Background A new or re-emerging infectious disease pandemic ranks among the highest priorities for civic contingency planning. Despite advances in preclinical and clinical research methods, patient-centered clinical research is not effectively embedded in outbreak responses to inform clinical management of patients and public health responses. Pref...

Objectives: The presence of respiratory viruses and the association with outcomes were assessed in invasively ventilated ICU patients, stratified by admission diagnosis. Design: Prospective observational study. Setting: Five ICUs in the Netherlands. Patients: Between September 1, 2013, and April 30, 2014, 1,407 acutely admitted and invasivel...

Background: Clinical guidelines suggest testing for respiratory viruses during the influenza season, but are unclear which categories of patients on the intensive care unit (ICU) should be tested. Objective: We described the clinical practice of diagnostic testing for respiratory virus infections in patients presenting to ICU with suspected comm...

Background: Secondary bacterial pneumonia is a frequent complication of influenza, associated with high morbidity and mortality. We hypothesized that treatment with neutralizing influenza A antibody AT10_002 protects against severe secondary pneumococcal infection in a mouse model of influenza A infection. Methods: Influenza A (H3N2) virus‐infected...

Purpose of review: The pathogenesis and impact of coinfection, in particular bacterial coinfection, in influenza are incompletely understood. This review summarizes results from studies on bacterial coinfection in the recent pandemic influenza outbreak. Recent findings: Systemic immune mechanisms play a key role in the development of coinfection...

Acute respiratory distress syndrome (ARDS) is a condition affecting 10% of patients requiring admission to the intensive care unit and results from endothelial dysfunction, alveolar epithelial injury and unbalanced inflammation, leading to exudative pulmonary oedema. A significant portion of these patients experience a lung injury that fails to res...

Human herpesviruses, particularly cytomegalovirus (CMV) and herpes simplex virus (HSV), frequently reactivate in critically ill patients, including those with acute respiratory distress syndrome (ARDS) related to coronavirus disease 2019 (COVID-19). The clinical interpretation of pulmonary herpesvirus reactivation is challenging and there is ongoin...

By September 2022, more than 600 million cases of SARS-CoV-2 infection have been reported globally, resulting in over 6.5 million deaths. COVID-19 mortality risk estimators are often, however, developed with small unrepresentative samples and with methodological limitations. It is highly important to develop predictive tools for pulmonary embolism...

Importance Research diversity and representativeness are paramount in building trust, generating valid biomedical knowledge, and possibly in implementing clinical guidelines. Objectives To compare variations over time and across World Health Organization (WHO) geographic regions of corticosteroid use for treatment of severe COVID-19; secondary obj...

Background COVID-19 has been associated with a broad range of thromboembolic, ischemic, and hemorrhagic complications (coagulopathy complications). Most studies have focused on patients with severe disease from high-income countries (HIC). Objectives The main aims were to compare the frequency of coagulopathy complications in developing countries (...

There is increasing attention for opportunistic pathogens such as Aspergillus fumigatus complicating SARS-CoV-2 infections in the critically ill. For invasive fungal disease, establishing a clear diagnosis can be challenging due to the invasiveness of diagnostic procedures required for a proven case. Here we present one of the first proven cases of...

In routine surveillance and diagnostic testing, influenza virus samples are typically collected only from the upper respiratory tract (URT) due to the invasiveness of sample collection from the lower airways. Very little is known about virus variation in the lower respiratory tract (LRT) and it remains unclear if the virus populations at different...

Respiratory viruses are frequently detected in adult patients admitted to the intensive care unit (ICU) and are increasingly being recognised for their role as causal agents in severe respiratory tract infections. Diagnostic sensitivity and time to result have greatly improved with the advent of molecular diagnostics. However, the burden of viral r...

The prevalence of viral respiratory tract infections in critically ill patients is uncertain, as well as the optimal diagnostic method to detect these. The aim of this study was to assess the prevalence of viral respiratory tract infections in mechanically ventilated patients, in both the upper and lower respiratory tract.

Secondary bacterial pneumonia after influenza infection can cause severe disease with a high mortality. Recently, a new group 2 influenza A antibody (AT10_002) has been developed, which binds to multiple H3 and H7 subtypes. In a mouse model of primary influenza infection, treatment with AT10_002 as a fusion antibody protects against lethal infectio...

Background: There is uncertainty about the prevalence of viral respiratory tract infections in intensive care unit (ICU) patients, and whether these infections contribute to disease severity and final outcome. Furthermore, the pattern of viral shedding during influenza infections in critically ill patients is largely unknown. Objectives: This study...
