[Ischemic resistance of motor axons in children with viral meningitis and Guillain-Barré syndrome].

The effect of temporal local ischemia at the forearm on ulnar motor nerve conduction velocity in the control (n = 26 children), group of patients with acute period viral meningitis (VM) (n = 16 children), 14 days after the clinical manifestation of VM (n = 11 children) and children with Guillain-Barre syndrome (GBS) in catamnesis (n = 11 children) was evaluated. Less pronounced reactivity of neural conduction on ischemia for 10 minutes (by 50%, p < 0.00001), was seen in children with GBS in catamnesis, comparing to the controls. In the acute period VM also less pronounced reactivity of neural conduction by 29%, than in the controls, was registered. We propose, that ischemic resistance in immune-mediated neuropathy and in the acute period of infection may happen due to cytokine-mediated channelopathy.
