[Cerebrospinal fluid parameters in Guillain-Barré polyradiculitis. Importance of barrier disorder and intrathecal immunoglobulin synthesis].

With routine CSF determination of 21 patients with GBS the BBB and the intrathecal IgG synthesis was investigated when calculated CSF/serum albumin ratio and CSF IgG-index respectively. Only in 2 of 21 patients (9.5%) an intrathecal IgG synthesis and in 14 of 21 patients (67%) a BBB damage was found. The BBB was considered as an important pathogenetic factor in GBS. A hypothesis for the development of the albumino-cytological dissociation is presented.
