We report the case of a 61-year old female with a 20-year history of seropositive rheumatoid arthritis (RA) who developed acute hepatitis. Her arthritis had been treated with methotrexate (MTX) since 2003 and, following an increase in disease activity, Rituximab (RTX) was commenced in January 2017. In May 2020, routine blood tests showed a new elevation in her liver profile, although synthetic function was preserved. A standard liver screen found no cause for her acutely abnormal lab values. Upon additional serological testing, the patient was confirmed to have acute hepatitis E virus (HEV). Her primary complaint at the time was fatigue. Within a month, her liver blood tests spontaneously improved and her symptoms resolved with conservative management.
