Abstract
IFN-g release assays (IGRAs) have suboptimal sensitivity for detection of Mycobacterium tuberculosis
(Mtb) infection and cannot discriminate between tuberculosis (TB) patients and healthy -potentially Mtb
infected- contacts (HCs). In a case-control study, we determined T-cell phenotypes of IGRAs in TB patients
(n ¼ 20) and HCs (n ¼ 20) from Ghana. CD27 expression of T-cells was significantly lower in TB
patients as compared to HCs independent from Mtb-specificity. CD27 expression discriminated both
study groups - including TB patients with low or indeterminate IGRA results - effectively. We conclude
that CD27 is a promising biomarker for diagnosis of TB patients with inconclusive IGRA results.
