Campylobacter jejuni O:19 serotype-associated Guillain-Barré syndrome in a child: the first case reported from Greece.

We present a case of Guillain-Barré syndrome (GBS) following Campylobacter jejuni HS serotype O:19 infection in a child. Antibodies against C. jejuni and autoantibodies to the peripheral nerve gangliosides GM1 were positive, a pattern correlating well with the existence of an inflammatory neuropathy like GBS. The patient shared the HLA-B35 and HLA-DR8 antigens, which have been found to be increased in GBS patients with previous C. jejuni infection. As this is the first diagnosed C. jejuni-associated GBS case reported from Greece, further clinical and epidemiologic investigations are warranted.
