简要总结
Fenugreek has been shown to have beneficial effects on various metabolic abnormalities associated with metabolic syndrome (MS). However, no clinical trials have evaluated its effect on all components of MS, insulin sensitivity, and insulin secretion. Therefore, the main objective of this study is to assess the effect of fenugreek seed administration versus placebo on the components of metabolic syndrome, insulin sensitivity, and insulin secretion.
详细描述
A randomized, double-blind, placebo controlled clinical trial will be conducted in 28 patients with metabolic syndrome according to the criteria of the International Diabetes Federation. Patients will be assigned to two different arms: one group will receive fenugreek seed extract (1500 mg/day) or a matched placebo for 12 weeks.
At the beginning and end of the intervention, the following measurements will be taken: body weight, body mass index, waist circumference, body fat percentage, systolic blood pressure, diastolic blood pressure, glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, very-low-density lipoprotein, insulin, creatinine, uric acid, alanine aminotransferase, and aspartate aminotransferase. In addition, insulin sensitivity and insulin secretion will be calculated. Written informed consent will be obtained from all volunteers.

结局指标
主要结局
Waist Circumference (WC)
时间窗: Baseline to week 12 (end of intervention)
Waist Circumference (WC) is evaluated at baseline and after 12 weeks with a flexible tape in the midpoint between the lowest rib and the iliac crest
Systolic Blood Pressure (SBP)
时间窗: Baseline to week 12 (end of intervention)
Systolic Blood Pressure (SBP) is measured at baseline and after 12 weeks with a digital sphygmomanometer
Insulin Sensitivity (IS)
时间窗: Baseline to week 12 (end of intervention)
Insulin Sensitivity (IS) will be calculated at baseline and week 12 with Matsuda index to get insulin sensitivity
Diastolic Blood Pressure (DBP)
时间窗: Baseline to week 12 (end of intervention)
Diastolic Blood Pressure (DBP) is measured at baseline and after 12 weeks with a digital sphygmomanometer
High Density Lipoprotein Cholesterol (HDL-c)
时间窗: Baseline to week 12 (end of intervention)
High Density Lipoprotein Cholestero (HDL-c) is evaluated at baseline and after 12 weeks with enzymatic/colorimetric techniques
Triglycerides (TG)
时间窗: Baseline to week 12 (end of intervention)
Triglycerides (TG) are evaluated at baseline and after 12 weeks with enzymatic/colorimetric techniques
Fasting Plasma Glucose (FPG)
时间窗: Baseline to week 12 (end of intervention)
Fasting Plasma Glucose (FPG) is evaluated at baseline and after 12 weeks with enzymatic/colorimetric techniques
Total Insulin Secretion (TIS)
时间窗: Baseline to week 12 (end of intervention)
Total Insulin Secretion (TIS) will be calculated at baseline and week 12. It is the result of the ratio between the AUC of insulin in a 2-h OGTT and the AUC of glucose in a 2-h OGTT. It allows estimating the proportion of total insulin secretion in relation to plasma glucose concentration.
First Phase of Insulin Secretion (FPIS)
时间窗: Baseline to week 12 (end of intervention)
The First Phase if Insulin Secretion (FPIS) will be calculated at baseline and week 12 with Stumvoll index to get first phase of insulin secretion
