RESUMO

PURPOSE OF REVIEW: Identify the most recent and significant evidence regarding the ovulation trigger within the framework of a multicycle approach through DuoStim, providing valuable insights for improving treatment strategies in patients with a poor prognosis. RECENT FINDINGS: The trigger method plays a pivotal role in optimizing in-vitro fertilization (IVF) stimulation, influencing oocyte retrieval and maturation rates, as well as follicle recruitment in consecutive ovarian stimulations such as double stimulation. Decision-making involves multiple factors and, while guidelines exist for conventional stimulation, specific recommendations for the multicycle approach are not well established. SUMMARY: The different methods for inducing oocyte maturation underscore the need for personalization of IVF protocols. The GnRH agonist trigger induces rapid luteolysis and establishes favorable hormonal conditions that do not adversely affect the recruitment of consecutive follicular waves in the context of DuoStim. It serves as a valid alternative to hCG in freeze-all cycles. This strategy might enhance the safety and flexibility of ovarian stimulations with no impact on oocyte competence and IVF efficacy.

RESUMO

OBJECTIVES: Metastatic prostate cancer is the most common malignant cancer and the second leading cause of death due to various types of cancer among men after lung cancer. This study aimed to analyze the cost-effectiveness of triptorelin, goserelin, and leuprolide in the treatment of the patients with metastatic prostate cancer from the societal perspective in Iran in 2020. METHODS: This is a cost-effectiveness study in which a 20-year Markov transition modeling was applied. In this study, local cost and quality-of-life data of each health state were gathered from cohort of patients. The TreeAge pro 2020 and Microsoft Excel 2016 software were used to simulate cost-effectiveness of each treatment in the long term. The one-way and probabilistic sensitivity analyses were also performed to measure robustness of the model outputs. RESULTS: The findings indicated that the mean costs and utility gained over a 20-year horizon for goserelin, triptorelin, and leuprolide treatments were $ 13 539.13 and 6.365 quality-adjusted life-years (QALY), $ 18 124.75 and 6.658 QALY, and $ 26 006.92 and 6.856 QALY, respectively. Goserelin was considered as a superior treatment option, given the estimated incremental cost-effectiveness ratio. The one-way and probabilistic sensitivity analyses confirmed the robustness of the study outcomes. CONCLUSIONS: According to the results of the present study, goserelin was the most effective and cost-effective strategy versus 2 other options. It could be recommended to policy makers of the Iran healthcare system to prioritize it in clinical guidelines and reimbursement policies.

RESUMO

CONTEXT: The role of body modifications induced by gonadal suppression in transgender and gender diverse adolescents on psychological functioning has not yet been evaluated. OBJECTIVE: The main aim of the present study was to explore several hormone, physical and psychological functioning changes during gonadotropin-releasing hormone analog (GnRHa) treatment in transgender and gender diverse adolescents (TGDAs). The potential relationship between the physical and hormone effects of GnRHa and psychological well-being, along with its magnitude, was assessed for the first time. METHODS: This prospective multidisciplinary study included 36 TGDA (22 assigned female at birth, and 14 assigned male at birth) who received psychological assessment followed by triptorelin prescription after referring to the Florence Gender Clinic. This study consisted of 3 time points: first referral (T0), psychological assessment (T1); and treatment with intramuscular injections of triptorelin for 3 up to 12 months (T2). Psychometric questionnaires were administered at each time point, and clinical and biochemical evaluations were performed at T1 and T2. RESULTS: The following results were found: (1) GnRHa showed efficacy in inhibiting puberty progression in TGDAs; (2) an increase in psychopathology was observed before starting GnRHa (T1) compared with baseline levels; (3) during GnRHa treatment (T2), a significant improvement in psychological functioning, as well as decrease in suicidality, body uneasiness, depression, and anxiety levels were observed; (4) hormone and physical changes (in terms of gonadotropin and sex steroid levels, height and body mass index percentiles, waist-hip ratio, and acne severity) observed during triptorelin treatment significantly correlated with a reduction in suicidal ideation, anxiety, and body image concerns. CONCLUSION: Psychological improvement in TGDA on GnRHa seems to be related to the objective body changes induced by a GnRHa. Therefore, the rationale for treatment with a GnRHa may not only be considered an extension of the evaluation phase, but also the start of a medical (even if reversible) gender-affirming path, especially in TGDAs whose puberty has already progressed.

