Correlation Between Intestinal Microbiota, Inflamatory Biomarkers, Intestinal Morphology, Hepatic Fibrosis Degree and Vascular Reactivity in Patients With Different Degrees of Glucose Tolerance and Body Adiposity.

This project aims to establish the correlation between intestinal microbiota with inflammatory biomarkers, intestinal morphology, vascular reactivity and degree of hepatic fibrosis in patients with different degrees of glucose tolerance and body adiposity.

Study Overview

Status

Completed

Detailed Description

Obese patients with dysglycemia or not, from the Obesity Outpatient Clinic, and individuals with normal or overweight weight with dysglycemia or not, preferably from the same social class and type of diet of the obese will be invited to participate in the study. Dysglycemia will be defined by the criteria of the Brazilian Society of Diabetes. These individuals will be divided into four groups: obese with dysglycemia (OBD), obese with normoglycemia (OB), lean / overweight with dysglycemia (MD) and lean with normoglycemia (M). After the selection and signing of the informed consent, the patient will be referred for an anthropometric evaluation, with the measurement of body mass and height, waist circumference and determination of body fat by the bioimpedance method Biodynamic 450 (BioDynamics , Seattle, USA). Finally, the 24-hour reminder (R24h) will be applied as a food survey method. And the dietary calculation will be performed through the AVANUTRI® diet calculation program (Rio de Janeiro, Brazil). Clinical parameters will include: age, sex, BMI, presence of comorbidities, use of medications, gastrointestinal complaints, previous surgeries and smoking (absent, present, prior). Only after approval by the Research Ethics Committee (CEP) of the Pedro Ernesto University Hospital (HUPE-UERJ), will this recruitment begin.
