FURosemide Stress Test to Predict Need of Renal Replacement THERapy in Ischemic Acute Tubular Necrosis in ICU

Phase 4
Terminated
Conditions
Acute Kidney Injury
Interventions
Registration Number
NCT03731117
Lead Sponsor
Assistance Publique - Hôpitaux de Paris
Brief Summary

Ischemic acute tubular necrosis (ATN) is one of the main cause of acute kidney injury (AKI) in intensive care units (ICU). Sepsis and cardio-pulmonary bypass (CPB) are major providers. There is no validated tool to predict the evolution of AKI is ICU. Furosemide Stress Test (FST) may predict evolution of ATN-related AKI outside ICU in terms of progressive AKI, need for renal replacement therapy (RRT) or inpatient mortality with improved performance comparing to biomarkers. FST has not been validated in a prospective cohort in ICU in the settings of ischemic ATN. FURTHER aim to determine whether FST would be a useful tool to identify patients with slight to moderate AKI (KDIGO stage 1 and 2) who will evolve towards need for RRT following AKIKI (The Artificial Kidney Initiation in Kidney Injury ) delayed initiation criteria.

Detailed Description

FURTHER will enroll consecutive patients with AKI KDIGO stage 1 or 2 associated with a sepsis or following a cardiac surgery with CPB within 72h. Patients must have achieved a hemodynamic stabilization confirmed by clinical (no need for intravenous fluids, no significant variation of noradrenaline) and non-clinical (trans-thoracic echocardiography, passive leg rise or other validated tool) assessment. Included patients will receive 1 to 1.5 mg/kg of FUROSEMIDE. Urine output will be measured for 6 hours and compensated by the same volume of intravenous crystalloids. Need for RRT will be assess at 2-hour, 6-hour and daily up to day 7, following the AKIKI-study delayed initiation arm criteria. FURTHER aim to evaluate FST in a well-defined prospective cohort of ischemic ATN-related AKI as predictor of need for RRT within a week.

Primary Outcome Measures
NameTimeMethod
Need for renal replacement therapy or deathBefore day 7

Need for renal replacement therapy will be define according to the AKIKI study (Gaudry S, Hajage D, Schortgen F, Martin-Lefevre L, Pons B, Boulet E, et al. Initiation Strategies for Renal-Replacement Therapy in the Intensive Care Unit. N Engl J Med. 2016 Jul 14;375(2):122-33). Need for RRT following AKIKI delayed initiation criteria.

FST performance will be compared to the need of RRT or death.

sensitivity3 hour after FST

FST will be positive if patient is non responder : 2-hour urine output \< 200mL
