Abstract
Central precocious puberty (CPP) among males is less frequent than among females but more likely to have an underlying pathologic cause. Diagnosis of CPP is often straightforward among males because increased testicular volume, the first sign of puberty, can be verified although careful central nervous system (CNS) assessment is generally necessary. Treatment with gonadotropin-releasing hormone agonist (GnRHa) is indicated, given in conjunction with any therapy needed for CNS lesions. Monitoring of treatment usually can consist of evaluating growth and physical puberty and with testosterone levels as the only lab data. Short-term and long-term outcome data indicate efficacy and safety, although data are limited. Such data need to be reported.

Abstract
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.

Abstract
BACKGROUND Gonadotropin-releasing hormone analog (GnRHa) is the standard treatment for children with central precocious puberty (CPP). We assessed efficacy and safety of GnRHa treatment in girls with CPP and early fast puberty (EFP). METHODS This retrospective observational study included anthropometric, clinical and laboratory data retrieved from medical files of girls with CPP or EFP, treated with GnRHa and followed at a tertiary endocrine clinic during 2007-2021. RESULTS For both CPP (n = 144) and EFP (n = 231) groups, mean height-SDS at GnRHa initiation and termination and at the last follow-up visit was greater than mid-parental height-SDS (P < 0.001). Only among girls with EFP, mean BMI-SDS was higher at treatment termination than initiation (P = 0.025). Median ages at menarche of the CPP and EFP groups were 11.8 and 12.0 years. Menstrual irregularities were reported in 20.3% of girls with CPP and in 18.7% of those with EFP. Adverse effects to treatment were reported in 3.5% and 3.9% of girls with CPP and EFP, respectively. CONCLUSIONS In this large cohort, GnRHa treatment in girls with EFP was effective without significant adverse effects as in those with CPP. A randomized controlled trial is required to examine the psychological impact of GnRHa treatment of variant early puberty. IMPACT STATEMENT Gonadotropin-releasing hormone analog (GnRHa) is the standard treatment for central precocious puberty (CPP). We assessed efficacy and safety of GnRHa treatment in girls with early fast puberty (EFP), characterized by pubertal signs between ages 8-9 years with fast pubertal signs advancement and accelerated growth and bone maturation and in girls with CPP. We found in this large cohort that GnRHa treatment in girls with EFP was effective and safe as in those with CPP. A prospective randomized controlled trial is required to examine the psychological impact of GnRHa treatment of variant early puberty.

Abstract
CONTEXT Children with congenital adrenal hyperplasia (CAH) are at risk for early puberty. Gonadotropin-releasing hormone analog (GnRHa) is frequently used and can decrease bone mineral density (BMD). OBJECTIVE Our aim was to investigate the effect of GnRHa therapy on BMD in a longitudinal study of patients with CAH spanning both childhood and adulthood. DESIGN AND SETTING Sixty-one patients with classic CAH due to 21-hydroxylase deficiency (20 treated with GnRHa) were followed with dual-energy X-ray absorptiometry (DXA) scans at puberty onset, attainment of adult height, and during early adulthood. MAIN OUTCOME MEASURES Whole body, lumbar spine, femoral neck, total hip, and distal radius BMD z-score at adult height. Longitudinal BMD and adult height were also assessed. RESULTS Twenty patients received GnRHa for an average of 4.5 ± 2 years. There were no differences in BMD between GnRHa-treated and -untreated groups at adult height for all sites. Overall, the follow-up DXA during early adulthood showed decreases in BMD z-scores for whole body (P = .01), lumbar spine (P < .0001), femoral neck (P = .06), total hip (P = .009), and distal radius (P = .05). GnRHa treatment correlated with improved height outcomes compared to predicted height at puberty onset after adjusting for midparental height (P = .02). Patients in both groups achieved similar adult height. CONCLUSION In children with CAH, GnRHa does not compromise BMD. However, BMD decreases with time and during the second and third decades of life is a possible effect of chronic supraphysiologic glucocorticoids. Children with CAH who experience early puberty benefit from GnRHa treatment as evidenced by the positive effect on height.

Abstract
The Committee of Central Precocious Puberty of Korean Pediatrics and Adolescents of the Korean Society of Pediatric Endocrinology has newly developed evidence-based 2022 clinical practice guidelines for central precocious puberty in Korean children and adolescents. These guidelines provide the grade of recommendations, which includes both the strength of recommendations and the level of evidence. In the absence of sufficient evidence, recommendations are based on expert opinion. These guidelines have been revised and supplement the previous guidelines "Clinical Guidelines for Precocious Puberty 2011," and are drawn from a comprehensive review of the latest domestic and international research and the grade of recommendation appropriate to the domestic situation. This review summarizes the newly revised guidelines into 8 key questions and 27 recommendations and consists of 4 sections: screening, diagnosis, treatment, and long-term outcome of central precocious puberty.

International Consensus Guideline on Small for Gestational Age (SGA): Etiology and Management from Infancy to Early Adulthood. Endocr Rev 2023; 44:539-565. [PMID: 36635911 PMCID: PMC10166266 DOI: 10.1210/endrev/bnad002] [Citation(s) in RCA: 24] [Impact Index Per Article: 24.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 10/31/2022] [Accepted: 01/10/2023] [Indexed: 01/14/2023]
Abstract
This International Consensus Guideline was developed by experts in the field of SGA of 10 pediatric endocrine societies worldwide. A consensus meeting was held and 1300 articles formed the basis for discussions. All experts voted about the strengths of the recommendations. The guideline gives new and clinically relevant insights into the etiology of short stature after SGA birth, including novel knowledge about (epi)genetic causes. Besides, it presents long-term consequences of SGA birth and new treatment options, including treatment with gonadotropin-releasing hormone agonist (GnRHa) in addition to growth hormone (GH) treatment, and the metabolic and cardiovascular health of young adults born SGA after cessation of childhood-GH-treatment in comparison with appropriate control groups. To diagnose SGA, accurate anthropometry and use of national growth charts are recommended. Follow-up in early life is warranted and neurodevelopment evaluation in those at risk. Excessive postnatal weight gain should be avoided, as this is associated with an unfavorable cardio-metabolic health profile in adulthood. Children born SGA with persistent short stature < -2.5 SDS at age 2 years or < -2 SDS at age of 3-4 years, should be referred for diagnostic work-up. In case of dysmorphic features, major malformations, microcephaly, developmental delay, intellectual disability and/or signs of skeletal dysplasia, genetic testing should be considered. Treatment with 0.033-0.067 mg GH/kg/day is recommended in case of persistent short stature at age of 3-4 years. Adding GnRHa treatment could be considered when short adult height is expected at pubertal onset. All young adults born SGA require counseling to adopt a healthy lifestyle.

Efficacy and safety of a 4-year combination therapy of growth hormone and gonadotropin-releasing hormone analogue in pubertal girls with short predicted adult height.

Abstract
OBJECTIVES To improve adult height in pubertal girls with a poor height prediction, treatment with growth hormone (GH) can be used in combination with a gonadotropin releasing hormone agonist (GnRHa), to delay closure of the growth plates. However, there are few studies to support this practice, and they show conflicting results. The objective of this trial is to assess the safety and efficacy of this combination treatment in early pubertal girls with a short predicted height, in comparison with matched controls. DESIGN PATIENTS AND METHODS We designed an open-label, multicenter, interventional case-control study. Early pubertal girls with predicted adult height (PAH) below -2.5 SDS, were recruited in tertiary care centers in Belgium. They were treated for four years with GH and GnRHa. The girls were followed until adult height (AH) was reached. AH vs PAH, AH vs Height at start, and AH vs Target Height (TH) were evaluated, as well as safety parameters. Control data were assembled from historical patient files or from patients who preferred not to participate in the study. RESULTS Sixteen girls with mean age ( ± SD) at start of 11.0 years (± 1.3) completed the study protocol and follow-up. Their mean height ( ± SD) increased from 131.3 ± 4.1 cm (-2.3 ± 0.7 SDS) at start of treatment to 159.8 ± 4.7 cm (-1.1 ± 0.7 SDS) at AH. In matched controls, height increased from 132.3 ± 4.2 cm (-2.4 ± 0.5 SDS) to 153.2 ± 3.4 cm (-2.1 ± 0.6 SDS) (p<0.001). AH surpassed initial PAH by 12.0 ± 2.6 cm in treated girls; and by 4.2 ± 3.6 cm in the controls (p<0.001). Most treated girls reached normal adult height (>-2SD) (87.5%) and 68.7% reached or superseded the target height (TH), which was the case in only a minority of the controls (37.5% and 6.2%, respectively) (p= 0.003 and 0.001). A serious adverse event possibly related to the treatment, was a fracture of the metatarsals. CONCLUSION A four-year GH/GnRHa treatment in early pubertal girls with a poor PAH seems safe and results in a clinically relevant and statistically significant increase in AH compared with matched historical controls.

