title: Low incidence of hypercalcaemia in tuberculosis in Malaysia.
abstract: In this study we examined the incidence of hypercalcaemia among patients with tuberculosis in Malaysia. Serum calcium concentration and other calcium metabolism parameters were studied in 43 newly diagnosed tuberculous patients from the Kuala Lumpur General Hospital and the National Tuberculosis Centre. Forty-four patients admitted to the medical wards of the General Hospital, Kuala Lumpur were recruited as controls. The incidence of hypercalcaemia was found to be only 1/43 (2.3%). There was no significant difference between the mean serum calcium and other calcium metabolism parameters between the patients and the controls. Despite earlier reported incidences of 30-50%, this study showed that hypercalcaemia in tuberculosis is uncommon in Malaysia.
