This study aims to demonstrate equivalence in terms of molecule removal between continuous hemodialysis using an "enhanced middle molecule clearance" membrane(Ultraflux EMiC2) and continuous hemofiltration using a standard membrane (Ultraflux AV1000S) in ICU patients requiring continuous renal replacement therapy.
In sepsis, the removal of middle molecular weight molecules such as cytokines (also called blood purification), has shown a great interest in intensive care during the last decades. Indeed, these cytokines are involved in the development of the multi-organ failure syndrome when patients are in septic shock. There is some evidence to suggest that extracorporeal therapies (hemofiltration-hemodialysis)are interesting tools to modulate the inflammatory response and to restore the immune homeostasis.
However, hemodialysis using "conventional" membranes does not allow the removal of middle molecules. Conversely, high-volume hemofiltration is an appropriate therapy but it has a lot of drawbacks due to the high ultrafiltration rates (removal of beneficial small molecules, technical and economical issues due to the use of large amounts of fluid replacement). Finally, high cut-off hemofiltration has been reported to be associated with significant albumin loss.
Therefore, continuous "enhanced middle molecule clearance" hemodialysis could be an interesting alternative, making possible the removal of these middle molecules without significant albumin loss and with some theoretical advantages (reduced cost due to the possibility to produce the dialysate from a water circuit, decreased nursing workload).
The aim of this study is to assess the clearances of different kind of molecules (small, middle and large) when continuous enhanced middle molecule clearance hemodialysis is applied to septic patients.

Condition of low SYSTEMIC VASCULAR RESISTANCE that develops secondary to other conditions such as ANAPHYLAXIS; SEPSIS; SURGICAL SHOCK; and SEPTIC SHOCK. Vasoplegia that develops during or post surgery (e.g., CARDIOPULMONARY BYPASS) is called postoperative vasoplegic syndrome or vasoplegic syndrome.
Sepsis associated with HYPOTENSION or hypoperfusion despite adequate fluid resuscitation. Perfusion abnormalities may include, but are not limited to LACTIC ACIDOSIS; OLIGURIA; or acute alteration in mental status.
Increase in blood LACTATE concentration often associated with SEPTIC SHOCK; LUNG INJURY; SEPSIS; and DRUG TOXICITY. When hyperlactatemia is associated with low body pH (acidosis) it is LACTIC ACIDOSIS.
Systemic inflammatory response syndrome with a proven or suspected infectious etiology. When sepsis is associated with organ dysfunction distant from the site of infection, it is called severe sepsis. When sepsis is accompanied by HYPOTENSION despite adequate fluid infusion, it is called SEPTIC SHOCK.
A family of heat-shock proteins that contain a 70 amino-acid consensus sequence known as the J domain. The J domain of HSP40 heat shock proteins interacts with HSP70 HEAT-SHOCK PROTEINS. HSP40 heat-shock proteins play a role in regulating the ADENOSINE TRIPHOSPHATASES activity of HSP70 heat-shock proteins.
