Histological characteristics and prognosis in patients with fatty liver

Objective The clinical-pathological spectrum of fatty liver ranges from simple steatosis to end-stage fibrotic liver disease. However, no histological characteristics have been identified that can predict progression from pure steatosis to fibrotic liver disease in non-alcoholic fatty liver disease. The objective of this study was to investigate whether histological characteristics in patients with fatty liver without inflammation could predict mortality or development of cirrhosis. Material and methods A total of 417 patients had a liver biopsy performed, which showed fatty liver without inflammation. The population consisted of 170 non-alcoholic and 247 alcoholic fatty liver patients. The study cohort was linked through their unique personal identification number to The National Registry of Patients and the nationwide Registry of Causes of Death. Results Median follow-up time was 19.9 years in the non-alcoholic group and 12.8 years in the alcoholic group. Overall mortality in the non-alcoholic group was...
