Electrodiagnostic Features of Vasculitic Neuropathy
Electrophysiological studies of vasculitic neuropathy indicate that the best discriminators of vasculitis vs. other axonal neuropathies are the side-to-side differences between the same bilateral nerves. When the diagnosis is uncertain, nerve biopsy may be definitive.

Pyridoxine (B6) Toxicity in Chronic Idiopathic Axonal Polyneuropathy
In a careful prospective collection of features of chronic idiopathic axonal neuropathy, with retrospective ascertainment of vitamin B6 levels in the blood, the investigators reported there was no significant correlation between the severity of neuropathy symptoms and plasma B6 levels.

Incidence, Prevalence, and Long-Term Consequences of Small Fiber Neuropathy
Small fiber neuropathy (SFN), a subtype of peripheral neuropathy characterized by painful distal neuropathic pain and autonomic symptoms, is increasing in incidence. SFN associated with diabetes and other causes is more likely to progress to large-fiber polyneuropathy and have faster deterioration and higher disability compared to slow progression with idiopathic SFN. Glucose impairment, obesity, and elevated triglycerides are modifiable risk factors of idiopathic SFN. Although major disability and neurologic impairment are uncommon in this slowly progressive condition, higher mortality and cardiovascular events are noted in patients with SFN.

What Is Focal CIDP?
Chronic inflammatory demyelinating polyneuropathy (CIDP) usually is diagnosed in patients who have a generalized disorder. However, there are focal syndromes that have been observed and diagnosed under different names that meet many of the clinical and electrodiagnostic criteria of CIDP and may be referred to as “focal” CIDP.

Genetic Biomarkers of Immunoglobulin Response in Patients with CIDP
Nearly 25% of patients with chronic inflammatory demyelinating polyneuropathy (CIDP) have a poor response to intravenous immunoglobulin treatment. Variations in the PRF1 and FCGR2B genes in CIDP patients offer insights into the heterogenous treatment response.

Pitfalls in the Diagnosis of CIDP
Chronic inflammatory demyelinating polyradiculoneuropathy is commonly misdiagnosed. It is important to adhere to established diagnostic criteria and to regularly re-evaluate all patients given this diagnosis.

Gluten/Celiac Disease Neuropathy
Gluten neuropathy should be suspected in any patient who presents with a neuropathy and has a history of gastrointestinal disease. The diagnosis is made using blood serology plus intestinal mucosal biopsy.

Long-Term Treatment of Hereditary Amyloid Neuropathy with Patisiran
Hereditary transthyretin-mediated amyloidosis with polyneuropathy is effectively treated by patisiran, a lipid nanoparticle ribonucleic acid interference that binds to transthyretin (TTR) messenger RNA and inhibits TTR production in the liver, resulting in reduction of the serum TTR concentration. Treatment effect has been sustained during a five-year open-label extension study.

Cranial Neuropathy in CIDP
Cranial nerves are infrequently involved in typical chronic inflammatory demyelinating polyneuropathy, but involvement is more common in multifocal acquired demyelinating sensory and motor neuropathy (about 50%). The facial nerve is the most commonly affected cranial nerve, often bilateral.

Transthyretin Amyloidosis and Neuropathy
Wild-type transthyretin amyloidosis, referred to as “senile” amyloidosis previously, usually occurs in the aging population and affects the peripheral nerves and the heart. Usually, neurological symptoms precede cardiac symptoms.
