Approximately 10-15% of sepsis cases, or approximately one-third to half of patients with septic shock, exhibit high levels of endotoxin activity in their blood. Humans are exquisitely sensitive to endotoxin making endotoxic septic shock (ESS) particularly deadly. Today, we have an emerging class of EBP that is specific to endotoxin - targeted rapid endotoxin adsorption (TREA) - that can be used for the treatment of ESS.</p><p><strong>Summary: </strong>In septic patients, evidence for the use of hemofiltration and therapeutic plasma exchange, the two most prevalent forms of EBP, has been difficult to obtain. Additionally, broad-spectrum EBP therapies that target multiple solutes for removal have struggled to identify the right patients. There is significant clinical heterogeneity of the innate immune response across patients with sepsis. In contrast, targeted EBP therapies, which involve measuring a single solute, then choosing appropriate therapy to target its removal, allow for the specific selection of a suitable patient. Unfortunately, measuring the target can prove challenging. Endotoxin can be measured in whole blood using the endotoxin activity assay. However, owing to the size of intact endotoxin molecule, it cannot be filtered using hemofiltration membranes. Adsorption, which only requires the contact of blood or plasma with a sorbent, is therefore a suitable model to target its removal. TREA technologies include devices that specifically target endotoxin (Alteco LPS Adsorber, MATISSE adsorber, Toraymyxin 20R, Toxipak sorption column) and those for which endotoxin removal is included in a more broad-spectrum device (Efferon LPS, oXiris).</p><p><strong>Key messages: </strong>While only a small number of devices are currently available in the TREA class of EBP, there is an opportunity here to bring precision medicine to sepsis.</p>","PeriodicalId":8953,"journal":{"name":"Blood Purification","volume":" ","pages":"354-365"},"PeriodicalIF":2.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
