Further humoral immunity evasion of emerging SARS-CoV-2 BA.4 and BA.5 subvariants
The Lancet – SARS-CoV-2 BA.4 and BA.5 lineages have been the dominant strains in most regions worldwide and are continuously gaining mutations in the receptor-binding domain. Multiple BA.4 and BA.5 subvariants with Arg346 mutations in the spike glycoprotein have been identified in various countries, such as BA.4.6, BF.7, BA.5.2.6, BA.4.1.9, and BE.1.2 harbouring Arg346Thr; BA.4.7 […]

Host and viral proteins involved in SARS-CoV-2 infection differentially bind heme
PubMed – In most severe cases, SARS-CoV-2-induced autoimmune reactions have been associated with hemolytic complications. Hemolysis-derived heme from ruptured red blood cells has been shown to trigger a variety of fatal proinflammatory and procoagulant effects, which might deteriorate the progression of COVID-19. In addition, the virus itself can induce proinflammatory signals via the accessory protein […]

Long COVID Has Forced a Reckoning for One of Medicine’s Most Neglected Diseases
The Atlantic – Only a couple dozen doctors specialize in chronic fatigue syndrome (ME/CFS). Now their knowledge could be crucial to treating millions more patients. ME/CFS involves a panoply of debilitating symptoms that affect many organ systems and that get worse with exertion. The Institute of Medicine estimates that it affects 836,000 to 2.5 million people in the […]

A practical update on the management of patients with COVID–19
Royal College of Physicians – While vaccines against COVID-19 are being rolled out, an ongoing need remains for therapies to treat patients who have symptomatic COVID-19 before vaccination or in whom breakthrough infection develops. Dexamethasone and interleukin-6 inhibitors have been the mainstay of treatment for severe to critical COVID-19 requiring hospitalisation. However, in the previous […]
