Joint Statement (DZK, DGRh, DDG) on the Tuberculosis Risk with Treatment Using Novel Non-TNF-Alpha Biologicals.

BACKGROUND: While the risk of tuberculosis (TB) reactivation is adequately documented in relation to TNF-alpha inhibitors (TNFi), the question of what the tuberculosis risk is for newer, non-TNF biologics (non-TNFi) has not been thoroughly addressed. METHODS: We conducted a systematic review of randomized phase 2 and phase 3 studies, and long-term extensions of same, published through March 2019. Of interest was information pertaining to screening and treating of latent tuberculosis (LTBI) in association with the use of 12 particular non-TNFi. Only rituximab was excluded. We searched MEDLINE and the ClinicalTrial.gov database for any and all candidate studies meeting these criteria. RESULTS: 677 citations were retrieved; 127 studies comprising a total of 34,293 patients who received non-TNFi were eligible for evaluation. Only 80 out of the 127 studies, or 63 %, captured active TB (or at least opportunistic diseases) as potential outcomes and 25 TB cases were reported. More than two thirds of publications (86/127, 68 %) mentioned LTBI screening prior to inclusion of study participants in the respective trial, whereas in only 4 studies LTBI screening was explicitly considered redundant. In 21 studies, patients with LTBI were generally excluded from the trials and in 42 out of the 127 trials, or 33 %, latently infected patients were reported to receive preventive therapy (PT) at least 3 weeks prior to non-TNFi treatment. CONCLUSIONS: The lack of information in many non-TNFi studies on the number of patients with LTBI who were either excluded prior to participating or had been offered PT hampers assessment of the actual TB risk when applying the novel biologics. Therefore, in case of insufficient information about drugs or drug classes, the existing recommendations of the German Central Committee against Tuberculosis should be applied in the same way as is done prior to administering TNFi. Well designed, long-term "real world" register studies on TB progression risk in relation to individual substances for IGRA-positive cases without prior or concomitant PT may help to reduce selection bias and to achieve valid conclusions in the future.

[The New WHO Guidelines for Rapid Diagnostics and Treatment of Drug-Resistant Tuberculosis Commented for Germany, Austria and Switzerland]. / Die neuen WHO-Empfehlungen für schnelle Diagnostik und Therapie resistenter Tuberkulose in Deutschland, Österreich und der Schweiz.

The increasing evidence has made it necessary to change international recommendations for the diagnosis and treatment of resistant tuberculosis repeatedly in the recent years. This year, the WHO has published comprehensive recommendations that take into account these developments. The current German tuberculosis guideline was published in 2017 with differing recommendations in some areas. Here the new WHO recommendations of 2020 for rapid diagnosis and therapy of resistant tuberculosis are summarized and the relevant differences are commented for Germany, Austria and Switzerland. A complete re-evaluation of the literature is currently taking place by updating the German-language AWMF 2k guidelines.

Recommendations of the German Central Committee against Tuberculosis (DZK) and the German Respiratory Society (DGP) for the Diagnosis and Treatment of Non-tuberculous Mycobacterioses.

Non-tuberculous mycobacterioses comprise a group of diseases caused by mycobacteria which do not belong to the Mycobacterium (M.) tuberculosis-complex and are not ascribed to M. leprae. These mycobacteria are characterized by a broad variety as to environmental distribution and adaptation. Some of the species may cause specific diseases, especially in patients with underlying immunosuppressive diseases, chronic pulmonary diseases or genetic predisposition, respectively. Worldwide, a rising prevalence and significance of non-tuberculous mycobacterioses is recognized. The present recommendations summarise current aspects of epidemiology, pathogenesis, clinical aspects, diagnostics - especially microbiological methods including susceptibility testing -, and specific treatment for the most relevant species. Diagnosis and treatment of non-tuberculous mycobacterioses during childhood and in HIV-infected individuals are described in separate chapters.

[Management of Adult Community-acquired Pneumonia and Prevention - Update 2016]. / Behandlung von erwachsenen Patienten mit ambulant erworbener Pneumonie und Prävention - Update 2016.

