RESUMEN

OBJECTIVES: To observe the therapeutic efficacy of high-intensity focused ultrasound (HIFU) combined with different pharmacological treatments for adenomyosis. MATERIALS AND METHODS: A total of 126 patients with adenomyosis who underwent HIFU combined with pharmacological treatment were retrospectively reviewed. Patients were treated with either dienogest (DNG) (Group A, N = 38) or GnRH-a (Group B, N = 88) for three months after HIFU, and received levonorgestrel-releasing intrauterine systems (LNG-IUS) at the end of the third month. Visual Analog Scale (VAS) and Pictorial Blood Loss Assessment Chart (PBAC) scores were used for evaluating symptom improvement. RESULTS: After propensity score matching (1:2), 38 patients were included in Group A and 76 in Group B. All patients showed significant improvement in VAS and PBAC scores after HIFU, but the PBAC score of Group A was significantly higher than that of patients in Group B at 18 months [11.50 (1.00, 29.50) vs. 0.00 (0.00, 16.50), p < 0.01] and 24 months [4.00 (0.25, 27.75) vs. 0.00 (0.00, 12.75), p = 0.04] after HIFU. Furthermore, patients in Group B had a greater uterine volume reduction at 24 months after HIFU than that of patients in Group A [51.00 (27.00, 62.00) vs. 30.00 (17.00, 42.75, p = 0.02)]. However, the adverse effects in Group A were lower than those in Group B [7 (15.79) vs. 35 (46.05), p < 0.01]. No significant difference was observed in the recurrence rate between the two groups. CONCLUSIONS: HIFU combined with DNG and LNG-IUS is a safe and effective treatment for patients with adenomyosis.

RESUMEN

Managing breast cancer in premenopausal women poses unique challenges due to its considerable effect on both morbidity and mortality. Goserelin, a gonadotropin-releasing hormone agonist, has emerged among the various modalities as a preferred option for ovarian function suppression, owing to its efficacy in reducing ovarian estrogen production in premenopausal women with hormone receptor-positive breast cancer. Recent studies have affirmed the efficacy and safety of long-acting (LA) goserelin 10.8 mg every 12 weeks, offering comparable outcomes to monthly injections. This flexibility enables personalized treatment approaches, potentially enhancing patient satisfaction. Off-label utilization of goserelin LA surged during the coronavirus disease pandemic, prompting initiatives to broaden its use for breast cancer treatment. Switching to goserelin LA can streamline treatment, boost adherence, and optimize resource utilization. With the recent approval of goserelin 10.8 mg LA by Health Canada on 6 May 2024, for use in breast cancer, Canada is the latest to join over 60 countries worldwide to expand the accepted indications for goserelin LA and ensure its availability to potentially enhance healthcare delivery, patient care, and breast cancer outcomes. Goserelin LA offers premenopausal patients a means to more effectively manage the constraints imposed by breast cancer treatment and its impact on survivorship.

RESUMEN

PURPOSE: To provide a method for the differential diagnosis of Robert's uterus with adenomyosis, a rare uterine malformation, and determine the best course of treatment. METHODS: A patient who had Robert's uterus with adenomyosis was admitted to our hospital in December 2022. We analyzed and summarized her case . RESULTS: Our patient complained of progressively worsening primary dysmenorrhea over the course of 3 years and lower abdominal pain lasting for 2 days. Her carbohydrate antigen 125 (CA125) level was 372.10 U/mL. Examinations conducted by several hospitals indicated that she had a single-horned uterus and a residual horned uterus, and our hospital's examination identified Robert's uterus. This malformation was corrected by open abdominal surgery. For the procedure, pelvic adhesions were first isolated, after which the closed uterine cavity and adenomyosis were resected. Subsequently, the left ovarian endometriosis cyst was resected and right tubal ligation was performed. After surgery, three injections of gonadotropin-releasing hormone A (GnRH-A) were administered, which lowered the patient's CA125 level to 14 U/mL and normalized her condition. CONCLUSION: We pioneered a new therapeutic approach for the treatment of Robert's uterus with adenomyosis. Some valuable references are provided for clinical practice.

