  Purpose

Aim: to determine the effects of DHA supplementation:

  • on the platelet function through their aggregation and the pathway of arachidonic acid metabolism
  • on redox status on cells and plasma
  • on inflammation in 16 type 2 diabetic patients in a cross-over study comparing DHA (400 mg/day for 2 weeks) vs Sunflower oil (placebo). Each period is separated by a wash-out period of 6 to 9 weeks.

Condition Intervention
Type 2 Diabetes Dietary Supplement: First period DHA Dietary Supplement: Second period DHA

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Investigator)
Official Title: Intake of Low Dose of Docosahexaenoic Acid: Effects on Platelet Functions and Redox Status in Diabetic Patients

Primary Outcome Measures:
  • Platelet function induced by collagen [ Time Frame: 4 blood sampling in 10 to 13 weeks ]

    4 blood sampling are made during the time of study which expand from 10 weeks (washout period of 6 weeks) to 13 weeks (washout period of 9 weeks):

    • first at the beginning of the first period
    • second at the end of the period (2 weeks after beginning)
    • third at the beginning of the second period
    • fourth at the end of the period (2 weeks after beginning)


Secondary Outcome Measures:
  • Evaluation of cellular and plasmatic redox status [ Time Frame: 4 blood sampling in 10 to 13 weeks ]

    blood sampling are made during the time of study which expand from 10 weeks (washout period of 6 weeks) to 13 weeks (washout period of 9 weeks):

    first at the beginning of the first period second at the end of the period (2 weeks after beginning) third at the beginning of the second period fourth at the end of the period (2 weeks after beginning)
