Treatment of Endometriosis with the GnRHa Deslorelin and Add-Back Estradiol and Supplementary Testosterone.

BACKGROUND: This randomized, multicenter, open-label clinical trial was intended to generate pilot data on the efficacy and safety of the gonadotropin-releasing hormone agonist (GnRHa) deslorelin (D) with low-dose estradiol ± testosterone (E2 ± T) add-back for endometriosis-related pelvic pain. METHODS: Women with pelvic pain and laparoscopically confirmed endometriosis were treated with a six-month course of daily intranasal D with concurrent administration of either transdermal E2, intranasal E2, or intranasal E2 + T. Efficacy data included evaluation of dyspareunia, dysmenorrhea, pelvic pain, tenderness, and induration. Cognition and quality of life were also assessed. Safety parameters included assessment of endometrial hyperplasia, bone mineral density (BMD), and hot flashes. RESULTS: Endometriosis symptoms and signs scores decreased in all treatment arms from a baseline average of 7.4 to 2.5 after 3 months of treatment and 3.4 after 6 months. BMD changes and incidence of hot flashes were minimal, and no endometrial hyperplasia was observed. Patient-reported outcomes showed significant improvement across multiple domains. CONCLUSIONS: Daily intranasal D with low dose E2 ± T add-back resulted in significant reduction in severity of endometriosis symptoms and signs with few safety signals and minimal hypoestrogenic symptoms that would be expected with the use of a GnRHa alone.

Spontaneous prostatic hematoma: an unusual presentation of prostatic cancer.

Prostatic fluid collection is not uncommon in urological practice. Prostatic abscess is the most frequent finding in this clinical setting. Spontaneous prostatic hematoma is rare, and may be related to prostatic cancer. Every case of prostatic collection must be considered with attention, and further evaluation is needed when the diagnosis is not clear. Here we report the case of a spontaneous prostatic hematoma, which was eventually found to be due to prostatic cancer, describing in detail the clinical features, differential diagnosis and treatment options.

Triptorelin for the treatment of endometriosis.

INTRODUCTION: Over the past 30 years, gonadotropin-releasing hormone agonists (GnRH-a) have been used to induce a hypoestrogenic status in women with endometriosis with the aim to cause an improvement in pain symptoms similar to that observed after menopause. Triptorelin is one of the most commonly used GnRH-a. AREAS COVERED: This review offers an explanation of the mechanism of action, of the pharmacokinetics and pharmacodynamics of triptorelin and gives the readers a complete overview of the studies on the clinical efficacy, tolerability and safety of this agent in patients with endometriosis. EXPERT OPINION: The studies reviewed in the current manuscript demonstrate the efficacy of triptorelin in improving pain symptoms caused by endometriosis. Further, this effect is confirmed by the reduction in the volume of the endometriotic nodules during treatment. Future research should evaluate whether the pre-operative administration of triptorelin prior to surgical excision of endometriomas may be useful in preserving the ovarian reserve.

A biofeedback intervention to control impulsiveness in a severely personality disordered forensic patient.

Impulsiveness in personality disordered forensic patients is associated with poor treatment completion and high risk of re-offending. A biofeedback training protocol, previously found to reduce impulsiveness and improve attention in children with Attention Deficit Hyperactivity Disorder, was used in an initial attempt to reduce impulsiveness in a severely personality disordered man with borderline, antisocial and histrionic features. Electrocortical, behavioural and self-report measures of impulsiveness were taken before and immediately following 6 weeks of biofeedback training and at 3 months follow-up. The patient successfully engaged with the intervention. His self-reports of reduced impulsiveness and improved attention were corroborated by behavioural and electrocortical measures that indicated reduced impulsiveness and better focused attention. Results suggest this intervention might prove useful in improving behavioural and emotional self-regulation in severely personality disordered patients.

Hypothalamic hamartoma.

