Management of multidrug-resistant TB : novel treatments and their expansion to low resource settings

This article received no specific funding. JL is supported by the Wellcome Trust as a clinical PhD fellow [grant number 109105/Z/15/Z].Despite overall progress in global TB control, the rising burden ofmultidrug-resistant TB (MDR-TB) threatens to undermine efforts to end theworldwide epidemic. Of the 27 countries classified as high burden for MDR-TB, 17 are in 'low' or 'low-middle' income countries. Shorter, all oral and less toxic multidrug combinations are required to improve treatment outcomes in these settings. Suitability for safe co-administration with HIV drugs is also desirable. A range of strategies and several new drugs (including bedaquiline, delamanid and linezolid) are currently undergoing advanced clinical evaluations to define their roles in achieving these aims. However, several clinical questions and logistical challenges need to be overcome before these new MDR-TB treatments fulfil their potential.Publisher PDFPeer reviewe
