This case report details a 57-year-old man with ulcerative colitis who developed chronic polyneuropathy. The findings suggest a potential autoimmune link between the inflammatory bowel disease and the peripheral nerve disorder.

Area of Science:

  • Neurology
  • Gastroenterology
  • Immunology

Background:

  • Ulcerative colitis (UC) is a chronic inflammatory bowel disease.
  • Peripheral neuropathies can be associated with systemic inflammatory conditions.

Observation:

  • A 57-year-old male patient with UC presented with distal sensory disturbances and muscle weakness in all four extremities.
  • Neurological examination revealed sensory impairment, distal muscle atrophy and weakness, and diminished reflexes.
  • Laboratory tests showed elevated inflammatory markers (ESR, CRP) and immunoglobulins (IgG, IgM).
  • Cerebrospinal fluid analysis indicated elevated protein and IgG.
  • Nerve conduction studies demonstrated delayed sensory nerve conduction velocities.
  • Sural nerve biopsy revealed myelin sheath degeneration and loss of large fibers, with evidence of demyelination on teased nerve analysis.

Findings:

  • The patient's clinical presentation and diagnostic findings are consistent with chronic inflammatory demyelinating polyneuropathy.
  • The neuropathy's characteristics suggest a potential autoimmune etiology shared with ulcerative colitis.

Implications:

  • This case highlights a potential association between ulcerative colitis and peripheral neuropathy.
  • Further research into the shared autoimmune pathogenesis may offer new therapeutic targets for both conditions.
