The emergence of antimicrobial resistance against Mycobacterium tuberculosis, the leading cause of mortality due to a single microbial pathogen worldwide, represents a growing threat to public health and economic growth. The global burden of multidrug-resistant tuberculosis (MDR-TB) has recently increased by an annual rate of more than 20%. According to the World Health Organization approximately only half of all patients treated for MDR-TB achieved a successful outcome. ⋯ Phenotypic drug resistance can now often, but with variable sensitivity, be predicted by molecular drug susceptibility testing based on whole genome sequencing, which in the future could become an affordable method for the guidance of treatment decisions, especially in high-burden/resource-limited settings. More recently, MDR-TB treatment outcomes have dramatically improved with the use of bedaquiline-based regimens. Ongoing clinical trials with novel and repurposed drugs will potentially further improve cure-rates, and may substantially decrease the duration of MDR-TB treatment necessary to achieve relapse-free cure.

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a common presentation to emergency departments (ED) but data regarding its epidemiology and outcomes are scarce. We describe the epidemiology, clinical features, treatment and outcome of patients treated for AECOPD in ED. ⋯ Patients treated in ED for AECOPD commonly arrive by ambulance, have a high admission rate and significant in-hospital mortality. Compliance with evidence-based treatments in ED is suboptimal affording an opportunity to improve care and potentially outcomes.
