Hello and welcome to HCM
I assume that the diagnosis of autoimmune hepatitis
is made on biopsy
Autoimmune hapatitis is a progressive disease but there are medications which antagonize the antibodies
produced by the body.
When medical treatment is not effective liver transplant
is being done in good number of centres all over the world.
So, consult a hepatologist and discuss the further management for the problem.
Console your friend that there is no need to be disheartened.
Thanks and take care
