About this trial

This study looks at how lipoproteins, which are particles in the blood that transport cholesterol, influence heart and blood vessel health. Beyond just their levels, the way these particles function plays a key role in preventing or contributing to disease. In some conditions, like high cholesterol or diabetes, lipoproteins may not work properly, increasing the risk of clogged arteries and other complications.

The investigators aim to study these changes in people with lipid disorders to better understand their impact on blood health and to find new ways to prevent and treat heart disease.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Healthy volunteers

Abnormalities in lipid panels

Able to provide informed consent

Between the age of 18 and 69

Disqualifiers

Drug or alcohol abuse within 6 months or significant mental/psychological impairment

Trial population

We Planning to start recruiting process in July 2024. We will identify potential subjects who are seen in the lipid clinic of Lifespan hospitals by EMR review. We will contact potential subjects at a routine care lipid clinic visit or by phone independent of their routine care visits. Recruitment will take place at the Lipid Clinic at Lifespan Hospital, the Brown campus, and our research lab.

Trial outcomes

Primary outcomes

1

Percentage of platelet aggregation

Platelet aggregation area under the curve will be used as primary endpoint. Specifically, the percentage of platelet aggregation multiple time will be calculated to get area under the curve as a comprehensive marker for platelet aggregation response.

Time frame
5 years

Secondary outcomes

1

Percentage of Activated Platelets as Assessed by Flow Cytometry

Platelet activation will be assessed as a secondary endpoint. The percentage of activated platelets will be measured using flow cytometry, focusing on markers such as P-selectin expression and fibrinogen binding to the GPIIb/IIIa receptor. Measurements will be taken at multiple time points, and data will be summarized using statistical measures such as mean ± standard deviation.

Time frame
5 years
2

Plasma levels of CRP in mg/L

Inflammatory markers will be measured as secondary endpoints to evaluate systemic inflammation. Plasma levels of C-reactive protein (CRP) will be reported in milligrams per liter (mg/L) using enzyme-linked immunosorbent assay (ELISA) or similar validated methods. Data will be summarized using statistical measures such as mean ± standard deviation, and comparisons will be made across study groups and time points.

Time frame
5 years
3

Plasma levels of resolvins in pg/mL

Specialized pro-resolving mediators (SPMs) will be measured as secondary endpoints to assess their role in inflammation resolution. Plasma levels of resolvins will be quantified using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and reported in picograms per milliliter (pg/mL). Data will be summarized using statistical measures such as mean ± standard deviation, and comparisons will be made across study groups and time points.

Time frame
5 years
4

Plasma Levels of IL-6 in pg/mL

Inflammatory markers will be measured as secondary endpoints to evaluate systemic inflammation. Plasma levels of interleukin-6 (IL-6) will be quantified in picograms per milliliter (pg/mL) using enzyme-linked immunosorbent assay (ELISA) or similar validated methods. Data will be summarized using statistical measures such as mean ± standard deviation, and comparisons will be made across study groups and time points.