Hypothalamic hamartomas are rare congenital malformations presenting with central precocious puberty, gelastic epilepsy and developmental retardation. We report a case of an 11-month-old girl with recurring bloody vaginal discharge. Diagnosis of hypothalamic hamartoma was made on the basis of clinical findings and specific features on magnetic resonance imaging of the hypothalamic region.

Randomized trial using gonadotropin-releasing hormone agonist triptorelin for the preservation of ovarian function during (neo)adjuvant chemotherapy for breast cancer.

PURPOSE: Chemotherapy-induced amenorrhea is a serious concern for women undergoing cancer therapy. This prospective randomized trial evaluated the use of gonadotropin-releasing hormone (GnRH) analog triptorelin to preserve ovarian function in women treated with chemotherapy for early-stage breast cancer. PATIENTS AND METHODS: Premenopausal women age 44 years or younger were randomly assigned to receive either triptorelin or no triptorelin during (neo)adjuvant chemotherapy and were further stratified by age (< 35, 35 to 39, > 39 years), estrogen receptor status, and chemotherapy regimen. Objectives included the resumption of menses and serial monitoring of follicle-stimulating hormone (FSH) and inhibin A and B levels. RESULTS: Targeted for 124 patients with a planned 5-year follow-up, the trial was stopped for futility after 49 patients were enrolled (median age, 39 years; range, 21 to 43 years); 47 patients were treated according to assigned groups with four cycles of adriamycin plus cyclophosphamide alone or followed by four cycles of paclitaxel or six cycles of fluorouracil, epirubicin, and cyclophosphamide. Menstruation resumed in 19 (90%) of 21 patients in the control group and in 23 (88%) of 26 in the triptorelin group (P= .36). Menses returned after a median of 5.8 months (range, 1 to 19 months) after completion of chemotherapy in the triptorelin versus 5.0 months (range, 0 to 28 months) in the control arm (P= .58). Two patients (age 26 and 35 years at random assignment) in the control group had spontaneous pregnancies with term deliveries. FSH and inhibin B levels correlated with menstrual status. CONCLUSION: When stratified for age, estrogen receptor status, and treatment regimen, amenorrhea rates on triptorelin were comparable to those seen in the control group.

Effect of the gonadotropin-releasing hormone analogue triptorelin on the occurrence of chemotherapy-induced early menopause in premenopausal women with breast cancer: a randomized trial.

CONTEXT: Premenopausal patients with breast cancer are at high risk of premature ovarian failure induced by systemic treatments, but no standard strategies for preventing this adverse effect are yet available. OBJECTIVE: To determine the effect of the temporary ovarian suppression obtained by administering the gonadotropin-releasing hormone analogue triptorelin during chemotherapy on the incidence of early menopause in young patients with breast cancer undergoing adjuvant or neoadjuvant chemotherapy. DESIGN, SETTING, AND PATIENTS: The PROMISE-GIM6 (Prevention of Menopause Induced by Chemotherapy: A Study in Early Breast Cancer Patients-Gruppo Italiano Mammella 6) study, a parallel, randomized, open-label, phase 3 superiority trial, was conducted at 16 sites in Italy and enrolled 281 patients between October 2003 and January 2008. The patients were premenopausal women with stage I through III breast cancer who were candidates for adjuvant or neoadjuvant chemotherapy. Assuming a 60% rate of early menopause in the group treated with chemotherapy alone, it was estimated that 280 patients had to be enrolled to detect a 20% absolute reduction in early menopause in the group treated with chemotherapy plus triptorelin. The intention-to-treat analysis was performed by including all randomized patients and using imputed values for missing data. INTERVENTIONS: Before beginning chemotherapy, patients were randomly allocated to receive chemotherapy alone or combined with triptorelin. Triptorelin was administered intramuscularly at a dose of 3.75 mg at least 1 week before the start of chemotherapy and then every 4 weeks for the duration of chemotherapy. MAIN OUTCOME MEASURE: Incidence of early menopause (defined as no resumption of menstrual activity and postmenopausal levels of follicle-stimulating hormone and estradiol 1 year after the last cycle of chemotherapy). RESULTS: The clinical and tumor characteristics of the 133 patients randomized to chemotherapy alone and the 148 patients randomized to chemotherapy plus triptorelin were similar. Twelve months after the last cycle of chemotherapy (last follow-up, August 18, 2009), the rate of early menopause was 25.9% in the chemotherapy-alone group and 8.9% in the chemotherapy plus triptorelin group, an absolute difference of -17% (95% confidence interval, -26% to -7.9%; P < .001). The odds ratio for treatment-related early menopause was 0.28 (95% confidence interval, 0.14 to 0.59; P < .001). CONCLUSION: The use of triptorelin-induced temporary ovarian suppression during chemotherapy in premenopausal patients with early-stage breast cancer reduced the occurrence of chemotherapy-induced early menopause.

