Protocol summary

Study aim
This double-blind randomized placebo-controlled clinical trial will be done with the aim of oleoylethanolamide (OEA) supplementation on the SIRT1, AMPK, PGC1-α, PPAR-γ, CEBP-α, CEBP-β, IL-6, and IL-10 genes expression, and serum levels of IL-6, IL-10, hs-CRP, IL-1β, TNF-α, TAC, GSH-Px, SOD, catalase, MDA, ox-LDL, and NRG-4, and body composition in obese patients with non-alcoholic fatty liver disease (NAFLD).
Design
This study will be done on sixty obese patients of both genders with NAFLD.
Settings and conduct
The study will be conducted in the nutrition faculty of Tabriz University of Medical Sciences and supplementation duration will be 12 weeks. The OEA and placebo sachets will be coded by the person responsible for preparing them, and the main investigators and the patients will be blinded to the type of the supplement each group receives.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Body mass index 30 to 40 kg/m2, and non-alcoholic fatty liver disease Exclusion criteria: Use of drugs and supplements. smoking, pregnancy, breastfeeding, menopause, liver, kidney and gastrointestinal diseases, diabetes, heart failure, thyroid disorders
Intervention groups
patients in the OEA group will use two125 mg OEA capsules daily. In the placebo group, two 125 mg capsules of starch will be consumed daily.
Main outcome variables
The body composition percentage The expression of SIRT1, AMPK, PGC-1α, PPAR-γ, CEBP-α, CEBP-β, IL-6, and IL-10 genes serum levels of IL-6. IL-10, hs-CRP, IL-1β, TNF-α, TAC, GSH-Px, SOD, catalase, MDA, ox-LDL, and NRG-4

General information

Reason for update
To add the effects of oleoylethanolamide (OEA) supplementation on the serum levels of hs-CRP, IL-1β, TNF-α, TAC, GSH-Px, SOD, catalase, MDA, and ox-LDL
