Abstract:
Objective To explore the evidences of the humoral factor involved in the liver allograft rejection, and to explore better monitoring methods and therapy of the humoral liver rejection. Methods After the humoral liver rejection, liver puncture biopsies were performed. Immunohistochemical examinations of C4d, CD20+ B lymphocytes and CD138+ plasma cells were performed to judge whether humoral factor was involved in liver rejection. The dosage of tacrolimus was increased first when rejection was identified. The patients with severe liver function damage were treated with methyllprednisolone, and the steroid-insensitive cases were treated with antithymocyte globulins (ATG) and rapamycin. Results 25 biopsies were performed in 16 patients. Humoral rejection was diagnosed for 15 times in 10 patients, cellular rejection was diagnosed for 6 times in 4 patients, and the both kinds of rejection occurred in the last 2 patients. The effect of methylprednisolone was obviously lower in the humoral rejection cases (29.4%, 5/17) than that of the cellular rejection cases (7/8). Steroid-insensitive humoral rejections were diagnosed in 12 biopsies from 7 patients receiving liver transplantation. One patient was cured with ATG and 5 patients were cured with addition of rapamycin. The case whose blood type was AB receiving a liver transplant from the donor of O blood type died of liver function failure even after an extensive treatment. Conclusions Humoral immune factors maybe involved in some acute and chronic liver allograft rejection. ATG and rapamycin are more effective for the patients with humoral liver rejection.
