The connection between severe COVID-19 and white blood cell counts

However, in other research, white blood cells' exact roles and subtypes in severe COVID-19 are still unclear. The team writes, "It is unknown if blood cell counts before infection are associated with the risk of developing severe COVID-19." They explained that the numbers of these cell types could be influenced by several factors such as age, gender, disease status, and medications.

Characterization of prognostic markers to predict COVID-19 severity

A team of scientists from the United Kingdom has revealed that markers of endothelial cell injury are associated with severe and fatal outcome of coronavirus disease 2019 (COVID-19). The study is currently available on the medRxiv* preprint server.

Cancer-killing T cells release chemicals to direct swarms towards tumors

When immune system T cells find and recognise a target, they release chemicals to attract more T cells which then swarm to help subdue the threat, shows a new study published today in eLife.

Are antibiotics being over prescribed in COVID-19?

A new study published on the preprint server medRxiv in October 2020 shows that the baseline levels of inflammatory markers and C-reactive protein (CRP) in relation to antibiotic administration can rule out bacterial co-infections and help reduce the unnecessary use of antibiotics.

Researchers explore molecular factors that drive the severity of COVID-19

While most COVID-19 cases are asymptomatic or mild, severe complications associated with acute respiratory distress have led to more than one million deaths worldwide in just several months.

Pathways contributing to hypercoagulability in severe SARS‐CoV‐2 patients

In a study by researchers explored the possible mechanisms of the clotting disorder, focusing on the role of hypoxia-related activation of coagulation factors; cytokine storm, activation of neutrophils, and the release of neutrophil extracellular traps.

Study shows unique cardioprotective properties of an old drug

A drug costing less than 2 euros per dose could reduce the long term consequences of a heart attack, benefitting millions of patients. Metoprolol, a member of the beta-blocker class of drugs that has been in use for more than 40 years, has been found to have unique cardioprotective properties.

Cats and dogs are low risk for SARS-CoV-2 transmission to humans

Researchers from the College of Veterinary Medicine and Biomedical Sciences, Colorado State University studied the possible transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among domestic cats and dogs.

Study reveals how immune cells sacrifice themselves to help fight off infections

Whether flu or coronavirus, it can take several days for the body to ramp up an effective response to a viral infection.

Lung tissue in fatal COVID-19 shows broad cell tropism and extensive damage

In a recent preprint paper published on the medRxiv server, researchers demonstrated their investigation of fatal COVID-19 patients to assess infection in various cell types and the extent of damage it caused to the lung tissues.

Maternal immune cells could bring SARS-CoV-2 to the placenta

Researchers from Canada and Brazil collaborated to explore the possibility of perinatal transmission of the virus from pregnant mothers to their babies and the risk of preterm birth.

A study contradicting the phenotypical relationship between plasmablasts and developing neutrophils

A team of scientists from Australia challenges the findings of a recent study by Wilk et al. demonstrating that plasmablasts transdifferentiate into developing neutrophils in severe coronavirus disease 2019 (COVID-19). The Australian study is currently available on the bioRxiv preprint server.

Hamsters and ferrets clear low dose SARS-CoV-2 infection in 14 days

A recent study by French researchers has demonstrated that experimental exposure to severe acute respiratory coronavirus 2 (SARS-CoV-2) is capable of inducing mild infection in hamsters and ferrets within 7 – 10 days of exposure. However, the infection completely resolves within 14 days. The study is currently available on the bioRxiv preprint server.

Anti-N-protein IgG may predict severity of COVID-19

A recent study by researchers at the University of Miami, Miami VA Healthcare System and Express Gene and published on the preprint server medRxiv in September 2020 reports on the prognostic significance of the anti-N Immunoglobulin G (IgG) antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Risk factors for mortality among hospitalized patients with COVID-19

A new study by scientists at biotechnology company Genentech, Inc., and published on the preprint server medRxiv in September 2020 attempts to identify the factors which may shape the risk for death in COVID-19 disease.

27 Sep 2020

AI used to define the cytokine storm implicated in fatal COVID-19

A new study published on the preprint server bioRxiv* in September 2020 reports the use of artificial intelligence (AI) to identify an invariant or universal host immune response found in all viral pandemics so far. The association of this response with severe COVID-19 phenotypes indicates a new understanding of the human immune response in viral pandemics.

Research says in SARS-CoV-2 canine infection, transmission unlikely

A new study published on the preprint server bioRxiv* in September 2020 shows that pet dogs have been falling sick and dying of a mysterious respiratory infection, often showing the presence of anti- severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies, even though in many cases they do not test positive for COVID-19.

Stroke patients with COVID-19 have increased systemic inflammation, higher mortality risk

Stroke patients who also have COVID-19 showed increased systemic inflammation, a more serious stroke severity and a much higher rate of death, compared to stroke patients who did not have COVID-19, according to University of Alabama at Birmingham research led by Chen Lin, M.D., an assistant professor in the UAB Department of Neurology.

Animal data supports efficacy of baricitinib vs SARS-COV-2

The high burden of disease caused by the COVID-19 pandemic has led to much research on effective ways to mitigate the health, social, and economic impact of the spread of the infection. A recent study published on the preprint server bioRxiv* in September 2020 reports on the characteristics of the drug baricitinib when used as monotherapy to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
