The constant domains of antibodies are important for effector functions, but less is known about how they can affect binding and neutralization of viruses. Here, we evaluated a panel of human influenza virus monoclonal antibodies (mAbs) expressed as IgG1, IgG2, or IgG3. We found that many influenza virus-specific mAbs have altered binding and neutralization capacity depending on the IgG subclass encoded and that these differences result from unique bivalency capacities of the subclasses. Importantly, subclass differences in antibody binding and neutralization were greatest when the affinity for the target antigen was reduced through antigenic mismatch. We found that antibodies expressed …

Study objective: This study sought to assess the predictive value of H2FPEF score in patients with COVID-19.

Design: Retrospective study.

Setting: Rush University Medical Center.

Participants: A total of 1682 patients had an echocardiogram in the year preceding their COVID-19 admission with a preserved ejection fraction (≥50%). A total of 156 patients met inclusion criteria. Interventions: Patients were divided into H2FPEF into low (0–2), intermediate (3–5), and high (6–9) score H2FPEF groups and outcomes were compared.

Main outcome measures: Adjusted multivariable logistic regression models evaluated the association between H2FPEF score group and a composite outcome for severe COVID-19 infection consisting …
