Delayed graft function and its management in children

Area of Science:

• Nephrology
• Transplantation Immunology
• Surgical Research

Background:

• Delayed graft function (DGF) is a common complication following renal transplantation, defined by the need for dialysis within seven days post-transplant.
• Ischaemia/reperfusion (I/R) injury, encompassing microvascular inflammation, cell death, and apoptosis, is a primary mechanism underlying DGF.
• Several clinical factors, including donor characteristics (age, creatinine, cardiovascular stability), prolonged cold ischaemia time, and recipient BMI, are associated with an increased risk of DGF.

Purpose of the Study:

• To review the definition, underlying mechanisms, risk factors, and management strategies for DGF in renal transplantation.
• To discuss the impact of DGF on long-term graft function and the current approaches to its prevention and treatment.
• To highlight ongoing clinical trials evaluating novel pharmacologic strategies for I/R injury.

Main Methods:

• Literature review of studies defining DGF and its associated risk factors.
• Analysis of mechanisms including ischaemia/reperfusion injury and regenerative processes.
• Overview of current and emerging clinical and pharmacologic management strategies.

Main Results:

• DGF is linked to donor factors, recipient factors, and procurement/transplantation variables.
• Predictive formulas exist to assess DGF risk based on specific parameters.
• The long-term impact of DGF on graft function remains debated due to variations in organ donation types.

Conclusions:

• DGF is a multifactorial complication of renal transplantation, primarily driven by I/R injury.
• Management strategies involve mitigating individual risk factors and exploring targeted pharmacologic interventions.
• Further research and clinical trials are essential to optimize DGF prevention and treatment, potentially improving long-term transplant outcomes.
