgagni.

RESUMO

OBJECTIVE: To estimate the influence of the 2007 criminalization law on the prevalence and yearly incidence of female genital mutilation (FGM) in Upper Egypt and assess the attitudes of both the population and their health providers toward FGM. METHODS: Between September 15, 2008, and September 15, 2010, all girls and young women presenting at the Departments of Gynecology and Obstetrics or Pediatrics of Sohag and Qena University Hospitals were invited to answer a questionnaire, which was also presented to their parents. Another questionnaire was presented to all nurses, young physicians, and senior physicians working at either hospital. RESULTS: The prevalence of FGM was 89.2%. The incidence was 9.6% in 2000, began to decrease in 2006, and had reached 7.7% at the end of the study period in 2009 (P=0.05). In their vast majority, the procedures were performed by general practitioners. In total, 88.2%, 34.3% and 14.9% of nurses, young physicians, and senior physicians, respectively, approved the practice. CONCLUSION: The incidence of FGM is still very high in Upper Egypt in spite of the criminalization law. While general practitioners perform most procedures, most nurses are in favor of preserving the practice.
