Age and dual trigger were found to be significant predictors of live birth in POSEIDON group 3 and 4 women treated with the GnRH antagonist protocol: a retrospective cohort study.

OBJECTIVE: Despite recent advancements in assisted reproductive technology (ART), the effective management of patients with poor ovarian response (POR) remains a formidable challenge. While various treatment strategies and predictors of live births have been documented to provide guidance to fertility specialists in managing poor responders, research efforts have predominantly encompassed all POSEIDON groups. In this study, our objective was to analyze the factors correlated with live births (LB) within a subset of the POSEIDON groups, with a particular focus on POSEIDON groups 3 and 4. PATIENTS AND METHODS: Charts of 406 patients belonging to POSEIDON groups 3 and 4 who underwent ART treatment at a university-affiliated infertility clinic following a gonadotropin-releasing hormone (GnRH) antagonist cycle between January 2016 and December 2021 were analyzed. Clinically significant factors associated with live births were incorporated into a logistic regression model for multivariate analysis to ascertain independent predictors of LB. Additionally, a receiver operating characteristic (ROC) curve analysis was conducted to establish the optimal cut-off values. RESULTS: Live births were achieved in 48 cycles (8.7%). Female age (OR, 0.930; 95% CI: 0.874-0.991; p < 0.024), baseline serum luteinizing hormone (LH) levels (OR, 0.854; 95% CI: 0.741-0.984; p < 0.029), and dual triggers (OR, 4.004; 95% CI: 1.290-12.426; p < 0.016) were identified as independent factors associated with LB following multivariate logistic regression analysis. The optimal age cut-off was determined to be 33 years, with a sensitivity of 70.8% and specificity of 75%. CONCLUSIONS: Younger age, lower baseline serum LH levels, and dual-trigger administration appear to enhance the likelihood of live birth in POSEIDON groups 3 and 4 following treatments with the GnRH antagonist protocol.

Dual suppression with oral contraceptive pills in GnRH antagonist cycles for patients with polycystic ovary syndrome undergoing intracytoplasmic sperm injection.

OBJECTIVE: To evaluate the effects of a gonadotropin-releasing hormone (GnRH) antagonist protocol, with or without oral contraceptive pill (OCP) pretreatment, in patients with polycystic ovary syndrome (PCOS) undergoing intracytoplasmic sperm injection (ICSI). STUDY DESIGN: In this retrospective cohort study, 410 infertile patients with PCOS were assessed in their first ICSI cycles between January 2006 and June 2013. In Group A (n=208), patients underwent a long luteal GnRH agonist protocol, and in Groups B (n=143) and C (n=59), patients underwent a GnRH antagonist protocol. The patients in Group C also received OCPs containing 30mg of ethinyl oestradiol and 3mg of drospirenone prior to treatment. The main outcome measures were pregnancy and ovarian hyperstimulation syndrome (OHSS) rates. RESULTS: Demographic features, body mass index, duration of infertility, serum baseline hormone levels, cycle outcomes, multiple pregnancy rates, miscarriage rates, OHSS rates, total number of Grade A embryos and total number of transferred embryos were comparable between the groups. Clinical pregnancy rates were 27.4%, 26.6% and 23.7% in Groups A, B and C, respectively (p=0.853). CONCLUSIONS: OCP pretreatment was found to have no beneficial or adverse effects in patients with PCOS undergoing a GnRH antagonist protocol for ICSI, but can be used for cycle scheduling.

The effect of total abdominal hysterectomy on serum anti-Müllerian hormone levels: a pilot study.

OBJECTIVE: To evaluate the effect of hysterectomy on levels of serum anti-Müllerian hormone (AMH), an indicator of ovarian reserve. METHOD: Twenty-two premenopausal women between 40 and 50 years of age who underwent total abdominal hysterectomy for uterine leiomyoma were enrolled to the patient group and unaffected women in a similar age range constituted the control group. Samples were collected preoperatively and at the 4th month postoperatively from the patients and two times at 4 months apart from the controls. Serum AMH levels were detected with enzyme-linked immunosorbent assay and compared within each group and between groups. RESULTS: Baseline serum AMH values were similar (1.46 ± 2.02 ng/ml for the hysterectomy group and 1.53 ± 1.82 ng/ml for the control group, p = 0.73). Serum AMH levels at month 4 decreased to 0.62 ± 0.9 ng/ml and 1.26 ± 1.78 ng/ml for hysterectomy patients and controls, respectively (p = 0.001 and < 0.001, respectively). Although the percentage median decrease was higher in hysterectomized women (58.9% vs. 28.5%), this was statistically insignificant (p = 0.26). CONCLUSION: Although not statistically significant, our study demonstrated that total abdominal hysterectomy causes 30% more loss of ovarian reserve in addition to the effects of aging. Further research on larger populations is needed to confirm our results and to apply them in clinical practice.

Preliminary experience with salvage weekly paclitaxel in women with advanced recurrent ovarian carcinoma.

