Article Synopsis
  • The study investigates how antiviral monoclonal antibodies (mAbs), particularly casirivimab and imdevimab (CAS+IMD), affect immune responses when individuals are vaccinated against SARS-CoV-2 after receiving mAb treatment.
  • It was found that the presence of CAS+IMD during vaccination reduced the effectiveness of the vaccine in generating neutralizing antibodies, though other immune responses remained intact.
  • This reduction in antibody production is linked to "epitope masking," but can be reversed with booster shots, and influences the immune response differently in those who had not yet begun their natural immunity when treated with mAbs.

Article Synopsis
  • Fibrodysplasia ossificans progressiva (FOP) is a rare condition where bones form in soft tissue, referred to as heterotopic ossification (HO), and this study examined imaging methods to identify and measure new HO lesions.
  • The research analyzed data from a phase 2 clinical trial comparing the effectiveness of garetosmab (a therapy) with a placebo in adults with FOP, utilizing both PET/CT and CT scans to detect lesions over 28 weeks.
  • Results showed that both PET/CT and CT-only methods detected a similar number and volume of new lesions, indicating that CT-only imaging is an effective alternative for monitoring HO changes in FOP patients.

Article Synopsis
  • Passive administration of the monoclonal antibody cocktail CAS + IMD showed positive clinical outcomes in hospitalized COVID-19 patients, particularly those who were seronegative at the start of treatment.
  • The study involved 46 patients and used advanced immunoprofiling techniques to assess how the antibody treatment influenced immune responses over time, from October 2020 to April 2021.
  • Results indicated that CAS + IMD not only reduced acute inflammation but also enhanced recovery without harming the host's T cell immune response, suggesting a beneficial anti-inflammatory effect that needs further exploration.

Heart failure is a leading cause of morbidity and mortality. Elevated intracardiac pressures and myocyte stretch in heart failure trigger the release of counter-regulatory natriuretic peptides, which act through their receptor (NPR1) to affect vasodilation, diuresis and natriuresis, lowering venous pressures and relieving venous congestion. Recombinant natriuretic peptide infusions were developed to treat heart failure but have been limited by a short duration of effect.

Background: Deeper insight is needed on how monoclonal antibodies (mAbs) affect vaccine-mediated immune responses when targeting the same protein. We describe the first prospective randomised trial designed to understand mAb-mediated alterations in vaccine-induced immune responses to SARS-CoV-2 spike protein epitopes.

Methods: This randomised, open-label, parallel-group study assessed the potential interaction of a mAb combination, casirivimab and imdevimab, with a vaccine, Moderna's mRNA-1273, in healthy SARS-CoV-2 immunologically naive, seronegative adults at six centres in the USA.
