[Characteristics and treatment outcomes of INH-resistant or RFP-resistant tuberculosis].
As an effective regimen for isoniazid-resistant but rifampicin-susceptible tuberculosis (INHr-TB), the use of a 6-month three or four-drug treatment regimen including refampicin (or rifampin) and pyrazinamide has been recommended by many experts of the world. On the other hand, treatment regimen for rifampicin-resistant but isoniazide-susceptible tuberculosis (RFPr-TB) has not been well established because of the small number of such patients. In Japan the standard regimen has not been established even for INHr-TB, and the treatment has been done by each physician on the empirical bases. ⋯ For INHr-TB, even when PZA can't be used because of adverse effects or resistance, 3 or 4 susceptible drugs regimens including RFP for 12 months were effective. For RFPr-TB, the treatment with 4 or more susceptible drugs for 20 months after sputum culture conversion might be adequate.
