Abstract
Sepsis is a leading cause of morbidity and mortality worldwide. Dysregulated immune response to infection is a hallmark of sepsis, leading to life-threatening organ dysfunction or even death. Advancing knowledge of the complex pathophysiological mechanisms has been a strong impetus for the development of therapeutic strategies aimed at rebalancing the immune response by modulating the excess of both pro- and anti-inflammatory mediators. There is a wealth of preclinical data suggesting clinical benefits of various extracorporeal techniques in an attempt to modulate the exaggerated host inflammatory response. However, the evidence base is often weak. Owing to both an advancing comprehension of the pathophysiology and the increased quality of clinical trials, progress has been made in establishing extracorporeal therapies as part of the general therapeutic canon in sepsis. We aim for a comprehensive overview of the technical aspects and clinical applications in the context of the latest evidence concerning these techniques.

Abstract
Background Blood purification through the removal of plasma solutes by adsorption to beads of charcoal or resins contained in a cartridge (hemoperfusion) has a long and imperfect history. Developments in production and coating technology, however, have recently increased the biocompatibility of sorbents and have spurred renewed interest in hemoperfusion. Methods We performed a narrative assessment of the literature with focus on the technology, characteristics, and principles of hemoperfusion. We assessed publications in ex vivo, animal, and human studies. We synthesized such literature in a technical and state-of-the-art summary. Results Early hemoperfusion studies were hampered by bioincompatibility. Recent technology, however, has improved its safety. Hemoperfusion has been used with positive effects in chronic dialysis and chronic liver disease. It has also demonstrated extraction of a variety of toxins and drugs during episodes of overdose. Trials with endotoxin binding polymyxin B have shown mixed results in septic shock and are under active investigation. The role of non-selective hemoperfusion in sepsis or inflammation remains. Although new technologies have made sorbents more biocompatible, the research agenda in the field remains vast. Conclusion New sorbents markedly differ from those used in the past because of greater biocompatibility and safety. Initial studies of novel sorbent-based hemoperfusion show some promise in specific chronic conditions and some acute states. Systematic studies of novel sorbent-based hemoperfusion are now both necessary and justified.

The Potential Role of Extracorporeal Cytokine Removal in Hemodynamic Stabilization in Hyperinflammatory Shock. Biomedicines 2021; 9:biomedicines9070768. [PMID: 34356830 PMCID: PMC8301410 DOI: 10.3390/biomedicines9070768] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Revised: 06/26/2021] [Accepted: 06/27/2021] [Indexed: 02/06/2023] Open
Abstract
Hemodynamic instability due to dysregulated host response is a life-threatening condition requiring vasopressors and vital organ support. Hemoadsorption with Cytosorb has proven to be effective in reducing cytokines and possibly in attenuating the devastating effects of the cytokine storm originating from the immune over-response to the initial insult. We reviewed the PubMed database to assess evidence of the impact of Cytosorb on norepinephrine needs in the critically ill. We further analyzed those studies including data on control cohorts in a comparative pooled analysis, defining a treatment effect as the standardized mean differences in relative reductions in vasopressor dosage at 24 h. The literature search returned 33 eligible studies. We found evidence of a significant reduction in norepinephrine requirement after treatment: median before, 0.55 (IQR: 0.39-0.90); after, 0.09 (0.00-0.25) μg/kg/min, p < 0.001. The pooled effect size at 24 h was large, though characterized by high heterogeneity. In light of the importance of a quick resolution of hemodynamic instability in the critically ill, further research is encouraged to enrich knowledge on the potentials of the therapy.

Artif Organs 2021; 45:1097-1103.

