New insights can pave the way for targeted therapies to fight blood clots in COVID-19 patients

Driven by the mystery of the blood clots reported in both living and deceased COVID-19 patients, researchers from Shoolini University, India, dig deeper into the pathogenesis of COVID-19 and other similar viral diseases, looking for ways in which these clots could be formed.

Researchers reanalyze COVID RECOVERY trial data on tocilizumab

A Bayesian analysis of the RECOVERY trial suggests the immunosuppressive drug tocilizumab can reduce deaths in hospitalized COVID-19 patients taking corticosteroids as well as patients on oxygen or non-invasive ventilation and likely increases hospital discharge rates. However, it is not clear if patients on invasive ventilation also benefit.

Green tea catechins might be useful as pan-coronavirus inhibitors

Scientists from the Queen’s University, Canada, have recently uncovered the broad-spectrum antiviral activity of epigallocatechin gallate, a bioactive compound from green tea, against highly pathogenic coronaviruses found in humans and animals. The compound prevents viral infection by interfering with virus-host cell attachment. The study is currently available on the bioRxiv* preprint server.

Bivalent DNA SARS-CoV-2 vaccine induces strong humoral and cellular immunity in mice

A team of UK-based scientists has developed and validated a DNA vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that encodes both spike receptor-binding domain (RBD) and nucleocapsid of the virus as vaccine immunogens.

Resurgent SARS-CoV-2 infections in England linked to Delta variant

A major factor contributing to the ongoing pandemic of severe acute respiratory coronavirus 2 (SARS-CoV-2) has been the emergence of new variants. Because the mutations of the original virus make variants more transmissible, there is more potential for the contagion to spread through social mixing due to the easing of lockdown.

COVID-19 prevalence in the U.S. has far exceeded the known number of cases

In a new study, National Institutes of Health researchers report that the prevalence of COVID-19 in the United States during spring and summer of 2020 far exceeded the known number of cases and that infection affected the country unevenly.

New class of compounds can stop the reproduction of coronavirus

A human genetic mechanism hijacked by SARS-CoV-2, the coronavirus behind the COVID-19 pandemic, to help it spread also makes it vulnerable to a new class of drug candidates, a new study finds.

A study of circulating biomarkers in hospitalized patients infected with SARS-CoV-2 alpha variant

Now, a new study published on the medRxiv* preprint server proposes a rapid method to identify the mutations in B.1.1.7 (N501Y mutation and H69/V70 deletion) and the impact of this variant on various biomarkers in hospitalized patients. This is the first study that correlates the biomarker levels to SARS-CoV-2 variants.

SARS-CoV-2 detection with a simple, inexpensive, and sensitive molecular test

Researchers from the US recently described a rapid molecular test named WHotLAMP for the detection of SARS-CoV-2 in saliva. WHotLAMP is easy to use, very sensitive at 3.6 viral RNA copies per microliter of saliva, specific, and inexpensive. This study is published on the medRxiv*preprint serve.

Study finds no evidence for remdesivir's benefit in severe COVID-19 patients

A new analysis of current data indicates that remdesivir does not show efficacy in regulating the severity of the illness.

SARS-CoV-2 Delta variant likely to become dominant in the United States

Researchers have conducted a study showing that the B.1.1.7 lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that emerged in the UK is now rapidly being displaced as the dominant strain in the United States by the variants of concern B.1.617.2 (Delta) and P.1 (Gamma) that emerged in India and Brazil, respectively.

Research suggests people living with HIV/AIDS may be less susceptible to SARS-CoV-2

Researchers in India have conducted a study showing that the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – was lower among people living with HIV and AIDS than among the general population.

NIH begins study to evaluate how pregnant, postpartum people react to COVID-19 vaccines

A new observational study has begun to evaluate the immune responses generated by COVID-19 vaccines administered to pregnant or postpartum people.

CD39+ monocyte count higher in pregnant than non-pregnant COVID-19 patients

A new study published on the bioRxiv* server describes the changes in the representation of a subset of activated monocytes in this group of patients.

Researchers study COVID-19 immune dysfunction in relation to phosphatidylserine

Often patients suffering from COVID-19 (coronavirus disease) show striking immune dysregulation - causing increased morbidity and mortality. Mechanisms for adaptive immune disturbance, lymphopenia, and thromboinflammation in COVID-19 are still poorly understood.

Increased severity of COVID-19 in pregnancy

A new preprint on the medRxiv* server provides more evidence that COVID-19 likely causes a more serious phenotype to arise in pregnant women.

Epstein-Barr virus reactivation may be the cause of long COVID symptoms

Epstein-Barr virus (EBV) reactivation resulting from the inflammatory response to coronavirus infection may be the cause of previously unexplained long COVID symptoms -- such as fatigue, brain fog, and rashes -- that occur in approximately 30% of patients after recovery from initial COVID-19 infection.
