Ability to remove immunoglobulins and antiganglioside antibodies by double filtration plasmapheresis in Guillain-Barré syndrome: is it equivalent to plasma exchange?
The value of plasma exchange (PE) in Guillain-Barré syndrome (GBS) is well established. In Japan, patients with GBS and related diseases often receive double filtration plasmapheresis (DFPP) as well as PE. No comparative trials between PE and DFPP, however, have been conducted. We compared their abilities to remove immunoglobulins and antiganglioside antibodies to find out whether DFPP is equivalent to PE. The ability to remove immunoglobulins and antiganglioside antibodies was compared between PE and DFPP using plasma samples from 41 patients with GBS and related diseases before and after each treatment session. The ability of DFPP to remove both IgGs and antiganglioside IgG antibodies were significantly inferior to those of PE. There is a less theoretical basis for selecting DFPP as the first choice of plasmapheresis for GBS and related disorders.
