title: Glomerular diseases associated with chronic graft-versus-host disease after allogeneic peripheral blood stem cell transplantation: case reports.
abstract: Chronic graft-versus-host disease (cGVHD) is the major complication following allogeneic stem cell transplantation (allo-SCT). Nephrotic syndrome (NS) and other types of glomerulonephritis have been proposed to be the very rare forms of renal cGVHD. From 1991 to 2011, 253 patients underwent allo-SCT at our center. We report here 4 cases (1.6%) presenting with varieties of glomerular manifestations associated with cGVHD. The first case was typical NS. The renal pathology showed membranous nephropathy (MN). The second case was also MN, but this patient also had the pathology of focal segmental glomerulosclrosis (FSGS) and acute tubular necrosis (ATN). The third case showed lupus nephritis-like glomerular lesions with a high anti-nuclear antibody (ANA) titer. The fourth case presented with rapidly progressive glomerulonephritis (RPGN)-like symptoms. The kidney histology in this case was not available. The patient responded well to immunosuppressive therapy, but NS later recurred. Therefore, overt glomerular diseases after allo-SCT in Thai patients are not very rare. Monitoring urinalysis during withdrawal of immunosuppressive drugs and also during follow-up of patients with cGVHD may be considered.
