I take Plaquenil (DMARD) daily for the Sjogren's itself and it's related symptoms and to help slow progression.

I also receive high dose IVIG for the neuropathy as a result of the Sjogren's...and it also benefits my primary immune deficiency (CVID).

The neuropathy damage is mostly permanent for me, as I went so long undiagnosed or treated. However, I do get some benefit from the IVIG to help with nerve/SFN related pain and some autonomic symptom relief.
