Material and methods. In a 30-year (1989–2018) retrospective study conducted from 2007 to 2012, there were statistically significant differences in estimated glomerular filtration rate (eGFR, ml/min/1.73 m2) between the two KTR groups receiving CsA or TL respectively. Patients receiving TL were younger, more male, and had better survival (p<0.05). We performed a meta-analysis to compare the effects of CsA and TL on GFR and survival. The electronic PubMed, MEDLINE, Scopus and the Cochrane Library databases were searched for studies comparing maintenance immunosuppression options based on TL and CsA in the experimental and control groups, respectively, for at least a year after kidney allotransplantation. The primary outcome of the study was patient survival, the secondary outcome was renal graft function, determined by creatinine clearance (GFR, ml/min) according to the Rehberg test or the Cockcroft-Gault formula, or by eGFR in the CKD-EPI, MDRD, Nankivell equation. Meta-analysis of proportions was performed using the Freeman–Tukey transformation to calculate weighted summary proportions from a fixed and random effects model. Odds ratios (ORs) were used to assess dichotomous variables, and mean differences (MDs) and 95% confidence intervals (CIs) for both variables were used for continuous variables. Of the total 678 studies found, 16, including our own, were included in the systematic review and meta-analysis, with a total of 12,181 patients (treatment n=6504 and control n=5677 groups).
Results. The meta-analysis included 12 randomized and 4 non-randomized controlled trials. There were no differences between the two groups in age, sex, creatinine level, or patient survival. GFR was significantly higher for TL-based immunosuppressive regimens than for CsA in the fixed model (HR=0.451, 95% CI 0.39 to 0.5; p<0.001) and in the random model (HR=0.641, 95% CI from 0.286 to 0.996; p<0.001). Meta-analysis data on GFR were significantly heterogeneous: I2=96.96%, 95% CI 95.8 to 97.79, Q test; p < 0.0001, however, Begg's test (p=0.815) and Egger's test (p = 0.456) do not suggest the presence of publication bias in this case.
Conclusion. A meta-analysis showed that, compared with CsA, TL has an advantage only in its effect on GFR. Differences in baseline GFR determination and creatinine calibration may likely explain the heterogeneity of findings in this meta-analysis. These factors should be considered by researchers and clinicians when interpreting GFR estimates. In this regard, the use of a single eGFR for KTR is relevant.
