Abstract

Insights

Anti-T lymphocyte globulin (ATLG) induction in kidney transplants shows benefits for high-risk patients but increases infection and antibody risks. For low-moderate risk patients, induction therapy

Area of Science:

  • Nephrology
  • Immunology
  • Transplantation Medicine

Background:

  • Kidney transplantation requires effective immunosuppression to prevent rejection.
  • Induction therapy is a common strategy to manage immunosuppression post-transplant.

Purpose of the Study:

  • To compare the efficacy and safety of different induction treatments in kidney transplant recipients.
  • To evaluate outcomes based on induction therapy type: no induction, Anti-T lymphocyte globulin (ATLG), and Basiliximab.

Main Methods:

  • A retrospective study of 2564 kidney transplant recipients across 15 centers.
  • Patients were grouped based on induction therapy: None (n=222), ATLG (n=1794), Basiliximab (n=548).
  • Outcomes were assessed at 1 month, 1-6 months, and 6-12 months post-transplant, with propensity score matching (PSM) applied.

Main Results:

  • Before PSM, ATLG group showed higher rates of donor-specific antibodies (DSA), cytomegalovirus (CMV) infection, general infections, and delayed graft function (DGF).
  • After PSM, rejection rates (only in the first month), graft/patient loss, and BKV incidence were comparable between ATLG and Basiliximab groups.
  • Elevated infection, CMV, and DSA rates persisted in the ATLG group; outcomes for no induction and Basiliximab groups were similar.

Conclusions:

  • ATLG demonstrates clinical benefits in high immunological risk patients, despite increased infection and DSA risks.
  • The necessity and efficacy of induction therapy in low-to-moderate immunological risk kidney transplant recipients remain debatable.
  • Basiliximab appears to be a safer alternative with comparable outcomes to no induction in certain patient populations.

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...

Kidney Transplant III: Nursing Management

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
