Abstract: AIM: To understand the Occurrence mechanism of the anti-tuberculosis drug-induced fatty liver and drug-induced liver injury (DILI). METHODS: 200 tuberculosis(TB)patients were received,liver function and serum lipid were monitored before and after anti-TB treatment,underwent X-ray computer tomography scan fatty liver before and complete treatment. The experimental data were treated statistically.RESULTS: :The incidence of fatty liver was 28.00% (56/200) and the incidence of DILI was 32.00% (64/200) after treatment. The serum ALT, AST levels after treatment were higher than those before treatment ( P<0.05). The ALT levels after treatment in first, second, third months,AST levels after treatment in first, second, third ,fourth months was the most statistically significant difference than before treatment (P<0.01). TG, HDL-C, LDL-C, apoB levels were significantly higher than that before treatment (P<0.05). The TG levels after treatment in second,third,fourth months, LDL-C levels after treatment in third, fouth months, apoB in first, second, third,fourth,fifth months was the most significant than before treatment (P<0.01). The increase　of ALT, AST levels in the serum were significantly postive correlation with the levels of TG, apoB, HDL-C, LDL-C (P<0.05,P<0.01).CONCLUSION: The formation of fatty liver suggests DILI has undergone in anti-tuberculosis treatment. To strengthen the monitoring of blood lipid indexes can, reduce the occurrence of DILI, prevent the formation of fatty liver, ensure the implementation scheme in treatment of tuberculosis.
