Fisher syndrome after Campylobacter jejuni enteritis: human leukocyte antigen and the bacterial serotype.

We describe two children who had Fisher syndrome subsequent to Campylobacter jejuni enteritis. The C. jejuni isolates from both patients, who lived in different areas, belonged to PEN 2: LIO 4. One patient had the following human leukocyte antigens (HLAs): HLA-A24, 33; B44, 52; DQ1; and DR2, 6 antigens. Another had the HLA-A24, 33; B44, 54; Cw1; DQ1, 4; and DR4, 6. An effort should be made to isolate C. jejuni from patients with Fisher syndrome and to perform HLA typing so that the pathogenesis of this syndrome can be clarified.
