Abstract:
Objective To report the results of a single-center, retrospective study on the effect of calcineurin inhibitors (CNI) withdraw for controlling infections and conversion to sirolimus (SRL)for ameliorating renal dysfunction. Methods A total of 947 liver transplant cases from 2002 to 2010were divided into two eras (Jan. 2002 to Dec. 2007 and Jan. 2008 to Dec. 2010). There were 234cases of infections after liver transplantation (LT) in the first era and 101 cases in the second era. And of 329 cases of CNI-related renal dysfunction after LT in two eras, 40 cases (converting group) had converted CNI to SRL, while 289 cases (reducing group) adopted protocol of CNI reducing and mycophenolate mofetil (MMF) raising. Results CNI-based IS took up 95.8 %, 95. 3 %, 97. 5 % of the IS protocols with recipient survival time longer than 1, 3, and 5 years. The primary cause for CNI withdraw was infection (88. 2 %, 15/17) in the second era, and renal dysfunction for conversion to SRL in the two eras (83. 3 %, 40/48). In the second era, 14. 9% (15/101) of the cases of infections after LT experienced CNI withdraw. Of the 15 patients, 11 had effectively controlled the infection (77. 3 %) while rejection rate was 6. 7 % (1/15). The cumulative survival rate of the second era was significantly higher than the first era (P＜0. 05). The glomerular filtration rate (GFR) of converting group at 6th week and 6th month was statistically elevated as compared with that before conversion,respectively (1.28 ± 0. 31, 1.36 ± 0. 32 mL/s vs. 0. 82 ± 0. 24 mL/s, P＜0. 05). Six months after CNI adjustments, survival rate of converting group and reducing group was 85. 0% and 83. 7 %,respectively (P＞0. 05). Conclusion Reducing or even short-term withdraw of CNI may allow the better control of infections after LT, and the conversion from CNI to SRL can ameliorate the CNIrelated nephrotoxicity. These individually tailored IS protocols will benefit the long term survival for LT.
