Plasma levels of SLPI in HDs and TB patients. A: Plasmatic SLPI levels. SLPI levels were analyzed by sandwich ELISA in plasma from HDs (n = 23) and TB patients (n = 29). B: Association between plasma SLPI levels and disease severity. HD data from A were plot as subjects who had been in contact with TB patients (HCs) and those who had not been in contact with patients (HDs). Patients with TB were also classified as mild, moderate, and severe.²¹ Student’s t-test (A) or analysis of variance post hoc Dunnett’s multiple comparisons test (B) was used. ^∗P < 0.05, between severe and mild TB patients; ^∗∗P < 0.01 (A); ^††P < 0.01 between severe TB patients and HDs or HCs (B).