[Clinical effects of shen-nourishing and menstruation-regulating method combined with triptorelin acetate injection on patient with luteinized unruptured follicle syndrome].

OBJECTIVE: To study the clinical effects of Shen-nourishing and menstruation-regulating method (SNMRM) combined with Triptorelin Acetate Injection (TAI) on patients with luteinized unruptured follicle syndrome (LUFS). METHODS: Sixty-two LUFS patients were randomly assigned to the treatment group and the control group. TAI was given to patients in the control group while SNMRM + TAI was given to those in the treatment group. The ovulation rate and the pregnancy rate were observed in the two groups. RESULTS: The ovulation rate in the treatment group was higher than that in the control group, but without significant difference (85.53% versus 79.07%, P > 0.05). The pregnancy rate was significantly higher in the treatment group than in the control group (56.25% vs 30.00%, P < 0.05). CONCLUSION: Treatment of LUFS by SNMRM + TAI could improve the ovulation rate and the pregnancy rate, indicating that LUFS patients' ovary functions could be improved by using different menstruation regulating methods during different follicular development phases.

The development of a testosterone stimulation test in the Virginia opossum (Didelphis virginiana) and its use in evaluating deslorelin contraception.

The aims of the present study were to examine the variability of testosterone secretion in the Virginia Opossum over a 24 h period and to develop a testosterone stimulation test that would provide an index of the prevailing testosterone biosynthetic capacity of the testes; the latter was used to clinically evaluate the efficacy of a gonadotrophin-releasing hormone agonist contraceptive. Sexually-mature captive opossums (n = 12) located in Africam Safari (Mexico) sampled every 12 h over 24 h consistently showed basal (<0.21 ng mL(-1)) blood testosterone concentrations. Intra-muscular injection of buserelin (2 microg mL(-1)) and human chorionic gonadotrophin (hCG; 1000 IU) resulted in an increase (P < 0.05) of plasma testosterone concentrations with maximal concentrations (3.9 ng mL(-1) and 5.8 ng mL(-1) respectively) occurring 120 min after injection. Plasma testosterone declined relatively rapidly to basal concentrations after 240 min with hCG but remained elevated after the same period of time with buserelin. Male opossums treated with (n = 6) and without (n = 6) a controlled-release deslorelin implant (Suprelorin; 4.7 mg deslorelin) were evaluated over a 10-week period for changes in testosterone secretion (hCG stimulation test) and sperm production (spermatorrhea). At the end of this period, the animals were hemi-castrated and their relative testicular quantitative histology compared. Testosterone concentration decreased over the course of the study in both treated and control animals (P < 0.0001) but there was no apparent effect of deslorelin on testosterone secretion, testicular histology (relative proportions of testicular cell types and seminiferous tubule diameter), or sperm production (presence of sperm in the cauda epididymis or urine).

Complete hormonal blockade versus epirubicin-based chemotherapy in premenopausal, one to three node-positive, and hormone-receptor positive, early breast cancer patients: 7-year follow-up results of French Adjuvant Study Group 06 randomised trial.

