High-dose isoniazid therapy for isoniazid-resistant murine Mycobacterium tuberculosis infection.
The use of isoniazid (INH) for the treatment of INH-resistant Mycobacterium tuberculosis infection has been controversial. The purpose of the present studies was to determine if there is a dose response with INH for INH-susceptible M. tuberculosis Erdman (ATCC 35801), and whether high-dose INH (100 mg/kg of body weight) was more effective than standard-dose INH (25 mg/kg) for therapy of tubercu...
متن کاملIsoniazid-induced transient high-level resistance in Mycobacterium tuberculosis.
An American Type Culture Collection reference strain and eight clinical strains of Mycobacterium tuberculosis, all of which were susceptible to isoniazid (INH) (mean MIC, 0.06 mg/liter) and negative for the Ser315Thr katG mutation, were left in their BACTEC 12B vials (for use with the BACTEC 460-TB method) containing 0.1 mg of INH per liter for periods of up to 28 days after the completion of t...
متن کاملDevelopment of multidrug resistance during treatment of isoniazid-resistant tuberculosis.
Several treatment regimens have been recommended for the treatment of isoniazid-resistant tuberculosis (TB). However, an optimal regimen and duration for this treatment remains a matter of some controversy. Here, we would like to share our experience in a case of pulmonary TB with acquired multidrug resistance, during a 12-month treatment of isoniazid-resistant TB with rifampin and ethambutol, ...
متن کاملResistance to rifampicin and isoniazid in strains of Mycobacterium tuberculosis.
Drug susceptibility studies on strains of Mycobacterium tuberculosis isolated from widely different populations of patients and tested by two different techniques indicated that all 55 strains resistant to rifampicin were also resistant to isoniazid, while many strains resistant to isoniazid were found to be susceptible to rifampicin. This observation, which has as yet unknown laboratory and cl...
متن کامل[Isoniazid and rifampicin resistance and prior treatment for tuberculosis].
A case-control study in Rio de Janeiro in 1994 included 552 patients with a positive culture for Mycobacterium tuberculosis and reported a 1.8% resistance rate to rifampicin and isoniazid. Prior treatment for tuberculosis (the exposure factor) was associated with resistance. The binomial proportion was used to test the hypothesis of no dependence between the observed associations based on prior...
