1/3. Recurrent miller fisher syndrome: clinical and laboratory features and hla antigens.In rare cases, miller fisher syndrome (MFS) has been known to recur. However, clinical features of recurrent MFS have not been well analyzed, and the precipitating factors relating to recurrence remain unknown. From 1981 to 1996, we examined four patients with recurrent MFS among 28 Japanese MFS patients. In the four patients, the recurrent episodes occurred after long asymptomatic intervals, ranging from 2.5 to 12.5 years. The clinical and laboratory features of recurrent episodes were similar either to those of the initial episodes or to those of the 24 non-recurrent patients. Of the two patients tested for serum IgG anti-GQ1b antibody, both were positive. Serological HLA typing showed that all recurrent patients were both HLA-Cw3 and -DR2 positive. However, out of 13 non-recurrent patients examined, six had HLA-Cw3, and four had HLA-DR2. The frequency of HLA-DR2 among the recurrent patients was significantly higher than among healthy controls (corrected P = 0.038), and was also higher than among the non-recurrent patients but not significantly. These findings suggest that recurrent MFS is clinically the same as typical MFS and that HLA-DR2 is possibly associated with recurrence.- - - - - - - - - - ranking = 1keywords = antigen (Clic here for more details about this article) |
2/3. Ataxic polyneuropathy and anti-Pr2 IgM kappa M proteinemia.A case of ataxic neuropathy associated with IgM kappa M proteinemia is reported. Double filtration plasmapheresis effectively treated the neuropathy. The IgM kappa antibody had anti-Pr2 cold agglutinin activity. We demonstrated reactivities of the IgM kappa antibody to sialosyl paragloboside, sialosyl lactosaminyl paragloboside, GT1b, GD1a, GD1b, GM3 and GD3 on high-performance thin-layer chromatography immunostaining and enzyme-linked immunosorbent assay, which is previously unreported antigenic specificity of the M proteins in cases of paraproteinemic neuropathy. IgM M protein with anti-Pr2 cold agglutinin activity may play a pathogenetic role in peripheral nerve demyelination, because the target antigens of the M protein are present in myelin and possibly in endothelial cells of the peripheral nervous system.- - - - - - - - - - ranking = 0.5keywords = antigen (Clic here for more details about this article) |
3/3. 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.- - - - - - - - - - ranking = 1.5keywords = antigen (Clic here for more details about this article) |
