About this study
Official title: Evaluate the Effects of Turmeric on Oxidative Stress Markers in HD Patients
Despite advances in prevention of cardiovascular diseases, the incidence of accelerated atherosclerosis in hemodialysis (HD) patients has still remained high. Oxidative stress is considered as a major player in uremia associated morbidity and mortality in HD patients. The aim of this study was to evaluate the effects of turmeric on oxidative stress markers in HD patients.
Read the detailed description
End-stage renal disease (ESRD) is a state of oxidative stress, due to uremic oxidant mediator's accumulation, the activation of phagocytic oxidative metabolism by the dialysis membrane, intravenous iron therapy and the antioxidant depletion caused by hemodialysis (HD). Some trials showed a significant benefit from antioxidant therapy on cardiovascular outcome in HD patients.
Extensive research focused on direct exogenous antioxidants including vitamin C, and vitamin E, in the treatment of cardiovascular disease. Some clinical trials showed no more beneficial effect of exogenous antioxidant supplementation in cardiovascular disease (CVD) and recommended the necessity for a new approach to regulating cellular redox status.
Turmeric (Curcuma longa Linn) is an herb used as a dietary spice and in traditional medicine for centuries. Curcumin, the most active and non-toxic component of turmeric, is a polyphenol, which has been extensively studied for its therapeutic benefits, such as antioxidant. Besides, turmeric has also been effective in attenuation of proteinurea in diabetic nephropathy and lupus nephritis patients.
Curcumin restored the activities of mitochondrial enzymes complexes and thereby attenuated the release of reactive oxygen species. Turmeric appears to be non-toxic to humans even at high doses. However, there is a paucity of information on the effect of turmeric in HD population. We have, therefore, followed up this study to determine the beneficial effect of turmeric on oxidative stress in HD patients.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Turmeric in people with End Stage Renal Failure, run by Shiraz University of Medical Sciences.
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 0 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 24 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.
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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
effects of turmeric on oxidative stress markers (time frame: 8 weeks). 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 24 Jul 2013.
