Hypercalcemia and pulmonary tuberculosis in east Tennessee.

In a study of 83 patients with active pulmonary tuberculosis who were treated in East Tennessee, only three developed hypercalcemia. The incidence of hypercalcemia in East Tennessee is markedly lower than that quoted in earlier studies performed in the United States. The explanation for the infrequent occurrence of elevated serum calcium in our population is probably multifactorial, but does not appear to be related to the selection of antituberculous agents.
