About this study
Official title: To Study the Effect of High Fat High Carbohydrate Meal on Oxidative Load, Inflammatory Mediators and Insulin Resistance in Normal and Obese Subjects
The main objective of this research is to investigate the effect of addition of fiber on the high fat high carbohydrate (HFHC) meal induced inflammation and oxidative stress mechanisms at the molecular level in humans, in vivo. The investigators have previously shown that the intake of one HFHC meal leads to an increase in oxidative stress and inflammation. HFHC meal also induces an increase in the expression of suppressor of cytokine signaling- 3 (SOCS-3) in the mononuclear cells (MNC), which interferes with insulin signal transduction and contributes to the pathogenesis of insulin resistance. In contrast, an American heart association (AHA) meal rich in fruits and fiber does not induce these effects. These observations are important since HFHC meal not only induces oxidative stress and inflammation but also lays the foundations of a potentially greater insulin resistance through the induction of SOCS-3, TLR-4 and TLR-2.
Read the detailed description
The main objective of this research is to investigate the effect of high fat high carbohydrate (HFHC) meal on inflammatory mechanisms at the molecular level in humans, in vivo versus HFHC meal plus fiber. HFHC meal includes egg muffin, sausage muffin sandwiches and two hash browns. The Investigators have previously shown that the intake of one HFHC meal leads to an increase in reactive oxygen species (ROS) generation and the expression of p47, the key subunit of NADPH oxidase, with a concomitant increase in intranuclear nuclear factor κB (NFkB) binding. More recently, the investigators have also shown that HFHC meal leads to an increase in plasma endotoxin (lipopolysaccharide, LPS) concentrations along with an increase in the expression of Toll like receptor-4 (TLR-4), the receptor for endotoxin, and TLR-2, the receptor for several products of Gram positive bacteria. In addition, it also causes an increase in lipopolysaccharide binding protein (LBP), the protein which facilitates the binding of LPS to CD14 and TLR-4. Finally, HFHC meal also induces an increase in the expression of suppressor of cytokine signaling- 3 (SOCS-3) in the mononuclear cells (MNC) (1), which interferes with insulin signal transduction and contributes to the pathogenesis of insulin resistance. In contrast, an AHA meal does not induce these effects. These observations are important since HFHC meal not only induces oxidative stress and inflammation but also lays the foundations of (2) a potentially greater response to an inflammatory challenge through the induction of an increase in LPS concentrations and the expression of TLR-4 and TLR-2; and (3) insulin resistance through the induction of SOCS-3, TLR-4 and TLR-2.

What is being measured
The primary outcome is the main question the study is designed to answer.
effect of addition of fiber on the relative change of NF-Kappa B
The investigators hypothesize that addition of fiber intake will suppress NF-kappa B after HFHC meal. Therefore, changes in NF-kappa B activity will be compared as percent change form baseline after HFHC meal with or without fiber in lean and obese subjects
Measured: Baseline and 1 week
Secondary outcomes (4)
effect of addition of fiber on Changes in ROS generation.
Changes in Reactive oxygen species (ROS) generation between the 2 visits (HFHC meal with or without fiber) will be compared as percent change from baseline.
Measured: Baseline and 1 week
effect of addition of fiber on Changes in TLR-4 mRNA expression in MNC
Changes in TLR-4 mRNA expression in MNC between the 2 visits (HFHC meal with or without fiber) will be compared as percent change from baseline.
Measured: Baseline and 1 week
effect of addition of fiber on Changes in SOCS-3 mRNA expression in MNC
Changes in SOCS-3 mRNA expression in MNC between the 2 visits (HFHC meal with or without fiber) will be compared as percent change from baseline.
Measured: Baseline and 1 week
effect of addition of fiber on Changes in insulin secretion between the 2 visits (HFHC meal with or without fiber) will be compared as percent change from baseline.
Changes in insulin concentrations between the 2 visits (HFHC meal with or without fiber) will be compared as percent change from baseline.
Measured: Baseline and 1 week

Questions about this trial
What is this clinical trial studying?
A study testing HFHC meal and HFHC MEAL plus Fiber in people with Postprandial Inflammation, run by University at Buffalo 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?

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 May 2016. 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. Some participants in this study may receive a placebo. 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?
effect of addition of fiber on the relative change of NF-Kappa B (time frame: Baseline and 1 week). 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 25 May 2016.
