Systemic lupus erythematosus presenting with recurrent acute demyelinating polyneuropathy

Area of Science:

• Neurology
• Immunology
• Rheumatology

Background:

• Acute Guillain-Barré syndrome is an immune-mediated disorder affecting peripheral nerves.
• Systemic lupus erythematosus is a chronic autoimmune disease with diverse clinical presentations.

Observation:

• A patient presented with three distinct episodes of acute demyelinating neuropathy over three years.
• Each episode met the diagnostic criteria for acute Guillain-Barré syndrome.
• Episodes were separated by 1-2 years, with near-complete clinical recovery after each.

Findings:

• Strong serological evidence of lupus erythematosus was present during each episode.
• Pleural effusion was the only systemic feature observed, occurring in the last two episodes.
• This suggests a potential link between lupus erythematosus and recurrent Guillain-Barré syndrome.

Implications:

• This case underscores the importance of considering autoimmune conditions like lupus in recurrent neurological presentations.
• Further research may elucidate the specific mechanisms linking lupus erythematosus and Guillain-Barré syndrome.
• Understanding this association can improve diagnostic and therapeutic strategies for patients with overlapping conditions.
