Study Details

Study Description

Brief Summary

Background

Familial hypercholesterolemia (FH) is an inherited disease in which the level of bad cholesterol (LDL-cholesterol) is increased, leading to an increase in coronary heart disease even if adequately treated with cholesterol lowering medication (statins). Polyunsaturated fatty acids (PUFA) including omega-3 is known to affect the risk for coronary disease, however its effect on patients with FH is not known.

The purpose of the study is to assess the effect of PUFA on patients with FH, with regard to inflammation measured in the blood and the effect on the blood vessels'ability to relax (endothelial function) by means of tonometry.

Hypothesis

Treatment with 4 grams of PUFA a day for 4 months will lead to an improvement in the endothelial function, and the treatment will also lead to a decrease in in several markers of inflammation and in lipids in the blood.

  • Outcome Measures

    Primary Outcome Measures

    1. Reactive Hyperemia Index (RHI) [Baseline]

      Reactive Hyperemia Index (RHI) is a measure for endothelial function by means of tonometry

    2. Reactive Hyperemia Index (RHI) [3 months]

      Measure of endothelial function

    3. Reactive Hyperemia Index (RHI) [6 months]

      Measure of endothelial function

    4. Reactive Hyperemia Index (RHI) [9 months]

      Measure of endothelial function

    Secondary Outcome Measures

    1. Markers of inflammation [Baseline]

      Serological markers of inflammation including cytokines, C-reactive protein (CRP) and complement factors

    2. Inflammatory markers [3 months]

      Serological markers of inflammation including cytokines, CRP and complement factors

    3. Inflammatory markers [6 months]

      Serological markers of inflammation including cytokines, CRP and complement factors

    4. Inflammatory markers [9 months]

      Serological markers of inflammation including cytokines, CRP and complement factors

    Other Outcome Measures

    1. Lipid parameters [Baseline]

      Different fractions of lipids in the blood including LDL-cholesterol, HDL cholesterol, triglycerides and their subfractions

    2. Lipid parameters [3 months]

      Different fractions of lipids in the blood including LDL-cholesterol, HDL cholesterol, triglycerides and their subfractions

    3. Lipid parameters [6 months]

      Different fractions of lipids in the blood including LDL-cholesterol, HDL cholesterol, triglycerides and their subfractions

    4. Lipid parameters [9 months]

      Different fractions of lipids in the blood including LDL-cholesterol, HDL cholesterol, triglycerides and their subfractions
