Oxiris Membrane in Sepsis and Multiple Organ Failure.

Sepsis and multiple organ failure (MOF) are characterized by multiple hemodynamic changes and imbalanced immune response of the patient. Oxiris is a highly adsorptive membrane with the ability to remove cytokines and endotoxins, as well as to perform renal replacement therapy. Here we describe the evolution from previous AN69 to the 3-in-1 Oxiris membrane, and review its characteristics and performance. In clinical practice, Oxiris showed consistent effects in mean arterial pressure recovery, a decrease in vasopressor needs, and reduction of the Sequential Organ Failure Assessment score. These results have been reproduced by several independent studies addressing both sepsis and, to a lesser extent, COVID-19 patients. In addition, more recent studies in sepsis showed improvements in MOF duration and the length of stay in the ICU, as well as some promising results regarding mortality. Finally, we review ongoing clinical trials and discuss its potential significance to clinical practice improvement and to further reinforce knowledge on the use of blood purification in sepsis and acute kidney injury.