RESUMO

Background: Triptorelin, a long-acting gonadotropin-releasing hormone (GnRH) agonist, is available in 1-, 3-, and 6-month formulations to treat central precocious puberty (CPP). The triptorelin pamoate 22.5-mg 6-month formulation recently approved for CPP offers greater convenience to children by reducing the injection frequency. However, worldwide research on using the 6-month formulation to treat CPP is scarce. This study aimed to determine the impact of the 6-month formulation on predicted adult height (PAH), changes in gonadotropin levels, and related variables. Methods: We included 42 patients (33 girls and nine boys) with idiopathic CPP treated with a 6-month triptorelin (6-mo TP) formulation for over 12 months. Auxological parameters, including chronological age, bone age, height (cm and standard deviation score [SDS]), weight (kg and SDS), target height (TH), and Tanner stage, were evaluated at baseline, and after 6, 12, and 18 months of treatment. Hormonal parameters, including serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and estradiol for girls or testosterone for boys, were analyzed concurrently. Results: The mean age at treatment initiation was 8.6 ± 0.83 (8.3 ± 0.62 for girls, 9.6 ± 0.68 for boys). The peak LH level following intravenous GnRH stimulation at diagnosis was 15.47 ± 9.94 IU/L. No progression of the modified Tanner stage was observed during treatment. Compared to baseline, LH, FSH, estradiol, and testosterone were significantly reduced. In particular, the basal LH levels were well suppressed to less than l.0 IU/L, and the LH/FSH ratio was less than 0.66. The bone age/chronological age ratio remained stable with a decreasing trend (1.15 at the start of treatment, 1.13 at 12 months, 1.11 at 18 months). PAH SDS increased during treatment (0.77 ± 0.79 at baseline, 0.87 ± 0.84 at the start of treatment, 1.01 ± 0.93 at six months, and 0.91 ± 0.79 at 12 months). No adverse effects were observed during treatment. Conclusion: The 6-mo TP suppressed the pituitary-gonadal axis stably and improved the PAH during treatment. Considering its convenience and effectiveness, a significant shift to long-acting formulations can be expected.

RESUMO

CONTEXT: Limited data exist regarding whether the endocrine response to the gonadotropin-releasing hormone receptor agonist (GnRHa) triptorelin differs in women with polycystic ovary syndrome (PCOS) compared with healthy women or those with hypothalamic amenorrhea (HA). OBJECTIVE: We compared the gonadotropin response to triptorelin in healthy women, women with PCOS, or those with HA without ovarian stimulation, and in women with or without polycystic ovaries undergoing oocyte donation cycles after ovarian stimulation. METHODS: The change in serum gonadotropin levels was determined in (1) a prospective single-blinded placebo-controlled study to determine the endocrine profile of triptorelin (0.2 mg) or saline-placebo in healthy women, women with PCOS, and those with HA, without ovarian stimulation; and (2) a retrospective analysis from a dose-finding randomized controlled trial of triptorelin (0.2-0.4 mg) in oocyte donation cycles after ovarian stimulation. RESULTS: In Study 1, triptorelin induced an increase in serum luteinizing hormone (LH) of similar amplitude in all women (mean peak LH: healthy, 52.3; PCOS, 46.2; HA, 41.3 IU/L). The AUC of change in serum follicle-stimulating hormone (FSH) was attenuated in women with PCOS compared with healthy women and women with HA (median AUC of change in serum FSH: PCOS, 127.2; healthy, 253.8; HA, 326.7 IU.h/L; P = 0.0005). In Study 2, FSH levels 4 hours after triptorelin were reduced in women with at least one polycystic morphology ovary (n = 60) vs normal morphology ovaries (n = 91) (34.0 vs 42.3 IU/L; P = 0.0003). Serum anti-Müllerian hormone (AMH) was negatively associated with the increase in FSH after triptorelin, both with and without ovarian stimulation. CONCLUSION: FSH response to triptorelin was attenuated in women with polycystic ovaries, both with and without ovarian stimulation, and was negatively related to AMH levels.

