Background: Glucocorticoid as the standard treatment of autoimmune hepatitis has been recommended with different doses. The purpose of this study is to compare the efficacy and safety of high and low doses for clinical practice.
Methods: Medline, Embase, and Cochrane Library were searched until January 16th, 2019 for cohort studies or randomized controlled trials in patients with autoimmune hepatitis. Glucocorticoid 60 mg/d or 1 mg/kg/d was defined as high dose and 40 to 50 mg/d or 0.5 mg/d as low dose. Outcome of interests includes the incidence of the biochemical remission, adverse event, and endpoint events. Double arcsine method with a random-effect model was used to combine the incidence. Potential heterogeneity was explored by meta-regression and subgroup analysis.
Results: Overall, 25 studies (3305 patients) were included, with 10 studies in the high dose group and 15 in low dose group. The biochemical remission rate in the high and low dose group was 0.79 (95% confidence interval [CI] [0.72, 0.85]) and 0.72 (95% CI [0.65, 0.78]), respectively. The incidence of endpoint events and adverse event in the high were slightly higher (0.03, 95% CI [0.02, 0.04]; 0.42, 95% CI [0.30, 0.53]) than that of the low dose group (0.01, 95% CI [0.00, 0.01]; 0.39, 95% CI [0.15, 0.63]).
Conclusions: For autoimmune hepatitis patients, 60 mg/d or 1 mg/kg/d of glucocorticoid gives higher biochemical remission rate and higher incidence of endpoint events and adverse events.
