We report a patient with drug and hyperthermia induced rhabdomyolysis who developed acute renal failure. During the oliguric phase of 22 days, there was profound hypocalcemia (lowest ionized calcium of 0.34 mmol/l), associated with appropriately elevated intact PTH levels and high normal 1,25(OH)2D levels. Massive calcification in necrotic muscle occurred during this time. In the recovery phase, hypercalcemia was present lasting 33 days (maximum ionized calcium of 1.99 mmol/L), associated with suppression of PTH secretion, low 1,25(OH)2D3 levels, decreased bone resorption and mobilization of the muscle calcium deposits. This case report illustrates that the changes in serum calcium in rhabdomyolysis-associated acute renal failure are explicable by the deposition or removal of mineral into or from necrotic muscle with the parathyroid and vitamin D changes occurring secondarily.

UI MeSH Term Description Entries
D006996 Hypocalcemia Reduction of the blood calcium below normal. Manifestations include hyperactive deep tendon reflexes, Chvostek's sign, muscle and abdominal cramps, and carpopedal spasm. (Dorland, 27th ed) Hypocalcemias
D009132 Muscles Contractile tissue that produces movement in animals. Muscle Tissue,Muscle,Muscle Tissues,Tissue, Muscle,Tissues, Muscle
D010281 Parathyroid Hormone A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D003891 Desipramine A tricyclic dibenzazepine compound that potentiates neurotransmission. Desipramine selectively blocks reuptake of norepinephrine from the neural synapse, and also appears to impair serotonin transport. This compound also possesses minor anticholinergic activity, through its affinity to muscarinic receptors.
