OBJECTIVE: The objective was to determine the effects of omega-3 supplementation on nutritional state and inflammatory markers of hemodialysis patients.
DESIGN AND METHODS: This was a randomized, placebo-controlled trial. Adult patients undergoing maintenance hemodialysis were included. Patients with malignancy, pregnancy, concurrent inflammatory or infectious diseases, or concomitant use of any medication affecting inflammation status were excluded. The omega-3 group received 6 soft-gel capsules of fish oil (180 mg eicosapentaenoic acid and 120 mg docosahexaenoic acid in each) daily for 4 months, and the placebo group received corresponding paraffin oil capsules.Nutrition indices including body mass index; mid-arm muscle circumference; serum concentrations of albumin, prealbumin, and transferrin; and serum levels of inflammatory/anti-inflammatory markers including interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)-α, C-reactive protein, ferritin, parathyroid hormone, and ratios of IL-10 to TNF-α and IL-10 to IL-6 were measured before and after 4 months of intervention.
RESULTS: Twenty patients in the placebo and 25 patients in the omega-3 group completed the study. There were no significant changes in nutritional markers between the omega-3 and placebo groups after 4 months of intervention. Regression analysis adjusting post-treatment values of nutrition markers for baseline values, omega-3 treatment, and patients' baseline demographic and clinical data revealed that omega-3 treatment was a significant independent predictor of increased serum prealbumin level (182.53; 95% confidence interval 21.14, 511.18; P = .11). Although slight reduction of inflammatory state was observed in the omega-3 group, no significant differences were evident in the mean changes of inflammatory and anti-inflammatory markers between the 2 groups with the exception of serum ferritin level and the IL-10 to IL-6 ratio, which significantly changed in favor of omega-3 supplementation (P < .001 and P = .003, respectively).
CONCLUSIONS: Omega-3 supplementation in hemodialysis patients produced a slight attenuation in systemic inflammation without any remarkable effects on nutritional markers.
