In a survey of household cats and dogs of laboratory-confirmed COVID-19 patients, we found a high seroprevalence of SARS-CoV-2 antibodies, ranging from 21% to 53%, depending on the positivity criteria chosen. Seropositivity was significantly greater among pets from COVID-19+ households compared to those with owners of unknown status. Our results highlight the potential role of pets in the spread of the epidemic.

Thymomas have been associated with the generation of paraneoplastic autoantibodies to neurogenic epitopes, collapsin-response-mediator protein-5 receptor (CRMP-5) and alpha-amino-3-hydroxyl-5methyl-4isoxazolepropionic acid receptor (AMPAR), in patients with acute viral infection. We report a patient with thymoma and myasthenia gravis, with SARS-CoV-2 infection, who became comatose secondary to autoimmune encephalitis. Plasmapheresis, high-dose steroids, pyridostigmine, eculizumab, and rituximab did not restore neurologic function.

BackgroundThe first Corona Monitoring Nationwide (RKI-SOEP) study (October 2020-February 2021) found a low pre-vaccine SARS-CoV-2 antibody seroprevalence (2.1%) in the German adult population (≥ 18 years).AimThe objective of this second RKI-SOEP (RKI-SOEP-2) study in November 2021-March 2022 was to estimate the prevalence of SARS-CoV-2-specific anti-spike and/or anti-nucleocapsid (anti-N) IgG antibodies (combined seroprevalence), past infection based on infection-induced seroprevalence (anti-N), and basic immunisation (at least two antigen contacts through vaccination or infection) in individuals aged ≥ 14 years.

The emergence of mRNA vaccines offers great promise and a potent platform in combating various diseases, notably COVID-19. Nevertheless, challenges such as inherent instability and potential side effects of current delivery systems underscore the critical need for the advancement of stable, safe, and efficacious mRNA vaccines. In this study, a robust mRNA vaccine (cmRNA-1130) eliciting potent immune activation has been developed from a biodegradable lipid with eight ester bonds in the branched tail (AX4) and synthetic circular mRNA (cmRNA) encoding the trimeric Delta receptor binding domain of the SARS-CoV-2 spike protein.

Objective: The occurrence of hypofibrinogenemia after tocilizumab treatment has attracted increasing attention, which may cause bleeding and even life-threatening. This study aims to explore the risk factors for tocilizumab-induced hypofibrinogenemia (T-HFIB) and construct a risk prediction model.
Methods: A total of 221 inpatients that received tocilizumab from 2015 to 2023 were retrospectively collected and divided into T-HFIB group or control group.

The ongoing emergence of SARS-CoV-2 variants, combined with antigen exposures from different waves and vaccinations, poses challenges in updating COVID-19 vaccine antigens. We collected 206 sera from individuals with vaccination-only, hybrid immunity, and single or repeated omicron post-vaccination infections (PVIs), including non-JN.1 and JN.
