DiabetesPhase 2/3NCT00989339
Effects of Intralipid Versus Olive Oil Infusions on Endothelial Function, Immune Function, Inflammatory Markers
A Phase 2/3 study testing Twenty-four Hour TPN and Saline Infusion in people with Diabetes and Hypertension, run by Emory University.
Trial summary
Recent evidence suggests that increased levels of a circulation fat (free fatty acids or FFAs) can cause high blood pressure and cardiac complications. Intralipid is the only type of fat approved by the FDA for clinical use. It is usually used as nutrition support in malnourished patients. Read more about this study

About this study
Official title: Effects of Intralipid and Olive Oil Infusion on Endothelial Function, Inflammatory Markers, Oxidative Stress, Immune Function, Autonomic Nervous System, Insulin Sensitivity and Carbohydrate Metabolism
Recent evidence suggests that increased levels of a circulation fat (free fatty acids or FFAs) can cause high blood pressure and cardiac complications. Intralipid is the only type of fat approved by the FDA for clinical use. It is usually used as nutrition support in malnourished patients. The investigators' preliminary studies indicate that Intralipid results in a significant rise in blood pressure, blood vessel stiffness, and inflammation in obese subjects. Olive oil can also be used as nutrition support. The effect of olive oil intravenous (IV) on blood pressure and inflammation is not known. In this study, the investigators will compare the effect of Intralipid and olive oil on blood pressure, blood vessel stiffness and inflammation in healthy subjects. The investigators hypothesize that Olive oil emulsions will result in less vascular changes and less inflammatory response than Intralipid solutions. Accordingly, the investigators propose a systematic evaluation of the effects of Intralipid, olive oil and normal saline on blood pressure, endothelial function (vascular stiffness), inflammation in normal subjects.
A group of obese subjects will be admitted to the Clinical Research Center on 3 occasions. Subjects will receive repeated infusions of Intralipid, ClinOleic, and normal saline at 20 ml/hour for 24 hours.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Intralipid is the only type of fat approved by the FDA for clinical use. It is usually used as nutrition support in malnourished patients. The investigators' preliminary studies indicate that Intralipid results in a significant rise in blood pressure, blood vessel stiffness, and inflammation in obese subjects. Olive oil can also be used as nutrition support. The effect of olive oil intravenous (IV) on blood pressure and inflammation is not known. In this study, the investigators will compare the effect of Intralipid and olive oil on blood pressure, blood vessel stiffness and inflammation in healthy subjects.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Twenty-four Hour TPN and Saline Infusion in people with Diabetes and Hypertension, run by Emory University.
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 3 inclusion and 3 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: withdrawn, as of the sponsor's last update on 4 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.
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.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
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?
endothelial function (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 4 Jul 2014.
