Cardiorenal Interactions During Treatment of Acute Decompensated Heart Failure: Diuretics Versus Ultrafiltration (CRUF)

January 9, 2012 updated by: University Hospital, Ghent
The CRUF trial is a prospective randomized monocentric trial comparing different impact of diuretics versus ultrafiltration on renal congestion, plasma refill rate, echocardiographic filling pressures, neurohormonal activation and biomarkers of Acute Kidney Injury (AKI).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: ultrafiltration group
Procedure: ultrafiltration
Ultrafiltration through double lumen catheter, via central vein (Vena jugularis interna or Vena femoralis, 11 French, 15 cm for right jugular or 20 cm for femoralis and jugularis left-position). Based on severity of fluid overload the cardiologist determines the ultrafiltration rate. 'Multifiltrate Fresenius' (extracorporeal blood volume 72ml) in SCUF (slow continuous ultrafiltration) modus with pediatric lines (54 ml extracorporeal volume in the AV-set) and a pediatric filter (Ultraflux® AV paed, blood volume 18ml). Heparin to maintain an APTT between 65 en 85 seconds during ultrafiltration.
ACTIVE_COMPARATOR: diuretics group
Drug: diuretics
Bumetanide continuous infusion to reach a prescribed negative fluid balance: dose adjustment according to the diuretic response.

Secondary Outcome Measures

Outcome Measure
Time Frame
determination of the value of Neutrophil gelatinase-associated lipocalin (NGAL) to predict AKI in acute decompensated heart failure (vs creatinine, Cystatin C,measured urinary creatinine clearance) in patients treated with diuretics vs ultrafiltration.

Combined endpoint of mortality/rehospitalisation-urgent outpatient visit due to heart failure
Time Frame: at 6 months
at 6 months
