About this study

Official title: Predicting Adverse Kidney Events of Cardiac Surgery-Associated Acute Kidney Injury Using Novel Biomarkers--A Multicenter Observational Study

The aim of this study was to identify and validate novel biomarkers for predict acute kidney injury (AKI) subphenotype, major adverse kidney events and other poor outcomes.

Read the detailed description

Cardiac surgery-associated acute kidney injury (CSA-AKI) is a serious condition that is associated with increased mortality and morbidity. However, the current criteria for assessing the severity of AKI may not adequately capture the heterogeneity of this condition. This can lead to difficulties in identifying treatment effects in specific patient subgroups, which may contribute to the growing number of negative interventional trials in AKI. To address this issue, researchers have developed and validated two subphenotypes of AKI: resolving and nonresolving. These subphenotypes are based on the trajectory of serum creatinine (SCr) levels in the first 3 days after hospital presentation. By stratifying AKI patients based on these subphenotypes, we can better assess their risk and predict outcomes.

Several novel biomarkers have been developed to aid in the early detection of AKI, discrimination of its underlying causes, and prediction of outcomes. However, it remains unclear whether these biomarkers can accurately predict the development of a nonresolving AKI subphenotype. In our present study, we aim to address this gap in knowledge by conducting a large cohort study. Our goal is to identify and validate novel biomarkers that can effectively detect the resolving subphenotype of AKI, as well as predict major adverse kidney events and other poor outcomes.

What is being measured

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

  1. AKI nonresolving subphenotype

    The resolving subphenotype was defined by a decrease of 0.3 mg/dl or 25% in SCr from its maximum during the first 3 days of study enrollment. All subjects with AKI who did not meet this criterion were classified as having a nonresolving subphenotype

    Measured: 7 days

Secondary outcomes (8)
  1. Major adverse kidney events at 30 days

    Major adverse kidney events (MAKE) was defined as the composite of≥25% loss in estimated glomerular filtration rate (eGFR), dialysis, or death. Estimated GFR was calculated from serum creatinine using the MDRD equation.

    Measured: 30 days

  2. Major adverse kidney events at 90 days

    MAKE was defined as the composite of≥25% loss in estimated glomerular filtration rate (eGFR), dialysis, or death. Estimated GFR was calculated from serum creatinine using the MDRD equation.

    Measured: 90 days

  3. Major adverse kidney events at 365 days

    MAKE was defined as the composite of≥25% loss in estimated glomerular filtration rate (eGFR), dialysis, or death. Estimated GFR was calculated from serum creatinine using the modification of diet in renal disease (MDRD) equation.

    Measured: 365 days

  4. Mortality

    Mortality at 30 days, 90 days and 365 days

    Measured: 365 days

  5. Receipt of renal replacement treatment

    Patients received renal replacement treatment during hospital stay

    Measured: 365 days

  6. Moderate and severe AKI

    Kidney Disease Improving Global Outcomes (KDIGO) stage 2 or stage 3

    Measured: 7 days

  7. AKI progression

    worsening of KDIGO stage within 1 week (progressing from stage 1 to either stage 2 or stage 3, or from stage 2 to stage 3).

    Patients diagnosed with progressive or persisting stage 3 AKI (stage 3 AKI for >3 consecutive days) were classified as having AKI progression.

    If patients who presented with stage 3 AKI but not requiring RRT subsequently required dialysis or developing persist severe AKI or death within 7 days, this was considered progression.

    Measured: 7 days

  8. Composite Outcome

    Stage 3 AKI, renal replacement therapy or death through outpatient or telephone follow-up

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Kidney Injury and Critical Illness, run by Shanghai Zhongshan Hospital at 1 site in China.

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 1 inclusion and 6 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: opening soon, as of the sponsor's last update on 10 Jun 2024. 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 China. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Ying Su, Dr. (+86-021-64041990, su.ying@zs-hospital.sh.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

AKI nonresolving subphenotype (time frame: 7 days). 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 10 Jun 2024.
