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.

Monitoring Treatment

AbstractThe objective of this study was to validate basal, post-gonadotropin-releasing hormone analogue (post-GnRHa) and first-voided urinary LH (ULH) as alternatives to an LHRH stimulation test in monitoring treatment efficacy in central precocious puberty (CPP).Seventeen girls with CPP were followed over 22.5±9.1 months during GnRHa (triptorelin) treatment. ULH and post-GnRHa LH levels were obtained every 4 months before and 24 h after GnRHa administration, respectively, along with clinical and bone age (BA) evaluation. LHRH stimulation tests were performed annually.A total of 36 LHRH stimulation tests demonstrated adequate suppression with a peak LH of 0.57±0.33 IU/L. The corresponding basal LH was 0.27±0.16 IU/L. Ninety post-GnRHa LH measurements were similar to LHRH-stimulated LH levels (0.56±0.31 IU/L), whereas 8% of ULH levels were above prepubertal threshold. Fourteen episodes of growth acceleration and ten episodes of BA advancement resolved without treatment modification.Suppressed basal and post-GnRHa LH levels indicate adequate suppression of puberty. Clinical breakthroughs during treatment are transient and resolved spontaneously.
