Study hypothesisPrimary Question:
Will haemodialysis patients who receive oral fish oil capsule supplementation versus placebo capsule supplementation have a lower proportion of PolyTetraFluoroEthylene (PTFE) grafts without thrombosis, radiological or surgical intervention within 12 months of creation?
Ethics approval(s)Ethics approval received from local research ethics committees.
ConditionEnd Stage Renal Disease (ESRD)
InterventionOral supplementation with four x 1 g fish oil capsules versus placebo capsule supplementation. In addition, standard guideline recommended care of haemodialysis grafts will continue to be followed.

As of 25/10/2006, the anticipated study end date has been extended to July 2009. The previous end date of this trial was 01/07/2007.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Fish oil
Primary outcome measureThe proportion of PTFE grafts with loss of native patency within 12 months
Secondary outcome measuresSecondary Endpoints:
1. The average change in Low-Density Lipoprotein (LDL) and fasting triglyceride from baseline to six months
2. The average difference in levels of Reactive Oxygen Species (ROS) (Malondialdehyde (MDA) and 3-nitrotyrosine) and C-reactive protein at baseline and six months
3. The fatty acid composition of total serum pholspholipids at baseline and six months

Tertiary endpoints (within 12 months):
Will provide information on the long term efficacy of fish oil on graft functioning and explore some of the other potential risks and benefits associated with fish oil consumption, such as its effect on bleeding and blood pressure. Rates and proportions will both be evaluated whenever possible to allow for comparison with the literature:
1. Total rate and proportion of:
1.1. Thrombosis
1.2. Radiological or surgical interventions
2. The time to:
2.1. First thrombosis
2.2. First angioplasty
3. The primary and cumulative patencies
4. The incidence of primary failure
5. Total rate and proportion of minor and major bleeding episodes. A minor bleeding episode is on that requires compression of the bleeding vessel for more than 30 minutes for it to cease without other intervention. A major bleeding episode is defined as one that requires either:
5.1. Blood transfusion
5.2. Correction using other blood products such as fresh frozen plasma
5.3. Admission into hospital to manage the bleeding episode
5.4. Admission into hospital due to complications of the bleeding episode
6. Average change in blood pressure and the number of Blood Pressure (BP) medications from baseline to six months and 12 months. BP will be taken post-dialysis in the sitting position, on three separate occasions in a week and then averaged, during the time points indicated
7. Rate and proportion of cardiac events:
7.1. Myocardial infarction
7.2. Congestive heart failure requiring hospitalisation
7.3. Cardiac related mortality
8. All cause mortality
