Research Abstract

Severe sepsis can result in multiple organ dysfunction syndrome (MODS), a potentially life-threatening condition. In the process, high mobility group box 1 protein (HMGB1) was found to be a key mediator of exacerbating organ injury. Although sepsis is the common cause of mortality in intensive care units, few therapies have established sufficient evidence. In the present study, we evaluated the effects of blood purification therapy targeting at elimination of HMGB1 in a LPS-induced systemic inflammatory rat model. As a result, we showed that blood purification therapy (hemodiafiltration, leukocytapheresis) reduced serum HMGB1 levels and prevented organ injury, and increased survival in our model.
