  Despite numerous studies on SARS-CoV-2-induced inflammation, we still lack markers for rapid disease progression with admission to intensive care unit (ICU) or respiratory failure(RF). Few studies have evaluated the prognostic value of routine diagnostic repertoire available at most hospitals. The NOR-Solidarity trial is an independent add-on study to the WHO Solidarity trial, evaluating hydroxychloroquine (HCQ)and remdesivir compared to standard of care in hospitalized COVID-19 patients [1]. We explored whether standard biomarkers in peripheral blood could give information on ICU admission and RFin hospitalized COVID-19 patients.

  The genetic make-up of an individual contributes to the susceptibility and response to viral infection. Although environmental, clinical and social factors have a role in the chance of exposure to SARS-CoV-2 and the severity of COVID-191,2, host genetics may also be important. Identifying host-specific genetic factors may reveal biological mechanisms of therapeutic relevance and clarify causal relationships of modifiable environmental risk factors for SARS-CoV-2 infection and outcomes. We formed a global network of researchers to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity. Here we describe the results of three genome-wide association meta-analyses that consist of up to 49,562 patients with COVID-19 from 46 studies across 19 countries. We report 13 genome-wide significant loci that are associated with SARS-CoV-2 infection or severe manifestations of COVID-19. Several of these loci correspond to previously documented associations to lung or autoimmune and inflammatory diseases3,4,5,6,7. They also represent potentially actionable mechanisms in response to infection. Mendelian randomization analyses support a causal role for smoking and body-mass index for severe COVID-19 although not for type II diabetes. The identification of novel host genetic factors associated with COVID-19 was made possible by the community of human genetics researchers coming together to prioritize the sharing of data, results, resources and analytical frameworks. This working model of international collaboration underscores what is possible for future genetic discoveries in emerging pandemics, or indeed for any complex human disease.

  Background: New treatment modalities are urgently needed for patients with COVID-19. The World Health Organization (WHO) Solidarity trial showed no effect of remdesivir or hydroxychloroquine (HCQ) on mortality, but the antiviral effects of these drugs are not known. Objective: To evaluate the effects of remdesivir and HCQ on all-cause, in-hospital mortality; the degree of respiratory failure and inflammation; and viral clearance in the oropharynx. Design: NOR-Solidarity is an independent, add-on, randomized controlled trial to the WHO Solidarity trial that included biobanking and 3 months of clinical follow-up (ClinicalTrials.gov: NCT04321616). Setting: 23 hospitals in Norway. Patients: Eligible patients were adults hospitalized with confirmed SARS-CoV-2 infection. Intervention: Between 28 March and 4 October 2020, a total of 185 patients were randomly assigned and 181 were included in the full analysis set. Patients received remdesivir (n = 42), HCQ (n = 52), or standard of care (SoC) (n = 87). Measurements: In addition to the primary end point of WHO Solidarity, study-specific outcomes were viral clearance in oropharyngeal specimens, the degree of respiratory failure, and inflammatory variables. Results: No significant differences were seen between treatment groups in mortality during hospitalization. There was a marked decrease in SARS-CoV-2 load in the oropharynx during the first week overall, with similar decreases and 10-day viral loads among the remdesivir, HCQ, and SoC groups. Remdesivir and HCQ did not affect the degree of respiratory failure or inflammatory variables in plasma or serum. The lack of antiviral effect was not associated with symptom duration, level of viral load, degree of inflammation, or presence of antibodies against SARS-CoV-2 at hospital admittance. Limitation: The trial had no placebo group. Conclusion: Neither remdesivir nor HCQ affected viral clearance in hospitalized patients with COVID-19.

  BAKGRUNN Akuttmottaket ved Oslo universitetssykehus, Ullevål, innførte i 2017 en egen prosedyre for mottak av pasienter med mistenkt sepsis. Et strukturert sepsismottak skulle utløses hos disse pasientene, spesielt hvis minst to av tre kriterier i skåringsverktøyet Quick Sequential Organ Failure Assessment (qSOFA) var oppfylt. Vi ønsket å undersøke om tiltaket var hensiktsmessig for å oppfylle nasjonale anbefalinger om oppstart av antibiotika innen én time ved behandling av sepsis. MATERIALE OG METODE Voksne pasienter med mistenkt sepsis som ble tatt imot i strukturerte teammottak i perioden 15.5.–15.11.2017 ble inkludert. Det ble gjort en retrospektiv vurdering av om de inkluderte faktisk hadde hatt sepsis eller ikke. RESULTATER Det ble gitt antibiotika mot mistenkt sepsis i 216 strukturerte pasientmottak (172 sepsismottak og 44 medisinske teammottak). 175 (81 %) av pasientene fikk antibiotika innen den første timen i akuttmottaket. Mediantid fra ankomst til antibiotika ble igangsatt var 35 minutter. Bruk av qSOFA-skår alene fanget opp 80 (71 %) av de 112 pasientene som i ettertid ble klassifisert til å ha sepsis. FORTOLKNING Etter innføring av strukturert mottak av pasienter med mistenkt sepsis ble antibiotikabehandling i stor grad gitt innen én time.
