摘要
AIM: To determine the eff icacy of tacrolimus on clinical status, histopathological status and biochemical markers in patients with steroid refractory autoimmune hepatitis (AIH). METHODS: Retrospectively, clinical parameters, biochemistry and histology were obtained from patient records. RESULTS: Nine patients [8 females/1 male, median age 32 (range 16-64) years] were identified to have received tacrolimus for a median duration of 18 (12-37) mo. Before initiation of tacrolimus treatment the patients were maintained on a prednisolone dose of 20 mg daily (range 20-80 mg/d), which was tapered to 7.5 (5-12.5) mg/d (P = 0.004). Alanine aminotransferase and immunoglobulin-G concentrations decreased from 154 (100-475) to 47(22-61) U/L (P = 0.007), and from 16 (10-30.2) to 14.5 (8.4-20) g/L (P = 0.032), respectively. All patients showed improvement of the liver inflammatory activity, as determined by the Ishak score (P = 0.016), while the degree of f ibrosis tended to decrease (P = 0.049). CONCLUSION: The use of low dose tacrolimus can lead to biochemical and histologic improvement of inflammation with no progression of the stage of f ibrosis in patients with steroid refractory AIH. Low dose tacrolimus therapy also allows substantial reduction of prednisone dose.
