PURPOSE: To analyse anatomoclinic and evolutive aspects of autoimmune hepatitis (AIH) through 50 observations collected in two Internal Medicine departments in Algiers from 1998 to 2002 and to make a review of the literature. METHODS: The study is prospective. The diagnosis of autoimmune hepatitis (AIH) is established according to the recommendations of the score of the International Autoimmune Hepatitis Group (1991) or/and hepatitic damage confirmed by histology. RESULTS: Fifty patients were studied: (32 women-18 men) and the mean age was 38 years (17 to 73). Autoimmune extra-hepatitic manifestations were associated in 26%. The AIH type 1 has been noted in 58%. AIH were type 2 in only 6%. In 22% of the cases AIH were sero-negative and the others AIH represented 14% were classed as overlap-syndrome (5 cases of primary biliary cirrhosis and 2 cases of primary sclerosing cholangitis hepatitis overlap syndrome). The first liver biopsy tissue showed strong necrotic-inflammatory activity in 56% and cirrhosis was identified in 19 patients (38%). The treatment (azathioprine and corticosteroid) was prescribed in 37 patients (74%) in active chronic hepatitis or in compensed cirrhosis. FOLLOW-UP: 28% of the patients died (9-36 months) because cirrhosis's complications or because complications of hepatocarcinoma (3 cases). CONCLUSION: The diagnosis of AIH must be established early for each patient with chronic liver disease particularly is those are supposed as a crypto genetic hepatitis. The prognosis is compromised by delayed diagnosis and the mortality in middle following up is high.
