Lipopolysaccharide Adsorption at Septic Shock — LASSO  

Septic Shock Clinical Trial

Official title:
Lipopolysaccharide Adsorption at Septic Shock With Efferon LPS Extracorporeal Blood Adsorbers

Clinical Trial Summary

Sepsis is a global healthcare burden sepsis, it reaches 20-30 million cases annually (WHO data). Numerous studies have shown that extracorporeal hemoperfusion therapies that eliminate endotoxin and\or excess of cytokines improve treatment outcomes in patients with septic shock. The main purpose of the study is to obtain new data on the efficacy and safety of the Efferon LPS device in extracorporeal therapy in patients with abdominal sepsis complicated by septic shock.

Clinical Trial Description

Sepsis is a global healthcare burden sepsis, it reaches 20-30 million cases annually (WHO data). A two-stage trial by Rudnov et al. using one-day data from 62 centres in 29 subjects of the Russian Federation showed that one third of the patients admitted to the ICU were patients with infection, one fifth of them developed septic shock, the proportion of hospital sepsis was 46.6%, and fatal outcome occurred in 30.4% of patients with infection. Despite apparent advances in intensive care, the prognosis of patients with endotoxaemia and septic shock remains poor. Extracorporeal removal of toxic substances from the bloodstream by adsorbing them onto a porous material may provide clear clinical benefits. Extracorporeal blood adsorption method can be a good complement or substitute for the classical methods of haemofiltration and haemodialysis if the diffusion or convection of toxic substances through the membrane is not efficient enough. Since the method was first proposed by Muirhead and Reid in 1948, it has developed considerably. Endotoxin (lipopolysaccharide), one of the most potent mediators of sepsis, is found in high concentrations in about 50% of patients with septic shock. The use of extracorporeal sorption techniques that eliminate endotoxin has been shown in numerous trials to improve outcomes in patients with septic shock. Efferon LPS (Efferon JSC, Moscow, Russia) is a single-use therapeutic device for extracorporeal blood purification using direct hemoperfusion. Detoxification is carried out by selective adsorption of lipopolysaccharides (bacterial endotoxins) and non-selective removal of cytokines by internal porous structure. It is a cylindrical polycarbonate casing filled with spherical granules of LPS-selective polymeric adsorbent mesoporous beads and isotonic sodium chloride solution. The device is registered in Russia as a medical device RZN 2019/8886. ;
