Brief Summary

The metabolic syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers from the disease and predispose the onset of diseases like cardiovascular disease and diabetes mellitus type 2. The first line of treatment for metabolic syndrome is diet and exercise but patients have a low attachment to the treatment, so pharmacologic therapy is required. There is no a single drug that could help to the treatment of all metabolic syndrome components. Irvingia gabonensis, better known as African mango, is widely consumed in central and western Africa, mainly the fruit and seeds. Besides being part of the diet of African the seeds have been used for the treatment of diseases such as dysentery, diabetes and as an analgesic. Resent investigations have demonstrated that an extract of African mango seeds induce significantly weight loss in subjects with obesity, and also improves some biochemical parameters such as glucose and the lipid profile. The aim of this study is to evaluate the effect of Irvingia gabonensis on metabolic syndrome, insulin secretion and insulin sensitivity.

Outcome Measures

Primary Outcomes (9)

  • Fasting Glucose Levels at Week 12

    Fasting glucose will be evaluated at baseline and week 12 with enzymatic-colorimetric techniques

    12 weeks

  • Triglycerides Levels at Week 12

    Triglycerides will be evaluated at baseline and week 12 with enzymatic-colorimetric techniques

    12 weeks

  • High Density Lipoprotein (HDL-C) Levels at Week 12

    The HDL-C will be evaluated at baseline and week 12 with enzymatic-colorimetric techniques

    12 weeks

  • Systolic Blood Pressure at Week 12

    The systolic and blood pressure will be evaluated at baseline and at week 12 with a digital sphygmomanometer

    12 weeks

  • Diastolic Blood Pressure at Week 12.

    The diastolic and blood pressure will be evaluated at baseline and at week 12 with a digital sphygmomanometer

    Baseline. Week 12

  • Waist Circumference at Week 12

    The waist circumference will be evaluated at baseline and at week 12 with a flexible validated metric tape

    12 weeks

  • First Phase of Insulin Secretion at Week 12

    The first phase of insulin secretion will be calculated at baseline and week 12 with the stumvoll index from concentrations of glucose and insulin obtained of an oral glucose tolerance test. Human studies support the critical physiologic role of the first-phase of insulin secretion in the maintenance of postmeal glucose homeostasis. First phase of insulin secretion was estimated using the Stumvoll index (1283+ 1.829 x insulin 30' - 138.7 x glucose 30' + 3.772 x insulin 0'), the entered values reflect the first phase of insulin secretion

    12 weeks

  • Total Insulin Secretion at Week 12

    Total insulin secretion will be calculated at baseline and week 12 with the insulinogenic index from concentrations of glucose and insulin obtained of an oral glucose tolerance test. The insulinogenic index is a ratio that relates enhancement of circulating insulin to the magnitude of the corresponding glycemic stimulus. Total insulin secretion was calculated with the insulinogenic index (ΔABC insulin/ΔABC glucose), the entered values reflect the total insulin secretion

    12 weeks

  • Total Insulin Sensitivity at Week 12

    Insulin sensitivity will be calculated at baseline and week 12 with the stumvoll index from concentrations of glucose and insulin obtained of an oral glucose tolerance test. Matsuda Index value is used to indicate insulin resistance on diabetes. Insulin sensitivity was calculated with Matsuda index \[10,000 / √glucose 0' x insulin 0') (mean glucose oral glucose tolerance test (OGTT) x mean insulin OGTT)\]. The entered values reflect the insulin sensitivity

  • Aspartate Aminotransferase at Week 12
