Renal allograft glomerulonephritis.

The analysis of 1282 renal transplantations revealed 14 cases of allograft glomerulonephritis (GN). Membranous GN was found in seven patients, in four of whom the GN appeared de novo. IgA GN was evident in three cases and focal segmental glomerulosclerosis and mesangiocapillary GN type 1 in two cases each. The signs of GN were detected 0.5-72 months after transplantation. The most common clinical sign indicating an allograft biopsy was nephrotic syndrome. Deterioration of the graft function was often seen and it was usually associated with chronic rejection.
