Acute sulphasalazine hepatotoxicity

Area of Science:

• Hepatology
• Clinical Pharmacology
• Immunology

Background:

• Sulfasalazine is a widely used medication for inflammatory bowel disease and rheumatoid arthritis.
• Hepatotoxicity is a rare but serious adverse effect associated with sulfasalazine therapy.
• Hypersensitivity reactions can manifest with diverse clinical presentations, including hepatic injury.

Observation:

• A case of severe hepatotoxicity attributed to sulfasalazine is presented.
• The patient exhibited clinical and biochemical features consistent with an acute hypersensitivity reaction.
• Corticosteroids were intentionally withheld during the management of this case.

Findings:

• The patient's liver function normalized solely after the discontinuation of sulfasalazine.
• The absence of steroid administration did not impede recovery, suggesting a hypersensitivity-mediated mechanism.
• Supportive treatment was sufficient for managing the drug-induced liver injury.

Implications:

• This case highlights the importance of recognizing sulfasalazine-induced hepatotoxicity as a hypersensitivity phenomenon.
• It suggests that supportive care and drug withdrawal may be adequate, potentially avoiding the need for corticosteroids.
• Clinicians should consider sulfasalazine hepatotoxicity in patients presenting with acute liver injury, especially those on the medication.
