Central nervous system tuberculosis remains a clinical diagnostic challenge. The ex vivo Mycobacterium tuberculosis-specific enzyme-linked immunospot assay (ELISPOT) is a novel assay for the rapid detection of M. tuberculosis-specific T-lymphocytes in the peripheral blood. However, when performed on peripheral blood, this assay cannot distinguish between active tuberculosis or latent tuberculosis infection. On the assumption that M. tuberculosis-specific T-lymphocytes migrate to sites of infection, we were able to demonstrate high levels of M. tuberculosis-specific cells by ELISPOT in the cerebrospinal fluid of a patient with tuberculous meningitis and intracerebral tuberculoma four weeks before cerebrospinal fluid culture became positive for M. tuberculosis by culture.

Purpose: This study investigates the care provision and the role of infectious disease (ID) specialists during the coronavirus disease-2019 (COVID-19) pandemic., Methods: A survey was conducted at German study sites participating in the Lean European Open Survey on SARS-CoV-2 infected patients (LEOSS). Hospitals certified by the German Society of Infectious diseases (DGI) were identified as ID centers. We compared care provision and the involvement of ID specialists between ID and non-ID hospitals. Then we applied a multivariable regression model to analyse how clinical ID care influenced the mortality of COVID-19 patients in the LEOSS cohort., Results: Of the 40 participating hospitals in the study, 35% (14/40) were identified as ID centers. Among those, clinical ID care structures were more commonly established, and ID specialists were always involved in pandemic management and the care of COVID-19 patients. Overall, 68% (27/40) of the hospitals involved ID specialists in the crisis management team, 78% (31/40) in normal inpatient care, and 80% (28/35) in intensive care. Multivariable analysis revealed that COVID-19 patients in ID centers had a lower mortality risk compared to those in non-ID centers (odds ratio: 0.61 (95% CI 0.40-0.93), p = 0.021)., Conclusion: ID specialists played a crucial role in pandemic management and inpatient care., Competing Interests: Declarations. Conflict of interest: On behalf of all authors, the corresponding author declares no conflict of interest. Ethics approval and consent to participate: The study was approved by the ethics committee of the Goethe University Frankfurt (department: medicine, No. 20–600) as well as by local ethics committees of participating sites, where required. Consent to participate for LEOSS was not required according to the EU General Data Protection Regulation due to the anonymous and retrospective data collection strategy. LEOSS was registered at the German Clinical Trails Register (DRKS, No. S00021145)., (© 2024. The Author(s).)

Introduction: Emergency department (ED) triage regarding infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is challenging. During the coronavirus disease 2019 (COVID-19) outbreak in Germany, the diagnostic outcomes of critically ill patients admitted to the resuscitation room in the ED of our academic 754-bed hospital should be analyzed., Methods: All resuscitation room patients between March 1st and April 15th 2020 were included in this retrospective study. Every patient with suspicion of SARS-CoV-2 infection received a pharyngeal swab for real-time polymerase chain reaction (rt-PCR), divided in the clinical subgroups of "highly suspicious for COVID-19" and "COVID-19 as differential diagnosis." All respiratory and infectious symptoms were included as at least "differential diagnosis" as an expanded suspicion strategy., Results: Ninety-five patients were included (trauma n = 14, critically ill n = 81). Of 3 highly suspicious patients, 2 had rt-PCR positive pharyngeal swabs. In 39 patients, COVID-19 was defined as differential diagnosis, and 3 were positive for SARS-CoV-2. Of them, pharyngeal swabs were positive in 1 case, while in 2 cases, only tracheal fluid was rt-PCR positive while the pharyngeal swabs were negative. In one of these 2 cases, chest computed tomography (CT) was also negative for ground-glass opacities but showed a pulmonary abscess and pulmonary embolism., Conclusion: We recommend an expanded suspicion strategy for COVID-19 due to unexpected diagnostic outcomes. Personal protective equipment should be used in every resuscitation room operation due to unexpected cases and initial knowledge gaps. Furthermore, tracheal fluid should be tested for SARS-CoV-2 in every intubated patient due to cases with negative pharyngeal swabs and negative chest CT., Competing Interests: There is no conflict of interest regarding this study reported by any of the authors., (Copyright © 2020 Sebastian Bergrath et al.)
