| Summary: | Background The risk factors for membranous nephropathy (MN) following kidney transplantation remain unclear, mainly attributed to the constrained identification of predictive clinical presentation features. This study aims to conduct a systematic review to analyse the risk factors associated with recurrent MN.Methods Starting from its establishment until March 2023, we conducted a screening of case–control studies focusing on recurrent MN in various databases including PubMed, Embase, Web of Science, Medline, the Cochrane Library, CNKI, Wanfang, CBMdisc and Weipu. The protocol was registered on PROSPERO (CRD42022315448). A meta-analysis was carried out to examine the risk factors for recurrent MN, and statistical analysis was performed using Stata 12.0.Results This meta-analysis included a total of eight case–control studies with 108 patients with recurrent MN and 298 without recurrence. The results showed the incidence of recurrent MN after kidney transplantation was 34%. A higher rate of recurrent MN detected through surveillance biopsies was observed compared to indication biopsies. Living donor [OR = 1.89, 95%CI (1.12, 3.19), and p = 0.017], anti-phospholipase A2 receptor autoantibody (anti-PLA2R) levels before transplantation [OR = 10.16, 95%CI (3.16, 32.62), and p < 0.001] and a shorter duration of dialysis [weighted mean difference (WMD) = −14.36 mo, 95%CI (-24.60, −4.13), and p = 0.006] were associated with a risk for recurrent MN; induction immunosuppression [OR = 0.24, 95%CI (0.10, 0.58), and p = 0.001] and tacrolimus use [OR = 0.23, 95%CI (0.09, 0.61), and p = 0.003] were protective factors for recurrent primary MN, whereas sex, age, time from MN to end-stage renal disease (ESRD), re-transplantation, and race (white) were not associated with recurrent MN.Conclusion Recurrence of MN persists with a high rate. These factors should be carefully evaluated in clinical decision-making, encompassing living donor selection, pre-transplant anti-PLA2R levels, dialysis, choice of induction immunosuppression, and tacrolimus use. |
