About this study

Official title: Assessment of Plasma and NGAL for the Early Prediction of Acute Kidney Injury

The study aims to recruit 156 (54 Acute Kidney Injury (AKI);102 non-AKI) patients undergoing Cardio pulmonary bypass (CPB) surgery, including those with Chronic Kidney Disease (CKD) and multiple co-morbidities. Urine and blood samples collected pre-operatively and then 0, 3, 6 and 18 hours post-CPB will be stored at -80oC until batch analysed for NGAL using the Abbott and BioPorto assays. AKI - defined as a ≥50% rise in serum creatinine (SCr) over baseline, or the requirement for renal replacement therapy (RRT). SCr will be measured pre-operatively (baseline), then 12 hourly for the first 48 hrs post-CPB and thereafter 24 hourly for 5 days. Clinical data collected will include patient demographics, co-morbidities, drug history, pre-operative renal function, surgery details (type, length, CPB time etc.), length of Intensive treatment unit and hospital stay and post-operative complications. Data will then be analysed comparing the two NGAL tests to find out which is superior, whether it is better to use blood or urine and to define optimal NGAL cut-offs and sample timing for predicting AKI. Both the Abbott and BioPorto assays will subject to a laboratory method evaluation prior to the analysis of any patient specimens in order to verify that their performance is acceptable and meets the manufacturer's claims. This will involve measuring the standard parameters used to assess laboratory assay performance e.g. imprecision (reproducibility), linearity, recovery and method comparison etc.

What is being measured

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

    Measured: 24 months

Secondary outcomes (3)
  1. Total stay in Intensive Treatment Unit (ITU) / High-Dependency Unit (HDU)

    Measured: 24 months

  2. Total length of hospital stay

    Measured: 24 months

  3. Mortality

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Kidney Injury (AKI) and Chronic Kidney Disease (CKD), run by The Royal Wolverhampton Hospitals NHS Trust at 1 site in United Kingdom.

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 3 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: finished, as of the sponsor's last update on 15 Jan 2025. 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 United Kingdom. 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?

Acute Kidney Injury (AKI) or requirement for RRT with 7 days of surgery. AKI is defined as a ≥50% rise in serum creatinine over baseline pre-operative levels (RIFLE stage "R"). (time frame: 24 months). 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 15 Jan 2025.
