Background: Platelet hyperactivity has a crucial role in initiating vascular thrombosis and subsequent cardiovascular disease (CVD).Objective: This study aimed to assess the effect of anthocyanins (AC) on platelet aggregation and activation and lipid profile.Study Design: A total of 26 healthy participants consumed 320 mg of AC/day in the form of Medox® capsules for 28 days.Setting: This study was conducted in the laboratories of the School of Medical Sciences, Griffith University, Gold Coast, Australia.Participants: A total of 26 randomly recruited healthy 25- to 75-year-old participants completed this study.Primary Outcome Measures: Fasting blood samples were collected pre- and post-the intervention period to perform platelet activation studies by measuring platelet surface marker expression of CD41a and P-selectin, and platelet-monocyte aggregates in adenosine diphosphate (ADP) stimulated platelets. Platelet aggregation studies were performed by stimulating platelets with various agonists such as ADP, collagen and arachidonic acid. Full blood examination, coagulation and biochemistry profile analyses were also performed pre- and post-intervention. Flow cytometric analysis showed a significant effect of AC on the expression of P-selectin as measured by the platelet surface expression of CD62p.Results: There was a significant reduction of ADP-stimulated platelet aggregation. Hematologic analysis showed a significant reduction of mean platelet volume, mean cell hemoglobin, and mean cell hemoglobin concentration. Coagulation analysis demonstrated significant attenuation of fibrinogen level in the blood.Conclusion: This study showed inhibition of platelet activity, platelet aggregation and mean platelet volume (MPV). These results suggest that AC has a positive impact on attenuating platelet activity, which might minimize thrombotic risk. [ABSTRACT FROM AUTHOR]- Published

Context • Type 2 diabetes mellitus is an independent precipitating factor for cardiovascular disease (CVD). Heart disease is one of the leading causes of mortality in patients with diabetes, mainly due to macrovascular complications, such as atherosclerosis. Although aspirin is a frequently used therapy for the inhibition of platelet hyperactivity, many studies suggest that aspirin resistance is rising. Objective • The study intended to investigate the benefits of anthocyanin (AC) as an antioxidant with inhibitory effects on platelets and, consequently, its potential usefulness as complementary antiplatelet therapy to attenuate the negative effects of atherosclerosis and CVD in patients with diabetes. Design • The research team performed a literature review. The team conducted a database search from 2007 to 2017 using Library of Congress, LISTA, PubMed, and Web of Science Core Collection databases, using the following keywords: anthocyanins, platelet, cardiovascular disease, and diabetes. Setting • The study took place at the School of Medical Sciences at Griffith University's Gold Coast campus (Southport, Australia). Results • Platelets have a major pathophysiological role of atherosclerosis and consequently CVD in diabetes. Antiplatelet drugs have a potent inhibitory effect of thrombotic and CVD risks in diabetes. Dietary antioxidants including ACs have a potential platelet inhibitory effect. Hence, ACs may act as complementary therapy to reduce CVD in diabetes. Conclusions • Although antiplatelet drugs such as aspirin provide significant action in the management of CVD, aspirin has limited benefits in diabetes. An AC antioxidant has a potential effect as an antiplatelet agent that subsequently can prevent atherosclerosis and CVD and, therefore, AC may be an alternative to other antiplatelet drugs such as aspirin. However, more interventional studies and large-scale clinical trials are necessary to prove the efficiency of AC as an alternative to other platelet-inhibitory drugs. [ABSTRACT FROM AUTHOR]
