[Renal osteodystrophy and its possible correction in patients on chronic hemodialysis]

Results of diagnosis and treatment of renal osteodystrophy are discussed concerning 162 patients with chronic renal failure treated by hemodialysis. In most cases (15%) osteopenia and hyperparathyroidism were revealed. Roentgenologic investigation revealed metastatic calcification mostly in foot vessels, whereas microscopic study of internal organs in the lungs. The increase of calcium concentration in dialysate from 1.75 to 2.5 Mmol/l was not followed by greater calcinosis in patients with hyperphosphatemia. Uremic pruritus was treated by ultraviolet irradiation and administration of prednisolone for 3-5 days. The effect of I alpha-hydroxy-vitamin D3 was studied in 30 patients. Improvement of clinical status and, principally, relief of muscular pains in the extremities was observed as well as positive changes in blood serum biochemical indices.
