A 4-Month-Old With Jaundice, Lethargy, and Emesis

Area of Science:

• Pediatric Gastroenterology
• Neonatal Medicine
• Infectious Diseases

Background:

• Acute liver failure (ALF) is uncommon in neonates and infants, posing significant clinical challenges.
• Early identification of etiology and prompt management are crucial for improving outcomes in pediatric ALF.
• Herpes simplex virus (HSV) infection is a known cause of neonatal liver disease.

Purpose of the Study:

• To present a diagnostic dilemma and clinical course of a 4-month-old infant with new-onset ALF.
• To review the differential diagnosis and management strategies for pediatric ALF.
• To discuss the implications of a specific diagnosis in a previously healthy infant with a history of neonatal HSV.

Main Methods:

• Case report presentation of a 4-month-old infant with rapidly progressing liver failure.
• Review of the patient's history, including neonatal mucocutaneous herpes simplex virus disease.
• Discussion of differential diagnoses and clinical evolution from primary and consultative team perspectives.

Main Results:

• The infant presented with new-onset, rapidly progressing liver failure.
• A history of neonatal mucocutaneous herpes simplex virus disease was noted, despite an interval of apparent health.
• The case illustrates the complexities in diagnosing ALF in infants with prior significant medical history.

Conclusions:

• Timely diagnosis and management are critical for infants with acute liver failure.
• Recrudescent or late-onset complications of neonatal infections should be considered in the differential diagnosis of pediatric ALF.
• This case underscores the importance of a multidisciplinary approach in managing complex pediatric liver disease.
