Mean values of myasthenia gravis score and titer of anti-AChR antibodies in the 11 improved patients after immunoadsorption therapy. Consecutive immunoadsorption treatments induced a significant fall of the myasthenia gravis score and a decrease in the titer of AChR antibodies. The myasthenia gravis score remained low even on day 42 despite the rise in AChR antibody titers.

Sixty-three Guillain-Barré Syndrome (GBS) patients were enrolled. These patients were treated with plasma adsorption (PA, n=39: Immusorba TR-350), plasma exchange (PE, n=14), or immunoglobulin treatment (IVIg, n=10). The number of days required for one or two functional grades improvement was 20.3 ±15.3 or 34.8 ± 20.5 days, respectively. Treatment methods (PA, PE, or IVIg) did not significantly influence the outcome. Since PA does not result in a risk of unknown infection, choosing a PA may be justified.
