Abstract
SCOPE Hesperidin exerts cardiovascular beneficial effects, but its mechanisms of action remain undefined. In a previous study we demonstrated that a single dose and a 12-week treatment of hesperidin decreased systolic blood pressure. The aim of this study was to ascertain the action mechanisms of hesperidin consumption in subjects with elevated blood pressure or with stage 1 hypertension, by determining their transcriptomic profile after a single dose or a 12-week treatment. METHODS AND RESULTS For transcriptomic analysis, peripheral blood mononuclear cells were obtained from 37 subjects with elevated blood pressure and stage 1 hypertension from CITRUS study who were randomized to receive for 12 weeks: control drink (CD; n = 11), OJ (containing 345 mg of hesperidin; n = 15) or EOJ (containing 600 mg of hesperidin; n = 11). Before starting the 12-weeks treatment, a single dose study with a 6 h of follow-up in each group was performed. After the single dose consumption, EOJ versus OJ, downregulated DHRS9 gene which is related with insulin resistance. Compared to CD, 12-week treatment of EOJ downregulated 6 proinflammatory genes while after OJ consumption only 1 proinflammatory gene was downregulated. Moreover, 12-week treatment of EOJ versus OJ, downregulated acute coronary syndrome gene related (SELENBP1). CONCLUSION A single dose consumption of EOJ could protect from insulin resistance. Moreover, EOJ decrease the expression of proinflammatory genes after 12-week treatment providing a possible mechanism of action on inflammation pathway.

Plain language summary
Cardiovascular diseases (CVDs) cause around 31% of all deaths worldwide. Certain dietary patterns have been associated with a reduction in CVDs and so the use of natural-based products has gained importance as a preventive strategy. Hesperidin is a bioactive compound found in high levels in citrus fruits. The reported beneficial properties include antitumor, antioxidant, anti-inflammatory; cholesterol and glucose lowering effects. Many animal studies show multiple beneficial effects but are inconclusive in human studies. The aim of this review is to describe the effects of hesperidin on CVD factors and to highlight the individual differences in its bioavailability and effectiveness. The gut bacteria play an important role in this. Hesperidin is not broken down by the normal digestive process and reaches the colon largely intact. It is the job of the gut bacteria to break it down into bioavailable substances that can be absorbed and utilised. The discrepancies observed in some of the results from human clinical trials may be partly due to individual differences, including that of the gut bacteria. Further clinical trials should be considered as well as classifying individuals according to individual differences in metabotypes.
Abstract
Recently, hesperidin, a flavonone mainly present in citrus fruits, has emerged as a new potential therapeutic agent able to modulate several cardiovascular diseases (CVDs) risk factors. Animal and in vitro studies demonstrate beneficial effects of hesperidin and its derived compounds on CVD risk factors. Thus, hesperidin has shown glucose-lowering and anti-inflammatory properties in diabetic models, dyslipidemia-, atherosclerosis-, and obesity-preventing effects in CVDs and obese models, and antihypertensive and antioxidant effects in hypertensive models. However, there is still controversy about whether hesperidin could contribute to ameliorate glucose homeostasis, lipid profile, adiposity, and blood pressure in humans, as evidenced by several clinical trials reporting no effects of treatments with this flavanone or with orange juice on these cardiovascular parameters. In this review, we focus on hesperidin's beneficial effects on CVD risk factors, paying special attention to the high interindividual variability in response to hesperidin-based acute and chronic interventions, which can be partly attributed to differences in gut microbiota. Based on the current evidence, we suggest that some of hesperidin's contradictory effects in human trials are partly due to the interindividual hesperidin variability in its bioavailability, which in turn is highly dependent on the α-rhamnosidase activity and gut microbiota composition.
