Lymphopenia News and Research

RSS

Lymphopenia is a condition in which there is a lower-than-normal number of lymphocytes (a type of white blood cell) in the blood. Also called lymphocytic leukopenia and lymphocytopenia.

Clinical trials during a pandemic – lessons from COVID-19

In this interview, Dr. Benedicte Roquebert, Dr. Stephanie Haim-Boukobza and Dr. Souad Mehlal discuss how COVID-19 has resulted in new ways to think about clinical trials during a pandemic.

Oxygen therapy may improve hypoxia-induced B cell abnormalities in COVID-19

Researchers in the United States have demonstrated early and persistent B cell abnormalities in patients with moderate or severe coronavirus disease 2019 (COVID-19) that may be largely driven by hypoxia.

Serum testosterone status recovery an accurate predictor of survival in male COVID-19 patients

In a study available on the medRxiv* the preprint server, researchers from Spain showed that testosterone trajectories are very accurate individual predictors of survival in male patients with COVID-19. To better understand the relationship between testosterone levels and disease severity, they studied a group of male and female COVID-19 patients assessing their serum and blood biomarkers in association with outcome of disease.

Could microalgae-derived antiviral compounds combat SARS-CoV-2 and other viruses?

A new review article published in the journal Antibiotics reports the presence of a large number of bioactive compounds in microalgae that target chemical structures present only in their structure.

Is COVID-19 more severe in pregnancy?

A new study, released as a preprint on the medRxiv* server, indicates that pregnant women are more likely to develop severe disease following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

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.

Can convalescent plasma therapy improve COVID-19 outcomes in patients with hematologic cancers?

A recent study discusses the findings of a study on patients with hematologic cancers who received convalescent plasma therapy following their diagnosis of COVID-19.

Could a fungus-derived compound reduce hyperinflammation in severe COVID-19?

New research from scientists at the University of Pennsylvania, USA, demonstrates that cyclosporine A (CSA), a calcineurin inhibitor that modulates cytokine production, may have potential antiviral properties against coronaviruses.

Pathogenic airway neutrophilia drives ARDS in Black patients with severe COVID-19 in case study

Researchers from the US used a systems immunology approach where they combined high-dimensional flow cytometry and multi-omics single-cell sequencing analyses of immune profiles taken from the airways and matching blood samples of Black/AA patients.

What lessons have we learned over a year into the COVID-19 pandemic?

One of the pressing questions scientists are currently trying to answer is whether the current vaccines will remain effective against the emerging SARS-CoV-2 variants of concern. A new piece of research has been published in the journal Biomedicines, which discusses the knowledge we have gained thus far and the questions that researchers should address in future work.

Could the intranasal route be an alternate avenue of COVID-19 vaccination?

A new study has been published in the journal Vaccines that summarizes the history of vaccines, reviews the current progress in COVID-19 vaccine technology, and discusses the status of intranasal COVID-19 vaccines as a potential pathway to immunization.

Intensity and duration of SARS-CoV-2 immunity may depend on ABO blood group

A team of scientists from Canada and Spain recently evaluated the durability of antigen-specific immune responses in COVID-19 recovered individuals. They have also identified potential host factors associated with robust and long-lasting anti-SARS-CoV-2 immunity.

The potential therapeutic value of CDK6 inhibitors in critical COVID-19

While drug repurposing has been explored in the context of the current coronavirus disease 2019 (COVID-19) pandemic, the success of this strategy has been limited so far. A new study, released as a preprint on the medRxiv* server, describes a new method of identifying a promising hit among drugs already in use.

Facets of SARS-CoV-2 infection and animal models

A new study in the journal Frontiers in Cell and Developmental Biology discusses the ribonucleic acid (RNA) genome of the virus, and the mechanisms by which it establishes infection within the host cell. The researchers also summarize the development of animal models of COVID-19, which will both help understand the clinical features of the illness, and indicate new approaches for the treatment of the infection.

Severe COVID-19 linked to genetic clotting predisposition

Thus, the need to stratify the risk of severe or critical disease in patients presenting with SARS-CoV-2 infection remains a crying necessity. A new preprint research paper posted to the medRxiv server discusses the relationship between severe disease and pre-existing susceptibility to clots and other diseases of the cardiovascular system.

SARS-CoV-2 infection prolongs viral shedding and lymphocyte loss in patients with cancer

Patients with cancer have a more challenging time with infections while undergoing treatment — placing them as high-risk for severe COVID-19 illness and death. However, how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interacts with cancer therapies remains poorly understood.

Transplant recipients with COVID-19 may show lower cellular and antibody immune responses

Transplant patients are typically on chronic immunosuppression, making them automatically more vulnerable to infection with SARS-CoV-2, the agent responsible for the loss of over three million lives in the current COVID-19 pandemic. A new study discusses evidence for subnormal immune responses following COVID-19 in this population.

Aberrant immune features in healthy elderly and male subjects with severe COVID-19 may predate infection

A new study shows that the immunological features of severe COVID-19 are already present in healthy older adults and in men, before they are infected, indicating a possible explanation for this differential susceptibility towards the virus.

Pregnancy may increase the risk of COVID-19 severity

Against the background of the COVID-19 pandemic, the impact of SARS-CoV-2 infection in pregnancy has been a subject of much controversy. In order to help answer the question as to whether this infection causes significant harm in pregnancy, a new study, released as a medRxiv* preprint, reports on the disease outcomes of this infection in pregnant women.

Class I HLA alleles shape CD8+ T cell repertoire in SARS-CoV-2 infection

An interesting new study discusses how adaptive cellular immunity against the SARS-CoV-2 is dependent on differences in HLA-encoding genes between patients.
