Protocol summary

Study aim
The aim of this study was to evaluate the effect of portulaca oleracea (purslane) hydroalcoholic extract in patients with non-alcoholic fatty liver disease (NAFLD).
Design
A 12-week randomized, double-blinded, parallel clinical trial on 74 patients with NAFLD.
Settings and conduct
Patients are randomly divided into intervention and placebo groups (37 patients in each group). The study process is described for each patient and a written consent form is obtained from the patients. The degree of hepatic steatosis is determined using ultrasound once at the beginning and again at week 12 of the study. The 3-day of 24-hour dietary recall is taken at the beginning and end of the study. A diet for 10% weight loss will be provided to each patients individually by a nutritionist. Patients' compliance is monitored by telephone every 15 days. Fasting blood samples are taken from patients at the beginning and at end of the study. The study protocol has been approved by the ethics committee of Iran University of Medical Sciences.
Participants/Inclusion and exclusion criteria
Men and women with non-alcoholic fatty liver disease whose ALT is greater than 30 U / l and more than 19 U / L, respectively, and who do not have chronic liver disease, cardiovascular disease, hypertension, or kidney stones are eligible to participate in the study.
Intervention groups
Intervention group: one capsule containing 300 mg of purslane hydroalcoholic extract daily. Placebo Group: A capsule daily similar in appearance to drug capsules, filled with toasted powder.
Main outcome variables
Serum levels of ALT and AST are the main outcomes of the study. Other variables include fasting blood glucose, insulin, total cholesterol, triglycerides, HDL-C, LDL-C, gamma glutamyl transferase, alkaline phosphatase, glutathione peroxidase, total bilirubin, adiponectin, NF-kB and expression of the NF-κB gene.

General information

Reason for update
