[Two cases of rheumatoid arthritis presenting autoimmune hepatic diseases].
We report on two cases of rheumatoid arthritis (RA) presenting autoimmune hepatic diseases. The first patient, who had been diagnosed as RA at the age of 63, was hospitalized in order to undergo surgery for total left knee replacement at the age of 69. She acquired acute serum hepatitis as a result of blood transfusion she received during the operation. Five years later, she visited our clinic suffering from polyarthritis. She was found to have hyper-alkaline phosphatase (ALP) and hyper rGTP, but no AMA. The second patient, a 60-year-old female whose onset of RA was at the age of 45, complained of general fatigue, and was admitted to the hospital because of persistent liver dysfunction. When corticosteroid was administered to these patients, ALP and rGTP levels in the first case, and AST and ALT levels in the second case were reduced to values in the normal range. ANA in the first case continued to register negative, but ANA in the second case became positive after the patient developed acute hepatitis. Both patients were found to have anti-p25 triplet liver/kidney microsome antibody. We discuss the clinical significance of this antibody.
