Guillain-Barré syndrome following bacterial meningitis: a case report and literature review.

BACKGROUND: We reported a case of an adult that presented Guillain-Barré syndrome (GBS) after bacterial meningitis which was secondary to chronic suppurative otitis media (CSOM). To our knowledge, this is the first case involving an adult presenting with GBS following bacterial meningitis.

CASE PRESENTATION: A 46-year man with type 2 diabetes and otitis media (OM) suffered with fever, headache, and vomiting for 6 days. The patient's neck stiffness was obvious and the Kernig and Brudzinski signs were produced. The result of cerebrospinal fluid (CSF) analysis and cytological examination of the CSF supported the diagnose of bacterial meningitis. On day 17 the patient felt numbness in both hands and feet, which gradually progressed to weakness of the limbs. Bladder dysfunction occurred, which required catheterization. The patient showed a tetraparesis with emphasis on the legs. The deep tendon reflexes of limbs were absent. The patient had peripheral hypalgesia and deep sensory dysfunction. The symptoms were possibly a result of GBS. Nerve conduction study showed that the F wave latency of the upper and lower limbs was prolonged, particularly the lower limbs. 8 days later the repeated nerve conduction study showed a low compound muscle action potential (3.3 mV) with a normal distal motor latency (14.2 ms) and a low motor nerve conduction velocity (34.3 m/s) in the tibial nerve. The patient still required assistance when walking 3 months after onset.

CONCLUSIONS: GBS following bacterial meningitis is rare and limbs weakness in patients with bacterial meningitis was usually considered because of weakness. This case should serve as a reminder for clinical doctors that when a patient with bacterial meningitis complains about limbs numbness or weakness, GBS should be considered, especially when the patient had diabetes mellitus (DM) history.
