COVID-19–Related GBS Correspondence Letters

References	Title	Question	Conclusion
Gupta et al22	Is COVID-19–related Guillain-Barré syndrome different?	How does COVID-19–related Guillain-Barré syndrome compare against other presentations of GBS?	Anti-ganglioside antibody was not found in patients with COVID-19– and Zika virus–related GBS. The neuropathy in viral infections–related GBS could be due to other autoantibodies that are not detected as yet or the viruses produced nerve damage due to other neurotoxic effects
Cappello8	COVID-19 and molecular mimicry: the Columbus’ Egg?	Does molecular mimicry explain both the acute pulmonary embolism and the multi-organ microvascular thrombosis that some patients experience?	It would be appropriate if this Journal would stimulate the scientific community on the fact that molecular mimicry phenomena can occur in SARS-CoV-2 It is also urgent to start the search for human epitopes that turn into autoantigens, and to remind this risk to all those who are currently working on vaccines
Gigli et al23	Guillain‑Barré syndrome in the COVID‑19 era: just an occasional cluster?	Compare the frequency of GBS cases during the March-April months of the last 3 y and to admissions for GBS during the same months of the current year in Friuli Venezia-Giulia, Italy	Compared with years 2017-2019, the increase of GBS cases in 2020 is 5.41-fold The suspicion that this striking difference could be due to the pandemic curve in our region is, therefore, legitimate

COVID-19 indicates Coronavirus Disease 2019; GBS, Guillain-Barré syndrome; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