Abstract
PURPOSE OF REVIEW In this review, we have summarized the current data on the effect of sexual precocity and treatment with gonadotropin-releasing hormone analogues (GnRHa) on body composition. RECENT FINDINGS Higher body weight and weight gain in infancy and childhood may increase the risk of early puberty in girls. The relation between BMI and pubertal onset in boys is controversial. Current studies draw attention to the fact that a similar relationship may exist in boys too. Obesity prevalence is high among girls with central precocious puberty (CPP) and treatment with GnRHa has a different effect on BMI according to baseline body composition. Although BMI values of normal weight girls tend to increase under treatment, they return to normal following treatment. The few studies that have followed up body composition longitudinally in girls show a gradual increase in adiposity, decrease in muscle mass and bone mineral density during GnRHa treatment, whereas bone mass was preserved after treatment. Adequate data are not available in boys to determine the effect of GnRHa therapy on body composition. SUMMARY Body composition and fat distribution should be monitored longitudinally in patients with CPP treated with GnRHa to ascertain the long-term effects of therapy.

Abstract
Gonadotropin-releasing hormone agonist (GnRHa) therapy is used to control puberty progression and it preserves height potential in patients with idiopathic central precocious puberty (ICPP). This study evaluated the correlation between weight and height gain at menarche following GnRHa treatment among girls with ICPP and relatively central early puberty (EP). We investigated height/weight trends and changes in height from diagnosis to menarche in girls with ICPP and EP treated with GnRHa. The mean difference in height (Δheight) from treatment cessation to menarche was 9.79 ± 3.53 cm. Girls were divided into girls with Δheight ≥ 9.79 cm (Group 1) and girls with Δheight < 9.79 cm (Group 2). Although near adult height was significantly higher in Group 1, the mean body mass index (BMI) and weight were significantly lower at diagnosis, treatment discontinuation, and menarche. The BMI and weight at the three time points were negatively correlated with height. Girls with higher BMI at all three time points had slower growth rates during the study period. Considering that BMI and body weight were closely related to Δheight, proper management of BMI and body weight of girls receiving early puberty treatment might contribute to growth during and after GnRHa treatment.

Abstract
Gonadotropin-releasing hormone agonists (GnRHa's) are the standard treatment for children with central precocious puberty (CPP). We aim to present data on available GnRHa options with an easy-to-review table and discuss factors that influence treatment selection. Five GnRHa's are currently FDA-approved and prescribed in the US and published data suggest similar safety and efficacy profiles over the first year of treatment. One- and 3-month intramuscular (IM) leuprolide acetate (LA) have long-term safety and efficacy data and allow for flexible dosing. Six-month IM triptorelin pamoate offers a longer duration of treatment, but without long-term efficacy and outcome data. Six-month subcutaneous (SQ) LA combines a SQ route of injection and long duration of action but lacks long-term efficacy and outcome data. The 12-month SQ histrelin acetate implant avoids injections and offers the longest duration of action, but requires a minor surgical procedure with local or general anesthesia. Factors in treatment selection include route of administration, needle size, injection volume, duration of action, and cost. The current GnRHa landscape provides options with varying benefits and risks, allowing physicians and caregivers to select the most appropriate therapy based on the specific needs and concerns of the child and the caregiver. Agents have different advantages and disadvantages for use, with no one agent displaying superiority.

Abstract
With the declining age at onset of puberty and increasing prevalence of childhood obesity, early breast development in young obese girls has become a more frequent occurrence. Here, we examine available literature to answer a series of questions regarding how obesity impacts the evaluation and management of precocious puberty. We focus on girls as the literature is more robust, but include boys where literature permits. Suggestions include: (1) Age cutoffs for evaluation of precocious puberty should not differ substantially from those used for nonobese children. Obese girls with confirmed thelarche should be evaluated for gonadotropin-dependent, central precocious puberty (CPP) to determine if further investigation or treatment is warranted. (2) Basal luteinizing hormone (LH) levels remain a recommended first-line test. However, if stimulation testing is utilized, there is a theoretical possibility that the lower peak LH responses seen in obesity could lead to a false negative result. (3) Advanced bone age (BA) is common among obese girls even without early puberty; hence its diagnostic utility is limited. (4) Obesity does not eliminate the need for magnetic resonance imaging in girls with true CPP. Age and clinical features should determine who warrants neuroimaging. (5) BA can be used to predict adult height in obese girls with CPP to inform counseling around treatment. (6) Use of gonadotropin-releasing hormone analogues (GnRHa) leads to increased adult height in obese girls. (7) Obesity should not limit GnRHa use as these agents do not worsen weight status in obese girls with CPP.

Abstract
Hyperthecosis is defined as the presence of nests of luteinized theca cells in the ovarian stroma. Persistent testosterone released by ovarian theca cells is unmasked postmenopausally through the loss of granulosa cell-mediated aromatization of testosterone to estradiol. Ovarian hyperthecosis (OH) usually presents with symptoms of hyperandrogenism and is often described as a severe or extreme form of Polycystic Ovary Syndrome (PCOS). Serum testosterone levels in excess of 150 ng/dl (>5.2 nmol/l) are seen in affected patients and this threshold is used to confirm a diagnosis. Treatment of hyperthecosis is multi-faceted. It addresses the attendant hyperandrogenism (hirsutism and virilization) as well as metabolic complications such as obesity and insulin resistance. Ultimately, laparoscopic bilateral salpingo-oophorectomy is definitive treatment. This remains the treatment of choice in postmenopausal women whereas treatment using GnRH agonists may be used in women of reproductive age, especially younger women. Nevertheless, if serum testosterone remains elevated despite several months of therapy with a GnRH agonist, surgery is often required for biopsy sample collection and further definitive therapy. In order to mitigate the common clinical manifestations of hyperandrogenism, anti-androgen therapy (either cyproterone acetate or spironolactone) may be used to suppress the actions of testosterone on tissues. In patients with impaired glucose metabolism and insulin resistance, Metformin should also be considered as part of treatment. Combined, such a treatment regimen will often lead to decreased ovarian androgen secretion.

Abstract
The present study was designed to examine the effects of suppressing pubertal onset with leuprolide acetate, a gonadotropin releasing hormone (GnRH) agonist. Starting on postnatal day (PD) 25, male Long-Evans rats were injected daily with either leuprolide acetate (25 μg/kg dissolved in 0.9% sterile physiological saline; n = 13) or sterile physiological saline (1.0 ml/kg 0.9% NaCl; n = 14) for a total of 25 days. Males were monitored daily for signs of puberty (i.e., preputial separation). On the last day of leuprolide treatment (PD 50), half of each treatment group was injected with 10.0 μg of estradiol benzoate (EB) daily for three consecutive days (PD 50-52) and 1.0 mg of progesterone (P) on the 4th day (PD 53), whereas the other half of each treatment group received oil injections. Four hours after P injections, all subjects were given the opportunity to interact with a gonadally-intact male and a sexually receptive female rat (i.e., a partner-preference test with and without physical contact). Copulatory behavior and sexual motivation were measured. Hormone injections and mating tests were repeated weekly for a total of 3 consecutive weeks. Results showed that leuprolide delayed puberty as well as the development of copulatory behavior and the expression of sexual motivation. By the last test, the leuprolide-treated subjects showed signs of catching up, however, many continued to be delayed. Estradiol and progesterone mildly feminized male physiology (e.g., decreased testes weight and serum testosterone) and behavior (e.g., increased lordosis), but did not interact with leuprolide treatment.

