title: Evaluation of adrenal function in long standing pulmonary tuberculosis: a study of 100 cases.
abstract: Tuberculosis is a major public health problem in Pakistan and adrenal involvement in long-standing tuberculosis has been found to be common. A multi-center study was conducted to assess the adrenal function using short Synacthen test in one hundred patients with tuberculosis of more than 6 months duration at three hospitals of Rawalpindi and Islamabad. Forty patients demonstrated impaired response to Synacthen test. In 21 (52.5%) the increment from basal level was less than 300 nmol/L with a peak level increasing to over 600 mmol/L in 15 (37.5%) patients, the increment from basal level was less than 300 nmol/L as well as the peak level was also less than 600 nmol/L. In 4 (10%) patients the increment was more than 300 nmol/L but they were not able to obtain a peak level of 600 nmol/L. No significant difference was found between the patients with normal response and the impaired response with regards to their clinical features, duration of illness, body mass index (BMI), blood pressure variation and routine biochemical profile. It is concluded that adrenal dysfunction is common in patients with long-standing tuberculosis. Diagnosis of hypoadrenalism is not possible on clinical grounds and routine biochemical examinations. Synacthen stimulation test is necessary for its diagnosis.
