About this study
Official title: The Effect of EPA on the Serum Activities of Paraoxonase 1, Homocystein, Thiolactonase and Some Indicators of Vascular Inflammation and PON2 Gene Expression in PBMC Ofthe Patients With Type II Diabetes
The aim of this study is to determining of the effects of Eicosapentaenoic acid (EPA) supplementation on serum activities of Paraoxonase-1 and Homocystein thiolactonase, and serum levels of some indicators of vascular inflammation, and the gene expression of PON2 in the peripheral blood mononuclear cell (PBMC) in the patients with type II diabetes mellitus.
Read the detailed description
The aim of this study is to determining of the effects of Eicosapentaenoic acid (EPA) supplementation on serum activities of Paraoxonase-1 and Homocystein thiolactonase and several indicators of vascular inflammation and the gene expression of PON2 in the peripheral blood mononuclear cell (PBMC) in the patients with type II diabetes mellitus. In this randomized, double-blind clinical trial, placebo-controlled, single-center, 36 men and women aged 35-50 years with type 2 diabetes are enrolled in the study from the Iranian Diabetes Association. After signing informed consent, all individuals complete a general information form. a 24-hour food recall for 3 days will be taken from the participants at the beginning and the end of the study,. Selected samples are randomly classified into 2 blocks of groups receiving supplement and placebo. Two groups will be classified (blocked) based on sex. The supplement group, will receive 2 g/day EPA for 8 weeks and the placebo group will also receive placebo (containing 2 g of edible paraffin) (similar in terms of color, shape and size). Patients are recommended to sustain their diets and medication dose (s) during the study and also advised to maintain a constant level of physical activity. Blood samples will be collected after 8-12 hours fasting and anthropocentric variables, biochemical parameters, target gene expression and physical activity before and after the trial will be measured.

Questions about this trial
What is this clinical trial studying?
A study testing EPA Supplement in people with Diabetes Mellitus Type II, run by Tehran University of Medical Sciences at 1 site in Iran.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Aug 2017. 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 Iran. 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?
HbA1c (time frame: Change from Baseline at 8 weeks after the intervention). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03258840, which also lists 1 linked publication.
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 23 Aug 2017.