PURPOSE OF INVESTIGATION: To assess the role of palliative chemotherapy with weekly paclitaxel in patients with recurrent ovarian cancer. METHODS: Thirty-two patients with paclitaxel- and platinum-resistant ovarian cancer were treated with weekly paclitaxel at 80 mg/m2 as a 1-hour intravenous infusion weekly for six weeks every eight weeks (1 cycle). This schedule was considered to be given for three cycles. Evaluation of radiographically measurable disease was used in the assessment of response. CA-125 was used to classify responses only in the absence of a measurable lesion. RESULTS: Thirty-two patients were all assessable for response. Of these, nine patients (28.1%) achieved a partial response and one patient achieved a complete response, leading to an overall response rate of 31.2%. Stable disease occurred in six patients (18.8%), and 16 patients (50%) had progressive disease. Nine patients died of progressive disease while on treatment. The median survival for the entire group was 10.5 months (range 2.5-22 months). Grade 3 or 4 leukopenia and neutropenia occurred in eight and six patients, respectively. Four of these patients developed febrile neutropenia without infection. Grade 1 and 2 peripheral neuropathies were observed in 50% of the patients without causing any premature drop out. Severe (grade 3 or 4) peripheral neuropathy was not observed. There were 11 patients with grade 1 or 2 myalgias. CONCLUSION: Weekly paclitaxel regimen is well tolerated with acceptable toxicity. The favorable toxicity profile and the encouraging antitumor activity observed in this study makes this regimen an option for the salvage treatment of patients with recurrent ovarian cancer.

Increased insulin-like growth factor-I levels in women with polycystic ovary syndrome, and beneficial effects of metformin therapy.

We aimed to investigate whether metformin would reverse the endocrinopathy of polycystic ovary syndrome (PCOS), allowing resumption of cyclic ovulation and regular menses, and whether metformin causes any change in the serum concentration of insulin-like growth factor-I (IGF-I) in patients with PCOS. Fifty-eight women with PCOS participated in the study and received metformin at a dose of 850 mg three times a day (total 2550 mg) for 16 weeks. Serum concentrations of luteinizing hormone, follicle stimulating hormone, estradiol, free testosterone, total testosterone, 17-hydroxyprogesterone, dehydroepiandrosterone sulfate, fasting insulin, IGF-I, sex hormone binding globulin and insulin-like growth factor binding protein-1 (IGFBP-1) were evaluated before and after metformin treatment. Patients were divided into two groups as responders and non-responders according to the achievement of regular menstrual periods. The mean IGF-I levels decreased significantly on metformin therapy. After 16 weeks of metformin treatment, 55.17% of PCOS patients achieved regular menses. Only the change in serum levels of progesterone and IGF-I on metformin were statistically significant between responders and non-responders; metformin-induced decremental change in IGF-I levels were greater in responders. In conclusion, we observed that elevated IGF-I levels may have a crucial role in many consequences of PCOS in addition to hyperinsulinemia. By decreasing insulin and IGF-I levels, metformin therapy offers additional beneficial effects in resumption of regular menses. Thus, in PCOS patients with elevated levels of IGF-I, metformin may be considered as an appropriate agent to be used for the regulation of menstrual cycles.

Prognostic value of p53 accumulation in epithelial ovarian carcinomas.

AIM: To evaluate the prognostic significance of p53 expression in epithelial ovarian carcinomas (EOC), and to look for correlations between p53 and other disease parameters. MATERIAL AND METHODS: Immunohistochemical techniques were used to evaluate p53 expression in paraffin-embedded tissue specimens of 50 EOC cases. RESULTS: p53 immunoreactivity was present in 33 of the 50 cases (66%). The expression of the p53 did not show any association with the tumor histologic type, grade or with the disease stage. However, p53 accumulation was significantly more prevalent among tumors with high mitotic index ( p<0.01). Although median survival was low in the p53 negative cases, this biologic marker did not reveal as an independent prognostic factor in Cox's regression analysis. CONCLUSION: Abnormalities of p53 expression which is an inducer of apoptosis occur commonly in EOC. Although we could not find it as an independent prognostic factor, p53 expression should be studied in larger series to reveal its accurate prognostic significance.

Tubal pregnancy after pomeroy sterilization.

Tubal sterilization is one of the options chosen by the women who have completed their fertility. Although ectopic pregnancy after tubal sterilization is rare, all women undergoing this procedure should be informed about the risk of it. An ectopic pregnancy in a 36-year-old woman who had undergone tubal sterilization is described.

Prognostic significance of apoptotic index and bcl-2 and p53 expression in epithelial ovarian carcinoma.

PURPOSE OF THE STUDY: To determine if bcl-2 and p53 expression, and apoptotic index (AI) were associated with patient outcome in epithelial carcinomas of the ovary (EOC) and therefore useful as prognostic factors to predict survival. METHODS: A total of 50 women with epithelial carcinomas of the ovary were retrospectively analyzed. The archival paraffin-embedded material of of these cases were evaluated for expression of p53 and bcl-2 by immunohistochemical techniques. Apoptotic cells were detected with an in situ hybridisation method. RESULTS: A total of 33 (66%) of 50 cases showed positive immunoreactivity for the p53 antibody. Twenty-four of the 50 cases showed positive bcl-2 protein expression. Median value for AI was found to be 2.48. No statistically significant association was found between bcl-2 and p53 expression and clinicopathologic features. Univariate survival analysis of AI failed to reveal any effect on prognosis in the study population. CONCLUSION: We found neither p53 nor bcl-2 immunoreactivity to be of prognostic significance in patients with EOC. In addition, AI was not found to be an independent prognostic factor.
