BACKGROUND: Aluminum toxicity, a complication described in dialysis patients exposed to aluminum-containing phosphate binders or water used in dialysate preparations containing elevated levels of aluminum, can cause significant morbidity. Although physicians monitor patient aluminum levels, the frequency of abnormal aluminum levels has not been reported. METHODS: We retrospectively examined 1,410 measurements of serum aluminum in 207 dialysis patients at the Franklin Dialysis Center (FDC; Philadelphia, PA) from January 1, 2000, through April 3, 2003. We also surveyed serum aluminum levels from a nationwide dialysis provider (DaVita) to more than 43,000 patients. Local dialysis facilities were surveyed to determine the annual frequency of aluminum testing in their patients. RESULTS: Of 1,410 serum aluminum measurements performed at FDC, only 30 abnormal levels (2.1%) were found. DaVita measured approximately 117,000 aluminum levels annually during the last 3 years, of which 2.5% were abnormal. Frequencies of abnormal aluminum levels declined significantly each year at FDC and DaVita. CONCLUSION: The current frequency of abnormal aluminum levels in our dialysis facility and a national dialysis provider is extremely low and has significantly declined.
