Exploratory clinical and immunological changes following Tixagevimab/Cilgavimab administration in immunodeficient patients with SARS-CoV-2-associated ME/CFS and persistent circulating spike protein Seidel; Anft; Wiemers; Seibert; Bertram; Rosiewicz; Stervbo; Westhoff; Babel BACKGROUND...

Brain-binding auto-antibodies in subjects with and without post-COVID-syndrome after SARS-CoV-2 infection Highlights Seroprevalence of brain binding autoantibodies is increased in the long-term after COVID-19 Post COVID Syndrome does not correlate with the prevalence of NMDAR1 autoantibodies...

Autoantibodies neutralizing type I interferons underlie a third of cases of Chikungunya virus encephalitis or myelitis Chikungunya virus (CHIKV) infection is typically not life threatening but may, in rare cases, affect the central nervous system (CNS). In three cohorts of confirmed CHIKV...

Impact of immunoadsorption on autoantibodies and physical performance in post-COVID patients: a prospective exploratory study of 18 participants PURPOSE Autoantibodies against β-adrenergic and muscarinic acetylcholine receptors are said to play a role in the pathophysiology of post-COVID...

At the Icahn School of Medicine at Mount Sinai, the neuroscientist and long COVID expert David Putrino is collecting blood samples from some of the patients who responded well to Vyvgart. He hopes the samples could enable better immune phenotyping so clinicians can predict whether a person with...

Immunoadsorption Versus Sham Treatment for Post-COVID Syndrome: A Randomised Sham-Controlled Crossover Trial BACKGROUND Post-Covid syndrome is a debilitating condition which may be caused and/or aggravated by autoantibodies. The current study aimed to determine whether autoantibody depletion...

Now published, see post #3. Preprint: Abstract Background: Neurological Long COVID (n-LC) includes persistent cognitive and autonomic symptoms after SARS-CoV-2 infection. Prior studies of post-COVID conditions have described diverse humoral autoreactivity, but findings are heterogeneous, and...

Autoantibodies in long COVID in a black/mixed population compared with recovered and pre-pandemic controls INTRODUCTION Long COVID (LC), a clinical condition marked by persistent and new symptoms after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), affects up to...

Autonomic dysfunction and vasoregulation in Long COVID-19 are linked to anti-GPCR autoantibodies [Line breaks added] Background SARS-CoV-2-triggered autoantibodies (AAB) targeting G protein-coupled receptors (GPCRs) have been suggested to contribute to the post-acute sequelae of COVID-19...

Team from Germany Abstract The objective of this study was to assess the frequency of IgG autoantibodies in patients with fibromyalgia syndrome (FMS), to characterize their binding to dorsal root ganglion (DRG) neurons and glial cells, and to assess whether specific DRG binding patterns...

Aβ low threshold mechanoreceptors contribute to sensory abnormalities in fibromyalgia Fibromyalgia syndrome (FM) is characterized by widespread pain and fatigue. People living with FM also experience tactile allodynia, cold-evoked pain, paraesthesia and dysaesthesia. There is evidence of small...

Autoantibodies mediate pain and sensory dysfunction in post-COVID syndrome Pain and fatigue are common but poorly understood features of post-COVID Syndrome (PCS). To probe the mechanistic basis of these symptoms, we investigated sensory functions in patients with widespread pain attributed to...

Now published, see post #4 Pathogenic IgG from long COVID patients with neurological sequelae triggers sensitive but not cognitive impairments upon transfer into mice Abstract Approximately 30% of long COVID patients still experience neurological symptoms (brain fog, pain, chronic fatigue)...

Autoantibodies against type I interferons are a prominent feature in SARS-CoV-2 fatal disease and hospitalization Rebeca Linhares Abreu Netto, Catherine Chen, Victor Irungu Mwangi, Carlos Eduardo Padron de Morais, Mariana Simão Xavier, Luiz Gustavo Gardinassi, Emily Marie Eriksson, Nicholas...

A multimodal atlas of COVID-19 severity identifies hallmarks of dysregulated immunity The alpha-variant wave of the COVID-19 pandemic provided a unique opportunity to study, at single-cell resolution, how near-universal exposure to the same pathogen can lead to either effective or...

Do self-perpetuating B lymphocytes drive human autoimmune disease? Jonathan C W Edwards, Geraldine Cambridge, Vikki M Abrahams Published: 1999 [Line breaks added] Abstract Normal immunological memory is thought to be underpinned by T lymphocytes. However, in rheumatoid arthritis there are...

Functional Autoantibodies Targeting G-Protein-Coupled Receptors and Their Clinical Phenotype in Patients with Long-COVID Long-COVID (LC) is characterized by diverse and persistent symptoms, potentially mirroring different molecular pathways. Recent data might offer that one of them is mediated...

Long COVID is associated with female sex; Anti-NCAM1 autoantibodies are absent in patients with long COVID Yukiko Motokawa, Jun Sugihara, Tomoya Tateishi, Tadashi Hosoya, Shinsuke Yasuda, Yasunari Miyazaki, Hidehiko Takahashi, Hiroki Shiwaku [Line breaks added] Background Long COVID is a...

This is disapointing… …"This implies that experience of trauma and distress might elicit a specific immune-biological response in genetically or otherwise (eg, past infection, toxicity, trauma) vulnerable individuals, which includes the production of harmful noninflammatory autoantibodies." …...
