Kidney transplantation in Alport's syndrome: long-term outcome and allograft anti-GBM nephritis.
Anti-glomerular basement membrane (anti-GBM) nephritis occurring in kidneys transplanted in patients with Alport's syndrome (AS) has been reported repeatedly. Therefore, we studied graft survival and course of renal function in all 30 AS patients grafted at Hannover Medical School and compared them with non-diabetic, age and sex matched patients, transplanted on the date closest to the transplantation of the AS patient. Serum creatinine, proteinuria, urinary sediment and anti-GBM antibodies were examined in all AS patients with functioning grafts. Cases of patient or graft loss in the AS group were analyzed retrospectively. One- and five-year patient survival was 100 and 91% in AS and 89 and 78% in controls (p > 0.05, respectively). One- and five-year first graft survival was 79 and 66% in both groups. Graft histology was available in 34 biopsies obtained from 21 kidneys in 15 AS patients. Anti-GBM nephritis was not detected in any of the biopsies. No graft was lost due to anti-GBM nephritis. Anti-GBM antibodies were detectable temporarily only in one AS patient. He also had linear IgG staining in his graft GBM, but no other signs of anti-GBM nephritis. We conclude that patient survival and graft survival in AS patients following kidney transplantation is not different from non-AS patients. Allograft anti-GBM nephritis is a rare complication in patients with Alport's syndrome.
