Hypercalcemia in patients with advanced chronic renal failure not yet requiring dialysis.
Six patients with progressive chronic renal failure not yet requiring dialysis and not consuming supplemental calcium or vitamin D developed hypercalcemia. Three had proven and 1 suspected tertiary hyperparathyroidism, 1 parathyroid carcinoma and 1 aplastic bone. None of the 3 patients who underwent bone biopsy had heavy bone aluminum staining. The patients with proven parathyroid-mediated hypercalcemia had marked elevation of C-terminal parathyroid hormone and alkaline phosphatase values and, when performed, radiographs consistent with osteitis fibrosa. When these findings are absent or the diagnosis is otherwise uncertain, a bone biopsy may provide a definitive diagnosis and guide management.