Abstract
CytoSorb is a promising tool to treat severe inflammatory status with multiple mechanisms in the acute care setting. Its effect on drugs is, however, poorly documented in vivo, although removal of small molecules might translate into decreased blood levels of life-saving medications. The aim of this study was to assess the impact of CytoSorb on vancomycin and bivalirudin clearance in a large population of critically ill patients. We performed a single-center analysis of CytoSorb treatments performed between January 2018 and March 2019 in critically ill patients admitted to our intensive care unit. A total of 109 CytoSorb treatments were performed in 89 patients. A decrease in lactate dehydrogenase (P = .007), troponin T (P = .022), and creatine phosphokinase (P = .013) was reported during treatment. Vancomycin dose required significant adjustments during treatment (P < .001), but no significant change was necessary after the first 3 days. Similarly, the requirements of bivalirudin significantly changed over days (P < .001), but no dose adjustment was needed after the first 3 days of treatment. No differences in terms of vancomycin and bivalirudin dose need was observed between patients on extracorporeal membrane oxygenation and those who were not (P = .6 and P = .6, respectively), between patients with and without continuous veno-venous hemofiltration (P = .9 and P = .9, respectively), and between CytoSorb responders or not (P = .4 and P = .7, respectively). CytoSorb is effective in mitigating the systemic inflammatory response and safe with respect to vancomycin and bivalirudin administration. These preliminary data further support the use of CytoSorb as adjunct therapy in critically ill patients.

Continuous renal replacement therapy with the addition of CytoSorb cartridge in critically ill patients with COVID-19 plus acute kidney injury: A case-series. Artif Organs 2020; 45:E101-E112. [PMID: 33190288 PMCID: PMC7753655 DOI: 10.1111/aor.13864] [Citation(s) in RCA: 45] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 10/10/2020] [Accepted: 11/08/2020] [Indexed: 01/08/2023]
Abstract
Our aim was to investigate continuous renal replacement therapy (CRRT) with CytoSorb cartridge for patients with life-threatening COVID-19 plus acute kidney injury (AKI), sepsis, acute respiratory distress syndrome (ARDS), and cytokine release syndrome (CRS). Of 492 COVID-19 patients admitted to our intensive care unit (ICU), 50 had AKI necessitating CRRT (10.16%) and were enrolled in the study. Upon ICU admission, all had AKI, ARDS, septic shock, and CRS. In addition to CRRT with CytoSorb, all received ARDS-net ventilation, prone positioning, plus empiric ribavirin, interferon beta-1b, antibiotics, hydrocortisone, and prophylactic anticoagulation. We retrospectively analyzed inflammatory biomarkers, oxygenation, organ function, duration of mechanical ventilation, ICU length-of-stay, and mortality on day-28 post-ICU admission. Patients were 49.64 ± 8.90 years old (78% male) with body mass index of 26.70 ± 2.76 kg/m2 . On ICU admission, mean Acute Physiology and Chronic Health Evaluation (APACHE) II was 22.52 ± 1.1. Sequential Organ Function Assessment (SOFA) score was 9.36 ± 2.068 and the ratio of partial arterial pressure of oxygen to fractional inspired concentration of oxygen (PaO2 /FiO2 ) was 117.46 ± 36.92. Duration of mechanical ventilation was 17.38 ± 7.39 days, ICU length-of-stay was 20.70 ± 8.83 days, and mortality 28 days post-ICU admission was 30%. Nonsurvivors had higher levels of inflammatory biomarkers, and more unresolved shock, ARDS, AKI, and pulmonary emboli (8% vs. 4%, P < .05) compared to survivors. After 2 ± 1 CRRT sessions with CytoSorb, survivors had decreased SOFA scores, lactate dehydrogenase, ferritin, D-dimers, C-reactive protein, and interleukin-6; and increased PaO2 /FiO2 ratios, and lymphocyte counts (all P < .05). Receiver-operator-curve analysis showed that posttherapy values of interleukin-6 (cutoff point >620 pg/mL) predicted in-hospital mortality for critically ill COVID-19 patients (area-under-the-curve: 0.87, 95% CI: 0.81-0.93; P = .001). No side effects of therapy were recorded. In this retrospective case-series, CRRT with the CytoSorb cartridge provided a safe rescue therapy in life-threatening COVID-19 with associated AKI, ARDS, sepsis, and hyperinflammation.