Abstract
OBJECTIVES To determine appetite-regulating hormone levels in girls with central precocious puberty (CPP) before and after 20 weeks of gonadotropin-releasing hormone analogue (GnRH-A) treatment. METHODS Eighteen newly diagnosed CPP girls were enrolled. Body composition measured by bioelectrical impedance analysis and GnRH-A test were performed with fasting serum leptin, ghrelin and peptide YY (PYY) measurements at baseline (before) and after 20 weeks of GnRH-A treatment. RESULTS Following GnRH-A treatment, all patients had prepubertal gonadotropin and estradiol levels. Mean (SD) fat mass index (FMI) was significantly increased from 4.5 (1.7) to 5.0 (1.8) kg/m2 after treatment. Also, median (IQR) serum leptin level was significantly increased from 6.9 (4.2-8.6) to 7.4 (5.3-13.1) ng/mL. FMI had a positive correlation with serum leptin level (r=0.64, p=0.004). In contrast, no significant changes of serum ghrelin and PYY levels were observed. CONCLUSIONS Decreased estrogen following short-term GnRH-A treatment in CPP girls may cause an increase in appetite and consequently an elevation of FMI. Increased serum leptin may be a result of having increased FMI secondary to an increase in appetite.

Abstract
BACKGROUND The impact of gonadotropin-releasing-hormone-analogue (GnRHa) treatment on weight and body composition is controversial. Exploring the nutritional, psychological patterns of this population may aid to clarify this propensity to gain weight. This prospective observational study aimed to evaluate longitudinal changes in adiposity, nutrition and quality of life in girls with central precocious/early-fast puberty (CPP/EFP) during GnRHa treatment. METHODS Thirty-two GnRHa-treated girls with CPP/EFP and 27 prepubertal girls (7-10 years) were included in the analysis. Outcome measures assessed at baseline for CPP/EFP and the control groups and during up to two years of GnRHa treatment for the CPP/EFP group, included anthropometrics, body-composition, basal-metabolic-rate (BMR), 3-day food-diaries, child eating-behavior questionnaire, and pediatric quality-of-life questionnaire (PedsQL). RESULTS Girls with CPP/EFP had higher pretreatment BMI-SDS, fat percentages, waist circumference and waist-per-height (p<0.01 for all), and lower psychosocial functioning than controls (p<0.05). Changes in anthropometric and body composition measurements indicated a gradual increase in adiposity and a decrease in muscle mass (p<0.001 for all). Dynamics in body composition could not be explained by the participants' self-reported dietary patterns and physical activity levels or by the measured BMR, which revealed an adequate and relatively low energy intake as compared to energy requirements. A gradual decline in physical functioning (PedsQL) after one and two years of GnRHa treatment was observed (p<0.001). CONCLUSIONS Our findings highlight the need for comprehensive surveillance in girls with CPP/EFP. Dynamics in weight status and body composition during GnRHa treatment indicate the need for tailored nutritional and physical activity counseling aimed at preventing obesity.

Abstract
Puberty, which in humans is considered to include both gonadarche and adrenarche, is the period of becoming capable of reproducing sexually and is recognized by maturation of the gonads and development of secondary sex characteristics. Gonadarche referring to growth and maturation of the gonads is fundamental to puberty since it encompasses increased gonadal steroid secretion and initiation of gametogenesis resulting from enhanced pituitary gonadotropin secretion, triggered in turn by robust pulsatile GnRH release from the hypothalamus. This chapter reviews the development of GnRH pulsatility from before birth until the onset of puberty. In humans, GnRH pulse generation is restrained during childhood and juvenile development. This prepubertal hiatus in hypothalamic activity is considered to result from a neurobiological brake imposed upon the GnRH pulse generator resident in the infundibular nucleus. Reactivation of the GnRH pulse generator initiates pubertal development. Current understanding of the genetics and physiology of the brake will be discussed, as will hypotheses proposed to account for timing the resurgence in pulsatile GnRH and initiation of puberty. The chapter ends with a discussion of disorders associated with precocious or delayed puberty with a focus on those with etiologies attributed to aberrant GnRH neuron anatomy or function. A pediatric approach to patients with pubertal disorders is provided and contemporary treatments for both precocious and delayed puberty outlined.

Abstract
BACKGROUND In children born small for gestational age (SGA) with persistent short stature, 2 years of gonadotropin-releasing hormone analogue (GnRHa), in addition to long-term growth hormone (GH) treatment, can improve adult height. We assessed safety on metabolic and bone health of GnRHa/GH treatment during 5 years after cessation of GH. METHODS A total of 363 young adults born SGA, previously treated with combined GnRHa/GH or GH-only, were followed for 5 years after attainment of adult height at GH cessation and 2 and 5 years thereafter. Data at 5 years after GH cessation, at age 21 years, were also compared with 145 age-matched adults born appropriate for gestational age (AGA). Frequently sampled intravenous glucose tolerance (FSIGT) tests were used to assess insulin sensitivity, acute insulin response, and β-cell function. Body composition and bone mineral density (BMD) was determined by dual-energy x-ray absorptiometry (DXA) scans. FINDINGS In the GnRHa/GH and GH-only groups, fat mass increased during the 5 years after GH cessation, but the changes in FSIGT results, body composition, blood pressure, serum lipid levels, and BMD were similar in both groups. At age 21 years, the GnRHa/GH group had similar fat mass, FSIGT results, blood pressure, serum lipid levels and BMD-total body as the GH-only group and the AGA control group, a higher BMD-lumbar spine and lower lean body mass than the AGA control group. INTERPRETATION This study during 5 years after GH cessation shows that addition of 2 years of GnRHa treatment to long-term GH treatment of children short in stature born SGA has no unfavorable effects on metabolic and bone health in early adulthood.

Abstract
This update, written by authors designated by multiple pediatric endocrinology societies (see List of Participating Societies) from around the globe, concisely addresses topics related to changes in GnRHa usage in children and adolescents over the last decade. Topics related to the use of GnRHa in precocious puberty include diagnostic criteria, globally available formulations, considerations of benefit of treatment, monitoring of therapy, adverse events, and long-term outcome data. Additional sections review use in transgender individuals and other pediatric endocrine related conditions. Although there have been many significant changes in GnRHa usage, there is a definite paucity of evidence-based publications to support them. Therefore, this paper is explicitly not intended to evaluate what is recommended in terms of the best use of GnRHa, based on evidence and expert opinion, but rather to describe how these drugs are used, irrespective of any qualitative evaluation. Thus, this paper should be considered a narrative review on GnRHa utilization in precocious puberty and other clinical situations. These changes are reviewed not only to point out deficiencies in the literature but also to stimulate future studies and publications in this area.

Abstract
Introduction Studies evaluating effects of gonadotropin-releasing hormone agonist (GnRHa) on weight and body-mass-index (BMI) in girls with idiopathic central precocious puberty (iCPP) include short-term effects. The aim of this study is to investigate changes in BMI during and 2 years after completion of GnRHa to determine the factors that may impact BMI in girls with iCPP. Methods Medical files of 138 girls who completed GnRHa were evaluated. All patients had weight and height measurements at the beginning and end of treatment, and 111 patients had anthropometric measurements 2 years after the completion of treatment. Results In the beginning, 82 (59.4%) had normal weight (NW), 42 (30.4%) were overweight (OW), and 14 (10.2%) were obese (OB). Analysis of BMI-standard deviation score (SDS) in the whole group showed an overall increase during GnRHa treatment (0.92 ± 0.74 vs. 1.20 ± 0.51, p < 0.001). Changes in BMI-SDS (ΔBMI-SDS) during GnRHa differed between NW and OW/OB (0.45 ± 0.31 vs. 0.03 ± 0.20, p < 0.001). BMI-SDSs of both groups returned to baseline scores (or initial levels) 2 years after the completion of treatment. Two factors affecting ΔBMI-SDS in multiple linear regression analyses were baseline BMI and Δheight-SDS, both correlated negatively with ΔBMI-SDS. Conclusions The present study is one of the studies evaluating BMI change over a long period of time in girls with CPP. Although BMI-SDS increased during GnRHa in NW girls, it was reversible in follow-up after treatment. However, BMI-SDS did not change during and in follow-up in OW/OB girls. Conserving BMI-SDS in OW/OB girls may be related to the fact that weight management programs were recommended for these patients. Dietary recommendations should be provided for children with NW who undergo GnRHa, as is the case for OW patients.

Abstract
Background The use of gonadotropin-releasing hormone agonists (GnRHa) for pubertal suppression has been associated with increased body mass index (BMI) in female subjects with central precocious puberty (CPP), although results have been so far conflicting. This study examined the effects of GnRHa therapy in both genders and in subjects treated for CPP, early puberty or short stature. Methods This was a longitudinal retrospective study of subjects followed at outpatient pediatric endocrinology clinics of an academic medical center from 2005 to 2014 receiving GnRHa therapy. Results At 12 months, subjects on depot GnRHa had a statistically significant increase in BMI standard deviation score (SDS) from baseline (0.13 ± 0.35, p < 0.02). Subjects with short stature (0.17 ± 0.34, p < 0.02) but not early or precocious puberty, and subjects with normal baseline BMI (0.18 ± 0.38, p < 0.02) had significant increases in BMI SDS; no significance was noted at 24 months. Male subjects did not have a significant increase in BMI SDS, whereas female subjects did (0.11 ± 0.36, p < 0.01). Conclusions Subjects with short stature, normal BMI at baseline and female sex had significant increases in BMI SDS at 12 months. This is the first study to show an increase in BMI SDS in children treated with GnRHa for short stature, and is one of the few studies to assess BMI changes in males.

