Outcome of orthotopic liver transplantation in autoimmune hepatitis according to subtypes.

The relevance of autoimmune hepatitis (AIH) classification for clinical purposes is controversial. We analyzed the outcome after orthotopic liver transplantation (OLT) of nine type I and seven type II AIH patients. Type II patients had a significantly higher incidence of cirrhosis at the time of diagnosis, more resistance to steroid therapy, and a higher Child-Pugh score at the time of OLT. OLT was performed in emergency in three type II patients and electively in all type I patients. Four type II and one type I patients died in the postoperative period. There was no difference regarding the incidence of post-OLT infection and rejection between the two types. No recurrence of AIH was observed. The 6-year actuarial survival rates for type I and type II patients were 76% and 43%, respectively. Type II AIH patients who have a poor response to medical therapy should be considered for OLT with a shortened delay.
