A 71-year-old male who had suffered from multiple sclerosis since 1992 experienced acute exacerbation of autoimmune hepatitis coincident with glatiramer therapy. He was treated with interferon beta-1b between 1994 and 2004. In January 2004, the interferon treatment was interrupted because of elevated serum liver enzyme activities. Two months later, glatiramer acetate 20 mg once a day was initiated. In May 2004, he presented with malaise and jaundice which was associated with elevated serum liver enzyme activities. In November 2005, the patient re-presented with fever, uncharacteristic abdominal symptoms, and elevated serum liver enzyme activities. At this stage, he was diagnosed with autoimmune hepatitis. As therapy, the patient commenced on budesonide 3 mg three times a day. The treatment led to a significant improvement of liver function tests. He was subsequently put on mycophenolate mofetil.
Hepatic side effects have been reported rarely. At least one case of hepatitis has been reported, in addition to a case of acute exacerbation of autoimmune hepatitis.
