The liver histology of 52 patients treated with intermittent low dose pulse methotrexate for rheumatoid arthritis was evaluated using a modification of the Roenigk grading system. Patients studied had had an average of 3.2 years of treatment or had received 1.7 g methotrexate. No patient had cirrhosis; 15 (29%) patients had evidence of mild fibrosis. Histological abnormalities were not predicted by liver function test changes, with the exception that hypoalbuminaemia occurred in 60% of those with grade IV (modified criteria) findings. The need for liver biopsy in patients with rheumatoid arthritis treated with methotrexate before two years or 1500 mg of treatment has not been established. Whether serial liver biopsies will be needed beyond this time has yet to be determined.
