Brief Summary

Guillain- Barré syndrome (GBS) is an acute inflammatory demyelinating polyneuropathy (AIDP) that often is triggered by an infection. GBS is characterized by progressing weakness and numbness and loss of tendon of reflexes. It can also include tingling sensation in the legs and arms. These symptoms occur due to an autoimmune attack on the myelin resulting in demyelination. The diagnosis is given by electrophysiological examination and clinical presentation. GBS is treated with intravenous immunoglobulin (IVIG) and plasma exchange (PE). Both treatments are equally effective. Most patients recover completely, while others must ease symptoms and reduce the duration of illness by several treatments. The purpose of this study is to define if patients with GBS have higher concentrations of sCD163 in their cerebrospinal fluid and serum compared with symptomatic control subjects. Furthermore it is to define if the concentrations of sCD163 reduces after treatment.

Outcome Measures

Primary Outcomes (1)

  • Concentration of sCD163 in patients with GBS

    Day 1

Secondary Outcomes (1)

  • Concentration of sCD163 in patients with GBS after treatment

    Week 4

Study Arms (2)

Patients diagnosed with GBS

Patients will undergo a lumbar puncture as a part of the diagnostic procedure as soon as they are suspected to be suffering from GBS on clinical grounds with blood test. The procedure and a blood test will be repeated after 6 months. Lumbar puncture Blood sample

Procedure: Lumbar punctureProcedure: Blood Sample

Symptomatic controls

Controls include patients with unspecified neurological symptoms or diseases who will undergo a lumbar puncture at the Department of Neurology at Aarhus University Hospital as part of their diagnostic work up irrespective of this study. We expect to include 40 symptomatic controls.

Procedure: Lumbar punctureProcedure: Blood Sample

Interventions

Lumbar puncture for spinal fluid
