Hypercalcemia in active pulmonary tuberculosis and its occurrence in relation to the radiographic extent of disease. The Southeast Asian Journal of Tropical Medicine and Public Health. 1992 Dec; 23(4): 702-4http://imsear.searo.who.int/handle/123456789/32132The Southeast Asian Journal of Tropical Medicine and Public Health.The prevalence of hypercalcemia in tuberculosis in Hong Kong and its occurrence in relation to the radiographic extent of disease were studied in 57 patients with sputum smear (n = 44) and/or culture positive (n = 13) pulmonary tuberculosis and in five patients with military tuberculosis prior to treatment. Only one (1.6%) patient had a corrected plasma calcium level above the reference range for our laboratory. There was a positive relationship between the corrected plasma calcium levels and the radiographic extent of disease (r = 0.37), p < 0.01). As the occurrence of hypercalcemia in tuberculosis is known to be influenced by the calcium intake, our finding of a low prevalence of "absolute" hypercalcemia in Hong Kong could be related to the low dietary calcium intake in these subjects.engAdultAgedAged, 80 and overCalcium --bloodFemaleHumansHypercalcemia --bloodLung --radiographyMaleMiddle AgedSerum Albumin --analysisTuberculosis, Pulmonary --bloodJournal Article
