- 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.

- The World Health Organization recommends standardised treatment durations for patients with tuberculosis (TB). We identified and validated a host-RNA signature as a biomarker for individualised therapy durations for patients with drug-susceptible (DS)- and multidrug-resistant (MDR)-TB.MethodsAdult patients with pulmonary TB were prospectively enrolled into five independent cohorts in Germany and Romania. Clinical and microbiological data and whole blood for RNA transcriptomic analysis were collected at pre-defined time points throughout therapy. Treatment outcomes were ascertained by TBnet criteria (6-month culture status/1-year follow-up). A whole-blood RNA therapy-end model was developed in a multistep process involving a machine-learning algorithm to identify hypothetical individual end-of-treatment time points.Results50 patients with DS-TB and 30 patients with MDR-TB were recruited in the German identification cohorts (DS-GIC and MDR-GIC, respectively); 28 patients with DS-TB and 32 patients with MDR-TB in the German validation cohorts (DS-GVC and MDR-GVC, respectively); and 52 patients with MDR-TB in the Romanian validation cohort (MDR-RVC). A 22-gene RNA model (TB22) that defined cure-associated end-of-therapy time points was derived from the DS- and MDR-GIC data. The TB22 model was superior to other published signatures to accurately predict clinical outcomes for patients in the DS-GVC (area under the curve 0.94, 95% CI 0.9–0.98) and suggests that cure may be achieved with shorter treatment durations for TB patients in the MDR-GIC (mean reduction 218.0 days, 34.2%; p<0.001), the MDR-GVC (mean reduction 211.0 days, 32.9%; p<0.001) and the MDR-RVC (mean reduction of 161.0 days, 23.4%; p=0.001).ConclusionBiomarker-guided management may substantially shorten the duration of therapy for many patients with MDR-TB.

- BACKGROUND: The potential association between the lung function status at baseline and TB treatment outcome has not been evaluated previously. We aimed to investigate the impact of lung function status at the time of TB diagnosis on treatment outcome in patients with pulmonary TB (PTB).METHODS: A retrospective cohort study on data from all consecutive patients with culture-confirmed PTB and available spirometry test results admitted during the year 2016 to the Regional anti-TB dispensary no.1 in Kharkiv, Ukraine.RESULTS: A total of 278 patients with PTB were included into the study. The rate of negative treatment outcome (failure or death) was higher in patients with restrictive and mixed lung dysfunction than in those with normal spirometry results (25.6% vs. 6.8%, P = 0.0007; 37.5% vs. 6.8%, P = 0.003, respectively). In a logistic regression model, restrictive lung disease and mixed-type lung disease were associated with negative treatment outcome (OR 4.19, 95% CI 1.60-13.28, P = 0.007 and OR 5.46, 95% CI 1.28-24.44, P = 0.02, respectively).CONCLUSIONS: Lung function at the time of diagnosis has an important impact on treatment outcomes in patients with PTB; the more severe the restriction in lung function the higher the likelihood of a negative treatment outcome.

Tidskriftsartikel (refereegranskat)abstract
- Rapid and accurate drug susceptibility testing (DST) is essential for the treatment of multi-and extensively drug-resistant tuberculosis (M/XDR-TB). We compared the utility of genotypic DST assays with phenotypic DST (pDST) using Bactec 960 MGIT or Lowenstein-Jensen to construct M/XDR-TB treatment regimens for a cohort of 25 consecutive M/XDR-TB patients and 15 possible anti-TB drugs. Genotypic DST results from Cepheid GeneXpert MTB/RIF (Xpert) and line probe assays (LPAs; Hain GenoType MTBDRplus 2.0 and MTBDRsl 2.0) and whole-genome sequencing (WGS) were translated into individual algorithmderived treatment regimens for each patient. We further analyzed if discrepancies between the various methods were due to flaws in the genotypic or phenotypic test using MIC results. Compared with pDST, the average agreement in the number of drugs prescribed in genotypic regimens ranged from just 49% (95% confidence interval [ CI], 39 to 59%) for Xpert and 63% (95% CI, 56 to 70%) for LPAs to 93% (95% CI, 88 to 98%) for WGS. Only the WGS regimens did not contain any drugs to which pDST showed resistance. Importantly, MIC testing revealed that pDST likely underestimated the true rate of resistance for key drugs (rifampin, levofloxacin, moxifloxacin, and kanamycin) because critical concentrations (CCs) were too high. WGS can be used to rule in resistance even in M/XDR strains with complex resistance patterns, but pDST for some drugs is still needed to confirm susceptibility and construct the final regimens. Some CCs for pDST need to be reexamined to avoid systematic false-susceptible results in low-level resistant isolates.

