Extract
Multidrug-resistant (MDR) tuberculosis (TB) (resistance to at least isoniazid and rifampicin), with >480 000 cases in 2013, 10% of them being affected by extensively drug-resistant (XDR)-TB (MDR-TB with additional resistance to any fluoroquinolone, and to injectable second-line drugs (SLDs) (capreomycin, kanamycin or amikacin)), continues to represent a real threat to TB control [1–4]. In some high MDR-TB burden countries, the prevalence of MDR-TB among new cases exceeds 20% and among retreatment cases, reaches almost 50% [1, 5].
Abstract
The classification of the anti-TB drugs should probably be modified to optimise the use old and new compoundshttp://ow.ly/QbDSP
