Abstract
• The clinical course and aluminum status of 38 patients who had been receiving dialysis for at least eight years and were still undergoing dialysis in 1985 were evaluated. Twenty-nine had evidence of increased aluminum burden, although only three had evidence of overt aluminum toxicity, and nine did not have evidence of increased aluminum burden. The patients in both the high- and low-aluminum group were similar with regard to age, the cause of their renal failure, presence of hypertension or coronary artery disease, previous parathyroidectomy, and a number of biochemical parameters, along with the amount of prescribed aluminum. All patients were followed up for the next two years or until they died. The amount of ingested aluminum was reduced, and in selected patients, treatment with intermittent infusions of deferoxamine mesylate was instituted. There were no deaths in the low-aluminum group, but ten of 29 died in the high-aluminum group: seven of vascular disease and three of infection. In addition, morbidity as defined by hospitalization for coronary or cerebral vascular disease or infection occurred in only two of the nine patients in the low-aluminum group and in 19 of the 29 patients in the high-aluminum group. These observations imply that the occurrence of increased body aluminum, as suggested by aluminum blood levels or by results of bone biopsies in some patients, has an adverse effect on morbidity and mortality and should be considered as a possible independent risk factor in patients who are receiving long-term hemodialysis.
