Abstract: Methods, devices, kits and computer-implemented methods for diagnosing (and optionally treating) tuberculous meningitis (TBM) are provided. In one embodiment, the method comprises testing a cerebrospinal fluid (CSF) sample from a subject suspected of having TBM for the presence of MPO and at least two other biomarkers, at least one of the other biomarkers being selected from the group consisting of IFN-?, sICAM-1, VEGF-A and CXCL8. For example, the method can comprise testing the sample for MPO, IFN-? and VEGF-A or for MPO, IFN-?, sICAM-1 and CXCL8. In another embodiment, the method comprises testing a blood sample from a subject suspected of having TBM for the presence of at least one biomarker selected from the group consisting of adipsin (complement factor D), Ab42 and IL-10, and at least two other biomarkers. In one example, the method comprises testing the sample for the presence of adipsin (complement factor D), Ab42 and EL-10.

Abstract: A method of diagnosing tuberculosis (TB) disease and distinguishing between active TB and latent TB infection in a subject is described herein. A sample from the subject is stimulated with at least one Mycobacterium tuberculosis (M.tb) infection phase-dependent antigen selected from Rv0081, Rv2032, Rv1737c, Rv2389c, Rv0867c, TB18.2, Rv2099c, Rv1733c, M.tb PPD, PHA and ESAT-6/CFP-10 and the presence of at least one host marker in the sample is detected, the host marker being selected from EGF, TGF-?, TNF-?, VEGF, RANTES, IL-12(p40), IL-12(p70), IL-10, IP-10, IFN-?2, fractalkine, IFN-?, IL-13, IL-1Ra, IL-3, IL-4, IL-5, MIP-1?, ENA-78, BCA-1, TARC, X6-Ckine, eotaxin, eotaxin-2, SCF, APOA-1, APOE, HPALBN, HCF, Serum amyloid protein A (SAA), C-reactive protein (CRP), serum amyloid protein P (SAP), TIMP-1, MIP-1?, IL-6, GM-CSF, IL-1?, MMP-9, MMP-2, MCP-1, TRAIL, IL-15, IL-17F, IL-22, TNF-?, MCP-2 and MCP-4. Additional host markers may also be detected in an unstimulated sample from the subject.