RESUMEN

Background: Obesity is one of the most prevalent and perilous health affairs. Male obesity-associated secondary hypogonadism (MOSH) is one of many of its complexities, which is mounting in parallel with the aggravation of obesity. Magnetic nanoparticles seem to be an advanced favorable trend in multiple biomedical fields. Aim: In this study, we explore the therapeutic effects of superparamagnetic iron oxide nanoparticles (SPIONs) coated with carboxymethyl cellulose (CMC) on an obese male rat model with MOSH syndrome, comparing their impacts with a well-known anti-obesity medication (Orlistat). Methods: 42 male albino rats split into 7 equal groups: 1-negative control: nonobese, untreated; 35 rats fed the high fat-high fructose (HFHF) diet for a period of 12 weeks. Obese rats splitted into 6 equal groups; 2-positive control: obese untreated; 3-obese given Orlistat (30 mg/kg); 4-obese given CMC-SPIONs (25 mgFe/kg); 5-obese given CMC-SPIONs (50 mgFe/kg); 6-obese given CMC-SPIONs(25 mgFe/kg) + Orlistat (30 mg/kg), 7-obese given CMC-SPIONs (50 mgFe/kg) + Orlistat (30 mg/kg); all treatments given orally for 4 weeks. During sacrifice, blood serum and sectioned hypothalamic, pituitary, testicular, and adipose tissues were collected for biochemical and biomolecular assessments. Results: The HFHF diet for 12 weeks resulted in a significant upsurge in body weight, body mass index, serum fasting glucose, insulin resistance, TAG, total cholesterol, and LDL-c; HDL-c was dropped. Serum FSH, LH, and testosterone values declined. A significant disorder in expression levels of genes regulating the hypothalamic-pituitary-testicular-axis pathway. Hypothalamic GnRH, Kisspeptin-1, Kisspeptin-r1, and Adipo-R1 values declined. GnIH and Leptin-R1 values raised up. Pituitary GnRH-R values declined. Testicular tissue STAR, HSD17B3, and CYP19A1 values declined. Adipose tissue adiponectin declined, while leptin raised up. CMC-SPIONs 25-50 mg could modulate the deranged biochemical parameters and correct the deranged expression levels of all previous genes. Co-treatments revealed highly synergistic effects on all parameters. Overall, CMC-SPIONs have significant efficiency whether alone or with Orlisat in limiting obesity and consequence subfertility. Conclusion: CMC-SPIONs act as an incoming promising contender for obesity and MOSH disorders management, and need more studies on their mechanisms.

RESUMEN

BACKGROUND: Diminished ovarian reserve (DOR) is one of the obstacles affecting the reproductive outcomes of patients receiving assisted reproductive therapy. The purpose of this study was to investigate whether dual trigger, including gonadotropin-releasing hormone agonist (GnRHa) and human chorionic gonadotropin (hCG), can improve pregnancy outcomes in patients with DOR undergoing in vitro fertilization (IVF) cycles using mild stimulation protocols. METHODS: A total of 734 patients with DOR were included in this retrospective study. Patients were divided into a recombinant hCG trigger group and a dual trigger group (hCG combined with GnRHa) according to the different trigger drugs used. The main outcome measures included the number of oocytes retrieved, the fertilization rate, the number of transferable embryos, the implantation rate, the clinical pregnancy rate, the miscarriage rate, the live birth rate (LBR), and the cumulative live birth rate (CLBR). Generalized linear model and logistic regression analyses were performed for confounding factors. RESULTS: There were 337 cycles with a single hCG trigger and 397 cycles with dual trigger. The dual trigger group demonstrated significantly higher numbers of retrieved oocytes [3.60 vs. 2.39, adjusted ß = 0.538 (0.221-0.855)], fertilized oocytes [2.55 vs. 1.94, adjusted ß = 0.277 (0.031-0.523)] and transferable embryos [1.22 vs. 0.95, adjusted ß = 0.162 (-0.005-0.329)] than did the hCG trigger group, whereas no significant difference in the fertilization rate was observed between the two groups. Moreover, the embryo transfer cancellation rate (35.5% vs. 43.9%) was obviously lower in the dual trigger group. Among the fresh embryo transfer cycles, the implantation rate, clinical pregnancy rate, miscarriage rate and live birth rate were similar between the two groups. After controlling for potential confounding variables, the trigger method was identified as an independent factor affecting the number of oocytes retrieved but had no significant impact on the CLBR. CONCLUSIONS: Dual triggering of final oocyte maturation with hCG combined with GnRHa can significantly increase the number of oocytes retrieved in patients with DOR but has no improvement effect on the implantation rate, clinical pregnancy rate or LBR of fresh cycles or on the CLBR.

