简要总结
Metabolic Syndrome (MS) is a well-known group of obesity-related metabolic disorders including insulin resistance (IR), dyslipidemia and hypertension (HTN). In addition, overweight has a causal relationship with a chronic low grade systemic inflammatory condition and increased intestinal permeability. Over the last decade, this multiplex disorder has progressively become a major worldwide public health problem, because of its association with increased risk of type 2 diabetes mellitus (DM2), atherosclerotic cardiovascular disease and all-cause mortality. Scientific evidence for measures to improve cardiometabolic and intestinal health by non-pharmaceutical means are of urgent need. Administration of the flavonoid hesperidin to those at risk may have beneficial effects on glucose / insulin metabolism, lipid metabolism, blood pressure, heart rate, pro-inflammatory and oxidative stress biomarkers and gut barrier function.
Objective: To determine the 12-week effect of daily administration of hesperidin on the main cardiometabolic disorders related to MS as assessed by investigation of glucose/insulin metabolism, blood lipid profile, blood pressure, heart rate, body composition and gut barrier function in subjects at risk for MS.
Study design: This is a randomized, double-blind, placebo-controlled study with parallel design.
Study population: Healthy (male/female) volunteers, age 18-65, at risk for metabolic syndrome (presenting with 2 out of 5 of the components from NCEP-ATP-III criteria).
Intervention: Participants will be randomly assigned to one of the intervention groups. One group will receive one daily dose of hesperidin capsules while the other group receives identical looking placebo capsules for a period of 12 weeks. The capsules will have to be ingested with a glass of water every morning just before breakfast.
Main study parameters/endpoints: The primary efficacy parameter of this study is the oral glucose tolerance test (OGTT), a validated surrogate endpoint to study the β-cell function and insulin sensitivity. Secondary endpoints entail the evaluation of effects of daily administration of hesperidin on lipid profile (blood measurements), blood pressure and heart rate, body composition, low-grade inflammation biomarkers (blood measurements) and gut barrier function (blood measurements, fecal samples, urine collection).
