About this study

Official title: Intravenous High Dose of N-acetylcysteine and Sodium Bicarbonate for the Prevention of Contrast-induced Acute Injury: a Randomized Controlled Trial

Contrast-induced acute kidney injury is a common cause of acquired in-hospital renal insufficiency and is associated with prolonged hospitalization and unfavorable early and late outcomes. The investigators sought to compare 4 different strategies (intravenous high-dose of N-acetylcysteine, sodium bicarbonate, the combination of both, and saline alone) in the prevention of contrast-induced acute kidney injury in patients undergoing coronary angiography using high-osmolar contrast media defined by creatinine and cystatin C serum levels.

Being tested
Sodium bicarbonate plus saline, Intravenous NAC plus saline, NAC plus sodium bicarbonate plus saline, Saline, NAC plus saline
Keywords

What participants receive

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

  • Sodium bicarbonate plus salineDrug

    Sodium bicarbonate solution (Sodium bicarbonate 8.4%, Equiplex, Brazil) was given by adding fifteen ampoules of sodium bicarbonate (150 mEq of sodium) to 1 L of 5% dextrose. Infusion in bolus began 60 min prior to the start of contrast administration at 3.5 ml/Kg/h, decreased to 1.18 ml/Kg/h during the contrast exposure and for the next 6 hours after the procedure. Saline (0.9 percent) was given IV at a rate of 1 ml/Kg/h over 60 min prior to the start of contrast administration and followed at the same rate during and for the next 6 hours after the procedure.

  • Intravenous NAC plus salineDrug

    Acetylcysteine (Flucistein 100 mg/ml, Neo Química, Brazil) was given via IV bolus at a rate of 150 mg/kg in 500 ml dextrose 5% over 60 min immediately before contrast exposure and followed by 50 mg/kg in 500 ml dextrose 5% during the contrast exposure and for 6 hours after the procedure. Saline (0.9 percent) was given IV at a rate of 1 ml/Kg/h over 60 min prior to the start of contrast administration and followed at the same rate during and for the next 6 hours after the procedure.

What is being measured

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

  1. The development of contrast-induced acute kidney injury based either on the creatinine and/or Cystatin C increase between day 0 and 72 hours.

    The primary end point of the study was the development of contrast-induced acute kidney injury based either on the creatinine and/or Cystatin C increase between day 0 (when contrast media was administered) and 72 hours (creatinine; Cystatin C increase ≥ 0.3 mg/dL increase and/or 10% increase, respectively within 72 hours after contrast media administration).

    Measured: 72 hours

Secondary outcomes (1)
  1. The secondary end point was development of CI-AKI in a subgroup of high-risk patients, including patients with diabetes mellitus and those with pre-existent kidney disease defined as calculated creatinine clearance < 60 ml/min/1.73m2.

    Measured: 72 hours

Questions about this trial

What is this clinical trial studying?

A study testing Sodium bicarbonate plus saline, Intravenous NAC plus saline and NAC plus sodium bicarbonate plus saline in people with Acute Renal Failure, run by Federal University of São Paulo at 1 site in Brazil.

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 11 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 5 Jun 2012. 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 Brazil. 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. Some participants in this study may receive a placebo. 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?

The development of contrast-induced acute kidney injury based either on the creatinine and/or Cystatin C increase between day 0 and 72 hours. (time frame: 72 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01612013, which also lists 1 linked publication.

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 5 Jun 2012.
