About this study

Official title: Prognostic Value of Urinary TIMP-2/ IGFBP7 in Intra-Arterial Contrast-Associated Acute Kidney Injury

Radiological examinations that require the administration of iodinated contrasts (IC) for diagnostic and therapeutic purposes are essential in current clinical practice, and their use in interventional procedures has been progressively increasing.

IC can cause kidney damage, so there is caution in their use in at-risk populations. This fact may limit its diagnostic use, with data on underutilization of interventional techniques in patients with renal insufficiency, which worsen their prognosis.

In addition, once the use of IC contrasts is decided, preventive measures, such as hyperhydration,are used and can have potential side effects, especially in patients at risk of heart failure (acute coronary syndrome, low left ventricular ejection fraction).

New biomarkers of kidney damage have recently been developed, based on the detection of molecules expressed by the kidney in situations of early damage. The quantitative determination of cell cycle arrest proteins (Tissue Inhibitor of metalloproteinase 2 (TIMP2) and Insulin-Like Growth Factor Binding Protein -7 (IGFBP7)) can be predictive of the development of moderate to severe contrast-associated acute kidney injury.

Urinary determination of [TIMP-2] x [IGFBP7] in patients with ACS (acute coronary syndromes) before cardiac catheterization would allow early identification of those patients vulnerable to IC-induced toxicity and adjustment of preventive measures.

Read the detailed description

Urinary determination of [TIMP-2] x [IGFBP7] in patients with ACS undergoing cardiac catheterization would allow early identification of those patients vulnerable to IC-induced toxicity and adjustment of both appropriate preventive measures.

A prospective, descriptive observational study will be carried out to determine sensitivity and specificity of the urinary determination of TIMP2-IGFBP7 and predictive values in the early diagnosis of contrast-associated acute kidney injury (AKI) in patients admitted to the Coronary Care Unit (CCU) in a spanish hospital.

OBJECTIVES

  • PRIMARY OBJECTIVE: To determine the operational characteristics (sensitivity, specificity) of the TIMP2-IGFBP7 biomarker in routine clinical practice, in the early diagnosis of contrast-induced AKI (acute renal injury) in patients admitted to the CCU, exposed to iodinated contrasts. The established renal failure is defined as KDIGO (Kidney Disease Improving Global Outcomes) stage ≥ 2 in the 24 to 72 hours after the administration of contrasts.
  • SECONDARY OBJECTIVES

Evaluate these parameters according to the patient's initial risk level:

  • Estimated renal function upon admission
  • Initial severity estimated by GRACE score
  • Sex
  • Age
  • Contrast media type and volume
  • Patient weight
  • Dose of contrast
  • Diabetes

A single determination (10 ml of fresh urine) should be collected in a sterile container and the laboratory should centrifuge them within the time of collection. Neither the attending physicians nor the investigators will know the results, and the treatment will not be influenced.

The result is reported as a single value which is the concentration of TIMP-2 (ng / mL) multiplied by the concentration of IGFBP7 (ng / mL) divided by 1000. The result is reported without any unit or concentrations of individual biomarkers. As previously reported, a value of> 0.3 identifies patients with a high probability of presenting a moderate to severe AKI (acute kidney injury) in 12 hours, while a value of ≤ 0.3 identifies patients with a low risk of developing a moderate to serious AKI

An aliquot of urine will be stored at -80 ° C in the Clinical Analysis Department

What participants receive

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

  • Urinary determination of TIMP-2/ IGFBP7Diagnostic test

    Urinary determination of TIMP2-IGFBP7 in the an urine sample obtained within 12 hours prior to contrast administration. A single determination will be made, which will be sent to the laboratory. The doctor who treats the patient will not know the result of the test, and the treatment will not be influenced by the result.

    According to the manufacturer, 10 ml of fresh urine should be collected in a sterile container and the laboratory should centrifuge them within the time of collection.

    The result is reported as a single value calculated as the concentration of TIMP-2 (ng / mL) multiplied by the concentration of IGFBP7 (ng / mL) divided by 1000. The result is reported without units.

What is being measured

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

Questions about this trial

What is this clinical trial studying?

An observational study of Contrast-induced Nephropathy, run by Eva de Miguel Balsa at 1 site in Spain.

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 7 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 17 Aug 2021. 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 Spain. 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?

Contrast-Associated Acute Kidney Injury (time frame: up to 72 hours of exposure). 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 17 Aug 2021.
