Recurrent minimal change disease post-allograft renal transplant

Area of Science:

• Nephrology
• Transplantation Immunology
• Renal Pathology

Background:

• Minimal change disease (MCD) is a primary cause of nephrotic syndrome, often responsive to steroids.
• Steroid-resistant MCD presents a therapeutic challenge, with limited treatment options and potential for progression.
• Kidney transplantation is a treatment option for end-stage renal disease, but recurrence of primary glomerular diseases is a known complication.

Observation:

• A young adult with biopsy-confirmed steroid-resistant MCD, without evidence of FSGS, underwent kidney transplantation.
• Post-transplant, the patient developed recurrent nephrotic syndrome and renal insufficiency, despite aggressive management.
• Histopathological examination of the explanted graft confirmed MCD morphology, ruling out FSGS.

Findings:

• The patient experienced recurrence of minimal change disease in the allograft shortly after transplantation.
• Despite treatment, graft function did not improve, necessitating graft nephrectomy.
• This represents the first documented case of recurrent MCD following kidney transplantation.

Implications:

• Recurrence of MCD post-transplant can lead to graft failure and presents a significant clinical challenge.
• Further research is needed to understand the mechanisms of MCD recurrence and develop effective preventative or therapeutic strategies.
• This case underscores the importance of careful diagnosis and consideration of potential recurrence in transplant candidates with MCD.
