The outcome of kidney transplantation in lupus patients

Type: article

Abstract: BACKGROUND: Kidney transplantation represents a therapeutic option for individuals with end-stage renal disease due to lupus. However, the influence of lupus activity and immunosuppressive medications on graft survival remains a matter of concern and it has not been thoroughly elucidated. METHODS: In this study, we conducted a retrospective review of 45 lupus patients who underwent kidney transplantation, with the aim of analyzing graft survival and identifying factors influencing the outcome of kidney transplantation in lupus patients. RESULTS: Graft survival rates at 1, 5, 10, 15, and 20 years were 98%, 98%, 88%, 85%, and 78%, respectively. Univariate logistic regression revealed hypertension, positive panel reactive antibodies against HLA class II antigens, retransplant, young age at lupus nephritis onset, low postoperative C4 levels, and HBsAg and/or anti-HBe antibody presence were significantly correlated with decreased graft survival (p < 0.05). Multiple regression confirmed the significant association of HBsAg and/or anti-HBe antibody with graft failure (p = 0.0161), with all patients testing negative for anti-HBc antibody. Preoperative markers (C3, C4, anti-dsDNA antibody) and recurrent lupus nephritis did not impact graft failure. CONCLUSION: In lupus patients undergoing kidney transplantation, hepatitis B serology emerges as a potential singular predictor for graft failure, while preoperative lupus activity markers and recurrent lupus nephritis do not affect outcomes.
