Instability in gut microbiota associated with COVID-19-related complications and mortality, study finds

Researchers from Germany recently analyzed saliva and fecal samples from SARS-CoV-2 infected and post-COVID-19 patients and controls while considering multiple influencing factors during hospitalization. This study is available on the bioRxiv* preprint server.

Anti-rheumatic drug as a potential candidate for treating COVID-19

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produces inflammatory cytokine storms. But an FDA-approved anti-rheumatic drug, Auranofin, used to treat autoimmune and infectious diseases, may also help serve as an antiviral treatment for COVID-19 infection.

New study finds SARS-CoV-2 causes retinal infection

Can coronavirus disease 2019 (COVID-19) affect the eye? New research suggests the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can enter the eye and infect photoreceptor and retinal ganglion cells. In addition, SARS-CoV-2 infection increases the expression of several inflammatory genes, including the cytokine interleukin 33 (IL33), which is linked to COVID-19 disease and retinal degeneration.

Comparing lateral flow testing with RT-PCR to detect SARS-CoV-2

Lateral flow devices (LFDs) are point-of-care tests that require significantly more time to develop than RT-PCR assays but can be used locally with minimal to no training, some of which can provide results in as little as 30 minutes. However, there have been some worries about the sensitivity of such kits. As a result, researchers from Micropathology Ltd have been comparing the two methods.

How long does natural immunity produced by SARS-CoV-2 infection last?

A new study posted to the bioRxiv* preprint server followed the adaptive immune response in convalescent patients from Swedish and Italian cohorts—which had earlier shown long-lasting adaptive immune responses to the G614 strain—for 15 months. Here, specific antibody levels and neutralizing antibody titers were tested against variants of concern (VOCs).
