Modalities of Renal Replacement Therapy in Pediatric Acute Kidney Injury (EPURE)

• Current incidence [ Time Frame: at day 60 +/- 3 ] [ Designated as safety issue: No ]
  Current incidence of the use of extra renal replacement therapy in pediatric acute renal failure
• etiologies [ Time Frame: at day 0 ] [ Designated as safety issue: No ]
  Acute kidney injury etiologies leading to extra renal replacement therapy
• Risk factors of mortality and non recovery of the renal function [ Time Frame: at day 60 ] [ Designated as safety issue: No ]

  Risk factors of mortality and non recovery of the renal function at day 60 in child acute kidney injur treated by extra renal replacement therapy (including, among others, the choice of dialysis modality (i.e. Intermittent Hemodialysis, Continuous Renal Replacement Therapies, and Peritoneal Dialysis), the indications for and timing of dialysis intervention, and the dose of dialysis).

Limited prospective data is available to compare morbidity and mortality between renal replacement modalities in pediatric acute renal failure.

In the absence of clear standard of care, the choice of the extra renal replacement therapy modality is subject to clinical judgement, practical aspects, and costs.

This study will supply important data about usual modalities of pediatric acute extra renal replacement therapy and their impact on patient outcome and renal recovery. An obvious next step will be to conduct a randomized controlled trial comparing the different strategies.

In children, there are limited data on extra renal replacement therapy. Pediatric studies are often retrospective, or often limited to specific disease processes or specific extra renal therapy. The lack of large studies including different usual modalities in pediatrics limits any formal recommendation on use in relation to patient outcomes, including renal recovery and mortality. Some of the issues that need consideration are the choice of dialysis modality (including Intermittent Hemodialysis, Continuous Renal Replacement Therapies, and Peritoneal Dialysis), the indications for and timing of dialysis intervention, the dose of dialysis and their effects on outcomes from acute kidney injury in children.

This study will supply important data about pediatric acute extra renal replacement therapy, including the epidemiology of pediatric acute kidney injury leading to extra renal replacement therapy, the variety of the treatment modalities, and their effects on the course of the disease.
