    Abstract:
    INTRODUCTION: The recurrence of IgA nephropathy (IgAN) after kidney transplantation (KT) has an effect on graft survival, but there are few reports about long-term clinical outcomes of KT with recurrent IgAN. This study shows the long-term clinical outcomes of KT in patients with IgAN. METHODS: All recipients who had biopsy-proven IgAN were followed from February 1990 to February 2016. We analyzed overall graft and patient survival rates, incidence of recurrent IgAN, factors affecting graft survival, and IgAN recurrence. RESULTS: There were 88 patients with first KT. The mean follow-up duration was 82.5 months. Twenty patients went through graft loss and 1 patient died due to sepsis. IgAN recurred in 15 patients, and 11 patients experienced graft failure. Among the patients who had failed graft after first KT, 7 patients underwent retransplantation. The graft survival period, presence of rejection, and proteinuria were the relevant risk factors for recurrence of IgAN. In the first KT patients, presence of rejection and 1-year serum creatinine were the significant risk factors for graft loss. But recurrence of IgAN was not a relevant risk factor. Overall graft survival rates at 5 and 10 years were 93.8% and 73.1% in the first transplantation group and 100% and 100% in the retransplantation group, respectively. CONCLUSION: Although IgAN recurrence was a significant risk factor for graft failure, the patient who underwent retransplantation showed favorable results. Retransplantation should be considered in patients who lost their first graft after recurrence of IgAN.
