Recurrent Glomerulonephritis in Renal Transplantation: Experience in Our Renal Transplantation Center.

Abstract

BACKGROUND:

Post-transplant recurrent glomerulonephritis (RGN) is the third cause of graft failure in the first year after renal transplantation (RT). The purpose of this study was to analyze the incidence of RGN, clinical presentation, and clinical evolution of transplanted renal graft in patients who underwent RT at our center.

METHODS:

We studied patients with glomerulonephritis (GN) who underwent RT (2007 to 2013).We analyzed sex, age, time in dialysis, type of GN, type of RT, time to post-transplant RGN, kidney function at the time of diagnosis of RGN, and renal graft evolution. Renal biopsy samples were processed in the anatomic pathology laboratory.

RESULTS:

Three hundred sixteen patients received kidney transplantation during this time period. In 83 cases, the reason for transplantation was primary GN. Of these 83 patients, 15 (18%) had RGN confirmed by renal biopsy. Data for these 15 patients include sex: 73.3% men, 26.7% women; mean age: 42.2 (29-73) years; type of RT: 80% cadaveric donor (CD) versus 20% living donor (LD); type of GN: 18.4% immunoglobulin (Ig)A nephropathy, 35.7% membranous GN, 10.53% type I membrano-proliferative GN (MPGN I), and 16.6% focal segmental glomerular sclerosis (FSGS). The mean time to post-transplant RGN was 2 years (1 month to 16 years). Patients who received an LD transplant had a shorter time to post-transplant RGN than those who had a CD transplant. One patient with FSGS and one with MPGN I had a time to post-transplant RGN of less than 1 year. In the evolution of renal function, 33.3% of patients had graft failure.

CONCLUSIONS:

The incidence of RGN was lower (18%) than that published in the literature. Membranous nephropathy was the most frequent cause of post-transplant RGN. Patients who underwent LD transplantation and those with IgA nephropathy had a shorter interval of time to post-transplant RGN than patients with FSGS and MPGN I.
