Clinical Trial Summary

Dyslipidemia, is a cardiovascular risk factor of great importance whose prevalence has increased over the last decade. Part of the components of metabolic syndrome and consensus so far contemplated to increased triglycerides (TG) and reduced high-density lipoprotein cholesterol (HDL-C) as part of the elements for classification, which includes mixed dyslipidemia.

Currently, fibrates, such as bezafibrate, are drugs used in treating hypertriglyceridemia, besides reducing the risk of coronary disease. However, although this treatment is safe, it is not without risks; with increased prevalence of adverse effects as the dose thereof is increased or joins combination with a statin drug for the treatment of mixed dyslipidemia long term.

Among the alternative therapies is berberine, which to reduce cholesterol and triglycerides may be useful in combination with bezafibrate in the treatment of mixed dyslipidemia and as an option with lower cost and lower frequency of adverse events.

Description:

The aim of this study is to evaluate the effect of berberine plus bezafibrate administration on the lipid profile of patients with mixed dyslipidemia.The investigators will conduct a double-blind randomized pilot clinical trial with parallel groups in men and women aged 30-60 years old with diagnosis of mixed dyslipidemia.

Patients will be assigned to 3 groups:

1. 12 patients will receive berberine, 1500 mg / day

2. 12 Patients will receive bezafibrate 400 mg / day

3. 12 patients will receive a combination of berberine (1500 mg / day) plus bezafibrate (400 mg / day).

All participants will be determined before and after the intervention: lipid profile, total cholesterol (TC), triglycerides (TG), HDL-C, low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein (VLDL).

Also weight, Body Mass Index (BMI), waist circumference (WC), glucose, systolic blood pressure (SBP), diastolic blood pressure (DBP), creatinine (CR) uric acid (UA) and tolerability.

Statistical analysis was performed upon the sample of subjects.

Previous start the statistical analysis of the groups will proceed to verify the behavior of the distribution of the variables included by Z Kolmogorov-Smirnov goodness of fit.

The distribution of all the variables under this test is cataloged in normal or not normal, which define the type of statistical test would be performed (parametric or non-parametric). However, based on the sample size, non-parametric tests will be those considered most suitable for application.

The data obtained will be expressed and presented using measures of central tendency and dispersion for quantitative (mean and standard deviation) variables and qualitative variables are expressed as frequencies and percentages.

Primary	Total Cholesterol After 90 Days.	The blood sample for the determination of total cholesterol was taken after an overnight fast and was evaluated at baseline and after 90 days by spectrophotometry method.	90 days
Primary	Low Density Lipoprotein Cholesterol (LDL-c) After 90 Days	The blood sample for the determination of low density lipoprotein cholesterol was taken after an overnight fast and was evaluated at baseline and after 90 days by spectrophotometry method.	90 days
Primary	High Density Lipoprotein Cholesterol (HDL-c) After 90 Days	The blood sample for the determination of high density lipoprotein cholesterol was taken after an overnight fast and was evaluated at baseline and after 90 days by spectrophotometry method.	90 days
Primary	Very Low Density Lipoprotein After 90 Days	The blood sample for the determination of VLDL was taken after an overnight fast and was calculated at baseline and after 90 days as triglycerides/5.	90 days
