Effects of Docosahexaenoic Acid (DHA) on Cardiovascular Disease on Diabetic Patients

May 23, 2019 updated by: Hospices Civils de Lyon

Intake of Low Dose of Docosahexaenoic Acid: Effects on Platelet Functions and Redox Status in Diabetic Patients

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame

  • third at the beginning of the second period
  • fourth at the end of the period (2 weeks after beginning)
4 blood sampling in 10 to 13 weeks
