Oh, yeah...I'm Kate and I was diagnosed with HCV in July. Chances are more than good that I got it while being treated for Guillain-Barre Syndrome. Treatment for GBS is plasmapheresis (plasma exchange done with a dialysis machine).
GBS is a neurological syndrome that is usually triggered by a virus. The antibodies created to fight the virus don't shut off and begin attacking the myelin sheath on the nerves. Kinda like something munching on the insulation of a wire. Anyway, it can be mild or severe. It's painful - since the insulation is compromised, nerves sort of short circuit. It can also cause paralysis. Fortunately, GBS is fairly rare - 1 or 2 in 100,000 and recovery, while lengthy (2+ years), is around 85%.
If you want to know more, just let me know.
