Peripheral Precocious Puberty Due to Autonomous Gonadal Activation: A Multicenter Experience
Abstract
Introduction: Peripheral precocious puberty (PP) is far less commonly encountered compared to central precocious puberty (CPP) in pediatric endocrine practice. Long-standing non-diagnosis may cause rapidly advancing bone age, leading to CPP and resultant short stature. We aimed to report the clinical profile and current Indian experience in the management of children with peripheral PP due to autonomous gonadal activation.
Methods: This multicentric retrospective study reports data on 23 children (20 girls) presenting with peripheral PP as a result of autonomous gonadal activation from eight pediatric endocrine centers across India. Their clinicodemographic, anthropometric, and laboratory measurements were reviewed.
Results: The mean ± SD chronological age at the time of presentation was 4.9 ± 2.0 years, and the mean bone age was 7.6 ± 2.6 years. Nine (39%) children were tall for mid-parental height. Thirteen (57%) children were diagnosed with McCune Albright syndrome (MAS), one boy (4%) with familial male-limited PP, and nine (39%) with functional ovarian cysts. Ninety-five percent of girls had menarche as their presenting complaint, with mean age at menarche being 4.6 ± 2.3 years. Ovarian cysts were present in 16 girls, of whom seven (43.8%) had MAS. PP in seven (30%) children progressed to CPP, with mean age of CPP being 6.6 ± 2.1 years. Letrozole was the primary drug of choice, while leuprolide acetate was added in children who progressed to CPP.
Conclusion: We report…
