Abstract

Supplementation with n-3 fatty acids may improve long-term outcomes of renal transplant recipients (RTR). Recent evidence suggests that EPA and DHA have different outcomes compared with alpha-linolenic acid (ALA). We examined the prospective associations of EPA-DHA and ALA intakes with graft failure and all-cause mortality in 637 RTR. During 3.1 years (interquartile range 2.7, 3.8) of follow-up, forty-one developed graft failure and sixty-seven died. In age-and sex-adjusted analyses, EPA-DHA and ALA intakes were not associated with graft failure. EPA-DHA intake was not significantly associated with mortality (hazard ratio (HR) 0.79; 95% CI 0.54, 1.15 per 0.1 energy% difference). ALA intake was significantly associated with mortality (HR 1.17; 95% CI 1.04, 1.31 per 0.1 energy% difference). This association remained following adjustments for BMI, proteinuria and intakes of fat, carbohydrate and protein. RTR in the highest tertile of ALA intake exhibited about 2-fold higher mortality risk (HR 2.21; 95% CI 1.23, 3.97) compared with the lowest tertile. In conclusion, ALA intake may be associated with increased mortality in RTR. Future RCT are needed to confirm these results.
