Abstract:
Objective To analyze the clinical and histological features of drug-induced autoimmune hepatitis (DI-AIH).Methods From January 2008 to June 2011,five patients with auto-immune hepatitis (AIH),having a definitive history of medicine taking prior to the onset of disease and accepted liver biopsy were retrospectively analyzed.The general information was collected,which included gender,age,onset of the disease,medication,clinical manifestations,treatment and follow-up.The laboratory findings were also collected,which included total bilirubin (TBil),direct bilirubin (DBil),alanine transaminase (ALT),aspartate transaminase (AST),alkaline phosphatase (ALP),gamma glutamyl transpeptidase (GGT),globulin,γ-globulin percentage,albumin (Alb),eosinophils,antinuclear antibodies,antimitochondrial antibodies,anti-smooth muscle antibodies and the type of live injury.The liver tissue sections of patients were stained with hematoxylin-eosinstaining (HE) and reticular fiber staining and then pathological changes were observed.Patients with DI-AIH were scored with AIH scoring scale.Results All five patients with DI-AIH were female,average age was 48.0--+7.5.Prior to the onset of disease,all patients had taken Chinese traditional medicine.Anorexia and fatigue were the most common clinical symptoms.Among laboratory findings,the level of ALT ((795.0+467.4) U/L),AST ((730.44-451.5) U/L),TBil ((80.3-+ 64.1) μmol/L) and DBil ((65.2 +_ 58.0) μmol/L) significantly increased.One patient was antinuclear antibody positive.One patient had drug-induced liver injury,pathological features were spotty necrosis of liver cells,liver tissue eosinophil infiltration and liver cell microbubble type degeneration.All the patients had interface hepatitis,periportal infiltration of lymphocytes or lymphocytes-plasma cells,liver cells adjacent to lesion showed rosette-like structure.All the patients received glucocorticoid treatment.After glucocorticoid withdrawal,the liver function was normal during the follow-up period.Conclusion There are no specificity of clinical manifestations,laboratory findings and histological features in patients with DI-AIH.
