The changes of the ratio of T helper 17 and regulatory T cells in the peripheral blood of patients with anti-tuberculosis drug-induced liver injury and its significance / 中华传染病杂志

ABSTRACT

Objective To observe the changes of the peripheral blood T helper (Th)17 cells/regulatory T cells (Treg) ratio in patients with anti‐tuberculosis drug‐induced liver injury ,and to explore the relationship between Th17/Treg ratio and liver function . Methods Ninety inpatients with the diagnosis of secondary pulmonary tuberculosis (TB) from Affiliated Hospital of Zunyi Medical College from Feb .2013 to Mar .2015 were included in this study .All these patients had normal base line liver function .After 2 weeks of anti‐TB chemotherapy ,21 patients with alanine transaminase (ALT) and/or aspartate aminotransferase (AST) ≥2 × upper limit of normal (ULN) were defined as TB with liver injure group ,the other 69 patients with ALT and/or AST 0 .05) .The Th17 levels in TB with liver injured group ([2 .522 ± 0 .388]/mL vs [2 .075 ± 0 .369]/mL ,t=3 .633 ,P0 .05) .The Th17 level and Th17/Treg ratio in TB with liver injured group were significantly higher than those in TB with non‐liver injured group (t= 2 .203 , P0 .05) .Conclusion The changes of Th17/Treg ratio are related with anti‐TB drug‐induced liver injury in patients with secondary pulmonary tuberculosis .
