Clinical Trial Summary

The purpose of this study is : - to evaluate the hemodynamic tolerance of esmolol titrated to obtain a lowering of heart rate of 10% or 20%.

Description:

During septic shock, the consequences of treatment by a β1-blocker on inflammation and cardiovascular variability are unknown. The use of esmolol should have positive effects on inflammation and hemodynamic tolerance. These effects are probably dose-dependent. The study will enroll adult patients hospitalized in ICU, for severe septic shock requiring treatment by a vasopressor. A total of 45 patients will be included. Among these 45 patients, 15 patients will be randomized in the control group. 30 patients will be randomized to Esmolol with the objective to decrease heart rate by 10% (Group G10, n=15) or 20% (Group G20, n=15). Esmolol will be administered for 24 hours. This multicenter study will be performed in 3 investigation sites. The following parameters will be evaluated at different moments during the 28 days follow up of each patient, mainly: - Origin of sepsis, SOFA score. - Hemodynamic parameters will be continuously recorded for the 24 hours of experimental period. - Cardiovascular variability (arterial pressure and heart rate) will be recorded for 24 hours. - 3 echocardiograms at H0, H12 and H24 will be performed. - Biological parameters will be sampled at H0, H6, H12 and H24: They include standard biological parameters (Urea, Creatinin, Bilirubin,……) and specific parameters (catecholamines, vasopressin, insulin, cortisol, proinflammatory cytokines and anti-inflammatory cytokines. Dosages will be performed only at H0, H12 and H24 in order to study: - The expression of adrenergic receptors and their genetic polymorphisms on circulating immune cells. - The Th1/Th2 balance in immune cells. Each patient will be followed-up for 28 days. The variation of MAP and of cardiac output induced by esmolol should not exceed 15% of baseline values. If the variation is more important esmolol administration will be stopped and the hemodynamical tolerance will be defined as poor.

Intervention

Drug:
• Esmolol administration
Esmolol will be administered during 24 hours, beginning with a titration period to determine the minimal dose allowing to achieve the randomized heart rate reduction of 10% or 20%, as defined by randomization. Titration will be performed in sequences of increasing doses, beginning with 5 µg/kg/min as initial dose, and increasing by 5 µg/kg/min each 30 minutes until the target heart rate reduction is obtained. The maximum dose is 200 µg/kg/min. The titrated dose will be maintained for a total duration of 24 hours.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Comparison of hemodynamic parameters between 3 groups	3 groups: GC, G10 and G20.; The hemodynamic tolerance will be considered as satisfactory if the variation of MAP and cardiac output induced by esmolol does not exceed 15% of baseline (H0).	24 hours
Primary	Immunomodulatory effect	Immunomodulatory effect of esmolol will be evaluated notably by the ratio of IL6 / IL10.; The decrease of this ratio in comparison with the value at baseline (H0) will be considered as an indicator of esmolol efficacy as immunomodulator.	24 hours
Secondary	Comparison of number and severity of organ failures, between the 3 groups	3 groups will be evaluated by SOFA score.	28 days
Secondary	Comparison of autonomic nervous system activity between the 3 groups	Power spectrum analysis of heart rate variability.	24 hours
Secondary	Comparison of mortality in the 3 groups		28 days
Secondary	Comparison in the 3 groups of the correlations between the biomarkers and the hemodynamic data	The biomarkers in plasma levels: cortisol, catecholamine, proinflammatory cytokines and anti-inflammatory cytokines.	24 hours