Abstract
Central precocious puberty (CPP) is defined as an early pubertal development that occurs before the age of 9 years in boys and 8 years in girls. It results from premature activation of the hypothalamic-pituitary-gonadal axis. Gonadotropin-releasing hormone agonists (GnRHa) have been the gold standard therapy for CPP for more than 30 years. These compounds have a high affinity for the pituitary LHRH receptor and are resistant to enzymatic degradation. Through continuous stimulation, GnRHa inhibit the pulsatile secretion of gonadotropin, resulting in hormonal suppression, cessation of pubertal development, and normalization of growth and skeletal maturation rates. The goal of therapy is to halt pubertal progression and delay epiphyseal maturation that leads to improvement of final adult height. There are no widely accepted guidelines for how long to continue treatment with a GnRHa for CPP, and individual practice varies widely. Furthermore, conflicting results have been published on the long-term effects of GnRHa therapy in patients with CPP. Therefore, we reviewed the current literature focusing our attention on the long-term effects and the significant adverse drug reactions (ADRs) observed during treatment with GnRHa in patients with CPP. Our review may provide the necessary data to enable clinicians to administer GnRHa in the safest and most appropriate way. Further studies are necessary to identify the mechanisms of development of potential adverse drug reactions related to GnRHa therapy in CPP.

Abstract
Background Puberty is associated with a physiological decline in insulin sensitivity (IS). Overweight (OW) and obesity (OB) are common among girls with central precocious puberty (CPP). CPP is considered a risk factor for metabolic diseases. The aim of this study was to assess surrogate measures of IS, body mass index (BMI) and other metabolic parameters in CPP girls at diagnosis and during treatment with gonadotropin-releasing hormone analogues (GnRHa). Methods We present a prospective longitudinal study of CPP girls. The standard oral glucose tolerance test, homeostatic model assessment of insulin resistance (HOMA-IR), whole-body IS index (ISI) and fasting lipid profiles were evaluated at diagnosis, and at 6 and 12 months of treatment. Results Nineteen CPP girls were included; 17 were evaluable. At baseline, seven patients had normal weight (NW), five were OW and five were OB. During GnRHa treatment no significant changes were observed in BMI, HOMA-IR or ISI when considering the whole group. Whereas, when we analyzed patients according to BMI status, in NW patients, BMI increased significantly with no changes in HOMA-IR or ISI along treatment. In the OW/OB group, no significant differences were observed in BMI, HOMA-IR or ISI. Conclusions Girls with CPP showed a high frequency of OW/OB and a high prevalence of IR. GnRHa did not affect BMI, IS or the lipid profile when considering the whole cohort of patients. However, there was an increase in BMI in NW girls but not in OW/OB patients.

Abstract
Puberty suppression is the reversible first step of endocrine medical treatment in transgender youth, and allows for two very important aspects of transgender management. Firstly, it buys the patient, family and their medical team time to fully evaluate the presence and persistence of gender dysphoria. Secondly, it successfully prevents the development of cis-gender unwanted secondary sexual characteristics. The latter, when present, almost certainly increase the burden of psychological co-morbidity for any transgender person. This management is modelled from treatment of gonadotropin-dependent precious puberty, with use of GnRH agonists at its core. With the increasing number of transgender youth treated, and the changing demographics of patients seeking medical care, providers are faced with the decision to start puberty blockade at younger ages than previous decades. This article will review the rationale behind puberty blockade for transgender children, the providers' options for achieving this goal, the emerging literature for potential adverse effects on such an approach, as well as identify directions of potential future research.

Abstract
PURPOSE Reported changes in body mass index (BMI) in central precocious puberty (CPP) during and after gonadotropin-releasing hormone analog (GnRHa) treatment are inconsistent. We, therefore, investigated auxological parameters in GnRHa-treated girls with idiopathic CPP (ICPP) until attainment of near final height (NFH). METHODS From the medical records of 59 ICPP girls who attained NFH after GnRHa therapy, auxological changes were compared between overweight (BMI≥85th percentile) and normal-weight (BMI<85th percentile) groups. BMIs were changed into standard deviation scores (BMISDSs) for subject chronologic age (BMISDS-CA) and bone age (BMISDS-BA). RESULTS The incidence of overweight including obesity was high at the start of therapy (35.6%). The predicted adult height (PAH) at start of therapy was significantly shorter than the midparental height (MPH), whereas PAH at end of therapy approached MPH, and NFH was greater than MPH. Height velocity (HV) in the overweight group was higher during GnRHa therapy than that in the normal-weight group, but those in the two groups were not different after therapy until NFH. Both BMISDS-CA and BMISDS-BA increased significantly during therapy, but both BMISDSs decreased significantly after therapy until NFH. At NFH, neither BMISDS was different from that at baseline. In the normal-weight group, both BMISDSs increased during therapy and were maintained until NFH. In the overweight group, neither BMISDS changed during therapy, but there was a decrease after therapy until NFH. CONCLUSIONS The different patterns of BMISDS change during and after GnRHa therapy until NFH between the 2 groups were related to the different HV during GnRHa therapy.

Abstract
BACKGROUND Parental anxiety about the impact of puberty/menses, particularly in girls with severe disability leads to seeking therapeutic pubertal suppression. We aim to explore maternal attitudes and reasons for seeking pubertal suppression. METHODS Mothers of girls receiving gonadotropin -releasing hormone analogue therapy in Mafraq hospital, Abu Dhabi were enrolled in the study. A semistructured interview was conducted to ascertain possible reasons for delaying puberty. The study group was divided into girls with a disability with central precocious puberty (CPP) or normal puberty and girls without a disability presenting with CPP. RESULTS 42 mother-daughter pairs were enrolled and divided into two groups; group A: 15 girls with CPP with no disability; group B: 27 girls with disability (10 had CPP (group B1) and 17 had normal pubertal timing (group B2)). Mothers in group A aimed to delay puberty, while in group B, 13 (48%) mothers desired to halt puberty and 7 (26%) requested permanent surgical intervention. Fear of short stature (15, 100%), inability to cope psychologically (10, 67%) and fear of peer rejection (9, 60%) were the main concerns in group A. In group B, mothers were concerned about menstrual hygiene management (25, 92.5%), fear of child abuse or unwanted pregnancy (15, 55%) and fear of inability to express pain/discomfort with menstruation (8, 30%). CONCLUSION Mothers of girls with a disability commonly seek medical help to delay/halt puberty due to concerns about menstrual hygiene. Short final height was the main concern for girls without a disability. Culture and religion play an important role in puberty management in girls with a disability.

Abstract
Purpose The potential effect of gonadotropin-releasing hormone agonist (GnRHa) treatment on the weight of girls with central precocious puberty (CPP) remains a controversy. We investigated anthropometric changes during and after GnRHa treatment among girls with CPP. Methods This retrospective study evaluated data from 127 girls with CPP who received GnRHa treatment for ≥2 years. Height, weight, and body mass index (BMI) values were compared at the baseline (visit 1), after 1 year of GnRHa treatment (visit 2), the end of GnRHa treatment (visit 3), and 6–12 months after GnRHa discontinuation (visit 4). Results The height z score for chronological age (CA) increased continuously between visit 1 and visit 4. No significant differences were observed in BMI z score for CA between visits 1 and 4. However, an increasing trend in the BMI z score for bone age (BA) was observed between visits 1 and 4. The numbers of participants who were of normal weight, overweight, and obese were 97, 22, and 8, respectively, at visit 1, compared to 100, 16, and 11, respectively, at visit 4 (P=0.48). Conclusion Among girls with CPP, the overall BMI z score for CA did not change significantly during or after GnRHa treatment discontinuation, regardless of their BMI status at visit 1. However, the BMI z score for BA showed an increasing trend during GnRHa treatment and a decreasing trend after discontinuation. Therefore, long-term follow-up of BMI changes among girls with CPP is required until they attain adult height.

