The hypothesis of the proposed project is that after a fat overload, the postprandial response is different in both groups, suggesting that the LPP will present the most significant damage in endothelial vasomotion in obese individuals, especially those with GI and T2DM. After the fat overload, we hypothesized that there will be a worsening of endothelial function and microvascular reactivity in OB/DM2 and OB group compared to C, but also find lower concentrations of incretins in OB/DM2 group compared to other groups.

These hypotheses may be confirmed by techniques for evaluating microvascular function, the use of DFT skin for vasomotion evaluation and finally analysis of analytes through metabolic and cardiovascular read by Multiplex kit.

Condition Intervention
Dietary Supplement: High fat meal

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Diagnostic
Official Title: Evaluating the Effect of Lipid Overload in Endothelial Function and Microvascular Reactivity in Young Obese Women

Further study details as provided by Rio de Janeiro State University:

Primary Outcome Measures:
  • Microvascular function [ Time Frame: up to 180 minutes after high fat meal ]

Secondary Outcome Measures:
  • incretins hormones [ Time Frame: basal, 30, 60, 120,180 minutes after high fat meal ]
    We will assess incretins hormones by multiplex

Enrollment: 60
Study Start Date: September 2012
Study Completion Date: July 2014
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Obese Group
Obese group with fat overload intake.
Dietary Supplement: High fat meal
Control Group
Control Group + fat overload intake
Dietary Supplement: High fat meal
Glucose Intolerance
glucose intolerance + fat overload intake
Dietary Supplement: High fat meal

Detailed Description:

Will be recruited 60 women aged 19-40 years, with a diagnosis of obesity (BMI ≥ 30 kg/m2) treated at the obesity clinic at the State University of Rio de Janeiro (UERJ)at Brazil.

Microcirculation parameters and blood tests will be assessed at baseline and after this, the women will receive a high-fat meal containing croissant, salami, whole milk and cheddar cheese. After 30, 60, 120 and 180 minutes this meal the microcirculation will be evaluated as well as blood collection.
