What is small fiber neuropathy?

Small fiber neuropathy (SFN) is a type of peripheral neuropathy that specifically affects the small nerve fibers in the peripheral nervous system. These small fibers, known as “C fibers” and “A-delta fibers,” are responsible for transmitting sensations such as pain, temperature, and autonomic functions (e.g., heart rate, digestion, and sweating). Because these fibers are involved in sensory and autonomic functions, damage to them can result in a wide range of symptoms.

Key Features of Small Fiber Neuropathy

1. Affects Small Nerve Fibers: SFN primarily impacts small, unmyelinated or thinly myelinated nerve fibers that play a role in sensory perception (especially pain and temperature) and autonomic functions (like blood pressure regulation and sweating).
2. Symptoms: Common symptoms of SFN include:
   • Pain: Burning, stabbing, or shooting pain, often in the feet, hands, or legs. Pain is typically worse at night.
   • Tingling and Numbness: These sensations often start in the extremities (hands and feet) and may gradually spread.
   • Altered Sensation: Individuals may have abnormal responses to stimuli, such as increased sensitivity to pain (hyperalgesia) or pain from stimuli that shouldn’t cause pain, like light touch (allodynia).
   • Temperature Sensitivity: Difficulty perceiving changes in temperature, or extreme sensitivity to hot or cold temperatures.
   • Autonomic Symptoms: This can include dizziness or fainting due to blood pressure fluctuations, abnormal sweating (either too much or too little), gastrointestinal issues (e.g., constipation or diarrhea), and urinary problems.
3. Causes: Small fiber neuropathy can have many potential causes, including:
   • Diabetes: One of the most common causes of SFN is diabetes or prediabetes (impaired glucose tolerance).
   • Autoimmune Diseases: Conditions such as lupus, Sjögren’s syndrome, and celiac disease can lead to SFN.
   • Infections: Viral infections, such as HIV or hepatitis C, can damage small nerve fibers.
   • Genetic Mutations: Inherited forms of small fiber neuropathy, like those seen in certain familial cases of neuropathy, may be caused by specific genetic mutations.
   • Idiopathic Causes: In some cases, the cause of SFN is unknown, and the condition is classified as idiopathic small fiber neuropathy.
   • Medications and Toxins: Certain medications, especially chemotherapy drugs, and toxins like alcohol or heavy metals can damage small nerve fibers.
4. Diagnosis: Diagnosing small fiber neuropathy can be challenging because it doesn’t always show up on standard nerve conduction studies, which primarily measure large nerve fibers.
   • Skin Biopsy: This is one of the most common diagnostic tools for SFN. A small sample of skin is taken and analyzed under a microscope to measure the density of nerve fibers. A reduced density of small nerve fibers indicates SFN.
   • Quantitative Sudomotor Axon Reflex Test (QSART): This test measures the function of the small autonomic nerves that control sweating and can help diagnose SFN.
   • Autonomic Testing: Testing for autonomic dysfunction, such as heart rate variability, blood pressure responses, and sweating patterns, can help confirm the presence of small fiber damage.
5. Treatment: Treatment for SFN typically focuses on managing symptoms, as reversing nerve damage can be difficult.
   • Pain Management: Medications such as gabapentin, pregabalin, duloxetine, and amitriptyline may be used to manage neuropathic pain. Topical treatments like capsaicin cream or lidocaine patches can also provide relief.
   • Addressing the Underlying Cause: If a specific underlying condition is identified, such as diabetes or an autoimmune disorder, managing that condition can help reduce the progression of SFN.
   • Lifestyle Changes: For patients with SFN related to diabetes or prediabetes, controlling blood sugar levels through diet, exercise, and medication is crucial. Avoiding alcohol and other toxins is also recommended.
   • Physical Therapy: Physical therapy can help improve balance and mobility, particularly in those with significant sensory loss.
6. Prognosis: The course of small fiber neuropathy varies depending on the underlying cause. In some cases, SFN may remain stable or progress slowly, while in others, it may worsen over time, leading to increased pain and sensory loss. Treating the underlying cause, if identified, can often improve outcomes.

Conclusion

Small fiber neuropathy is a disorder that affects the small nerve fibers responsible for pain, temperature, and autonomic functions. Symptoms include pain, tingling, and autonomic dysfunction, and the condition can have various causes, including diabetes, autoimmune diseases, and infections. Diagnosis often involves skin biopsies and autonomic testing, and treatment focuses on managing symptoms and addressing underlying conditions when possible.
