Abstract:
Objective To evaluate the clinical and histological features of patients with abnormal liver tests of unknown etiology, and then to investigate the diagnosis and differential diagnosis. Methods Patients with abnormal liver function test hospitalized and had liver biopsies during 2008-2009 constituted this retrospective study cohort. After excluding those patients diagnosed with hepatotropic viral hepatitis,space occupying lesions of the liver, alcoholic liver disease and obstruction of bile duct caused by stone or malignancy and AMA/AMA-M2 positive of primary biliary cirrhosis ( PBC ), the clinical and histological characteristics were evaluated. Results Out of the 180 patients who underwent liver biopsy, 88 patients were included in the present analysis. The final diagnosis involved 15 categories of diseases, with druginduced liver injury ( DILI ) [34. 09% ( 30/88 )], autoimmune liver diseases [22.73% ( 20/88 )], and nonalcoholic fatty liver disease (NAFLD) [12. 50% ( 11/88 )] being the most common causes, following by genetic and other rare diseases. Conclusion DILI, autoimmune liver disease and NAFLD were the most common causes of abnormal liver tests in these non-viral liver diseases. Some rare diseases such as hereditary metalbolic liver disease also represent a considerable proportion in patients with abnormal liver function test.
