RT Journal Article SR Electronic T1 Regimens to treat multidrug-resistant tuberculosis: past, present and future perspectives JF European Respiratory Review JO EUROPEAN RESPIRATORY REVIEW FD European Respiratory Society SP 190035 DO 10.1183/16000617.0035-2019 VO 28 IS 152 A1 Pontali, Emanuele A1 Raviglione, Mario C. A1 Migliori, Giovanni Battista A1 YR 2019 UL http://err.ersjournals.com/content/28/152/190035.abstract AB Over the past few decades, treatment of multidrug-resistant (MDR)/extensively drug-resistant (XDR) tuberculosis (TB) has been challenging because of its prolonged duration (up to 20–24 months), toxicity, costs and sub-optimal outcomes.After over 40 years of neglect, two new drugs (bedaquiline and delamanid) have been made available to manage difficult-to-treat MDR-/XDR-TB cases. World Health Organization (WHO) guidelines published in March 2019 endorsed the possibility of treating MDR-TB patients with a full oral regimen, following previous guidelines published in 2016 which launched a shorter regimen lasting 9–10 months.The objectives of this article are to review the main achievements in MDR-TB treatment through the description of the existing WHO strategies, to discuss the main ongoing trials and to shed light on potential future scenarios and revised definitions necessary to manage drug-resistant TB.The article reviews the evolution of the strategies and regimens to manage drug-resistant tuberculosis, opening a window on future perspectives. http://bit.ly/2Q1Rhx0
