Abstract
Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease that can lead to cirrhosis in up to 30% of patients. Cirrhotic patients are at risk of high morbidity and mortality due to cirrhosis decompensation and hepatocellular carcinoma (HCC). This retrospective study assessed the rates of decompensated cirrhosis and HCC in patients with AIH-related cirrhosis. A total of 774 AIH patients were included, with 40% developing cirrhosis. Over a median follow-up of 8.2 years (IQR 2.9-12.3), the annual incidence of decompensated cirrhosis was 4.25%, with a mean time of 8.2 years from cirrhosis diagnosis to decompensation. Nineteen cirrhotic patients (6.2%) developed HCC, with a yearly incidence rate of 0.63%. Most HCC cases occurred within the first years of cirrhosis diagnosis. The rate of decompensated cirrhosis in AIH patients was lower than in other cirrhotic liver diseases, suggesting AIH may follow a different clinical course. The annual incidence of HCC was also significantly lower than the threshold for HCC surveillance. This indicates the need to reassess current surveillance guidelines, particularly in the late years following a cirrhosis diagnosis.
