A study reports the first case of an upper extremity deep vein thrombosis (DVT) recurrence due to COVID-19 infection

Researchers have reported the first case of COVID-19 triggering a rare occurrence of potentially severe blood clots forming in the arms.

Researchers identify anti-inflammatory prodrug Minnelide with potential against SARS-CoV-2

Using a transgenic mouse model of COVID-19, they have observed that treatment with Minnelide reduces viral load and inflammation in the lungs and improves survival. The study is currently available on the bioRxiv* preprint server.

Researchers identify mechanism of platelet hyperactivation in COVID-19 patients

A recent study conducted at the University of Pennsylvania and the Children’s Hospital of Philadelphia, USA, has revealed the mechanism of platelet hyperactivation in critically ill coronavirus disease 2019 (COVID-19) patients.

Study quantifies the true incidence of venous thromboembolism post esophagectomy

A new study presented today at the AATS 101st Annual Meeting, found that the percentage of patients undergoing esophagectomy for cancer who suffer Venous Thromboembolism (VTE) post-operatively is much higher than previously reported, with as many as 24 percent suffering from Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE).

Guidance on diagnosis and management of cerebral venous sinus thrombosis after a COVID-19 vaccine

Last Friday, the Centers for Disease Control and Prevention and the U.S. Food & Drug Administration lifted the pause in administration of the Johnson & Johnson (Janssen) COVID-19 vaccine in the U.S.

SARS-CoV-2 clade linked to disease severity in the early phase of the pandemic

A new study in the journal JAMA Network reports on the disease severity associated with some clades of the virus, from an analysis of genomes from specimens isolated in the initial phase of the pandemic.

Researchers aim to better understand clinical features associated with COVID-19 mortality

To better understand the COVID-19 clinical feaures associated with mortality, an interdisciplinary team of researchers has investigated important factors and their influence on a patient’s death.

Autoantibodies may contribute to severe COVID-19 and potential long-COVID-19 symptoms

New research in the USA and China. investigated how autoantibodies could mediate NETs during a COVID-19 infection. Extensive damage to the body from neutrophil extracellular traps (NETs) after infection may be contributing to thromboinflammation and the symptoms experienced by COVID-19 ‘long-haulers’.

The interaction between blood clotting and SARS-CoV-2 infection

Coagulopathy - a condition in which the blood's ability to clot is impaired, is recognized as a significant aspect of morbidity in COVID-19 patients. In a recent study, Prof Lewis Cantley and a team of researchers explored the role of coagulation factors in the SARS-CoV-2 infection. Their recent study is posted on the bioRxiv server.

COVID-19 is more difficult to diagnose in children and adolescents, finds study

The ongoing pandemic of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread to over 192 countries and territories, causing an enormous loss of lives and economic devastation.

SARS-CoV-2 spike S1 subunit induces hypercoagulability

The vascular complications of the condition include a range of various coagulopathies that cause bleeding and thrombocytopenia or a hypercoagulable state. A new preprint research paper posted to the medRxiv server describes the role of a fibrinogen-related protein in inducing these clinical features of COVID-19.

Researchers examine long-term immune responses following COVID-19 across clinically diverse cohort

A new study by researchers at the University of California, San Francisco, discusses the different aspects of long-term immune responses in a wide sample of patients, as well as how they vary in clinical severity and sequelae.

Children with MIS-C have highly activated immune systems, study finds

Taking the first deep dive into how the immune system is behaving in patients with multisystem inflammatory syndrome in children (MIS-C), researchers at Children's Hospital of Philadelphia and the Perelman School of Medicine at the University of Pennsylvania have found that children with this condition have highly activated immune systems that, in many ways, are more similar to those of adults with severe COVID-19.

Biomarkers in the blood can predict severe outcomes in COVID-19 patients

When patients with COVID-19 arrive in emergency rooms, there are relatively few ways for doctors to predict which ones are more likely to become critically ill and require intensive care and which ones are more likely to enjoy a quick recovery.

Could Galectin-3 be a potential biomarker to help identify severe COVID-19 early?

Researchers have measured the galectin-3 levels in the sera of hospitalized patients. They found initial high levels indicate patients will become severely ill, suggesting it could be used as a predictor of severe disease.

Hematological findings in Amazonian patients with COVID-19

To discriminate between patients with severe and non-severe COVID-19 quickly, researchers from Peru looked for prognostic signatures in the blood samples of COVID-19 patients. Virgilio E. Failoc-Rojas et al. examined laboratory results and clinical prognosis of COVID-19 patients from a hospital in the Peruvian Amazon.

Early use of therapeutic anticoagulation does not improve survival of critically ill COVID-19 patients

Although abnormal blood clotting has been identified as one of the primary causes of death from COVID-19, early treatment in an intensive care unit (ICU) with therapeutic anticoagulation (anti-clotting) for adults who are critically ill with COVID-19 does not appear to improve chances of survival, and could do more harm than good by increasing the risk for major bleeding, a multicenter research group cautions.

Hyperinflammatory conditions drive gender differences in COVID-19 severity and mortality

Recently researchers from India analyzed gender differences in COVID-19-related hyperinflammatory conditions resulting in mortality in Indian patients. The study is published on the preprint server, medRxiv*.

Circulating antiphospholipid antibodies drive endothelial cell activation in COVID-19

With the emergence of COVID-19 (coronavirus disease 2019), researchers have been closely investigating the complex interplay between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the human immune system, and COVID-19 disease severity.
