Insights

Delayed graft function (DGF) in kidney transplants from donation after cardiac death (DCD) donors is influenced by the cause of brain death, donor creatinine, and recipient dialysis time. DGF did not impact patient or graft survival in this study.

Area of Science:

  • Nephrology
  • Transplantation immunology
  • Critical care medicine

Background:

  • Donation after cardiac death (DCD) kidney transplantation is a growing source of organs.
  • Delayed graft function (DGF) is a common complication in DCD kidney transplants.
  • Understanding DGF risk factors is crucial for optimizing outcomes.

Purpose of the Study:

  • To identify risk factors associated with DGF in DCD kidney transplantation.
  • To assess the impact of DGF on patient and graft survival after DCD kidney transplantation.

Main Methods:

  • Retrospective study of 48 DCD kidney transplantations.
  • Classification of recipients into immediate graft function (IGF) and DGF groups.
  • Analysis of pre-transplant, donor, and ischemia time variables.

Main Results:

  • DGF occurred in 37.5% of DCD kidney transplants.
  • DGF did not significantly affect patient or graft survival (P=0.098 and P=0.447, respectively).
  • Independent risk factors for DGF included cerebral hemorrhage as cause of brain death (OR=39.652), donor creatinine ≥177 μmol/L (OR=57.148), and recipient dialysis time ≥12 months (OR=15.060).

Conclusions:

  • Cerebral hemorrhage, high donor creatinine, and prolonged recipient dialysis are independent risk factors for DGF in DCD kidney transplantation.
  • DGF occurrence did not adversely impact long-term transplant outcomes in this cohort.
  • Targeting these risk factors may help mitigate DGF incidence and improve DCD kidney transplant success.

Kidney Transplant I: Introduction01:28

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...

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...
Chronic Kidney Disease I: Introduction01:25

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Acute Kidney Injury III: Clinical Manifestations

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
