Outcome of acetaminophen overdose in pediatric patients and factors contributing to hepatotoxicity

Area of Science:

• Pediatric Toxicology
• Hepatology
• Clinical Pediatrics

Background:

• Acetaminophen (paracetamol) is a common over-the-counter medication.
• Overdose can lead to severe hepatotoxicity, especially in pediatric populations.
• Understanding risk factors is crucial for prevention and timely intervention.

Purpose of the Study:

• To review medical records of pediatric patients admitted for acetaminophen overdose.
• To identify the incidence of severe liver toxic effects and the need for liver transplantation.
• To determine the primary causes and risk factors for acetaminophen overdose in young children.

Main Methods:

• Retrospective review of 73 pediatric patient medical records.
• Analysis of patient demographics, overdose circumstances, and clinical outcomes.
• Assessment of liver toxic effects and treatment interventions, including liver transplantation.

Main Results:

• Twenty-eight out of 73 pediatric patients (39%) experienced severe liver toxic effects.
• Six patients required liver transplantation due to acetaminophen-induced liver failure.
• Parental miscalculation of dosage and delayed initiation of antidote therapy were identified as major risk factors.

Conclusions:

• Acetaminophen overdose is a significant cause of severe liver injury in children.
• Younger children (≤10 years) are particularly vulnerable due to dosing errors.
• Prompt recognition and management of acetaminophen overdose are critical to prevent severe outcomes.
