- Mycobacterium tuberculosis infection that is resistant to both first-line drugs, isoniazid and rifampin
Classification
- Multidrug resistant tuberculosis (MDR-TB)): resistance to isoniazid and rifampicin
- Extensively drug-resistant tuberculosis (XDR-TB): resistance to at least isoniazid and rifampicin, and to any fluoroquinolone, and to any of the three second-line injectables
- Totally drug-resistant tuberculosis (TDR-TB): not well-defined
Management
- 8 months of an intensive four-drug regimen that includes any four drugs to which it is susceptible, in order of preference:
- Any first-line agents to which it is still susceptible
- A fluoroquinolone (except ciprofloxacin)
- An injectable: kanamycin, or other parenteral agent
- Other second-line agents, starting with ethionamide
- Followed by 12 months of a less intensive regimen (at least three effective drugs), for a total of at least 20 months