- Diagnosing pulmonary tuberculosis (TB) may be delayed until culture results become available.We ascertained the accuracy of a stepwise diagnostic algorithm for the rapid diagnosis of pulmonary TB by GeneXpert from sputum and/or bronchoalveolar lavage (BAL) followed by aMycobacterium tuberculosis-specific BAL ELISPOT assay in patients with a suspected diagnosis of pulmonary TB at a clinical referral centre in Germany.Among 166 patients with a presumptive diagnosis of pulmonary TB, 81 cases were confirmed byM. tuberculosisculture from sputum and/or BAL. In 66 out of 81 (81.5%) cases, patients initially hadM. tuberculosisdetected by GeneXpert from sputum; in addition, six out of 81 (7.4%) cases were diagnosed by GeneXpert on BAL fluid (together 72 out of 81 (88.9%) patients). Out of the remaining nine patients with negative GeneXpert results from sputum and BAL, BAL ELISPOT identified eight patients with culture-confirmed TB correctly (median time to culture positivity 26 days). At a cut-off of >4000 early secretory antigenic target-6- or culture filtrate protein-10-specific interferon-γ-producing lymphocytes per 1 000 0000 lymphocytes, the specificity of the BAL ELISPOT for active TB was 97%.In low TB incidence countries, nearly all patients with active pulmonary TB can be identified within the first few days of clinical presentation using a stepwise strategy with GeneXpert and BAL ELISPOT.

Forskningsöversikt (refereegranskat)abstract
- According to the World Health Organization (WHO), tuberculosis is the leading cause of death attributed to a single microbial pathogen worldwide. In addition to the large number of patients affected by tuberculosis, the emergence of Mycobacterium tuberculosis drug-resistance is complicating tuberculosis control in many high-burden countries. During the past 5years, the global number of patients identified with multidrug-resistant tuberculosis (MDR-TB), defined as bacillary resistance at least against rifampicin and isoniazid, the two most active drugs in a treatment regimen, has increased by more than 20% annually. Today we experience a historical peak in the number of patients affected by MDR-TB. The management of MDR-TB is characterized by delayed diagnosis, uncertainty of the extent of bacillary drug-resistance, imprecise standardized drug regimens and dosages, very long duration of therapy and high frequency of adverse events which all translate into a poor prognosis for many of the affected patients. Major scientific and technological advances in recent years provide new perspectives through treatment regimens tailor-made to individual needs. Where available, such personalized treatment has major implications on the treatment outcomes of patients with MDR-TB. The challenge now is to bring these adances to those patients that need them most.

- The United Nations Millennium Development Goal of reversing the global spread of tuberculosis by 2015 has been offset by the rampant re-emergence of drug-resistant tuberculosis, in particular fluoroquinolone-resistant multidrug-resistant and extensively drug-resistant tuberculosis. After decades of quiescence in the development of antituberculosis medications, bedaquiline and delamanid have been conditionally approved for the treatment of drug-resistant tuberculosis, while several other novel compounds (AZD5847, PA-824, SQ109 and sutezolid) have been evaluated in phase II clinical trials. Before novel drugs can find their place in the battle against drug-resistant tuberculosis, linezolid has been compassionately used with success in the treatment of fluoroquinolone-resistant multidrug-resistant tuberculosis. This review largely discusses six novel drugs that have been evaluated in phase II and III clinical trials, with focus on the clinical evidence for efficacy and safety, potential drug interactions, and prospect for using multiple novel drugs in new regimens.

