Severe burns cause significant liver enlargement and impaired protein synthesis in children, persisting for up to 12 months. Early interventions may reduce complications associated with liver hypertrophy and failure.

Area of Science:

  • Burn injury research
  • Hepatology
  • Clinical medicine

Background:

  • Hepatic homeostasis and metabolism are critical for survival in critically ill patients, especially after severe burns.
  • Liver hypertrophy (enlargement) is known to occur after burns, but its extent and duration remain unclear.
  • Understanding liver changes post-burn is crucial for managing patient recovery and preventing complications.

Purpose of the Study:

  • To investigate changes in liver size, weight, and protein synthesis in pediatric burn patients.
  • To determine the duration of liver enlargement and functional impairment following severe burns.
  • To establish a baseline for developing targeted therapeutic strategies.

Main Methods:

  • A prospective clinical trial involving 102 pediatric burn patients.

  • Weekly ultrasound measurements of liver size and calculated liver weight throughout hospitalization and up to 12 months post-burn.
  • Assessment of hepatic protein and enzyme levels using standard laboratory techniques.

    • Main Results:

    • Liver size and weight significantly increased during the first week post-burn, peaking at 2 weeks (126% increase).
    • Liver weight remained elevated by 40-50% at 6, 9, and 12 months post-burn.
    • Hepatic protein synthesis was impaired for up to 9 months after the burn injury.

    Conclusions:

    • Severe burn injuries induce significant, prolonged liver enlargement and impaired hepatic protein synthesis in children.
    • These findings highlight the need for interventions to manage liver hypertrophy and dysfunction post-burn.
    • Preventing liver enlargement and improving impaired function could reduce associated complications like liver failure.
