Hépatite lupique : une série de 12 patients

Abstract

Purpose Several liver manifestations have been reported in systemic lupus erythematosus (SLE) and are usually non specific. We report on our experience of lupus hepatitis. Methods A retrospective monocenter study of 73 patients with SLE. The diagnosis of lupus hepatitis was established after exclusion of other causes of hepatitis and hepatic vein thrombosis. Results Liver involvement was noted in 12 patients (16.4%). There were nine female and three male patients; the mean age of these patients was 29 years. In seven patients liver involvement was concurrent with the diagnosis of SLE and it occurred later during an exacerbation of the disease in the five remaining patients. In all patients, liver manifestations were associated with other organ involvement. Clinical manifestations were: hepatomegaly ( n = 4), jaundice ( n = 4), abdominal pain ( n = 3), ascitis ( n = 2), portal hypertension ( n = 1) and hepatic failure with encephalopathy ( n = 1). Elevated liver enzyme was noted in 11 cases and liver cholestasis in eight cases. Presence of anti-ribosomal P antibodies was noted in one case. Liver biopsy was performed in five patients, and revealed chronic active hepatitis in three cases, chronic hepatic granulomas in one case and nonspecific inflammation in one case. The outcome was favorable in 11 patients without relapse, and one patient died of encephalopathy and liver failure. Conclusion Liver involvement associated with SLE is not uncommon. It is frequently asymptomatic and limited to liver test abnormalities. The role of anti-ribosomal P autoantibodies remains uncertain.