RESUMO

Central precocious puberty (CPP) is defined as the appearance of secondary sexual signs in girls younger than eight years of age or the onset of menarche before the age of 10 years. Gonadotropin-releasing hormone analogs (GnRHa) are the most effective therapy in CPP. Drug-induced hypersensitivity vasculitis is an inflammation of blood vessels, which may be due to the use of a number of pharmacologic agents. This case report describes drug-induced vasculitis in a girl being treated with Decapeptyl. A 7.25 year-old girl was admitted to Pediatric Endocrinology outpatients with premature breast development. She was diagnosed with CPP on the basis of physical examination and laboratory findings and tripoteline acetate (Decapeptyl®) treatment was initiated. She experienced multiple widespread skin rashes and mild abdominal pain with high temperature eight hours after the second dose of Decapeptyl. She was admitted to hospital with the diagnosis of drug-induced vasculitis and a single dose of intravenous methyl-prednisolone (1 mg/kg) and oral cetirizine was given. Her blood and urine analysis revealed no other organ involvement, other than skin. On the third day, the purpuric lesions began to resolve and had completely disappeared by the sixth day. Her treatment for CPP was switched to Depot Leuprolide acetate and she continued her treatment for two years uneventfully. To the best of our knowledge, this is the first report of a child with CPP experiencing drug-induced vasculitis due to tripotelin injection. Effective treatment may be continued by switching to an alternative gonadotropin releasing hormone analog.

RESUMO

ABSTRACT: Triptorelin is one of the most commonly used gonadotropin-releasing hormone agonists and has been used in the treatment of deep infiltrating endometriosis (DIE). This study aimed to evaluate the efficacy and safety of up to 24 weeks of triptorelin treatment after conservative surgery for DIE.This prospective, non-interventional study was performed in 18 tertiary hospitals in China. Premenopausal women aged ≥18 years treated with triptorelin 3.75 mg once every 28 days for up to 24 weeks after conservative surgery for DIE were included. Endometriosis symptoms were assessed, using a visual analogue scale (0-10 cm) or numerical range (0-10), at baseline (pre-surgery) and routine visits 3, 6, 9, 12, 18, and 24 months after surgery. Changes in symptom intensity over time were primary outcome measures.A total of 384 women (mean [standard deviation] age, 33.4 [6.2] years) were analyzed. Scores for all symptoms (pelvic pain, dysmenorrhea, ovulation pain, dyspareunia, menorrhagia, metrorrhagia, and gastrointestinal and urinary symptoms) assessed decreased from baseline over 24 months. Cumulative improvement rates in pelvic pain, dysmenorrhoa, ovulation pain, and dyspareunia were 74.4%, 83.6%, 55.1%, and 66.9%, respectively. The 24-month cumulative recurrence rate (≥1 symptom) was 22.2%. The risk of symptom recurrence was higher in patients with ≥2 versus 1 lesion (odds ratio [OR] 2.539; 95% CI: 1.458-4.423; P = .001) and patients with moderate (OR 5.733; 95% CI: 1.623-20.248; P = .007) or severe (OR 8.259; 95% CI: 2.449-27.851; P = .001) pain versus none/mild pain. Triptorelin was well tolerated without serious adverse events.Triptorelin after conservative surgery for DIE improved symptoms over 24 months of follow up. The recurrence rate of symptoms was low and triptorelin was generally well tolerated.Trial registration number: ClinicalTrials.gov, NCT01942369.

RESUMO

Desde hace varias décadas, los análogos de la hormona liberadora de gonadotrofinas (aGnRH) son el tratamiento de elección en la pubertad precoz central (PPC) en niñas y en niños. Causan una inhibición del eje hipotálamo-hipófiso-gonadal, disminuyen la secreción de gonadotrofinas, estradiol y testosterona; como consecuencia, producen una regresión de los caracteres sexuales secundarios durante el tratamiento. En los últimos años, estos análogos también se utilizan en adolescentes transgénero, en adolescentes y adultas jóvenes con enfermedades oncológicas, en algunas situaciones muy particulares en niños y niñas con talla baja, y en pacientes con trastornos del neurodesarrollo. En Argentina, los más utilizados son el acetato de triptorelina y el acetato de leuprolide en sus formas de depósito. Estos medicamentos han demostrado eficacia y seguridad. El objetivo de esta publicación es realizar una revisión y actualización del uso de los aGnRH en niños, niñas y adolescentes.


