Continuous renal replacement therapy (CRRT) showed promising results in the management of critically ill patients with systemic inflammatory response syndrome (SIRS)/sepsis. However, the underlying mechanism is still not very clear. A change of immune homeostasis in critically ill patients during CRRT was observed only to a smaller degree. ⋯ In patients with SAP, HV-CVVH was associated with improved hemodynamics. HV-CVVH restores monocytes functions, especially in patients in the early phase of the disease and without sepsis. These findings suggest a potential role for HV-CVVH in the treatment of SAP.

The objective of this study was to investigate retrospectively the effect of direct hemoperfusion using polymyxin B immobilized fiber (PMX-DHP) in a cartridge to remove endotoxin on inflammatory mediators in septic patients. PMX-DHP was performed 59 times in 40 patients with severe sepsis and septic shock due to gram-negative bacterial infection. Mean age and APACHE II score were 63 years and 22, respectively. ⋯ Blood pyruvate also decreased significantly (p=0.0025). At the same time, mean arterial pressure, pulse pressure, systemic vascular resistance index, and urine output were significantly increased. These results indicated that PMX-DHP could decrease inflammatory mediators and be effective to interrupt the pathogenic sequence leading to septic shock due to gram-negative bacterial infection.
