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.

COVID-19 patient with repeatedly undetectable SARS-CoV-2 antibodies

A recent case study published in the Journal of Applied Laboratory Medicine in August 2020 illustrates this with its finding of persistent seronegativity in a patient confirmed to be SARS-CoV-2 positive.

Severe fatigue common in COVID-19, independent of disease severity

Patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection often complain of fatigue, but now a new study shows that it also causes severe and frequent fatigue in those who recover after mild illness too.

Dysfunctional T cells present at high levels in severe COVID-19

Now, a new study by researchers at Saarland University, Germany, and published on the preprint server medRxiv in July 2020 shows that there are higher levels of anti-SARS-CoV-2 T cells, which show significant alterations in the phenotype and function.

Immune response variations across the COVID-19 spectrum

A new study published on the preprint server medRxiv in June 2020 describes differences in the adaptive and innate immune response in mild, moderate, and severe COVID-19. This may mean that permanent immune responses occur only in patients who recover from severe COVID-19.

SARS-CoV-2 induces broad T cell response in recovering patients

A new study published on the preprint server bioRxiv in June 2020 shows that T cell responses in COVID-19 patients are broader and more robust in severe disease and are explicitly directed against spike, memory, and ORF3a proteins.

Balanced B and T cell response required to control SARS-CoV-2

A new study by researchers in the Netherlands and published on the preprint server bioRxiv in June 2020 describes the differences in T and B cell responses seen in patients with severe COVID-19.

Females mount stronger T-cell response to SARS-CoV-2

A new study published on the preprint server medRxiv in June 2020 shows that immune cells, antibody levels, cytokine levels, and viral loads contribute to the sex difference seen in response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

High mortality rates among coronavirus-positive dialysis patients

Spain is one of the European countries besides the UK and Italy that was particularly hard hit by the coronavirus pandemic in March.

Genetic variations linked to COVID-19 severity

A new report by researchers from Thailand's Mahidol University and published on the preprint server medRxiv in May 2020 reports that the clinical severity of COVID-19 may be linked to the genetic makeup of the patient in addition to external factors.

Ruxolitinib shows promise in severe COVID-19

An anti-inflammatory drug Ruxolitinib has shown promising results in the treatment of severe coronavirus disease COVID-19. The study titled, “Ruxolitinib in treatment of severe coronavirus disease 2019 (COVID-19): A multicenter, single-blind, randomized controlled trial,” was published as a pre-proof for the Journal of Allergy and Clinical Immunology.

Adoptive T-cell therapy targeting MAGE-A4 achieves responses in patients with multiple solid tumors

The adoptive T-cell therapy ADP-A2M4, which is engineered to express a T-cell receptor (TCR) directed against the MAGE-A4 cancer antigen, achieved responses in patients with multiple solid tumor types, including synovial sarcoma, head and neck cancer and lung cancer, according to results from a Phase I clinical trial led by researchers at The University of Texas MD Anderson Cancer Center.

Transgenic mouse model of HLH may play key role in saving lives during COVID-19

A transgenic mouse developed at Cincinnati Children's to model the deadly childhood immune disease HLH (hemophagocytic lymphohistiocytosis) may play a key role in saving lives during the COVID-19 virus pandemic.

Blood clotting disorders may explain some of the worst symptoms of COVID-19

The hypothesis that blood clotting disorders may explain some of the worst symptoms of COVID-19, including respiratory failure and pulmonary fibrosis, was suggested in mid-April by researchers in Brazil affiliated with the University of São Paulo's Medical School (FM-USP) via an article accepted for publication by the Journal of Thrombosis.

Study demonstrates dynamic and broad-scale immune alterations in COVID-19 patient

A new case report released on the preprint server medRxiv* provides a detailed longitudinal analysis of the immune response associated with a fatal case of coronavirus disease (COVID-19). It highlights the need for addressing the source of hyper inflammation in the treatment approach.

Hypertensive patients on ACE inhibitors and angiotensin receptor blockers may have improved COVID-19 prognosis

Emerging concerns that common antihypertensive treatment approaches with angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) – jointly known as renin-angiotensin-aldosterone system (RAAS) inhibitors – may exert a negative effect in COVID-19 patients are not grounded in scientific evidence, as reported by researchers in a recent review article published in Mayo Clinic Proceedings journal.
