IL17A and tuberculosis: IL-17 mRNA expression levels in PBMCs were significantly higher in patients with HBV-conditions than in the controls. PBMCs IL-17 mRNA and the serum IL-17 protein were significantly higher in patients in higher Child–Pugh (B or C) than in lower scores. Serum IL-17 levels correlated positively with TB, ALT, and Child score; and correlated inversely with albumin
