Webb3 juli 2024 · Isoniazid (INH) is inactivated to acetyl INH by N-acetyltransferase (NAT) enzymes. MTB: Mycobacterium tuberculosis. NAT2 in humans is responsible for the inactivation of INH through acetylation similar to NAT of MTB 9. The NAT2 of human has long been identified as drug metabolising enzyme. Webb1 okt. 2024 · INH concentration (INH plus acetyl INH and their ratio) in hair samples was measured. We used Bland-Altman plots to examine agreement between adherence measures, and calculated the area under the receiver operator curve (ARUC) to determine if INH hair concentration predicted optimal MEMS-measured adherence (≥90%).
