Liver dysfunction and acute cardiocirculatory failure in children.

Area of Science:

• Pediatric Gastroenterology
• Hepatology
• Critical Care Medicine

Background:

• Acute circulatory failure in children can lead to organ-specific complications.
• Transient liver dysfunction is a recognized, though less common, consequence of severe illness in pediatric patients.

Purpose of the Study:

• To investigate the incidence and characteristics of transient liver dysfunction in children following cardiocirculatory failure.
• To establish diagnostic criteria for ischemic liver injury in pediatric patients.

Main Methods:

• Retrospective case series of 15 children with cardiocirculatory failure and subsequent liver injury.
• Analysis of clinical data, including onset of liver injury, serum transaminase levels (SGOT, SGPT), prothrombin time (PT), and glucose levels.
• Correlation of liver dysfunction parameters with the resolution of circulatory failure.

Main Results:

• All 15 children presented with cardiocirculatory failure preceding liver injury.
• Elevated transaminases (SGOT, SGPT) peaked between days 1-3 and normalized by days 6-10.
• Prothrombin time was significantly reduced in 13/15 patients, normalizing by day 10.
• Hypoglycemia was observed in 8/15 patients on day 1.
• Liver function improved following correction of the underlying circulatory compromise.

Conclusions:

• Transient hepatic dysfunction is a frequent complication of acute circulatory failure in children, likely due to hepatic hypoperfusion.
• Diagnosis of pediatric ischemic liver injury or shock liver syndrome can be established using clinical and biochemical findings.
• Liver biopsy is not necessary for diagnosing this condition in children.
