Approach to the Patient: Central Precocious Puberty

Area of Science:

• Pediatric Endocrinology
• Reproductive Medicine
• Genetics

Background:

• Central precocious puberty (CPP) is defined as early activation of the hypothalamic-pituitary-gonadal axis.
• Sexual development before age 8 in girls and 9 in boys characterizes CPP.
• A secular trend shows earlier thelarche, but pubertal progression and adult height may be unaffected in some girls aged 6-8.

Purpose of the Study:

• To review current diagnostic and management strategies for CPP in girls.
• To highlight advancements in understanding CPP genetics and treatment.
• To address the clinical care challenges due to limited controlled studies and practice guidelines.

Main Methods:

• Review of literature on CPP diagnosis and management.
• Focus on ultrasensitive luteinizing hormone assays and genetic insights.
• Evaluation of gonadotropin-releasing hormone analog (GnRHa) formulations and long-term outcomes.

Main Results:

• Ultrasensitive LH assays reduce the need for stimulation testing.
• Longer-acting GnRHas are available for CPP management.
• Emerging data on GnRHa show reassuring long-term outcomes regarding obesity, cardiovascular risk, and fertility.

Conclusions:

• Despite diagnostic and therapeutic advances, CPP management lacks robust clinical trial data and clear guidelines.
• Focus remains on diagnosis and management of CPP in girls, especially those with thelarche between 6-8 years.
• Further research is needed to support evidence-based clinical decision-making in CPP.
