Abstract:
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection
attacks the respiratory and nervous systems. Among patients with SARS-CoV-2 infection,
cases with simultaneous central and peripheral nervous system damage are rare, and those with
intractable hypophosphatemia and hypokalemia complicating the former have not been reported
yet.
Case Presentation: A 59-year-old woman presented to the emergency department with incoherent
speech evolving for 3 days. She had tested positive for the SARS-CoV-2 RT-PCR assay 8
days earlier. Her physical examination showed progressive limb weakness with diminished tendon
reflexes and normal sensory examination. Cranial MRI revealed multiple abnormal signals
in the brain. Cerebrospinal fluid (CSF) analysis and electromyography revealed acute motor
axonal neuropathy (AMAN), further diagnosed as encephalitis combined with GuillainBarré
syndrome (GBS). The patient received glucocorticoid therapy, intravenous immune globulin
(IVIG), and rehabilitation therapy. The patient experienced an intractable hypophosphatemia
and hypokalemia during the treatment period, which was not effectively corrected several times.
The symptoms improved after 1 month of treatment.
Conclusion: Early diagnosis is important for the management of Guillain-Barré syndrome associated
with SARS-CoV-2 infection. Moreover, in order to prevent life-threatening long-term
persistent electrolyte disturbances in non-seriously ill patients, clinicians should pay particular
attention to their electrolyte status.
