BACKGROUND: Clinical manifestations and risk factors associated with systemic lupus erythematosus (SLE) flares, including recurrent lupus nephritis (LN), in patients with LN who undergo kidney transplantation have been unclear.
METHODS: Kidney transplant recipients with LN from January 1995 to December 2021 were included in this study. A disease flare was defined as either an increase in the non-renal SLE disease activity index score or the presence of biopsy-proven recurrent LN.
RESULTS: Among a total of 93 patients with LN who underwent kidney transplantation, 11 patients (11.8%) experienced SLE flares during a median follow-up period of 76.9 months (IQR, 43.0-122.4). The most common clinical manifestations of SLE flares were recurrent LN (4/11, 36.4%) and hematologic manifestations (4/11, 36.4%). Patients who had flares had significantly higher anti-double-stranded DNA (anti-dsDNA) antibody titers both before and after transplantation. Furthermore, an increased anti-dsDNA antibody level before transplantation was associated with a high risk of an SLE flare (HR, 1.030; p = .008). Conversely, preemptive transplantation was associated with a lower risk of a flare (HR, 0.617; p = .026). The rate of patient death-censored graft survival was found to be considerably lower in patients with recurrent LN than in those without LN.
CONCLUSIONS: Approximately 10% of patients with LN experienced an SLE flare after transplantation, with recurrent LN being the most frequent manifestation. Anti-dsDNA antibody titers before transplantation were significantly related to the risk of an SLE flare. Notably, preemptive transplantation was associated with a reduced risk of flares following transplantation.
