    This study aimed to describe the neurological improvements in a patient with severe long COVID brain dysfunction following perispinal etanercept administration. Perispinal administration of etanercept, a novel method designed to enhance its brain delivery via carriage in the cerebrospinal venous system, has previously been shown to reduce chronic neurological dysfunction after stroke. Etanercept is a recombinant biologic that is capable of ameliorating two components of neuroinflammation: microglial activation and the excess bioactivity of tumor necrosis factor (TNF), a proinflammatory cytokine that is a key neuromodulator in the brain. Optimal synaptic and brain network function require physiological levels of TNF. Neuroinflammation, including brain microglial activation and excess central TNF, can be a consequence of stroke or peripheral infection, including infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19.

    I expect there would be plenty of volunteers from the ME community who would be willing to give this a try. If it doesn't help significantly, at least it would eliminate some theories.

    Nancy Klimas is trialing Etanercept and Mifepristone in GWI, though presumably not with this special injection method.

    I think etanercept has been tried in ME before with no useful effect.

    Perispinal administration sounds highly risky to me and unjustified in the absence of any evidence of inflammation.