For several decades, gonadotropin releasing hormone analogs (GnRHa) are the medical treatment selected for central precocious puberty (CPP) in girls and boys. They generate an inhibition of the hypothalamus-pituitarygonadal axis decreasing LH, FSH, estradiol and testosterone secretion and, in this way, they produce a regression of secondary sexual characters under treatment. In the last years, these analogs are also used in trans adolescents, in adolescents and young adults with oncological diseases, in some very particular situations in children with short stature and in patients with neurodevelopmental disorders. In Argentina the most commonly used formulations are triptorelin and leuprolide acetate depot forms. These analogs have proven both their efficacy and their safety. The aim of this paper is to review and update about the use of GnRHa in children and adolescents.

RESUMO

BACKGROUND: The prevalence of precocious puberty is increasing. Obesity has been demonstrated to be associated with changes in the adipokine profile and incidence of early puberty in girls. This study assessed the pubertal signs, the levels of adiponectin, resistin, and tumor necrosis factor-alpha (TNF-α) after 12 weeks of combined exercise and 4 weeks of detraining in overweight and obese girls with precocious puberty. METHODS: Thirty overweight and obese girls (aged 7-9) with precocious puberty, who had received Triptorelin, were randomly divided into two groups (15 exercise and 15 control). Initially, serum levels of adiponectin, resistin, TNF-α, luteinising hormone (LH), and follicle-stimulating hormone (FSH) and the signs of puberty progression (bone age, uterine length, and ovarian volume) were measured. The exercise group performed 60 min of combined (aerobic and resistance) exercise three times/week for 12 weeks. The control group did not receive any exercise. 48 h after the last training session and after 4 weeks of detraining, all research variables were measured (also in the control group). The statistical method used for data analysis was repeated measures ANOVA. RESULTS: In the exercise group, adiponectin significantly increased and resistin significantly decreased after 12 weeks. After 4 weeks of detraining, adiponectin significantly decreased, but resistin significantly increased. TNF-α levels did not change significantly during the study. There was no significant difference in all of the factors in the control group. Throughout the 16-week study period, the rate of puberty and LH significantly decreased in both exercise and control groups, but FSH, LH/FSH and ovarian volume significantly decreased in the exercise group alone (P<0.05). CONCLUSIONS: Combined exercise increased adiponectin and decreased resistin and the rate of puberty. However, after 4 weeks of detraining, these effects diminished but did not disappear.

RESUMO

BACKGROUND: Triptorelin depot is largely used to treat central precocious puberty (CPP) in children, and a 3-month depot has been introduced. However, data about the 3-month gonadotropin-releasing hormone use for treatment of CPP in Korean girls are not available. This study was conducted to compare the efficacy of a triptorelin 11.25 mg 3-month depot with that of a 3.75 mg 1-month depot in suppressing pubertal development for the treatment of CPP. METHODS: A retrospective study, including 106 girls with CPP treated with triptorelin, was conducted. Fifty patients were treated with a triptorelin 3-month depot, and 56 were treated with a triptorelin 1-month depot. Serum luteinizing hormone (LH), follicle-stimulating hormone, and estradiol levels were analysed every 6 months after the visit. The height and bone age of each patient was evaluated at the beginning of treatment, after 6 months, and one year after therapy. RESULTS: The baseline characteristics of the girls treated with a 3-month depot were similar to those of the girls treated with a 1-month depot. A suppressed levels of LH to the triptorelin injection (serum LH < 2.5 IU/L) at 6 months was seen in 90.0% and 98.2% of the girls treated with the 3-month and 1-month depots, respectively (P = 0.160). After 1 year of treatment, a suppressed levels of LH was seen in 93.5% and 100% of the girls treated with the 3-month and 1-month depots, respectively (P = 0.226). Height velocity showed no significant difference between the two groups. Degree of bone age advancement decreased from 1.22 ± 0.07 and 1.22 ± 0.08 years at baseline (P = 0.914) to 1.16 ± 0.07 and 1.17 ± 0.08 in the girls treated with the 3-month and 1-month depots after 1 year, respectively (P = 0.481). CONCLUSION: This study showed that the efficacy of long-acting triptorelin 3-month was comparable to 1-month depot regarding hormonal suppression and inhibition of bone maturation. The triptorelin 11.25 mg 3-month depot is an effective treatment for girls with CPP.

