What is Central Precocious Puberty?

Central precocious puberty (CPP) is a condition that causes early sexual development in children, typically before the age of 8 in girls and 9 in boys. This means that puberty starts too soon, but develops as usual.

• In most cases, there's no medical problem or other known reason for the early puberty.
• However, rare cases can be caused by a tumor in the brain or spinal cord [1].
• CPP is more common in girls than boys, and most cases are idiopathic (without a clear cause) [2].

Signs of Central Precocious Puberty

The signs of CPP can vary depending on the child's age and sex. Some common signs include:

• Sudden growth spurt
• Breast bud development in girls
• Enlarging testicles and penis, facial hair, pubic and underarm hair, spontaneous erections and/or ejaculations, development of acne, deepening of the voice [3]
• Body odor and changes in body shape [6]

Treatment for Central Precocious Puberty

The decision to treat CPP depends on the age of the child and the progression of puberty. If the child has rapidly progressing symptoms or if bone age is significantly advanced, treatment may be considered. The main goals of treatment are to preserve adult height and alleviate psychosocial stress [10].

Treatment options for CPP include hormone therapy, which can help regulate growth and development [12]. In some cases, a histrelin implant may be used, which lasts up to a year and involves minor surgery [12].

Signs and Symptoms of Central Precocious Puberty

Central precocious puberty (CPP) is a condition that causes early sexual development in children, typically before the age of 8-9 years old. The signs and symptoms of CPP are similar to those experienced during normal puberty, but occur at an earlier age.

• Rapid Height Growth: Children with CPP may experience a growth spurt, leading to rapid height increases.
• Pubic or Underarm Hair Development: Pubic hair and underarm hair development can be an early sign of CPP in both boys and girls.
• Adult Body Odor: The onset of adult body odor is another common symptom of CPP.
• Acne: Acne can occur due to the hormonal changes associated with puberty.
• Voice Deepening: In boys, a deepening voice is often one of the first signs of puberty, which can also be seen in children with CPP.

These symptoms are usually the same as those experienced during normal puberty, but occur at an earlier age. It's essential for parents and caregivers to recognize these signs and consult a healthcare professional if they suspect their child may be experiencing early puberty.

Treatment Options for Central Precocious Puberty

Central precocious puberty (CPP) is a condition where children experience premature development of body characteristics, typically due to an imbalance in hormone levels. In most cases, the treatment involves medication to delay or halt the progression of puberty.

• Gonadotropin-Releasing Hormone Agonists (GnRHas): These are the gold-standard treatment for CPP worldwide and have a proven track record of safety and efficacy [1][5]. GnRHas work by providing a steady concentration of GnRH activity, which helps to regulate hormone levels in the body. Examples of GnRHas used to treat CPP include leuprolide and histrelin.
• Long-acting analogs: Recent years have seen significant growth in the availability of longer-acting and sustained-release forms of GnRHas [5]. These newer formulations can provide a steady concentration of GnRH activity for an extended period, reducing the need for frequent injections or implants.

Goals of Treatment

The primary goal of treatment for CPP is to preserve height potential and prevent premature closure of growth plates. By delaying or halting puberty, healthcare providers aim to give children more time to grow and develop physically before entering adolescence [13][15].

Treatment Outcomes

Studies have shown that GnRHas are effective in treating CPP, with a high success rate in preserving height potential and preventing premature closure of growth plates [12][14]. However, the effectiveness of treatment may vary depending on individual factors, such as age at diagnosis and duration of treatment.

There is a general consensus among paediatric endocrinologists that the treatment of true CPP (i.e., in children young enough to have a formal diagnosis) is indicated in many cases.

Differential Diagnosis of Central Precocious Puberty

Central precocious puberty (CPP) is a condition where children experience early activation of the hypothalamic-pituitary-gonadal axis, leading to premature development of secondary sex characteristics. To accurately diagnose CPP, it's essential to rule out other conditions that may present with similar symptoms.

Differential Diagnoses:

• Premature Thelarche: This condition is characterized by breast development in girls before the age of 8 years. It's a benign variant of puberty and often resolves on its own without treatment.
• Premature Adrenarche: This condition refers to the early onset of pubic hair growth, body odor, and acne in children. It's usually caused by an increase in adrenal hormones and can be a precursor to CPP.
• Congenital Adrenal Hyperplasia (CAH): This is a rare genetic disorder that affects the production of adrenal hormones, leading to early puberty-like symptoms.
• Central Nervous System Lesions: Certain brain tumors or lesions can cause precocious puberty by stimulating the hypothalamus and pituitary gland.
• Genetic Disorders: Some genetic conditions, such as McCune-Albright syndrome, can lead to CPP.

Key Considerations:

• Age of Onset: Children with CPP typically experience breast development before the age of 8 years in girls or testicular enlargement before the age of 9 years in boys.
• Rapid Progression: CPP is often characterized by rapid progression of puberty symptoms, whereas other conditions may progress more slowly.

Diagnostic Evaluation:

A comprehensive diagnostic evaluation should include a thorough medical history, physical examination, and laboratory tests to rule out other causes of precocious puberty. This may involve:

• LH and FSH Levels: Measuring luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels can help confirm the diagnosis of CPP.
• Imaging Studies: Imaging studies, such as MRI or CT scans, may be necessary to rule out central nervous system lesions.