RESUMEN

Background and Objectives: The objective of this study was to evaluate the impact of adjuvant letrozole administration during ovarian stimulation using the gonadotropin-releasing hormone (GnRH) antagonist protocol on treatment outcomes in women categorized into POSEIDON groups 3 and 4. Materials and Methods: This retrospective cohort study analyzed data from patients classified into POSEIDON groups 3 and 4 who underwent fresh embryo transfer subsequent to intracytoplasmic sperm injection following a GnRH antagonist stimulation protocol between January 2017 and December 2021. Patients were divided into two groups: the GnRH-LZ group, who received letrozole at a dosage of 5 mg/day for five consecutive days, and the GnRH-ant group, who did not receive adjuvant letrozole. The primary outcome measure of the study was a comparative analysis of live birth rates between the two groups. Results: A total of 449 patients were deemed suitable for final analysis and were allocated into two groups: 281 patients in the GnRH-ant group and 168 patients in the GnRH-LZ group. Live birth rates were found to be comparable in both groups (11% vs. 9%, p = 0.497). Letrozole administration significantly reduced the total amount of gonadotropins required (2606.2 ± 1284.5 vs. 3097.8 ± 1073.3, p < 0.001), the duration of ovarian stimulation (11.2 ± 3.9 vs. 10.2 ± 3, p = 0.005), and the serum peak estradiol concentration (901.4 ± 599.6 vs. 463.8 ± 312.3, p < 0.001). Conclusions: Adjuvant letrozole administration did not demonstrate a significant impact on live birth rates among women categorized into POSEIDON groups 3 and 4. However, this approach may offer potential cost reductions by diminishing the necessity for exogenous gonadotropins and shortening the duration of ovarian stimulation.

RESUMEN

INTRODUCTION: The purpose of the present meta-analysis was to systematically evaluate the effect of GnRHa treatment on the BMI of children with precocious puberty after GnRHa treatment as compared to before, and to analyze the effect of GnRHa treatment on the body composition of children with precocious puberty at different BMIs by classifying into normal body mass, overweight, and obese groups according to BMI at the time of initial diagnosis. CONTENT: A meta-analysis was performed using Stata 12.0 software by searching PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP database), and Wan fang database for relevant literature on standard deviation score of body mass index (BMI-SDS) after GnRHa treatment as compared to before in children with precocious puberty. SUMMARY: A total of eight studies were included with a total sample size of 715 cases, and the results of meta-analysis showed that BMI-SDS increased in children with precocious puberty after GnRHa treatment as compared to before starting [(weighted mean difference (WMD)=0.23, 95 % CI: 0.14-0.33, p=0.000)] and also increased in children with normal body mass [(WMD=0.37, 95 % CI: 0.28-0.46, p=0.000)], and there was no significant change in BMI-SDS in children in the overweight or obese group [(WMD=0.01, 95 % CI: -0.08-0.10, p=0.775)]. OUTLOOK: Overall, there was an observed increase in BMI-SDS at the conclusion of GnRHa treatment in children with precocious puberty. Additionally, it was found that the effect of GnRHa treatment on body composition varied among children with different BMI status. Clinicians should emphasize the promotion of a healthy lifestyle and personalized dietary management for children.

