She had chronic liver problem (liver scan showed rough surface) before transplant but had no HCV.
For the last one year, her liver enzymes have been very high (GGT can touch 1800, for example). When that happens, the doctor increases PanGraf / Cellcept dosage and a particular steroid (wysolone). After that the enzymes go back to normal - except GGT which goes down but still remains well above normal (say, falls from 1800 to 300).
