Multidrug-Resistant Tuberculosis (TB) Resistant to Fluoroquinolones and Streptomycin but Susceptible to Second-Line Injection Therapy Has a Better Prognosis than Extensively Drug-Resistant TB

摘要

Multidrug-resistant tuberculosis (TB) strains resistant to the fluoroquinolones and streptomycin but susceptible to second-line injection treatment would not be defined as extensively drug-resistant TB. In a cohort of 174 patients with multidrug-resistant TB, we demonstrated that 12 patients with multidrug-resistant TB strains resistant to the fluoroquinolones and streptomycin had significantly better initial and long-term outcomes, compared with 10 patients with extensively drug-resistant TB.
