Objective To investigate the metabolic differences of Tacrolimus in different transplant recipients. Methods A retrospective study was conducted, 30 patients of the organ transplant admitted to organ transplantation center of General Hospital of Chinese People's Armed Police Forces from January 2002 to August 2012 were enrolled, and they were divided into combined liver and kidney transplant (SLK) group, single liver transplant group and single renal transplant group, 10 cases in each group. The SLK group and the simple liver transplantation group were given the same drug regimen, methylprednisolone injection was given during operation, and tacrolimus+ mycophenolate mofetil+ prednisone triple immunosuppressive therapy was taken after operation, on the first day after operation, the initial dose of tacrolimus was given 0.06 mg·kg-1·d-1 divided into 2 times taken orally, and on the third day after operation, the concentration of tacrolimus was detected; after operation group for 2 - 4 days, single renal transplantation group was given tacrolimus the initial dose of tacrolimus 0.15 mg·kg-1·d-1 was divided into 2 parts for twice oral administration, after 2 - 3 days of the above treatment, monitoring the concentration of tacrolimus began. One month after transplantation, the metabolic differences of tacrolimus among the three groups were compared.Results One month after operation, the oral tacrolimus doses (μg·kg-1·d-1: 74.78±32.65 vs. 80.62±24.02, 85.58±16.78) and the monitored blood drug concentration (μg/L: 6.64±2.73 vs. 7.50±3.08, 7.46±3.20) in SLK group were lower than either the single liver transplantation group or single renal transplantation group, but the comparisons among the three groups, there were no statistically significant differences(allP > 0.05).Conclusions In SLK group, the protective effect of transplanted liver on transplanted kidney may be related to the length of postoperative time. Liver transplantation performed within post-operative one month has no protective effect on the transplanted kidney.
