Hi NRose
Welcome to NeuroTalk

.
TS-HDS is a component of the surfaces of neurons. What can happen is your immune system produces antibodies of the IgM class which react with it; this can lead to small fibre neuropathy.
As others have mentioned above, one way of treating this is use of IVIg (intravenous infusion of antibodies mainly of the IgG class).
This slightly technical link explains some of these ideas