RESUMO

BACKGROUND: A consensus has been reached on the preferred primary outcome of all infertility treatment trials, which is the cumulative live birth rate (CLBR). Some recent randomized controlled trials (RCTs) and retrospective studies have compared the effectiveness of GnRH-antagonist and GnRH-agonist protocols but showed inconsistent results. Studies commonly used conservative estimates and optimal estimates to described the CLBR of one incomplete assisted reproductive technology (ART) cycle and there are not many previous studies with data of the complete cycle to compare CLBRs in GnRH-antagonist versus GnRH-agonist protocols. METHODS: A total of 18,853 patients have completed their first IVF cycle including fresh and subsequent frozen-thawed cycles during 2016-2019, 16,827 patients were treated with GnRH-a long and 2026 patients with GnRH-ant protocol. Multivariable logistic analysis was used to evaluate the difference of GnRH-a and GnRH-ant protocol in relation to CLBR. Utilized Propensity Score Matching(PSM) for sampling by up to 1:1 nearest neighbor matching to adjust the numerical difference and balance the confounders between groups. RESULTS: Before PSM, significant differences were observed in baseline characteristics and the CLBR was 50.91% in the GnRH-a and 33.42% in the GnRH-ant (OR = 2.07; 95%CI: 1.88-2.28; P < 0.001). Stratified analysis showed the CLBR of GnRH-ant was lower than GnRH-a in suboptimal responders(46.89 vs 27.42%, OR = 2.34, 95%CI = 1.99-2.74; P < 0.001) and no differences of CLBR were observed in other patients between protocols. After adjusting for potential confounders, multivariable logistic analysis found the CLBR of GnRH-ant group was lower than that of GnRH-a group (OR = 2.11, 95%CI:1.69-2.63, P < 0.001). After PSM balenced the confounders between groups, the CLBR of GnRH-a group was higher than that of GnRH-ant group in suboptimal responders((38.61 vs 28.22%, OR = 1.60, 95%CI = 1.28-1.99; P < 0.001) and the normal fertilization rate and number of available embryo in GnRH-a were higher than these of GnRH-ant groups in suboptimal responders (77.39 vs 75.22%; 2.86 ± 1.26 vs 2.61 ± 1.22; P < 0.05). No significant difference was observed in other patients between different protocols. CONCLUSIONS: It is crucial to optimize the utilization of protocols in different ovarian response patients and reconsider the field of application of GnRH-ant protocols in China.

RESUMO

CONTEXT: Although gonadotropin-releasing hormone stimulation test (GnRHST) is the gold standard in diagnosing central precocious puberty (CPP), it is invasive, expensive, and time-consuming, requiring multiple blood samples to measure gonadotropin levels. OBJECTIVE: We evaluated whether urinary hormones could be potential biomarkers for prepuberty or postpuberty, aiming to simplify the current diagnosis and prognosis procedure. METHODS: We performed a cross-sectional study of a total of 355 girls with CPP in National Clinical Research Center for Child Health in China, including 258 girls with positive and 97 girls with negative results from GnRHST. Twenty patients received GnRH analogue (GnRHa) treatment and completed a 6-month follow up. We measured luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, prolactin, progesterone, testosterone, and human chorionic gonadotropin in the first morning voided urine samples. RESULTS: Their urinary LH levels and the ratios of LH to FSH increased significantly with the advancement in Tanner stages. uLH levels were positively associated with basal and peak LH levels in the serum after GnRH stimulation. A cutoff value of 1.74 IU/L for uLH reached a sensitivity of 69.4% and a specificity of 75.3% in predicting a positive GnRHST result. For the combined threshold (uLH ≥ 1.74 + uLH-to-uFSH ratio > 0.4), the specificity reached 86.6%. After 3 months of GnRHa therapy, the uLH and uFSH levels decreased accordingly. CONCLUSION: uLH could be a reliable biomarker for initial CPP diagnosis and screening; uLH could also be an effective marker for evaluating the efficacy of clinical treatment.

