BACKGROUND: Glutathione S-transferase (GST), together with other drug-metabolizing enzymes (N-acetyltransferase and cytochrome P450), plays a crucial role in the metabolism of isoniazid (isonicotinic acid hydrazide). Among five isoforms of GST, GSTM1, and GSTT1 had been proved to involve in isoniazid metabolism. AIM: We aimed to investigate association between GST deletion and hepatic injury in the Indonesian population. METHODS: This is a cross-sectional study. The total participants' number

Detection for GSTM1 and GSTT1 deletion performed with the polymerase chain reaction technique using internal standard β-globin. Data analysis performed with the Chi-square test. RESULTS: The proportion of GSTM1 null was 71.4% whereas the GSTT1 null was 34.3%. The proportion of combined GSTM1 null and GSTT1 null was 22.9%. There was no significant difference in liver damage incidence between GSTM1 null and wild-type (p > 0.005). There was also no significant difference in liver damage incidence between GSTT1 null and wild-type (p > 0.005). CONCLUSIONS: Neither GSTM1 nor GSTT1 deletion proved to be associated with liver injury regarding antituberculosis use.
