Hospitalized COVID-19 patients more likely to experience heavy bleeding when prescribed full-dose blood thinners

Patients with COVID-19 in the intensive care unit (ICU) prescribed full-dose blood thinners are significantly more likely to experience heavy bleeding than patients prescribed a smaller yet equally effective dose, according to a recent University at Buffalo-led study.

Early-stage alveolar epithelial cell necrosis linked to COVID-19-induced acute respiratory distress syndrome

A new study analyzed whether alveolar epithelial cell necrosis at an early stage SARS-CoV-2 infection and subsequent releases of damage-associated molecular patterns could aggravate COVID-19-associated acute respiratory distress syndrome.

LIVE-AIR trial demonstrates efficacy of Lenzilumab for treatment of COVID patients with decreased oxygen saturation

The LIVE-AIR phase 3 clinical trial is associated with early treatment of hyperinflammatory response with the humanized monoclonal antibody lenzilumab in COVID-19 patients with decreased oxygen saturation. The study results are posted to the medRxiv* preprint server.

Thrombosis may increase mortality risk in hospitalized COVID-19 patients

A team of US-based scientists has recently explored various risk factors associated with the poor prognosis of coronavirus disease 2019 (COVID-19). They have identified thrombosis-related risk factors as a major predictor of in-hospital COVID-19 related mortality. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Study analyzes association between obesity and endothelial dysfunction in COVID-19 patients

In COVID-19 patients, obesity is the factor most associated with the development of endothelial dysfunction, a condition in which the blood vessels become unable to contract and relax adequately, increasing the risk of events such as heart attacks, thrombosis (blood clotting), and stroke.

Changes in fibrin clot structure contributes to thrombosis risk in severe COVID-19

Researchers from Europe recently demonstrated altered levels of factor XII (FXII) and its activation products in 2 independent cohorts of critically ill patients with COVID-19 compared to patients suffering from severe acute respiratory distress syndrome caused by the influenza virus (acute respiratory distress syndrome (ARDS)-influenza).

First dose of COVID-19 mRNA vaccine (BNT162b2) reduced platelet polyP levels in young females

In a recent study, scientists have tested the hypothesis that indicates the role of polyP in the COVID-19 mRNA vaccine-induced immune responses.

SARS-CoV-2 can cause sustained biochemical dysregulation that results in long-COVID

This state has come to be known as long-COVID, and in a paper recently uploaded to the preprint server medRxiv* by Simjanoska et al. (September 7th, 2021) the biochemical parameters of long-COVID patients with prior mild, moderate, or severe COVID-19 that resulted in hospitalization are tracked in detail, finding a characteristically dysregulated immune and inflammatory response in the most seriously ill.

Metabolic and immune markers as tools for risk stratification and monitoring in COVID-19

In a new study posted to the medRxiv* server scientists from Weil Cornell University and Stony Brook University in New York attempted to identify the metabolic and immune markers associated with severe COVID-19 disease using high-throughput targeted nuclear magnetic resonance (NMR) spectroscopy and high-dimensional flow cytometry. This will facilitate risk stratification, monitoring, and therapeutic interventions in COVID-19 patients.
