title: Glomerular lesion and increased cytokine gene expression in renal tissue in patients with decompensated nephrotic syndrome due to chronic GvHD.
abstract: The nephrotic syndrome is a rare complication of allogeneic stem cell transplantation (alloHSCT). We present two cases of nephrotic syndrome during chronic graft-versus-host disease (GvHD) involving altered cytokine gene expression in renal tissue. A patient with acute lymphatic leukemia demonstrated nephrotic syndrome due to minimal change disease as a marker of chronic GvHD. A patient with acute lymphoblastic leukemia suffered from severe nephrotic syndrome due to membranous glomerulopathy. In the two presented cases of GvHD-linked nephrotic syndrome, increased cytokine gene expression [tumor necrosis factor alpha (TNF-alpha), transforming growth factor beta (TGF-beta), interferon gamma (IFN-gamma), interleukin 2 (IL-2), IL-6, and IL-10] assessed using semiquantitative evaluation with reverse transcriptase polymerase chain reaction (RT-PCR) in situ on renal biopsy was observed.
