Abstract

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has impacted global health. Remdesivir was approved based on clinical trials demonstrating improved outcomes in hospitalized patients. The ReEs-COVID19 study provides real-world evidence on its effectiveness and safety across two periods: Pre-Omicron and Omicron. This retrospective, observational cohort study included 1610 patients hospitalized with COVID-19, treated with remdesivir during Pre-Omicron (September 2020–February 2021; n = 606) and Omicron (June 2022–March 2023; n = 1004) periods. Primary endpoint: time to discharge; Hepatic/renal function abnormalities were also investigated. In the Omicron period patients were older and had more comorbidities but remdesivir was initiated earlier (median: 2 days from symptom onset) compared to the Pre-Omicron period (8 days). ICU admissions rates and direct COVID-19-related deaths were significantly lower, but overall 30-day mortality was higher during the Omicron period. Earlier remdesivir administration was associated with faster discharge. Abnormal liver tests and acute kidney injury were rare across both periods. ReEs-COVID19 confirmed remdesivir’s effectiveness and safety in real-world clinical settings during both periods, underscoring its importance in treatment of hospitalized COVID-19 patients, especially when initiated earlier in the disease course. Further research is needed to evaluate its utility in specific subgroups (e.g., immuno-compromised) and in combination with other treatments.

#Neuroinvasive #Oropouche virus in a patient with #HIV from extra-Amazonian #Brazil

By G.M.
{Excerpt} A novel reassortant Oropouche virus (OROV) lineage (with medium [M], large [L], and small [S] RNA segments : M1L2S2) has driven Brazil's largest and most geographically widespread OROV epidemic , expanding beyond the endemic Amazon basin to establish local transmission across multiple Brazilian states and other previously unaffected Latin American countries . The rapid spread of this lineage underscores its evolutionary potential and reinforces its significance as a public health threat .1 Similar to chikungunya and Zika viruses, expanding arboviruses can exhibit unexpected clinical and epidemiological shifts , including vertical transmissions , neuroinvasive effects, and potentially fatal outcomes.2–4 Although OROV typically causes self-limited febrile illness, accumulating clinical and experimental evidence suggests neurotropic potential .5 This Correspondence describes the first confirmed case of neuroinvasive OROV infection caused by the emergent M1L2S2 lineage in ext...

No evidence of immune #exhaustion after repeated #SARS-CoV-2 #vaccination in vulnerable and healthy populations

By G.M.
Abstract Frequent SARS-CoV-2 vaccination in vulnerable populations has raised concerns that this may contribute to T cell exhaustion , which could negatively affect the quality of immune protection. Herein, we examined the impact of repeated SARS-CoV-2 vaccination on T cell phenotypic and functional exhaustion in frail older adults in long-term care (n = 23), individuals on immunosuppressive drugs (n = 10), and healthy adults (n = 43), in Canada . Spike-specific CD4+ and CD8+ T cell levels did not decline in any cohort following repeated SARS-CoV-2 vaccination, nor did the expression of exhaustion markers on spike-specific or total T cells increase. T cell production of multiple cytokines (i.e. polyfunctionality) in response to the spike protein of SARS-CoV-2 did not decline in any cohort following repeated vaccination. None of the cohorts displayed elevated levels of terminally differentiated T cells following multiple SARS-CoV-2 vaccinations. Thus, repeated SARS-CoV-2 vaccination was...

Chimeric #hemagglutinin and #M2 #mRNA #vaccine for broad #influenza subtype protection

By G.M.
Abstract Since multiple and unpredicted influenza viruses cause seasonal epidemics and even high-risk pandemics , developing a universal influenza vaccine is essential to provide broad protection against various influenza subtypes. Combined with the mRNA lipid nanoparticle-encapsulated (mRNA-LNP) vaccine platform and chimeric immunogen strategy , we developed a novel cocktail mRNA vaccine encoding chimeric HAs (cH5/1-BV, cH7/3) and intact M2 (termed Fluaxe), which confers broad protection against major circulating IAVs and IBVs , as well as highly pathogenic avian influenza . Two-dose intramuscular immunization of Fluaxe in mice elicited cross-reactive neutralizing antibodies , T cell responses, and long-lived immunity, resulting in robust protection against multiple lethal influenza virus infections and severe acute lung injuries . In particular, intramuscular administration stimulated systemic immunity together with a prominent lung tropism of memory cells . Moreover, Fluaxe immuniza...
