Complications associated with kidney transplantation, causes of graft failure and mortality following kidney transplantation in patients with systemic lupus erythematosus: a meta-analysis
Abstract
Abstract Introduction Despite improvement in the management of systemic lupus erythematosus (SLE) during the past two decades, 10–22% of patients with lupus nephritis (LN) will progress to end-stage renal disease (ESRD). Kidney transplantation is among the possible treatment for patients with SLE progressing to ESRD. However, the issue with kidney transplantation in patients with SLE is controversial. In this analysis, we aimed to compare the complications associated with kidney transplantation, causes of graft failure and causes of mortality following kidney transplantation in patients with SLE with ESRD. Methods The sources of data included http://www.ClinicalTrials.gov , EMBASE, MEDLINE, Google Scholar, Web of Science and the Cochrane database. Revman software version 5.4 was used for the data analysis whereby risk ratio (RR) with 95% confidence intervals (CI) were used to represent data following analysis. In addition, the Q statistic test and the I 2 statistic test were used to assess heterogeneity. A random effect statistical model was used and a subgroup outcome with a P-value less than 0.05 was considered statistically significant. Results A total number of 149,330 participants enrolled between the years 1968 and 2018 were included in this analysis with 7534 participants with SLE. Results of this analysis showed that mortality (RR 1.07, 95% CI 0.89–1.29; P = 0.45), graft failure (RR 1.22, 95% CI 0.99–1.55; P = 0.07) and delayed graft function (RR 1.01, 95% CI 0.44–2.34; P = 0.98) were not significantly higher in renal transplant patients with SLE versus a control group. When the causes of graft failure were analysed in renal transplant patients with SLE versus without SLE, acute graft rejection (RR 1.20, 95% CI 0.98–1.47; P = 0.07), chronic graft rejection (RR 0.76, 95% CI 0.57–1.03; P = 0.08), graft thrombosis (RR 1.47, 95% CI 0.83–2.63; P = 0.19), recurrence of disease (RR 3.08, 95% CI 1.00–9.47; P = 0.05) and chronic allograft nephropathy (RR 1.08, 95% CI 0.60–1.95; P = 0.80) were also not significantly higher in patients with SLE. On the basis of the analysis, mortality from any cardiac cause (RR 0.82, 95% CI 0.67–1.01; P = 0.06), sepsis (RR 1.19, 95% CI 0.93–1.53; P = 0.17), malignancy (RR 0.79, 95% CI 0.51–1.24; P = 0.31) and cerebrovascular attack (RR 0.76, 95% CI 0.44–1.30; P = 0.31) were not significantly different in kidney transplantation patients with versus without SLE. Conclusions Complications associated with kidney transplantation including mortality, graft failure and delayed graft function were not significantly higher in patients with SLE when compared with a control group. The causes of graft failure and mortality after kidney transplantation were also comparable in both groups. Therefore, kidney transplantation represents a promising treatment in patients with SLE with ESRD.