Abstract
BACKGROUND Obesity is caused by an imbalance between energy intake, i.e. eating and energy expenditure (EE). Severe obesity is more prevalent in women than men worldwide, and obesity pathophysiology and the resultant obesity-related disease risks differ in women and men. The underlying mechanisms are largely unknown. Pre-clinical and clinical research indicate that ovarian hormones may play a major role. OBJECTIVE AND RATIONALE We systematically reviewed the clinical and pre-clinical literature on the effects of ovarian hormones on the physiology of adipose tissue (AT) and the regulation of AT mass by energy intake and EE. SEARCH METHODS Articles in English indexed in PubMed through January 2016 were searched using keywords related to: (i) reproductive hormones, (ii) weight regulation and (iii) central nervous system. We sought to identify emerging research foci with clinical translational potential rather than to provide a comprehensive review. OUTCOMES We find that estrogens play a leading role in the causes and consequences of female obesity. With respect to adiposity, estrogens synergize with AT genes to increase gluteofemoral subcutaneous AT mass and decrease central AT mass in reproductive-age women, which leads to protective cardiometabolic effects. Loss of estrogens after menopause, independent of aging, increases total AT mass and decreases lean body mass, so that there is little net effect on body weight. Menopause also partially reverses women's protective AT distribution. These effects can be counteracted by estrogen treatment. With respect to eating, increasing estrogen levels progressively decrease eating during the follicular and peri-ovulatory phases of the menstrual cycle. Progestin levels are associated with eating during the luteal phase, but there does not appear to be a causal relationship. Progestins may increase binge eating and eating stimulated by negative emotional states during the luteal phase. Pre-clinical research indicates that one mechanism for the pre-ovulatory decrease in eating is a central action of estrogens to increase the satiating potency of the gastrointestinal hormone cholecystokinin. Another mechanism involves a decrease in the preference for sweet foods during the follicular phase. Genetic defects in brain α-melanocycte-stimulating hormone-melanocortin receptor (melanocortin 4 receptor, MC4R) signaling lead to a syndrome of overeating and obesity that is particularly pronounced in women and in female animals. The syndrome appears around puberty in mice with genetic deletions of MC4R, suggesting a role of ovarian hormones. Emerging functional brain-imaging data indicates that fluctuations in ovarian hormones affect eating by influencing striatal dopaminergic processing of flavor hedonics and lateral prefrontal cortex processing of cognitive inhibitory controls of eating. There is a dearth of research on the neuroendocrine control of eating after menopause. There is also comparatively little research on the effects of ovarian hormones on EE, although changes in ovarian hormone levels during the menstrual cycle do affect resting EE. WIDER IMPLICATIONS The markedly greater obesity burden in women makes understanding the diverse effects of ovarian hormones on eating, EE and body adiposity urgent research challenges. A variety of research modalities can be used to investigate these effects in women, and most of the mechanisms reviewed are accessible in animal models. Therefore, human and translational research on the roles of ovarian hormones in women's obesity and its causes should be intensified to gain further mechanistic insights that may ultimately be translated into novel anti-obesity therapies and thereby improve women's health.

Abstract
PURPOSE This study aimed to investigate the influence of gonadotropin releasing hormone agonist (GnRHa) treatment on the weight and body mass index (BMI) of girls who were diagnosed with idiopathic central precocious puberty (CPP) or early puberty (EP). METHODS Patients who were younger than 8 years of age at diagnosis were classified as CPP and patients aged between 8 and 9 years at diagnosis were classified as EP. Of 129 patients, 34 were diagnosed with CPP and 95 were diagnosed with EP. The patients were divided according to pretreatment weight status into normal weight group, an overweight group, or an obese group. RESULTS No significant changes were observed with respect to the weight standard deviation score (SDS) before and after 1 year, 2 years of treatment, respectively (P>0.05, P>0.05) in all patient groups. No significant changes were observed in relation to the BMI SDS before and after 1 year, 2 years of treatment, respectively (P>0.05, P>0.05) in all patient group. Depending on the degree of obesity, differences with respect to the weight SDS and BMI SDS were observed. CONCLUSION BMI SDS increased in the GnRHa-treated patients as a whole group, but was not statistically significant. But BMI SDS increased significantly in the normal weight group after 2 years of GnRHa treatment. So, GnRHa treatment may affect the change of BMI SDS depending on degree of obesity.

Abstract
BACKGROUND/AIMS Gonadotropin-releasing hormone analogues (GnRHa) represent the gold standard treatment for central precocious puberty (CPP). We aimed to assess the effects of GnRHa treatment on metabolic outcomes, bone status, and polycystic ovary syndrome (PCOS) prevalence in young girls with idiopathic CPP (ICPP). METHODS We enrolled 94 ICPP girls who were at least 2 years after menarche and had already attained adult height at the time of the study: 56 previously treated with depot triptorelin (3.4 ± 0.6 years) and 38 untreated. Auxological parameters, lipid profile, homeostatic model assessment of insulin resistance (HOMA-IR), bone state, and prevalence of PCOS were assessed. RESULTS The 2 groups were similar for body mass index (BMI) and waist circumference. HOMA-IR, dehydroepi-androsterone sulfate, and Δ4-androstenedione were higher in the treated than in the untreated subjects (p < 0.001). Significant differences were found for amplitude-dependent speed of sound (p < 0.03) and bone transmission time z-scores (p < 0.01). The prevalence of PCOS was higher in the treated than in the untreated subjects (p < 0.04). CONCLUSION GnRHa therapy is associated with hyperandrogenism and an increase in insulin resistance and PCOS prevalence, but not with increased BMI or lipid profile alterations. Long-term evaluations at the time of expected peak bone mass achievement are needed to understand the persistent or transient nature of subtle bone abnormalities.

Abstract
BACKGROUND The influence of gonadotropin-releasing hormone analogue (GnRHa) treatment on body mass index (BMI) evolution in girls with idiopathic central precocious puberty (CPP) is unclear. Hence, we aimed to evaluate the effect of GnRHa treatment on BMI-standard deviation score (SDS) from diagnosis of idiopathic CPP until adult height. METHODS An observational study of girls diagnosed with CPP in Spain was carried out between January 2008 and December 2014. A computer program was designed to process clinical and biological data from patients treated in 55 departments of pediatric endocrinology throughout the country. The inclusion criteria were (1) girls diagnosed with CPP before 8 years of age; (2) born after 1992; (3) with a difference between bone and chronological age of at least 1 year, and (4) with a luteinizing hormone peak >7 U/l during luteinizing hormone-releasing hormone testing. The influence of GnRHa treatment on BMI-SDS evolution was analyzed. RESULTS Data from 333 girls (22.2% adopted) were evaluated. We report follow-up data at 6, 12, 24, 36, 48 and 60 months and adult height from 269, 232, 198, 153, 105, 56 and 49 girls, respectively. During treatment, there was an increase in BMI-SDS of 0.43 ± 1.17 (95% CI: 0.20-0.64). At adult height (n = 49), BMI-SDS was 1.51 ± 1.38, which was 0.60 ± 1.09 higher than at diagnosis (95% CI: 0.43-0.75). CONCLUSIONS During treatment with GnRHa, girls experience a significant increase in BMI-SDS that persists after therapy is stopped and adult height has been reached. © 2016 S. Karger AG, Basel.

Abstract
PURPOSE The effects of gonadotropin-releasing hormone agonist (GnRHa) treatment on body mass index (BMI) are controversial in girls with central precocious puberty (CPP). We therefore evaluated auxological parameters during GnRHa therapy in patients with CPP, specifically focusing on changes in BMI. METHODS Seventy-seven girls with idiopathic CPP who underwent GnRHa therapy were retrospectively recruited. We investigated BMI changes during the treatment period after stratifying them according to baseline BMI status as follows: normal (BMI percentile of <85th) and overweight groups (BMI percentile of ≥85th). RESULTS The incidence of overweight/obesity (40.3%/23.4%) was very high in the girls with CPP. In the overall study population, no significant BMI change was observed during the GnRHa treatment period. However, when stratified according to baseline BMI status, the normal-weight group showed a significant increase in BMI-standard deviation score (SDS), whereas the overweight group showed no change in BMI-SDS. Baseline BMI-SDS was an independent predictor of changes in BMI during the GnRHa treatment period. Changes in weight-SDS were similar, but changes in height-SDS were significantly greater in the overweight group than in the normal-weight group, which explains the observed difference in BMI-SDS. CONCLUSION Our results demonstrate that the difference in the pattern of BMI changes among our CPP patients suggests that delayed puberty induced by GnRHa treatment may have different effects on linear growth according to baseline body composition. This study underscores the importance of individualized lifestyle intervention in CPP children.

