Sarcoidosis and Pain Caused by Small-Fiber Neuropathy

Abstract EN

Sarcoidosis is a chronic inflammatory illness and small-fiber neuropathy (SFN) is one of the disabling and often chronic manifestations of the disease.

SFN presents with peripheral pain and symptoms of autonomic dysfunction.

The character of the pain can be burning or shooting.

Besides, allodynia and hyperesthesia can exist.

Diagnosis is usually made on the basis of clinical features, in combination with abnormal specialized tests.

The aim of treatment is often to reduce pain; however, total pain relieve is seldom achieved.

The role of TNF-α in the pathogenesis of SFN in sarcoidosis appears interesting to explore.

Novel therapeutic agents such as ARA 290, a nonhematopoietic erythropoietin analogue with potent anti-inflammatory and tissue protective properties, are interesting to explore in the treatment of SFN in sarcoidosis.
