Expression of interleukin-8 and monocyte chemotactic protein 1 in women with endometriosis

OBJECTIVE To investigate the expression and localization of interleukin-8 (IL-8) and monocyte chemotactic protein 1 (MCP-1) in women with and without endometriosis. DESIGN Comparative immunohistochemical study. SETTING Academic medical center. PATIENT(S) Ectopic (n = 24) and homologous eutopic endometrium (n = 24) from women with endometriosis and endometrium from women without endometriosis (n = 27) were used for immunohistochemical analysis of IL-8 and MCP-1. INTERVENTION(S) Tissue sections were immunostained with antihuman IL-8 and MCP-1 antibodies. MAIN OUTCOME MEASURE(S) Microscopic evaluation to assess the presence and localization of IL-8 and MCP-1 throughout the menstrual cycle in both eutopic endometrial and endometriotic tissues of women with endometriosis and comparison with normal endometrium. RESULT(S) In normal endometrium, secretory phase samples expressed higher levels of epithelial IL-8 than in proliferative phase samples. Epithelial MCP-1 expression was similar in both proliferative and secretory phases. Proliferative phase samples showed higher epithelial IL-8 and MCP-1 expressions in eutopic endometrium of women with endometriosis compared with that of normal women. Immunoreactivities of both chemokines were significantly increased in the epithelial cells of ectopic endometrial tissues compared with those of normal endometrium. CONCLUSION(S) These findings suggest that IL-8 and MCP-1 may be involved in the pathogenesis of endometriosis.

Cytogenetic abnormalities in 179 cases with male infertility in Western Region of Turkey: Report and review

PurposeIn this study we aimed to evaluate the postnatally screened karyotype results in couples who were referred because of primary infertility between 2000 and 2006 in Izmir.MethodsThe records of a total of 179 cases were evaluated retrospectively.ResultsA total of 21 cases (11.74%) showed chromosomal alteration. Thirteen (7.26%) were 47,XXY; three (1.68%) were pericentric inversion of chromosome 9; one (0.56%) 46,XY/45,XO; one (0.56%) 46,XY/47,XXY/48,XXXY; one (0.56%) 46,XY,t(X;1); one (0.56%) 46,XY/46,XY,del(Y)(q11.2) and one (0.56%) 46,XX.ConclusionsThe rate of gonosomal chromosomal abnormalities was nearly three times higher in our region than the rate in the literature. Chromosomal analysis is strongly suggested particularly in those who suffer fertility problems.

Comparison of the ICSI outcome of ejaculated sperm with normal, abnormal parameters and testicular sperm.

OBJECTIVE(S) To compare fertilization rates, quality of embryos, pregnancy rates (PRs) and outcome of pregnancies in intracytoplasmic sperm injection (ICSI) using sperm from ejaculates of normal and abnormal semen and testicular sperm of non-obstructive azoospermia. STUDY DESIGN Four hundred fifty-four patients who underwent 454 ICSI cycles were evaluated retrospectively. Patients were divided into three groups according to the quality and source of sperm. Patients in group 1 underwent 133 cycles of ICSI using ejaculated normal semen, group 2 underwent 235 cycles using ejaculated abnormal semen, and group 3 underwent 86 cycles using testicular sperm. RESULTS The parameters were compared among the groups with respect to cycles induced by long (n = 160) and short (n = 294) protocol. In group 3, the fertilization and PRs were significantly lower than in all other groups (51.3 and 10.6% in the long protocol cycles, 53.3 and 5.1% in the short protocol cycles, respectively). There was no significant difference in the outcome of pregnancies in respect to abortion rates between different groups. CONCLUSION(S) The fertilizing ability of sperm in ICSI is highest with ejaculated sperm and lowest with sperm extracted by testicular biopsy. Also, the clinical PRs are significantly lower in ICSI with sperm from testicular biopsy. However, the outcomes of pregnancies are not affected by using surgically retrieved sperm from ejaculated semen.

Gluteal artery pseudoaneurysm, a rare cause of sciatic pain: case report and literature review.

This article describes a very unusual case of sciatic pain and motor dysfunction resulting from gluteal artery pseudoaneurysm. A 36-year-old woman with primary infertility sustained an iatrogenic injury to her left gluteal artery during transvaginal ultrasound-guided follicle aspiration. Twenty-five days after the procedure she developed severe left sciatic pain and motor dysfunction. Pelvic computed tomography and magnetic resonance imaging revealed a huge pelvic hematoma. Angiography demonstrated a gluteal artery pseudoaneurysm. Because endovascular occlusion of the aneurysm did not relieve the pain, the patient underwent surgery for evacuation of the hematoma and release of the lumbosacral plexus. This eliminated all her sciatic pain and restored her motor dysfunction completely. The English literature details only five other cases of sciatic pain resulting from gluteal artery aneurysm, and these reports are also discussed.

