[Clinical significance of soluble interleukin-2 receptor in patients with pulmonary tuberculosis].

The levels of soluble interleukin-2 receptor (sIL-2R) among patients with various pulmonary diseases were measured by using sandwich ELISA. The levels of sIL-2R were significantly elevated in patients with active pulmonary tuberculosis and acute pneumonia when compared with healthy controls. The concentrations of sIL-2R in patients with active pulmonary tuberculosis decreased in accordance with improvement of other laboratory parameters. The clinical significance and possible mechanism of increasing of sIL-2R in patients with pulmonary tuberculosis were discussed.