BACKGROUND: The purpose of this study was to determine optimal adjuvant therapy between complete hormonal blockade in premenopausal patients with hormone receptor positive breast cancer and one to three positive nodes. PATIENTS AND METHODS: We randomised 333 patients to receive either LHRH agonist (triptorelin 3.75 mg i.m., monthly) plus tamoxifen 30 mg/day for 3 years (TAM-LHRHa, n=164), or fluorouracil 500 mg/m2, epirubicin 50 mg/m2 and cyclophosphamide 500 mg/m2 every 21 days for six cycles, without any hormonal treatment (FEC50, n=169). RESULTS: The 7-year disease-free survival (DFS) was 76% with TAM-LHRHa, and 72% with FEC50 (P=0.13). The 7-year overall survival (OS) was 91% and 88%, respectively (P=0.20). The multivariate analysis confirmed that both treatments were not different for DFS and OS (P=0.83 and P=0.41, respectively). Amenorrhoea occurred in 64% of patients treated with FEC50; it was temporary in 58% of cases after hormonotherapy and in 31% after chemotherapy. CONCLUSION: In intermediate-risk breast cancer, complete hormonal blockade and chemotherapy provided similar outcomes. Hormonal treatment is an alternative to chemotherapy in hormone-sensitive patients, considering the preference of patients in terms of quality of life.

GnRH agonist versus GnRH antagonist in oocyte donation cycles: a prospective randomized study.

BACKGROUND: The specific role of LH in folliculogenesis and oocyte maturation is unclear. GnRH antagonists, when administered in the late follicular phase, induce a sharp decrease in serum LH which may be detrimental for IVF outcome. This study was performed to evaluate whether the replacement of GnRH agonist (triptorelin) by a GnRH antagonist (ganirelix; NV Organon) in oocyte donation cycles has any impact on pregnancy and implantation rates. METHODS: A total of 148 donor IVF cycles was randomly assigned to use either a GnRH antagonist daily administered from the 8th day of stimulation (group I) or a GnRH agonist long protocol (group II) for the ovarian stimulation of their donors. The primary endpoints were the pregnancy and the implantation rates. RESULTS: The clinical pregnancy rate per transfer (39.72%, 29/73 versus 41.33%, 31/75) based on transvaginal scan findings at 7 weeks of gestation, the implantation rate (23.9 versus 25.4%) and the first trimester abortion rate (10.34 versus 12.90%) were similar in the two groups. CONCLUSION: In oocyte donation cycles the replacement of GnRH agonist by a GnRH antagonist appears to have no impact on the pregnancy and implantation rates when its administration starts on day 8 of stimulation.

Neridronate prevents bone loss in patients receiving androgen deprivation therapy for prostate cancer.

UNLABELLED: Today, androgen deprivation therapy is a cornerstone of treatment for advanced prostate cancer, although it presents important complications such as osteoporosis. Neridronate, a relatively new bisphosphonate, is able to prevent bone loss in patients with prostate cancer during androgen ablation. INTRODUCTION: Androgen-deprivation therapy (ADT) is a cornerstone of treatment for advanced prostate cancer. This therapy has iatrogenic complications, such as osteoporosis. The aim of our study was to evaluate the efficacy of neridronate, a relatively new bisphosphonate, to prevent bone loss during androgen ablation. MATERIALS AND METHODS: Forty-eight osteoporotic patients with prostate cancer, treated with 3-month depot triptorelina, were enrolled and randomly assigned to two different treatment groups: group A (n = 24) was treated with a daily calcium and cholecalciferol supplement (500 mg of elemental calcium and 400 IU cholecalciferol), and group B (n = 24) received in addition to the same daily calcium and cholecalciferol supplement, 25 mg of neridronate given intramuscularly every month. All patients also received bicalutamide for 4 weeks. Lumbar and femoral BMD was evaluated by DXA at baseline and after 1 year of therapy; moreover, deoxypyridinoline (DPD) and bone alkaline phosphatase (BALP) were determined at the beginning, midway through, and at the end of the study. RESULTS: After 6 and 12 months, whereas patients treated only with calcium and cholecalciferol (group A) showed a marked bone loss, with increased levels of DPD and BALP compared with baseline values, patients treated also with neridronate (group B) had substantially unchanged levels of these markers. After 1 year of treatment, lumbar and total hip BMD decreased significantly in patients treated only with calcium and cholecalciferol (group A), whereas it did not change significantly at any skeletal site in patients treated also with neridronate (group B). No relevant side effects were recorded during our study. CONCLUSIONS: Neridronate is an effective treatment in preventing bone loss in the hip and lumbar spine in men receiving ADT for prostate cancer.

