Guillain-Barré syndrome associated with inappropriate secretion of antidiuretic hormone following SARS-CoV-2 infection: A case-report.

In a system already preconditioned by previous damage, as results of the cytokine release syndrome complicating the COVID-19 disease, a small trigger may be sufficient to develop a SIADH complicating a GBS, even without a poor outcome.

Guillain-Barré syndrome after AstraZeneca COVID-19-vaccination: A causal or casual association?

We report a case of Guillain-Barré syndrome (GBS) following the first dose of Oxford/AstraZeneca COVID-19 vaccine with papilledema as atypical onset. As the COVID-19 vaccination campaign progresses worldwide, GBSs vaccine-related have been increasingly reported. After reviewing the available literature, considering the annual incidence of GBS, in this historical moment, the public health systems cannot afford an unjustified distrust in vaccines, caused by misinterpretation of epidemiological data. Nonetheless, it is important for clinicians to promptly recognize neurological complications potentially associated with COVID-19 vaccinations and report them to pharmacovigilance agencies.
