High-dose isoniazid for TB with low-to-moderate isoniazid resistance after 1 week of treatment
To evaluate the effect of high-dose isoniazid in patients with isoniazid-resistant TB by its bactericidal
activity after 1 or more weeks of treatment.Using the rapid direct method of phenotypic drug susceptibility testing, we screened persons with positive sputum microscopy results and genotypic drug resistance for isoniazid resistance.Those with no growth at a critical concentration of 2.0 mg/L were invited to participate in a trial of high-dose isoniazid monotherapy lasting 6 days. After 3 days of no treatment, patients received isoniazid 15 mg/kg and were followed with serial quantitative sputum cultures from Days 0 to
