Abstract Objectives The aim of this study was to evaluate the resilience of girls with central precocious puberty (CPP) during treatment with a gonadotropin-releasing hormone agonist (GnRHa) and compare these results with their healthy peers. Methods The Connor–Davidson Resilience Scale (CD-RISC) is a self-report scale used to quantify resilience, which is divided into seven subgroups (hardiness, coping, flexibility, purpose, optimism, regulation of emotion and cognition (REC), and self-efficacy). Fifty-one girls with CPP receiving GnRHa treatment and 51 healthy controls were involved in the study. Anthropometric measurements were evaluated and CD-RISC was performed at least six months after the initiation of GnRHa treatment. Results There was no statistically significant difference between the anthropometric evaluations of girls with CPP and the control group. Similarly, the total score and subgroup scores of patients with CPP and the control group showed no statistically significant difference. In the correlation analysis, there was a weak negative correlation between height and flexibility (r=−0.314 p=0.025), height SDS and flexibility (r=−0.254 p=0.092), height SDS, and purpose (r=−0.285 p=0.058). Also, there was a weak negative correlation between REC and weight (r=−0.435 p=0.003), REC and weight SDS (r=−0.461 p=0.002), REC and height (r=−0.269 p=0.077), REC and height SDS (r=−0.322 p=0.033), REC and BMI (r=−0.289 p=0.058), and REC and BMI SDS (r=−0.353 p=0.019). Conclusions The resilience of girls with CPP treated with GnRHa was found to be similar to their healthy peers. The early diagnosis of the disease and adequate treatment may decrease the discrepancy of somatic changes between girls with CPP and their peers, which may help them to overcome the stress of CPP and long-term 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.

Objective: The aim of this study is to determine the cutoff values of gonadotropin response to gonadotropin-releasing hormone analogs (GnRHas) corresponding to the activation of the hypothalamic–pituitary–gonadal axis that could differentiate central precocious puberty (CPP) from premature thelarche (PT) and using the electrochemiluminescence assay method. Methods: A total of 49 girls underwent the stimulation test with the intramuscular injection of 3.75 mg leuprolide acetate. Based on the clinical and laboratory characteristics, they were divided into two groups: CPP (n = 22) and PT (n = 27). Baseline estradiol, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were collected before GnRHa administration, and LH and FSH at 60 and 120 min, respectively, after GnRHa administration. Results: The girls with CPP presented an increased height Z-score, advanced bone age, and higher baseline LH, FSH, estradiol, and LH/FSH ratio in relation to PT (p < 0.001). Stimulated LH differed significantly between the two groups, and the LH cutoff values were ≥4.29 IU/L (p < 0.001) and ≥3.95 IU/L at 60 and 120 min, respectively (p < 0.001). LH peak was found at 60 min after stimulation. Conclusions: The GnRHa test is effective in distinguishing CPP from PT, and a single sampling, at 60 min, with LH concentrations above 4.29 may be the parameter of choice with the advantage of greater convenience and practicality.
