Several studies have shown that serum procalcitonin levels increase conspicuously in acute and systemic inflammatory diseases. However, there is insufficient information concerning its activity in chronic infectious diseases such as tuberculosis. In this study, we aimed to assess serum level of procalcitonin in patients with active pulmonary tuberculosis and in medical staff at high risk due to close patient contact (high-risk staff). ⋯ This study showed that procalcitonin levels increased both in patients with pulmonary tuberculosis and in the staff. This result considered that procalcitonin could be a good indicator of inflammation in patients with chronic diseases and in persons exposed to long-lasting infections.
