The objective of this systematic review is to compare the incidence of CMV and BK virus infections in kidney transplant recipients receiving an mTORi-based as compared to a CNI-based regimen.
Methods:We underwent a comprehensive search of literature for RCTs addressing our objective.
Results:We included 33 trials,with 7277 participants,classified in 3 comparisons.Meta-analysis showed a significant reduction of CMV in mTORi groups.
There was a trend towards decreased BK with mTORi.
Meta-analysis for acute rejection showed an increased risk with mTORi in comparison 1 and a similar rate for comparisons 2 and 3.Estimated GFR favored the mTORi group in comparisons 1 and 2, and the CNI-based regimen in comparison 3.
| Comparison | Outcome | Conclusion | Nb of RCTs |
| 1 | acute rejection | increased risk in mTORi(RR 1.35, 95%CI 1.07-1.7) | 19 RCTs, N=3921 |
| eGFR | higher in mTORi(MD 4.07, 95% CI 1.34-6.8) | 18 RCTs, N=3768 | |
| 2 | acute rejection | no difference(RR 0.88, 95% CI 0.7-1.09) | 5 RCTS, N=1553 |
| eGFR | trend towards higher eGFR in mTORi(MD 3.36, 95% CI -4.31,11.02) | 5 RCTs, N=1543 | |
| 3 | acute rejection | trend towards decreased risk in mTORi(RR 0.82, 95% CI 0.64-1.04) | 5 RCTs, N=1128 |
| eGFR | lower in mTORi(MD -5.68, 95% CI -8.64, -2.72) | 3 RCTs, N=539 |
Conclusions: We demonstrated around 50% reduction of CMV infection in mTORi-based regimen. No definite conclusion was possible for BK.Our review suggested that a combination of an mTORi and a reduced dose CNI may offer similar rates of acute rejection, and improved GFR,when compared to a standard CNI-based regimen.
