About this study

Official title: Curcumin Supplementation Effects on Markers of Cardiovascular Risk, Inflammation, Oxidative Stress and Functional Capacity in Patients With Coronary Arterial Disease

  • General Objective To evaluate the effects of curcumin supplementation on cardiovascular risk markers, inflammation, oxidative stress and functional capacity in participants with coronary artery disease.

Specific Objectives

Assess, before and after supplementation with turmeric:

  • The nutritional status of the participants;
  • Blood pressure;
  • Atherogenic risk;
  • The expression of transcription factors (Nrf2 and NF-kB), antioxidant enzymes (NQO1, HO-1, sirtuin 1 (SIRT-1)), NLPR3 receptor, as well as the levels of inflammatory cytokines (IL-6, tumor necrosis factor-alpha (TNF-α), protein C reactive (PCR), IL-1, IL 18) and vascular cell adhesion protein 1 (VCAM-1) and E-selectin adhesion molecules;
  • Routine biochemical parameters;
  • Lipid peroxidation and oxidized LDL;
  • The 6-minute walk test, the recovery heart rate and the chair lift test;
  • Modifiable risk factors before and after supplementation;
  • The comparison of all parameters between groups.
Read the detailed description

Coronary Artery Disease (CAD) is the leading cause of death worldwide. CAD refers to the pathological process of atherosclerosis that affects the coronary arteries, often leading to obstruction by an atheromatous plaque. Oxidative stress is one of the most potent inducers of vascular inflammation in atherogenesis. Reactive oxygen species (ROS) regulate through nuclear factor kB (NF-kB), transcription factors and genes related to inflammation, thus, activation of NF-kB by ROS in the atherosclerosis patient is associated with vascular dysfunction and thus with inflammation and atherosclerosis. Recently, researchers have discovered a transcription factor identified as nuclear factor-erythroid 2-related factor 2 (Nrf2) transcription factor, which is responsible for the expression of antioxidant response element genes that can inhibit this pathway, thus providing cellular protection. Thus, several nutritional strategies have been studied, including the use of curcumin, a chemical compound of the class of curcumin produced by turmeric root (Curcuma longa). Turmeric is capable of promoting the activation of nuclear factor-erythroid 2-related factor 2 (Nrf2) transcription factor and inflammasome (NLPR3). These factors, in turn, are involved with the activity of nuclear factor kappa-B (NF-kB), a transcription factor that increases the synthesis of inflammatory cytokines. Thus, the present study aims to evaluate the effects of turmeric supplementation on cardiovascular risk markers, inflammation, oxidative stress and evaluation of functional capacity. Perspectives: This study aims to improve the inflammatory and oxidative stress status of patients with CAD with the use of turmeric, and thus try to reduce the risk factors related to the onset and progression of coronary artery disease.

Model description
Is a longitudinal randomized clinical study where participants will be randomized into two groups: Turmeric Group, in which participants will receive 1.5 grams of turmeric 95% curcumin (ACTIVE PHARMACEUTICA LTDA) for 1 month (3 capsules / day containing 500mg each for 4 weeks), and placebo group, where participants will receive capsules containing corn starch. Randomization will be done in blocks.

Questions about this trial

What is this clinical trial studying?

A study testing Curcumin in people with Coronary Artery Disease and Oxidative Stress, run by Universidade Federal Fluminense 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 2 inclusion and 5 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: withdrawn, as of the sponsor's last update on 26 Feb 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 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 was withdrawn before enrolling participants, so there are no results.

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 effects of curcumin supplementation on the expression of transcription factors (time frame: 4 months). 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?
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 26 Feb 2024.
