Abstract With the decline in 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 cut-offs for evaluation of precocious puberty should not differ substantially from those used for non-obese 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 MRI 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 counselling 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 Objectives Longer-acting gonadotropin-releasing hormone analogs (GnRHa) have been widely used for central precocious puberty (CPP) treatment. However, the follow-up of patients after this treatment are still scarce. Our aim was to describe anthropometric, metabolic, and reproductive follow-up of CPP patients after treatment with leuprorelin acetate 3-month depot (11.25 mg). Methods Twenty-two female patients with idiopathic CPP were treated with leuprorelin acetate 3-month depot (11.25 mg). Their medical records were retrospectively evaluated regarding clinical, hormonal, and imaging aspects before, during, and after GnRHa treatment until adult height (AH). Results At the diagnosis of CPP, the mean chronological age (CA) was 8.2 ± 1.13 year, and mean bone age (BA) was 10.4 ± 1.4 year. Mean height SDS at the start and the end of GnRHa treatment was 1.6 ± 0.8 and 1.3 ± 0.9, respectively. The mean duration of GnRHa treatment was 2.8 ± 0.8 year. Mean predicted adult heights (PAH) at the start and the end of GnRH treatment was 153.2 ± 8.6 and 164.4 ± 7.3 cm, respectively (p<0.05). The mean AH was 163.2 ± 6.2 cm (mean SDS: 0.1 ± 1). All patients were within their target height (TH) range. There was a decrease in the percentage of overweight and obesity from the diagnosis until AH (39–19% p>0.05). At the AH, the insulin resistance and high LDL levels were identified in 3/17 patients (17.6%) and 2/21 patients (9.5%), respectively. The mean CA of menarche was 12.2 ± 0.5 years. At the AH, PCOS was diagnosed in one patient (4.8%). Conclusions Long-term anthropometric, metabolic, and reproductive follow-up of patients with CPP treated with longer-acting GnRHa revealed effectivity, safety, and favorable outcomes.

Abstract. In 12 patients (11 girls, 1 boy) with central precocious puberty and 4 patients (3 girls, 1 boy) with idiopathic short stature treated for 1 year with a GnRH superagonist, buserelin (0.3 mg intranasally, 4 times a day), a variable degree of inhibition of sex steroid secretion and pubertal development was observed. Regression of breast or genital development required a daily dosage of buserelin ≥ 34 μg/kg. After 3, 6, 9 and 12 months of treatment, the serum oestradiol level in the girls was positively related (r = 0.69) to basal serum LH measured at the same time and to change in breast development during the previous 3 months. In contrast, LH response to GnRH was very low in all the patients and not related to the degree of oestradiol inhibition. Height velocity and bone age velocity during the year of treatment showed no significant correlation with mean oestradiol level. Bone age velocity during treatment was inversely related to bone age at onset of buserelin. These data show that 1) the pituitary gonadal suppression during intranasal administration of buserelin is variable and dose-dependent; 2) gonadotropin response to GnRH is not a sensitive indicator of incomplete pituitary suppression during buserelin treatment; and 3) bone age velocity during treatment is more reduced the more advanced bone age is at onset of treatment.

Sexual Characteristics

Precocious puberty is defined as the onset of secondary sexual characteristics before 8 years of age in girls and 9 years in boys. Central Precocious Puberty (CPP) is caused by early activation of the hypothalamic-pituitary-gonadal axis. Laboratory test of LH, FSH, and Estradiol is recommended for monitoring suppressive effects from GnRHa therapy in the early three months and every six months. This study aimed to report a case of CPP in a 3-year and 3-month-old girl. A 3-year and 3-month-old girl went to the hospital with vaginal bleeding (menstruation), breast development, and pubic and axilla hair for 7-month-old. Physical examination found moderately ill with obesity, body weight 20 kg, height 98 cm. Tanner stage was A2M3P2, café au lait was found in the left forehead with size 7x3.5 cm. In March 2015 before GnRHa therapy, LH, FSH and Estradiol level increased with levels of 4.32 mlU/mL, 6.01 mlU/mL, and 67 pg/mL, and after 3 months of the treatment was 0.87 mlU/mL, 2.51 mlU/mL and <20 pg/mL. Pelvic ultrasonography showed suggestive precocious puberty, bone age 5-year and 9-month (Greulich and Pyle), CT-Scan of the brain showed hypothalamic tumor suspected hypothalamic hamartoma. This patient was treated with a GnRHa injection every 4 weeks. Leuprorelin is a synthetic non-peptide analogue of natural GnRH. The diagnosis was based on medical history, physical examination, laboratory, and radiological findings. The prognosis of the patient was good.

