Update on central precocious puberty: from etiologies to outcomes

Introduction: Precocious puberty (PP) is one of the most common reasons for referral to pediatric endocrinologists. Gonadotropin-releasing hormone analogs (GnRHas) are the gold standard for the treatment of central precocious puberty (CPP) and have an impressive record of safety and efficacy. However, ongoing refinements in diagnosis and management continue to lead to important advancements in clinical care. Areas covered: The aim of this review is to cover current considerations and controversies regarding the diagnosis of CPP, as well as new findings in regards to etiology and treatment modalities. Expert opinion: There is emerging evidence of monogenic etiologies of CPP and significant progress in the expansion of newer formulations of GnRHas. Despite these exciting developments, areas of uncertainty in the diagnosis and treatment of CPP remain. While long-term outcomes of patients treated for CPP are encouraging, only short-term follow-up is available with respect to the newer extended release GnRHa preparations, and how they compare with historically used formulations is unknown. A particular shortage of information exists pertaining to CPP in boys and regarding the psychological implications of PP in girls, and more research is needed. Continued investigation will yield new insights into the underlying genetics and optimal treatment strategies for CPP
