The ICU is a complex environment that could benefit from ways to simplify therapy delivery

Versatile innovation

The Oxiris filterset can be used to deliver haemoperfusion to reduce elevated levels of inflammatory mediators/endotoxins and/or to deliver any CRRT modality (SCUF, CVVH, CVVHD, CVVHDF) to provide uremic toxin removal and support fluid management.5 Note: CVVH, Continuous Veno-Venous Haemofiltration; CVVHD, Continuous Veno-Venous HaemoDialysis; CVVHDF, Continuous Veno-Venous Haemodiafiltration; SCUF, Slow Continuous UltraFiltration 

Inflammatory mediator removal

A prospective, multicenter, observational study reported a significant decrease from baseline in serum IL-6 levels in patients with COVID-19 treated with the Oxiris filterset.2

Endotoxin removal

A randomised, crossover study reported significantly greater changes from baseline in endotoxin level with the Oxiris filterset, compared to the AN69ST filterset in patients with septic-shock-associated AKI.3 

Versatile simplification 

The Oxiris filterset is designed to simplify blood purification therapy delivery for patients requiring both cytokine/endotoxin removal and CRRT, which may free up nursing time. The Oxiris filterset is part of a pre-connected set for simplicity. The closed system includes a filter membrane pre-connected to the colour-coded tubing, minimising setup steps and reducing potential for touch contamination.5,16

The Oxiris filterset can play a role in the management of patients with COVID-19

In a prospective observational pilot study of COVID-19 patients (n=37) admitted to an ICU in Italy between February and April 2020, patients were treated with extracorporeal blood purification (EBP) using the Oxiris filterset for immunomodulation and/or support to renal function during AKI.2 

Results suggest that early initiation of EBP during COVID-19 may be associated with greater benefits.

 

*IL-6 reduction was statistically significant over the first 72 hours of treatment (p<0.001), and for each time period (24h, 48h, 72h) compared to baseline (p=0.001). p<0.016 considered for statistical significance.

 †Sequential Organ Failure Assessment.

 ‡SOFA score reduction was statistically significant over the first 72 hours of treatment (p=0.002), and at 48h vs baseline (p=0.001) and 72h vs baseline (p=0.002). p<0.016 considered for statistical significance.

 §Due to the observational design of this study (single arm without active control group), it was not possible to determine whether a causal relationship exists between EBP with Oxiris and improvement in patient outcomes (organ function or mortality). Given the small number of patients studied, it was not possible to identify any parameter values or illness stage that might indicate a threshold or cutoff for the best time to initiate EBP.

 ¶Acute Physiological and Chronic Health Evaluation (APACHE) is a scoring system for disease severity that uses actual clinical data obtained on the first day of ICU admission to estimate the risk of short-term mortality as well as predict the length of ICU stay.

Oxiris is the ONLY blood purification filterset to effectively remove inflammatory mediators, endotoxin, fluid and uremic toxins SIMULTANEOUSLY.1-5

Its unique membrane technology provides a 3-fold mode of action.17-19

  • Heparin coating: pre-coating the membrane with heparin reduces the thrombogenicity of the polyethyleneimine (PEI) coating
  • PEI surface treatment: adsorbs endotoxin
  • AN69 base membrane: adsorbs cytokines and toxins while providing continuous renal support. Cytokine adsorption occurs throughout the entire membrane thickness

Endotoxin and cytokine removal with the Oxiris filterset in vivo

A retrospective observational case series of patients with sepsis treated with CRRT using the Oxiris filterset reported decreases from baseline in levels of pro- and anti-inflammatory cytokines (IL-6, IL-10) and other markers of infection (procalcitonin levels and endotoxin activity).1 The change from baseline in immunologic parameters to the end of treatment with the Oxiris filterset (74 ± 36 hours) is a decrease of 74% for IL-10, 75% for IL-6 and 73% for procalcitonin.a

aChange from baseline to the end of treatment (74 ± 36 hours) in endotoxin activity (0.74 ± 0.15 to 0.58 ± 0.18), IL-6 (506 ± 400 to 126 ± 92 pg/mL, P < 0.001), IL-10 (106 ± 57 to 28 ± 17 pg/mL, P < 0.05), and procalcitonin (30 ± 36 to 8 ± 9 ng/mL, P < 0.05).

The COVID-19 pandemic

  • Systemic inflammation in patients with COVID-19 can lead to multi-organ failure, including AKI.22,23
  • Blood purification techniques have been shown to remove cytokines, endotoxin and circulating viral particles in patients with COVID-19.24
  • Blood purification is the only therapy that may effectively remove inflammatory mediators, damage-associated molecular patterns (DAMPs) and/or pathogen-associated molecular patterns (PAMPs, e.g., endotoxin),2 which may help mitigate progression to multi-organ failure.1,2,9,11,20,21,25  

Potential targets for COVID-19 therapies include the removal of cytokines26

Stages of the SARS-CoV-2 life cycle offer potential treatment targets. Potential targets for COVID-19 therapies include anti-inflammatory therapies,27 prevention of membrane fusion and viral cell entry,28 removal of cytokines or prevention of cytokine receptor activation26,28,29 and prevention of RNA translation.28,30-33
