RandomizEd ClinicAL triaL on the Efficacy and saFety of Incremental Hemodialysis (REAL-LIFE)

Condition(s) studied

Investigational drug(s) / intervention(s)

Incremental hemodialysis: 95 patients will start renal replacement therapy (RRT) with an incremental hemodialysis (once-weekly or twice-weekly) regimen.

Conventional hemodialysis: 95 patients will start renal replacement therapy (RRT) with the standard (thrice-weekly) hemodialysis regimen.

Study summary

Background: The thrice-weekly hemodialysis (HD) regimen is widely accepted as a standard prescription. The concept of incremental dialysis has been established as a possible alternative for patients with preserved diuresis and end-stage renal failure in need of HD. The main problems related to prescription of incremental HD are an arbitrary use of infrequent regimens and the lack of clear standards for incorporating residual kidney function (RKF) in the assessment of HD dose. Several models have been proposed for prescription of incremental dialysis. The latest, the variable target model (VTM), gives more clinical weight to the RKF and allows less frequent HD treatments at lower RKF. Despite increasing evidence derived from observational studies to support the use of incremental HD, RCTs are lacking and, therefore, urgently needed.

Methods/Design:

The Department of Nephrology, Dialysis and Transplantation of the Azienda Ospedaliero Universitaria Consorziale Policlinico, Bari, Italy and the EUDIAL Working Group of the European Renal Association - European Dialysis Transplant Association (ERA-EDTA) are starting a randomized clinical trial (RCT) in incident HD patients, whose name is "REAL LIFE", by using the acronym of its whole definition: RandomizEd clinicAL triaL on the effIcacy and saFety of incremental haEmodialysis. REAL LIFE is a pragmatic, prospective, multicentre, open label RCT, investigator-initiated, comparing the intervention arm (incremental HD) with the control arm (standard 3HD/wk). The trial, originally conceived by experts at the Division of Nephrology of the Miulli General Hospital, Acquaviva delle Fonti, Italy, consists in starting the HD treatment adopting the new incremental approach guided by the VTM. The primary outcome is the survival of kidney function, with the event defined as urinary output (UO) ≤ 200 mL/day, confirmed by a further collection after 2 weeks to exclude temporary illness.

Discussion: REAL LIFE will enable the investigators to know with the highest level of scientific evidence the safety and efficacy of an incremental approach to the start of HD treatment.

Eligibility

Primary outcome measure(s)

• Number of participants whose kidney function remains >200 ml — 24 months
  The survival of kidney function is defined as a time to the event (anuria): the anuria is defined as urinary output (UO) ≤ 200 mL/day, confirmed by a further collection after 2 weeks to exclude temporary illness
