The treatment of sepsis is an ongoing challenge for clinicians; despite the wide choice of effective antibiotics to treat infection, sepsis remains the leading cause of morbidity and mortality for patients admitted to an intensive care unit. Dysregulation of the immune response is now recognized to be a key factor in multiple organ dysfunction, yet our therapy for inflammation remains ineffective. It has been advocated for more than a decade that cytokine reduction in blood compartment could lead to a reduction in mortality in sepsis. ⋯ In addition, new experimental systems that utilize human phagocytic cells and immobilized antibodies for targeted immunomodulation have emerged. In the context of limited resources and growing expansion in the availability of technologies, a better understanding of these therapies is required before they can be properly integrated into standard clinical practice in the hope of influencing major clinical outcomes. In this article, we will provide a concise overview of selected extracorporeal modalities currently in clinical use and briefly introduce some new promising techniques for sepsis.

Red cell distribution width and outcome in patients with septic shock.
Red cell distribution width (RDW) is reflective of systemic inflammation. The objective of this study was to investigate the association between RDW (on day 1 of development of septic shock) and mortality. ⋯ Red cell distribution width on day 1 of septic shock is a robust predictor of mortality. The RDW is inexpensive and commonly measured. The RDW fared better than either APACHE II or SOFA, and the sum of RDW and APACHE II was a stronger predictor of mortality than either one alone.

Associations between the use of critical care procedures and change in functional status at discharge.
Quality improvement initiatives in intensive care units (ICUs) have increased survival rates. Changes in functional status following ICU care have been studied, but results are inconclusive because of insufficient consideration of the combinations of critical care procedures used. Using the Japanese administrative database including the Barthel Index (BI) at admission and discharge, we measured the changes in functional status among the adult patients and determined whether longer ICU stay or use of various critical care procedures was associated with functional deterioration. ⋯ Of 234 209 patients with complete BI information, 7137 (3.1%) received blood purification, 27 100 (11.7%) received ventilation, 2888 (1.2%) received blood purification and ventilation, 5613 (2.4%) received a cardiac support device, 247 (0.1%) received a cardiac support device and blood purification, 10 444 (4.5%) received a cardiac support device and ventilation, and 1110 (0.5%) received a cardiac support device, ventilation, and blood purification. Longer use of blood purification or ventilation and a longer ICU stay were associated with functional deterioration. Intensivists should be aware of the effects of critical care procedures on functional deterioration and advance the appropriate use of functional support according to each patient's condition.
