A case of brucellosis-induced Guillain–Barre syndrome

Guillain–Barre syndrome (GBS) is a rare neurological complication of brucellosis, and neurobrucellosis is the most common, but they have many similarities in clinical manifestations. Many clinicians are accustomed to merely explaining the manifestations of nervous system involvement with neurobrucellosis, but they ignore the possibility of GBS, and this leads to misdiagnosis, untimely treatment, and serious consequences.

A 55-year-old male patient was admitted to The First Affiliated Hospital of Harbin Medical University for intermittent fever, fatigue, and waist pain more than three months. Brucellosis was diagnosed from the blood test. Although anti-brucella treatment was given at the time of diagnosis, the disease continued to progress. At the time of the cerebrospinal fluid systematic physical examination and the neuroelectrophysiological test, acute motor sensory axonal neuropathy was diagnosed. The patient was given immediately administered immunoglobulin therapy. After three months of systemic treatment, the patient's muscle strength of the distal limbs gradually recovered. The numbness of the limbs eased slowly, and urination function and respiratory function returned to normal. He could sit by himself.

The possibility of GBS should be closely monitored for when a brucellosis patient shows typical clinical manifestations of progressive muscle weakness, protein-cell separation of the cerebral spinal fluid, and typical demyelinating sensorimotor polyneuropathy.
