The emergence of multidrug-resistant tuberculosis (MDR-TB; defined as resistance to at least rifampicin and isoniazid) represents a growing threat to public health and economic growth. Never before in the history of mankind have more patients been affected by MDR-TB than is the case today. The World Health Organization reports that MDR-TB outcomes are poor despite staggeringly high management costs. Moreover, treatment is prolonged, adverse events are common, and the majority of affected patients do not receive adequate treatment. As MDR-TB strains are often resistant to one or more second-line anti-TB drugs, in-depth genotypic and phenotypic drug susceptibility testing is needed to construct personalised treatment regimens to improve treatment outcomes. For the first time in decades, the availability of novel drugs such as bedaquiline allow us to design potent and well-tolerated personalised MDR-TB treatment regimens based solely on oral drugs. In this article, we present management guidance to optimise the diagnosis, algorithm-based treatment, drug dosing and therapeutic drug monitoring, and the management of adverse events and comorbidities, associated with MDR-TB. We also discuss the role of surgery, physiotherapy, rehabilitation, palliative care and smoking cessation in patients with MDR-TB. We hope that incorporating these recommendations into patient care will be helpful in optimising treatment outcomes, and lead to more MDR-TB patients achieving a relapse-free cure.

Rationale: Multidrug-resistant tuberculosis (MDR-TB) is a major burden to public health in Europe. Reported treatment success rates are around 50% or less, and cure rates are even lower., Objectives: To document the management and treatment outcome in patients with MDR-TB in Europe., Methods: We performed a prospective cohort study, analyzing management and treatment outcomes stratified by incidence of patients with MDR-TB in Europe. Treatment outcomes were compared by World Health Organization and alternative simplified definitions by the Tuberculosis Network European Trialsgroup (TBNET)., Measurements and Main Results: A total of 380 patients with MDR-TB were recruited and followed up between 2010 and 2014 in 16 European countries. Patients in high-incidence countries compared with low-incidence countries were treated more frequently with standardized regimen (83.2% vs. 9.9%), had delayed treatment initiation (median, 111 vs. 28 d), developed more additional drug resistance (23% vs. 5.8%), and had increased mortality (9.4% vs. 1.9%). Only 20.1% of patients using pyrazinamide had proven susceptibility to the drug. Applying World Health Organization outcome definitions, frequency of cure (38.7% vs. 9.7%) was higher in high-incidence countries. Simplified outcome definitions that include 1 year of follow-up after the end of treatment showed similar frequency of relapse-free cure in low- (58.3%), intermediate- (55.8%), and high-incidence (57.1%) countries, but highest frequency of failure in high-incidence countries (24.1% vs. 14.6%)., Conclusions: Conventional standard MDR-TB treatment regimens resulted in a higher frequency of failure compared with individualized treatments. Overall, cure from MDR-TB is substantially more frequent than previously anticipated, and poorly reflected by World Health Organization outcome definitions.

Since 2015 a significant increase in tuberculosis cases is notified in Germany, mostly due to rising numbers of migrants connected to the recent refugee crisis. Because of the low incidence in previous years, knowledge on tuberculosis is more and more limited to specialized centers. However, lung specialist and healthcare workers of other fields have contact to an increasing number of tuberculosis patients. In this situation, guidance for the management of standard therapy and especially for uncommon situations will be essential. This new guideline on tuberculosis in adults gives recommendations on diagnosis, treatment, prevention and prophylaxis. It provides a comprehensive overview over the current knowledge, adapted to the specific situation in Germany. The German Central Committee against Tuberculosis (DZK e. V.) realized this guideline on behalf of the German Respiratory Society (DGP). A specific guideline for tuberculosis in the pediatrics field will be published separately. Compared to the former recommendations of the year 2012, microbiological diagnostics and therapeutic drug management were given own sections. Chapters about the treatment of drug-resistant tuberculosis, tuberculosis in people living with HIV and pharmacological management were extended. This revised guideline aims to be a useful tool for practitioners and other health care providers to deal with the recent challenges of tuberculosis treatment in Germany., Competing Interests: Interessenkonflikt: Siehe Interessenkonflikterklärung auf www.awmf.org, (© Georg Thieme Verlag KG Stuttgart · New York.)

Rationale: We evaluated whether treatment outcomes for patients with multidrug-resistant and extensively drug-resistant tuberculosis can be substantially improved when sufficient resources for personalizing medical care are available., Objectives: To describe the characteristics and outcomes of patients with pulmonary multidrug-resistant tuberculosis at the Otto Wagner Hospital in Vienna, Austria., Methods: We conducted a retrospective single-center study of patients initiated on treatment for multi-drug resistant tuberculosis between January 2003 and December 2012 at the Otto Wagner Hospital, Vienna, Austria. The records of patients with multidrug-resistant tuberculosis were reviewed for epidemiological, clinical, laboratory, treatment, and outcome data., Measurements and Main Results: Ninety patients with pulmonary multidrug-resistant tuberculosis were identified. The median age was 30 years (interquartile range, 26-37). All patients were of non-Austrian origin, and 70 (78%) came from former states of the Soviet Union. Thirty-nine (43%) patients had multidrug-resistant tuberculosis; 28 (31%) had additional bacillary resistance to at least one second-line injectable drug and 9 (10%) to a fluoroquinolone. Fourteen (16%) patients had extensively drug-resistant tuberculosis. Eighty-eight different drug combinations were used for the treatment of the 90 patients. Surgery was performed on 10 (11.1%) of the patients. Sixty-five (72.2%) patients had a successful treatment outcome, 8 (8.9%) defaulted, 3 (3.3%) died, 8 (8.9%) continued treatment in another country and their outcome was unknown, and 6 (6.7%) were still on therapy. None of the patients experienced treatment failure. Treatment outcomes for patients with extensively drug-resistant tuberculosis were similar to those of patients with multidrug-resistant tuberculosis., Conclusions: High rates of treatment success can be achieved in patients with multidrug-resistant and extensively drug-resistant tuberculosis when individually tailored treatment regimens can be provided in a high-resource setting.