RESUMEN

OBJECTIVE: This trial was to investigate the effect of different treatment methods on the clinical efficacy and fertility outcome of patients with adenomyosis. METHODS: In total, 140 patients with adenomyosis were evenly and randomly allocated into group A (laparoscopic surgery), group B (laparoscopic surgery combined with gonadotropin-releasing hormone analogs [GnRH-a]), group C (ultrasound-guided percutaneous radiofrequency ablation), and group D (ultrasound-guided percutaneous radiofrequency ablation combined with GnRH-a). On the 3rd day after surgery, patients in group B and group D were subcutaneously injected with GnRH-a (Leuprorelin Acetate SR for Injection) at 3.75 mg/time, once every 4 weeks, for a total of 3 months. The therapeutic effects of the 4 groups were compared, including menstrual volume, dysmenorrhea score, uterine volume, clinical efficacy, luteinizing hormone (LH), estradiol (E2), and follicle-stimulating hormone (FSH) levels, CA125 levels, recurrence, pregnancy status, and pregnancy outcomes. RESULTS: After treatment, the menstrual volume of 4 groups was lowered, dysmenorrhea, Visual Analog Scale (VAS) score, LH, FSH, E2, and CA125 levels were reduced, and uterine volume was decreased. The menstrual volume, VAS score, levels of LH, FSH, E2, and CA125, and uterine volume were reduced in groups B, C, and D compared with group A, and the decrease was more significant in group D. The total effective rate of group D was 100.00%, which was higher than that of group A (71.43%), group B (80.00%), and group C (82.86%). After one year of drug withdrawal, the recurrence of hypermenorrhea, dysmenorrhea, uterine enlargement, and excessive CA125 in group D was significantly lower than that in groups A, B and C, and the recurrence in groups B and C was significantly lower than that in group A (P < 0.05). Compared with groups A, B, and C, group D had a higher pregnancy rate, natural pregnancy rate, and lower in vitro fertilization-embryo transfer rate (P < 0.05), but showed no significant difference in pregnancy outcomes. CONCLUSION: Ultrasound-guided percutaneous radiofrequency ablation combined with Leuprorelin Acetate is effective in the treatment of adenomyosis, which can effectively relieve clinical symptoms, protect postoperative ovarian function, reduce recurrence rate, alleviate pain, and improve quality of life.

RESUMEN

INTRODUCTION: Uterine fibroids affect 30%-77% of reproductive-age women and are a significant cause of infertility. Surgical myomectomies can restore fertility, but they often have limited and temporary benefits, with postoperative complications such as adhesions negatively impacting fertility. Existing medical therapies, such as oral contraceptives, gonadotropin hormone-releasing hormone (GnRH) analogues and GnRH antagonists, can manage fibroid symptoms but are not fertility friendly. This study addresses the pressing need for non-hormonal, non-surgical treatment options for women with fibroids desiring pregnancy. Previous preclinical and clinical studies have shown that epigallocatechin gallate (EGCG) effectively reduces uterine fibroid size. We hypothesise that EGCG from green tea extract will shrink fibroids, enhance endometrial quality and increase pregnancy likelihood. To investigate this hypothesis, we initiated a National Institute of Child Health and Human Development Confirm-funded trial to assess EGCG's efficacy in treating women with fibroids and unexplained infertility. METHODS AND ANALYSIS: This multicentre, prospective, interventional, randomised, double-blinded clinical trial aims to enrol 200 participants with fibroids and unexplained infertility undergoing intrauterine insemination (IUI). Participants will be randomly assigned in a 3:1 ratio to two groups: green tea extract (1650 mg daily) or a matched placebo, combined with clomiphene citrate-induced ovarian stimulation and timed IUI for up to four cycles. EGCG constitutes approximately 45% of the green tea extract. The primary outcome is the cumulative live birth rate, with secondary outcomes including conception rate, time to conception, miscarriage rate, change in fibroid volume and symptom severity scores and health-related quality of life questionnaire scores. ETHICS AND DISSEMINATION: The FRIEND trial received approval from the Food and Drug adminstration (FDA) (investigational new drug number 150951), the central Institutional Review Board (IRB) at Johns Hopkins University and FRIEND-collaborative site local IRBs. The data will be disseminated at major conferences, published in peer-reviewed journals and support a large-scale clinical trial. TRIAL REGISTRATION NUMBER: NCT05364008.

RESUMEN

Endometriosis is an estrogen-dependent chronic inflammatory disorder involving the placement and growth of endometrial tissue outside the uterine cavity. It is the most common multifactorial disease that affects the life quality of women in reproductive age. Due to its multicomponent nature, early diagnosis of the disease is challenging. Since many genetic, epigenetic alterations and non-genetic factors contribute to the pathology of endometriosis, devising a drug therapy that directly acts on the ectopic tissue is extremely difficult. Endometriosis is a hormone-driven disease with estrogen considered as a primary driver for the development of endometriotic lesions. This study aims to identify biosignatures involved in endometriosis with and without gonadotropin releasing hormone agonists (GnRHa). GnRHa is a short peptide analog of GnRH that causes inhibition of estrogen and androgen synthesis. Microarray based-gene expression profiling was performed on total RNA extracted from endometriotic tissue samples with and without GnRHa-treated patients already published in our previous paper. The untreated group were considered as the control. Genes were then selected for validation by quantitative real-time polymerase chain reaction (qRT-PCR). qRT-PCR analysis confirmed significant downregulation in(p < 0.05) expression of DARC (p = 0.0042), CDH1 (p = 0.0027), CDH5 (p = 0.0283), ATP2A3 (p < 0.001), RGS5 (p = 0.0032), and CD36 (p = 0.0162) in endometriosis patients treated with GnRHa analogs. Although, CTNNAL1 (p = 0.0136) also showed significant results but there was upregulation in their expression levels after GnRHa treatment. Thus, an altered expression of these genes makes them a possible candidate determinant of endometriosis treated with GnRHa.

