Objectives: End-stage renal disease develops in a high percentage of patients with vasculitis, in whom kidney transplant has become a therapeutic option. However, limited data are available on the prognosis and outcomes after kidney transplant in these patients. We aimed to compare the long-term graft survival and graft function in 8 renal transplant recipients with vasculitis (granulomatosis with polyangiitis, microscopic pol yangiitis, Goodpasture syndrome, and Henoch-Schönlein purpura) with the other kidney recipients at a single center.
Materials and Methods:We conducted a retrospective study of patients followed for chronic renal failure associated with vasculitis before renal transplant. We excluded patients with no biopsy-proven nephropathy. Results: There was no difference in the occurrence of metabolic and cardiovascular complications in our case group compared with the other graft recipients. Infections were frequent and included cytomegalovirus and urinary tract infection. The rates of bacterial and viral infection were equivalent in our population. The incidence of allograft loss was estimated at 1.8%, less than that seen in our entire transplant population. The presence of vasculitis was not significantly related to renal failure (P = .07). Extrarenal relapse occurred in 1 patient with microscopic polyangiitis. Antineutrophil cytoplasmic antibody levels in patients with granulomatosis with polyangiitis and microscopic polyangiitis did not seem to influence the renal outcome (P = .08). Circulating antineutrophil cytoplasmic antibodies were associated with the development of vascular lesions in the graft but were not significantly correlated with graft survival (P = .07). Conclusions: This study supports the theory that renal transplant is an effective treatment option for patients with end-stage renal disease secondary to vasculitis. These patients fare similarly to, if not better than, other patients.

IntroductionRenal vasculitis results in end-stage renal disease in 20% to 40% of patients. 1-3 Data from small case series indicate that recurrence of vasculitis after transplant is infrequent and is rarely associated with graft loss, 4-6 whereas relapse rates are below those reported in the entire transplant population. 7 We aimed to highlight the outcome of renal transplant (RT) in a case series of 8 patients with renal vasculitis followed at a single transplant unit.
Materials and MethodsOur cohort of 8 patients included 3 patients diagnosed with granulomatosis with polyangiitis (GPA), 1 with microscopic polyangiitis (MPA), 2 with Goodpasture syndrome, and 2 with Henoch-Schönlein purpura (HSP). All patients were treated between 1986 and 2015, and all relevant data were gathered using patient record review. We compared vasculitis patients with all other patients who underwent RT at our center to determine the correlation between vasculitis and the occurrence of me...
