About this study

Official title: Acute Kidney Injury During Daptomycin Versus Vancomycin Treatment in Cardiovascular Critically Ill Patients: a Propensity Score Matched Analysis

Acute kidney injury (AKI) is a frequent complication that occurs in 15 to 25% of patients after vascular surgery, and up to 40% of patients after cardiac surgery. AKI compromises seriously short and long-term prognosis of critically ill patients. Several AKI risk factors have been identified including a chronic pathology of the patient such as kidney failure or diabetes, acute kidney injury related to hemodynamic disorders during surgery, including cardiopulmonary bypass, or sepsis, and the use of nephrotoxic agents such as some antibiotics, colloids or iodine contrast agents. Avoiding nephrotoxic agents is therefore strongly recommended in ICU patients, to reduce the incidence of AKI, or to reduce its severity.

The aim of this cohort study was to assess whether the use of daptomycin, was associated to a lower incidence of AKI than vancomycin in cardiovascular ICU patients, with similar efficacy.

This is a retrospective observational study with a propensity score adjustment to reduce the bias of selection for a comparative analysis between two antibacterial treatments used in routine care.

Since treatments were not randomized, the investigators used the propensity score method for primary endpoint analysis. For this, the investigators included the covariates potentially related to treatment and outcome in a multivariate logistic model explaining the choice of treatment. This propensity score was used in the second model as an adjustment covariate included in the multivariate analysis to determine factors independently associated with the primary endpoint (AKI within 7 days).

The main hypothesis is the first line antibiotic treatment with daptomycin leads to less nephrotoxicity than vancomycin in a population known at high risk for AKI and with at least a similar efficacy on clinical success rate.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Daptomycin (DAP) treatmentDrug

    Also called Group DAP

    Group DAP : Daptomycin was administered at a dose of 8 mg/kg in thirty-minutes intravenous infusion every 24 hours in patients without severe impairment of kidney function or every 48 hours in case of GFR below 30 ml/min/m2. The creatine-kinase (CK) level was measured before the initiation of DAP and at least once a week to assess the occurrence of muscular toxicity defined by an increase of CK up to 3-fold the upper superior limit without any evidence of member ischaemia.

  • Vancomycin (VAN) treatmentDrug

    Also called Group VAN

    Group VAN : Vancomycin intravenous treatment was initiated by a loading dose of 30 mg/kg in 1 hour and followed by a continuous maintenance infusion dosing between 15 and 30 mg/kg/d. The VAN dose was adapted to achieve a target serum vancomycin steady-state concentration of 20-30 mg/L assessed by a daily pharmacologic monitoring (therapeutic drug monitoring).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of Acute Kidney Injury (AKI)

    AKI stade 1, 2 or 3 according to KDIGO definition with baseline creatinine given by the last creatinine value before the start of treatment

    Measured: 7 days after the treatment initiation

Secondary outcomes (9)
  1. Incidence of Acute Kidney Injury (AKI)

    AKI stade 1, 2 or 3 according to KDIGO definition with baseline creatinine given by the last creatinine value before the start of treatment

    Measured: 14 days after the treatment initiation

  2. Maximal decrease of glomerular filtration rate (GFR)

    Decrease of GFR, estimated by CKD-EPI formula, from baseline as measured by all serum creatinine determinations during treatment

    Measured: Through study treatment completion, an average of 2 weeks

  3. Incidence of severe renal failure

    AKI stade 2 or 3 according to KDIGO definition or decrease of GFR more than 50% from baseline

    Measured: Through study treatment completion, an average of 2 weeks

  4. Incidence of renal replacement therapy (RRT)

    RRT initiated between the first and the last treatment administrations

    Measured: Through study treatment completion, an average of 2 weeks

  5. Duration of RRT

    Number of days between the first RRT initiation and the end of the last RRT during the ICU stay (excluding RRT performed in a dialysis center for chronic renal failure)

    Measured: Through study completion limited to ICU stay, an average of 2 weeks

  6. Incidence of clinical treatment failure

    defined by either persistent positive cultures, worsening of clinical status, death due to initial infection, or relapse after the end of treatment. It was assessed in case of documented GPC infection

    Measured: 15 days after the end of treatment

  7. Incidence of premature discontinuation of treatment

    defined as a treatment stopped because of adverse event or clinical failure except death

    Measured: Through study treatment completion, an average of 2 weeks

  8. Mortality

    all cause mortality

    Measured: 28 days after treatment initiation

  9. Mortality

    all cause mortality

    Measured: 6 months (180 days) after treatment initiation

Questions about this trial

What is this clinical trial studying?

An observational study of Infective Endocarditis and Infection Related to Ventricular Assist Device, run by University Hospital, Montpellier at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Acute Kidney Injury (AKI) (time frame: 7 days after the treatment initiation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 May 2019.
