Background

Introduction of calcineurin-inhibitor (CNI) has made transplantation a miracle in the past century. However, the side effects of long-term use of CNI turn out to be one of the major challenges in the current century. Among these, renal dysfunction attracts more and more attention. Herein, we undertook a meta-analysis to evaluate the efficacy and safety of calcineurin-inhibitor (CNI) minimization protocols in liver transplant recipients with CNI-related renal dysfunction.

Methods

We included randomized trials with no year and language restriction. All data were analyzed using random effect model by Review Manager 5.0. The primary endpoints were glomerular filtration rate (GFR), serum creatinine level (sCr) and creatinine clearance rate (CrCl), and the secondary endpoints were acute rejection episodes, incidence of infection and patient survival at the end of follow-up.

Results

GFR was significantly improved in CNI minimization group than in routine CNI regimen group (Z?=?5.45, P<0.00001; I2?=?0%). Likely, sCr level was significantly lower in the CNI minimization group (Z?=?2.84, P?=?0.005; I2?=?39%). However, CrCl was not significantly higher in the CNI minimization group (Z?=?1.59, P?=?0.11; I2?=?0%). Both acute rejection episodes and patient survival were comparable between two groups (rejection: Z?=?0.01, P?=?0.99; I2?=?0%; survival: Z?=?0.28, P?=?0.78; I2?=?0%, respectively). However, current CNI minimization protocols may be related to a higher incidence of infections (Z?=?3.06, P?=?0.002; I2?=?0%).

Conclusion

CNI minimization can preserve or even improve renal function in liver transplant patients with renal impairment, while sharing similar short term acute rejection rate and patient survival with routine CNI regimen.
