CD8A and tuberculosis: Pyrazinamide clearance was shown to be inversely correlated to chronic cellular immune activation in HIV‐TB patients in Botswana.44 We did not measure human leucocyte antigen‐DR expression on CD8 T cells in our study and, even though hospitalized patients and specifically patients who died had higher C‐reactive protein and procalcitonin, there was no significant correlation between pyrazinamide exposure and either of these markers.
