Clinical study of Guillain-Barre syndrome combined with demyelinating lesion in central nervous system / 临床神经病学杂志

ABSTRACT

Objective To investigate Guillain Barre syndrome (GBS) combined with demyelinating neuropathy in central nervous system(CNS), and explore the possible mechanism and the relationship between the two.Methods 3 cases GBS combined with demyelinating neuropathy in CNS were observed clinically and the datum of laboratory were analysed.Results Case 1, a 28 year old man had symptoms of general flaccid paralysis and coma.The result of blood gas analysis was normal. CSF showed an albuminocytological dissociation, delayed nerve conduction velocity and missed F waves. Brain MRI showed multifocal T 2 Wight Image high signs in white matter of bilateral brain and cervical spinal cord. The patient is getting recovery by treatment with plasma and immunoglobulin. Case 2 , a 5 year old girl with progressive weakness of her limbs and respiratory arrest, appeared confusion,dully light reflex and absent corneal reflex, at last she died because of rejecting treatment.Case 3,a 12 year old boy with progressive weakness of his limbs and the difficult of relieving the bowels.Brain MRI was normal.Spinal MRI showed multifocal T 2 weight imagine hight signs from T 5 to L 4.CSF showed an albuminocytological dissociation.EMG showed a delayed nerve conduction velocity.Conclusion GBS combined with disorders of consciousness are mostly severe, the pathological mechanism is unclear. It is suggested that auto immunoreaction caused by P 1 myelin basic protein can relate to around and CNS demyelination.
