Abstract:
Objective Based on detection of the soluble LAIR-1 (sLAIR-1) and sIL-2R in the bile from recipient after liver transplant, the role of sLAIR-1 and sIL-2R in graft acute rejection were analyzed. Methods Bile sLAIR-1 level and sIL-2R were determined by double mAb sandwich enzyme linked immunosorbent assay in 55 cases of liver transplantation. Results In 22 recipients with normal graft function, sLAIR-1 and sIL-2R were detected at low level in the bile. In the 29 cases of liver acute rejection (AR), significant increase of bile sIL-2R level was detected on the lst and 2nd d before final diagnosis. With the effective methylprednisolone pulse therapy, sIL-2R level was decreased significantly on the 3rd d. On the other hand, remarkable increase of bile sLAIR-1 was found on the lst,2nd and 3rd d before final diagnosis. After of methylprednisolone pulse therapy for 3 d, bile sLAIR-1resturned to the control level. Conclusion Both bile sIL-2R and sLAIR-1 are detected at high level in the recipients suffering from liver acute rejection. The level of bile sLAIR-1 changes dramatically and responsively according to liver acute rejection. Therefore, detecting these two markers synergistically may be a promising monitor for rejection after liver transplantation.
