Abstract:
OBJECTIVETo investigate the etiology, pathology, and clinical characteristics of cryptogenic liver diseases in order to develop a pathogenic profile for clinical diagnosis and therapeutic design.
METHODSThe data of the 566 patients diagnosed with abnormal liver function and who had undergone liver biopsy at our institute between January 2006 to March 2010 were retrospectively analyzed. The Chi-squared (x²) test was used to assess disease correlation with sex and the rank sum test was used to assess disease correlation with continuous data since all data had asymmetric distribution.
RESULTSAmong the 566 patients, abnormal liver function was attributed to alcoholic liver disease (n=175; 30.92%), drug-induced or environmentally-induced liver disease (n=101; 17.84%), hereditary and metabolic disease (n=93; 16.43%), infectious hepatitis disease (n=84; 14.84%), fatty liver disease (n=53; 9.36%), and autoimmune liver disease (n=30; 53.00%). Thirty patients had unknown etiology, despite liver biopsy analysis. Among these disease subgroups, there were distinct correlations with sex, age, and levels of alanine transaminase (ALT) and gamma-glutamyltransferase (GGT). The autoimmune liver disease group was correlated with sex (q=9.14, 7.435, 5.071, 9.529, and 12.5, respectively; P less than or equal to 0.01). The alcoholic liver disease group and autoimmune liver disease group were correlated with age (vs. genetic metabolic disease group: q=17.254 and 10.302; infectious hepatitis group: q=17.523 and 10.697); drug/environmentally-induced liver damage group: q=9.170 and 5.266); fatty liver group: q=7.118 and 4.661) (P less than or equal to 0.01). In addition, the alcoholic and autoimmune liver disease groups were correlated with GGT levels (vs. genetic metabolic disease group: q=8.003; infectious hepatitis group: q=4.793; drug/environmentally-induced liver damage group: q=4.404) (P less than or equal to 0.01).
CONCLUSIONLiver pathology is important for the diagnosis of cryptogenic liver diseases. Patient age, sex, and biochemistry index may facilitate diagnosis and treatment in the absence of pathology.
