A 32-year-old man with graft loss due to chronic rejection received a 2nd kidney allograft from a living donor in the left iliac fossa, while the 1st was left in the contralateral side. An episode of acute rejection occurred at 1 month, resolved by steroid therapy. The 2nd allograft developed chronic allograft nephropathy, resulting in graft failure after 30 months of retransplant. Contrast-enh...
Apolipoprotein L1 gene (APOL1) nephropathy variants in African American deceased kidney donors were associated with shorter renal allograft survival in a prior single-center report. APOL1 G1 and G2 variants were genotyped in newly accrued DNA samples from African American deceased donors of kidneys recovered and/or transplanted in Alabama and North Carolina. APOL1 genotypes and allograft outcom...
Since the mid-1980s magnetic resonance imaging (MRI) has been investigated as a non- or minimally invasive tool to probe kidney allograft function. Despite this long-standing interest, MRI still plays a subordinate role in daily practice of transplantation nephrology. With the introduction of new functional MRI techniques, administration of exogenous gadolinium-based contrast agents has often b...
BK virus is a human polyoma virus that may cause nephropathy in immunosuppressed patients. It is a well-recognized cause of renal allograft dysfunction and allograft loss in renal transplant recipients, but it is an infrequent cause of nephropathy outside this setting. There are a few case reports of BK virus nephropathy in the native kidneys of immunosuppressed adult patients with non-renal tr...
background: regulatory t cells have been suggested to have a protective role against acute rejection in allograft recipients. however, there is little information available about their contribution to chronic rejection process. the role of transforming growth factor-beta 1 (tgf- β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. objectives: to eva...
