Efferon LPS Hemoadsorption in Patients With Acute Pancreatitis

Официальное название

Lipopolysaccharide Adsorption (Efferon LPS) in Patients With Acute Pancreatitis

Обзор

The goal of the study is to evaluate the safety and efficacy of multimodal (cytokine and lipopolysaccharide) hemoperfusion using the Efferon® LPS device in combination with hemofiltration (HF) / hemodiafiltration (HDF), with the goal of reducing the severity of organ dysfunction (measured by SOFA score) in patients with acute pancreatitis. Participants will be assigned to two groups for comparison: a control group receiving baseline therapy with HF/HDF, and a treatment group receiving baseline therapy in combination with HF/HDF and Efferon® LPS hemoadsorption.The therapy will be initiated within the first 24 hours after ICU admission and within 8 hours after patient enrollment.

Подробное описание

Acute pancreatitis remains a life-threatening disorder with a considerable risk of unfavorable outcomes. In patients with severe acute pancreatitis (SAP), hospital mortality ranges from 16% to 20% and may rise to 60% in cases complicated by multiple organ dysfunction (MOD). Progressive MOD, arising from systemic inflammatory response syndrome (SIRS), represents the principal cause of early death. Recently, extracorporeal blood purification techniques, including hemoperfusion, have emerged as valuable adjuncts to intensive care, providing opportunities to correct derangements in homeostasis.

In recent years, extracorporeal blood purification methods, including hemoperfusion, have become one of the components of intensive care, allowing for correction of homeostatic parameters.

The Efferon® LPS device was originally developed for use in sepsis, utilizing its ability to effectively target both primary and secondary inflammatory mediators. However, this approach also has significant potential for the treatment of acute pancreatitis, a condition characterized by a similarly complex inflammatory response.

The goal of the study is to evaluate the safety and efficacy of multimodal (cytokine and lipopolysaccharide) hemoperfusion using the Efferon® LPS device in combination with hemofiltration/hemodiafiltration, with the goal of reducing the severity of organ dysfunction in patients with acute pancreatitis.

Вмешательства

• Устройство Efferon LPS
  Efferon LPS, a medical device, which is a single-use cartridge filled with a polymeric adsorbent that selectively adsorbs endotoxin via surface-immobilized ligand and excessive cytokines via its intrinsic porosity. Efferon LPS will be administered in combination with either hemofiltration (HF) or hemodiafiltration (HDF). The choice between HF and HDF will be made by the investigator, based on the individual clinical situation.The therapy will be initiated within the first 24 hours after ICU adm
