Esmolol in Sepsis Management:Evaluating Immunomodulatory Effects and Impact on Patient Outcomes

April 24, 2024 updated by: Lin Chen

Investigating the Immunomodulatory Effects of Esmolol in Sepsis Management and Its Impact on Patient Outcomes

Evaluate the effectiveness of esmolol, a selective β1-adrenergic receptor blocker, in modulating immune responses and improving patient outcomes in sepsis.

Study Overview

Detailed Description

The research aimed to investigate the immunomodulatory effects of Esmolol in sepsis treatment. A comprehensive study was conducted, incorporating both direct experimental assays and data extraction from Electronic Health Records (EHR) to evaluate physiological and immunological responses in septic patients. Specifically, Norepinephrine (NE) levels were measured, and CD4+/CD8+ T cells were quantified to assess changes influenced by Esmolol administration. Additionally, cytokine profiles, Procalcitonin (PCT) levels, complete blood counts (CBC), and routine biochemical functions were monitored through data retrieved from EHR systems, providing a broad perspective on patient health and response to treatment. This multifaceted approach aimed to determine how Esmolol affects key immune parameters and overall patient outcomes, addressing both the direct and systemic impacts of this treatment on septic patients.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: standard care plus esmolol
Patients in this group were administered Esmolol, a beta-1 selective adrenergic blocker, alongside the standard sepsis care protocols. The dosage of Esmolol was adjusted to maintain heart rate within predefined targets. Additionally, daily electrocardiogram (ECG) monitoring was conducted to assess changes in the QT interval, a critical measure given the potential cardiac effects of beta-blockers. This group aimed to explore not only the immunomodulatory effects of Esmolol but also its safety profile in terms of cardiac function in septic patients.
The primary intervention is the administration of Esmolol. Esmolol was specifically used to evaluate its immunomodulatory effects in patients with sepsis in the study. The dosage was tailored to achieve optimal heart rate control, an integral part of the therapeutic strategy aiming to mitigate the hyperadrenergic state often seen in sepsis. Alongside Esmolol, daily electrocardiogram (ECG) monitoring was incorporated to observe any changes in the QT interval, ensuring cardiac safety due to the known potential cardiac effects of beta-blockers.
No Intervention: standard care
Patients in this cohort received the standard of care for sepsis without any additional intervention. This treatment included antibiotics, fluids, and other supportive therapies as dictated by current clinical guidelines for sepsis management.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Impact of Esmolol on Survival Rates
Time Frame: Survival rates will be monitored from the time of randomization until the end of the study period or until patient death, whichever comes first, up to 28 days post-randomization.
The primary outcome measure will be the comparison of survival rates between the treatment and control groups. A logistic regression analysis will be employed to evaluate the effect of Esmolol on survival rates and clinical outcomes, adjusting for potential confounders. Additionally, Kaplan-Meier survival curves will be generated for each group, and a Log-rank test will be used to compare the differences in survival rates over the study period.
Survival rates will be monitored from the time of randomization until the end of the study period or until patient death, whichever comes first, up to 28 days post-randomization.
Improvement in Organ Function and Inflammatory Markers
Time Frame: Organ function and inflammatory markers will be measured at baseline, then regularly throughout the patient's stay in the ICU, up to a maximum of 28 days.
As a secondary outcome, the study will assess the effect of Esmolol on organ function and systemic inflammation. This will be evaluated using a composite of changes in organ function scores (such as SOFA - Sequential Organ Failure Assessment score) and levels of inflammatory markers (such as C-reactive protein and IL-6). The analysis will determine if Esmolol correlates with an improvement in these clinical parameters, suggesting a protective or restorative effect on organ function.
Organ function and inflammatory markers will be measured at baseline, then regularly throughout the patient's stay in the ICU, up to a maximum of 28 days.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Length of Intensive Care Unit (ICU) Stay
Time Frame: From the date of ICU admission until the date of ICU discharge, assessed up to 90 days.
The duration of ICU stay will be measured to determine if Esmolol administration correlates with a shorter ICU admission period. This measure can reflect the overall impact of the drug on the severity and progression of sepsis, potentially indicating more rapid patient stabilization and recovery.
From the date of ICU admission until the date of ICU discharge, assessed up to 90 days.
Reduction in Inflammatory Markers
Time Frame: Baseline and then daily measurements in ICU up to 28 days.
The study will evaluate the effect of Esmolol on systemic inflammation by measuring changes in inflammatory markers such as C-reactive protein (CRP) and interleukin-6 (IL-6) levels. A decrease in these markers could indicate a beneficial anti-inflammatory effect of the drug.
Baseline and then daily measurements in ICU up to 28 days.
