Adaptive Blood Purification for the Treatment of Patients With Septic Shock

Официальное название

Adaptive Blood Purification for the Treatment of Patients With Septic Shock: a Multicenter, Open-label, Randomized, Parallel Controlled Study

Обзор

There is a lack of evidence in the efficacy of extracorporeal blood purification (EBP) to reduce the mortality rate in septic shock. We have designed the EABPSS (Efficacy of Adaptive Blood Purification for Septic Shock) study to confirm whether adaptive blood purification (ABP) intervention could confer a clinical benefit. In this multicenter, open-label, randomized controlled trial, We are recruiting a total of 276 patients with septic shock. Eligible patients who provide informed consent will be randomly assigned in a 1:1 ratio to either the control group or the intervention group. Patients in the control group will receive standard care according to the Surviving Sepsis Guidelines. Patients in the intervention group will receive two 6-hour sessions of ABP treatment within 24 hours of enrollment, based on standard care. ABP is a novel, adaptive EBP strategy proposed by our research team, specifically, for patients with septic shock do not require renal replacement therapy (RRT), plasma filtration-adsorption (PFAD) will be used alone, and for patients with septic shock and acute kidney injury meeting RRT indications, a combination of PFAD-RRT will be employed. The primary endpoint of this study is all-cause mortality at 90 days after enrollment. Secondary endpoints of the study include the declining proportion of serum cytokines such as TNF-α, IL-4, IL-6, IL-8, IL-10, and HMGB1 within 24 hours after enrollment. Additionally, the study will evaluate the improvement of Sequential Organ Failure Assessment score on day 7 post-enrollment, as well as the 30-day mortality rate.

• Другое Adaptive Blood Purification (ABP)
  Patients in the intervention group, based on standard treatment, received two 6-hour adaptive blood purification (ABP) treatments within 24 hours after enrollment, that is, patients did not indicate renal replacement therapy (RRT), only coupled plasma filtration-adsorption (PFAD) therapy is used to adsorb inflammatory factors; for patients with acute kidney injury (AKI) and meeting RRT indications, PFAD-RRT treatment is used.
