  • Title: Serum aluminium in haemodialysis patients: relation to osteodystrophy, encephalopathy and aluminium hydroxide consumption.
    Author: Heaf JG, Nielsen LP.
    Journal: Miner Electrolyte Metab; 1984; 10(6):345-50. PubMed ID: 6503890.
    Abstract:
    The serum aluminium concentration of 82 patients undergoing regular dialysis treatment in a large dialysis department was measured. Duration of known uraemia, total cumulative aluminium hydroxide consumption, present level of aluminium hydroxide consumption and chronic interstitial nephropathy as primary kidney pathology were all positively correlated to serum aluminium concentration. Serum aluminium concentration was positively correlated to the incidence of clinical osteodystrophy and negatively correlated to bone mineral content. There was, however, no correlation to parathyroid hormone concentration or parathyroidectomy. The highest serum aluminium concentration was accompanied by clinical dialysis encephalopathy. The centre uses reverse osmosis for water purification, and there has never been measurable aluminium contamination. On the basis of these findings it is concluded that: the source of aluminium in our patients is aluminium hydroxide consumption and not the dialysis water; aluminium plays no role in the development of osteitis fibrosa; the findings are consistent with the theory that hyperaluminaemia plays a role in the development of osteomalacia, and serum aluminium measurement may be useful in the diagnosis of dialysis encephalopathy.
