Long-term renal allograft function on a tacrolimus-based, pred-free maintenance immunosuppression comparing sirolimus...

Area of Science:

• Nephrology
• Immunology
• Transplantation

Background:

• Steroid-free immunosuppression is crucial for long-term kidney transplant success.
• Optimal combinations for maintenance immunosuppression remain under investigation.

Purpose of the Study:

• To compare the efficacy of two tacrolimus-based, prednisone-free immunosuppressive protocols.
• Evaluate the impact on renal allograft survival and long-term kidney transplant function.

Main Methods:

• Prospective randomized study comparing Tacrolimus/Mycophenolate Mofetil (MMF) vs. Tacrolimus/Sirolimus (SRL).
• Patients received IL2-RA and methylprednisolone induction therapy.
• Follow-up included patient survival, graft survival, acute rejection, and glomerular filtration rate (GFR) over 3 years.

Main Results:

• Significantly better cumulative graft survival in the Tac/MMF group (1 loss) compared to Tac/SRL (6 losses) (p=0.04).
• Consistently better glomerular filtration rate (GFR) in the Tac/MMF group throughout the follow-up period.
• A flatter slope of GFR decline per month observed with Tac/MMF.

Conclusions:

• Tacrolimus/Mycophenolate Mofetil (MMF) shows superior renal allograft survival and function compared to Tacrolimus/Sirolimus (SRL).
• This steroid-free combination offers improved long-term outcomes for kidney transplant recipients.
