  • Adult (age ≥18 years or older)
  • Sepsis (Sepsis-3 criteria)

    Arm Label

    To establish the appropriate dosing regimens of newly available antibiotics during CRRT

    Arm Description

    High dose (world standard dose) and low dose CRRT (Japan local) CRRT protocol Vascular access will be obtained by inserting a double-lumen dialysis catheter into the internal jugular or femoral veins. High dose CRRT in Australia, Blood flow through the extracorporeal circuit will be maintained at 150 ml/min. The CVVHF replacement volume will be set at 25ml/kg/hour and bicarbonate-buffered replacement fluids will be added in post-dilutional mode. Low dose CRRT in Japan, Blood flow through the extracorporeal circuit will be maintained at 80 ml/min. CVVHF replacement volume will be set at 15ml/kg/hour and bicarbonate-buffered replacement fluids will be added in the post-dilutional mode. Fluid balance, volume removal and the duration of CVVHF will be determined by the ICU physician based on the patient's individual clinical status.

    Outcomes

    Primary Outcome Measures

    Plasma new antibiotics concentration during continuous venovenous haemofiltration (CVVHF) in critically ill patients receiving infusion of these drugs.
    New drugs are Tedizolid, Daptomycin (anti-MRSA), Tazobactam/ Ceftolozane (anti-gram negative), Metronidazole (Anti-anaerobic). Plasma antibiotics concentrations will be measured at 5 time-points and prefilter and postfilter plasma and filtered-fluid antibiotics levels will be measured at 3 time-points during CVVHF.
    Calculated clearances of new antibiotics during continuous venovenous haemofiltration (CVVHF) in critically ill patients receiving infusion of these drugs.
    New drugs are Tedizolid, Daptomycin (anti-MRSA), Tazobactam/ Ceftolozane (anti-gram negative), Metronidazole (Anti-anaerobic). Total clearance by CVVHF: (Cltotal) = (Cpre - Cpost / Cpre) × Blood flow (ml/min), Clearance by filtration: (Clfil) = (Clfil / Cpre)× replacement volume (ml/min), Clearance by absorption of the filter: (Clab) = (Cltotal) - (Clfil) (ml/min).

    Secondary Outcome Measures

    Concentration of serum creatinine
    Concentration of serum creatinine

    5. Study Description

    Brief Summary
    The mortality in patients with sepsis and severe acute kidney injury requiring continuous renal replacement therapy (CRRT) remains high. Antibiotic therapy is a key treatment of these patients and in recent years new antibiotics have been licensed. However, data is lacking to determine the optimal dosing regimens of these antibiotics for high (Australia and other countries) and low intensity (Japan) of CRRT. Aim To establish the appropriate dosing regimens of newly available antibiotics during CRRT can applied globally.