Abstract Background: Children with central precocious puberty (CPP) are treated with gonadotropin-releasing hormone agonists (GnRHa) to suppress puberty. Optimizing treatment outcomes continues to be studied. The relationships between growth, rate of bone maturation (bone age/chronological age [ΔBA/ΔCA]), luteinizing hormone (LH), predicted adult stature (PAS), as well as variables influencing these outcomes, were studied in children treated with depot leuprolide (LA Depot) Methods: Subjects (64 girls, seven boys) with CPP received LA Depot every 3 months for up to 42 months. Multivariate regression analyses were conducted to examine the predictors affecting ΔBA/ΔCA, PAS and growth rate. Results: Ninety percent of subjects (18 of 20) were suppressed (LH levels <4 IU/L) at 42 months. Over 42 months, the mean growth rate declined 2 cm/year, the mean BA/CA ratio decreased 0.21 and PAS increased 8.90 cm for girls (n=64). PAS improved to mid-parental height (MPH) in 46.2% of children by 30 months of treatment. Regression analysis showed that only the Body Mass Index Standardized Score (BMI SDS) was significantly associated (β+0.378 and +0.367, p≤0.05) with growth rate. For PAS, significant correlations were with MPH (β+0.808 and +0.791, p<0.001) and ΔBA/ΔCA (β+0.808 and +0.791, p<0.001). For ΔBA/ΔCA, a significant association was found only with BA at onset of treatment (β−0.098 and −0.103, p≤0.05). Peak-stimulated or basal LH showed no significant influence on growth rate, ΔBA/ΔCA or PAS. Conclusions: Growth rate and bone maturation rate normalized on treatment with LA Depot. LH levels were not significantly correlated with growth rate, ΔBA/ΔCA or PAS, suggesting that suppression was adequate and variations in gonadotropin levels were below the threshold affecting outcomes.

To explore the adoption of ultrasound imaging diagnosis based on deep learning of convolutional neural networks (CNNs) in the treatment of central precocious puberty (CPP) by gonadotropin-releasing hormone agonists (GnRHa), ultrasound imaging based on CNN was utilized to treat CPP. The bone age, uterine and ovarian volume, and breast development of incomplete precocious puberty (IPP) group and CPP group were observed and recorded. The peak values of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were measured. The uterine and ovarian volume before and after GnRHa treatment of CPP were compared. The results showed that the bone age (9.03 ± 1.07), uterine volume (2.37 ± 1.52), ovarian volume (2.36 ± 0.82 mL), and breast development of the CPP group were considerably higher in contrast to the IPP group and control group ( P < 0.05 ). The LH peak (11.97 ± 5.63) and FSH peak (12.89 ± 3.15) of the CPP group were substantially higher relative to the IPP group ( P < 0.05 ). The uterine volume (1.06 ± 0.42) and ovarian volume (1.12 ± 0.49) after treatment were inferior to those before treatment ( P < 0.05 ). In short, ultrasound images based on deep learning could diagnose precocious puberty, which could also provide a certain basis for GnRHa treatment of CPP, as well as an important basis for clinical diagnosis and treatment of precocious puberty.

Objective Gonadotropin-releasing hormone agonist (GnRHa) treatment improves the potential for gaining height in patients with central precocious puberty (CPP). However, most studies have focused on girls because CPP in boys is relatively rare. Therefore, we aimed to determine the effect of GnRHa treatment on auxological outcomes in boys with CPP. Methods Eighty-five boys with CPP were treated with leuprolide or triptorelin acetate 3.75 mg over 2 years. Anthropometry, bone age, sexual maturity rating, and predicted adult height (PAH) were assessed every 6 months. Furthermore, 20 boys were followed up after treatment discontinuation until achievement of the final adult height (FAH). Results The mean chronological age (CA) and bone age (BA) of the patients with CPP at treatment initiation were 9.5 ± 0.5 years and 11.7 ± 0.9 years, respectively. The mean duration of treatment was 2.87 ± 0.63 years. The PAH at treatment initiation was 172.1 cm (-0.23 ± 1.05 PAH standard deviation score). The PAH at treatment discontinuation (176.2 ± 6.6 cm) was significantly higher than the pretreatment PAH. In addition, the mean final adult height in the 20 boys who were followed up after discontinuation of treatment was 173.4 ± 5.8 cm, which was significantly higher than the initial PAH (170.1 ± 4.5 cm; p = 0.006). In multivariate analysis, the height gain (the difference between the FAH and PAH at treatment initiation) significantly correlated with the target height. Conclusion Long-term GnRHa treatment significantly improved the growth potential and FAH in boys with CPP.

