We wish to compare the effect of using new large hole filters with hemodialysis in patients with severe infections and acute kidney failure to that of standard filters. The new therapy will be considered to be effective if it lowers the amount of drugs used to support blood pressure and if it lowers the blood levels of some “humoral mediators” more than standard therapy. We will also monitor blood levels of important components of blood such as albumin and electrolytes in each group.

Further Details

Primary Outcome Measures:

  • The primary outcome measure for this study is the relative change in plasma IL-6 levels.

Secondary Outcome Measures:

  • The secondary outcome is the clearance and the absolute change in the levels of IL-6 and other cytokines.
  • The other secondary outcome is the change in noradrenaline dose required to maintain baseline mean blood pressure (typically 70 mmHg)
  • Change in the levels of other cytokines.