The present guideline provides a new and updated concept of treatment and prevention of adult patients with community-acquired pneumonia. It replaces the previous guideline dating from 2009.The guideline was worked out and agreed on following the standards of methodology of a S3-guideline. This includes a systematic literature search and grading, a structured discussion of recommendations supported by the literature as well as the declaration and assessment of potential conflicts of interests.The guideline has a focus on specific clinical circumstances, an update on severity assessment, and includes recommendations for an individualized selection of antimicrobial treatment as well as primary and secondary prevention.

[New drugs for treatment of tuberculosis]. / Neue Medikamente zur Behandlung der Tuberkulose.

New effective drugs for the treatment of tuberculosis (TB) are necessary for two main reasons: firstly, it would be desirable to reduce the duration of TB treatment from 6 to 4 months and secondly, new drugs are urgently needed for the treatment of multidrug-resistant strains of Mycobacterium tuberculosis. For the first time since 1960 the two new drugs bedaquiline and delamanid were approved and licensed in 2014 for the treatment of multidrug-resistant M. tuberculosis; however, efforts to reduce the duration of treatment to 4 months using fluoroquinolones have not been successful. Further new drugs are currently in phase 2 and phase 3 studies; therefore, new treatment options can be expected within the next few years.

[Treatment of tuberculosis. Current standards]. / Therapie der Tuberkulose. Was ist gesichert?

The treatment of drug-sensitive tuberculosis consists of 2 months of isoniazid, rifampin, pyrazinamide and ethambutol, followed by 4 months of isoniazid and rifampin. These drugs are well tolerated and cure rate are above 95 %. In contrast the treatment of drug-resistent tuberculosis is difficult, mostly due to side effects of the drugs used under these circumstances. Therefore, any treatment of drug-resistant tuberculosis has to be done by experts.

[New Drugs for the Treatment of Multidrug-resistant Tuberculosis (MDR-TB)]. / Kurze Übersicht über neue Medikamente zur Therapie der multiresistenten Tuberkulose.

This article summarizes the state of development of new drugs for the treatment of multidrug-resistant tuberculosis. We focused on delamanid, bedaquiline, pretomanid, SQ 109 and sutezolid.

[Non Tuberculous Mycobacteria--a Short Review about Epidemiology, Diagnosis and Treatment]. / Nichttuberkulöse Mykobakterien--eine kurze Übersicht zur Epidemiologie, Diagnostik und Therapie.

Non tuberculous mycobacterial diseases are caused by mycobacteria other than M. tuberculosis complex. NTM are found in the environment and are not transmitted from humans to humans. Infection occurs by the inhalation of dust or aerosols. The finding of NTM is not equal to a diagnosis of active disease. For the diagnosis of active disease well defined clinical and microbiological criteria have to be fulfilled. Gold standard is the detection of NTM by culture, in the case of pulmonary NTM at least two times. There is no established susceptibility testing. Treatment mostly consists of three drugs, given for up to 24 months.

[Informations and recommendations of the German Respiratory Society and the Paul-Ehrlich-Society for chemotherapy concerning the outbreak of influenza A(H7N9) virus infections in humans]. / Informationen und Empfehlungen der Deutschen Gesellschaft für Pneumologie und Beatmungsmedizin e.V. und der Paul-Ehrlich-Gesellschaft für Chemotherapie e.V. zum Ausbruch der Influenza A(H7N9)-Virus-Infektion beim Menschen.

In March 2013, the first cases of avian influenza virus infections in humans were reported by the authorities of the PR of China to the World Health Organization. This influenza A(H7N9) virus comprises genes of at least four different avian influenza viruses, some segments mimicking human-like influenza-signatures. Until 11 August, 2013 135 humans were infected, 44 (33%) died. The clinical course is characterized by fever, cough, gastrointestinal symptoms, lympho- and thrombopenia as well by the rapid onset of an acute respiratory distress syndrome in nearly 25% of the cases. Although human to human transmission may have occurred only in the context of three clusters, strict hygiene measures should be instituted and any suspect case should be reported to the local health authorities immediately. The detection of influenza A(H7N9) is based on real-time polymerase chain reaction (PCR). Antiviral treatment should be initiated as early as possible for suspect, probable or confirmed cases, even when 48 hours have passed after symptom onset. At present the future development of this epidemic cannot be predicted.
