Indirect viral infection of the kidneys by SARS-CoV-2-induced inflammatory reaction

SARS-CoV-2-associated acute kidney injury is not uncommon. Many hospitalized COVID-19 patients - as many as 80% of critically ill COVID-19 patients, according to a current study - develop acute kidney injury, but without requiring dialysis in most cases. Proteinuria and hematuria are present in about half the cases.

Monocytes could be critical in dysregulated immunity in COVID-19

A new study by Spanish researchers as part of the GEN-COVID Project, and published on the preprint server medRxiv* in June 2020, suggests that monocytes are primarily involved in triggering the hyperinflammatory immune response that may underlie severe COVID-19 infection.

SARS-CoV-2 invasion of central nervous system through olfactory tract

As the COVID-19 pandemic continues to claim lives throughout the world, the evidence is mounting that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects the respiratory tract as well as the central nervous system. Now, a new study by German researchers published on the preprint server bioRxiv in June 2020 describes various neurological manifestations of COVID-19, as well as the underlying pathophysiology.

Tocilizumab in COVID-19 patients on mechanical ventilation

Now, a new study by researchers from the University of Michigan and published on the online preprint server medRxiv* in June 2020 shows that the cytokine inhibitor tocilizumab could have a favorable effect on survival in the most severely infected patients who require mechanical ventilation. This needs to be confirmed by clinical trials.

Approved drug could help dampen massive immune response associated with severe COVID-19

The drug acalabrutinib, FDA-approved for the treatment of several types of B cell cancers, improved the oxygenation levels and decreased molecular markers of inflammation in a majority of 19 patients hospitalized for the treatment of severe COVID-19, according to a new study by Mark Roschewski and colleagues.

Designing a prototype spike protein vaccine for SARS-CoV-2

A recent study published on the preprint server bioRxiv in June 2020 reports the development of a prototype vaccine containing multiple antigenic sites, based on the spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is causing the current COVID-19 pandemic. If successful, this could lead to the development of an effective, non-allergenic vaccine that induces both humoral and cellular immunity.

New research focuses on protein-coding gene's role in inflammatory bowel disease

A protein-coding gene associated with autoimmune diseases such as Crohn's disease and ulcerative colitis, collectively referred to as inflammatory bowel disease, or IBD, will be the focus of new research in the School of Medicine at the University of California, Riverside.

Hesperos’ immune system-on-a-chip emulates immune reactions for tissue damage and acute inflammation

Hesperos Inc., pioneers of the Human-on-a-Chip in vitro system, today announced the publication of a new peer-reviewed publication that describes how the company’s technology can be used to investigate immune responses following treatment with biological therapeutics for multi-organ systemic diseases, including cancer, infectious diseases and inflammatory disorders.

Does interferon therapy work in COVID-19?

A new study published on the preprint site medRxiv in May 2020 reports on the efficacy of interferons in treating COVID-19. The research could help evaluate the place of such therapy in the management of this disease.

Children with COVID-19 presenting with sudden severe lung disease

Even as the COVID-19 pandemic continues to seek out new victims, puzzling new presentations are further confusing the situation. A new study published online in The Lancet Rheumatology in May 2020 reports a case of severe COVID-19 in a child who rapidly developed acute respiratory distress symptoms without prior respiratory symptoms. This case should alert clinicians to consider this diagnosis in children as well.

Teens develop septic shock due to COVID-19

Since the emergence of the novel coronavirus disease (COVID-19), most people who develop severe illness are older adults, those with underlying medical conditions, and those who are immunocompromised. Though children are mostly spared, some adolescents developed septic shock due to COVID-19, a new study has found.
