OBJECTIVE GNRH analog (GNRHa) therapy has not been supported by beneficial effects on adult stature in girls with early puberty. Furthermore, an increased prevalence of polycystic ovary syndrome (PCOS) has been described in girls treated for central precocious puberty. Women with PCOS are at increased risk of cardiometabolic dysfunctions and infertility. Our aim was to assess GNRHa effectivenes...
In 2007, a hydrogel histrelin implant was approved for the treatment of children with central precocious puberty (CPP). Children with CPP commonly have reduced height potential due to premature closure of the epiphyseal growth plates from exposure to sex steroids. Gonadotropin-releasing hormone analog (GnRHa) treatment halts puberty and allows for improvement of adult height. A hydrogel implant...
BACKGROUND Gonadotropin-releasing hormone agonist (GnRHa)-stimulated luteinizing hormone (LH) is the standard hormonal assessment for both diagnosis and therapeutic monitoring of children with central precocious puberty (CPP). Use of unstimulated (random) LH levels may be helpful in diagnosis and has gained popularity in monitoring GnRHa therapy despite lack of validation against stimulated val...
PURPOSE The effects of gonadotropin-releasing hormone agonist (GnRHa) treatment on the energy metabolism in girls with central precocious puberty (CPP) are controversial. We focused the changes and related factors of serum levels of leptin and adiponectin in girls with CPP before and during GnRHa treatment. METHODS Thirty girls with idiopathic CPP were enrolled in the study. Their auxological...
OBJECTIVE To evaluate the effects of a gonadotropin releasing hormone agonist (GnRHa) injection prior to embryo transfer on implantation and pregnancy rate. MATERIALS AND METHODS We performed a retrospective analysis of patients undergoing in vitro fertilization (IVF) therapy with and without GnRHa preinstallation into the uterine cavity just before embryo transfer between January 2012 and Ma...
Clinical and laboratory diagnosis and treatment of central precocious puberty (CPP) remain challenging due to lack of standardization. The aim of this revision was to address the diagnostic and therapeutic features of CPP in Brazil based on relevant international literature and availability of the existing therapies in the country. The diagnosis of CPP is based mainly on clinical and biochemica...
In order to determine the changes in the expression of LH beta messenger ribonucleic acid (mRNA) during GnRH agonist (GnRHa) treatment (0.94 mg/28 days), the concentration of the mRNA of LH beta was assessed together with the serum LH concentration, pituitary LH content and LH response to GnRH at various times during long-acting GnRHa treatment in immature female rats. The serum LH concentratio...
In the setting of central precocious puberty (CPP), the motivation for hormonal intervention is to help the child to reach a taller adult stature than she would achieve otherwise. While gonadotropin-releasing hormone analogs (GnRHa) constitute an established treatment for improving adult stature in girls presenting with CPP up to age 6 (true precocious puberty), it is not yet clear whether or n...
Gene microarray was used to characterize the molecular environment of leiomyoma and matched myometrium during growth and in response to GnRH analog (GnRHa) therapy as well as GnRHa direct action on primary cultures of leiomyoma and myometrial smooth muscle cells (LSMC and MSMC). Unsupervised and supervised analysis of gene expression values and statistical analysis in R programming with a false...
BACKGROUND Recently, it has been demonstrated that, in patients down-regulated by GnRH analogues (GnRHa), a short-term pre-treatment with recombinant LH (rLH), prior to recombinant FSH (rFSH) administration, increases the number of small antral follicle prior to FSH stimulation and the yield of normally fertilized embryos. However, no data exist in the literature regarding the potential benefic...
