PTH and hyperuricemia: Patients with rhabdomyolysis commonly experience life-threatening complications, including hyperkalemia, hypercalcemia, hyperazotemia, and hyperuricemia, especially in patients with acute renal function damage.[20] Extensive muscle cell damage can cause a large influx of plasma calcium into the damaged muscles, leading to calcium phosphate precipitation and inhibition of calcitriol and parathyroid hormone resistance due to hyperphosphatemia.
