Treatment Response and Outcome with Two Different Prednisolone Regimens in Autoimmune Hepatitis

Abstract

Background

Beyond available guidelines, therapy of autoimmune hepatitis (AIH) shows wide variation among physicians. We compared two regimens for treatment naive AIH: one recommended protocol with an initial prednisolone dose of 30 mg/day and our own 40 mg/day prednisolone with a slow dose tapering protocol. We analyzed the safety, response rates, and outcomes for two groups of treated patients.

Patients and Methods

We retrospectively evaluated data of 71 AIH patients including, group I (n = 32, prednisone 30 mg/day) and group II (n = 39, prednisone 40 mg/day). All patients also received azathioprine.

Results

The frequency of complete biochemical response was significantly higher in group II than in group I (69.2 vs. 43.8%, p = 0.031) after 3 months of therapy, but not after 6 and 12 months (79.5 vs. 59.4%, p = 0.065 and 89.5 vs. 80.6%, p = 0.30). In patients with severe interface hepatitis, the complete response rates were significantly higher in group II than in group I after 3 (63.6 vs. 23.1%, p = 0.02) and 6 months (72.7 vs. 38.5%, p = 0.046), but not after 12 months of therapy (86.4 vs. 69.2%, p = 0.221). Relapses were observed in 50% of group I and in 35.9% of group II during maintenance therapy (p = 0.23). Overall survival was significantly better in group II than in group I (100 vs. 87.5%, log-rank, p = 0.048). No severe steroid-related side effects were observed in either group.

Conclusions

Our real-world experience suggests that an initial prednisolone dose of 40 mg/day with a slower tapering protocol induces earlier biochemical response, tends to result in less relapses during maintenance, and is associated with a better disease outcome.
