Multicenter Study Observational Study
Few bacterial co-infections but frequent empiric antibiotic use in the early phase of hospitalized patients with COVID-19: results from a multicentre retrospective cohort study in The Netherlands.
Knowledge on bacterial co-infections in COVID-19 is crucial to use antibiotics appropriately. Therefore, we aimed to determine the incidence of bacterial co-infections, antibiotic use and application of antimicrobial stewardship principles in hospitalized patients with COVID-19. ⋯ On presentation to the hospital bacterial co-infections are rare, while empiric antibiotic use is abundant. This implies that in patients with COVID-19 empiric antibiotic should be withheld. This has the potential to dramatically reduce the current overuse of antibiotics in the COVID-19 pandemic.

There are scarce data on soluble Fas Ligand (sFasL), one of the main ligands that activate the apoptosis extrinsic pathway, in septic patients. In a small study of septic children were found higher plasma sFasL levels in non-survivors compared with survivors; however, an association between blood sFasL levels and mortality controlling for sepsis severity was not stablished due to the small sample size of the study. Therefore, the main objective of this study was to determine whether there is an association between blood sFasL concentrations and mortality in septic patients controlling for sepsis severity. Methods: Septic patients were included in this observational and prospective study conducted in three Spanish Intensive Care Units. Serum samples at diagnosis of sepsis were obtained for serum sFasL levels determination. ⋯ The main new finding from our study was that serum sFasL concentrations were associated with mortality in septic patients controlling for sepsis severity. Highlights Blood sFasL concentrations were higher in non-survivor than in survivor patients. There is an association between blood sFasL concentrations and mortality in septic patients. Blood sFasL concentrations could predict mortality of septic patients.

The clinical course and viral detection period in mild or asymptomatic coronavirus disease 2019 (COVID-19) patients are not yet known. The presumed low diagnostic sensitivity of upper respiratory specimens for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) makes it difficult to confirm infection and recommend de-isolation. ⋯ The detection of SARS-CoV-2 lasting more than 3 weeks was common in mild or asymptomatic patients. Upper respiratory RT-PCR results were frequently reversed from negative to positive.
