Omega-3 Fatty Acid Administration in Dialysis Patients

This study has been completed.

The overall goal of this study is to examine the role of fish oil supplementation in ameliorating the inflammatory state of uremia and the related muscle protein catabolism associated with this disease state. We hypothesize that if administered for a period of 3 months, fish oil will improve the chronic uremic inflammation. We further hypothesize that fish oil administration will improve the muscle protein breakdown associated with uremia and inflammation.

Condition Intervention Phase
End Stage Renal Disease Dietary Supplement: fish oil Dietary Supplement: placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Further study details as provided by Alp Ikizler, Vanderbilt University:

Primary Outcome Measures:
  • A decrease in pro-inflammatory cytokine production (TNF-alpha) by peripheral blood mononuclear cells (PBMC) [ Time Frame: 3 months ]
  • A decrease in muscle protein breakdown [ Time Frame: 3 months ]

Secondary Outcome Measures:
  • A decrease in concentration of acute phase reactants (serum C-reactive protein and plasma pro-inflammatory cytokines) [ Time Frame: 3 months ]
  • An increase in concentration of nutritional biomarkers (serum albumin and serum prealbumin) [ Time Frame: 3 months ]
