Chronic hepatitis during rheumatoid arthritis.

Chronic hepatitis is infrequently reported in the course of RA (1.9%). We report 6 cases with such an association. The six patients were all female (mean age: 59.5 years) with typical RA (ACR criteria), and sicca syndrome in 5 cases. Chronic hepatitis always developed after the onset of RA (delay: 1 to 47 years). Laboratory findings revealed a mild increase of transaminases. Alkaline phosphatase were increased in 3 cases. Liver insufficiency was present in 4 cases and polyclonal hypergammaglobulinemia in 6 cases. Rheumatoid factors were detected in 5 cases; antinuclear antibodies and anti-smooth muscle antibodies were also detected in 5 cases. Histological examination of liver biopsy disclosed active chronic hepatitis in 5 cases (with cirrhosis in 3 cases) and persistent chronic hepatitis in 1 case. Steroid therapy was administered in 4 cases of active chronic hepatitis with clinical and biological improvement (18 months to 6 years follow-up). One patient died of gastric bleeding.
