Pulmonary Tuberculosis

Keywords

pulmonary tuberculosis, isoniazid, arylamine N-acetyltransferase 2, pharmacogenomics, genetic polymorphisms, individualized medicine, drug-induced hepatotoxity

Brief summary

The purpose of this study is to elucidate whether the individualized medicine based on NAT2 gene polymorphism could improve the safety, efficacy and economical benefits of multi-drug therapy for the pulmonary tuberculosis with isoniazid.

Interventions

DRUGIsoniazid

Modified daily isoniazid dose : approx. 7.5 mg/kg, 5 mg/kg and 2.5 mg/kg for rapid, intermediate and slow acetylators, respectively

DRUGisoniazed

Conventional standard daily isoniazid dose : approx. 5 mg/kg b.w. for all

Design outcomes

Primary

MeasureTime frameDescription
The incidences of unfavorable events in two different treatment regimens based on the NAT2 gene polymorphism1\) the incidences of drug-induced liver injury associated with INH that occurred within 8 weeks of the treatments, and 2) the incidence of early treatment failure as indicated by a persistent positive culture or no improvement in chest radiographs at the 8th week

Secondary

MeasureTime frame
Other adversed events during the 8 weeks of the intensive phase of the anti-tuberculosis therapy

Countries

Japan
