[Fatty liver assessed by histologic examination in patients with hyperlipoproteinemia].

Out of 665 patients after liver biopsy performed during 14 years of the work of the Clinic, 35 cases of patients with non-alcoholic liver steatosis and hyperlipoproteinaemia were selected and analysed retrospectively. The cases of patients with the presence of HBV or HCV infection markers were excluded. The histological material was divided according to the intensity of steatosis expressed as the per cent of hepatocytes with the features of fatty degeneration and also according to the following classification: I--steatosis, II--steatosis with hepatitis, III--steatosis with portal fibrosis, IV--steatotic cirrhosis. In the patients in whom the per cent of hepatocytes with fatty degeneration in biopsy examination exceeded 60%, the mean serum triglyceride concentration was 5.53 mmol/l and was over twice higher than that in the group with steatosis not exceeding 30% of hepatocytes. Similarly, in the patients with steatosis and accompanying hepatitis (steatohepatitis), the mean triglyceride concentration was 5.28 mmol/l and was over twice higher than that in the patients with steatosis with accompanying portal fibrosis. The patients with steatohepatitis had significantly lower HDL concentrations than those with the remaining types of histological changes.
