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.
Patient admitted in Intensive Care Unit before and/or after cardiovascular surgery with at least one organ failure
Exclusion criteria:
DAP : Cohort of patients who received daptomycin as the first line treatment for at least 48 hours for the defined indication
Drug: Daptomycin (DAP) treatment
VAN : Cohort of patients who received vancomycin as the first line treatment for at least 48 hours for the defined indication
Drug: Vancomycin (VAN) treatment
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.
Also known as: Group DAP
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).
