Case report: Pediatric hepatopulmonary syndrome despite strict weight control after craniopharyngioma surgery

Area of Science:

• Pediatric Endocrinology
• Neuro-oncology
• Metabolic Disorders

Background:

• Childhood-onset craniopharyngiomas can lead to hypothalamic obesity and panhypopituitarism, increasing risks of diabetes and fatty liver disease.
• Growth hormone (GH) deficiency is a common complication, impacting metabolism and potentially liver health.
• Weight management is crucial but often insufficient due to hypothalamic dysfunction.

Observation:

• A case study of a patient with normal growth despite GH deficiency, who did not receive GH replacement therapy.
• The patient experienced persistent hypothalamic obesity and developed hepatopulmonary syndrome despite efforts at weight control.
• This highlights limitations of weight management alone in preventing severe liver complications.

Findings:

• GH deficiency can contribute to nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH) progression, irrespective of growth rate.
• Even with successful weight control, liver complications like hepatopulmonary syndrome can occur.
• GH replacement therapy may offer benefits beyond growth promotion, particularly for liver health.

Implications:

• GH replacement therapy should be considered for children with GH deficiency and hypothalamic obesity, even if growth is normal.
• This approach may be vital in preventing severe liver disease, including cirrhosis.
• Rethinking treatment paradigms for pediatric craniopharyngioma survivors is necessary to address metabolic and hepatic sequelae.
