Changes in calcium levels associated with rhabdomyolysis-induced acute renal failure.

Two patients with acute renal failure (ARF) following marathon running are discussed. The association between rhabdomyolysis and calcium changes in these cases is stressed and a short review of pertinent literature is discussed. It is felt that the calcium changes in ARF are multifactorial. They include parathyroid hormone changes, calcium deposition in muscle, and changes in 1,25-dihydroxycholecalciferol and serum phosphorus levels.
