Is it liverzirrosis (sorry, don´t know the english word) she has?
I just read about something new, developed in Germany, to help in this cases, but I think its still in trial.
You can have a look at www.humanautocell.de, but its in German. If you go to information/kontakt, you can order informations via email. Maybe they do also have something in english...
