Sarcoidosis and pain caused by small-fiber neuropathy
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This review discusses sarcoidosis, a chronic inflammatory illness, and its association with small-fiber neuropathy (SFN), which presents with peripheral pain (described as burning or shooting), autonomic dysfunction, allodynia, and hyperesthesia. The authors describe that diagnosis is typically based on clinical features combined with abnormal specialized tests, and that treatment aims to reduce pain, with total pain relief seldom achieved. The review notes interest in exploring the role of TNF-α in SFN pathogenesis in sarcoidosis, and highlights ARA 290, a nonhematopoietic erythropoietin analogue described as having anti-inflammatory and tissue-protective properties, as a novel therapeutic agent of interest to explore for SFN in sarcoidosis.
Abstract
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.
