RESUMO

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.

RESUMO

Atypical squamous cells 'cannot exclude high-grade squamous epithelial lesion' (ASC-H) cytology represents clear risk and has been a controversial issue in clinical practice. The objective of this study is to investigate the diagnostic performance of p16(INK4A) immunohistochemistry (IHC) among ASC-H Pap smears in predicting high-grade cervical intraepithelial lesions. Decolourisation and staining process with p16(INK4A) is applied to 27 ASC-H diagnosed conventional Pap smears, which were all managed with colposcopy-directed cervical biopsy priorly. Staining characteristics of ASC-H Pap smears were compared with histopathological data and sensitivity-specificity values of p16 triage to detect CIN2 + histopathology were determined. The sensitivity and specificity of positive p16(INK4A) immune staining to detect CIN2 + histopathology were as 87.5% and 68%, respectively. The positive predictive value of p16 triage is found as 53.8% and negative predictive value was as 92.8%. p16(INK4A) IHC seems applicable for conventional Pap smears and may provide an alternative triage option in ASC-H category.

RESUMO

We performed a prospective study to assess the effects of a starting dose of 50 units of recombinant follicle stimulating hormone (Puregon) during gonadotrophin-releasing hormone agonist therapy (Suprecur) on follicular development in patients with clomiphene citrate-resistant polycystic ovary syndrome (PCOS). In a prospective clinical trial, 25 women with clomiphene citrate-resistant PCOS who wanted to become pregnant were treated by a low-dose step-up protocol of SC recombinant follicle stimulating hormone administration during gonadotrophin-releasing hormone agonist therapy, monitored by transvaginal ultrasonography and retrospectively by serum endocrine assays taken at each monitoring visit. Cancellation of cycles, ovulation, rate and size of follicles growth, serum E2 concentration and pregnancy were recorded. All patients exhibited a response: 22 patients ovulated, of whom 10 conceived. Using the low-dose protocol during gonadotrophin-releasing hormone agonist therapy permitted induction of ovulation safely and successfully in patients with clomiphene citrate-resistant PCOS who were patients previously difficult to treat with the conventional ovulation induction protocol.

RESUMO

We carried out this clinical study to evaluate the benefits the risks of transvaginal ultrasound-guided aspiration in a group of patients. The study group consisted of 22 premenapausal women who were detected as having benign adnexal cysts, based on ultrasound appearances. Before the procedure, all patients were evaluated thoroughly by pelvic examination, transvaginal ultrasound and serum measurements of CA-125. Oestradiol CA-125, follicle stimulating hormone, luteinising hormone and progesterone were analysed in aspirated cystic fluids as well as cytological evaluation. It was concluded that measurements of follicle stimulating hormone, luteinising hormone, oestradiol and progesterone concentrations in cystic fluid had no prognostic significance. But CA-125 levels over 55 iu/ml were likely to predict the recurrence of the cysts. Cytological examination of the aspirated cystic fluids revealed that 21 cysts were benign functional cysts, but one was serous cystadenoma. We observed recurrence following aspiration in five patients (22.7%) who were followed for 6 months. Patients with simple ovarian cysts will benefit from transvaginal ultrasound-guided aspiration by being saved from surgery and its related complications. However, its use should be limited to those masses that appear to be completely cystic with well-defined borders, because of the risk of the intra-abdominal spillage of the contents of complicated cysts.