Effect of pubertal suppression and cross-sex hormone therapy on bone turnover markers and bone mineral apparent density (BMAD) in transgender adolescents. Bone 2017; 95:11-19. [PMID: 27845262 DOI: 10.1016/j.bone.2016.11.008] [Citation(s) in RCA: 102] [Impact Index Per Article: 14.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2016] [Revised: 11/02/2016] [Accepted: 11/06/2016] [Indexed: 12/17/2022]
Abstract
Puberty is highly important for the accumulation of bone mass. Bone turnover and bone mineral density (BMD) can be affected in transgender adolescents when puberty is suppressed by gonadotropin-releasing hormone analogues (GnRHa), followed by treatment with cross-sex hormone therapy (CSHT). We aimed to investigate the effect of GnRHa and CSHT on bone turnover markers (BTMs) and bone mineral apparent density (BMAD) in transgender adolescents. Gender dysphoria was diagnosed based on diagnostic criteria according to the DSM-IV (TR). Thirty four female-to-male persons (transmen) and 22 male-to-female persons (transwomen)were included. Patients were allocated to a young (bone age of <15years in transwomen or <14 in transmen) or old group (bone age of ≥15years in transwomen or ≥14years in transmen). All were treated with GnRHa triptorelin and CSHT was added in incremental doses from the age of 16years. Transmen received testosterone esters (Sustanon, MSD) and transwomen received 17-β estradiol. P1NP, osteocalcin, ICTP and BMD of lumbar spine (LS) and femoral neck (FN) were measured at three time points. In addition, BMAD and Z-scores were calculated. We found a decrease of P1NP and 1CTP during GnRHa treatment, indicating decreased bone turnover (young transmen 95% CI -74 to -50%, p=0.02, young transwomen 95% CI -73 to -43, p=0.008). The decrease in bone turnover upon GnRHa treatment was accompanied by an unchanged BMAD of FN and LS, whereas BMAD Z-scores of predominantly the LS decreased especially in the young transwomen. Twenty-four months after CSHT the BTMs P1NP and ICTP were even more decreased in all groups except for the old transmen. During CSHT BMAD increased and Z-scores returned towards normal, especially of the LS (young transwomen CI 95% 0.1 to 0.6, p=0.01, old transwomen 95% CI 0.3 to 0.8, p=0.04). To conclude, suppressing puberty by GnRHa leads to a decrease of BTMs in both transwomen and transmen transgender adolescents. The increase of BMAD and BMAD Z-scores predominantly in the LS as a result of treatment with CSHT is accompanied by decreasing BTM concentrations after 24months of CSHT. Therefore, the added value of evaluating BTMs seems to be limited and DXA-scans remain important in follow-up of bone health of transgender adolescents.

Abstract
UNLABELLED This study assessed the prevalence and types of fractures in spina bifida and examined risk factors for fracture. Fracture prevalence was highest in childhood and reduced in adolescence and young adulthood. The importance of maintaining mobility is highlighted by the increased risk of fracture in those who are non-ambulatory. INTRODUCTION The aims of this study are to study the prevalence and types of fractures according to age group in spina bifida and examine risk factors associated with fracture. METHODS This is a retrospective cohort study of 146 individuals with spina bifida aged 2 years or older who attended the paediatric or adult spina bifida multidisciplinary clinic at a single tertiary hospital. RESULTS Median age at which first fracture occurred was 7 years (interquartile range 4-13 years). Fracture rates in children (ages 2-10), adolescents (ages 11-18) and adults (age > 18) were 10.9/1000 (95 % confidence interval 5.9-18.3), 5.4/1000 (95 % CI 1.5-13.8) and 2.9/1000 (95 % CI 0.6-8.1) patient years respectively. Childhood fractures predominantly involved the distal femur and femoral shaft; these fractures were rarely seen in adulthood. Non-ambulatory status was associated with a 9.8 times higher risk of fracture compared with ambulatory patients (odds ratio 9.8, p = 0.016, 95 % CI 1.5-63.0). Relative risk of re-fracture was 3.1 (95 % CI 1.4-6.8). Urological intervention with intestinal segments was associated with renal calculi (p = 0.037) but neither was associated with fracture. CONCLUSIONS The risk of fracture is lower in adults compared with children with spina bifida. The predominant childhood fracture affects the distal femur, and immobility is the most significant risk factor for fracture. Clinical factors contributing to fracture risk need to be elucidated to enable selection of patients who require investigation and treatment of osteoporosis.

Abstract
Gonadotropin-releasing hormone agonists (GnRHa) have been widely used for decades to treat patients with central precocious puberty (CPP). Several studies have investigated changes in body composition in patients with CPP following GnRHa treatment, but the results are inconsistent. The aim of this study was to investigate changes in body mass index (BMI) in children treated with GnRHa for 2 years. We also assessed whether BMI affects treatment outcomes. This study included 383 girls (214 girls with central precocious puberty and 169 girls who underwent early puberty) treated with depot leuprolide acetate monthly for at least 2 years. We analyzed changes in BMI standard deviation score (SDS). Furthermore, blood luteinizing hormone (LH) levels were determined 30 min after depot leuprolide acetate administration every 6 months to evaluate adequate suppression of the hypothalamic-pituitary-gonadal axis. Pretreatment mean BMI SDS values were 0.07 ± 0.69, 1.29 ± 0.16, and 1.95 ± 0.32 in the normal weight, overweight, and obese subjects, respectively. Mean BMI SDS values after 2 years of treatment increased significantly only in normal weight children (0.07 ± 0.69 vs. 0.25 ± 0.73, P < 0.001). LH levels 30 min after leuprolide injection after 2 years of treatment were not different among normal weight, overweight, and obese subjects. Although the difference in BMI SDS was relatively small, it standard deviation score increased significantly after 2 years of treatment in normal weight girls with early pubertal development.

Abstract
BACKGROUND In girls with Idiopathic Central Precocious Puberty (ICPP) concern has been raised by the potential impact of GnRH-analogues (GnRHa) treatment on body weight. We evaluated the effect of GnRHa on Body Mass Index (BMI) in girls with ICPP according to weight status at diagnosis. METHODS One hundred seventeen ICPP girls were divided according to pretreatment weight status in: normal weight (NW), overweight (OW) and obese (OB). BMI at one and two years of treatment was assessed. BMI-SDS of 60 patients who reached adult height (AH) was compared to that of 33 ICPP untreated girls. RESULTS NW girls significantly increased their baseline BMI-SDS at 1 and 2 years of treatment. OW girls only had a significant increment at one year of treatment while OB girls showed no BMI-SDS change. Patients evaluated at AH (at least four years after GnRHa withdrawal) showed a significant decrease on BMI compared to baseline and a significantly lower BMI than the untreated group. CONCLUSION In ICPP girls the BMI increase under GnRHa was inversely related to the pretreatment weight status. In the long term follow-up, no detrimental effect of GnRHa on body weight was observed. BMI-SDS was lower in treated than in untreated girls.

Abstract
STUDY OBJECTIVES To evaluate bone quantity and quality in postmenarchal adolescents treated for idiopathic central precocious puberty (CPP) in childhood with a gonadotropin-releasing hormone analog (GnRHa) and to determine the serum concentrations of bone remodeling markers. DESIGN AND PARTICIPANTS This cross-sectional study included 53 postmenarchal adolescent girls who were divided into 2 groups: 27 adolescents who were treated with GnRHa in childhood for idiopathic CPP (the CPP group) and 26 women who presented with physiological development of secondary sex traits (the control group). INTERVENTIONS None. MAIN OUTCOME MEASURES Weight, height, body mass index, age at menarche, time since menarche, body composition, bone mineral density (BMD), bone quality, and serum insulin, glucose, osteocalcin, and carboxyl-terminal telopeptide of type I collagen concentrations were compared in the 2 groups. BMD data were analyzed by using both dual-energy x-ray absorptiometry (DXA) and osteosonography, and body composition was measure with the use of DXA and electrical bioimpedance. RESULTS BMD and bone quality did not differ significantly between the CPP and control groups when analyzed by using DXA or osteosonography. Serum osteocalcin concentration was significantly lower (P = .02) in the CPP than in the control group. Insulin was higher in the CPP group, and hyperinsulinemia was an independent predictor of bone quantity and quality assessed by using osteosonography. Body mass index and percent fat were determined by using DXA, and the duration of use of GnRHa treatment and the time since GnRHa discontinuation were not independent predictors of bone quantity and quality. CONCLUSION Postmenarchal adolescents treated with GnRHa for CPP in childhood did not show a reduction in bone quantity or quality.

