简要总结
Atherosclerosis, one major cause of morbidity and mortality worldwide, is a complex and multifactorial disease triggered especially due to high level of plasma lipids and that involves three mainly conditions: chronic inflammation, dyslipidemia and oxidative stress. Taking into account the high costs of disease management, eminent suboptimal response and low compliance to drug therapies, the combined use of natural bioactive compound able to reduce atherosclerosis risk could provide an additional protection. In this study, the effects of three bioactive components, namely omega-3 fatty acids, plants sterols and polyphenols present in green tea, will be evaluated over atherosclerosis biomarkers in individuals with dyslipidemia controlled by drugs. It will be carried out a randomized, double-blind, placebo-controlled, crossover clinical study, with participation of 70 subjects. At each intervention period, study participants will receive a packaged for the functional or placebo treatment. Functional treatment packaged will be composed by omega 3 softgels (fish oil), a chocolate containing plant sterols and green tea. Placebo treatment will be composed by corn oil softgels, regular chocolate, and anise tea. Subjects will be advised to consume the softgels and chocolate twice a day after main meals and to drink two cups of tea per day. After evaluation of inflammation, dyslipidemia and oxidative stress biomarkers, subjects with the greatest response to the functional treatment will be selected for additional 6 weeks of functional intervention associated to a reduction of the hypolipidaemic drugs intake, which will be prescribed individually after evaluation of the responsible physician.
详细描述
From eligible subjects, 70 participants will be recruited for a first visit, when they will give informed consent. Also at the first visit, medical reports will be confirmed by each participant, anthropometric measures will be recorded and blood samples will be collected. After first blood analysis results, participants with stable parameters will be called for a second visit when they will be enrolled in a randomized, placebo-controlled, crossover trial, with 4 treatment periods of 6 weeks each, corresponding to a total of 7 visits. At each visit, blood samples and anthropometric measures will be collected. At the first intervention period, study participants will receive a packaged for the functional or control treatment. Functional treatment packaged will be composed by omega 3 softgels (fish oil), chocolate containing plant sterols and green tea. Control treatment will be composed by soy oil softgels, regular chocolate, and anise tea. Subjects will be advised to consume 3 softgels and 1 chocolate twice a day, after main meals, and to drink two cups of tea per day. After a 6-weeks washout period (third visit), the groups will be switched (crossover) and participants will receive the functional or control treatment for more 6 weeks (fourth visit). After biomarkers evaluation, the subjects with the greatest response to the functional treatment will be selected for additional 6 weeks of functional intervention associated to a reduction of the hypolipidaemic drugs (statin) dosage, which will be prescribed individually and by the evaluation of the responsible physician.
