A prospective, single-centre, single-arm, open label study of the long term use of a gonadotropin releasing hormone agonist (Triptorelin SR, 11.25?mg) in combination with Tibolone add-back therapy in the management of chronic cyclical pelvic pain.

ABSTRACT: BACKGROUND:Chronic cyclic pelvic pain (CCPP) affects women's quality of life and pituitary downregulation is often used for symptomatic relief. However, prolonged suppression of ovarian function is associated with menopausal side effects and can lead to osteoporosis. Currently, the use of gonadotropin releasing hormone agonists (GnRHa) for treatment of CCPP is usually restricted to 6-9?months, limiting their efficacy. There is limited information regarding safety and efficacy with longer-term use. The aim of this study is to examine the safety and efficacy of long-term (24?months) pituitary down-regulation with the GnRHa (Triptorelin SR) with add-back therapy (ABT) using Tibolone for symptom relief in women with CCPP. METHODS:A single-arm, prospective clinical trial at a Tertiary University Teaching Hospital of 27 patients receiving Triptorelin SR (11.25?mg) and Tibolone (2.5?mg). Outcomes measures were the safety of treatment assessed by clinical examination, haematological markers, liver and renal function tests and bone mineral density (BMD) at 12, 18 and 24?months as well as at 6?months post-treatment. Pain and health-related quality of life (HR-QoL) assessed using the endometriosis health profile (EHP-30) and chronic pain grade (CPG) questionnaires. RESULTS:There was no evidence for any significant harmful effects on any of the measured haematological, renal or liver function tests. Although results regarding the effect on BMD are not conclusive there is an increased risk of development of osteopaenia after 12?months of treatment. Pain and HRQoL assessments showed significant improvement during medication, but with deterioration after treatment cessation. CONCLUSION:Long- term Triptorelin plus Tibolone add-back therapy in women suffering from CCPP does not appear to be associated with significant serious adverse events apart from the possibility of deterioration in the BMD that needs to be monitored. This mode of therapy appears to be effective in pain relief and in improving quality of life over a 24-month period. TRIAL REGISTRATION:Clinical trials database NCT00735852.

Project description:To assess whether add-back therapy with norethindrone acetate or norethindrone acetate plus conjugated equine estrogens is superior to maintain bone health in adolescents and young women using gonadotropin-releasing hormone agonists for endometriosis. Gonadotropin-releasing hormone agonists are associated with deleterious effects on bone. Hormonal add-back may mitigate these effects.Adolescents and young women (n=51) received a random, double-blind assignment to add-back with norethindrone acetate (5 mg/day) plus conjugated equine estrogens (0.625 mg/day) or norethindrone acetate plus placebo for 12 months. Body composition, bone mineral content, and bone mineral density (BMD) were obtained by dual-energy X-ray absorptiometry every 6 months. Quality-of-life measures were collected every 3 months. Intention-to-treat comparison of outcomes was conducted by repeated-measures analysis of variance.Thirty-four adolescents and young women completed the trial; dropouts did not differ from those who completed the trial. Bone mineral density was normal at baseline. At 12 months, total body bone mineral content and BMD had increased in the norethindrone acetate plus conjugated equine estrogens group (bone mineral content +37 g, P<.001 and BMD +0.012 g/cm, P=.05), but not in those receiving norethindrone acetate plus placebo (bone mineral content P=.19 and BMD P=.95). Lean mass increased only in those receiving conjugated equine estrogens (+1.4 kg, P=.001). Improvements in physical functioning domains of quality-of-life assessments were greater with norethindrone acetate plus conjugated equine estrogens (P=.005). No differences were seen at the hip or lumbar spine by dual-energy X-ray absorptiometry. No significant adverse events occurred.Hormonal add-back successfully preserved bone health and improved quality of life for adolescents and young women with endometriosis during 12 months of gonadotropin-releasing hormone agonist therapy. Combination norethindrone acetate plus conjugated equine estrogens add-back appears to be more effective for increasing total body bone mineral content, areal BMD, and lean mass than norethindrone acetate monotherapy.ClinicalTrials.gov; www.clinicaltrials.gov, NCT00474851.I.

Project description:BACKGROUND:The main objective of the present work was to compare the effects of the gonadotropin-releasing hormone agonist (GnRH-a) and GnRH antagonist (GnRH-ant) on the gene expression profiles of oocytes obtained from Iranian infertile couples undergoing in vitro fertilization (IVF). METHODS:Fifty infertile couples who underwent IVF between June 2012 and November 2013 at the Infertility Center of Tehran Women General Hospital, Tehran University of Medical Sciences, were included in this study. We included women that had undergone IVF treatment because of male factor, tubal factor, or unexplained infertility. The women randomly underwent controlled ovarian stimulation (COS) with either the GnRH-a (n = 26) or the GnRH-ant (n = 24). We obtained 50 germinal vesicle (GV) oocytes donated by women in each group. After the sampling, pool of 50 GV oocytes for each group was separately analyzed by quantitative polymerase chain reaction (qPCR). RESULT:The expression levels of Adenosine triphosphatase 6 (ATPase 6), Bone morphogenetic protein 15 (BMP15), and Neuronal apoptosis inhibitory protein (NAIP) genes were significantly upregulated in the GnRH-ant group compared to the GnRH-a group, with the fold change of 3.990 (SD ± 1.325), 6.274 (SD ± 1.542), and 2.156 (SD ± 1.443), respectively, (P < 0.001). Growth differentiation factor 9 (GDF9) mRNA did not have any expression in the GnRH-a group; however, GDF9 mRNA was expressed in the GnRH-ant group. Finally, it was found that the genes involved in the DNA repairing and cell cycle checkpoint did not have any expression in either group. CONCLUSION:The present study showed, for the first time, the expression levels of genes involved in the cytoplasmic maturity (BMP15, GDF9), adenosine triphosphate production (ATPase 6), and antiapoptotic process (NAIP), in human GV oocytes were significantly higher in the GnRH-anta group than in the GnRH-a group in COS. Higher expression level of these genes when GnRH-ant protocol is applied, this protocol seems to be a more appropriate choice for women with poly cystic ovarian syndrome, because it can probably improve the expression of the aforementioned genes.