Abstract
AIM Leuprolide acetate is a gonadotropin-releasing hormone (GnRH) analogue frequently used in the treatment of central precocious puberty. Research is currently taking place into its effects on endocrine systems. The aim of this study is to investigate the effect of leuprolide acetate on vitamin D and bone mineral density. METHODS Twenty-three children diagnosed with central precocious puberty and receiving leuprolide acetate therapy for at least 12 months, and a control group of 17 healthy children were enrolled. In the study group, calcium, phosphorus, alkaline phosphatase, parathormone and 25-hydroxy vitamin D levels and bone mineral density were measured. The results were compared with those of the control group. RESULTS 25-Hydroxy vitamin D levels in the study and control groups were 15.17 ± 7 mg/dL and 22.2 ± 6.1 mg/dL, respectively (p < 0.05). In terms of bone mineral density, osteopenia was determined in 13 (56.5%) patients in the study group and osteoporosis in one (4.3%), while osteopenia was identified in seven patients in the control group, with no osteoporosis being identified (p > 0.05). CONCLUSION Gonadotropin-releasing hormone agonists may have an adverse effect on bone health. They may exhibit these effects by impacting on vitamin D levels. These levels should be periodically monitored in patients receiving treatment, and vitamin D support should be given in cases where the deficiency is identified.

Abstract
Besides growth hormone, several pharmaceutical products have been investigated for efficacy and safety in increasing short term growth or adult height. Short-term treatment with testosterone esters in boys with constitutional delay of growth and puberty is efficacious in generating secondary sex characteristics and growth acceleration. The addition of oxandrolone to growth hormone (GH) in Turner syndrome has an additive effect on adult height gain. Treatment with GnRH analogs is the established treatment of central precocious puberty, and its addition to GH therapy appears effective in increasing adult height in GH deficient children, and possibly short children born SGA or with SHOX deficiency, who are still short at pubertal onset. Aromatase inhibitors appear effective in several rare disorders, but their value in increasing adult height in early pubertal boys with GH deficiency or idiopathic short stature is uncertain. A trial with a C-natriuretic peptide analog offers hope for children with achondroplasia.

Abstract
OBJECTIVE The study aimed to assess the effect of gonadotropin-releasing hormone (GnRH) agonist therapy on body mass index (BMI) and growth in girls diagnosed with idiopathic central precocious puberty (CPP). MATERIALS AND METHODS Hospital records of 32 girls with idiopathic CPP who have been receiving GnRH agonist therapy for at least 12 months were retrospectively reviewed and auxological, clinical and laboratory parameters of the patients were recorded. BMI, body mass index standard deviation score (BMI SDS) for chronological age body mass index standard deviation score (CA-BMI SDS), BMI SDS for bone age body mass index standard deviation score (BA-BMI SDS), ratios of obesity and overweight were assessed before treatment and on the 12(th) month of therapy in patients diagnosed with idiopathic CPP. RESULTS The study comprised of 32 girls diagnosed with idiopathic CPP. BMI values showed statistically significant increase in the 1(st) year of treatment (19.16 ± 2.8 vs. 20.7 ± 3.4, P = 0.001). Despite a mild increase in CA-BMI SDS in the 1(st) year of treatment versus before treatment, it was no statistically significant (1.0 ± 0.8 vs. 1.1 ± 0.9, P = 0.061). However, significant increase was observed in BA-BMI SDS in the 1(st) year of treatment versus before treatment (0.8 ± 0.7 vs. 0.4 ± 0.8, P < 0.001). Before treatment, 37.5% (12/32) of the patients were overweight and 21.9% (5/32) were obese, whereas in the 1(st) year, 34.4% (11/32) of the patients were overweight and 31.3% were obese (P = 0.001). CONCLUSION Whilst 1/3 of the cases diagnosed with idiopathic CPP were overweight and obese at the time of diagnosis, GnRH agonist therapy caused statistically significant weight gain in patients diagnosed with CPP. Therefore, these patients should be closely monitored and weight control should be provided by diet and exercise programs in the course of treatment.

Kim EY. Long-term effects of gonadotropin-releasing hormone analogs in girls with central precocious puberty. KOREAN JOURNAL OF PEDIATRICS 2015; 58:1-7.

Abstract
Gonadotropin-releasing hormone analogs (GnRHa) are widely used to treat central precocious puberty (CPP). The efficacy and safety of GnRHa treatment are known, but concerns regarding long-term complications are increasing. Follow-up observation results after GnRHa treatment cessation in female CPP patients up to adulthood showed that treatment (especially <6 years) was beneficial for final adult height relative to that of pretreated or untreated patients. Puberty was recovered within 1 year after GnRHa treatment discontinuation, and there were no abnormalities in reproductive function. CPP patients had a relatively high body mass index (BMI) at the time of CPP diagnosis, but BMI standard deviation score maintenance during GnRHa treatment seemed to prevent the aggravation of obesity in many cases. Bone mineral density decreases during GnRHa treatment but recovers to normal afterwards, and peak bone mass formation through bone mineral accretion during puberty is not affected. Recent studies reported a high prevalence of polycystic ovarian syndrome in CPP patients after GnRHa treatment, but it remains unclear whether the cause is the reproductive mechanism of CPP or GnRHa treatment itself. Studies of the psychosocial effects on CPP patients after GnRHa treatment are very limited. Some studies have reported decreases in psychosocial problems after GnRHa treatment. Overall, GnRHa seems effective and safe for CPP patients, based on long-term follow-up studies. There have been only a few long-term studies on GnRHa treatment in CPP patients in Korea; therefore, additional long-term follow-up investigations are needed to establish the efficacy and safety of GnRHa in the Korean population.

Abstract
The timing of puberty has considerable biological, psychosocial and long-term health implications. Secular trends in age at pubertal development, the effects of obesity and the potential effects of environmental endocrine disruptors challenge the standard definitions of precocious puberty and the indications for intervention with gonadotropin-releasing hormone agonists (GnRHa) in girls with precocious puberty. GnRHa therapy is effective in improving adult height in patients who present with classic central precocious puberty (at <8 years old), without causing adverse effects on body composition, BMD and reproductive function. However, its benefits in patients with atypical forms of early puberty not driven by luteinising hormone are not well defined. The role of GnRHa in these patients and the potential benefits in terms of later growth, psychosocial functioning and long-term risk of adult diseases that are associated with early menarche, such as breast cancer and the metabolic syndrome, have not been established.

Abstract
OBJECTIVES 1. To determine BMI, obesity/overweight rates, glucose and lipids at baseline, during GnRHa treatment and shortly after therapy discontinuation in female children with CPP and EP. 2. To compare this response to that seen in a similar group of untreated patients. METHODS A retrospective analysis of 71 children with either CPP (n = 37) or EP (n = 34) was undertaken. Forty three were treated with a GnRHa for at least 2 years, while 28 were followed without treatment. RESULTS At the time of diagnosis, a higher BMI (z-score of 1.1 ± 0.8 vs. 0.6 ± 0.7, p = 0.004) and a higher prevalence of obesity/overweight (72.9 vs. 35.3%, p = 0.001) was observed in subjects with CPP when compared to those with EP. Children with EP had higher fasting glucose and total cholesterol than those with CPP. BMI z-score, obesity/overweight rates, fasting glucose and lipids did not change significantly in girls with CPP or EP during 3 yrs of follow up, regardless of treatment. Weight z-scores were higher at 3 years in treated than in untreated girls with CPP (p = 0.02), while it was higher in untreated than in GnRHa-treated patients with EP at baseline, 1, 2 and 3 years (p = 0.007, p = 0.002, p = 0.02 and p = 0.04, respectively) and remained so shortly after stopping therapy (p = 0.03). CONCLUSIONS There is a high prevalence of obesity/overweight in girls with CPP and EP at diagnosis. However, this risk is greater in CPP than in EP girls. BMI, Obesity/overweight rates, fasting glucose and lipids remained stable in CPP and EP girls regardless of therapy. Weight z-scores were found to be higher in treated CPP girls and in untreated girls with EP.