RESUMEN

Novel gonadotrophin releasing hormone (GnRH) antagonist treatments have recently been developed in combination with hormonal add-back therapy, as an oral treatment option for women suffering from uterine fibroids. Registration trials assessing the GnRH antagonist combination preparations with relugolix, elagolix and linzagolix have assessed treatment efficacy for fibroid-related heavy menstrual blood loss in comparison to placebo. Marketing authorization has been granted by several agencies including those in Europe, the United Kingdom and the United States. While the registration trials report a robust effect on the reduction of heavy menstrual blood loss and improvement in quality of life scores, reticence is advised before widespread prescription. In this review, we demonstrate limitations in the trial data, namely a lack of generalizability due to the restricted study population, the lack of transparency in the distribution of disease-level characteristics limiting the predictability of treatment success in the real-world diverse population, and the absence of any comparison to current alternative treatment methods. Importantly, no clinically meaningful volume reductions were found with GnRH antagonist combination preparations, and long-term safety data, particularly concerning modest but stable bone mineral density decline, need further addressing. Symptoms related to uterine fibroids adversely affect many women's quality of life and effective medical treatments are lacking. However, despite the urgent need for conservative treatments, it is vitally important that novel drugs, like combination oral GnRH antagonists, undergo sufficiently rigorous evaluation of safety, effectiveness and cost-effectiveness in a representative population and are compared with alternative treatment methods before introduction into mainstream clinical practice.

RESUMEN

OBJECTIVES: This study aimed to evaluate the efficacy and safety of 3-month leuprorelin acetate (3-month LA, 11.25 mg) for the treatment of idiopathic central precocious puberty (ICPP) in Chinese girls. METHODS: We conducted a single-center retrospective study in China on 28 girls with ICPP who received at least one year of 3-month LA treatment. Data from anthropometry, biochemistry, bone age (BA), and pelvic ultrasonography were assessed before and every 6 months during medication. RESULTS: At CPP diagnosis, the mean chronological age (CA) was 7.8±0.8 years, with bone age advancement (BA-CA) of 1.5±0.8 years. After treatment initiation, growth velocity decreased significantly from 8.5±1.6 cm/year to 5.8±1.1 cm/year at month 12 (p<0.001). GnRH-stimulated peak LH ≤3IU/L, the primary efficacy criterion, was observed in 27 out of 28 (96.4 %) children at month 3. Basal estradiol <20 pg/mL was achieved by all 28 girls (100 %) at month 6 and remained stable at month 12. Basal follicle-stimulating hormone (FSH) decreased from 4.1±3.5 to 1.7±0.9 (p<0.001), and basal LH was also significantly reduced from 3.3±6.5 to 0.7±0.8 (p=0.035) at month 12. The mean predicted adult height (PAH) at treatment initiation was 152.7±5.8 cm, it increased significantly to 157.5±5.5 cm (p=0.007) after one-year treatment. Pubertal development was slowed in most patients, and in some cases, it was even reversed. Only one patient (3.6 %) reported local intolerance. CONCLUSIONS: Three-month leuprorelin acetate is a safe and effective treatment for suppressing the pituitary-gonadal axis and restoring impaired adult height in Chinese girls.

