Abstract
Autoimmune hepatitis (AIH) is a form of chronic hepatitis of unknown etiology. It was first described in the 1950s as a form of chronic hepatitis noted in younger women. It was later termed lupoid hepatitis due to its association with autoantibodies before being named AIH in 1965. Corticosteroids and azathioprine have been the standard therapy for AIH, but due to treatment failures and toxicities from these medications, new medications are being investigated as possible treatment options. Rituximab has been used in various autoimmune disorders with good success. We report the case of a 34-year-old Caucasian woman with a history of B cell lymphoma and concurrent AIH treated with rituximab. The diagnosis of AIH was made by classic serological and histological features. The patient was initially treated with steroids but had a progression of her disease as well as suffering toxicities from the steroids. She was then given eight weeks of rituximab with good improvement in both laboratory and histological findings.