Abstract
OBJECTIVE To compare final height, change in body mass index (BMI), and time from end of treatment until menarche in girls with central precocious puberty treated with the histrelin implant versus depot gonadotropin releasing hormone agonist injections. STUDY DESIGN Chart review, interview, and final height measurements of 2 groups of girls with central precocious puberty; triptorelin depot (TD) group: 23 girls were treated from age 8.4 ± 0.3 with monthly injections of TD, for 26.7 ± 2.5 months; histrelin implant group: 11 girls were treated from age 8.7 ± 0.3 years for 28.4 ± 3.7 months, of whom 9 initially received monthly TD injections for 1.5-39 months. Final height, BMI (pretreatment vs recent), and time between either implant removal or last injection to menarche were compared. RESULTS Time between removal of implant or last injection and menarche was 9.3 ± 1.5 (histrelin implant group) versus 16.1 ± 1.7 (TD group) months (P = .02). Predicted height at implant insertion was 156.8 ± 2.6 cm, and final height was 161.1 ± 2.0 cm (not significant [NS]). Predicted height for TD was 155.2 ± 1.9 cm and final height was 157.9 ± 1.7 cm (NS). Change from onset of treatment to final BMI-SDS for histrelin implant was -0.41 ± 0.3, and for TD was -0.03 ± 0.2 (NS). CONCLUSIONS Menarche occurred sooner after implant removal. There was no difference in final height or BMI outcomes between the 2 treatment modalities.

Abstract
INTRODUCTION GnRH analogs represent the drug of choice for medical treatment of central precocious puberty (CPP). They provided prompt and reversible suppression of reproductive axis and several reports have shown that adult height is preserved in treated children. AREAS COVERED This review updates GnRH analog treatment in CPP by a search of the literature published on the topic since 1980. EXPERT OPINION Monthly GnRH analogs are currently considered the 'gold standard' for the medical treatment of CPP, since a lot of experience is accumulated on their use in children. Differences in long-term outcome (in terms of adult height) are reported and they may be due to differences in selection criteria, treatment monitoring, criteria to stop of therapy, different biological activity of the various drugs and different genetic background of treated patients; altogether, these items remain poorly evaluated. Psychological indications for treatment and long-term psychological outcome of treated children should be better addressed. Comparative trials among the various GnRH analogs are very scarce. New very long-acting GnRH analogs (quarterly or yearly formulations) may improve compliance with therapy, but longer follow-up studies are needed. Medical treatment of CPP should be close to pediatric endocrinologists or tertiary pediatric endocrinology centers with documented experience in this field.

Abstract
It has been proven for more than two decades that gonadotropin releasing hormone analogue therapy is the only choice of treatment in patients with central precocious puberty. Aims: The aim of the authors was to assess the effect of gonadotropin releasing hormone analogue treatment on final height, body mass index, bone mineral density and ovarian function in girls with idiopathic central precocious puberty. Methods: Predicted adult height, target height and achieved height due to therapy was assessed in 15 girls with idiopathic precocious puberty treated with gonadotropin releasing hormone analogue. At the beginning of the treatment, the age of the girls was 7.0±0.8 years (mean±SD) and at the end of the treatment 12±0.8 years. The duration of gonadotropin-releasing hormone analogue treatment was 4.48±0.8 years. At the time of achieving final height, the age of the patients was 18.2±2.0 years and the height was 160.4±7.1 cm. When final height was reached, the authors evaluated bone mineral density Z-score values, levels of bone markers and the function of the hypothalamic-pituitary-gonadal axis. 15 healthy prepubertal girls, 15 pubertal girls and 15 girls who reached final height matched for chronological age were selected as control groups. Results: The majority of the gonadotropin releasing hormone-treated girls reached or almost reached their expected height predicted on the basis of the heights of their parents, but the therapy resulted only in a modest beneficial effect on height gain. Despite the fact that the body weight of patients increased during the treatment, there was no significant difference in their body mass index when they reached their final height as compared to controls. As compared to controls, patients had a decreased bone mineral density at the time when they reached their final height (lumbar spine 2-4 Z score, –0.27±1.2 vs. 0.5±0.7 in controls; p = 0.0377), which could be explained by their overweight that already existed before treatment, lack of exercise and poor calcium uptake. Their menarche occurred 12±4.6 months after discontining the treatment. Conclusions: Gonadotropin releasing hormone analogue therapy exerts a modest beneficial effect on final height gain. There are no detrimental effects on body mass index, bone mineral density and ovarian function after treatment. Side-effects are of minor severity and they are tolerable. Orv. Hetil., 2012, 153, 418–424.

Abstract
OBJECTIVES Idiopathic central precocious puberty and its postponement with a (gonadotropin-releasing hormone) GnRH agonist are complex conditions, the final effects of which on bone mass are difficult to define. We evaluated bone mass, body composition, and bone remodeling in two groups of girls with idiopathic central precocious puberty, namely one group that was assessed at diagnosis and a second group that was assessed three years after GnRH agonist treatment. METHODS The precocious puberty diagnosis and precocious puberty treatment groups consisted of 12 girls matched for age and weight to corresponding control groups of 12 (CD) and 14 (CT) girls, respectively. Bone mineral density and body composition were assessed by dual X-ray absorptiometry. Lumbar spine bone mineral density was estimated after correction for bone age and the mathematical calculation of volumetric bone mineral density. CONEP: CAAE-0311.0.004.000-06. RESULTS Lumbar spine bone mineral density was slightly increased in individuals diagnosed with precocious puberty compared with controls; however, after correction for bone age, this tendency disappeared (CD = -0.74 + 0.9 vs. precocious puberty diagnosis = -1.73 + 1.2). The bone mineral density values of girls in the precocious puberty treatment group did not differ from those observed in the CT group. CONCLUSION There is an increase in bone mineral density in girls diagnosed with idiopathic central precocious puberty. Our data indicate that the increase in bone mineral density in girls with idiopathic central precocious puberty is insufficient to compensate for the marked advancement in bone age observed at diagnosis. GnRH agonist treatment seems to have no detrimental effect on bone mineral density.

Abstract
Precocious puberty poses significant diagnostic and therapeutic challenge to the physician. Recent advances in the understanding of pathophysiology of precocious puberty have resulted in improved management. Timely intervention is mandatory to achieve successful outcome. The identification of critical role of KISS-1-kisspeptin-GPR54 system has gone a long way to provide an insight into pubertal physiology. It is likely that the system would become an important diagnostic and therapeutic target in children with precocious puberty. Epidemiological studies point toward earlier thelarche. This is, however, associated with slower progression as the age of menarche is static. These changes have led to suggestions of lowering the age cutoffs for precocious puberty in girls. New developments in assessment of precocious puberty including gonadotropin releasing hormone (GnRH) agonist test have made characterization of precocious puberty easier. Longstanding GnRH analogs have become the mainstay of treatment of gonadotropin-dependent precocious puberty, while aromatase inhibitors and inhibitors of sex hormone action are increasingly being used in gonadotropin-independent precocious puberty.

Abstract
CONTEXT Early menarche is associated with increased risk of cardiovascular disease in adulthood. It is unknown whether metabolic risk factors are adversely affected in girls with central precocious puberty (CPP) already at time of diagnosis. OBJECTIVE The objective of the study was to evaluate metabolic profiles in girls with early normal puberty (EP) and CPP. DESIGN AND SETTING This was a combined cross-sectional and longitudinal study at a tertiary center of pediatric endocrinology. PATIENTS AND INTERVENTION Twenty-three girls with EP or CPP and 115 controls with normal pubertal timing were evaluated by oral glucose tolerance test, dual-energy x-ray absorptiometry scan, and fasting blood samples. Fifteen girls (13 CPP) were treated with GnRH agonists (GnRHa) and reevaluated after 12 and 52 wk of treatment. MAIN OUTCOME MEASURES Insulin and glucose levels during oral glucose tolerance test and fasting lipid levels were measured. RESULTS At the time of diagnosis, girls with CPP had higher fasting insulin, triglyceride, and low-density lipoprotein-cholesterol levels as well as lower insulin sensitivity and high-density lipoprotein/total cholesterol ratios (all P<0.05) compared with controls after adjustment for pubertal stage and body fat percentage. Age at pubertal onset positively predicted insulin sensitivity for a given pubertal stage (P=0.04) in girls with EP and CPP. Insulin sensitivity decreased significantly during 1 yr of GnRHa treatment (P=0.04). CONCLUSIONS Girls with CPP had adverse metabolic profiles at the time of diagnosis compared with puberty-matched controls. In addition, those with the earliest onset of puberty had the most adverse metabolic profiles. Surprisingly, metabolic profiles deteriorated even further after withdrawal of sex steroids by GnRHa treatment.
