Management of Guillain-Barré Syndrome Associated with Infection

Diagnostic Workup

The American College of Physicians recommends obtaining neurology consultation to guide the diagnostic approach and management for patients with Guillain-Barré Syndrome (GBS) associated with infection 1
The American Academy of Neurology suggests performing MRI of spine with and without contrast to rule out compressive lesions and evaluate for nerve root enhancement/thickening in patients with GBS 1
The American College of Physicians recommends conducting lumbar puncture with CSF analysis for cell count, differential, cytology, protein, glucose, and cultures to diagnose GBS 1
The American Academy of Neurology recommends testing for serum antiganglioside antibodies for GBS and its subtypes (e.g., anti-GQ1b for Miller Fisher variant) 1
The American College of Physicians suggests performing electrodiagnostic studies (NCS and EMG) to evaluate polyneuropathy in patients with GBS 1
The American Academy of Neurology recommends screening for reversible neuropathy causes: HbA1c, vitamin B12, TSH, vitamin B6, folate, serum protein electrophoresis, and immunofixation in patients with GBS 3

The American College of Cardiology recommends administering IVIg 0.4 g/kg/day for 5 days (total dose 2 g/kg) as first-line immunotherapy for patients with GBS 1
The American Academy of Neurology suggests performing plasmapheresis (5 sessions over 1-2 weeks) as an alternative to IVIg for patients with GBS 1
The American College of Physicians recommends that corticosteroids alone are not recommended for idiopathic GBS, but may be considered for immune checkpoint inhibitor-related GBS (methylprednisolone 2-4 mg/kg/day) 1

The American Thoracic Society recommends performing frequent neurological assessments and pulmonary function monitoring for patients with GBS 1
The American Academy of Neurology suggests using the "20/30/40 rule" to assess respiratory failure risk: patient is at risk if vital capacity <20 ml/kg, maximum inspiratory pressure <30 cmH₂O, or maximum expiratory pressure <40 cmH₂O 4
The American College of Physicians recommends monitoring for concurrent autonomic dysfunction (heart rate, blood pressure, bowel and bladder function) in patients with GBS 1
The American Academy of Neurology suggests implementing nonopioid management of neuropathic pain with pregabalin, gabapentin, or duloxetine for patients with GBS 1

The American College of Physicians recommends implementing preventive measures for pressure ulcers, hospital-acquired infections, and deep vein thrombosis for patients with GBS 4
The American Academy of Neurology suggests addressing specific GBS complications such as inability to swallow in patients with bulbar palsy, corneal ulceration in patients with facial palsy, and limb contractures 4
The American College of Physicians recommends avoiding medications that can worsen neuromuscular function, such as β-blockers, IV magnesium, fluoroquinolones, aminoglycosides, and macrolides in patients with GBS 5

The American Academy of Neurology reports that about 40% of patients do not improve in the first 4 weeks following treatment, which doesn't necessarily indicate treatment ineffectiveness 4
The American College of Physicians recommends considering repeating the full course of IVIg or plasma exchange for treatment-related fluctuations (occurring in 6-10% of patients within 2 months of initial improvement) 4

The American Academy of Neurology reports that approximately 80% of patients regain walking ability at 6 months after disease onset 2
The American College of Physicians states that mortality occurs in 3-10% of cases, most commonly due to cardiovascular and respiratory complications 2
The American Academy of Neurology notes that up to two-thirds of deaths occur during the recovery phase, so continued vigilance is necessary even after apparent improvement 4
