About this study
Official title: Inflammatory and Lipid Markers Pre- and Post-LDL Apheresis: A Multicenter Experience
The primary objective of this study is to measure how LDL apheresis affects levels of inflammatory and cholesterol markers in human beings. The investigators will address this question by drawing pre- and post-LDL apheresis blood from patients who are undergoing this procedure. A secondary objective of this study is to learn how specific inflammatory markers behave in our blood in terms of time to rebound back to normal levels. The investigators will address this question by drawing post-LDL apheresis blood at predetermined time intervals.
Read the detailed description
Numerous epidemiological investigations have demonstrated the importance of cholesterol - specifically low density lipoprotein (LDL) - in the development and progression of atherosclerosis. A continuing relationship between cholesterol level and coronary morbidity has been established. The initial approach for managing elevated cholesterol includes lifestyle interventions, namely eating a low fat diet, weight loss in overweight patients, and regular aerobic exercise. Once lifestyle interventions have been applied, pharmacologic therapy becomes a mainstay of therapy, conventionally with a statin followed by adjunctive medicines as indicated. Certain populations that are refractory to aggressive pharmacotherapy, however - such as patients who have familial hypercholesterolemia (FH) - necessitate alternative means of lipid management. Therapeutic considerations in these patients include LDL apheresis and a number of rare procedures such as partial ileal bypass, liver transplantation, portocaval shunting, and possibly gene therapy in the future.
The anti-inflammatory effects of LDL apheresis and its effects on endothelial function are not well known. Considering several pathways of atherogenesis, and inflammation as a central mechanism thereof, LDL apheresis may theoretically provide synergistic benefit of lipid lowering as well as proinflammatory agent lowering that can lead to significantly decreased atherogenesis. This study looks to address these questions by assessing the effects of LDL apheresis on inflammatory and lipid markers.

Questions about this trial
What is this clinical trial studying?
An observational study of Familial Hypercholesterolemia, run by Emory University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 17 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Lipid Marker Change (time frame: 1 month). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01138371, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2013.
