Background To date, few data on paediatric COVID-19 have been published, and most reports originate from China. This study aimed to capture key data on children and adolescents with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection across Europe to inform physicians and health-care service planning during the ongoing pandemic. Methods This multicentre cohort study involved 82 participating health-care institutions across 25 European countries, using a well established research network-the Paediatric Tuberculosis Network European Trials Group (ptbnet)-that mainly comprises paediatric infectious diseases specialists and paediatric pulmonologists. We included all individuals aged 18 years or younger with confirmed SARS-CoV-2 infection, detected at any anatomical site by RT-PCR, between April 1 and April 24, 2020, during the initial peak of the European COVID-19 pandemic. We explored factors associated with need for intensive care unit (ICU) admission and initiation of drug treatment for COVID-19 using univariable analysis, and applied multivariable logistic regression with backwards stepwise analysis to further explore those factors significantly associated with ICU admission. Findings 582 individuals with PCR-confirmed SARS-CoV-2 infection were included, with a median age of 5•0 years (IQR 0•5-12•0) and a sex ratio of 1•15 males per female. 145 (25%) had pre-existing medical conditions. 363 (62%) individuals were admitted to hospital. 48 (8%) individuals required ICU admission, 25 (4%) mechanical ventilation (median duration 7 days, IQR 2-11, range 1-34), 19 (3%) inotropic support, and one (<1%) extracorporeal membrane oxygenation. Significant risk factors for requiring ICU admission in multivariable analyses were being younger than 1 month (odds ratio 5•06, 95% CI 1•72-14•87; p=0•0035), male sex (2•12, 1•06-4•21; p=0•033), pre-existing medical conditions (3•27, 1•67-6•42; p=0•0015), and presence of lower respiratory tract infection signs or symptoms at presentation (10•46, 5•16-21•23; p<0•0001). The most frequently used drug with antiviral activity was hydroxychloroquine (40 [7%] patients), followed by remdesivir (17 [3%] patients), lopinavir-ritonavir (six [1%] patients), and oseltamivir (three [1%] patients). Immunomodulatory medication used included corticosteroids (22 [4%] patients), intravenous immunoglobulin (seven [1%] patients), tocilizumab (four [1%] patients), anakinra (three [1%] patients), and siltuximab (one [<1%] patient). Four children died (case-fatality rate 0•69%, 95% CI 0•20-1•82); at study end, the remaining 578 were alive and only 25 (4%) were still symptomatic or requiring respiratory support. Interpretation COVID-19 is generally a mild disease in children, including infants. However, a small proportion develop severe disease requiring ICU admission and prolonged ventilation, although fatal outcome is overall rare. The data also reflect the current uncertainties regarding specific treatment options, highlighting that additional data on antiviral and immunomodulatory drugs...

ZusammenfassungDie Deutsche Gesellschaft für Pneumologie hat die AWMFS1-Leitlinie Post-COVID/Long-COVID initiiert. In einem breiten interdisziplinären Ansatz wurde diese S1-Leitlinie basierend auf dem aktuellen Wissensstand gestaltet.Die klinische Empfehlung beschreibt die aktuellen Post-COVID/Long-COVID-Symptome, diagnostische Ansätze und Therapien.Neben der allgemeinen und konsentierten Einführung wurde ein fachspezifischer Zugang gewählt, der den aktuellen Wissensstand zusammenfasst.Die Leitlinie hat einen expilzit praktischen Anspruch und wird basierend auf dem aktuellen Wissenszugewinn vom Autorenteam stetig weiterentwickelt und adaptiert.

BackgroundThe lower airways harbor a community of bacterial species which is altered in asthma.ObjectivesWe examined whether the lower airway microbiota were related to measures of asthma severity.MethodsWe prospectively recruited 26 severe asthma, 18 non-severe asthma and 12 healthy subjects. DNA was extracted from induced sputum and PCR amplification of the V3-V5 region of bacterial 16S rRNA gene was performed.ResultsWe obtained 138,218 high quality sequences which were rarefied at 133 sequences/sample. Twenty OTUs had sequences ≥1% of total. There were marked differences in the distribution of Phyla between groups (P = 2.8x10-118). Bacteroidetes and Fusobacteria were reduced in non-severe and severe asthmatic groups. Proteobacteria were more common in non-severe asthmatics compared to controls (OR = 2.26; 95% CI = 1.94–2.64) and Firmicutes were increased in severe asthmatics compared to controls (OR = 2.15; 95%CI = 1.89–2.45). Streptococcal OTUs amongst the Firmicutes were associated with recent onset asthma, rhinosinusitis and sputum eosinophilia.ConclusionsSputum microbiota in severe asthma differs from healthy controls and non-severe asthmatics, and is characterized by the presence of Streptococcus spp with eosinophilia. Whether these organisms are causative for the pathophysiology of asthma remains to be determined.

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.

Small intestinal bacterial overgrowth in cirrhotic patients is common and associated with systemic endotoxemia. The clinical relevance of this association remains to be defined.