RESUMO

Objective: This study aimed to compare the ultra-long gonadotropin-releasing hormone agonist (GnRH-a) protocol and the long GnRH-a protocol during in vitro fertilization (IVF) or intracytoplasmic sperm (ICSI) treatment on fertility outcomes in women with adenomyosis. Materials and Methods: This study was a retrospective cohort study. From January 2011 to May 2018, a total of 371 fresh IVF/ICSI cycles were included. Among the cycles included, 237 cycles of 212 women underwent the ultra-long GnRH-a protocol, while 134 cycles of 116 women underwent the long GnRH-a protocol. The rates of implantation, clinical pregnancy per embryo transfer, live birth, and early miscarriage were estimated between the compared protocols. Results: In the study, the early miscarriage rate in women undergoing the ultra-long GnRH-a protocol was significantly lower than those undergoing the long GnRH-a protocol (12.0% versus 26.5%, p = 0.045), whereas the differences in the rates of biochemical pregnancy, implantation, clinical pregnancy, and live birth in women between the two groups showed no statistical significance. The pregnancy outcomes were also sub-analyzed according to the adenomyotic region (diffuse and focal). As for diffuse adenomyosis, the rates of clinical pregnancy and live birth in women undergoing the ultra-long GnRH-a protocol were significantly higher than those undergoing the long GnRH-a protocol (55.3% versus 37.9%, p = 0.025; 43.4% versus 25.9%, p = 0.019, respectively). However, pregnancy outcomes showed no difference between the two protocols in women with focal adenomyosis. Conclusions: The ultra-long GnRH-a protocol during IVF/ICSI improves pregnancy outcomes in women with adenomyosis, especially in women with diffuse adenomyosis when compared with the long GnRH-a protocol.

RESUMO

Duplication of the pituitary gland (DPG)-plus syndrome is a very rare developmental disorder with few cases described in the literature and characterized by multiple midline and central nervous system malformations. The hypothalamus and hypophysis involvement may be clinically associated with endocrine abnormalities. A 5.9-year-old female child was admitted to our Clinic for premature thelarche and acceleration of growth. DPG-plus syndrome with paired infundibula and pituitary glands was diagnosed after birth, when she appeared small for gestational age and she presented with lingual hypoplasia, cleft palate, right choanal stenosis, nasopharyngeal teratoma, and facial dysmorphisms. Neuroimaging revealed a duplication of the infundibula, the pituitary gland, and the dens of the epistropheus despite surgical removal of a rhino-pharyngeal mass performed at the age of two months. An array-CGH revealed a 2p12 deletion. At our evaluation, bone age assessment resulted advanced and initial pubertal activation was confirmed by Gonadotropin-Releasing Hormone stimulation test. Hormonal suppression treatment was started with satisfactory results. This case shows that DPG-plus syndrome must be considered in presence of midline and craniofacial malformations and endocrinological evaluations should be performed for the prompt and appropriate management of pubertal anomalies.

RESUMO

BACKGROUND: The recurrence of deep infiltrating endometriosis (DIE) after its surgical excision is a big problem: postoperative treatment is crucial. OBJECTIVE: To compare two postoperative treatments: Dienogest and GnRH agonists. DESIGN: Prospective Randomized Controlled Trial (RCT). PATIENTS: 146 women submitted to laparoscopic eradication of DIE with bowel and parametrial surgery. INTERVENTIONS: Patients were randomized into two groups. Group A (n = 81) received Triptorelin or Leuprorelin 3.75 mg every 4 weeks for 6 months. Group B (n = 65) received Dienogest 2 mg/day for at least 6 months. A first interview made after six months valued compliance to therapy, treatment tolerability, pain improvement, and side effects. A second interview at 30 ± 6 months valued pain relapse, imaging relapse, and pregnancy rate. MAIN OUTCOMES: The primary outcome was to demonstrate the non-inferiority of Dienogest about the reduction in pain recurrence. Secondary outcomes were differences in terms of treatment tolerability, side effects, imaging relapse rate, and pregnancy rate. RESULTS: Both Dienogest and GnRH agonists were associated with a highly significant reduction of pain at 6 and 30 months, without any significant difference (p < .001). About treatment tolerability, a more satisfactory profile was reported with Dienogest (p = .026). No difference in terms of clinical relapse, imaging relapse, and live births was found. CONCLUSIONS: Dienogest has proven to be as effective as GnRH agonists in preventing recurrence of DIE and associated pelvic pain after surgery. Also, it is better tolerated by patients.