RESUMEN

OBJECTIVE: To compare the effects of combined gonadotropin and pulsatile gonadotropin-releasing hormone (GnRH) therapy on spermatogenesis in patients with pituitary stalk interruption syndrome (PSIS). METHODS: Male patients with PSIS (N = 119) were retrospectively studied. Patients received pulsatile GnRH therapy (N = 59) were divided into response and poor-response groups based on luteinizing hormone (LH) levels after 1-month treatment with a cutoff value of 1 or 2 IU/L. Participants with gonadotropin therapy were divided into human menopausal gonadotropin (hMG)/human chorionic gonadotropin (hCG) group (N = 60), and patients with pulsatile GnRH therapy were classified into GnRH group (N = 28) with treatment duration ≥6 months. RESULTS: The overall success rates of spermatogenesis for hMG/hCG and GnRH therapy were 51.67% (31/60) vs 33.90% (20/59), respectively. GnRH group required a shorter period to induce spermatogenesis (8 vs 15 months, P = .019). hMG/hCG group had higher median total testosterone than GnRH group [2.16, interquartile range(IQR) 1.06-4.89 vs 1.31, IQR 0.21-2.26 ng/mL, P = .004]. GnRH therapy had a beneficial effect on spermatogenesis compared to hMG/hCG therapy (hazard ratio 1.97, 95% confidence interval 1.08-3.57, P = .026). In patients with pulsatile GnRH therapy, compared with the poor-response group, the response group had a higher successful spermatogenesis rate (5.00% vs 48.72%, P = .002) and higher median basal total testosterone (0.00, IQR 0.00-0.03 vs 0.04, IQR 0.00-0.16 ng/mL, P = .026) with LH = 1 IU/L as the cutoff value after 1-month pulsatile GnRH therapy. CONCLUSIONS: Pulsatile GnRH therapy was superior to hMG/hCG therapy for spermatogenesis in patients with PSIS. Earlier spermatogenesis and higher concentrations of sperm could be obtained in the GnRH group if patients received therapy over 6 months.

RESUMEN

Prostate cancer is the most common malignancy in men, mostly affecting older men who harbor an increased prevalence of cardiovascular disease and metabolic syndrome. Androgen deprivation therapy (ADT), the standard therapy for various stages of prostate cancer, further increases the risk for cardiovascular disease and for metabolic syndrome. Therefore, screening for cardiovascular risk factors should be performed prior to the initiation of ADT, and, if necessary, cardiological evaluation and interdisciplinary management should be provided during and after completion of ADT. Moreover, the use of a gonadotropin-releasing hormone (GnRH) antagonist may help reduce cardiovascular risk in patients with cardiovascular disease.

RESUMEN

OBJECTIVES: Investigate serum vitamin D (vit D) levels' relation to uterine volume in idiopathic central precocious puberty (ICPP) girls and compare findings with normal peers. METHODS: Analyzed 278 ICPP cases from January 2017 to September 2022 alongside 239 normally developing girls. Collected clinical data and lab markers and performed subgroup analysis based on vit D levels. Correlation and regression analyses were conducted. RESULTS: The ICPP group exhibited elevated uterine volume and lower serum vit D compared to controls (p<0.05). A weak negative correlation was noted between vit D and uterine volume in ICPP (r=-0.193, p=0.004), and no such correlation in controls (r=-0.073, p=0.319). The ICPP vit D deficiency subgroup displayed higher uterine volume than the insufficiency and sufficiency subgroups (p<0.05). Uterine volume in the insufficiency subgroup exceeded the sufficiency subgroup (p<0.05). After adjusting for confounders, lower vit D is linked to increased ICPP uterine volume (non-standardized regression coefficient ß=-25.55, 95 % CI= -46.23, -4.87, p=0.016). A Limited correlation between vit D and uterine volume was seen in girls with normal pubertal timing. CONCLUSIONS: We demonstrated a correlation between vit D and uterine volume in ICPP girls, absent in normal peers. ICPP girls often exhibit lower vit D levels and increased uterine volume. Further research is vital for understanding vit D's role in ICPP pathogenesis and guiding prevention and treatment strategies.

RESUMEN

INTRODUCTION: Endometriosis is an estrogen-dependent disease that gives rise to pelvic pain and infertility. Although estroprogestins and progestins currently stand as the first-line treatments for this condition, demonstrating efficacy in two-thirds of patients, a significant portion of individuals experience only partial relief or symptom recurrence following the cessation of these therapies. The coexistence of superficial, deep endometriosis, and ovarian endometriomas, as three distinct phenotypes with unique pathogenetic and molecular characteristics, may elucidate the current heterogeneous biological response to available therapy. AREAS COVERED: The objective of this review is to furnish the reader with a comprehensive summary pertaining to phase II-III hormonal treatments for endometriosis. EXPERT OPINION: Ongoing research endeavors are directed toward the development of novel hormonal options for this benign yet debilitating disease. Among them, oral GnRH antagonists emerge as a noteworthy option, furnishing rapid therapeutic onset without an initial flare-up; these drugs facilitate partial or complete estrogen suppression, and promote prompt ovarian function recovery upon discontinuation, effectively surmounting the limitations associated with previously employed GnRH agonists. Limited evidence supports the use of selective estrogen and progesterone receptor modulators. Consequently, further extensive clinical research is imperative to garner a more profound understanding of innovative targets for novel hormonal options.

