PG - 1708-13 LID - 10.1093/ndt/gfp693 [doi] AB - We report the development of IgA nephropathy (IgAN) following full myeloablative allogeneic hematopoietic cell transplantation in two patients with human leukocyte antigen (HLA) matched sibling donors, unrelated to active or chronic graft-versus-host disease. Both recipients had elevated urinary levels of galactose-deficient IgA1, and one donor-recipient pair had elevated serum levels of galactose-deficient IgA1. We propose that IgAN developed after bone marrow transplantation due to a non-graft-versus-host-disease-related multi-hit process associated with glomerular deposition of galactose-deficient IgA1. These two cases provide unique insight into the kinetics of overproduction of galactose-deficient IgA1 and its glomerular deposition and consequential renal injury in IgAN.
