A newborn with combined pituitary hormone deficiency developing shock and sludge

Area of Science:

• Neonatal Endocrinology
• Pediatric Cardiology
• Hepatology

Background:

• Severe combined pituitary hormone deficiency (CPHD) is a rare condition affecting multiple pituitary hormones.
• Neonatal presentation of CPHD can be subtle, leading to delayed diagnosis.
• Central adrenal insufficiency is a critical component of CPHD with significant implications.

Observation:

• A male neonate presented with respiratory distress and shock refractory to catecholamines shortly after birth.
• Clinical signs including hypoglycemia and micropenis suggested CPHD.
• Brain MRI revealed anterior pituitary aplasia and ectopic posterior pituitary gland.

Findings:

• Hydrocortisone (HDC) administration rapidly improved the neonate's circulatory dynamics, indicating central adrenal insufficiency.
• Elevated liver enzymes (γ-GTP) and direct bilirubin, along with ultrasound findings of sludge, suggested cholestasis.
• Treatment with ursodeoxycholic acid and recombinant human growth hormone (rhGH) resolved the cholestasis and sludge.

Implications:

• Severe CPHD, particularly central adrenal insufficiency, can precipitate cardiogenic shock in neonates.
• Early diagnosis of CPHD is vital for timely intervention and preventing life-threatening complications.
• Multisystemic involvement in CPHD necessitates comprehensive management strategies, including hormonal replacement and supportive care.
