Kidney transplantation for end-stage renal disease in lupus nephritis, a very safe procedure: a single Latin American transplant center experience.

ABSTRACT

Background Lupus nephritis (LN) is one of the most frequent complications of SLE and occurs in up to 50% of cases depending on the studied population. Of these, approximately 20% progress to end-stage renal disease (ESRD), with the treatment of choice being a kidney transplant. Objective The objective of this study was to describe the clinical outcome of patients transplanted due to LN, compared with patients transplanted for other causes, in a Latin American population from the Fundación Valle del Lili in Cali, Colombia. Methods Observational, retrospective case study with controls matched by age, sex and type of donor in a single center between 1996 and 2014. Results Sixty-five kidney transplants were performed in patients with LN and ESRD. The survival of patients with LN was 98% at 1, 10 and 15 years ( p = .99). For controls by age and sex, survival was also 98% at 15 years post-transplant, and for controls by donor, the survival rate was 100% at 5 years and 98% at 15 years. Graft survival in patients with LN to 1, 5 and 15 years was 92%, 83% and 71%, respectively; for controls by age and sex, it was 90%, 84% and 64%, respectively, and for the controls by donor, it was 89%, 86% and 79%, respectively ( p = .7718). There were no statistically significant differences found in the cumulative incidence of acute graft rejection in the first year, but it was found that acute rejection is a factor that relates to the loss of function of the renal graft ( p = .032). Of the patients transplanted for LN, two (3.1%) experienced a recurrence of the disease. One patient died after a diagnosis of recurrence of LN due to an infection. Conclusions Kidney transplantation is a good option for patients with ESRD due to LN. In this Hispanic population, the survival of patients, graft survival, and cumulative incidence of graft rejection are not different from those of other transplanted patients. In addition, recurrence of LN was rare, showing the benefits of renal transplantation in LN patients with ESRD.