Bilateral Jugular Venous Thromboembolism and Pulmonary Emboli in a Patient with Severe Ovarian Hyperstimulation Syndrome

We report here a case of severe ovarian hyperstimulation syndrome with massive ascites in a 25‐year‐old woman with a history of primary infertility after an IVF‐ET cycle. At the 9th gestational week she presented with neck pain and dyspnea and duplex Doppler sonographic examination of the neck veins revealed bilateral jugular venous thrombosis. Despite prompt administration of low‐molecular weight heparin, pulmonary emboli developed a few days later.

Long-term use of gonadotropin-releasing hormone analogues before IVF in women with endometriosis.

Purpose of review To discuss the relationship between endometriosis and infertility, the impact of endometriosis on assisted reproductive techniques and also the benefits of prolonged use of gonadotropin-releasing hormone analogue before IVF in women with endometriosis. Recent findings The available evidence suggests that endometriosis is strongly associated with infertility. Many studies indicate lower pregnancy and implantation rates even in assisted reproductive cycles in women with endometriosis. It is well known that medical suppression of endometriosis does not appear to be warranted for endometriosis-associated infertility. Prolonged pretreatment with gonadotropin-releasing hormone analogue before IVF has been reported to improve clinical pregnancy rates in infertile women with endometriosis. Summary Based on the recently published data, infertile women with endometriosis may benefit from long-term pretreatment of gonadotropin-releasing hormone analogue prior to IVF.

Relationship of follicle number, serum estradiol level, and other factors to clinical pregnancy rate in gonadotropin-induced intrauterine insemination cycles

Abstract  Objective:To determine the characteristics associated with clinical pregnancy rate after gonadotropin-induced intrauterine insemination cycles in patients without male or tubal factor infertility. Materials and methods:One hundred and eighty patients undergoing controlled ovarian hyperstimulation followed by intrauterine insemination were included in the study retrospectively. The patients’ files were retrospectively evaluated with respect to age, number of follicles, endometrial thickness and serum hormone levels at baseline and at the day of human chorionic gonadotropin (hCG) administration. The patients with male or unilateral tubal factor infertility were excluded from the study. Results:The serum estradiol level at the day of hCG administration was not correlated with the clinical pregnancy rate (r=–0.05, p=0.481). The number of follicles was not correlated with the clinical pregnancy rate (r=–0.09, p=0.209). There was no significant difference between the clinically pregnants (n=32) and not pregnants (n=148) regarding the mean age, baseline serum levels of luteinizing hormone (LH) and estradiol, serum estradiol and LH levels at the day of hCG administration and endometrial thickness (p>0.05). Although not statistically significant, a pregnancy rate of 14.2% with less than 3 follicles ≥18 mm is present compared to a pregnancy rate of 27.5% with at least 3 follicles ≥18 mm and 24% with ≥4 follicles ≥18 mm. Conclusion: The clinical pregnancy rate does not seem to be affected with the number of follicles present at the time of intrauterine insemination or the serum estradiol level at the day of hCG administration in a controlled ovarian hyperstimulation cycle in non-andrologic and non-peritubal factor infertility; however, there is a clear trend towards higher pregnancy rates with higher number of follicles.

Comparison of short and long ovulation induction protocols used in ART applications according to the ovarian response and outcome of pregnancy.

Abstract This retrospective study was designed to determine whether there is any difference between short and long protocol ovulation induction with Gonadotropin Releasing Hormone agonist (GnRHa) and gonadotropins used in Assisted Reproductive Technology (ART) applications according to the number of retrieved oocytes, oocyte maturity, fertilization rates, embryo quality and the outcome of pregnancies. 240 cycles consisting of in vitro fertilization (IVF) cycles without andrologic factor and intracytoplasmic sperm injection (ICSI) cycles were evaluated. 112 cycles which were induced by short protocol GnRHa and Follicle Stimulating Hormone (FSH) + Human Menopausal Gonadotropin (HMG) combinations and 128 cycles which were induced by long protocol GnRHa and FSH + HMG combinations were compared according to the number of retrieved oocytes, cancellation rate of cycles, oocyte maturity, fertilization rates, embryo quality and pregnancy rates. The cancellation rate for short protocol cycles were found to be significantly higher than those with long protocol. The number of retrieved oocytes, mature oocytes and fertilized oocytes were also found significantly lower. The quality of embryos did not show any significant difference between these groups. The clinical pregnancy rates were evidently found to be high in the long protocol cycles. As a conclusion we have found that while the number of retrieved oocytes, mature oocytes, fertilized oocytes and clinical pregnancy rates were increasing, the cancellation rate of cycles were decreasing significantly in ART cycles induced by long protocol.

Unilateral Ectopic Twin Pregnancy Following an IVF Cycle

We report here a 37‐year‐old woman who underwent ovulation induction and in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatment because of infertility who developed vaginal bleeding at the 6th week of gestation. Abdominal ultrasonography was insufficient to distinguish the intrauterine gestational sac. Subsequently, vaginal doppler ultrasonography detected two separate unilateral twin ectopic pregnancies with cardiac activity in both fetuses, which were operated on pelviscopically.
