    ABSTRACT: Estrogens, growth hormones and IGFs are essential in the development and growth of the skeleton and for the maintenance of bone mass and density. Treatment of precocious puberty with gonadotropin-releasing hormone analogs (GnRHa), leads to a situation of hypoestrogenism by reducing sex-steroid levels, which, theoretically, may have a detrimental effect on bone mass during pubertal development. A reduction in bone mineral density during GnRHa treatment has been shown, but GnRHa treatment in patients with central precocious puberty does not seem to impair the achievement of normal peak bone mass at adult height. However, calcium supplementation is effective in improving bone densitometric levels and may promote better peak bone mass achievement.

    ABSTRACT: To assess the prevalence of polycystic ovary syndrome (PCOS) in a cohort of young women with previous idiopathic central precocious puberty (ICPP) at least 3 years after menarche, and to look for any predictive factors of PCOS at the time ICPP was diagnosed. Longitudinal study. Pediatrics unit, Verona, Italy. Forty-six young women (18.1 +/- 3.0 years) who had been treated with GnRH analogues during childhood, observed at gynecologic age of 6.23 +/- 3.3 years. Semistructured interview concerning cycles, physical exam, blood sampling, and transabdominal pelvic ultrasound. Oligomenorrhea, LH, FSH, E(2), T, DHEAS, free T, delta4-androstenedione, 17-OHP, P, polycystic ovary morphology (PCOM). Fifteen percent of the young women had oligomenorrhea, 28% clinical hyperandrogenism, 48% biochemical hyperandrogenism, and 37% PCOM. A total of 32% of the patients had PCOS according to the Rotterdam definition and 30% had PCOS according to the Androgen Exess Society. The prevalent phenotype of PCOS was characterized by clinical and/or biochemical hyperandrogenism and PCOM. We did not find any predictive factors for PCOS at the time ICPP was diagnosed. Patients with ICCP are prone to developing PCOS. The prominent phenotype in this cohort was PCOM associated with clinical and/or biochemical hyperandrogenism. Further follow-ups of these young adult patients will clarify whether this phenotype persists and if it will have important long-term implications regarding increased risk of infertility or metabolic complications.
