ABSTRACT
Immunosuppressive medications after renal allograft transplantation have impacted the course of acute and chronic rejection: however, they have no defined effects on the prevention of recurrent and Glomerulonephritis (GN) in an allograft kidney. Authors experienced a case of rapidly progressive glomerulonephritis (RPGN). The 35-year-old female patient developed a rapid deterioration of renal function 4 years after renal transplantation. The allograft biopsy showed crescentic glomerulonephritis evolving from membranoproliferative glomerulonephritis (MPGN) type I. She was given pulse steroid and oral cyclophosphamide therapy immediately after the renal biopsy. Graft function stabilized and proteinuria decreased even though graft function did not recover to pre-treatment level and low grade proteinuria persisted.
