ABSTRACT
Objective To investigate the diagnosis and treatment of acute rejection of orthotopic liver transplantation (OLT). Methods From July 1999 to April 2000, two piggyback liver transplantations were performed on two patients with Wilson's disease. Results Cyclosporine A, azathioprine and methylprednisolone were the baseline immunosuppression management. Acute rejection occured 5 times in the 2 patients. The correct diagnosis was obtained through clinical inspection, liver function test and biopsy. The rejections were controlled by intensive steriod therapy plus OKT3 or FK506. Conclusions Clinical inspection and liver function test can suggest the episode of acute rejection in time. Hepatic biopsy is the key point for diagnosis of acute rejecton, Reasonable use of immunosppression is critical for the treatment.
