Aluminum toxicity in patients undergoing dialysis: radiographic findings and prediction of bone biopsy results.

Abstract

Aluminum toxicity in patients undergoing dialysis currently requires bone biopsy for definitive diagnosis. The authors retrospectively reviewed clinical, histologic, and radiographic findings in 63 patients undergoing dialysis. In 30 patients, biopsy specimens were negative for aluminum toxicity, and in 33 patients, specimens were positive. In 21 of the 30 patients who had a negative biopsy specimen, absence of aluminum toxicity could be predicted by a high immunoreactive parathyroid hormone level (greater than 2,000 microliter Eq/ml [2,210 pM]) and fewer than three fractures, by the presence of osteosclerosis on radiographs, or if serum aluminum levels were less than 30 ng/ml. None of the patients who had a positive biopsy specimen met these criteria. In 18 of 33 patients who had a positive biopsy specimen, aluminum toxicity could be predicted by a low immunoreactive parathyroid hormone level (less than 500 microliter Eq/ml [553 pM]) and more than three fractures, or if serum aluminum levels were greater than 300 ng/ml. None of the patients who had a negative biopsy specimen met these criteria. Thus, based on the criteria identified, the aluminum status of 62% of these patients would have been correctly diagnosed.
