摘要Background: Patients with non-alcoholic steatohepatitis (NASH) have increased mortality and liver-related complications. In contrast, simple steatosis is considered benign and non-progressive. Objective: To investigate disease progression in patients with different degrees of non-alcoholic fatty liver disease (NAFLD) activity. Design: Prospective longitudinal hospital-based cohort study. Patients: Fifty-two patients (age 44±9 years) with biopsyproven NAFLD had liver biopsies repeated at month 36. Results: Among 13 patients with simple steatosis at baseline, 2 (15%) had a normal liver at month 36, 3 (23%) continued to have simple steatosis, 5 (39%) developed borderline NASH and 3 (23%) developed NASH. Among 22 patients with borderline NASH at baseline, 4 (18%) had simple steatosis and 13 (59%) had borderline NASH at month 36, while 5 (23%) developed NASH. Among 17 patients with NASH at baseline, 10 (59%) continued to have NASH and 6 (35%) had borderline NASH at month 36. Only 1 (6%) patient regressed to simple steatosis. Overall, 14 (27%) patients had fibrosis progression, 25 (48%) had static disease, and 13 (25%) had fibrosis regression. Reduction in body mass index and waist circumference was independently associated with non-progressive disease activity and fibrosis. The baseline serum levels and month 36 changes in adiponectin, tumour necrosis factor α, interleukin 6 and leptin were not associated with disease progression. Serum cytokeratin-18 fragment level reflected disease activity and its change correlated with the change in NAFLD activity score (R=0.51, p<0.001). Conclusions: Patients with simple steatosis may still develop NASH and fibrosis progression. Weight reduction is associated with non-progressive disease. All patients with NAFLD should undergo periodic assessment and lifestyle modification.