RESUMEN

Central precocious puberty (CPP) refers to early activation of the hypothalamic-pituitary-gonadal (HPG) axis and is manifested by breast development in girls or testicular enlargement in boys before the normal physiological age ranges. CPP can be precipitated by intracranial pathology, exposure to high levels of sex steroids, or environmental risk factors, but most cases are idiopathic. Monogenic causes have also been identified. In this Review, we summarise pathophysiology, risk factors, diagnosis, and management of CPP. Concern for CPP should prompt referral to paediatric endocrinology where diagnosis is confirmed by clinical, biochemical, radiological, and genetic testing. CPP is treated with a gonadotropin-releasing hormone analogue, the primary aims of which are to increase adult height and postpone development of secondary sexual characteristics to an age that is more commensurate with peers. Although long-term outcomes of treatment with gonadotropin-releasing hormone analogues are reassuring, additional research on the psychological effect of CPP is needed.

RESUMEN

BACKGROUND: Diphereline is a Gonadotropin-Releasing Hormone agonist commonly used in patients with breast cancer. This study aimed to compare the efficacy and safety of one-month and three-month Microrelin injections produced by Homa Pharmed Company with three-month Diphereline injections manufactured by IPSEN, France. METHODS: The study was a non-inferiority randomized clinical trial conducted between 2019 and 2023 on premenopausal women candidates for endocrine therapy. The participants were randomly assigned in blocks of six to one of three groups named A (Diphereline 11.25 mg), B (Microrelin 11.25 mg), and C (Microrelin 3.75 mg). The participants' menopausal symptoms, estradiol, and FSH serum levels were recorded in three-month intervals for one year. The efficacy of each medication and its side effects were compared among the three groups by statistical analysis during the one-year follow-up. RESULTS: The study included 133 patients with breast cancer. A decreasing trend in the serum levels of FSH and estradiol and an increasing trend of menopausal symptoms were recorded during the study. No specific side effects leading to drug disruption, hospitalization, or exclusion from the study were observed. Adjusting the effect of study group and time showed no significant changes in estradiol levels between groups B (p = 0.506) and C (p = 0.607) and group A. Also, serum FSH changes between groups B (p = 0.132) and C (p = 0.104) compared to group A were not significant. Moreover, the menopausal symptoms during the one-year follow-up did not significantly increase in group B (p = 0.108) and C (p = 0.113) compared to group A. CONCLUSIONS: It can be concluded that injections of both Microrelin 11.25 mg and 3.75 mg, produced by Homa Pharmed, Iran, are non-inferior in terms of effectiveness and incidence of menopausal symptoms compared to Diphereline, manufactured by IPSEN, France.

RESUMEN

OBJECTIVE: The aim: Evaluation of the effectiveness of hormone therapy before and after surgical treatment in patients with external genital endometriosis (HRT). PATIENTS AND METHODS: Materials and methods: Bibliographic, information-analytical, clinical-instrumental, laboratory, histomorphological methods were used in the work. The sources of information were data from the scientific literature on the topic of the study, modern guidelines, a review of randomized controlled studies. RESULTS: Results: All women involved in the study received hormone therapy before and after surgery for 3-6-9 months: 45.0% - only COCs, 25.0% - courses of a-GnRH drugs; 30.0% - only progestogens. Comparative evaluation of the function of the relapse-free course of UHD using the Kaplan-Meier method showed that when using a-GnRH in patients with UHD, the duration of the relapse-free period is higher than for other groups of drugs: the indicator of the function of maintaining remission before surgical treatment decreases from 100% to 0% during the first 6 months in 89.0%, and during 9 months - in 66.0% of patients. Progression of the disease, after surgery and withdrawal of a-GnRH, with a 3-month course occurred - after 3 months - in 45.0%, with a 6-month course - after 9 months - in 33.0%, with a 9-month course - after 12 months - in 12.0% of people. Thus, the average median of the recurrence-free course was ±11.6 months. CONCLUSION: Conclusions: The most effective hormone therapy in patients with HRT before and after surgical treatment is therapy with drugs of the α-¬HnRH group, courses of at least 6 months.
