Immediate post-transplant nephrosis in a patient with congenital nephrotic syndrome

A 19-month-old girl with congenital nephrotic syndrome of the Finnish type underwent a living-related renal transplant; 24 h after transplantation she became massively nephrotic. She did not respond to steroids, plasmapheresis, and high-dose cyclosporine. A month later, a renal biopsy showed only glomerular foot process effacement. She was treated with high-dose methylprednisolone pulses and oral cyclophosphamide. She rapidly went into complete remission with no further relapses. Graft function has been stable 2 years after transplantation.
