[CONGENITAL ADRENAL HYPERPASIA].

Area of Science:

• Pediatric Endocrinology
• Genetics
• Neonatal Screening

Context:

• Congenital adrenal hyperplasia (CAH) encompasses a group of genetic disorders affecting the adrenal glands.
• These conditions present diverse clinical and physiopathological characteristics in pediatric patients.
• Early identification and management are critical for improving long-term health outcomes.

Purpose:

• To review the clinical and physiopathological aspects of major CAH types in children.
• To highlight the benefits of newborn screening for CAH using 17-hydroxyprogesterone (17-OHP) levels.
• To emphasize the importance of prenatal diagnosis and management for at-risk pregnancies.

Summary:

• This review details the key clinical manifestations and underlying pathophysiology of prevalent CAH forms in pediatric populations.
• It underscores the significant advantages of universal newborn screening via analysis of 17-OHP on filter paper blood samples.
• The critical role of proactive treatment for high-risk pregnancies prior to delivery is also emphasized.

Impact:

• Facilitates earlier diagnosis and intervention for congenital adrenal hyperplasia in newborns.
• Enables timely management, potentially preventing severe health complications associated with CAH.
• Supports informed clinical decision-making regarding prenatal care and neonatal screening strategies.
