Successful treatment of resistant antiglomerular basement membrane antibody positivity with mycophenolic acid.

Anti-glomerular basement membrane (GBM) antibody disease may progress to end-stage renal failure, requiring either dialysis or renal transplantation. In patients with end-stage renal disease (ESRD) due to anti-GBM-ab disease, the recurrence rate after transplantation is as high as 50% (2) and delaying renal transplantation until circulating anti-GBM antibody levels have been undetectable for at least 12 months reduces the recurrence rate to 5-15%. We report a case of ESRD due to renal limited anti-GBM disease with circulating anti-GBM-ab resistant to standard treatment approach who achieved undetectable anti-GBM-ab with mycophenolic acid.
