Salicylate hepatitis: a complication of the treatment of Kawasaki's disease.

A case of salicylate hepatitis in a seven-week-old boy with Kawasaki's disease, mucocutaneous lymph node syndrome, is reported. The infant was admitted to the hospital with fever and a diffuse maculopapular petechial rash. He was treated with antibiotics for 72 hours for presumed septicemia. His condition deteriorated and he developed mucous membrane lesions and edema in his hands and feet. When the cultures of spinal fluid, blood, and urine were found to be negative, the antimicrobial therapy was discontinued; however, the cyanosis of his extremities progressed and gangrenous regions developed in his toe and finger pads. Oral aspirin therapy was started at a dosage of 100 mg/kg/day, every six hours. After five days, the rash, membrane lesions, and swelling in his hands and feet resolved. The cyanosis regressed. Liver enzyme tests revealed mild elevations of SGOT and LDH, and on the 12th hospital day these values peaked to a level consistent with salicylate hepatitis. The aspirin therapy was discontinued and within four days the liver function test results were normal. Aspirin therapy was reinstituted at a single daily dose of 30 mg/kg with no recurrence of hepatitis. The careful monitoring of liver function tests is recommended for children with Kawasaki's disease receiving aspirin therapy to avoid salicylate-induced hepatitis.
