The correlation study between PZA and anti-tuberculosis drug-induced liver injury / 实用医学杂志

ABSTRACT

Objective To study the correlation of PAZ with anti-tuberculosis treatment regimen and drug-induced liver injury in tuberculosis patients with HBV-DNA positive in order to provide an optimized treatment regimen. Methods from Jan 2013 to Dec 2014, 199 pulmonary tuberculosis with HBV-DNA positive patients and 103 pulmonary tuberculosis patients without HBV in our hospital were collected. They were assigned as follows122 cases were anti tuberculosis treatment with antiviral therapy,64 cases were A(HRZE),58 cases were B (HRE). 77 cases were anti tuberculosis treatment but not antiviral therapy , 41 cases were C (HRZE), 36 cases were D(HRE) and 103 patients without HBV were E (HRZE, the contrast group). We had observed the liver injury for 2 months after the treatment. Results 1.Incidence of liver injury was 34.38% in group A , higher than the cases in group B(20.69%,P > 0.05). 2.Incidence of liver injury in group C was apparently higher than in group D (73.17% vs. 30.56%,P 0.05)4.Incidence of liver injury in group A was lower than group C (34.38% vs. 73.17%,P 0.05). Conclusion Although anti tuberculosis treatment combined with antiviral therapy can be partially reduce the incidence of liver injury and relieve the severity of liver injury in tuberculosis patients infected with HBV , but PZA toxicity to hepatocytes is a major risk factor for liver injury , and we need to change the treatment plan to reduce the occurrence of liver injury.
