ABSTRACT
Objective To investigate the effects of different liver protective drugs on preventing liver injury induced by anti-tuberculosis drugs. Methods Retrospective analysis was made on 355 patients with primary pulmonary tuberculosis during intensified time. The patients received silibinon and bicyclol to prevent liver injury. 82 patients with TB were treated as control group during the same time. Results The number of patients with liver injury in silibinon group and bicyclol group were 16 cases (14.7%) and 55 cases (22.4%) respectively. The number of control group with liver injury was 9 cases (11.0%) (χ2 = 3.627,P > 0.05). The liver injuries within 4 weeks were mainly counted in. There is no difference between intervention and control groups(χ2 = 0.414,P > 0.05). There is no difference between three groups in liver injury degree (U = 0.288,P> 0.05). Conclusion Without high risk factors, anti-inflammatory and enzyme reduction drugs have no significant protective effects on liver injury caused by anti-tuberculosis drugs.