Bone mass at final height in precocious puberty after gonadotropin-releasing hormone agonist with and without calcium supplementation.

The aim of our longitudinal study was to evaluate bone mass in girls affected by central precocious puberty (CPP) that have reached final height, treated with GnRH agonist triptorelin (GnRHa), with or without calcium supplementation. We studied 48 Caucasian females affected by CPP (age at diagnosis, 7.19 +/- 0.96 yr), randomly assigned to two groups: group A (n = 21) treated with GnRHa and group B (n = 27) treated with GnRHa plus calcium gluconolactate and carbonate (1 g calcium/day in two doses) for at least 2 yr. Auxological parameters (standing height, weight, body mass index) and bone mineral density (BMD) at the lumbar spine [L2-L4, anteroposterior (AP)-BMD; lateral BMD; volumetric (v)BMD)] by dual-energy x-ray absorptiometry were evaluated at the beginning [chronological age (CA), 7.29 +/- 0.91 yr; bone age (BA), 8.80 +/- 1.24 yr] and end of treatment (CA, 11.27 +/- 0.97 yr; BA, 12.35 +/- 0.43 yr) and at final height (CA, 16.17 +/- 1.9 yr; BA, 16.93 +/- 0.98 yr, in each case >15 yr). Total bone mineral content, total BMD, and fat percentage were evaluated at the end of the study period using dual-energy x-ray absorptiometry. Final height was significantly higher than predicted height at diagnosis (159.9 +/- 6.3 cm vs. 152.9 +/- 9.6 cm; P < 0.05). Body mass index and fat percentage were not statistically different from control values. Densitometric values at final evaluation in groups A and B together were lower than in controls, but the differences were not statistically significant. The vBMD was significantly higher in group B than in group A at the end of treatment period (0.213 +/- 0.022 g/cm(3) vs. 0.192 +/- 0.021 g/cm(3); P < 0.01) and at final evaluation (0.246 +/- 0.023 g/cm(3) vs. 0.227 +/- 0.024 g/cm(3); P < 0.05). The percentage change (Delta%) between the start and end of treatment period in AP-BMD and vBMD was significantly higher in group B than in group A (Delta% AP-BMD: 20.36% +/- 1.10% vs. 16.16% +/- 1.90%, P < 0.01; Delta% vBMD: 19.08% +/- 3.52% vs. 9.26% +/- 5.15%; P < 0.01) and also between the start of treatment and final evaluation (Delta% AP-BMD: 61.23% +/- 1.61% vs. 56.97% +/- 1.45%, P < 0.01; Delta% vBMD: 36.69% +/- 5.01% vs. 28.01% +/- 5.76%, P < 0.01). In all our females with CPP treated with GnRHa, bone densitometric parameters were in the normal range for age and sex. However, bone mass achievement seemed to be better preserved in the group of patients supplemented with calcium.

Prevention of bone demineralization by calcium supplementation in precocious puberty during gonadotropin-releasing hormone agonist treatment.

