Aspirin-induced hepatic dysfunction in a patient with adult rheumatoid arthritis
A patient with classical rheumatoid arthritis receiving high doses of aspirin developed significant elevation of serum glutamic oxaloacetic transaminase. This patient had recently been on phenylbutazone and an initial liver biopsy, at the time of elevation of the transaminase revealed nonspecific mild fatty infiltration of the liver compatible with the pathology seen with rheumatoid disease. Because of the severity and activity of her rheumatoid arthritis, and thus the need to know whether aspirin was the etiologic factor in liver dysfunction, the patient was challenged with aspirin. SGOT elevation occurred after a 4–6-day lag period, which promptly remitted when salicylates were discontinued. A liver biopsy at this time revealed evidence for degeneration, regeneration, and mild focal mononuclear infiltration. Although previous reports note salicylate-related hepatocellular dysfunction in patients with systemic lupus erythematosus and juvenile rheumatoid arthritis, these data clearly demonstrate the relationship of ASA to liver dysfunction in a patient with adult onset rheumatoid arthritis. The histologic picture as well as the clinical course of this patient's hepatic abnormality suggest a toxic rather than hypersensitivity etiology for this syndrome.
