[Brucellosis and acute inflammatory polyradiculoneuropathy].

Three patients with Guillain-Barré syndrome (GBS) during active brucellosis are reported: in one of them, who had an unfavorable outcome, the clinical features, the neurophysiological studies and the sural nerve biopsy were consistent with the axonal form of GBS. In the remaining two patients, who had a satisfactory course, the neurophysiological studies and the sural nerve biopsy disclosed the demyelinating character of the disease. We agree with other authors that the axonal and demyelinating forms of GBS should be separated, in view of their different clinical and possibly pathogenetic implications, both in GBS in general and in the form associated with brucellosis.
