Study summary

The objective of this trial is to study the effects of omega-3 PUFA supplementation on the inflammatory response and lipid profile in patients with chronic Chagas cardiomyopathy.

Study Type: Interventional

Study Design: A total 40 patients will be randomly assigned into two parallel groups. The intervention will be treatment with omega-3 PUFAs at a dose of 3 g/day for 8 weeks, compared to placebo (corn oil). The primary endpoints will be the concentrations of inflammatory markers (IL-1, IL-2, IL-4, IL-6, IL-10, TNF-alpha, IFN-γ, and TGF-β). Secondary endpoints will be the fasting glucose, lipid, and anthropometric profiles.

Read the detailed description

Several studies have shown the beneficial effects of polyunsaturated fatty acids on inflammatory processes, dyslipidemia, and cardiovascular diseases, there are no reports about food intake and PUFA supplementation in chronic Chagas cardiomyopathy patients. Thus, the objective of this study is to assess the effects of omega-3 PUFA supplementation on the lipid profile and the pro-inflammatory and anti-inflammatory cytokine profiles in chronic Chagas cardiomyopathy patients.

After patients are selected by cardiologists, they will be seen by study nutritionists, who will explain the study procedures to the patients and administer the free and informed consent form. The patients who agree to participate in the study will sign the consent form and undergo the initial assessment.

The following data will be collected and evaluated in the study: sociodemographic data (age, sex, ethnicity/race, education, and domicile), clinical data (functional class and vital signs), alcoholism, smoking, prescription drugs, 3-day food record, 24-hour recall, anthropometric assessment (height, weight, BMI, waist circumference, tricipital skinfold thickness, and arm circumference), lipid profile (total cholesterol, triglycerides, HDL-c, LDL-c, and VLDL-c), and cytokines (IL-1, IL-2, IL-4, IL-6, IL-10, TNF-alpha, IFN-γ, and TGF-β). Clinical, nutritional, and anthropometric assessments will take place immediately before starting the intervention and after 4 and 8 weeks during the study; lipid profile and cytokines will be evaluated before the intervention and at the end of 8 weeks. Each patient will be followed for 8 weeks.

Study arms

  • Active comparator
    Omega-3

    This group is receiving omega-3 supplement.

    Dietary Supplement: Omega-3

  • Placebo comparator
    Oil Corn

    This group is receiving the placebo comparator.

    Dietary Supplement: Placebo Comparator

Interventions

What researchers measure

Primary outcomes

  1. Cytokine profile

    The primary endpoint of this study will be the cytokine profile. IL-1, IL-2, IL-4, IL-6, IL-10, TNF-alpha, IFN-γ, and TGF-β will be measured in the serum of patients using specific sandwich enzyme-linked immunosorbent assays. Capture and detection antibodies will be obtained from eBioscience (San Diego, CA, USA).

    Time frame: 8 weeks

Secondary outcomes

  1. Lipid profile

    Total cholesterol, triglycerides, and high-density lipoprotein cholesterol (HDL-c) will be measured with enzymatic-colorimetric assays using Siemens reagents on a Siemens Dimension RXL chemistry analyzer (Siemens Healthcare Diagnostics, Tarrytown, NY, USA). Low-density lipoprotein cholesterol (LDL-c) and VLDL-c will be calculated according to the Friedewald equation

    Time frame: 8 weeks

Other outcomes

  1. Anthropometric measures

    The anthropometric assessment will consist of body mass index (BMI), waist circumference, tricipital skinfold thickness, and arm circumference.

    Time frame: 8 weeks
