A histochemical stain for bone aluminum allowed us to determine the prevalence and staining characteristics of aluminum in renal osteodystrophy. The staining method correlated well with the results of atomic-absorption studies in 96 samples (r = 0.81; P<0.001). We examined 315 bone-biopsy samples. No aluminum was seen in controls or patients with nonrenal bone diseases. In renal osteodystrophy, the mean level of stainable aluminum was significantly higher in osteomalacic lesions (1.12±0.09 mm per square millimeter of tissue area) than in mild, mixed, or fibrotic lesions (0.43±0.06, 0.34±0.11, and 0.10±0.03 mm per square millimeter, respectively; P<0.001). Seventy per cent of osteomalacic samples had heavy aluminum staining. The bone-apposition rate, measured by double tetracycline labels, was low in 89 per cent of the samples with high levels of aluminum. The mean level of stainable bone aluminum in patients who had a clinical response to calcitriol was significantly lower than in those who did not respond (0.13±0.4 vs. 1.06 ±0.9 mm per square millimeter; P<0.01).We conclude that aluminum deposition is associated with impaired bone formation or mineralization and with a poor response to calcitriol therapy.
