IL Ancillary Study of the Therapeutic Hypothermia After Nonshockable Cardiac Arrest Trial. (IL-HYPERION)

February 22, 2019 updated by: Centre Hospitalier Departemental Vendee

InterLeukine Ancillary Study of the Therapeutic Hypothermia After Nonshockable Cardiac Arrest Trial.

Cardiac arrest is at present a major cause of mortality as well as a cause of disability for the surviving victims.In Europe, every year counts as 300,000 cardiac arrests responsible for 250,000 deaths. Thus, less than 20 % of patients discharged home with impaired quality of life associated with symptoms of tiredness, stress, anxiety. The prognosis is related to the initial cardiac rhythm present during the initiation of resuscitation. Recent progress in the improvement of mortality and neurological outcome has been achieved over the last decade thanks to the systematic implementation of a period of targeted temperature control between 32 and 34 ° C in patients who benefited from the realization of at least one electrical external shock.

There are theoretical and clinical arguments to think that achieving the same way a period of targeted temperature control between 32 and 34 ° C in patients treated for cardiac arrest with a non- shockable rhythm on arrival can also benefit from this procedure. However other arguments are against this hypothesis including an increase in the risk of infection , worsening of the patient's hemodynamic status with no benefit to him. To answer this question, we conduce a randomized multicenter study testing the potential improvement of neurological outcome through this procedure targeted temperature control between 32.5 and 33.5 ° C in these patients.

IL Ancillary Study of HYPERION Trial will determine impact on inflammatory biomarkers of two temperature target for targeted temperature management (33°C or 37°C) after cardiac arrest in non-shockable rhythm.

  • Low-flow time >60 min (time from initiation of external cardiac massage to return of spontaneous circulation).
  • Major hemodynamic instability (defined as a continuous epinephrine or norepinephrine infusion at a flow rate >1 μg/Kg/min)
  • Time from cardiac arrest to study inclusion >300 min
  • Moribund patient
  • Child C cirrhosis of the liver

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Targeted controlled temperature between 32.5 and 33.5°C
Patients will be placed in targeted temperature control between 32.5 and 33.5 ° C for 24 hours and then slowly rewarmed for targeted temperature control between 36.5 and 37.5 ° C for 24 hours.
There is 6 dosage of inflammatory biomarker per patient included: H0, H12, H24, H36, H48 and H72 during targeted temperature management between 33°C and 37°C.
Placebo Comparator: Targeted controlled temperature between 36.5 and 37.5°C
Patients will be placed in targeted temperature control between 36.5 and 37.5 ° C for 48 hours.
There is 6 dosage of inflammatory biomarker per patient included: H0, H12, H24, H36, H48 and H72 during targeted temperature management at 37°C.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Interleukine 6 level between H0 and H72
Time Frame: 72 hours
Comparing the production of interleukin 6 (inflammatory cytokine) during targeted temperature management at 33 or 37 °C after cardiac arrest in non-shockable rhythm when help arrived and before the injection of adrenaline. The analysis of the primary endpoint will be performed using an analysis of covariance, taking into account the basal value of interleukine 6. Necessary data will be pre-processed.
