Solid Organ Transplant (SOT) recipients are at high risk of severe coronavirus disease-2019. Prior to the availability of vaccination, passive immunotherapies and effective antiviral therapeutics, the outcomes of COVID-19... read more
CAPSID Randomized Trial Results for High-dose Convalescent Plasma in COVID-19 Patients
COVID-19 convalescent plasma (CCP) has been considered a treatment option for COVID-19. This trial assessed the efficacy of a neutralizing antibody containing high-dose CCP in hospitalized adults with COVID-19 requiring respiratory... read more
COVID-19 Immune Evasion by the B.1.427/B.1.429 Variant of Concern
As battles to contain the COVID-19 pandemic continue, attention is focused on emerging variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus that have been deemed variants of concern because they... read more
Reduced Sensitivity of COVID-19 Variant Delta to Antibody Neutralization
The SARS-CoV-2 B.1.617 lineage was identified in October 2020 in India1–5. It has since then become dominant in some indian regions and UK and further spread to many countries6. The lineage includes three main subtypes... read more
REGN monoclonal antibodies work in selected hospitalised COVID-19 patients
New findings suggest a significant benefit from REGN in terms of the primary outcome of mortality for patients who have low levels of their own antibodies at the time of admission. This was an unexpected result for me... read more
COVID-19: Convalescent Plasma vs. Standard Plasma
Administration of convalescent plasma to hospitalized patients with coronavirus disease 2019 infection increased antibodies to severe acute respiratory syndrome coronavirus disease 2 but was not associated with improved outcome. Enrollment... read more
Temporal development and neutralising potential of antibodies against SARS-CoV-2 in hospitalised COVID-19 patients
Antibody responses are important in the control of viral respiratory infection in the human host. What is not clear for SARS-CoV-2 is how rapidly this response occurs, or when antibodies with protective capability evolve.... read more
FDA Limits Use of Convalescent Plasma as COVID-19 Treatment
The Food and Drug Administration (FDA) is scaling back its authorization of the use of convalescent blood-plasma for COVID-19 patients in an effort to guide physicians who have faced a confusing thicket of data about the... read more
COVID-19: Antibody-Dependent Enhancement
The simple definition of ADE is “raising antibodies that don’t protect, but actually make a viral infection even worse”. And obviously, that’s the opposite of what you want. Remember that there are “neutralizing”... read more
Management of Post-acute COVID-19 in Primary Care
Post-acute COVID-19 ("long covid") seems to be a multisystem disease, sometimes occurring after a relatively mild acute illness. Clinical management requires a whole-patient perspective. This article, intended for... read more
What is the Diagnostic Accuracy of Antibody Tests for the Detection of Infection with the COVID-19 Virus?
The sensitivity of antibody tests is too low in the first week since symptom onset to have a primary role for the diagnosis of COVID-19, but they may still have a role complementing other testing in individuals presenting... read more
Clinical Features of Patients Infected with Coronavirus in Wuhan, China
