Insights

Basiliximab is a cost-effective alternative to anti-thymocyte globulin (ATG) for kidney transplants using donation after circulatory death (DCD) grafts in low-risk patients. This study found similar graft outcomes and safety profiles between the two induction therapies.

Area of Science:

  • Nephrology
  • Transplantation Immunology
  • Organ Donation

Background:

  • Donation after circulatory death (DCD) kidney grafts are increasingly used due to organ shortages.
  • DCD grafts have higher rates of delayed graft function (DGF), leading to specific management protocols.
  • The French national protocol recommends hypothermic machine perfusion and anti-thymocyte globulin (ATG) for DCD kidney transplants.

Purpose of the Study:

  • To compare the efficacy and safety of basiliximab versus ATG induction therapy in low immunological risk DCD kidney transplantation.
  • To evaluate the cost-effectiveness of basiliximab as an alternative to ATG in this patient population.

Main Methods:

  • Retrospective analysis of a single-center cohort (n=158) of low-risk DCD kidney transplant recipients (2015-2023).
  • Comparison of outcomes between patients receiving ATG (pre-March 2020) and basiliximab (post-March 2020).
  • Validation of findings in an independent French multicenter cohort (n=506).

Main Results:

  • No significant differences in primary non-function, DGF rates (17% ATG vs. 12% basiliximab), rejection, one-year renal function, or graft survival.
  • ATG was associated with prolonged Epstein-Barr virus (EBV) and BK viremia without increased complications.
  • Basiliximab induction was associated with a 1.7-fold lower cost compared to ATG, with similar hospital stays.

Conclusions:

  • Basiliximab is a viable and cost-effective alternative to ATG for low-immunological-risk DCD kidney transplant recipients.
  • Current evidence does not strongly favor ATG over basiliximab for this specific patient group.
  • This finding supports a potential shift in induction therapy protocols for DCD kidney transplantation.

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...