We have previously demonstrated a negative impact on peak bone mass in girls with precocious puberty treated with GnRH agonist (GnRHa). Several studies have shown that a high calcium intake positively influences bone mass in prepubertal girls and leads to a higher peak bone mass. The aim of this study was to evaluate the effect of calcium supplementation in girls with precocious puberty during GnRHa treatment. Forty girls affected by true central precocious puberty and treated with the GnRHa triptorelin were studied for 2 yr. After diagnosis, the patients were randomly assigned to three groups: group A, treated only with GnRHa; group B, treated for 12 months solely with GnRHa and then supplemented with calcium gluconolactate/carbonate (1 g calcium/day in two doses) for 12 months; and group C, treated from the beginning with combined GnRHa and calcium. Bone mineral density (BMD) at the lumbar spine was measured by dual energy x-ray absorptiometry at the beginning of the study and after 12 and 24 months and was expressed as the calculated true volumetric density (BMDv) in milligrams per cm3. Group A showed a decrease in absolute BMDv levels, in SD score for chronological age (CA), and even more in SD score for bone age (BA). Group B showed the same behavior during the first year, but this trend was reversed in the second year, when calcium supplementation was added to GnRHa treatment. Group C showed an increase in absolute BMDv levels and in SD score for CA and BA. BMDv variations (expressed as absolute values, SD score for CA, and SD score for BA) became statistically significant at 24 months between groups C and A (P = 0.036, P = 0.032, and P = 0.025, respectively). The behavior of the lumbar spine BMDv in the three groups is consistent with a positive effect of calcium supplementation during GnRHa treatment. In calcium-supplemented patients, the normal process of bone mass accretion at puberty is preserved despite GnRHa treatment. Therefore, the reduction in BMD during GnRHa treatment in girls with precocious puberty is at least completely reversible and preventable if calcium supplementation is associated from the beginning.

Reduction of blood flow impedance in the uterine arteries of infertile women with electro-acupuncture.

In order to assess whether electro-acupuncture (EA) can reduce a high uterine artery blood flow impedance, 10 infertile but otherwise healthy women with a pulsatility index (PI) >=3.0 in the uterine arteries were treated with EA in a prospective, non-randomized study. Before inclusion in the study and throughout the entire study period, the women were down-regulated with a gonadotrophin-releasing hormone analogue (GnRHa) in order to exclude any fluctuating endogenous hormone effects on the PI. The baseline PI was measured when the serum oestradiol was <=0.1 nmol/l, and thereafter the women were given EA eight times, twice a week for 4 weeks. The PI was measured again closely after the eighth EA treatment, and once more 10-14 days after the EA period. Skin temperature on the forehead (STFH) and in the lumbrosacral area (STLS) was measured during the first, fifth and eighth EA treatments. Compared to the mean baseline PI, the mean PI was significantly reduced both shortly after the eighth EA treatment (P < 0.0001) and 10-14 days after the EA period (P < 0.0001). STFH increased significantly during the EA treatments. It is suggested that both of these effects are due to a central inhibition of the sympathetic activity.

Decreased bone density in elderly men treated with the gonadotropin-releasing hormone agonist decapeptyl (D-Trp6-GnRH).

Administration of GnRH agonist analogs to women may result in a hypoestrogenic state and bone mass reduction. In the present study we examined bone mineral density (BMD) and parameters of mineral metabolism in elderly men with benign prostatic hyperplasia before and during a hypoandrogenic state induced by the long-acting GnRH agonist D-Trp6-LHRH (decapeptyl). Our results showed that decapeptyl treatment caused a significant decrease in serum testosterone concentrations in all patients and resulted in a significant decrease in individual vertebral BMD in 10 of 17 patients. A significant decrease in BMD was observed in 5 patients after 6 months of treatment. Another 5 patients showed a decreased BMD only after 12 months. The mean serum concentrations of osteocalcin, phosphorus, and alkaline phosphatase activity increased after 6-12 months of treatment with decapeptyl. Serum calcium, vitamin D metabolites, and PTH concentrations remained unchanged during treatment. Urinary calcium excretion was slightly, but not significantly, increased after 6 months of treatment. These results demonstrate that long-acting GnRH agonist treatment may cause high turnover accelerated bone loss in some men during the first year of GnRH agonist treatment, as has been previously shown in women.
