RESUMO
Because of the many difficult aspects in the treatment of septic shock and poor outcome of this condition, establishing the most appropriate therapeutic strategy is problematic. Recently, high mobility group box-1 (HMGB-1) has been shown to activate inflammatory responses and to be a late mediator in endotoxemia and sepsis. Therefore, we considered that it might be worthwhile to investigate the therapeutic potential of HMGB-1 blockade in cases of septic shock.Herein, we describe the case of a patient with septic shock with hepatic portal venous gas caused by intestinal obstruction. Hepatic portal venous gas is a rare condition associated with significant radiographic findings and a fatal outcome. Our patient, however, recovered from severe septic shock and was saved by the use of direct hemoperfusion with a polymyxin B immobilized fiber column (DHP-PMX). This treatment resulted in a decrease in the serum levels of endotoxin, interleukin-6 (IL-6), and HMGB-1.
