About this study

Official title: Effect of Cyclosporine and Remote Ischemic Preconditioning on MDA, Calcium Cytosol Concentration, and Mitochondrial Edema in Reperfusion Ischemia Injury: Research on Tetralogy Fallot Patients With Correction Surgery

The study aimed to evaluate the combined effects of cyclosporine and remote ischemic preconditioning on MDA, calcium cytosol concentration, and mitochondrial edema in tetralogy Fallot patients undergoing corrective surgery.

Read the detailed description

Forty patients undergoing tetralogy Fallot corrective surgery were randomized to RIPC and cyclosporine (n=20) and control (n=20). Cyclosporin was administered 2 hour pre induction of anesthesia with the dose of 3 mg/kg body weight intravenously. RIPC was performed preoperatively after induction of anesthesia by inflating pressure cuff on the extremity 30 mmHg higher than systolic blood pressure of the patient for 5x5 minutes with 5 minutes reperfusion interval. Blood samples from coronary sinus and biopsies from the myocardial infundibulum were obtained three times at the condition of pre ischemic, ischemic, and reperfusion. MDA was measured from the blood samples, meanwhile calcium cytosol concentration and mitochondrial edema was measured from the biopsy samples.

What is being measured

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

  1. Malondialdehyde (MDA)

    ROS level is determined by measuring MDA concentration (nmol/mL)

    Measured: 1 year

  2. Calcium cytosol concentration

    Calcium concentration (nmol/mL) in cytosol is determined by ratiometric analysis on Fura Red- dyed heart cells.

    Measured: 1 year

  3. Mitochondrial edema

    Mitochondrial edema (%) is measured by decreasing of optical density that indicates change in mitochondrial matrix volume.

    Measured: 1 year

Secondary outcomes (4)
  1. Cardiac index

    Examined with echocardiography, unit of measurement is litres per minute per square metre (L/min/m2).

    Measured: 1 year

  2. Troponin I

    Measured from venous blood, unit of measurement is nanograms per milliliter (ng/mL).

    Measured: 1 year

  3. Creatine kinase- MB (CKMB)

    Measured from venous blood, unit of measurement is units per liter (IU/L).

    Measured: 1 year

  4. Vasoactive inotropic score (VIS)

    VIS was calculated as: dopamine dose (μg/kg/min) + dobutamine dose (μg/kg/min) + 100 × epinephrine dose (μg/kg/min) + 10 × milrinone dose (μg/kg/min) + 10 000 × vasopressin dose (unit/kg/min) + 100 × norepinephrine dose (μg/kg/min).

    Measured: 1 year

Where is the study taking place?

The record lists 1 site in Indonesia. 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?

Malondialdehyde (MDA) (time frame: 1 year). The study lists 3 primary outcomes in all. 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 NCT05691764, which also lists 4 linked publications.

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?
