Abstract
Background: Hepatocellular cholestasis denotes the alteration of bile secretion by hepatocytes. The causes, degree of hepatocyte injury and concomitant bile duct loss are considered to influence the clinical course.
Methods: The causes and pathological features of hepatocellular cholestasis were analyzed in 62 cases of liver biopsies; and the causes of primary biliary cirrhosis, primary sclerosing cholangitis, and biliary obstruction were not included.
Results: The mean age of the patients was 42.2 years, and the ratio of male to female was 1.8:1. Fiftyeight cases (94%) showed cholestatic hepatitis, and 4 cases (6%) showed pure cholestasis without hepatitis activity. The majority of the cases (52 cases, 84%), including 19 cases of herbal medicine, was related to drugs. Loss of bile duct was found in 12 cases (19%), which were all cases of chronic cholestasis. All of them had drug histories, including 9 cases of herbal medicine. Clinical follow-up was performed in 9 out of the 12 cases with bile duct loss, and all of them showed elevated total bilirubin and/or alkaline phosphatase levels for more than 6 months.
Conclusions: Drugs are the major cause of hepatocellular cholestatic hepatitis/cholestasis; and information about drugs, including herbal medicines, should be considered for proper evaluation of liver biopsy with hepatocellular cholestasis. Bile duct loss should be evaluated in the cases of chronic hepatocellular cholestasis, especially in drug induced cases.
