AI Article Synopsis

  • Early recovery in septic shock patients improves their overall prognosis, and the study explored whether Continuous Renal Replacement Therapy (CRRT) using polymyxin B (PMX-DHP) can stabilize their hemodynamics.
  • 66 septic shock patients underwent PMX-DHP, with some receiving additional continuous hemodiafiltration (CHDF), and measurements of inflammatory cytokines (IL-6, IL-1ra, PAI-1) were taken before and after treatment.
  • Results showed that PMX-DHP significantly increased Mean Arterial Pressure (MAP) and reduced cytokine levels, indicating that CRRT may be an effective strategy to improve outcomes in septic shock by modulating cytokine activity.

Article Abstract

Background: Early recovery from shock improves prognosis in septic shock patients. We determined whether cytokine modulation by Continuous Renal Replacement Therapy (CRRT) following acute care surgery resulted in stable hemodynamics in them. To investigate our hypothesis, we measured proinflammatory cytokines IL-6, IL-1ra and the coagulation cascade activator plasminogen activator inhibitor-1 (PAI-1) following CRRT with polymyxin B immobilized fiber (PMX-DHP) which has been utilized as an adjuvant treatment option for patients with severe septic shock.

Methods: 66 septic shock patients requiring 2 h direct hemoperfusion therapy PMX-DHP were included. 36 patients of them also received continuous hemodiafiltration (CHDF) after performing PMX-DHP. Circulatory dynamics and levels of inflammatory mediators, namely IL-6, IL-1ra, and PAI-1 were assessed before, immediately after, and 24 h initiation of PMX-DHP.

Results: Mean Arterial Pressure (MAP) rose intentionally by PMX-DHP just after enforcement 24 h later ( < 0.01). Levels of IL-6, IL-1ra, and PAI-1 significantly decreased after PMX-DHP ( < 0.05) and this trend was observed up to 24 h post initiation of PMX-DHP ( < 0.05). IL-6 modulation by PMX-DHP was enhanced with using CHDF and there was a significant correlation between IL-6 and MAP ( < 0.0001). In addition, levels of Il-6 and PAI-1 showed a significant correlation.

Conclusion: Our data showed employing CRRT as cytokine modulators could be an additional therapeutic strategy to improve septic shock outcomes the crucial role of IL-6 signaling in endothelial dysfunction.

Based on the fact that beta-lactam antibiotics demonstrate time-dependent killing, different dosing strategies have been implemented to increase the time that free (f) (unbound) antibiotic concentrations remain above the Minimal Inhibitory Concentration (MIC), including prolonged and continuous infusion. Multiple studies have been performed that compared continuous with traditional intermittent infusion to improve outcomes in patients with severe sepsis and/or septic shock. These studies have yielded inconsistent results for patients as measured by clinical response to treatment and mortality due to heterogeneity of included patients, pathogens, dosing strategies and the absence of Therapeutic Drug Monitoring (TDM).

Bacteremia is a serious clinical condition in which pathogenic bacteria enter the bloodstream, putting patients at risk of septic shock and necessitating antibiotic treatment. Choosing the most effective antibiotic is crucial not only for resolving the infection but also for minimizing side effects, such as dysbiosis in the healthy microbiome and reducing the selection pressure for antibiotic resistance. This requires prompt identification of the pathogen and antibiotic susceptibility testing, yet these processes are inherently slow in standard clinical microbiology labs due to reliance on growth-based assays.

Background: Multidrug-resistant Klebsiella pneumoniae (MDR-KP) infections pose a significant global healthcare challenge, particularly due to the high mortality risk associated with septic shock. This study aimed to develop and validate a machine learning-based model to predict the risk of MDR-KP-associated septic shock, enabling early risk stratification and targeted interventions.

Methods: A retrospective analysis was conducted on 1,385 patients with MDR-KP infections admitted between January 2019 and June 2024.

Introduction: One of the most prevalent healthcare-associated infections in the pediatric intensive care unit is ventilator-associated pneumonia (VAP). VAP not only results in prolonged hospital and intensive care unit (ICU) stays but also imposes higher costs on patients and the healthcare system. Therefore, it is essential to implement preventive measures.
