Resumo: Immunoadsorption therapy (IAT) using the tryptophan column (TR:TR-350, Asahi Medical Co., Tokyo, Japan) is used for patients with Guillain-Barré syndrome or Fisher's syndrome. Recently, a modified tryptophan column (modified TR:TR-350S, Asahi) was developed to reduce adsorption of fibrinogens. However, it is not clear whether the new column can effectively adsorb the antiganglioside antibodies. We treated 2 patients with Guillain-Barré syndrome, 1 patient with Fisher's syndrome, and 1 patient with Bickerstaff's brainstem encephalitis by IAT using the TR and the modified TR. Samples were taken from the inlet and outlet of the affinity column. We compared the adsorption ability of antiganglioside antibodies between the TR and modified TR. The modified TR adsorbed antiganglioside antibodies less effectively than the TR. No significant bleeding was observed in the patients during each session. Furthermore, results of the clinical study were confirmed by batchwise adsorption test. We propose that the modified TR should not be used for treating patients with Guillain-Barré syndrome and related disorders.
