One of the most important layers of our body’s defense against SARS-CoV-2 lies in our innate immune system. The innate immune system protects our body from microbes, viruses, bacteria, and parasites that we have not previously encountered. While much of public attention and awareness of human immunity is focused on adaptive or learned immunity, innate
Evidence from the SARS-CoV-1 outbreak of 2002 to 2004 shows that lung abnormalities may remain detectable even after decades, but do not show any progression, according to study co-author Leonhard Gruber, MD, from the Department of Radiology at Innsbruck Medical University. Recent studies, though, have shown a risk of progression of lung abnormalities such as
Symptoms persisted for months after a positive test for COVID-19 Adding to a growing body of evidence that, for many, problems related to COVID-19 linger longer than the initial infection, researchers at Washington University School of Medicine in St. Louis have found that some people infected during the pandemic’s early months experienced peripheral neuropathy —
Platelet-activating anti-PF4 antibodies in VITT are transient in >90% of patients. Likely VITT patients can safely receive a second vaccination shot with an mRNA vaccine, independent of their VITT-antibody status. Vaccine-induced thrombotic thrombocytopenia (VITT) is triggered by vaccination against COVID-19 with adenovirus vector vaccines (ChAdOx1 nCoV-19; Ad26.COV2-S). In this observational study, were followed VITT patients
A combination of the delta (AY.4) and BA.1 omicron variants has been named by the World Health Organization as the BA.1 x AY.4 recombinant. First detected in France in January 2022, it has since picked up the nickname “deltacron”1 How does a recombinant emerge? Recombinants can emerge when multiple variants infect the same person at
A new Expert Consensus Decision Pathway released by the ACC addresses the evaluation and management of some of the more common cardiovascular sequelae in adults with COVID-19. The Pathway, published March 16 in the Journal of the American College of Cardiology, specifically addresses myocarditis and other types of myocardial involvement, patient-centered approaches for long COVID, and
People who have had Covid-19 are at increased risk of developing type 2 diabetes. This is the result of a study by DDZ, DZD and IQVIA, which has now been published in Diabetologia. Studies show that the human pancreas can also be a target of the SARS-CoV-2 (severe acute respiratory syndrome coronavirus type 2 virus). Following
UC San Diego study identifies lung neuroendocrine cells as drivers of developmental lung disease; similar mechanism may contribute to COVID-19 symptoms COVID-19 has put a spotlight on the pulmonary and nervous systems, but there is still much to learn about how they interact. Researchers at University of California San Diego School of Medicine recently explored
The world’s largest study of the genetics of critical Covid-19, involving more than 57,000 people, has revealed fresh details about some of the biological mechanisms behind the severe form of the disease. Some 16 new genetic variants associated with severe Covid-19, including some related to blood clotting, immune response and intensity of inflammation, have been
More than three times as many people may have died worldwide as a result of the pandemic than official COVID-19 death records suggest, according to an analysis published in The Lancet. While the official COVID-19 death toll was 5.9 million between January 1, 2020, and December 31, 2021, the new study estimates 18.2 million excess deaths
