Effects of Fish Oil and Red Wine on Oxidative Stress Biomarkers

United States40 participantsStarted 2008-05

Plain-language summary

The American Heart Association and the American College of Cardiology (AHA/ACC) recently encouraged "increased consumption of omega-3 fatty acids in the form of fish or capsule form (1 g/day) for risk reduction" and stated that "for treatment of elevated triglycerides, higher doses are usually necessary for risk reduction" (Smith SC et al. Circulation 2006;113:2363-72). These recommendations are based on conflicting evidence about the efficacy of the omega-3 treatment with data derived from single randomized trials or non-randomized studies (Smith SC et al. Circulation 2006;113:2363-72). Much effort has been undertaken to elucidate the role of omega-3 fatty acids in the development of cardiovascular disease, but even recent meta-analyses deliver no clear picture; they either favor (Mozaffarian D Jama 2006;296:1885-99) or reject (Hooper L Bmj 2006;332:752-60) the hypothesis of cardioprotective effects of omega-3 FAs. The objective of the clinical study is to study the effects of fish oil on blood and urinary markers of inflammation and cell stress. By using different permutations of high-dose supplementation of omega-3 and omega-6 fatty acids versus different alimentary omega-3 fish doses and grain alcohol versus different kinds of red wine, this trial will study how omega-3 fatty acids, ethanol and red wine constituents modulate biomarkers of inflammation and cell stress.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Age between 21 - 60, * Subjects must be in good health as based on medical history, physical examination, vital signs, and laboratory tests. * All Subjects have to adhere to the following criteria: * Must be non-smoking volunteers (both male and non-pregnant females) due to a significant influence of smoking and overweight on the outcome measures of lipid peroxidation, * Must be of normal weight with a body mass index (BMI) ≤ 25. The correlation between the BMI number and body fatness is fairly strong; however it varies by sex, race, and age. These variations include the following examples: At the same BMI, women tend to have more body fat than men; at the same BMI, older people, on average, tend to have more body fat than younger adults; highly trained athletes may have a high BMI because of increased muscularity rather than increased body fatness; source at http://www.cdc.gov/healthyweight/assessing/bmi/adult\_BMI/index.html. Therefore, subjects with a BMI \> 25 can be enrolled at the discretion of the PI in writing. * Female subjects of child bearing potential must be using a medically acceptable method of contraception (oral contraception, depo-provera injection, IUD, condom with spermicide, diaphragm, cervical cap, progestin implant, abstinence, tubal ligation, oophorectomy, TAH) throughout the entire study period. All female subjects must consent to a urine pregnancy test at screening and just prior to the start of each treatment phase of the stud…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
