BACKGROUND:Dietary fish oil exerts effects on renal hemodynamics and the immune response that may benefit renal-transplant recipients treated withcyclosporine. To evaluate this possibility, we studied the effect of fish oil on renal function, blood pressure, and the incidence of acute rejection episodes in cyclosporine-treated recipients of renal transplants. METHODS: In a randomized, double-blind trial, 33 recipients of first cadaveric kidney transplants who were treated withcyclosporine and prednisoloneingested 6 g of fish oil daily during the first postoperative year (the fish-oil group), whereas another 33 renal-graft recipients treated withcyclosporine and prednisolone ingested 6 g of coconut oil daily for three months after which time it was stopped (the control group). RESULTS: One year after transplantation, the fish-oil group had higher median values than the controls for glomerular filtration rate (53 vs. 40 ml per minute per 1.73 m2, P = 0.038) and effective renal plasma flow (214 vs. 178 ml per minute per 1.73 m2, P = 0.023) and lower mean arterial pressure (103 vs. 118 mm Hg, P = 0.0011). The cyclosporine doses in the two groups were similar. The cumulative number of rejection episodes was 20 in the controls, as compared with 8 in the fish-oil group (P = 0.029). One-year graft survival also tended to be better in the fish-oil group, (97 vs. 84 percent, P = 0.097). CONCLUSIONS: The daily administration of 6 g of fish oil during the first postoperative year has a beneficial effect on renal hemodynamics and blood pressure in renal-transplant recipients treated withcyclosporine. Although the fish-oil group had significantly fewer rejection episodes than the control group, graft survival at one year was not significantly better in the fish-oil group.
