Asymmetric dimethylarginine (ADMA) levels are increased in patients with fibromyalgia: Correlation with tumor necrosis factor-alpha (TNF-alpha) and 8-iso-prostaglandin F-2 alpha (8-iso-PGF(2 alpha))

Objective: The aim of the study was to investigate serum levels of asymmetric dimethylarginine (ADMA), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and plasma levels of 8-iso-prostaglandin F-2 alpha (8-iso-PGF(2 alpha),) in patients with fibromyalgia
