However, kidney patients taking fish-oil supplements had fewerproblems with clots, study says. TUESDAY, May 1 (HealthDay News) -- Taking fish-oil supplements doesnot significantly lower the failure rate of grafts used forhemodialysis, a new study finds. The study included about 200 North American kidney-failure patientswith a synthetic tube grafted between an artery and a vein, whichprovides access to the bloodstream for hemodialysis, a process inwhich waste products are removed from the blood. The patients were randomly assigned to take fish-oil capsules or aplacebo daily for one year, starting one week after the graft wascreated. During that time, there was no statistically significant differencebetween the two groups in the proportion of grafts that failed toremain open, according to researchers at the University of Torontoand Toronto General Hospital. Patients taking fish oil were less likely to develop blood clots,however, and went a longer time without developing blood clots. Thefish-oil group also had a lower rate of radiological and surgicalinterventions. The study appears in the May 2 issue of the Journal of the American Medical Association . The patients in the study had an arteriovenous graft, which was theleading method for gaining vascular access among hemodialysispatients in North America in the early 1990s, according to thestudy. But that type of graft fell out of favor due to its highcomplication rates and associated costs. It has been suggested thatomega-3 fatty acids found in fish oils might help preventarteriovenous graft complications. These findings do not support this theory, an expert wrote in aneditorial that accompanied the study. Instead, another type of graft -- arteriovenous fistula -- is thepreferred method, wrote Dr. Bradley Dixon, of the University ofIowa in Iowa City. "However, if a patient cannot obtain a fistula and requires agraft, use of fish oil and an antiplatelet agent appearsreasonable, pending the results of further studies," Dixon wrote.
