Hepatic failure in a child with anti-epileptic hypersensitivity syndrome

Area of Science:

• Pediatric Medicine
• Pharmacology
• Hepatology

Background:

• Phenobarbitone is an anticonvulsant medication with known risks of hypersensitivity reactions.
• Severe hypersensitivity reactions can manifest with multi-organ involvement.
• Fulminant hepatic failure is a rare but life-threatening complication of drug reactions.

Observation:

• An 11-year-old boy presented with severe hypersensitivity to phenobarbitone, progressing to fulminant hepatic failure.
• The patient subsequently developed symptoms consistent with severe acute respiratory syndrome (SARS).
• The SARS-like illness potentially complicated the management and recovery from the initial hypersensitivity reaction.

Findings:

• The hypersensitivity reaction to phenobarbitone was the primary cause of the severe illness.
• The co-occurrence of SARS-like symptoms presented a diagnostic and therapeutic challenge.
• Intravenous immune globulin and corticosteroids were effective in controlling the hypersensitivity reaction.

Implications:

• This case highlights the potential for severe, multi-systemic reactions to phenobarbitone in children.
• The interplay between drug hypersensitivity and infectious/syndromic illnesses requires careful consideration in clinical practice.
• Prompt and aggressive immunosuppressive therapy can be crucial for managing severe hypersensitivity reactions.
