[Prolonged Guillain-Barré syndrome]

Area of Science:

• Neurology
• Immunology

Background:

• Guillain-Barré syndrome (GBS) in children typically has a favorable prognosis.
• Severe and prolonged GBS cases, including cranial nerve and autonomic dysfunction, require intensive management.

Observation:

• A 12-year-old boy presented with rapidly ascending, slowly progressive GBS.
• Diagnosis confirmed by clinical signs, EMG, CSF analysis, and anti-GM1 antibodies.
• Initial treatment with intravenous immunoglobulin (IVIG) yielded slow improvement.

Findings:

• A second IVIG infusion two months later resulted in satisfactory recovery of motor, sensory, and autonomic functions.
• A third IVIG course provided minimal additional benefit.
• Five months post-onset, residual flaccid paralysis persists, but autonomic instability resolved.

Implications:

• Repeated IVIG may benefit prolonged GBS, but optimal intensive care is crucial.
• Further research into treatments like beta-interferon and immunosuppressants is warranted for severe GBS.
• This case underscores the complex management and variable treatment response in pediatric GBS.
