Everolimus treatment for patients with autoimmune hepatitis and poor response to standard therapy and drug alternatives in use.

OBJECTIVE: Not all patients with autoimmune hepatitis (AIH) respond to standard medical therapy with corticosteroids and azathioprine. Such patients may develop end-stage liver disease with poor prognosis unless transplantation is considered. Alternatively, the introduction of new therapeutic strategies could potentially ameliorate deterioration of liver function. Patients in our tertiary center were selected for everolimus therapy when exhibiting nonresponse or intolerance to combinations of the standard and empirical drugs in use (e.g., mycophenolate mofetil, calcineurin inhibitors [CNIs]). We here report the efficacy of everolimus treatment of patients with AIH.
MATERIALS AND METHODS: Seven patients (six female, mean age 47 years, range 22-62 years) in whom disease control could not be achieved with standard therapy or the alternative drugs in use were included.
RESULTS: Treatment with everolimus induced a clear reduction of transaminases within 2 weeks. After 3-5 months three patients had normal alanine aminotransferase (ALT) levels (10-45 IU) and four patients had ALT levels below 55 IU compared to a three- to fivefold elevated level prior to everolimus treatment. Sustained remission after 1 year of treatment was observed in three patients; in another two patients ALT was 45-68 U/L. Four patients in remission after 3 years were rebiopsied. Two showed no histological progression, and in two the fibrosis had decreased. Side effects noted were myalgias and minor bacterial infections not leading to discontinuation of the drug.
CONCLUSION: Our experience indicates that everolimus may be of value in selected patients with therapy-resistant AIH and comorbidity/side effects that excludes the use of CNIs.