Tidskriftsartikel (refereegranskat)abstract
- Systemic endemic mycoses cause high rates of morbidity and mortality in certain regions of the world and the real impact on global health is not well understood. Diagnosis and management remain challenging, especially in low-prevalence settings, where disease awareness is lacking. The main challenges include the variability of clinical presentation, the fastidious and slow-growing nature of the fungal pathogens, the paucity of diagnostic tests, and the lack of options and toxicity of antifungal drugs. Coccidioidomycosis and paracoccidioidomycosis are restricted to the Americas only, and while histoplasmosis and blastomycosis also occur predominantly in the Americas, these mycoses have also been reported on other continents, especially in sub-Saharan Africa. Talaromycosis is endemic in tropical and subtropical regions in South-East Asia and southern China. Systemic endemic mycoses causing pulmonary disease are usually acquired via the airborne route by inhalation of fungal spores. Infections can range from asymptomatic or mild with flu-like illnesses to severe pulmonary or disseminated diseases. Skin involvement is frequent in patients with paracoccidioidomycosis, blastomycosis, sporotrichosis, and talaromycosis and manifests as localized lesions or diffuse nodules in disseminated disease, but can also occur with other endemic mycoses. Culture and/or characteristic histopathology from clinical samples is the diagnostic standard for endemic mycoses. Immunological assays are often not available for the diagnosis of most endemic mycoses and molecular amplification methods for the detection of fungal nucleic acids are not standardized at present. The first-line treatment for mild to moderate histoplasmosis, paracoccidioidomycosis, blastomycosis, sporotrichosis, and talaromycosis is itraconazole. Severe illness is treated with amphotericin B. Patients with severe coccidioidomycosis should receive fluconazole. Treatment duration depends on the specific endemic mycosis, the severity of disease, and the immune status of the patient, ranging between 6 weeks and lifelong treatment.

- Chronic respiratory infectious diseases are causing high rates of morbidity and mortality worldwide. Tuberculosis, a major cause of chronic pulmonary infection, is currently responsible for approximately 1.5 million deaths per year. Although important advances in the fight against tuberculosis have been made, the progress towards eradication of this disease is being challenged by the dramatic increase in multidrug-resistant bacilli. Nontuberculous mycobacteria causing pulmonary disease and chronic pulmonary aspergillosis are emerging infectious diseases. In contrast to other infectious diseases, chronic respiratory infections share the trait of having highly variable treatment outcomes despite longstanding antimicrobial therapy. Recent scientific progress indicates that medicine is presently at a transition stage from programmatic to personalized management. We explain current state-of-the-art management concepts of chronic pulmonary infectious diseases as well as the underlying methods for therapeutic decisions and their implications for personalized medicine. Furthermore, we describe promising biomarkers and techniques with the potential to serve future individual treatment concepts in this field of difficult-to-treat patients. These include candidate markers to improve individual risk assessment for disease development, the design of tailor-made drug therapy regimens, and individualized biomarker-guided therapy duration to achieve relapse-free cure. In addition, the use of therapeutic drug monitoring to reach optimal drug dosing with the smallest rate of adverse events as well as candidate agents for future host-directed therapies are described. Taken together, personalized medicine will provide opportunities to substantially improve the management and treatment outcome of difficult-to-treat patients with chronic respiratory infections.

- In Deutschland ist seit 2015 ein deutlicher Anstieg der gemeldeten Tuberkulosefälle zu verzeichnen. Zurückzuführen ist dieser vor allem auf die aktuell vermehrte Migration. Durch die niedrige Inzidenz in den vorhergehenden Jahren konzentriert sich die Erfahrung im Umgang mit Tuberkulose immer mehr auf spezialisierte Zentren. Pneumologen wie auch andere Fachbereiche sind nun aber wieder häufiger an der Behandlung einer Tuberkulose beteiligt, sodass Fachwissen zur Standardtherapie wie auch zu selteneren Therapiesituationen benötigt wird. Die aktuelle Leitlinie zur Diagnostik und Therapie, einschließlich Chemoprävention und -prophylaxe im Erwachsenenalter fasst den derzeitigen Wissensstand zusammen und passt die Empfehlungen an die Situation in Deutschland an. Realisiert wurde die AWMF S2k-Leitlinie durch das Deutsche Zentralkomitee zur Bekämpfung der Tuberkulose e. V. (DZK) im Auftrag der Deutschen Gesellschaft für Pneumologie und Beatmungsmedizin e. V. (DGP). Zur Behandlung der Tuberkulose im pädiatrischen Bereich wird in Kürze eine eigenständige Leitlinie der entsprechenden Fachgesellschaften veröffentlicht. Im Vergleich zu den Empfehlungen von 2012 sind eigenständige Kapitel zur Labordiagnostik und zum therapeutischen Medikamentenmanagement entstanden. Die Kapitel Mehrfachresistenzen gegen Medikamente der Standardtherapie, HIV-Koinfektion und die Übersicht der Arzneimittel wurden erweitert. Die umfangreiche Überarbeitung der Empfehlungen soll Ärzten und auch anderen Beschäftigten im Gesundheitswesen helfen, den aktuellen Herausforderungen im Umgang mit dem selten gewordenen Tuberkuloseerreger zu begegnen.
