Coronavirus disease 2019 (COVID-19) is a significant cause for intensive care unit (ICU) admission worldwide. Most COVID-19 infections are associated with lower respiratory abnormalities but it has been increasingly associated with extra-pulmonary manifestations. Guillain–Barre syndrome (GBS) is a rarely diagnosed but severe disease associated with COVID-19 infection. We describe the diagnostic process behind diagnosing GBS in an elderly male who developed acute-onset quadriparesis and respiratory muscle failure associated with severe COVID-19 pneumonia in a military ICU. A 69-year-old male was admitted to the ICU for acute hypoxemic respiratory failure due to COVID-19 pneumonia. He was subsequently intubated and treated with dexamethasone and remdesivir with improvement. On hospital day 32, the patient was extubated. Three days later, he developed acute, symmetric limb quadriparesis and respiratory muscle failure requiring reintubation. Analysis of his cerebrospinal fluid showed a cytoalbuminologic dissociation, and electromyography/nerve conduction study showed slowed nerve conduction velocity. These findings are consistent with GBS. Blood cultures, serum polymerase chain reaction testing, and clinical symptoms were not suggestive of other common pathogens causing his GBS. The patient’s acute GBS in the setting of recent severe COVID-19 infection strongly suggests association between the two entities, as supported by a growing body of case literature. The patient was subjected to intravenous immunoglobulin treatment and was discharged with greatly improved strength in the upper and lower extremities. Our goal in describing this case is to highlight the need for providers to consider, accurately diagnose, and treat GBS as a consequence of severe COVID-19 infection.
