Small Fiber Neuropathy: Can Plasma Exchange Help?
The Agony of Small Fiber Neuropathy (SFN)
Imagine feeling like your feet are on burning coals, or experiencing sudden electric shocks, yet your skin looks normal. This is the reality of Small Fiber Neuropathy (SFN).
Unlike large nerve damage, SFN affects the tiny nerve endings that sense pain and temperature. It is often invisible to standard EMG tests, making it hard to diagnose and treat.
The Autoimmune Connection
Research estimates that up to 50% of SFN cases are autoimmune. The body attacks its own nerve fibers.
Common associated antibodies include:
- TS-HDS
- FGFR3
- Plexin D1
How TPE Treats SFN
If your neuropathy is driven by these antibodies, Therapeutic Plasma Exchange (TPE) can be a game-changer.
The Evidence
Studies have shown that TPE can reduce pain scores and improve autonomic function in patients with autoimmune SFN. By removing the antibodies attacking the nerve endings, TPE halts the assault, allowing the nerves to regenerate (which small fibers can do!).
What to Expect
- Pain Reduction: Many patients experience a decrease in the "burning" sensation.
- Improved Function: Better tolerance for temperature and touch.
- Trial Course: A trial of 5-7 sessions is often recommended to see if the patient is a "responder."
