Background: The purpose of this study was to detect the efficacy and safety of tacrolimus (TAC) in induction therapy of patients with lupus nephritis.
Methods: Associated studies were extracted from the PubMed and the Cochrane Library on July 10, 2018, and applicable investigations were pooled and analyzed by meta-analysis. Data on complete remission (CR), total remission (TR; complete plus partial remission), proteinuria levels, urine erythrocyte number, albumin, glomerular filtration rate, negative rate of ds-DNA, C₃ levels, C₄ levels, systemic lupus erythematosus disease activity index (SLE-DAI), etc, were extracted and pooled using RevMan 5.3.
Results: In the therapeutic regimen of TAC + glucocorticoids (GC) vs cyclophosphamide (CYC) + GC, the results indicated that the TAC group had high values of CR, TR, albumin, and negative rate of ds-DNA, and low values of proteinuria levels and SLE-DAI when compared with those in CYC group (all P <0.05). In the therapeutic regimen comprising TAC + GC vs mycophenolate mofetil (MMF) + GC, the results indicated that the difference of CR, TR, proteinuria levels, and albumin between TAC group and MMF group were not significant (all P >0.05). In the therapeutic regimen comprising TAC + MMF + GC vs CYC + GC, multitarget therapy group showed higher values of CR, TR, urinary protein decline, and rise of serum albumin when compared with CYC group (all P <0.05).
Conclusion: TAC is an effective and safe agent in induction therapy of patients with lupus nephritis.
