Acute Kidney Injury, Sepsis
Conditions
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.
Interventions
Arterial blood samples will be collected just before the commencement of continuous venovenous haemofiltration (CVVHF) and 1 h after the termination of CVVHF. Prefilter and post-filter venous blood samples and filtered fluid will be collected 1 and 3 h after the commencement of CVVHF and at the end of CVVHF.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Plasma new antibiotics concentration during continuous venovenous haemofiltration (CVVHF) in critically ill patients receiving infusion of these drugs. | 72 hours | 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. | 72 hours | 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
| Measure | Time frame | Description |
|---|---|---|
| Concentration of serum creatinine | through study completion, an average of 1 year | Concentration of serum creatinine |
| length of stay in the hospital | up to 30 days, length of stay in the hospital will be calculated using the earliest of date that the subject is medically ready for discharge when captured, the date of discharge | length of stay in the hospital |
| ICU Mortality | at ICU discharge assessed up to 30 days | Mortality at ICU discharge |
| Hospital Mortality | at hospital discharge assessed up to 30 days | Mortality at hospital discharge |
