PURPOSE: It was aimed to compare circulating levels of ghrelin, leptin, peptide YY (PYY), and neuropeptide (NPY) between girls with idiopathic central precocious puberty (ICPP) and prepubertal girls, as well as to evaluate alterations in these hormone levels and body composition during leuprolide acetate treatment in girls with ICPP.
METHODS: This prospective study was conducted on girls with isolated premature thelarche (IPT), girls with ICPP, and age-matched prepubertal controls. Anthropometric measurements, body composition analysis and appetite-regulating hormone level measurements were performed in each group and also at the 6th and 12th months of the leuprolide acetate treatment for the girls with ICPP.
RESULTS: Seventy-three girls participated in the study (24 girls with ICPP, 28 with IPT, and 21 prepubertal controls). No significant differences were observed in ghrelin, leptin, PYY, and NPY levels among the three groups. Leuprolide acetate treatment resulted in increased leptin, decreased PYY and NPY levels, and no significant changes in ghrelin. Despite no significant change in body mass index standard deviation score (BMI SDS), body fat percentage increased during treatment.
CONCLUSION: While appetite-regulating hormones do not seem to directly contribute to precocious puberty pathogenesis, puberty blockade was shown to lead to altered levels of these hormones along with changes in body composition.