RESUMO

The aim of this study is to evaluate the effect of GnRH agonist or GnRH antagonist therapy on bleomycin-administered rats by examining ovarian follicle counts and AMH levels. A total of 30 female Wistar albino rats aged 4-6 months were randomly divided into 4 groups. First, an intramuscular injection of bleomycin (30 mg/m2) was administered to all except the control group on the 1st, 8th and 15th days. The control group (Group I) was administered 0.1 mL intramuscular saline on those days. The bleomycin group (Group II) was followed up without any further treatment. The bleomycin + GnRH agonist group (Group III) was administered subcutaneous GnRH agonist triptorelin (1 mg/kg) at the same time as the bleomycin injections. The bleomycin + GnRH antagonist group (Group IV) was administered 1 mg/kg cetrorelix acetate subcutaneously, concurrently with the bleomycin. Although AMH levels were lower in the bleomycin group than in all the other groups, there was no statistically significant difference between the groups in terms of AMH levels (p > .05). In the bleomycin + cetrorelix acetate and bleomycin + triptorelin groups, significantly higher primordial, secondary and tertiary follicle counts were determined compared to the bleomycin group (p < .001). In conclusion the harmful effects of bleomycin on ovarian reserve can be reduced by the simultaneous administration of GnRH agonist or GnRH antagonist.

RESUMO

OBJECTIVE: To compare the live birth rate and cost effectiveness of artificial cycle-prepared frozen embryo transfer (AC-FET) with or without GnRH agonist (GnRH-a) pretreatment for women with polycystic ovary syndrome (PCOS). DESIGN: Open-label, randomised, controlled trial. SETTING: Reproductive centre of a university-affiliated hospital. SAMPLE: A total of 343 women with PCOS, aged 24-40 years, scheduled for AC-FET and receiving no more than two blastocysts. METHODS: The pretreatment group (n = 172) received GnRH-a pretreatment and the control group (n = 171) did not. Analysis followed the intention-to-treat (ITT) principle. MAIN OUTCOME MEASURES: The primary outcome measure was live birth rate. Secondary outcome measures included clinical pregnancy rate, implantation rate, early pregnancy loss rate and direct treatment costs per FET cycle. RESULTS: Among the 343 women randomised, 330 (96.2%) underwent embryo transfer and 328 (95.6%) completed the protocols. Live birth rate according to ITT did not differ between the pretreatment and control groups [85/172 (49.4%) versus 92/171 (53.8%), absolute rate difference -4.4%, 95% CI -10.8% to 2.0% (P = 0.45). Implantation rate, clinical pregnancy rate and early pregnancy loss rate also did not differ between groups, but median direct cost per FET cycle was significantly higher in the pretreatment group (7799.2 versus 4438.9 RMB, OR = 1.9, 95%CI 1.2-3.4, P < 0.001). Median direct cost per live birth was also significantly higher in the pretreatment group (15663.1 versus 8189.9 RMB, odds ratio [OR] = 1.9, 95% CI 1.2-3.8, P < 0.001). CONCLUSIONS: Pretreatment with GnRH-a does not improve pregnancy outcomes for women with PCOS receiving AC-FET, but significantly increases patient cost. TWEETABLE ABSTRACT: For women with PCOS, artificial cycle-prepared FET with GnRH agonist pretreatment provides no pregnancy outcome benefit but incurs higher cost.

RESUMO

PROBLEM: Interleukin 8 (IL-8), vascular endothelial growth factor A (VEGFA), its receptors 1 (VEGFR1) and 2 (VEGFR2) are associated with ovarian hyperstimulation syndrome (OHSS) pathophysiological mechanisms. The aim of this study was to evaluate the concentrations of these cytokines depending on the way of ovulation triggering. METHOD OF STUDY: A total of 51 high-responder patients underwent IVF program and received gonadotropin-releasing hormone agonists (GnRHa) trigger + 1500 IU human chorionic gonadotropin (hCG) support on the oocyte pick-up (OPU) day (group I), dual trigger (GnRHa + 1500 IU hCG; group II), or hCG trigger 10,000 IU (group III) for the final oocyte maturation. The concentrations of cytokines were evaluated in serum by the enzyme-linked immunosorbent assay kit. RESULT(S): VEGFR2 levels were significantly lower in groups I and II than in group III in serum on the OPU (I vs. III, p = .0456; II vs. III, p = .0122) and OPU + 5 day (I vs. III, p = .0004; II vs. III, p = .0082). VEGFA levels were lower in group I than in group III (p = .0298) on the OPU day, however, were similar in all groups on the OPU + 5 day. CONCLUSION(S): A small dose of hCG elicits similar concentrations of VEGFA to a full dose of hCG; however, GnRHa triggering reduces the concentrations of VEGFR2, which could lead to the OHSS prevention.
