Management of hyperparathyroid patients with grave hypercalcemia.
During recent years the total number of patients undergoing surgery for hyperparathyroidism has markedly increased, but the annual number of cases with substantial hypercalcemia has remained unchanged. Parathyroid carcinoma and water clear cell hyperplasia cause more severe hypercalcemia than other kinds of hyperparathyroidism. Grave hypercalcemia due to hyperparathyroidism is more common among the elderly, but can occur during pregnancy and also among children. Occasionally, a patient with hyperparathyroidism can also have another cause of the hypercalcemia and does not become normocalcemic until adequately treated for both. The suspicion of grave hypercalcemia should arise due to its clinical features. Determination of serum calcium and intact parathyroid hormone concentrations establishes the diagnosis. The basic treatment of grave hypercalcemia is to rehydrate the patient and to restore the sodium losses. To further lower the serum calcium value we have found bisphosphonates to be very effective. The definitive treatment of grave hypercalcemia due to hyperparathyroidism is surgery. As a last resort, frail patients with grave hyperparathyroidism can undergo surgery under local anesthesia. Repeat operations can improve the prognosis of patients with metastatic parathyroid carcinoma. Selective venous catheterization with blood sampling for determination of intact parathyroid hormone can be helpful in localizing recurrent disease.