Sexual Characteristics

We describe the case of a 6.5-year-old girl with central precocious puberty (CPP), which signifies the onset of secondary sexual characteristics before the age of eight in females and the age of nine in males as a result of stimulation of the hypothalamic-pituitary-gonadal axis. Her case is likely related to her adoption, as children who are adopted internationally have much higher rates of CPP. She had left breast development at Tanner Stage 2, adult body odor, and mildly advanced bone age. In order to halt puberty and maximize adult height, she was prescribed a gonadotropin releasing hormone analog, the first line treatment for CPP. She was administered Lupron (leuprolide acetate) Depot-Ped (3 months) intramuscularly. After her second injection, she developed swelling and muscle pain at the injection site on her right thigh. She also reported an impaired ability to walk. She was diagnosed with muscle fibrosis. This is the first reported case of muscle fibrosis resulting from Lupron injection.

Abstract Objectives Gonadotropin-releasing hormone agonist treatment is important for optimal growth in girls with central precocious puberty (CPP). Data are lacking regarding benefit to height outcome when treatment is started after chronological age (CA) of 7 years, and if continued beyond CA of 10 years or bone age (BA) of 12 years. Methods Forty-eight girls with CPP were treated with monthly leuprolide depot. Change in predicted adult height (PAH) during treatment was assessed. Changes in PAH and growth velocity were compared between girls initiating treatment at CA <7 vs. ≥7 years, and BA ≥12 vs. BA <12 years. Results Mean baseline CA was 6.8 years, BA, 10.2 years; and PAH, 156.4 cm. BA/CA ratio decreased from pretreatment values, averaging 1.5 to 1.2 at the end of treatment. Proportion of girls with >5 cm PAH change during treatment was similar, and PAH increased throughout treatment in most girls, regardless of age at treatment initiation. PAH continued to increase in 16/19 girls who continued treatment after BA of 12 years, and also in 16/22 girls who continued treatment after CA of 10 years. Conclusions PAH improved in most girls who initiated treatment after CA of 7 years. It continued to improve in most girls with longer treatment, even past BA of 12 years or CA of 10 years, which suggests that no absolute CA or BA limit should define initiation or end of treatment. Treatment plans need to be individualized, and neither treatment initiation nor cessation should be based on BA or CA alone.

Minimal Information

<b><i>Background:</i></b> A random ultrasensitive luteinizing hormone (LH) (LH-ICMA) ≥0.3 mIU/L is highly accurate in confirming a diagnosis of central precocious puberty (CPP). However, a prepubertal value does not exclude the diagnosis. The clinical differences between patients with CPP who have a pubertal versus prepubertal LH-ICMA have not been clearly defined. Furthermore, there is minimal information regarding the utility of this test in boys with CPP. The objective of this study was to analyze differences between patients diagnosed with CPP who had a pubertal versus prepubertal LH-ICMA, including a cohort of boys. <b><i>Methods:</i></b> A retrospective chart review of children diagnosed with CPP within the last 10 years who had a baseline LH-ICMA obtained was performed. Variables analyzed included sex, age, ethnicity, bone age, BMI, etiology, Tanner stage (TS), testicular volume, and menarchal status. <b><i>Results:</i></b> Of 27 boys and 126 girls who qualified for the study, the LH-ICMA was pubertal in 87% and prepubertal in 13%. Girls with a pubertal LH-ICMA had higher baseline estradiol concentrations (<i>p</i> &#x3c; 0.001) and more advanced breast development (<i>p</i> = 0.015) compared to girls with a prepubertal LH-ICMA. Of girls with a prepubertal LH-ICMA, 74% had at least TS 3 breast development and 1 was post-menarchal. The LH-ICMA was pubertal in 96% of the boys with CPP in this study. <b><i>Conclusions:</i></b> The LH-ICMA can be prepubertal even in girls with advanced development. To our knowledge, ours is the largest cohort of boys in whom the accuracy of a random LH-ICMA has been reported.
